American petroleum company Hess Corporation said that the Liza Destiny floating, production, storage and offloading (FPSO) vessel has arrived at the closely watched Stabroek Block offshore Guyana after a 42-day journey from Singapore.

After clearing customs, hookup and installation of the Liza Destiny FPSO will begin. The Liza Phase 1 development is on track for startup by the first quarter of 2020 and will produce up to 120,000 gross barrels of oil per day.

The Stabroek Block is 6.6 million acres (26,800 square kilometers). ExxonMobil affiliate Esso Exploration and Production Guyana Limited is operator and holds 45% interest in the Stabroek Block.

Hess Guyana Exploration Ltd. holds 30% interest and CNOOC Petroleum Guyana Limited, a wholly-owned subsidiary of CNOOC Limited, holds 25% interest.
