Daewoo Shipbuilding & Marine Engineering (DSME) has won a $500m order to build two subsea pipe-laying support vessels from a joint venture between Brazil’s Odebrecht and France’s Technip.

The South Korean shipbuilder said that the pipe-laying vessels will be built at its Okpo yard.

The vessels, which will have a length of 146m, breadth of 30m and are capable of operating at a water depth of 2,500m, are scheduled to be delivered by August 2014.

In addition, the joint venture has been awarded a $1bn contract from Brazil’s state-run oil company Petrobras for the five-year charter and operation of two pipeline installation vessels with an option to extend this for a further five years.

The pipe-laying vessels have a high pipelay tension capacity of 550t and will be employed mainly to install umbilical and flexible flowlines and risers to connect subsea wells to floating production units in waters up to over 2,500m deep off the shore of Brazil, including in the pre-salt area.

Technip and Odebrecht have also formed a joint venture project team that will manage the construction of the vessels at the Daewoo Shipbuilding and Marine Engineering shipyard in South Korea, where Odebrecht is currently building its third and fourth of four drilling units.

The vessel operations and the provision of marine management and engineering services during the charter phase will be handled by the joint venture in Rio de Janeiro.
