The Operation Delivered
Harlyn’s scope included full mobilisation management, transportation of major equipment to the quayside, vessel loading, and the engineering, fabrication, and installation of all required grillages and interface structures. The team also oversaw heavy lifts, sea fastening, deck setup, and the final load testing of the A-frame.
Key Challenges Identified
The challenge:
Multiple equipment interfaces and technical requirements
Requirement to engineer, fabricate, and install all mobilisation grillages and interface structures.
Coordination of heavy lifts, sea fastening, deck setup, and final load testing activities.
Need to reduce vessel time while maintaining high QHSE standards.
Requirement for seamless integration between Harlyn, Helix Robotics Solutions, and the vessel crew.
Complex Demands. Clear Results.
The solution:
Our project team managed transportation of major equipment to the quayside and execution of all vessel loading activities.
In house engineering team completed fabrication, and installation of mobilisation grillages and interface structures.
Site team oversaw heavy lifts, sea fastening, deck setup, and final A-frame load testing.
Executed all RAMS, lift plans, and HSE procedures to Harlyn’s rigorous QHSE protocols.
Coordinated closely with client and the vessel crew to ensure seamless integration.
Conducted off-site prefabrication to minimise vessel time and increase operational efficiency through our supply chain.
Outcome
Precise and Efficient Operation
Harlyn safely completed the full mobilisation works for the JD Assister vessel with the Helix Robotics Solutions i-Plough spread at the Port of Blyth, delivering all objectives to the highest quality standards. The project demonstrated Harlyn’s capability to execute technically demanding vessel mobilisations efficiently and in full compliance with QHSE requirements, culminating in successful load testing and handover to Helix for final commissioning. The campaign also reinforced the strong collaboration between Harlyn and Helix in supporting subsea infrastructure and offshore wind development.
This mobilisation was a great example of how strong teamwork, careful planning, and close coordination can deliver a complex project smoothly. Our team worked efficiently to manage all aspects of the operation, overcoming the usual challenges that come with this type of work. Thanks to the excellent collaboration with Helix Robotics Solutions and the vessel crew, everything was completed to a high standard and on schedule.

Bespoke Engineered Solution for Concept Subsea Noise Mitigation System
Harlyn Solutions collaborated with Pulcea Ltd to design and fabricate a bespoke support frame for Pulcea’s pioneering Subsea Noise Mitigation System—a first-of-its-kind concept tested at the ORE Catapult dock in Blyth. Through precise engineering, robust project processes, and close client collaboration, Harlyn successfully delivered all objectives on time and within budget, completing site work in just three days.

Leftover Cable Storage
Harlyn Solutions was commissioned by Sumitomo Electric Corporation to transport fibre optic cables from Sweden to Wales for installation on the Greenlink Interconnector Project — a key initiative connecting renewable energy between Ireland and Great Britain. After installation, our team also managed the safe spooling and storage of remaining cable. We’re proud to have supported this award-nominated project driving progress toward Net Zero.

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.
