Dubai-based Drydocks World (DDW) has contracted Wärtsilä to design and supply the propulsion and other equipment for a new LNG-fuelled harbour tug.

According to Wartsila, this will be the first harbour tug in the Middle East region to operate on gas. It will be the first of a series of nine 29m long tugs 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.

Wärtsilä will provide, in addition to 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 contract additionally provides for lifecycle support. The LNGPac fuel gas handling system includes the bunkering station, the LNG tank and related process equipment, as well as the control and monitoring system.

The WST-18 thrusters are part of the Wärtsilä Steerable Thruster (WST) Compact series, designed for optimal efficiency, high hydrodynamic performance and easier maintenance. By achieving high efficiency at different power outputs, the WST Compact reduces fuel consumption, thereby further lowering the vessel's environmental footprint.

"We are happy to work with Wärtsilä to promote a green image for our harbour work. Wärtsilä is a solution provider with vast experience and expertise in gas fuel systems. The company has a strong local presence and is capable of providing the support needed," said Khamis Juma Buamim, DDW chairman.

"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," said Ibrahim Behairy, sales director, Middle East, Wärtsilä Ship Power.
