TSHD Sanderus Passes Sea Trials, Ortelius Hits the Water
Jan De Nul said in its latest announcement that their 6.000m³ trailing suction hopper dredger (TSHD) Sanderus has successfully passed the sea trials.
This green vessel – Jan De Nul’s fourth Ultra-Low Emission – is the first of two identical medium-sized hopper dredgers under construction at Keppel O&M’s shipyard in Singapore, fitted with a two-stage filtering technique for exhaust gases.
The other vessel, TSHD Ortelius, was also launched at the shipyard recently, Jan De Nul reports.
The design of the Sanderus combines a shallow draught with high maneuverability, making her very suitable for working in confined areas.
The TSHD, built at the Keppel Offshore & Marine shipyard, is diesel-electric driven; all major drives (thrusters, dredge pump, jet pumps, etc) are electrically driven, and controlled by means of frequency converters.
