DMC steers dual-fuelled TSHDs

The 138m vessels will have a hopper capacity of 10,500m³ and each vessel will have two Van der Velden COMMANDER piston-type steering systems and two Van der Velden MASTER Rudders with fish-tail design bulb.

“The robust design and manufacturing ensures uninterrupted operation despite the harsh environment where it operates,” explained Mr Bogdan MOCANU area sales manager at DMC. “The rudder profile has been optimised during model tests for best manoeuvring performance at low speed and shallow water,” he added.

The COMMANDER piston-type is available in a range of options with regard to rudder stock connections, rudder angles and cylinders whilst the MASTER Rudder has a specifically designed fish tail profile that can be optimised to suit a wide range of vessels.

The rudders for Van Oord’s TSHDs will have an area of approximately 14m², be class approved by Bureau Veritas for speeds of up to 15 knots and generate a torque of 270kNm. With rudder angles of up to 65˚, the absence of movable parts makes the rudders ideal for vessels operating in shallow waters.
