3103F.4 shall be used in lieu of those specified in ASCE/SEI 7 [4.1].

3103F.4 shall be used in lieu of those specified in ASCE/SEI 7 [4.1]. 3104F.5.6 Building structures. For buildings permanently attached to MOT structure, Section 3104F.5.4.1 shall be used to compute seismic loads. Computation of seismic effects shall consider: 1. Amplification of acceleration from ground to location of attachment of the building to the deck due to flexibility of the MOT structure, and 2. Amplification of acceleration due to flexibility of the building. For buildings permanently attached to the ground, seismic loads shall be computed using the procedures in ASCE/SEI 7 [4.1],…

B31.3 [12.4].

B31.3 [12.4]. The extreme thickness of insulation on cryogenic piping shall be taken into consideration during piping design. 2. All piping materials, including gaskets and thread compounds, shall be selected appropriate to the range of temperatures to which subjected. Piping that may be exposed to the low temperature of LNG or to the heat of an ignited spill, during an emer- gency where such exposure could result in a failure of the piping, shall comply with at least one of the following: (a) Made of material(s) that can withstand both the normal operating temperature and extreme temperature…

3112F.6 Mechanical components and systems.

3112F.6 Mechanical components and systems. 1. The CEA analysis shall be used to recommend acceptable cryogenic exposure durations for Safety Critical Components to produce CEA drawings. 2. ESD system components, which are exposed to cryogenic effects, shall be evaluated to confirm that the actuators will not be impaired by the potential exposures, thereby preventing the components from failing to a safe position. 3. Critical structural supports and equipment within the cryogenically exposed areas shall be provided with cryogenic insulation. The cryogenic insulation and passive fire protection…
