Zheijang Shipyard, part of the Sinopacific Shipbuilding Group, recently delivered the Ungundja, the first of 10 DP-3, 100-meter GPA 696 IMR (Inspection, Maintenance & Repair) vessels to Paris-based Bourbon Offshore.
The highly maneuverable DP-3 and FiFi-1 certified GPA 696 IMR vessels are equipped with three 1,686 kW azimuthing drives, two 843 kW tunnel bow thrusters, one 843 kW drop-down azimuthing bow thruster delivered by Schottel and six 1,235 kW Cummins generators, as well as one 1,235 kW auxiliary generator and one 450 kW emergency generator.
The configuration of the environmentally friendly diesel-electric propulsion system, including two engine and two electrical rooms, creates full redundancy in accordance with DP-3 requirements. The diesel-electric propulsion system also results in reduced maintenance cost and improved station-keeping at offshore installations, and significantly increases crewmember safety. Because of its design and standardization, the GPA 696 IMR series can compete with more expensive, similar-sized vessels, reducing operational cost to the customer by up to 20%, according to Guido Perla & Associates.
The deck equipment of the 100-meter vessels includes one 150 MT at 10 m radius main crane, which can lower packages to a depth of 3,000 meters and one 40 MT at 9 m radius deck crane. Both cranes, with built-in swell compensation systems, cover the entire 1,200 m² deck surface to ensure handling and storage of packages over the entire area. The SOLAS-certified IMR vessels also have significant below-deck cargo capacities, capable of carrying 380 m³ of methanol, 2,541 m³ ship‘s ballast, 1,080m³ fuel oil and 749 m³ fresh water. The vessels are also equipped with a helideck designed for a Super Puma Helicopter EC225.
