UK-based engineering transport specialist Harlyn Solutions completed the secure transportation and storage of two spare inter array cables (IAC) for the Moray West Offshore Wind Farm, owned by Moray Offshore Windfarm (West) Ltd. The operation covered a short but technically challenging 30-mile route from Hartlepool to Blyth.
The spare cables, totaling a combined weight of 364 tonnes, were moved using Roll-on/Roll-off (RoRo) transport systems after being meticulously spooled into custom-engineered cable baskets. The heaviest cable weighed 209,090 kg, with the second measuring in at 154,993 kg. Upon arrival at the Port of Blyth, the baskets were safely offloaded, transferred to a designated storage zone, and fitted with protective covers to safeguard the cable integrity during storage.
What might seem like a routine move of industrial equipment was anything but. The operation required advanced planning, specialized equipment, and tailored engineering solutions to accommodate the sheer weight and volume of the assets while maintaining structural and transport compliance.
Bespoke Basket Engineering Tackles Size and Weight Challenges
One of the standout features of this project was the design and fabrication of the cable transport baskets. These were not off-the-shelf units but engineered specifically to fit the cable size, weight, and handling requirements, as well as conform to sea transport regulations. Harlyn worked in close coordination with Moray Offshore Windfarm (West) Ltd, refining multiple design drafts before receiving final sign-off from both the client and a third-party assessor.
The baskets needed to ensure not just safe transport, but also long-term storage stability. They were designed for compatibility with Self-Propelled Modular Transporters (SPMTs), allowing for precise on-site maneuvering and rotation of the heavy loads.
Seamless Execution Backed by Specialized Equipment
Transporting the cables safely required more than just strong baskets. The execution plan included detailed method statements for the entire operation—from spooling and securing to offloading and storage. The equipment roster featured a Bow Cable Engine (BCE) for loading and transpooling, SPMTs for movement on land, and purpose-built supports to prevent structural stress during storage.
Coordination with both Hartlepool and Blyth port authorities ensured compliance with all marine and land transport regulations. Timing was key to minimize disruption to port traffic and maintain alignment with the broader offshore wind construction timeline.
Real-Time Safety Culture in Action
Throughout the project, Harlyn prioritized safety. The company deployed a digital safety culture tool, accessible via QR codes placed at strategic site locations. This system allowed for real-time hazard reporting, fostering immediate response and a culture of shared safety ownership among the crew. The result: a smooth operation completed without any safety incidents.
Industry Recognition for Professionalism Under Pressure
Neil Crawford, IAC Package Manager for Moray Offshore Windfarm (West) Ltd, credited Harlyn with “technical expertise in handling our complex cable storage and transportation requirements,” noting the company’s responsiveness in addressing last-minute challenges. Crawford described the delivery as a “solid turnkey solution,” praising the team’s professionalism and methodical approach.
As the UK accelerates its offshore wind deployment, logistics operations like these form a critical backbone for project resilience and asset readiness. Spare IACs, though not immediately deployed, must be kept in prime condition for potential emergency replacements—making secure transport and storage essential for grid reliability.
Harlyn Solutions continues to expand its footprint in offshore cable logistics, offering full-scope project support from concept development and engineering through to execution. Their basket engineering and end-to-end cable handling services remain integral to the growing demands of the offshore renewable sector.
