American Marine was hired to perform Diving Services for installing a subsea fiber optic cable from New York to the United Kingdom and Spain.
Diving services were conducted from a DP vessel per IMCA diving standards. Divers operated a cable plough system for cable burial and prepared the HDD nearshore connection to receive the subsea cable from offshore to the shore landing.
Diving was performed to strict IMCA standards with the highest level of Safety and Professionalism. American Marine received outstanding applause from our Client for our performance and for living up to our motto of “Performance Under Pressure.”
AMC was hired to service DCOR’s offshore deep water moorings for Platforms Esther, Edith, Eva, Gina, Gilda and Holly. Our work included the replacement of the dip sections, riser sections, associated hardware and installation of the refurbished mooring cans at the offshore platforms in Southern California.
AMC was hired as the prime contractor by the Los Angeles Department of Water and Power (LADWP) to remove, demo, and dispose of the retired submarine portion of the Sylmar Ground Return System. We removed 26 concrete underwater vaults that measured 11’x7’x6’ and weighed over 20 tons each, over 10,000 feet of submarine power cable, over 25 concrete clump weights, marker buoys, and other related debris about one mile offshore in Santa Monica Bay in depths ranging from 40-65 feet. All components of this system were taken back to our waterfront facility at Berth 270-271 in the Port of Los Angeles for demolition and land disposal. LADWP is a valued client of ours and we are happy to complete another safe and successful project for them!
AMC worked as a subcontractor to Manson Construction to handle all of the underwater scope of work for the wharf rehabilitation of Berths 226-236 in the Port of Los Angeles. We installed over 1,000 linear feet of octagonal and square concrete pile encasements utilizing the FX-70 fiberglass jacket system with marine-grade epoxy and underwater grout. This pile encasement work was a permanent solution to repair non-structural piles, structural piles, and broken piles that occurred over the life span of the wharf. AMC also repaired the slope underneath the Berth with underwater concrete pumping and bag placement to fill multiple voids. Lastly, our dive team completed the newly installed sheet pile wall by cutting it level at the desired underwater elevation and performing the underwater welding of the closure plate. Another successful project competed for the Port of LA!
AMC responded to complete this emergency repair to Cook’s Sea Cave for the City of San Diego to ensure stability of the roadway and utilities above. Our scope of diving work included underwater welding, rock drilling, underwater pumping of erodible concrete, installation of 135 ballast blocks integrated with filter fabric to act as a breakwater, installation of steel bulkhead and welding of closure plate. AMC was proud to offer our diving services to help maintain such an environmentally pristine area so that it can continue to be enjoyed by the local San Diego residents and visiting tourists.

AMI provided the dive team to set grade, install glulam’s and concreate boat panels, and pump concrete underwater panels to set in place. Divers also assisted with installing an aquadam to dewater the work site. This work was completed utilizing our Hot Water Arctic Dive System due to the freezing temperatures.
Commercial Diving in the Cook Inlet
4,1000 ft 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.
