Dual-fuel hybrid propulsion system

To maximise sustainability, the TEXELSTROOM is equipped with a dual-fuel hybrid propulsion system. Two of the four generators run on compressed natural gas (CNG) which minimize the emission of NOx, SOx and fine particles (soot). Further to that, the emission of the green-house gas CO2 is reduced significantly. The generated electricity, which is required for the propulsion by the azimuth thrusters, will be buffered in two large battery banks. This enables the TEXELSTROOM to run in normal conditions on just one generator, while the batteries provide additional power during acceleration from the harbour. The generator provides a constant power at optimal load which makes the engine very efficient.

Car capacity increase by the T-shaped section

To comply with the request to increase the car capacity, the TEXELSTROOM is increased in beam on the upper car deck level. This enables the ship to carry 14% more cars on 2 additional lanes on the upper car deck. At the lower car deck, the ship has its original beam to fit in the existing berths. As a result of the increase beam, also the saloon situated above the upper car deck, has additional space for the passengers.

Thermal water buffer tank

During the day, the cooling water of the generator(s) is heating a thermal water buffer tank. This buffer tank of about 80 cubic meters is filled with fresh water, which is heated by a heat exchanger from the engines. During the night, when this TEXELSTROOM is off duty, the ships saloon and public spaces are heated by the hot water from the buffer tank. This solution saves fuel on a boiler which would normally heat the ship during the night.

Wind drag reduction

C-Job executed Computational Fluid Dynamic (CFD) calculations on the TEXELSTROOM to lower the drag on the vessel. For this purpose, the outer corners at the ships ends, in way of the car and bicycle decks are chamfered. Also the wheelhouse is lowered compared to the DOKTER WAGEMAKER. By streamlining the vessel above the waterline, fuel consumption is lowered.

Hull form optimization

CFD calculation and tank tests have been performed on the hull to optimize the shape for hydrodynamic resistance. As a result, the fuel consumption is lowered.

Car deck ventilation

CFD analyses have been performed to improve the flow of air on the car decks. This study was done to avoid dead zones on the car deck where toxic gasses may collect and to improve the efficiency of the fans is improved and fuel is saved.

Solar panels

The upper deck is equipped with solar panels to generate as much as possible renewable energy.
