National Grid LNG Tank Thermal Protection

Structural Thermal Barrier

National Grid desired a consultant to engineer a thermal protection system that would protect their LNG tank assets at the Salem, Lynn, and Providence LNG facilities against the elevated temperatures they could be exposed to in the event of a pressurized LNG fire, also known as a “jet fire” that could occur in the tank process areas.

ODIN was engaged to identify feasible products that could provide the desired protection and then engineer and design the means of installation that would minimize impact to the existing plant infrastructure around the tank.  ODIN identified a thermal coating that would provide the desired protection levels when applied to stainless steel panels.  ODIN then designed modifications to the existing splash and ice shield infrastructure at each plant to allow for the installation of the panels between the process piping and the outer tank wall.  Secondary means of protection were also engineered to reduce the chance of a jet fire developing which included bonnet shields over valves and guards over flanged connections.

ODIN’s services on this project included feasibility reports, a detailed engineering study, 3D scanning of the tank process areas of each facility, structural engineering, and drafting of “Issued for Construction” drawing packages detailing all necessary work for the installation.  Construction at each facility is scheduled to begin with Providence in the summer of 2023 with Salem and Lynn to follow.
