According to MAN, each engine will come accompanied by an exhaust-gas after-treatment system, namely an MAN Low-Pressure Selective Catalytic Reduction (LP-SCR) system, that ensures IMO Tier III compliance.

The newbuilding will be built at Dutch shipbuilding company Royal IHC, at its Krimpen aan den IJssel yard and is expected to enter service in mid-2026.

Also, the TSHD will be diesel-electric powered with two Azipods to allow vessel operation even at shallow draught.

All major drives (thrusters, dredge pump, etc.) will be electrically driven and controlled by frequency converters, enabling each system to operate at optimal speed and power.

The asymmetric load-sharing results in optimal load distribution over the diesel generating sets with low fuel-consumption and high maneuverability, said MAN.
