Offshore Ship Designers UK division OSD-IMT will supply the design for a modified version of its IMT 982 Platform Supply Vessel (PSV) to be built at the new shipyard facility of Honghua Offshore Oil & Gas Equipment in Jiangsu, China. In addition, Swire Pacific Offshore (SPO) has ordered six high-specification IMT 984 3700 DWT PSVs designed by OSD-IMT with Universal Shipbuilding Corporation (USC) in Japan, with options for a further four vessels.

The first contract is the result of increased marketing and technical collaboration between OSD group companies. It is contracted through OSD-Shanghai, with OSD-Singapore providing design engineering technical support to OSD Shanghai for design modification. The basic class-approved design documentation and design licence is provided by OSD-IMT Ltd, Montrose, UK.
