DOT

Delft Offshore Turbine (DOT) is a spin-out from TU Delft focused on bringing innovative offshore wind technologies to market. As a small start-up company, DOT serves as the innovation powerhouse within GROW, supporting and initiating pioneering R&D and demonstration projects, both onshore and offshore.

DOT's core technology is a seawater-pumping wind turbine. By replacing the conventional generator with a pump, the system reduces turbine weight by up to 50%. The resulting high-pressure seawater can be converted into electricity, fresh drinking water, or used to produce hydrogen through the combination of both processes. DOT has played a leading role in the offshore deployment of Slip Joint technology, including its application as an MP-TP connection, a tower-to-nacelle connection, SkyBox (developed in partnership with SIF), and as a sea-fastening solution. In addition, DOT actively supports projects such as GDP, Green-SOCCS and HypeST.

More recently, DOT expanded its innovation portfolio with PHYNIX, a hydrogen platform aimed at accelerating the integration of offshore renewable energy and hydrogen production technologies, further contributing to the energy transition. In collaboration with DOB Academy, DOT launched the Schoolbus, bringing offshore and renewable energy education to schools, industry events across the Netherlands to inspire young people to pursue technical careers and support the energy transition.

For more than ten years, DOT has continued to deliver on its promise through a dedicated team based in Delft and an international network of partners across the Netherlands, Japan, Canada, Jordan and Namibia: Positive Displacement.

Tree Composites

Tree Composites enables jacket foundations to be produced faster and at lower cost, helping make jacket manufacturing competitive in Europe again. By replacing complex welded connections with composite joints, jackets can use up to 50% less steel and become significantly simpler and faster to manufacture, while superior fatigue performance supports longer structural lifetimes. Shorter jacket fabrication can also contribute to earlier first power, creating significant value for offshore wind developers.

Developed with TU Delft, the technology is particularly suited for onsite application at fabrication yards, replacing fatigue-critical welded nodes with cost-effective composite connections applied from the outside. This enables a simpler point-to-point fabrication approach, with fewer fabrication steps, less complex welding and higher production throughput. The technology has been developed and tested through a structured certification roadmap within the GROW WrapNode-I and WrapNode-II programmes. Together with Smulders-HSM, Tree Composites fabricated the world’s first jacket using composite joints, which subsequently passed testing at 150% of its design load and a fatigue equivalent of 35 years of offshore operation without degradation.

Tree Composites is now developing automated manufacturing technology and preparing its supply chain for wind-farm-scale deployment through the €9 million Horizon Europe JOIN2SCALE programme. Embedded fibre-optic monitoring provides structural integrity data throughout operation, supporting inspection, life extension and future reuse decisions.
