Durham Lifting Supports MultiSec in Launch of One of the World’s Largest C-Hooks for Offshore Wind
28th July, 2025
Durham Lifting and MultiSec are proud of the successful launch of one of the largest C-Hooks ever produced. Designed and manufactured here in Middlesbrough, this groundbreaking piece of lifting equipment has been developed to meet the demands of some of the world’s biggest offshore wind monopile sections (cans and cones).
The new C-Hook – engineered to lift monopile sections up to 4.2 metres in length, 15.5 metres in diameter, and weighing as much as 125 tonnes – will be supplied to SeAH Wind, a global leader in offshore wind energy.
Driving Innovation in Offshore Lifting
Durham Lifting and Multisec worked together to ensure the design, manufacture, and testing of the C-Hook met the strictest standards for safety and reliability. This innovative hook incorporates a dual gantry crane system with motorised counterweights, enabling full rotation both clockwise and counterclockwise – a major advancement over traditional C-Hooks that only tilt in one direction.
By integrating this unique counterweight system, the hook offers flexibility across a wide range of monopile can and cone sizes, with varying centres of gravity. Our engineering input also ensured that the mechanical load path bypasses welds, further enhancing safety, strength, and long-term durability.
Showcasing Teesside’s Engineering Strength
This achievement is not only a milestone for Durham Lifting and MultiSec but also a celebration of Teesside’s world-class engineering and manufacturing capabilities. We were pleased to welcome Middlesbrough Mayor Chris Cooke to view the hook in person, shining a spotlight on the role our region continues to play in advancing renewable energy infrastructure.
Supporting the Energy Transition
At Durham Lifting, we remain committed to supporting the global shift to clean energy by providing specialist lifting equipment, testing, and engineering expertise. Working alongside MultiSec, we continue to deliver bespoke solutions that enable safe, efficient, and sustainable offshore wind projects.
Together, we are proud to be shaping the future of heavy lifting – one project at a time.
