CABLE INSTALLATION


This would allow power cable owners to see a reduction in their repair costs, while telecoms cable owners would secure enhanced tonnage with the benefit of DP2 becoming the standard. This enhancement would allow for easier servicing of existing telecoms cables where they are in close proximity to offshore renewables infrastructure.


POWER CABLE REPAIR


COSTS ARE FREQUENTLY IN THE MULTIPLE OF MILLIONS


PRODUCT DIFFERENCES


Of course, there are some inherent differences in the products used and procedures deployed between maintenance contracts for telecoms and power cables. For a start, power cables are around five times larger in diameter


and 10 times heavier, which necessitates different handling equipment. They are also much more sensitive to crush (side wall pressure) when being moved and therefore require cable tensioners with moulded trackways over standard wheel pairs and cable drums traditionally used in telecoms.


INTEGRATING MARKETS


Among the telecoms vessels that can operate in both markets and already boasts an impressive record is Global Marine’s C.S. Sovereign. Global Marine is also undertaking a feasibility study to convert one of its maintenance telecoms vessels to enable it to undertake both power and telecoms repairs within the standard telecommunications mobilisation times of 24/36 hours. This, along with the provision of a readily available pool of qualified power jointers, would be a world first. Additionally, the company is looking to develop a universal (range) type joint to make connecting different power cables easier, without the need for cable jointing technology from specific manufacturers. It is estimated that there will be around


20,000km of power cable installed in northern European waters alone by 2030, which means that there are likely to be between 10 and 40 large cable repair projects in the North Sea annually by that date. Ultimately, the convergence of resources and skills will allow the offshore renewable market to maximise on the experience built from the telecoms market. In the case of Global Marine, the company’s portfolio includes an installed subsea cable base of over 300,000km, which equates to 22% of the world’s total. The company has also performed 33% of all maintenance operations on the world’s fibre optic cables. In short, there are clear cost and availability advantages in repair convergence available to both power and telecom asset owners.
