Hawaii- USS Bowfin Drydock


AMC was hired to prepared the 80 year old Bowfin submarine to be towed from the Pacific Fleet Submarine Museum at Pearl Harbor to Pacific Shipyards International.

The USS Bowfin has an incredible history and importance in protecting the Safety and Freedom of our great Country. AMC was honored to play an integral part in maintaining these historical submarine and the US Navy.

Salvage of Sailboat S/V Christiana


Sailboat Christiana broke free of her mooring offshore Honolulu Harbor and drifted into the jetty at the Harbor entrance at sunset.

Fuel and oil was seen leaking from the vessel which poised a critical risk to the navigation as the only point of entry to Honolulu Harbor for freighters, cruise ships, and rescue vessels.

Harbors Divisions of Hawaii Department of Transportation (HDOT) hired AMC to provide emergency response services in order to safely remove the vessel blocking vessel traffic while minimize the hazards to the environment.

Divers were deployed immediately at night to located the vessel and rig it for lifting and removal out of the channel.

Pacific Environmental Corporation (PENCO) was brought in to remove all the hazardous material. This was a successful critical project completed under pressure to get the Harbor operational again.

See article in the photo gallery below discussing the project in the local Honolulu news.

Subsea Fiber Optic Cable Installation

American Marine Corporation (AMC) was hired to provide ROV monitoring and assistance with installing a subsea fiber optic cable from Asia to California.

AMC utilized our advantageous waterfront facility located in the Port of Los Angeles to perform a large mobilization of the offshore vessel for operations.

We had to perform various retrofits to accommodate the equipment on board the vessel and our ABS certified welding team was critical in making this happen in short order. This project required cable monitoring up to 2,000m water depth.

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.”

Deep Water Mooring Service

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.

Submarine Portion Removal of Old Sylmar Ground Return System

Submarine Portion Removal of Old Sylmar Ground Return System

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!

Port of Los Angeles: Berths 226-236 Terminal Improvement

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.
