Chapter 31F — MARINE OIL TERMINALS

Section 3112F — REQUIREMENTS SPECIFIC TO MARINE TERMINALS THAT TRANSFER LNG

2025 California Building Code (Title 24, Part 2) · 2025 edition · updated 2026-07-27 · California

Italicized text is a California amendment to the model code, as printed in the official publication.

3112F.1 Purpose and applicability.

Section 3112F provides minimum requirements specific to onshore marine terminals that transfer LNG. Sections 3101F through 3111F are also applicable, as appropriate. Offshore marine terminals that transfer LNG are subject to a case-by-case review and approval by the Division.

3112F.2 Risk and Hazards Analyses.

1. Prior to LNG transfer at marine terminal, a hazards identification exercise shall be carried out to isolate potential internal and external events that may cause a spill and/or impact to public health, safety and the environment. 2. Hazards analysis shall consider every component, part of a structure, equipment item, and system, whose failure could cause a major accident, result in unacceptable incident escalation beyond the design basis, or adversely affect the potential for the passive and active systems to control or shutdown the facility. Safety Critical Components and Safety Critical Systems shall be identified.

3. Consequence models shall be developed for credible scenarios to identify Lower Flammability Limit (LFL) hazard regions. Release diameters shall include, at a minimum, 3mm, 10mm and 50 mm sizes. Scenarios involving the marine loading arms shall consider a full bore release.

4. Consequence models shall develop radiant heat zones from jet and pool fires for the 25 kW/m [2] , 12.5 kW/m [2] , 5 kW/m [2] and 1.6 kW/m [2] thermal endpoints. 5. A Cryogenic Exposure Analysis (CEA) shall be conducted to identify equipment and structures susceptible to cryogenic spray and pool exposure due to LNG releases from different size holes. 6. A Facility Essential Systems Survivability Assessment (ESSA) shall be conducted to determine the survivability of the Safety Crit- ical Components. 7. Impact on Safety Critical Components and Systems shall be mitigated.

3112F.3 Specific berthing and mooring considerations.

In addition to the minimum design requirements for berthing and mooring in Sections 3103F, 3105F and 3107F of this code, the following shall be satisfied: 1. Wind force and moment coefficients for LNG vessels shall be used in accordance with Appendix A of OCIMF MEG 3 [12.1], as appropriate. 2. The limiting environmental criteria for which the LNG carrier may safely remain berthed at the terminal shall be determined using dynamic mooring analysis. 3. Real time monitoring and recording of environmental conditions including wind, current and waves shall be conducted to assist in mooring system management. 4. Vessel hull pressure shall be considered in fender analyses and design.

3112F.4 Fire protection.

A Fire and Explosion Hazard Analysis (FEHA) for potential pool fires, jet fires and flash fires, considering LNG releases from different size holes, as specified in Section 3112F.2, shall be conducted and result in recommendations regarding: 1. Type, quantity and location of fire and gas detection devices to detect potential fires and/or gas releases in a specified time frame

2. Fire suppression coverage, including fixed and portable systems, and equipment necessary to allow the design scenarios to be mitigated and/or extinguished 3. Design application rates for required fire protection systems 4. Firefighting requirements, including an analysis of the capability of response by other facilities, USCG and federal, state and local agencies

Critical structural supports and equipment within the fire exposed areas identified in the FEHA shall be provided with passive fire protection designed for the duration identified in the analysis.

Emergency shutdown (ESD) systems shall be provided, in accordance with API RP 14C [12.2] and Section 12.3 of NFPA 59A [12.3], to shut down the flow of LNG to/from the terminal and shut down equipment whose continued operation could add to or prolong an emer- gency event.

The ESD system shall be of a failsafe design or shall be otherwise installed, located or protected to minimize the possibility that it becomes inoperative in the event of an emergency or failure at the primary control system. ESD system components that may be exposed to fire effects shall be evaluated to confirm that the actuator operation will not be impaired.

3112F.5 LNG pipelines.

1. All pipe specified for use in cryogenic service shall be furnished in accordance with Paragraph 323.2.2A and Table A-1 of ASME
