Leading the way and setting the standard for offshore cable protection systems CPNL Engineering has constructively worked towards a trustworthy reputation in terms of product quality, reliability and high standards of service. The company finds itself among a highly selective group of engineers and suppliers with DNV-GL certified cable protection systems for monopiles and I-/J-tubes and installation solutions. The consistent and constructive design and development approach of CPNL has contributed to a truly diverless system with recognised reliable fit for new installations – a measured 2.5 to 3 cables per day –, as well as best retrofit in O&M installations.

A small percentage per offshore wind farm is reserved for cables and accessories. This percentage accounts for a vital part of the project; the connection to shore. If this connection is disrupted, how much power needs to be generated and distributed in order to compensate the additional – undesired – expenses?

The best approach is to avoid such situations actively, by assessing the projects accurately and by providing adequate mechanical cable protection. CPNL Engineering is proud to be an innovative engineer and supplier with DNV-GL certified cable protection systems for both monopile entry and I-/Jtubes. The systems are based on the coreproduct articulated pipe. This product has been successfully used for decades and
with the redesign of CPNL, it is upgraded to a flexible and robust system. The exclusion of fasteners explains it all. Therefore, CPNL is the only supplier that can create a unique flexible quadrant to deploy the cable with protection system in a highly controlled way over the shoot. Furthermore, the reliable fit and retrofit of the system in existing and new projects have been reviewed as the best available by customers. The straight forward approach of CPNL is to let the numbers tell the tale. More specifically, the products have been tested by independent test facilities and these results were used as input for further calculation and Orkaflex simulation. The end results were reviewed by DNV-GL and this resulted in DNV-GL certification for the bellmouths,
centralisers, articulated pipe (coated and uncoated), end clamps and spreader beam with compressed air release. The match between theory and practice is considered of vital importance. Therefore, the diverless concept of CPNL Engineering covers the range of installation and O&M. A ROV can retrieve the cable protection and a crane takes over this activity to pull the cable onboard for dissembly and reassembly of the components. The same counts for the flexible quadrant. It saves deck space and allows optimal use of this space for storage and other purposes. Smaller vessels could perform the same activities as a larger one, as it is not limited by the demand of a cable protection system. That leads to the reason why more and more customers contact CPNL.
