Offshore Wind Farm inner array grid cable installation on the Nordsee One OWF project as executed by Siem Offshore Contractors during the summer of 2016. The submarine cable installation was performed using the leading Siem cable installation Duo (Siem Aimery - Cable Lay Vessel and Siem Moxie - Installation Support vessel).

In the summer of 2016, VBMS completed their scope of work for the Sandbank Offshore Wind Farm existing of cable supply, CPS, installation, post lay burial and termination & testing of 76 infield cables. The Sandbank Offshore Wind Farm is situated in the German Bight, next to the DanTysk Offshore Windfarm. The 72 wind turbines will generate a total capacity of 288MW. For more information see www.vbms.com
The FASTER cable linking the U.S. and Japan will have a peak capacity of 60 terabits per second when it starts operating next year.

In December 2016, VBMS completed the installation of two 16 kilometre-long 150kV HVAC cables for the Rampion offshore wind farm situated off the coast of Worthing, UK. To overcome some environmental challenges in this very shallow water, VBMS had to extend the pre-installed landfall HDD’s with duct extensions of approx. 480 metres each. VBMS utilised Boskalis’ backhoe dredger Manu Pekka to dredge the trenches before installing the duct extensions. In addition, Boskalis dredged three flotation pits per cable routing to allow CLV Stemat Spirit to reach the location of the end of the ducts. Following the cable pull-in CLV Stemat Spirit jumped from pit to pit during high tides while laying the cable until it reached deeper water where it could safely remain afloat and resume the remaining cabl...
In October 2014, VBMS installed the export cable for the Eneco Luchterduinen Offshore Windfarm, executed by the CLV Ndurance and the Trenchformer. This unique multi-purpose trencher, developed and built by VBMS and Boskalis, used its jetting sword to bury the cable 3 metres deep near shore. See how we executed the shore end landing and the first 3 kilometres of simultaneous laying and burying of the export cable, captured in a 5-minute timelapse video.

PEFLEX is a cable protection system, manufactured by Pipeline Engineering, used to protect freespan array and export cables on offshore wind farms. Using PEFLEX allows diver-less and ROV-less installation. The PEFLEX design combines a series of interlocking polyurethane vertebrae half sections interspersed with elastomeric sleeves. PEFLEX is positioned at the subsea entry of cables on J-Tube or J-Tubeless connections. Once attached, PEFLEX limits the bending of cables by locking when the minimum bend radius is reached".
A short video to show the export cable pull in at the Burbo Bank Offshore Windfarm extension. There were some considerable engineering challenges to enable the team to get the cable installed safely. The cable was floated ashore on pillow floats to a small jack up barge then pulled through the tidal and connected to a winch for the final 760 metre pull through a HDD that had been installed 12 months ago. A great achievement for all involved!
Submarine cable installations in the telecom, power and seismic industries have similarities and differences. But there is a common thread in every submarine cable lay: you need accurate real-time control over the position and bottom tension of your cable as it lands on the seabed. This video discusses a proven method for achieving this control being used by over 75% of the telecom cable ships in the world. A tool called MakaiLay allows operators to precisely control the two most important variables in a cable installation: cable POSITION and TENSION. This software calculates all forces on the cable and can automatically adjust cable payout speed and vessel navigation to keep tension within acceptable limits, safely and accurately installing the cable on the seabed. Over the last 15 year...
Baltic Offshore Windfarm - First commercial windfarm in Germany in the Baltic Sea. nkt cables supplied 20 km of 30 kV three core medium voltage submarine cable (approx. 1,000 m each) with integrated fibre optics for the farm's own cabling and 60 km of 150 kV three core high voltage submarine cable with steel armouring and 3 integrated fibre optics for the grid connection • The high voltage submarine cable has a diameter of 24 cm and a weight of 115 kg/m • The longest individual section of the high voltage submarine cable has a weight of 1,850 tonnes • Development and delivery of 5 offshore joints • More than 15 ships were deployed during the installation phase, plus tugs and crew vessels • Supply of the VALCAP® monitoring system with AdapPro for grid monitoring
In June 2016, VBMS completed the installion of a 26.5 km export cable for the Nordergründe offshore wind farm. We have captured the pull-in of the cable - through the BSS-II - to the onshore substation in a two minute time-lapse.
New Hampshire Transmission is proposing to build a 68-mile underground/undersea transmission cable known as SeaLink. The project will help improve the reliability of the New England transmission system. This video shows the offshore portion of the cable route.
In August 2016, VBMS executed the first export cable shore landing for the Galloper Offshore Wind Farm utilising its newly invented method for lowering the cable onto the seabed without the use of divers, wet riggers or support vessels. By using a remotely controlled progressive buoyancy release system, VBMS is able to increase safety and efficiency by eliminating time-consuming interfaces. For more information contact vbms.com
