KENC Engineering has been awarded a contract to design a Hydrosound Damper Deployment System. To install monopiles at an offshore wind farm, the clients’ heavy lift vessel will be equipped with a hydrosound damper system to minimize underwater piling noise. KENC will design the HSDDS to enable a safe and quick deployment cycle of the hydrosound damper system. The project is well underway and the client - a Dutch offshore wind contractor - stated KENC showed a solid performance. Eric Buining, managing director at KENC said: “The challenge here was to develop an HSDDS in such a way that it can be fitted into the existing monopile handling system gripper design with a minimum of interfaces and within a very short timeframe. We’re very proud to contribute to the construction of the offshore wind farm and look forward to bring the project to a successful end!”.
Flood alleviation project In the UK, BMT has been awarded a project by Essex County Council (ECC) to assist with the development of flood alleviation measures from surface water flooding within three Critical Drainage Areas (CDA) identified by BMT within the County. Using the advanced modelling functionality from BMT’s proprietary TUFLOW technology, BMT will provide critical information to be used in support of flood alleviation measures for each impacted area within Essex. This will include appraisal, hydraulic modelling of a preferred mitigation, economic assessment of the preferred mitigation and a Partnership Funding Calculator (PFC) to assess the FDGiA funding potential associated with each area. BMT’s environmental consultancy business has invested in developing long term relationships with its customers and has a long history of collaboration and partnering with Essex County Council on sustainability issues and flood modelling work.

STANDARDISATION CALL

For floating wind technology to meaningfully contribute to the renewable energy mix in the next decade there must be a significant standardisation effort around substructure technologies. This is according to clean energy consultancy K2 Management, which has forecast an increase in both partnerships and OEM acquisitions as investors look to secure supply chain confidence. Will Sheard, director of analysis and due diligence at K2 Management, said: To boost broader investor confidence in the sector, funding and consolidation will be critical.” Sheard believes that in order to move beyond the R&D phase and into full-scale commercial deployment, floating wind
technology, and with it the supply chain, must be consolidated as per conventional offshore foundations previously. He explained in more detail: “The big OEMs are cautious about taking on R&D risk...but this attitude is forcing the risk and R&D pressure elsewhere - and now we have as many base concepts as we do base OEMs. “Base OEMs are typically smaller businesses without the balance sheet to drive convergence of design and therefore commercial scalability. In order to achieve floating wind at the required scale, however, investors need confidence in the supply chain - and there are potential procurement risks in having such a disparity of options available from highly specialised firms.”
Prysmian Group has been awarded a contract worth a total of around €140 million by the Turkish utility TEIAS for the design, supply, installation and commissioning of two highvoltage submarine power cable links, one between Europe and Asia, the other across the Izmit Gulf in Asia. The first project — Dardanelles III — includes the design, supply, installation and commissioning of the third high-voltage submarine power cable link between Europe and
CABLE CONTRACT Asia across the Dardanelles strait in Turkey. The cable link comprises a double circuit with a rating of 1,000MW for each circuit and extends over a total route of 4.2km (4 km submarine and 0.2 km on land). The second project — Izmit Gulf Crossing — includes the design, supply, installation and commissioning of a high-voltage submarine power cable link that will be installed nearby the

Sheard continued: “As such, there must be an increase in both OEM acquisitions and technology partnerships. To secure the future of floating wind in the next decade, we expect to see an increase in larger players including many from the diversified O&G industry with experience working with floating substructures - acquiring smaller base manufacturers, therefore providing the balance sheet backing that will support the transition to commercial scale. This will make R&D conversations between turbine manufacturers and base manufacturers equitable, and accelerate development of complete, connected, commercially viable floating wind structures.”
Osman Gazi Bridge, in the Izmit Gulf, Turkey. The cable link comprises a double circuit with a rating of 1,000MW for each circuit and covers a total route of 14 km (4km submarine and 10km on land). The official contract signing ceremony is expected within June, followed by an immediate notice to proceed. The completion of both contracts is expected by 2023.
