Our facility is located adjacent to Interstate 5 on the North Portland Channel of the Columbia River.

Dockside repairs and retrofit for vessels up to 100 feet wide and 300 feet long are completed shoreside at this facility.  Larger vessels are accommodated at our new annex facility. Additionally, repairs are made at our customer's facility or shipside.

Our shop building and adjacent paved areas enable us to complete large fabrication projects.  Our shoreside work is completed alongside the shop where we have heavy equipment and large power sources to complete the work efficiently.

The 100 ton drydock (60' x 30') will lift most of our customers smaller work vessels and pleasure craft.

A rare quiet evening at our facility.  Photo taken by one of our neighbors, Margaret Johnson.  The photo is of the fishing vessel, Siberian Sea, just after coming off drydock and before starting its trip up the inland passage to Alaska.
