Royal IHC said it has been awarded a contract for the design,
construction and delivery of a 164m-long, 44,180kW self-propelled
cutter suction dredger (CSD) Spartacus, for DEME in Belgium.

Spartacus will be the world's first CSD powered by liquefied
natural gas (LNG), following on the order for the first
LNG-powered trailing suction hopper dredgers (TSHDs) Minerva and
Scheldt River, and the LNG-ready Bonny River, that are currently
under construction at IHC's shipyards.

"We can state that this CSD [Spartacus] is the largest and most
complex that IHC has ever built," said IHC's CEO Dave Vander
Heyde. "The combination of power, size and innovations makes it a
true challenge to build."

The concept and basic design for this mega cutter was produced
via collaboration between IHC, DEME and Vuyk Engineering
Rotterdam (a 100 percent subsidiary of IHC).

The dredger's four main diesel engines can run on LNG, marine
diesel oil (MDO) and heavy fuel oil (HFO), and the two auxiliary
engines have dual-fuel technology.

According to DEME's Head of Construction and Conversion, Jan
Gabriel, "This cutter suction dredger is going to be an important
benchmark for the industry and a huge step toward limiting the
environmental impact of our vessels."

The environmentally-friendly CSD will also have a waste heat
recovery system that converts heat from the exhaust gasses to
electrical energy. The dredge control is arranged for a one-man
operation. The vessel will have a heavy-duty cutter ladder and
can reach a dredging depth of 45m.

Vander Heyde added, "IHC's strategy, which focuses on developing
and producing high added value equipment, and integrated vessels
is starting to pay off. Being able to manage all the gigantic
forces of this CSD with our high tech equipment and systems
perfectly supports this."
