Design Philosophy Anchorage
For Barkmeijer Shipyards we provided the naval architecture (hull design and stability calculations) of this Trailing Suction Hopper Dredger (TSHD) or Marine Aggregate Dredger (MAD). The hull shape is optimised for sailing at both loaded and unloaded draught by Computational Fluid Dynamics (CFD) calculation. The dredger was delivered on the 5th of June 2020 to the Zeeland based company De Hoop Terneuzen. This family owned company is a major supplier of building materials in Holland and Belgium.
The design brief for the dredger was rather comprehensive. Without limits to the navigation area, the design had to be able to dredge sand and gravel up to a depth of 60 metres, screening this to the required grain size and dry discharge to shore in ports with a great variety in receiving facilities. The dredger’s design is characterized by a high freeboard for operations at the high seas. No bottom doors are foreseen, as the intention of this vessel is to unload the aggregates ashore. The ship is laid out at a loaded speed of fourteen knots, which is quite fast for a dredger, in order to reduce the transfer time between the deeper concessions and the discharge ports.
The Anchorage has been developed and built in the Netherlands in collaboration with Dutch suppliers, mainly from the northern part of the Netherlands. The design and construction of the dredger was undertaken by Barkmeijer Shipyards in Stroobos, part of the Thecla Bodewes Shipyards Group.
