Singapore-based Dyna-Mac will be working on the topside modules for the 220,000 bpd Liza Unity floating production storage and offloading vessel for ExxonMobil’s second development offshore the South American country of Guyana.

According to a report in Upstream, Dyna-Mac confirmed on Monday that it would be carrying out the fabrication of the topside modules for the Liza Unity. This comes just days after ExxonMobil announced sanctioning of the Liza Phase 2 development and SBM offshore confirmed award of the contract to construct, install, lease and operate the floater for up to two years.

According to Upstream, Dyna Mac beat off stiff competition from yards in China in order to win the repeat order from SBM for the Liza Unity topsides and the award formed part of the S$150 million (US$109.9 million) worth of contracts Dyna-Mac announced in March.

The hull for the Liza Unity is being built at Shanghai Waigaoqiao Shipbuilding in China and is based on SBM’s Fast4Ward design.

The Liza Unity will be designed to produce 220,000 barrels of oil per day, will have associated gas treatment capacity of 400 million cubic feet per day and water injection capacity of 250,000 barrels per day. The FPSO will be spread moored in water depth of about 1,600 meters and will be able to store around 2 million barrels of crude oil.

The Liza field is located in the Stabroek block approximately 200 kilometers offshore Guyana. ExxonMobil affiliate Esso Exploration and Production Guyana Ltd. is the operator and holds a 45 percent interest in the block. Hess Guyana Exploration Ltd. holds a 30 percent interest, and CNOOC Petroleum Guyana Limited holds a 25 percent interest.
