Project Overviewx

Gambell’s community tank farm could not receive fuel from a barge and instead had to fly in small volumes of fuel at an outrageous expense due to a leak. HDL responded immediately and assisted the Alaska Energy Authority (AEA) with procuring pipe and valve materials and ensuring the materials made it on the barge to the community.

At the same time, HDL began designing the new barge header, including approximately 2,500 feet of buried, 3-inch, Schedule 80 gasoline and diesel pipelines installed between the existing barge mooring and the Corporation tank farm. The existing header pipe had corroded from exposure to the saltwater environment. HDL’s design solved this problem by installing fill in the depressions along the pipe alignment that collect seawater during storm surges.

Due to the COVID-19 pandemic, HDL’s engineers and surveyors could not travel to perform the site investigation and topographical survey. Instead, the team based the design on available LiDAR information from the Alaska Community Database and photographs from the tank farm operator to maintain the project schedule. HDL developed final design drawings and specifications within approximately 3 weeks of Notice to Proceed.
