Section 3102F

Division 2

3102F.1.1 Purpose. Section 3102F defines minimum requirements for audit, inspection and evaluation of the structural, mechanical and electrical components and sys- tems.

3102F.1.2 Audit and inspections types. The audit and inspections described in this Chapter (31F) are:

1. Annual compliance inspection

2. Audits

3. Post-event inspection

Each has a distinct purpose and is conducted either at a defined interval (see Table 31F-2-1 and Section 3102F.3.3), for a significant change in operations, or as a result of a significant, potentially damage-causing event. In the time between audits and inspections, operators are expected to conduct periodic walk-down examinations of the MOT to detect potentially unsafe conditions.

3102F.1.3 Berthing systems. For the purpose of assigning structural ratings and documenting the condition of mechanical and electrical systems, an MOT shall be divided into independent “berthing systems.” A berthing system consists of the wharf and supporting structure, mechanical and electrical components that serve the berth and pipeline systems.

For example, a MOT consisting of wharves with three berths adjacent to the shoreline could contain three inde- pendent “berthing systems” if the piping does not route through adjacent berths. Therefore, a significant defect that would restrict the operation of one berth would have

no impact on the other two berths. Conversely, if a T-head Pier, with multiple berths sharing a trestle that supports all piping to the shoreline, had a significant deficiency on the common trestle, the operation of all berths could be adversely impacted. This configuration is classified as a single berthing system.

The physical boundaries of a berthing system may exclude unused sections of a structure. Excluded sections must be physically isolated from the berthing system. Expansion joints may provide this isolation.

3102F.1.4 Records. All MOTs shall have records reflect- ing current, “as-built” conditions for all berthing systems. Records shall include, but not be limited to modifications and/or replacement of structural components, electrical or mechanical equipment or relevant operational changes, new construction including design drawings, calculations, engineering analyses, soil borings, equipment manuals, specifications, shop drawings, technical and maintenance manuals and documents.

Chronological records and reports of annual inspec- tions, audits and post-event inspections and documenta- tion of equipment or structural changes shall be maintained.

Records shall be indexed and be readily accessible to the Division (see 2 CCR Section 2320 (c) (2)) [2.1].

3102F.1.5 Baseline assessment. If “as-built” or subse- quent modification drawings are not available, incomplete or inaccurate, a baseline inspection is required to gather data in sufficient detail for adequate evaluation.

The level of detail required shall be such that structural member sizes, connection and reinforcing details are doc- umented, if required in the structural analysis. In addition,

TABLE 31F-2-1 MAXIMUM INTERVAL BETWEEN UNDERWATER INSPECTIONS (YEARS) ¹

1. The maximum interval between Underwater Inspections shall be changed as appropriate, with the approval of the Division, based on the extent of deterioration observed on a structure, the rate of further anticipated deterioration or other factors. 2. Benign environments include fresh water and maximum current velocities less than 1.5 knots for the majority of the days in a calendar year. 3. Aggressive environments include brackish or salt water, polluted water or waters with current velocities greater than 1.5 knots for the majority of the days in the calendar year. 4. For most structures, two maximum intervals will be shown in this table, one for the assessment of construction material (timber, concrete, steel, etc.) and one for scour (last 2 columns). The shorter interval of the two should dictate the maximum interval used. 5. MOTs rated “Critical” will not be operational; and Emergency Action shall be required in accordance with Table 31F-2-6. 6. ICARs shall be assigned in accordance with Table 31F-2-4.

the strength and/or ductility characteristics of construc- tion materials shall be determined, as appropriate. Nonde- structive testing, partially destructive testing and/or laboratory testing methods may be used.

All fire, piping, mechanical and electrical systems shall be documented as to location, capacity, operating limits and physical conditions in the equipment layout dia- gram(s).

The Division may carry out annual inspections to determine the compliance status of the MOT with this code, based on the terminal’s audit and inspection findings and action plan implementation (see Section 3102F.3.9).

