MAN engines for Boskalis dredger
MAN Energy Solutions has won a deal with Dutch dredger specialist Royal Boskalis to supply three engines plus exhaust gas cleaning systems for a new trailing suction hopper dredger (TSHD).
The 31,000 cbm TSHD is being built by Royal IHC at its Krimpen aan den IJssel yard and is expected to enter service in mid-2026.
“This entire project has special requirements in all aspects – it is absolutely a customised solution and a notable feather in our cap to have been selected as propulsion-system supplier for this unique dredger,” said Lex Nijsen, vice president marine, MAN Energy Solutions.
The diesel-electric hybrid dredger will be equipped with three MAN 49/60 engines together with a MAN Low-Pressure Selective Catalytic Reduction (LP-SCR) system.
The BV-classed main diesel engines will be capable of running on either conventional fuels such as HFO and/or MDO/MGO or on sustainable fuels such as biodiesel (HVO and/or FAME). The ‘dual-fuel’ engines will also be delivered as (green) ‘methanol-ready’.
The dredgers will have two Azipods to help operation at shallow draughts and all major drives such as thrusters and dredge pump will be controlled by frequency converters with asymmetric load-sharing for optimal efficiency.
