Spooling & Transporting Cable
In October 2024, Harlyn successfully stored and transported two large spare inter array cables (IAC) cables, and their related accessories for use in The Moray West Offshore Wind Firm.
We were instructed by Moray Offshore Windfarm (West) Ltd to carry out this project, which involved two main elements; the transportation scope and the storage scope.
Tasking
The challenge:
The first task was to transport the cable from Hartlepool to Blyth. To do this, we spooled the cable into baskets, and shipped
the loaded baskets from one port to the other. Once we reached the Port of Blyth, we took the baskets from the quayside to
the designated storage area.
Once there, we installed protective covers on the baskets to minimise the risk of any damage to the cable. Periodically, we will inspect
the cable to check that it remains in good condition. After a call out period, we prepared the cable for load out at the quayside.
The solution:
Designing and Engineering the Baskets
One of the most complex elements of this project was designing the baskets. They had to be engineered
bespoke for this project to accommodate the specifications of the cable, and to make sure they were fit for sea
transportation.
We worked through a number of iterations of the designs, and worked closely with the client to finalise the end
product. Once the design was approved by the client and an objective third party, we managed the fabrication
of the baskets.
Transporting the Baskets
In order to transport the baskets, we first prepared method statements for the spooling operation, and
the fastening of the baskets onto the RoRo. We also prepared the necessary paperwork including approval
from the ports, and marine and client warranties. We used a Bow Cable Engine (BCE) to load and
transpool the cable, and a SPMT to rotate the baskets during the spooling operation.
For the spooling operation itself, we contracted various suppliers, including: vessels, port services, labour,
SPMTs, cranes, and cable testing.
Compliance to the highest safety standards
Projects like this inherently carry a level of risk, and at Harlyn safety is paramount.
At every stage of this project we used a safety culture reporting tool. It’s a digital reporting app, which is
accessible through QR codes dotted around the site. Our colleagues scan the QR code to report anything
to do with safety on site or the project operations. That might be reporting a hazard on site, or praising
an example of good practice, or simply a general observation.
It helps us keep a record of safety considerations and learn lessons for the future. This practice has become
standard procedure for all sites on which Harlyn operate, and helped us successfully complete this
project safely and without delay.
Outcome
We worked closely with the client, serving as a reliable point of contact to address challenges and take on additional tasks as needed. From transportation to storage and preparation, our team ensured every phase was handled efficiently. We thoroughly enjoyed contributing to this project and were pleased to provide solutions and support throughout. The client’s satisfaction was a testament to our dedication and teamwork.
Harlyn Solutions demonstrated technical expertise in handling our complex cable storage and transportation requirements for Moray West. Their methodical approach to engineering bespoke basket designs, seamless execution of the spooling operation, and commitment to safety standards all contributed to a successful job. When faced with last-minute challenges, their team responded quickly with professionalism, ensuring project continuity. Harlyn's end to end management—from design and fabrication to transportation and storage—delivered a solid turnkey solution. We look forward to partnering with Harlyn on future Ocean Winds offshore wind developments.
Engineering-led transportation

Lifting a 170 tonne linkspan to its new facility in Liverpool
Harlyn Solutions worked with MacGregor to lift and install a linkspan at the new Isle of Man Ferry Terminal in Liverpool — completing a complex, multi-phase project spanning 30 months. From transport from Poland to final installation, our team provided flexible, responsive support and acted as a single point of contact to manage evolving challenges efficiently.

Moving two 180 tonne Fibre Optic Cables
Harlyn Solutions was appointed by Sumitomo Electric Corporation to manage the transport and handling of two fibre optic cables from Sweden to Pembrokeshire, Wales, for offshore installation. Our team developed the vessel loading solution, coordinated onshore and offshore operations, and managed the return, spooling, and transport of remaining cable and equipment — delivering a smooth, efficient end-to-end operation.

Spooling Flexible Flowlines
Harlyn Solutions developed a world-first engineering solution to supply two 14 km flexible flowlines for a subsea development project, tying back seven wells and subsea trees. Our team safely spooled the flowlines onto barge baskets, enabling the client to continue production of the next 4,500 tonnes of piping efficiently.
