Executing projects safe, cost-efficient, and limiting environmental impact
At IQIP, we recognise that people, the planet, and profit are not mutually exclusive. Part of our philosophy is ‘No Hands on Deck’ because we believe the safest way to work is to have as few people involved in potentially hazardous operations as possible.
IQIP wants to achieve safer and environmentally friendlier operations, and we can do this through our products, and our continuous improvement approach. Our work is never done because once we have developed the tools, we then work on improving them, creating addons, and integrating new solutions – it’s a continuous story.
True to our philosophy of “No hand of Deck” we continue to work on our Combi Lifting Spread (CLS). By creating the CLS, we have not only reduced the crane movements by over 50% but also the workforce required for manually connecting the slings between the crane and the installation equipment. We made the whole operation safer by limiting human interference – fewer hands on deck. Together with less wear and tear, this has a direct impact on the maintenance costs of the installation equipment.
The continued work on the CLS has also led to the development of another tool that prevents the overloading of the crane, the Pile Run Crane Protection System (PRPS), which acts as an add-on to the hammer and CLS and increases the safety of the installation. Ultimately, any delays caused by injuries or damaged equipment will increase the entire cost of a project. Both the CLS and PRPS have been developed to lower the risks – not only financial but also environmental and in terms of safety – of the projects on which they are utilised.

The Lifting Connector is the main piece of the Combi Lifting Spread and is the connection between the crane and tools. This system can serve as a replacement system from a typical crane hook. One of the key design principles on the Lifting Connector is the ring of latches around its center. These can slot seamlessly into the corresponding sockets. The latches connect underneath the flange of each socket on the corresponding equipment, which creates a fail-safe lift and allows each tool to be introduced quickly as required.
The Combi Lifting Spread exists of multiple installation tools, that can be used for foundation installations. The Hydrohammer, Transition Piece Lifting Tool (TPLT), Flange Pile Upending Tool (FPUT), Upending Tool (UT) and the Integrated Monopile Installer all have interface sockets that connect easily with the Lifting Connector to serve as a replacement system from the conventional shackle and rigging connections.
When a tool of the Combi Lifting Spread is needed the Lifting Connector connects with the lifting interface socket and lifts the tool easily through the center of gravity to ensure a stable and safe lift. In this way, monopiles and transition pieces can be placed with less crane movements and vertical transits, which saves time but also reduces the wear and tear on the crane. Besides that, human intervention can be reduced while less riggers are needed during the use of the Combi Lifting Spread. In addition, the Combi Lifting Spread requires less deck space by reducing the number of shackles, lifting slings and spare parts.
The Combi Lifting Spread (CLS) - To guarantee time-efficient installation, increase the safety by reducing human interference, reduced crane movements, and the number of interfaces. Next to that Less deck space needed!

Wondering how Jan de Nul installed the foundations for the offshore wind farm Borkum Riffgrund II in Germany? Minimizing environmental impact and underwater noise by means of a special IQIP noise mitigation system and a bubble curtain. In addition, by using the Combi Lifting Spread, the installation takes less time, which is also a lot better for the environment.
Northwester 2 is the seventh offshore wind farm off the Belgian coast. Contracted by Parkwind, Jan De Nul Group were entrusted with designing, building, and installing 23 foundations, transporting and installing the cables, and installing the wind turbines on top of the foundations.
