Industrial Fabrication

Greenberry Industrial was contracted by the project owner to provide modular fabrication and construction services for work associated with its Arctic Containment System (ACS) Project. The ACS is a first-of-its-kind prototype spill containment system designed to support offshore oil exploration activities in Arctic waters. Under fast-track conditions from day one, the original scope of the project included fabrication and assembly of the two primary modules of the ACS, the Process Module (for oil/water separation) and the Sub-Sea Module (for below-surface spill location, containment and recovery). As General Contractor, Greenberry provided bulk materials procurement, structural steel and pipe spool fabrications, field assembly and marine installation of the modules onto the 315-foot x 107-foot Arctic Challenger barge moored at the Port of Bellingham Shipping Terminal.

Fabrication of both module structures, various other structures and enclosures totaling more than 1,300 tons
Extensive low-temp welding procedures for Arctic applications to -50 degrees F
Fabrication of 6,500 feet of piping systems with supports
Fabrication of 1,000 feet of HVAC ductwork with supports
Fabrication of 4,000 feet of fire systems
Fabrication of black/gray water, potable water, diesel, and fire water systems totaling 3,000 feet
2.5 million weld inches; only 0.36% weld test failure rate (using X-ray, Mag particle and Dye penetrant methods)
