BOSTON -- Construction has begun on the Neptune LNG project, according Suez Energy. The first phase of construction, expected to be completed in September 2008, includes the installation of a 13-mi (21-km) subsea pipeline that will connect the Neptune LNG facility with the existing Spectra Energy HubLineSM. The second phase, scheduled to begin in May 2009 and continue into September 2009, includes connection of the pipeline to HubLineSM and installation of two offloading buoys.
Upon completion, the LNG facility will consist of an unloading buoy system where specially designed vessels will moor, offload their natural gas, and deliver it to customers in Massachusetts and throughout New England.
Pipeline installation activities for 2008 include laying the pipeline (consisting of both a natural gas transmission line and a flowline that connects the buoys) on the sea bottom; plowing a subsea trench; placing the pipeline in the trench; and backfilling the trench.
