Project Summary

Beginning in the first quarter of 2020, Cornerstone Energy Service, Inc., served as the Engineering lead for an EPC team that was awarded the design of a Truck Offloading Station at an existing LNG facility in Brooklyn, NY. The project required the installation of a two bay, LNG truck offloading skid capable of offloading 200 gallons per minute of LNG into the existing tank system.

Challenges and Solutions

Cornerstone relied on our team of LNG experts to design perform stress modeling and design cooldown procedures for the LNG piping connection between the truck skid and tank. We achieved this by using existing low-pressure LNG loading pumps whose process mimicked a loading operation. Vapor leaving the truck skid was directed through an ambient heater followed by electric trim heater before delivery to the boil-off system.

Cornerstone also designed a spill containment trench beneath the trucking area. This concrete trench directed flow to an existing impoundment, with dry chemical skids incorporated for spill fire protection. Use of advanced 3D modeling techniques ensures accuracy in both design and constructability.

Hazard detection systems were a major scope item in this project. The truck station was designed to include gas, smoke, and flame detection devices, selected in accordance with FDNY requirements, as well as low temperature detectors within the spillway.

Our engineering team was an active participant in the process safety reviews conducted by the Client and critical to successfully navigating the project through the Client’s comprehensive process safety program.
