The American Bureau of Shipping (ABS)-classed floating production storage and offloading (FPSO) unit Liza Unity has been awarded the SUSTAIN-1 notation by leading classification society ABS – the first FPSO in the world to be recipient of the notation, according to ABS.
ABS explained that the notation is based on assessing the design and construction of the unit and it must adhere to the requirements of the ABS Guide for Sustainability Notations, aligned with key elements of the environmental, social, and governance requirements outlined in the UN s’ Sustainable Development Goals.
The ABS Guide for Sustainability Notations focuses on the sustainability aspect of asset design, outfitting, and layout that can be controlled, measured, and assessed. Some of the features recognised by the SUSTAIN-1 class notation include: pollution and waste; coastal and marine ecosystems; energy efficiency and performance monitoring; low-carbon fuels; human-centred design; and asset recycling.
Matt Tremblay, ABS vice president, global offshore, said: “ABS has consistently supported industry in delivering a succession of technology firsts and leading innovation in offshore, and that continues today.
“This notation demonstrates how sustainability criteria can be used for offshore design and operations. We are proud to award the Liza Unity the first SUSTAIN-1 notation for an FPSO, which recognises the emphasis that ExxonMobil and SBM Offshore are giving to the alignment of its construction and operation with the UN’s Sustainable Development Goals”.
The FPSO started its voyage to Guyana earlier in September, having departed from Keppel shipyard in Singapore. Once it arrives at the Liza field in Guyanese waters, it will be hooked up to the seabed to proceed with the installation of umbilicals and risers, allowing the next phase of the operation to start.
The vessel was in Singapore after the topside was integrated by Keppel. It is expected to begin production in early 2022.
Designed to store around two million barrels of crude oil, the FPSO will be spread moored in water depth of about 1,600m. She is designed to produce around 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 Liza Unity FPSO design is based on the industry-leading Fast4Ward program, with a new build, multi-purpose hull combined with several standardised topsides modules. It is the second FPSO to be built for ExxonMobil’s Stabroek Block development in Guyana.
Olivier Icyk, managing director floating production solutions, said: “We are pleased to see that the Liza Unity FPSO is ready for the next phase and we look forward to cooperating closely with our client ExxonMobil to ensure that the start-up is a success.
“We are also very proud to see Liza Unity obtaining the SUSTAIN-1 class notation, the world’s first FPSO to do so. At SBM Offshore, we work closely with our clients and our supply chain towards the goal of reducing emissions from our products. This is an important step in our journey to deliver safe, sustainable, and affordable energy from the oceans”.
