Seatools delivers pre-piling template equipment for Hai Long Offshore Wind Farm project

Seatools has announced the successful delivery and operation of its pre-piling template equipment to CSBC-DEME Wind Engineering (CDWE) for the Hai Long Offshore Wind Farm project. This milestone adds to Seatools’ extensive experience in advanced subsea metrology and control solutions, gained from over 12 similar pre-piling template projects.

Seatools, in close collaboration with CDWE, was responsible for the comprehensive design of the pile template’s metrology and control system, encompassing all mechanical, electrical, hydraulic and software components. The scope also included hydraulic and mechanical systems dedicated to template levelling and precise pile positioning. The advanced metrology system ensures that pile installation is achieved with exceptional accuracy, meeting stringent tolerance requirements.

“The commissioning of the equipment supplied by Seatools was notably smooth,” said Jan Frumau, managing director at Seatools. “This result was largely credited to Seatools’ utilization of advanced simulation capabilities and to the constructive collaboration with CDWE through the different phases of the template design.”

Reduced need for on-site calibration

The sophisticated simulations subjected the equipment to extensive virtual testing under various operational conditions prior to its actual deployment. This proactive approach significantly reduced the need for on-site modifications and calibration, streamlined the commissioning process and improved the certainty of adhering to the offshore wind farm’s construction schedule. The accuracy and reliability demonstrated through these simulations reflect Seatools’ dedication to employing technology for superior project performance.

The project uses both a vibratory hammer and an impact hammer for pile installation. This mixed-method approach led Seatools to undertake a detailed evaluation, ensuring the equipment’s structural integrity and operational reliability under the varied loads imposed by both the vibratory and impact methods.

“I am very pleased to have successfully delivered this pre-piling template equipment to CDWE for the Hai Long Offshore Wind Farm,” remarked Jan Frumau. “This project not only solidifies Seatools’ position as the preferred supplier of mission-critical subsea equipment for industry leaders such as CDWE, but also highlights the strength of our partnership. The excellent cooperation we experienced with CDWE was instrumental in achieving such a smooth execution. We remain dedicated to equipping them with reliable subsea technology to ensure productive, accurate and uninterrupted offshore installation operations. By leveraging our advanced simulation techniques and robust industrial-grade subsea hardware, we empower our clients to perform effective and precise pre-piling operations.”
