Allison Companies supplied a full roster of services for the PETRONAS D21 Project, including: engineering, procurement, fabrication, transportation, installation and commissioning. The four pile jacket and deck including topside facilities was fabricated in Amelia, LA, USA and transported via material barge to location offshore Malaysia for installation.
The project’s schedule required projected first oil within a 12-month period. Typically, similar projects achieve oil within a 2- to-3 year timeline.
The Allison Companies team employed the use of a refurbished structural field deck, providing engineering and building the topside facilities and 500 ton, four pile platform jacket within the United States. The deck’s capabilities included accommodations of up to 6 wells, manifold, in addition to a test separator; a pig launcher; instrumentation and electrical which included MCC and gen sets; a chemical injection skid; a potable water system; and pedestal crane and sump. Design capacities of the topside facilities were 17 MMSCFD and 2500 BOPD.
After fabrication and on-shore precommissioning was complete, the deck, jacket and piles were transported via the Panama Canal on an ocean-bound, offshore barge in Malaysia where they were installed in water depths of 166 ft., along with approximately 13 km 10″ pipeline.
The project was concluded as incident-free, and was delivered successfully on time and on budget.
