Drydocks Signs Wärtsilä for Middle East’s first LNG-Fuelled Harbour Tug

| UAE, Dubai

Drydocks Port TugDrydocks World (DDW) based in Dubai, UAE, has confirmed intent stated in March this year by contracting Wärtsilä to design and supply the propulsion and other equipment for a new harbour tug that will operate on liquefied natural gas (LNG). This will be the first harbour tug in the Middle East region to operate on gas. The order was signed in November. The 29 metre long tug is the first of a series of nine such vessels to be built and operated by DDW.

The project is part of a ‘green’ initiative launched by the Dubai government, and is intended to set an example for promoting environmental sustainability throughout the region.

In all, Wärtsilä will supply the ship design, two 9-cylinder Wärtsilä 20DF dual-fuel engines, Wärtsilä Steerable Thrusters (WST), type WST-18 Compact thrusters, the automation equipment, and the Wärtsilä LNGPac system.

The LNGPac is a complete fuel gas handling system for LNG fuelled ships. It includes the bunkering station, the LNG tank and related process equipment, as well as the control and monitoring system.

“The shift towards the use of LNG fuel is building up speed across the world. We at Wärtsilä feel proud that we have been at the forefront of this movement, first through the development of dual-fuel engine technology, and then by developing a full range of integrated solutions serving the complete gas value chain. This will be the first harbour tug in the Middle East to operate on gas, which indicates the growing importance of environmental issues everywhere,” says Mr Ibrahim Behairy, Sales Director, Middle East, Wärtsilä Ship Power.

The Wärtsilä 20DF is a medium-speed dual-fuel engine that can be run on either natural gas, marine diesel oil (MDO), or heavy fuel oil (HFO). The engine can smoothly switch from gas to MDO/HFO and vice versa during operation without power interruption. The use of Wärtsilä’s dual fuel engine technology enables vessels to sail without restrictions in Sulphur Emission Control Areas (SECAs) and Nitrogen Emission Control Areas (NECAs). Natural gas is the most environmentally sound fuel today, and it fulfils current actual and known future marine emissions legislation.
