OKLNG (a joint venture between BG international, Shell, Chevron and NNPC) was seeking to create a new LNG export plant in a remote location within a very tight timescale. The greenfield project site straddles the borders of the states of Ogun and Ondo, approximately midway between Escravos and Lagos.
Originally, the dedicated marine facilities of the project for product loading included berths suitable for LNG and refrigerated LPG carriers, an 8 km jetty and single point mooring buoy for loading condensate. The LNG/LPG berth required protection by a breakwater.
Royal HaskoningDHV was contracted to perform the Front End Engineering and Design (FEED) for both the Marine Facilities as well as Site Preparation.
As well as design of the LNG facilities, our responsibilities included the preparation of a Breakwater Study Report, the organisation and supervision of laboratory testing of the breakwater and site inspections of quarries and other potential sources of rock for breakwater construction.
During a subsequent value engineering process, our team assisted the client in further fine-tuning and optimising the facilities to drive down costs and programme.
