J-tube inspection

J-tubes guide export power cables from wind turbines to the seabed. An essential part of the wind turbine foundation structure, cables can be impeded, damaged and even blocked by excess weld penetration and internal pipe ovality. As energy regulators turn their attention towards renewable sources, more and more stringent standards are being applied with a particular focus on pipe shape and weld quality. OMS has developed a solution specifically aimed at solving these challenges in the wind energy industry.

Our award-wining weld inspection service collects real-time visual and laser data on the internal condition of your J-tubes, allowing you to:

• Achieve project specifications

• Improve asset lifetime

• Make better quality decisions

• Mitigate project risks

• Reduce costs

Inspect, repair, inspect again

OMS AGILITY robotic crawlers can access welds throughout J-tubes, including in the most difficult to reach areas, using the latest in camera and laser technology to capture comprehensive data on internal pipe condition. The inspection system assesses pipe ovality, HiLo misalignment and weld root penetration, identifying defects, areas of corrosion and obstructions. A state-of-the-art grinding system is deployed to carry out any necessary remedial work before the J-tube is inspected again and weld quality confirmed.
