Singapore’s STX OSV Holdings (STX OSV) has confirmed an order for two platform supply vessels (PSVs) from Island Offshore.
Each of the 3,800dwt vessels will have a length of 84.3m, a beam of 17m and will be based on Rolls Royce’s UT 717 CD design.
The two vessels are expected to be delivered in the third and fourth quarter of 2013, respectively.
The contracts were originally signed on 30 October 2011 for four PSVs with a combined value of NOK1bn ($177.38m).
The remaining two similar vessel contracts are likely to become effective in January 2012 and expected to be delivered in the first quarter of 2014.
STX OSV Braila in Romania will deliver the hulls of the vessels, which are to be delivered from STX OSV Brevik in Norway.
Earlier in 2011, the Singapore shipbuilder won a $138.19m (NOK750m) contract from Island Offshore to build two platform supply vessels (PSV), which were based on Rolls Royce’s UT 776 CD design.
