TSHD Scelveringhe

General

The Scelveringhe trailer-suction hopper dredger was built in 2004 and has the largest capacity of the fleet.

By using spud poles, mooring actions are minimised. The dry unloading installation, developed out of years of experience, can be unloaded in an average of just 2.5 hours. The ship is also equipped for extraction of gravel, which can be screened with the aid of a dedicated screening plant.

The motivation of the company and dedication of the highly professional crew assure clients that the ship’s maintenance is exceptional. With a full inventory spare parts, tools, and expert well-trained hands aboard, preventive maintenance is routine and most repairs are quickly carried out by the crew.
