The BUD project entailed the construction of a 66 kilometer, 36" gas pipeline, 63 kilometers offshore and 3 kilometers onshore underground to the treatment facilities. The offshore pipeline runs from the east coast at Beachfield (Rustville), Guayaguayare, to the 'Cassia B' platform complex. At the NGC Abyssinia facilities, 3 kilometers off Beachfield, a new sludge catcher has been developed to separate the liquid or condensate from the natural gas. The condensate is separated from water and metered. The station is also designed to control the pressure of gas, as it enters into the land gas transmission system. NGC's existing 30" and 24" gas pipelines have also been diverted to the new Abyssinia sludge catcher.
Main Contractor Stolt Offshore Services, responsible for the installation of the 63 kilometers 36" offshore gas pipeline, contracted Boskalis for the associated landfall services, consisting of dredging the shore approach trench, preparation of the landfall site, pipeline pull-in services and, upon pipeline installation, backfilling of the trench. The preparation of the landfall site, including all concrete, construction and piling works was executed with local contractors, to ensure a maximum local content level.
