CABLE PROTECTION
CABLE PROTECTION SYSTEMS AND THEIR IMPORTANCE FOR OFFSHORE INSTALLATIONS
Cable Protection systems may only be a small portion of the CAPEX of an Offshore Wind Farm. However, it provides a critical element in ensuring the reliability of all important cable which transmits the generated power back to land.
BPP CABLES AND TEKMAR COLLABORATION BPP Cables have supported Tekmar, a leading manufacturer of cable protection systems for a number of years, by providing reliable engineering analysis on their market-leading Teklink system. This value-adding verification provides reassurance to clients – usually developers and installation contractors – that the cable protection solution selected will provide reliable service for the expected life of the wind farm.
CONSIDERATIONS Amongst the many factors to be considered when selecting a cable protection system are the existing environment and the potential changes over time, such as scour. Vibration and the inevitable marine growth also need to be considered. It is common within a windfarm array for there to be considerable variation of operating depths and a “one-size-fits-all” product is rarely the answer.
EXPERIENCE
With an extensive track record of manufacturing and installing cable protection systems, Tekmar is ideally placed to build on their success and have an investment R&D programme lead the market in product innovation.
BPP Cables, a subsidiary of BPP-TECH, a long-established energy sector engineering consultancy, provides high quality support to cables-related engineering. This ranges from our proprietary HV dynamic cable designs, through analysis and product development, to forensic analysis. Through the close working relationship between BPP Cables and Tekmar the team understands the technical requirements of the developers and full range of challenges new projects serve up.
COMBINED STRENGTHS The cooperation draws from the combined strengths to deliver a well-designed, quality manufactured and executed CPS – is of greater value than the sum of the parts.
Clients are better informed of the challenges that cables face when installed offshore and the value of well designed cable protection systems. This often means cable protection engineers are engaged at an early stage to address the specific areas of risk.
Through strong collaboration, BPP Cables and Tekmar are well placed to address the major industry concerns, with practical engineering analysis e.g. cable vibration in a monopile. This pioneering analysis by BPP Cables almost two years ago enabled specific vibration studies for a number of clients, all of whom have benefited from the results – based upon very robust methodologies – which BPP Cables delivered.

JOINED-UP THINKING The offshore wind supply chain is still relatively immature but by working closer, with joined-up thinking, will assist in reducing costs and the industry becoming more competitive. The criticality of cables and their integrity has often been underestimated, but recently there appears to be a growing desire to engineer out-risk at an early stage in the life cycle of projects.