These inspections may include a visual and tactile assess- ment of structural, mechanical and electrical systems of the topside and underside areas of the dock, including the splash zone. Subject to operating procedures, a boat shall be pro- vided to facilitate the inspection of the dock undersides and piles down to the splash zone.

3102F.3.1 Objective. The objective of the audit is to review structural, mechanical and electrical systems on a prescribed periodic basis to verify that each berthing sys- tem is fit for its specific defined purpose. The audit includes above water and underwater inspections, engi- neering evaluation, documentation and recommended fol- low-up actions.

3102F.3.2 Overview. The audit shall include above water and underwater inspections, and structural, electrical and mechanical systems evaluations, with supporting docu- mentation, drawings and follow-up actions. Structural sys- tems shall include seismic, operational, mooring, berthing and geotechnical considerations. Mechanical systems shall include fire, piping/pipelines and mechanical equip- ment considerations. The audit is performed by a multi- disciplinary team of engineers, qualified inspectors and may include Division representatives.

The above water inspection involves an examination of all structural, mechanical and electrical components above the waterline. Structural defects and their severity shall be documented, but the exact size and location of each deficiency is typically not required.

The underwater inspection involves an examination of all structural, mechanical and electrical components below the waterline. A rational and representative under- water sampling of piles may be acceptable with Division approval, for cases of limited visibility, heavy marine growth, restricted inspection times because of environ- mental factors (currents, water temperatures, etc.) or a very large number of piles.

Global operational structural assessment rating(s) (OSAR), global seismic structural assessment rating(s) (SSAR) and global inspection condition assessment rat- ing(s) (ICAR) shall be assigned to each structure and over- all berthing system, where appropriate (Table 31F-2-4).

Remedial action priorities (RAP) shall be assigned for component deficiencies (Table 31F-2-5). Recommenda-

MARINE OIL TERMINALS

tions for remediation and/or upgrading shall be pre- scribed as necessary.

An audit is not considered complete until the audit report is received (in electronic and hard copy formats) by the Division.

3102F.3.3.1 Initial audit. For a new MOT or new berthing system(s), the initial audit of the “as-built” systems(s) shall be performed prior to commencement of operations.

3102F.3.3.2 Subsequent audits. A subsequent audit of each terminal shall be completed concurrently with the inspections (see Section 3102F.3.5). The audit team leader shall recommend either: (1) a default subse- quent audit interval of 4 years, or (2) an alternate interval, based on assessments of the structural, mechanical and electrical systems, and consideration of:

1. The extent of the latest deterioration and/or dis- repair,

2. The rate of future anticipated deterioration and/ or disrepair,

3. The underwater inspection guidance provided in Table 31F-2-1, and

4. Other specified factors.

Based on independent assessment of these factors, the Division may accept the audit team leader’s recom- mendation or require a different subsequent audit interval.

If there are no changes in the defined purpose (see Section 3102F.3.6.1) of the berthing system(s), relevant prior analyses may be referenced. However, if there is a significant change in the operations or condition of berthing system(s), a new analysis may be required.

The Division may require an audit, inspection or supplemental evaluations to justify changes in the use of the berthing system(s).

3102F.3.4.1 Project manager. The audit shall be con- ducted by a multidisciplinary team under the direction of a project manager representing the MOT. The proj- ect manager shall have specific knowledge of the MOT and may serve other roles on the audit team.

3102F.3.4.2 Audit team leader. The audit team leader shall lead the on-site audit team and shall be responsi- ble for directing field activities, including the inspec- tion of all structural, mechanical and electrical systems. The team leader shall be a California regis- tered civil or structural engineer and may serve other roles on the audit team.

The structural inspection shall be conducted under the direction of a registered civil or structural engineer.

