Sembcorp Marine has entered a $1bn engineering and construction deal with Heerema Offshore Services for construction of a new DP3 semi-submersible crane vessel (NSCV).

The NSCV will be built at the Sembcorp Marine Tuas Boulevard Yard in Singapore and will be delivered in the fourth quarter of 2018.

The NSCV is expected to be the largest dual-fuel semi-submersible crane vessel in the world and will feature two Huisman heavy-lifting offshore cranes having 10,000mt lifting capacity, and will include a large reinforced work deck area.

It will also have a width of 102m, a length of 220m, and displacement of 273,700mt.

"We strongly believe in the successful cooperation between Sembcorp Marine and Heerema to build the world’s largest semi-submersible crane vessel."

Sembcorp Marine said that Tuas Boulevard Yard is designed to provide maximise operational synergy and production efficiency where the vessel will be built.

The yard is spread across 34.5ha and will include another three dry docks, a steel fabrication facility and, along with an offshore dock measuring 255m by 110m.

Sembcorp Marine Rigs and Floaters head William Gu Wei Guang said: "With our new facilities at Tuas that boost deeper quayside draft and wider dock space, we are confident that we will be able to meet our customer’s expectations.

"This is also in alignment with our strategic vision to penetrate into the deepwater draft market segment and also serves as a great testimony to our continuous commitment in providing one-stop, tailor-made solutions to our customers."

Heerema Marine Contractors CEO Jan Pieter Klaver said: "We strongly believe in the successful cooperation between Sembcorp Marine and Heerema to build the world’s largest semi-submersible crane vessel.

"The new vessel’s two tub-mounted cranes and dual fuel engines will enable Heerema Marine Contractors to offer unparalleled installation and decommissioning services.

"This will meet our long-term strategy of delivering the best possible services to the global offshore oil and gas industry."
