The Arab Shipbuilding and Repair Yard Co (ASRY) and Centrax have come together to develop a floating power station. Guy West, director at Centrax, says, “We identified four needs: natural disasters, hostile environments; global deregulation of the electricity industry; and growth in renewables.”
The Trent power barge is capable of 125MW – an optimal size for the markets cited, and for deployments anywhere in the world. The Trent is the most powerful aero-derivative engine in the world, and comes with the Rolls-Royce global support network.. The lifecycle of the barge itself is expected to be up to 40 years.
Centrax is strategically focused on geographic diversification, market diversification, and product diversification. Guy cites work in Nigeria, on the Niger, as a key prospective deployment.
Peter Thornton, director at ASRY, one of the largest shipbuilding and repair yards in the world, says, “The power barges are being built at a newly expanded fabrication facility in Bahrain. The long-term objective is to have an operational headquarters for the power barges.”
Palitha Jagathpriya, head of new build and project engineering at ASRY, described the power barge at launch; at 82m long, 28m breadth, and 5.9m depth – with a complement of ten persons. Palitha says, “This is a compact size for this kind of barge.”
The barge can be operated on either liquid fuel or gas. Its main equipment includes a turbine control and monitoring package, and three black-start generators. Palitha adds that a helipad has been added as an option.
The Trent, which also powers the Boeing 777 and the Airbus A380, is the most efficient gas turbine available. Jim Finley, executive vice-president at Rolls-Royce’s energy business, says, “The fundamental technology that sits in the Trent turbine provides the very highest power density in the market today, with the very highest levels of thermal efficiency.”
