Sembcorp Marine’s subsidiary Jurong Shipyard has secured a $385.5m order to build a semisubmersible well intervention rig for Helix Energy Solutions Group.

The rig is expected to be delivered by January 2015 and will be built based on Bassoe Technology’s naval architectural design with Helix’s equipment layout.

Don Lee, Jurong Shipyard’s offshore division senior general manager, said: "This rig is Jurong Shipyard’s first specialised platform with well intervention and subsea capabilities and represents a significant advance for us in this growing new market segment."

"We are committed to build on this new partnership with Helix and to meet their stringent standards of quality, safety and reliability."

The new unit will be able to carry out conventional and extended top hold drilling, subsea construction, decommissioning well intervention, coiled tubing operations and twin ROV deployment.

It will have the capability to operate in deepwater operations worldwide, including the Gulf of Mexico, off the coast of Brazil and West of Africa.
