For the construction of the foundations for the Hailong offshore wind farm, CWP (Century Wind Power) needed cable and pipe penetration seals that were corrosion-resistant and built to last in harsh marine environments. The transits must also to be flexible to allow for future upgrades with unknown cable sizes. After close technical discussions, CWP knew that Roxtec was the best choice.
One important reason for choosing Roxtec seals was time efficiency. With Roxtec, CWP reduced installation time by around 50% compared to conventional methods, which contributed to lower installation cost and improved productivity. Another reason was the complete technical support:
“Roxtec’s full support was great, from technical support to after-sales service and material delivery. The precision of the product exceeded our initial expectations. The installation training and logistics coordination were very well managed. Roxtec proved to be a complete solution provider for our offshore wind structures,” says Max Huang of CWP.
Careful preparations for safety and reliability
CWP needed a solution to define mixed cable layouts already in the design phase and a seal that could meet the requirements for high durability, flexibility and corrosion resistance. Roxtec started by working with them to verify suitability of material grading and recommending a suitable duplex material. Then Roxtec counter-checked technical specifications, rechecked the design together with the wind farm operator and prepared for delivery of customized sealing configurations. In addition to technical consulting during the design phase and strong logistics coordination, Roxtec provided installation and technical support to ensure correct use of the precision-engineered transits.
Flexibility for optimized simplicity and scalability
Roxtec round and oval seals are used for control cables, power cables and a temporary generator cable as well as for water drainage piping in the foundations. The transits accommodate mixed cable types and sizes and handle entries for both single and multiple cables. The main challenge to overcome was to achieve high precision without any need for design modification during installation. This helped reduce installation complexity and the risk of rework. Furthermore, Roxtec transits provide built-in spare capacity, which allows for additional cables and pipes for future expansion.
