The Grand Alliance is to boost its services, with member lines due to put 18 new Post-Panamax vessels into service by the end of next year.
Orient Overseas Container Line (OOCL) has six 5,500 teu (20 ft equivalent unit) vessels starting operations between December and August next year, Hapag Lloyd will supply seven 4,800 teu vessels and P&O Nedlloyd will supply five 5,500 teu vessels.
OOCL's six 5,500-teu vessels are on order from Taiwan and South Korea shipyards. It says they will enter the key east-west trades, either Asia-Europe or Asia-United States.
The company's Asia-Pacific managing director Jim Poon said the route would be decided after talks with its partners.
The alliance groups OOCL, Hapag Lloyd, Malaysia International Shipping Corp, NYK Line and P&O Nedlloyd.
OOCL expected to benefit this year because early alliance problems had been solved, he said.
