The offshore construction vessel ‘Polar Onyx’ was delivered on 4 March 2014 from Ulstein Verft to GC Rieber Shipping, as the latest addition to their growing investments into the subsea segment.
The vessel’s first assignment will be to work for deepwater projects serving as pipelay support vessel for Petrobras offshore Brazil.
The 130-metre long and 25-metre wide ‘Polar Onyx’ is based on ULSTEIN’s SX121 design, a design which is generally designed to operate in the IMR/SURF construction market, with high capacity for flexible pipe cargo below deck and on main deck.
‘Polar Onyx’ can accommodate 130 persons, and complies with the latest international environmental standards. She is certified according to Special Purpose Ships (SPS) and Clean Design and carries a Green Passport.
The vessel has a large construction/cargo deck area of 1,700 m2. She is equipped with an AHC offshore crane capable of lifting 250 tonnes at 14-metre outreach, and a 12-tonne AHC offshore crane.
She will also carry two new work class ROVs, one to be deployed through a moon pool, the other over the starboard side.
The vessel is classed according to DNV, and meets the highest standards for station keeping, redundancy and dynamic positioning (DP3), with additional redundancy on all major components on board.
