Sea Island Marine has designed and developed new construction ships, boats, barges, heavy lift vessels, and vessel conversions. Much of our work is major modifications to existing vessels.
These include extending a 366-ft pipe lay Barge by 90-ft, adding a starboard sponson, and a 1,500 M-ton revolving crane. All work was performed to ABS rules.
A new vertical tower was added to a 450-ft cable lay ship requiring redesign and new construction of the aft third of the ship.
All performed to DNV rules including SPS-199 safety, strength, stability, and load line. An onboard stability program was creation and load test for vessel cranes were also performed to Class requirements.