All members of the structural inspection team shall be graduates of a 4-year civil/structural engineering,

or closely related (ocean/coastal) engineering curricu- lum, and shall have been certified as an Engineer-in- Training; or shall be technicians who have completed a course of study in structural inspections. The minimum acceptable course in structural inspections shall include 80 hours of instruction specifically related to structural inspection, followed by successful comple- tion of a comprehensive examination. An example of an acceptable course is the U.S. Department of Transpor- tation’s “Safety Inspection of In- Service Bridges.” Certification as a Level IV Bridge Inspector by the National Institute of Certification in Engineering Tech- nologies (NICET) shall also be acceptable [2.2].

For underwater inspections, the registered civil or structural engineer directing the underwater structural inspection shall also be a commercially trained diver or equivalent and shall actively participate in the inspection, by personally conducting a minimum of 25 percent of the underwater examination [2.2].

Each underwater team member shall also be a com- mercially trained diver, or equivalent. Divers perform- ing manual tasks such as cleaning or supporting the diving operation, but not conducting or reporting on inspections, may have lesser technical qualifications

[2.2].

A California regis- tered civil or structural engineer shall be in responsible charge of the structural evaluations.

3102F.3.4.5 Electrical inspection team. A registered electrical engineer shall direct the on-site team per- forming the inspection and evaluation of electrical components and systems.

3102F.3.4.6 Mechanical inspection team. A registered engineer shall direct the on-site team performing the inspection and evaluation of piping/pipeline, mechani- cal and fire components and systems, except the Fire Protection Assessment in accordance with Section 3108F.2.2.

3102F.3.4.8 Geotechnical analyst. A California regis- tered civil engineer with a California authorization as a geotechnical engineer shall perform the geotechnical evaluation required for the audit and all other geotech- nical evaluations.

The Division representative(s) may participate in any audit or inspection as observer(s). The Division shall be notified in advance of audit-related inspections. 3102F.3.5 Scope of inspections.

3102F.3.5.1 Structural inspections.

3102F.3.5.1.1 Above water structural inspection. The above water inspection shall include all acces- sible components above and below deck that are reachable without the need for excavation or exten- sive removal of materials that may impair visual inspection. The above water inspection shall include, but not be limited to, the following:

1. Piles

2. Pile caps

3. Beams

4. Deck soffit

5. Bracing

6. Retaining walls and bulkheads

7. Connections

8. Seawalls

9. Slope protection

10. Deck topsides and curbing

11. Expansion joints

12. Fender system components

13. Dolphins and deadmen

14. Mooring points and hardware

15. Navigation aids

16. Platforms, ladders, stairs, handrails and gangways

17. Backfill (sinkholes/differential settlement)

The underwater inspection shall include all compo- nents below deck to the mudline, including the slope and slope protection, in areas immediately sur- rounding the MOT. The water depth at the berth(s) shall be evaluated, verifying the maximum or loaded draft specified in the MOT’s Operations Manual (2 CCR 2385) [2.1].

The underwater structural inspection shall include the Level I, II and III inspection efforts, as shown in Tables 31F-2-2 and 31F-2-3. The underwater inspec- tion levels of effort are described below, per [2.2]:

Level I—Includes a close visual examination, or a tactile examination using large sweeping motions of the hands where visibility is limited. Although the Level I effort is often referred to as a “swim-by” inspection, it must be detailed enough to detect obvi- ous major damage or deterioration due to overstress or other severe deterioration. It should confirm the continuity of the full length of all members and detect undermining or exposure of normally buried ele- ments. A Level I effort may also include limited prob- ing of the substructure and adjacent channel bottom.

Level II—A detailed inspection which requires marine growth removal from a representative sam- pling of components within the structure. For piles, a 12-inch high band shall be cleaned at designated locations, generally near the low waterline, at the

mudline, and midway between the low waterline and the mudline. On a rectangular pile, the marine growth removal should include at least three sides; on an octagon pile, at least six sides; on a round pile, at least three-fourths of the perimeter. On large diam- eter piles, 3 ft or greater, marine growth removal should be effected on 1 ft by 1 ft areas at four loca- tions approximately equally spaced around the perimeter, at each elevation. On large solid faced ele- ments such as retaining structures, marine growth removal should be effected on 1 ft by 1 ft areas at the three specified elevations. The inspection should also focus on typical areas of weakness, such as attach- ment points and welds. The Level II effort is intended

MARINE OIL TERMINALS

to detect and identify damaged and deteriorated areas that may be hidden by surface biofouling. The thoroughness of marine growth removal should be governed by what is necessary to discern the condi- tion of the underlying structural material. Removal of all biofouling staining is generally not required.

