SINGAPORE (May 23): Keppel Singmarine, the subsidiary of Keppel Offshore & Marine (Keppel O&M), has won contracts from Codralux S.A., a wholly-owned subsidiary of Jan De Nul Group, to build two Trailing Suction Hopper Dredgers (TSHDs).

TSHDs are mainly used for dredging loose and soft soils such as sand, gravel, silt or clay. The dredged material can be deposited on the seabed through bottom doors or discharged through a floating pipeline to shore and used for land reclamation. The dredgers are valued at $120 million, including owner-furnished equipment.

Keppel Singmarine is currently building three dredgers for Jan De Nul Group, based on contracts that were secured in July 2016.

The first of the two dredgers for this new order is expected to be completed in 2H 2019. Construction of the second dredger will require Codralux S.A to exercise the option within six months from now.

The dredgers will comply with the International Maritime Organisation's (IMO) Tier III and European Union (EU) Stage V regulations, which set stricter limits on emissions of particulate matter. Keppel Singmarine will be the first shipyard in the world to build an EU Stage V dredger.

When completed, the two TSHDs will be able to dredge to a maximum depth of 35m and have a hopper capacity of 6,000 cubic metres. The three TSHDs currently being built by Keppel Singmarine will be able to dredge to a maximum depth of 27.6m, and have a hopper capacity of 3,500 cubic metres.

Keppel O&M is the offshore and marine arm of Keppel Corp which closed 1 cent lower at $6.55.
