Keppel Offshore & Marine’s (Keppel O&M) wholly-owned subsidiary Keppel Singmarine Pte Ltd (Keppel Singmarine) has secured contracts from Dutch dredging contractor Van Oord to build two high-specification Trailing Suction Hopper Dredgers (TSHDs). Built to the requirements of classification society, Bureau Veritas, the two dredgers will be equipped with dual-fuel systems capable of running on Liquefied Natural Gas (LNG).
The new hoppers will replace existing vessels and fit in with Van Oord’s aim of making its fleet more economical and energy efficient. Each one has a hopper capacity of approximately 10,500 m3 and measures 138 metres in length and 28 metres across the beam. The vessels will be equipped with one suction pipe with submerged e-driven dredge pump, two shore discharge dredge pumps, five bottom doors, and a total installed power of 14,500 kW. They will have accommodation for 22 persons.
Van Oord has designed the Tier III vessels (IMO emission standards) in-house in cooperation with DEKC Maritime from the Netherlands.
The value of the contracts entered into by Keppel Singmarine with Van Oord is approximately S$212 million (USD 158M), excluding owner furnished equipment. They are expected to be completed in 4Q 2020 and 2Q 2021 respectively.
As part of the contracts, Van Oord has been offered an option to order a third dredger of similar specifications to the first two. The price of the option vessel will be subject to adjustments and would only be finalized and determined at the relevant time if and when the option is exercised.
Mr Jaap de Jong, Staff Director, Ship Management Department at Van Oord, said, “The TSHDs will be the first LNG hopper dredgers in our fleet. We look forward to this partnership with Keppel as we adopt LNG as a marine fuel to reduce our global carbon footprint.”
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.
