Quick learner COSCO in successful shift to shipbuilding


Started as shiprepairer in 2001, COSCO Shipyard Group has horizontally expanded into shipbuilding since 2007 and has handled some of the highest profile shipbuilding projects in the country, writes Sandra Tsui.

also includes some of the company’s most popular products: its 92,500dwt, 57,000dwt, 79,500dwt bulk carriers and the multipurpose heavy-lift vessel of 30,000dwt, according to Xu Xiulong, Deputy General Manager of Technical Center, COSCO Shipyard Group Co Ltd. “The indus t r y s tandard of

latest MARPOL requirements and the standard of nitrogen oxides (NOx) emission. They also need to be able to burn marine gas oil (MGO) and equipped with oil-water separator and marine sewage treatment system etc,” said Mr Xu. On top of major conventions and


standard environmental protection requirements, shipowners assess new ship models by their deadweight capacity, cubic capacity, speed, energy consumption and eco-friendliness, said Mr Xu. The shipyard has, therefore, required design consultants to pay more attention to the maximisation of cargo capacity, control of light ship weight, engine selection and the processing of ballast water among other things. “Cubic capacity of cargo holds is


vital for bulk vessels, especially when carrying lighter cargoes such as grains.

The importance of cubic capacity is even higher than that of deadweight capacity in some cases,” said Zhang Bo,
