Monopile installation complete at Inch Cape — powered by record performance from IQIP

News published on June 11, 2026

A major milestone reached at the Inch Cape Offshore Wind Farm: all 54 monopile foundations have been successfully installed in the North Sea off the Scottish coast.

Owned by ESB and Red Rock Renewables in a 50/50 joint venture, and executed by Jan De Nul using the heavy lift vessel Les Alizés, this project pushes the boundaries of offshore wind installation.

The scale of these monopiles is truly leading-edge. With diameters up to 11.5 metres, lengths reaching 102 metres, and weights of around 2,300 tonnes, these are among the largest ever installed for an offshore wind farm. Delivering this milestone required overcoming significant technical challenges.

World’s most powerful hammer range

IQIP is proud to have contributed to this achievement. The monopile installation was enabled by our Hydrohammer® IQ6, part of the IQ-series — the world’s most powerful hammer range. During installation, the hammer operated at record capacity, pushing booster mode performance to achieve final penetration under challenging soil conditions.

The IQ6 featured IQIP’s hammer interface socket, ensuring seamless connection with the CLT1700 (Combi Lifting Tool) — a combination that demonstrates efficiency and safety in every lift.

FPUT3500: ready for the future of lifting XL monopiles

In addition, this project marked the first deployment of IQIP’s FPUT3500 (Flanged Pile Upending Tool), now available in our rental fleet. Monopiles are transported horizontally and must be upended before installation. The FPUT3500 is specifically engineered for this critical operation: it engages with the L-shaped flange geometry and locks into the top of the monopile via remote control. The crane then lifts the pile into a vertical position, after which the tool disengages remotely and returns to deck — ensuring a safe, efficient, and fully “no hands on deck” operation. With a lifting capacity of up to 3,500 tonnes, the FPUT3500 is built to support the next generation of XL monopiles in offshore wind.

A strong example of collaboration, innovation, and execution at scale — and a step forward in powering the energy transition. Congratulations to Inch Cape and Jan De Nul on reaching this milestone.
