Jan De Nul invests in another high-capacity rock installation vessel

The new vessel, George W Goethals, will have a capacity of up to 37,000 tonnes and will have a flexible vertical fallpipe and an inclined fallpipe and will be able to install extra-large rock to water depths of up to 400 m.

George W Goethals will be the third rock installation vessel in the company’s fleet to have a capacity of in excess of 30,000 tonnes. It has been designed entirely in-house.

The vessel will be an ‘ultra-low emission vessel (ULEv)’ with an advanced dual exhaust filter system which removes up to 99% of particles from emissions, using a diesel particulate filter and a selective catalytic reduction system for nitrogen oxide (NOx). The system also significantly reduces exhaust gas pollutants. This technology will enable the vessel to comply with European Stage V emission standards. NOx emissions will be reduced to such an extent that this vessel meets the even stricter EURO VI emission limits.

The engines on the newbuild will be able to run on biofuel and green methanol, which significantly reduces CO2 emissions. The hybrid powerplant will also help reduce CO2 emissions and optimise fuel consumption, and will combines the use of generators with a battery and drive technology designed for peak shaving, load smoothening, spinning reserve and optimized engine loading.

The vessel will be equipped with four electrically-powered excavators. Among other applications, they will be used to load rock, enabling efficient operations without the need for a dedicated conveyor belt or crane on shore.
