Keppel Singmarine Pte won contracts from Van Oord to build two Trailing Suction Hopper Dredgers (with an option for a third), the shipbuilder announced, scheduled for completion in 4Q 2020 and 2Q 2021 respectively.
Built to the standards of Bureau Veritas, Each TSHDs will have a hopper capacity of 10,500 cubic meters, and more importantly for environmental concerts, both will be equipped with dual-fuel systems capable of running on LNG.
"We are pleased to work with Keppel on these modern and environmentally-friendly dredgers which will strengthen our mid-class dredger fleet as well as our presence in the region. Last month we already launched our first LNG powered crane vessel," said Jaap de Jong, Staff Director, Ship Management Department at Van Oord. "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.
