China Harbour-Costain to Design Breakwater for LNG terminal
01 Jan 2005
In early January, China Harbour-Costain announced that it had been awarded a US$170 million contract by Sempra LNG 's Energia Costa Azul to design and construct the breakwater for a liquefied natural gas (LNG) terminal at Baja California in Mexico. The 600m break water will serve to protect the receipt terminal's LNG off-loading jetty.
Lasting 35 months, construction of the breakwater will involve towing pre-cast concrete caissons which will then be sunk to sit on a prepared granular bed. In all, there will be 16 caissons, each being 36m in length, 26m high and weighing about 9,000 tonnes. There will also be 14,140 pre-cast concrete armour blocks weighing up to 43 tonnes each, with rock/granular material of some 930,000 tonnes. At the peak of construction 800-1,000 workers could be on site. The hiring of local, qualified workers will be a priority.
Shortly before the contract was awarded, Costain chief executive Stuart Doughty and China Harbour Engineering Company (Group) president Dr Liu Huai Yuan signed an agreement setting out details of the two organisations' cooperation. The three-day visit by a delegation from the China Harbour Engineering Company (CHEC), which took place towards the end of 2004, followed the earlier formalisation of a global alliance between the two companies.
Under the agreement, Costain and China Harbour will identify international marine, port and gas terminal opportunities on a first refusal basis. Other strategic partners will be invited to join the group where appropriate. An alliance board meeting was held at Maidenhead, and a workshop held to develop the business plan and business case out to 2008.
