Singapore’s STX OSV Holdings (STX OSV) has won a NOK500m ($87m) contract from Island Offshore to build an advanced subsea support vessel.

The vessel will be built on Rolls Royce’s UT 737 CD design and have an overall length of 96m and a beam of 21m.

STX OSV Braila in Romania will deliver hull of the vessel, which will be equipped with one 125 tonne offshore crane and ROV systems for operations up to 3,000m deep.

Scheduled to be delivered in the first quarter of 2014 from STX OSV Brevik in Norway, the ship will be designed with a moon pool, capable of accommodating 60 persons and will be built according to Nofo standards for oil spill response.

Island Offshore is a provider of services to the offshore industry ranging from platform supply and anchor handling to advanced subsea operations including increased oil recovery (IOR) and light well intervention (LWI).

In November last year, the company had 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 were 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), while 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 along with its subsidiaries, designs and builds of offshore and specialised vessels used in the offshore oil and gas exploration and production and oil services industries.
