OSD-IMT, the UK division of Netherlands-based Offshore Ship Designers (OSD), is developing two IMT 9120 Riserless Light Well Intervention (RLWI)/IMR vessels for Austin Offshore, the shipping arm of Upstream Drilling, Singapore.

The diesel-electric propulsion vessels are intended to carry out riserless light well intervention, light construction, subsea installation, inspection maintenance and repair of subsea installations.

They can deploy three ROVs, and have a 250-tonne-capacity AHC crane as well as a travelling gantry well intervention tower system. The 9,500 dwt vessels have accommodation for 140 persons. Dimensions are 120 m LOA, and 30 m beam with an operational draft of 7.5 m.

The vessels will be built by China Merchants Industry Holdings, Hong Kong, China, under a contract with Singapore-based Upstream - Austin Offshore signed at the Marintec Conference and Exhibition in Shanghai on Wednesday, December 2, 2015.
