Liza Unity earns notation for sustainability

The Liza Unity Floating Production Storage and Offloading (FPSO), which has begun its voyage to Guyana from Singapore, has been awarded a SUSTAIN1 notation by the American Bureau of Shipping (ABS). According to a statement from SBM Offshore, the Dutch firm contracted by Exxonmobil and its partners to build the FPSO, the notation means that the design and construction of the unit is assessed against and adheres to the requirements of the ABS Guide for Sustainability Notations, aligned with the applicable UN Sustainable Development Goals. “The Liza Unity is the world’s first FPSO to achieve such recognition for sustainability for its design, documentation and operational procedures. Examples of features recognized by the SUSTAIN-1 class notation include energy efficiency management, mitigation of ozone depleting substances and management of hazardous materials throughout the life cycle,” it explained.

The FPSO is expected to arrive in Guyana late this year. Following its arrival at the Liza field in the offshore Stabroek block, the FPSO will be hooked up to the seabed, which will then be followed by installation of umbilicals and risers, allowing the next phase of operations to start.

The Liza Unity FPSO is designed to produce approximately 220,000 barrels of oil per day, to 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. There are total of 19 topsides modules.

The project continues to target first oil in 2022, in line with ExxonMobil’s schedule.
