Cascade General has access to the largest steel fabrication facility in the region. The shop has a clear height of 65 feet (19.8 m) and an overhead crane capable of handling 35 tons (31.7 tonnes). We have in-house rolling and burning expertise with three burning tables.

Cascade General has access to an extensive on-site inventory of steel plate from 3/16" to 3 1/2" (4.7 mm to 88.9 mm) (DH-36 to 1 1/2" (38.1 mm) and mild steel to 3 1/2" (88.9 mm) as well as a large selection of bar stock. The proximity of local steel suppliers ensures adequate materials are readily available.

Cascade General developed the "Evacuation Box" - a vacuum box divers can easily attached to a ship's exterior hull below the waterline to remove water from the area surrounding a hull fracture, allowing underwater welding. The evacuation box is a cost-effective, ABS and US Coast Guard-approved alternative to dry docking in certain applications.

We have extensive experience with large-scale prefab and heavy lift projects. The equipment and facilities of the Portland Shipyard- including 17 heavy-lift cranes to 120 long tons (122 tonnes) capacity and 550,000 square feet (51,096 square meter) of craft shops - are laid out to further enhance the efficiency of your repair job.

Results? Just ask the owners of the drill ship Glomar Explorer - we installed 2,250 tons (2,041 tonnes) of steel double bottoms, decks, and bulkheads, ahead of schedule and on budget. Cascade General routinely meets the requirements of owners whose specifications exceed regulatory requirements and who demand attention to detail.

No matter how big or complex the job, we have handled it.