Level III—A detailed inspection typically involv- ing nondestructive or partially-destructive testing, conducted to detect hidden or interior damage, or to evaluate material homogeneity. Level III testing is generally limited to key structural areas, areas which are suspect or areas which may be represen- tative of the underwater structure.

UNDERWATER INSPECTION LEVELS OF EFFORT [2.2]

1. The minimum inspection sampling size for small structures shall include at least two components. LF = Linear Feet; SF = Square Feet; N/A = Not Applicable

MARINE OIL TERMINALS

3102F.3.5.2.1 Coated components. For coated steel components, Level I and Level II efforts should focus on the evaluation of the integrity and effectiveness of the coating. The piles should be inspected without damaging the coating. Level III efforts should include ultrasonic thickness measurements without removal of the coating, where feasible.

3102F.3.5.2.2 Encased components. For steel, con- crete or timber components that have been encased, the Level I and II efforts should focus on the evalua- tion of the integrity of the encasement. If evidence of significant damage to the encasement is present, or if evidence of significant deterioration of the under- lying component is present, then the damage evalua- tion should consider whether the encasement was provided for protection and/or structural capacity. Encasements should not typically be removed for an audit.

For encasements on which the formwork has been left in place, the inspection should focus on the integrity of the encasement, not the formwork. Level I and Level II efforts in such cases should concentrate on the top and bottom of the encase- ment. For concrete components, if deterioration, loss of bonding or other significant problems with the encasement are suspected, it may be necessary to conduct a special inspection, including coring of the encasement and laboratory evaluation of the materials.

For steel, concrete or timber components that have been wrapped, the Level I and II efforts should focus on the evaluation of the integrity of the wrap. Since the effectiveness of a wrap may be compromised by removal, and since the removal and re-installation of wraps is time-consuming, it should not be rou- tinely done. However, if evidence of significant dam- age exists, or if the effectiveness of the wraps is in question, then samples should be removed to facili- tate the inspection and evaluation. The samples may be limited to particular zones or portions of mem- bers if damage is suspected, based on the physical evidence of potential problems. A minimum sample size of three members should be used. A five-percent sample size, up to 30 total members, may be ade- quate as an upper limit.

For wrapped timber components, Level III efforts should consist of removal of the wraps from a representative sample of components in order to evaluate the condition of the timber beneath the wrap. The sample may be limited to particular zones or portions of the members if damage is suspected (e.g., at the mudline/ bottom of wrap or in the tidal zone). The sample size should be determined based on the physical evidence of potential problems and the aggressiveness of the environment. A minimum sample size of three members should be used. A five-

percent sample size, up to 30 total members, may be adequate as an upper limit.

The mechanical and electrical inspections shall include but not be limited to the following:

1. Loading arms

2. Cranes and lifting equipment, including cables

3. Piping/manifolds and supports

4. Oil transfer hoses

5. Fire detection and suppression systems

6. Vapor control system

7. Sumps/sump tanks

8. Vent systems

9. Pumps and pump systems

10. Lighting

11. Communications equipment

12. Gangways

13. Electrical switches and junction boxes

14. Emergency power equipment

15. Air compressors

16. Meters

17. Cathodic protection systems

18. Winches

19. ESD and other control systems

20. Ladders

All alarms, limit switches, load cells, current meters, anemometers, leak detection equipment, etc., shall be operated and/or tested to the extent feasible, to ensure proper function.

Utility, auxiliary and fire protection piping shall have external visual inspections, similar to that defined in Section 10.1 of API RP 574 [2.3] (N/E).

