In 2007 Marin Teknikk AS entered an agreement with Gulmar Offshore M.E. in Dubai for design and engineering of the company’s new diving vessels. The Korean shipbuilder Hanjin Heavy Industries in Busan, South Korea, was commissioned to build the vessels.
"Gulmar Atlantis" and "Gulmar Da Vinci" are sister vessels of MT6022 XL design, and both equipped to perform advanced diving, ROV and construction projects. The project is now completed, and both vessels are delivered. The last vessel, "Gulmar Da Vinci", left the shipyard last week and is on its way to Australia on its first mission. The other vessel, "Gulmar Atlantis", has already been commissioned a few months in Brazil.
The vessels have a length of 115.4 meters and a width of 22 meters, and the accommodation for 120 people is of high standard. The vessels have a structural deck behind the diving hangar at 1120 sq.m. and a ROV deck of 235 sq.m. Both vessels are equipped with two cranes, the largest is active heave compensated with a lifting capacity of 140 tons and the smallest offshore crane has a lifting capacity of 40 tons. Furthermore, the vessels are equipped with a large helicopter deck for Sikorsky S92 and Fi-Fi II firefighting system. Reinforcement is made on the stern for the mobilization of an 80 ton A-frame.
The vessels are built with a reinforced moon-pool for construction projects, in addition to two moon-pools for the diving system. The MT6022 XL DSCV design is equipped with an integrated "state-of-the-art 18 man twin bell Saturation" diving system, for diving down to a depth of 300 meters. Two hyperbaric lifeboats for safe evacuation of diving rob at a possible emergency is also present. The diving system has its own class notation SAT in DNV, where the ships are classified.
In addition to the large design and engineering package from Marin Teknikk AS, electrical engineering from Sebastian AS are included. The positive feedback from the yard and the ship crew is highly appreciated by Marin Teknikk.
