Oceanic King

The vessel is designed by Polar Ship Management AS in close cooperation with the naval architect Multi Maritime AS. The conversion by Ulstein Verft included the lengthening of the vessel by 22 m to accommodate hull integrated cable tanks, and add a hangar sheltering the cable laying equipment, with several special rooms for cable laying operations. "Oceanic King" has been developed in accordance with the demanding requirements for laying and maintenance of fibre-optic cables. The vessel features an efficient lay-out, providing a comprehensive arrangement of cable laying outfitting, spacious hotel facilities and a flexible, redundant and powerful propulsion and machinery package. "Oceanic King" is built with a hotel compliment of high standards and with capacity for 70 persons. Further with a hull integrated helicopter landing platform.

After delivery, the vessel had the A frame modified in order to be able to land it approx 1.5 m further to the front end of the deck. The vessel's first test task was to lay cables on 6,000 m depth.
