Innovations

With a team of four full-time engineers, TWD strongly invests in continuous innovation in the on- and offshore construction sector. By channeling the creativity of all of TWD’s engineers and designers as well as recognizing new market challenges and trends, the team develops innovative solutions and practical services and introduces them to the market to broaden our clients’ possibilities.

This is well illustrated in developments such as the motion compensated pile gripper and the friction test set-up to further optimize seafastening designs.

For stress testing and verifying the viability of new ideas and services we use a funnel principle. This continuously visualizes the development stage and what effort is required to get it to the next level. Currently new products and services came up which prove to have a lot of market potential are pushed through the funnel. To maximize the impact on the market, cooperation with contractors, knowledge institutes and other specialists are frequently sought. Not only to further develop internal ideas, but the team also welcomes all external ideas, challenges and opportunities, where TWD’s know-how could be a valuable addition. We’ll make your challenge ours and jointly work towards an effective solution!

BLADE INSTALLATION TOOL

For the installation of offshore turbines, expensive (Jack Up) installation vessels are required to install the towers, nacelles and blades on the pre-installed foundations. For the installation of the towers and nacelles, high capacity cranes are required. However, for the installation of the blades (3 out of 5 lifts per turbine), the cranes are actually largely overqualified. TWD developed a floating installation method, working parallel to the tower and nacelle installation vessel resulting in a significant cost reduction.


MOTION COMPENSATED PILE GRIPPER

Currently the majority of foundations are installed by jack-up barges. However, most existing jack-up barges do not have sufficient jacking and crane capacities to efficiently install the XL-monopiles of future wind farms. Floating installation vessels allow higher pay-loads and crane capacities than jack-up barges. However, due to wave-induced vessel motions and strict monopile verticality tolerances, current floating solutions off limited workability. The Motion Compensated Pile Gripper, as developed by TWD and Barge Master, opens the door to these significant savings and further secures the promising future of offshore wind.

MINI JACKET

TWD developed a foundation design, consisting of 3 inclined piles connected by a truss work; called the Mini Jacket. Because individual lifts do not exceed 450t, a typical 8-10MW foundation can be effectively installed by the majority of existing installation vessels. This reduces installation costs and re-opens the foundation installation market for smaller, currently outdated vessels.

MULTIPURPOSE LIFTING TOOL

The Multipurpose Lifting Tool provides a single installation tool of monopiles and transition pieces without making any configurations. Tailored to a vessel’s maximum crane capacity it allows contractors to use the same familiar tool on different items and installation projects.

JACKET LIFTING TOOL

TWD developed a jacket lifting tool that enables you to install the next generation wind turbine jackets. The Jacket Lifting Tool is currently available with a SWL up to 1500 tonne, the tool can be scaled up to your maximum crane capacity in case an increased SWL is required.

FRICTION TEST SET-UP

Uncertainty about the magnitude of friction increases the risk of undesired motions and accidents. Friction is often used in transport of heavy cargo. TWD developed a friction test set-up and is able to simulate your project specific conditions. The combination of our measurement services and our engineering provides the smartest, most reliable and cost-effective solutions for your design problems.