During each audit, a comprehensive corrosion inspection shall be per- formed by a qualified engineer or technician. This inspection shall include all steel and metallic compo- nents, and any installed cathodic protection system (CPS). CPS inspection during the audit is not intended to substitute for required testing and maintenance per- formed on a more frequent schedule per Section 3111F.10. All inspection results shall be documented, and shall be used in the corrosion assessment (Section

Submerged wharf structures and associated cathodic protection equipment (if installed) shall be inspected per [2.2]. Above water structures, ancillary equipment, supports and hardware shall be visually inspected. Corrosion inspection of utility, auxiliary and fire pipelines shall be done per Section 3102F.3.5.3.

For oil pipelines in an API 570 [2.4] inspection program, a corrosion inspection is not required as part

of the audit; however, the latest inspection results, cal- culations and conclusions shall be reviewed, and any significant results shall be included in the corrosion assessment.

3102F.3.6.1 Terminal operating limits. The physical boundaries of the facility shall be defined by the berth- ing system operating limits, along with the vessel size limits and environmental conditions.

The audit shall include “Terminal Operating Lim- its” (TOLs) diagrams, which provide a concise state- ment of the purpose of each berthing system in terms of operating limits for representative vessel size ranges and mooring configurations approved to call and/or conduct transfer operations at the MOT. This descrip- tion shall include, the minimum and maximum vessel sizes, including Length Overall (LOA), beam and maxi- mum draft with associated displacement (see Figure 31F-2-1).

In establishing limits for both the minimum and maximum vessel sizes, due consideration shall be given to water depths, dolphin spacing, fender system limita- tions, manifold height and hose/loading arm reach, with allowances for tidal fluctuations, surge and drift.

Maximum wind, current or wave conditions, or combinations thereof, shall be clearly defined as limit- ing conditions for vessels at each berth, both with and without active product transfer.

The TOLs shall be explicitly presented to facilitate implementation by the MOT operator, such as through incorporation in the MOT’s Operations Manual (2 CCR 2385 [2.1]). The TOLs shall allow for direct com- parison of operating limits and output from monitoring systems and instrumentation (i.e., anemometers, cur- rent meters, tension monitoring systems, velocity moni- toring systems). Design and implementation considerations shall include, but not be limited to:

1. Units of measurement (i.e., English vs. System International units)

2. Directionality (i.e., current restrictions “to”, wind restrictions “from”, true or magnetic north)

3. Parameters of monitoring systems and instru- mentation (i.e., duration/averaging of readings, elevation/depth of readings, distance/location of readings)

Mooring and berthing analyses shall be performed in accordance with Section 3105F. The analyses shall be consistent with the terminal operating limits and the structural configuration of the wharf and/or dolphins and associ- ated hardware.

Based on inspection results, analyses and engineer- ing judgment, mooring and berthing OSARs shall be assigned on a global basis, independently for each

MARINE OIL TERMINALS

structure and overall berthing system. The OSARs defined in Table 31F-2-4 shall be used for this purpose. The mooring and berthing OSARs document the berth- ing system(s) fitness-for-purpose.

A structural evaluation, includ- ing a seismic analysis, shall be performed in accor- dance with Sections 3103F through 3107F. Such evaluation shall consider local or global reduction in capacity, as determined from the inspection.

Based on inspection results, structural analyses and engineering judgment, OSARs (for operational load- ing) and SSARs shall be assigned on a global basis, independently for each structure, structural system(s) and berthing system(s), as appropriate. The OSARs and SSARs defined in Table 31F-2-4 shall be used for this purpose and document the structural and/or berthing system(s) fitness-for-purpose.

Based on inspection results and engineering judg- ment, ICARs shall be assigned on a global basis, inde- pendently for each above and underwater structure, structural system and berthing system, as appropriate. The ICARs defined in Table 31F-2-4 shall be used for this purpose.

