Osbit builds ‘state of the art’ cable test rigNorthumberland-based Osbit Ltd (www.osbit.com), an engineering specialist, has developed a bespoke ‘state of the art’ cable bend fatigue test rig for the Offshore Renewable Energy (ORE) Catapult; this will support the development of — and improve the performance and reliability of — sub-sea cables.

With cable-related failures accounting for up to 80% of the insurance claims relating to offshore wind projects, the rig enables the testing of offshore array and sub-sea cables to improve their efficiency and resilience; this in turn will support the development of next-generation wind farms and the associated electrical infrastructure.

The development of floating wind capacity represents an important economic opportunity for UK companies in R&D, design and manufacturing — with 4GW of installed floating wind capacity expected by 2030, representing an annual market value of £3 billion.

The development and testing of dynamic cables and connectors suitable for floating wind is crucial for the development of the sector, especially as these wind farms move further from shore and are subjected to harsher conditions.

The offshore renewable-energy sector has identified cables as a key area for technological improvement.

ORE Catapult’s facilities provide full-scale representative testing services to clients and partners, and this rig widens its cable test ability, adding to the established high-voltage and materials capabilities.

The rig was made using the electrical, mechanical and hydraulic designs of north-east firms including SWEL Engineering (Newburn), Metal Fabrication Systems (Sunnyside), Stockton Machine company (Teesside), North View Engineering (Darlington) and Durham Sheet Metal (South Shields).

Its key features include: testing up to three samples simultaneously; testing while fully submerged in seawater; and performing electrical and mechanical testing simultaneously.
