CWind provided cable pulling support to CT Offshore, enabling the diver-less installation of the array cables between the 108 turbines at Dong Energy’s West of Duddon Sands offshore wind farm. CWind also provides the vessels required to undertake the work. Our teams arrived at the transition piece to be ready prior to the arrival of the installation vessel, preparing the rigging equipment for the hang-off, jointing and termination. Meanwhile, on the installation vessel a second team prepared the ROV and messenger cable, significantly reducing cost and delivery timelines for the project.
CWind provides a comprehensive package to customers. By providing both vessels and technicians in well-tuned teams, CWind can respond to the tight operating windows at West of Duddon Sands. The use of CWind’s modular vessels enabled the team to carry all the equipment needed for the task as well as the technicians that will carry out the work. By reducing the number of vessels needed on site we are able to deliver cost as well as time-savings to our client.
Despite the high tidal range of 9m at the site, CWind’s highly experienced teams of technicians, experts in handling the ROV in the currents at the site, consistently connected both ends of the array cables to neighboring two towers in under five hours.
CWind’s ROV-messenger wire method removed the need for divers at the site, significantly reducing risk levels as well as costs for the project. The speed of execution meant that the short time windows at West of Duddon Sands have a much reduced impact on the speed of construction of the wind farm.
Pulau Ketam is a small island located off the coast of Klang in Malaysia which had previously been powered by small electrical generators. The Malaysian-Kapar to Ketam power cable project, delivered for Tenaga Nasional Berhad (TNB) Malaysia’s main energy provider, connected the Kapar Power Station on the mainland to the island.
The project presented several challenges, most significantly the extent of the cable protection required resulting in a record-breaking cable burial depth to 13.8 metres below the seabed. Networker, 60 metres in length with a proven track record in Asian waters, successfully handled the simultaneous lay and burial aspect of the project.
A study commissioned by TNB that looked at future port plans for the coming years and included potential dredging requirements, highlighted the need for the cable be buried to an unprecedented depth of over 12 metres. At this depth, the cable would be fully protected throughout its life without creating any restrictions on the possible expansion of the port. In fact, the cable was buried to depths of up to 13.8 metres below the seabed. In addition to the 1.5km of cable buried at 12 metres below the seabed, 600 metres of uraduct cable protection was also installed to provide long-term protection on each side of the shipping channel.
At Gwynt Y Môr (GYM) offshore wind farm a number of the Cable entry sealing systems had been leaking resulting in fluctuating water levels inside the monopoles, which compromised the internal corrosion protection systems. A retrofit internal cathodic protection system was required to address these problems and a contractor to supply and install Impressed Current Cathodic Protection (ICCP) systems in three assets experiencing the problems. CWind, in partnership and liaison with the client (GYM) and the already appointed ICCP designer undertook detailed design of the ICCP system hardware and software and the ventilation system.
With CWind’s ability to bring extensive resource to the project, we were able to supply all equipment, hardware and software, undertaking the works required offshore to install the ICCP systems on the three assets. CWind were responsible for the installation to required quality and safety standards as well as providing any hosting, pre-processing or hardware to enable system control, and provision of all real time data for 12 months of operation.
CWind worked closely with the client, RWE, to ensure all scheduling and pre-planning works were completed prior to installation. This limited downtime and combined planning with pre-install asset inspections ensured that pre-installation works were complete before team deployments.
CWind were awarded the 20 year maintenance and emergency response contracts for both the onshore and offshore substations at Dong Energy’s Westermost Rough offshore wind farms for Transmission Investments.

By combining the confined space operations with the foundation work, CWind provided additional synergies to the client and delivers a cost and time-effective solution.
The project site was subject to a high tidal range of 9m. The location of the works on the TP was in the tidal range, therefore working windows were limited to 5 to 6 hours. In order to maximise efficiency work hours were matched to low tides, with vessels, technicians and equipment ready on the platform as water levels began to drop. Extensive and specialist training ensured that our staff work in highly skilled teams to maximise time windows. When need and opportunity arose, CWind pro-actively undertok corrosion protection to correct damage to the protective layer caused in major installation works.
A few towers at West of Duddon Sands were suffering from jammed levelling systems which could potentially damage the transition pieces and cause a major delay to works. CWind’s project management designed a solution for cutting out the levelling systems in the confined space and atmosphere conditions and then trained all CWind technicians in this process to speed up foundation works and ensure quality delivery. In addition, the removal of the levelling systems required specialist rigging & lifting arrangements, such as hydraulic torqueing.
The multi-purpose vessel Cable Innovator was used to install a subsea power cable between two oil platforms in the Bay of Campeche, Gulf of Mexico.
As part of an upgrade program which was administered by Swecomex SA de CV, an offshore engineering company, the cabling provides vital power connectivity between Nahoch A and Takin A which are owned by Mexico’s national oil company, Pemex. Swecomex required a rapid and professional power cable installation to keep the upgrade project to time and budget.
The operations began in December 2006 and ended in April 2007.
Locating existing pipelines – Many of the oil and gas pipes had been buried deep into the ocean floor and had now become difficult to locate. Remotely Operated Vehicles (ROVs) were used, which have sensory devices, to locate exactly where the pipes were. The work required trained operators who controlled the ROVs from the Cable Innovator, to monitor a camera relayed from the ROV to the vessel.
CWind were awarded a 2 year contract to undertake a programme of statutory inspections and maintenance services on the 73 wind turbines at E.ON’s Humber Gateway offshore wind farm.

CWind, part of the Global Marine Group, was contracted by Western Power Distribution, to complete the vital power cable repair connecting the Isles of Scilly to mainland electricity.
The power cable was damaged by a ship’s anchor, a common occurrence with telecommunications and power cables, particularly within busy shipping lanes. The C.S. Sovereign, along with her crew of experienced cable engineers and specialist cable equipment and machinery, was contracted for the repair and rapidly mobilised. Using Remotely Operated Vehicles (ROVs) deployed from the back deck of the C.S. Sovereign, the vessel and technical team onboard surveyed the cable on the sea bed, located the fault and recovered the cable ends before successfully completing the joint.
The project was challenged by inclement weather, strong currents and restricted tide times but working together with the customer, Western Power Distribution, the repair was successfully completed within a month, without causing further disruption to the customers on the Islands. The cable was significantly damaged and there were several technical issues to overcome, but together the CWind and Global Marine Group team of experienced engineers were able to create an innovative solution. Not only was the damaged cable repaired effectively, but the new solution also created a shorter, more direct route between the connection points, when the cable was re-laid on the sea bed at a depth of 70 metres.
