Honghua Offshore Oil & Gas Equipment Company in Jiangsu, China, has extended the weight limit on lifting a complete vessel for launching with its first ship, an IMT982 platform supply vessel (PSV).

Nordic Trym was launched in a unique way through the first use of the yard’s new gantry crane, which has a capacity of 22,000 tonnes SWL and is seen as the world’s largest moving gantry crane.

Designed by Offshore Ship Designers’ UK arm, OSD-IMT, the 3,900dwt PSV is 83.2m long with a deck area of 900m² and tankage for 1,360m³ of fuel oil, 770m³ of potable fresh water, 1,010m³ of liquid mud/brine, 1,350m³ of drill water/water ballast, and 170m³ of base oil, as well as storage for 278m³ of dry bulk.

Nordic Trym’s diesel-electric propulsion system (chosen for fuel economy and efficiency) uses four main diesel generators, two 1900kW frequency-controlled electric motor-driven azimuth thrusters for main propulsion, and two 800kW frequency-controlled, electric motor-driven, tunnel thrusters fitted forward.

The vessel is classed with Lloyd’s Register and fitted with a DP2 system. It has accommodation for a crew of 27 persons and has a trial speed of 14.0kt.

Delivery of the Nordic Trym to its new owners, Nordic Offshore Supply Limited, is expected in April 2015.
