Six Thrusters Launched from Thrustmaster

By Maritime Reporter & Engineering News

Six Thrustmaster 5,000 hp (3,700 kW) Azimuth DP3 Thrusters classed by ABS were launched on November 25, 2013 during the OOS Gretha naming ceremony. The Brazil bound semisubmersible drilling rig was built at its ship yard in Yantai, China by CIMC Raffles and is due to work for Petrobras offshore. CIMC Raffles said it is the first asymmetric semisubmersible unit without bracing in the world. This reduces the towing resistance and dynamic positioning load, improving self propelled transit speed from an average 8 knots to more than 12 knots. The asymmetric pontoon outline, with pneumatic de-ballast system, also aids quick ballast adjustment, to suit heavy lifting operation.