Structural component deficiencies assigned RAPs as per Table 31F-2-5 shall be considered in the OSARs, SSARs and ICARs. The assigned ratings shall remain in effect until all the significant corrective action has been completed to the satisfaction of the Division, or until completion of the next audit.

An evaluation of all mechanical and electrical systems and components shall be performed in accordance with Sec- tions 3108F through 3111F of these standards. Forces and imposed seismic displacements resulting from the structural analysis shall be considered in the pipeline stress analyses (Section 3109F.3), and the piping/pipe- lines shall be assigned SSARs in Table 31F-2-7B. Mechanical and electrical component deficiencies shall be assigned ratings from Table 31F-2-5.

A compre- hensive assessment shall be performed by the corrosion specialist (Section 3102F.3.4.7), to determine the exist- ing and potential corrosion using “as-built” drawings and specifications. This assessment shall comprise all steel and metallic components, including the structure, pipelines, supports and other MOT ancillary equip- ment. This assessment shall also include prestressed and reinforced concrete structures.

If cathodic protection is installed to protect wharf structures and/or pipelines, the following records shall be evaluated for each system:

1. CPS equipment condition and maintenance

2. Impressed current readings (as applicable)

3. Potential survey results

3. Mooring and berthing analyses

4. Structural and seismic analyses and calculations

5. Geotechnical report

6. MOT Fire Protection Assessment

7. Pipeline stress and displacement analyses

8. Mechanical and electrical system documentation

9. Corrosion assessment

10. Photographs, sketches and supporting data shall be included to document typical conditions and referenced deficiencies, and to justify the assess- ment ratings and the remedial action priorities RAPs assigned.

The operator is responsible for correction of deficiencies between audits. Prior to implementation, projects shall be submitted for Division review in accordance with Sec- tion 3101F.8.3. During project implementation, the Divi- sion shall be informed of any significant changes. After project completion, “as-built” documentation, including drawings, calculations and analyses, shall be submitted to the Division.

Executive Summary Tables shall be updated by the operator and submitted to the Division at least annually.

A post-event inspection is a focused inspection following a significant, potentially damage-causing event such as an earthquake, storm, vessel impact, fire, explosion, construction incident or tsunami. The primary purpose is to assess the integrity of structural, mechanical and electrical systems. This assess- ment will determine the operational status and/or any reme- dial measures required.

3102F.4.1 Notification and action plan. Notification as per 2 CCR 2325(e) [2.1] shall be provided to the local area Division field office. The notification shall include, as a minimum:

1. Brief description of the event 2. Brief description of the nature, extent and signifi- cance of any damage observed as a result of the event 3. Operational status and any required restrictions 4. Statement as to whether a Post-Event inspection will be carried out The Division may carry out or cause to be carried out, a post-event inspection. In the interim, the Division may direct a change in the operations manual, per 2 CCR 2385 (f)(3) [2.1].

If a post-event inspection is required, an action plan shall be submitted to the Division within five (5) days after the event. This deadline may be extended in special cir- cumstances. The action plan shall include the scope of the inspection (above water, underwater, electrical, mechani- cal systems, physical limits, applicable berthing systems, etc.) and submission date of the final report. The action plan is subject to Division approval.

3102F.4.2 Inspection team. The qualifications of the inspection team shall be the same as those prescribed in Section 3102F.3.4. Division representatives may partici- pate in any post-event inspection, as observers, and may provide guidance.

3102F.4.3 Scope. The post-event inspection shall focus on the possible damage caused by the event. General obser- vations of long-term or preexisting deterioration such as significant corrosion-related damage or other deteriora- tion should be made as appropriate, but should not be the focus of the inspection. The inspection shall always include an above-water assessment of structural, mechan- ical and electrical components.

The inspection team leader shall determine the need for, and methodology of, an underwater structural assess- ment, in consultation with the Division. Above water observations, such as shifting or differential settlement, misalignments, significant cracking or spalling, bulging, etc., shall be used to determine whether or not an under- water assessment is required. Similarly, the inspection team leader shall determine, in consultation with the Divi- sion, the need for, and methodology of, any supplemental inspections (e.g., special inspections (see Section 3102F.3.5.3).

