Subsea experts swapped the wilds of the North Sea oil fields for London’s sewerage and river network as the potential for energy sector knowledge to be used in a diverse range of projects has been announced on the eve of an ocean technology event behind held in the city today.

Specialists from Aberdeen-based Neptune were mobilised to work on the Thames Tideway Tunnel development during a 20-day study last month.

When operational, the 25km tunnel will create a new sewer, urgently needed to protect the River Thames from pollution caused by sewage overflow due to insufficient capacity.

Neptune provided diver tracking services to Hughes Sub Surface Engineering, with a surveyor working on board the Thames Explorer to monitor those working on the riverbed near Blackfriars Bridge as they conducted an unexploded ordnance (UXO) survey.

The scope was carried out by Neptune and Hughes on behalf of VolkerStevin, which was awarded the contract for enabling works for the sewerage development.

Kevin Stephen, operations and business development director, said: “From our facilities in Grampian, Neptune is built on strong foundations in oil and gas, but utilising the knowledge and expertise we have within the business across a wider spectrum of applications is at the heart of ambitious plans for growth.

“Decommissioning, renewable energy, nuclear energy and a wide range of subsea opportunities are all open to us and the Thames project is a perfect example of the ability we have to diversify.

“UXO surveys are common throughout Europe, an unfortunate wartime legacy, and we are well versed in the process – from initial magnetometer surveys used to identify targets through to diver and ROV surveys as well as subsequent clearance. On this occasion our involvement was in dive support, but we are equipped to provide the full scope.”
