Swire has ordered eight IMT-997 platform supply vessels (PSVs), with four to be built by Universal Shipbuilding Corporation in Japan and a further four to be built by EISA Shipyard in Brazil. Each vessel will be equipped with 4 × 6L27/38 MAN gensets, with each unit rated at 1,980 kW at 720 rpm. All generating sets will be constructed by MAN Diesel & Turbo’s Korean licensee, Doosan Engine Co. Ltd.
The 97-metre, 5,000-dwt PSVs will be approved with DP2 (dynamic positioning) capability and have diesel-electric propulsion systems with azimuth propulsion units. The vessels will be delivered progressively from early 2014 on, with genset delivery accordingly timed to stretch from early 2013 through mid-2014.
