Powerful tugs from Chinese yard
China's Zhuhai Shipbuilding Industry Company, locatedin the southern part Guangdong province is currently completing a pair of powerful tugs for Hong Kong's Big Fair Industrial Limited which acts a broker as well as a tug operator.
Last year the yard delivered a number of tugs, including a pair of 26.8 m x 8 m boats for Big Fair. Main engine towing power for these boats was a pair of Cummins KTA38 M2 engines each rated at 1,200 hp at 1,800 rpm.
The two tugs currently being fitted out for Big Fair have the same 26.8 m by 8 m hull dimensions. But they are significantly more powerful. With twin Cummins KTA50 M2 main engines. each rated at 1,600 hp at 1,800 rpm the boats will have a total 3.200 hp of main engine horsepower.
The engines turn ducted propellers through ZF Masson 6:1 gears. The boats' waterline length of 24.1 m and draft of 3.19 m on a molded depth of 3.8 m give them a maximum displacement of 435.04 tonnes.
The boats are equipped with 50-ton braking load electric over hydraulic towing winches and electro-hydraulic release towing hooks. Electrical power will be provided by a pair of Cummins 6BT5.9-powered 45 Kw generator sets.. The tugs are fitted with fire monitors and meet SOLAS FIFI requirements.
Zhuhai is a coastal city at the mouth of the Pearl River, an hour by fast ferry from Hong Kong in the east and bordering on Macao in the south. Established in 1980, it was one of the earliest Special Economic Zones in China. Zhuhai Shipbuilding carries out both repair and new construction in its floating drydocks and covered building sheds.
