Commercial Diving in the Cook Inlet

Project Description: 4,1000ft of the subsea oil pipeline was cut out and replaced with sectional spool pieces towed from shore.

American Marine Divers ensured each spool piece landed in a small target box next to an active gas pipeline. This requires precise movements, and Divers will have the know-how and experience working in the Cook Inlet environment.

Our divers utilized a metrology jig at each connection to fabricate the closure spools. These closure spools ranged from 20-50ft with various configurations to ensure the lines flanged together.

Divers cut both ends of the existing line utilizing a hydraulic Wach Saw and installed collet grips on each end. Creative solutions such as closure spools that went over existing lines on the seafloor were installed.

American Marine was proud to play the subsea experts in this technically challenging project.
