INTER-ARRAY CABLES


FEATURE SPONSOR


GOOD PRACTICE


The global offshore renewable energy sector continues to experience rapid development. There is clearly an increased drive within this sector to reduce costs by refining whole project design and developing new, lower cost alternatives. The importance given to the ‘Whole Project’ approach as opposed to the ‘Package’ approach should not be underestimated.


GOOD PRACTICE


Of course the success of any venture is directly related to the skill set that is employed. This is particularly so when considering offshore cables.


There continue to be significant cost reduction initiatives that focus on the cabling requirements. Key players are notably interested in promoting and supporting those initiatives that look promising.


CABLE DEVELOPMENT Areas that are currently undergoing significant development include…


• Cable protection • 66kV cable development • Termination methods • Dynamic cables


• Fundamentally new cable designs • Installation equipment, vessels, techniques and dynamics


• Maintenance/repair • Standards and guidelines


All of the above points will very likely have an impact upon the technical and commercial viability and ultimate optimisation of your project. Whilst we would like to target each one individually and expand upon them, it is well beyond the space available in this editorial.


ENSURING SUCCESS


It cannot be emphasised too highly that the underlying key to ensuring that your project is a technical as well as a financial success, rests squarely with the skills that you employ. This necessarily starts at the highest level so as to be able to assemble a properly skilled and experienced project team.


It is always essential to ensure that you have a core of skilled resources. Contracting companies and personnel will undoubtedly offer many services to your project but care should be exercised to ensure that the


skills being offered to you are indeed real. A mistake at this stage can cost the project a seriously disproportionate amount.


FUTURE PROJECT CONSIDERATIONS It would be worth considering on your future projects the following key points…


• Due diligence on different design concepts (e.g. wet type) for higher voltage levels, particularly 66kV


• Addressing the current lack of design standardisation


• Robust methodologies for handling longer lengths


• Increased need for thorough route engineering


• Emphasis on ensuring and maintaining jointing skills


• ARM: Availability, Reliability and Maintainability


SOLID FOUNDATION


A good solid foundation is what your project needs to ensure that it is ultimately constructed in the most optimum way possible. There will most likely be many challenges encountered along the route but your team of experts should be able to negotiate them all in the most technically adept and cost effective way possible.
