Lowestoft Eastern Energy Facility (LEEF)

Suffolk town of Lowestoft

The Port of Lowestoft is close to one of the most significant clusters of offshore wind farms in the UK. It provides a convenient marine hub for offshore wind customers to maintain operations, repower, and construct offshore wind sites. It handles around 30,000 tonnes of cargo per year and contributes £30 million to the economy and supports 580 jobs.  As Lowestoft has established itself as a thriving centre servicing the offshore energy industry, the LEEF project forms a central part of a new masterplan further developing the port as a hub for the southern north sea energy sector.

Our Role

Associated British Ports appointed ByrneLooby as the lead engineering consultant to provide the design phase of the Lowestoft Eastern Energy Facility. This project will provide significant re-engineering of the existing quayside in the outer harbour, creating a modern port that supports the renewable energy industry. Our marine team will develop a completed concept design for the outer harbour ready for a design and build tender. The concept design is to be produced in line with the requirements of Associated British Ports and the selected preferred option.

When complete, the project will offer 360m of berthing space for simultaneous use by three SOVs and deliver up to 8 acres of flexible storage and marshalling area. In addition, it will enable the development of around 5,000 sq. ft. of new office space with direct quayside access.


This first phase in the port masterplan will help to pave the way to achieving the ports positioning as a hub for leading the delivery of the green industrial revolution in the UK.
