China's Tugboat Industry Is Experiencing A Trend Of Hybrid Power.

Building a green image and adhering to stricter environmental standards is an important trend in the Chinese market. In the area of port towing and escort, the concept of waxiland HY is the perfect choice.

In Singapore (September 2017) and China (December 2017) officially launched the exhibition of wartsila HY tug is a new type of hybrid based on the technology of wartsila HY tug, which USES mechanical engine and battery power combination to meet the needs of the job. Wartsila HY tug is especially suitable for the Chinese market, as one of the world's biggest market because of its traditional tug on the basis of improved the operation efficiency, reduce the fuel consumption and less emission, stronger performance.

Is the Chinese market ready for a hybrid tug?

In September of 2017 Shanghai international maritime technology conference and exhibition, we announced wartsila HY tug design has been certified by China classification society (CCS) approved in principle, the potential customers in China is to enhance confidence in the new hybrid technology of important steps.

"Now our focus is to work with Chinese and foreign towing builders to advance the HY technology, and in general they are very interested." "Said xu zhongwei, a sales manager of ship design in China for the Chinese market.

According to the TugTechnology & Business magazine, there are about 18,000 tugboats around the world. "But the market has about 300 new tugs per year." Xu continued. "This is a stable, sizeable niche market, and the Chinese market accounts for about 50 new tugs per year."

In principle, tugs around the world are the same. But what sets the Chinese market apart is the social and economic differences between Asia and Europe, which will be factored into future tugs.

"Compared with Europe tug (6-8), China tug crew more often (10-14), the cabin number is more, this is because the crew need to stay on board for two weeks," xu manager explains tug of China and other countries is an important design differences.

Wartsilan HY technology combines engine and accumulator energy storage systems to work through a new and optimized energy management system. HY tug are wartsila and American bureau of shipping (ABS), bureau veritas (BV), the United Kingdom Lloyd's register (LloydsRegister) close cooperation design, and has been certified by China classification society (CCS).

The design of the wartsilan HY tug offers three different hull sizes, namely the 28-meter port tug, the 29.5 m port tug and the 35 m escort tug. Using the appropriate waxylon equipment package module, the tension of 40-90 tons of mooring pile is covered. It adopts unique propulsion configuration, so that each design can choose diesel mechanical hybrid or diesel-electric hybrid propulsion.

Tugboats usually operate in the area around the port or port, especially in respect of environmental regulations. This compliance requirement is increasingly being taken seriously by port towing and escort operators. Battery technology means a lot to the tug, because it is idle for a lot of time.

"The battery can be operated with low load and zero discharge." The debate about the economics of the waxilan HY is explained by the ship's design and sales manager, shipbuilding designer Ay Hwa Ngoh. "With battery power also means that we can reduce the installed mechanical power, because the biggest bollard pull accounts for only about 1-2% of the annual average tug of assignment, and combined with the engine battery can be used to enhance power when necessary."

Cost savings from hybrid power.

In addition to achieve the same bollard pull need to significantly reduce the number of the engine, battery hybrid system cost can be saved in a number of ways, for example because of the reduced engine running hours and reduces the maintenance cost, lubricating oil and fuel consumption is reduced, and the reduction in emissions.

"We believe that China is actively applying hybrid battery technology in many areas, including tugs." Ngoh said.
