Offshore Wind ChinaChina market will keep growing quickly in next ten years
Currently, there are in total 266 planned projects of 135.64GW
Looking ahead, China has entered a rapid construction period under the pressure of a new decreasing FIT scheme
Advanced supply chain needed to tackle the challenge of cost reduction
We are in the region early and have been influencing powerful local stakeholders

What is a Cable Protection System (CPS)?

Total Cables Package: 8% of total project CapEx
Cable Protection Systems: 3% of Cables Package
0.24% of total project CapEx
So Cable Protection Systems are a small package in terms of cost!
However in Europe cables have represented up to 80% of the cost of the insurance claims, so the Cable Protection System package is a very important one!
A single cable failure can be very expensive and could cost more than double the cost of the Cable Protection Systems for the full project, per claim:
Lost power generation revenue
String length affected
Expected repair time
Cost of new cable
Removal of old cable and installation of new cable

The Business Case

Strictly Confidential 机密
Cables will become exposed if not protected with a CPS:
Scour development
Rock Dumping
J-tube Extensions / Telescopic J-tubes
Mattressing
Exposed cables will be damaged over the service life of the windfarm to a point where they can no longer transmit power:
Over-bending/tension
Abrasion
Impact
Fatigue
Tekmar’s CPS also offers numerous other benefits such as:
Removal of j-tubes (monopile foundations)
Improved thermal ratings of power cables
Easier removal and replacement of damaged cables

Cables are high risk and need protecting.
The cost of replacing cables is high.
Tekmar’s cable protection system will reliably protect cables, as well as offer significant cost savings in reduced steel costs and optimised installation.
Designing cable protection systems is complex and requires specialist knowledge and experience.