The following information may be important in deter- mining the need for, and methodology of, the post-event inspection:

1. Earthquakes or vessel or debris impact typically cause damage both above and below the waterline. Following a major earthquake, the inspection should focus on components likely to attract highest lateral loads (batter or shorter piles in the rear of the structure, etc.). In case of vessel or debris impact, the inspection effort should focus on compo- nents in the path of the impact mass.

2. Major floods or tsunamis may cause undermining of the structure and/or scouring at the mudline.

3. Fire damage varies significantly with the type of construction materials but all types may be adversely affected. Special inspections (sampling and laboratory testing) shall be conducted, as deter- mined by the inspection team leader, in order to determine the nature and extent of damage.

4. High wind or wave events often cause damage both above and below the waterline. An underwater inspection may be required if damage is visible above the waterline. Structural damage may be potentially increased if a vessel was at the berth during the event. The effects of high wind may be most prevalent on equipment and connections of such equipment to the structure.

The methodology of conducting an underwater post- event inspection should be established with due consider- ation of the structure type and type of damage anticipated. Whereas slope failures or scour may be readily apparent in waters of adequate visibility, overstressing cracks on

piles covered with marine growth will not be readily apparent. Where such hidden damage is suspected, marine growth removal should be performed on a representative sampling of components in accordance with the Level II effort requirements described in Section 3102F.3.5.2. The cause of the event will determine the appropriate sample size and locations.

3102F.4.4 Post-event ratings. A post-event rating [2.2] shall be assigned to each berthing system upon completion of the inspection (see Table 31F-2-9). All observations of the above and under water structure, mechanical and electrical components and systems shall be considered in assigning a post-event rating.

Ratings should consider only damage that was likely caused by the event. Pre-existing deterioration such as cor- rosion damage should not be considered unless the struc- tural integrity is immediately threatened or safety systems or protection of the environment may be compromised.

Assignment of ratings should reflect an overall charac- terization of the berthing system being rated. The rating shall consider both the severity of the deterioration and the extent to which it is widespread throughout the facility. The fact that the facility was designed for loads that are lower than the current standards for design should have no influence upon the ratings.

3102F.4.5 Follow-up actions. Follow-up actions shall be assigned upon completion of the post-event inspection of each berthing system. Table 31F-2-5 specifies remedial action priorities for deficiencies. Table 31F-2-6 specifies various follow-up actions. Multiple follow-up actions may be assigned; however, guidance should be provided as to the order in which the follow-up actions should be carried out. Follow-up actions shall be subject to Division approval.

3102F.4.6 Documentation and reporting. Documentation of the specific attributes of each defect shall not be required during a post-event inspection. However, a nar- rative description of significant damage shall be used. The description shall be consistent with and shall justify the post-event rating assigned.

A report shall be prepared and submitted to the Divi- sion upon completion of the post-event inspection and shall, at a minimum, include:

1. Brief description of the facility including the physi- cal limits of the structure, type of construction mate- rial(s), and the mechanical and electrical systems present

2. Brief description of the event triggering the inspec- tion

3. Scope of the inspection (above water, underwater, electrical or mechanical)

4. Date of the inspection

5. Names and affiliations of inspection team

6. Description of the nature, extent and significance of any observed damage resulting from the event

7. Photographs should be provided to substantiate the descriptions and justify the condition rating

8. Assignment of a post-event rating

9. Statement regarding whether the facility is fit to resume operations and, if so, under what conditions

10. Assignment of follow-up action(s)

11. Inspection data, drawings, calculations and other relevant engineering materials

12. Signature and stamp of team leader(s)

3102F.4.7 Action Plan Report. Upon completion of all actions delineated in the action plan, a final report shall be submitted to the Division to document the work com- pleted. Supporting documentation such as calculations or other relevant data shall be provided in appendices.
