Kincardine Floating Offshore Wind Farm | Case Study

An innovative and diverse project installing the export cable at the UK's first three platform Offshore Wind Farm Pilot at Kincardine.

Project: Kincardine Export Cable Installation

Client: Grupo Cobra

Vessel: Global Symphony

ROV: Q1400

Location: Northern North Sea

Activity: 18km export cable installation

Year: 2018

The installation of the first offshore floating windfarm in Scotland required significant pre and onsite engineering expertise brought to the project by our dedicated in-house resource.

The installation of the 18km export cable was completed by the team on board the highly versatile Global Symphony and marks the completion and connection of the first turbine on the 50MW Kincardine site.

“There are many advantages of building wind farm sites in deeper water. The floating technology utilised at Kincardine is relatively new to the market, and it’s great to be a part of developing these deep water solutions for the future.”
Mike Daniel – Managing Director, Global Offshore

In 2018 the Kincardine Floating Offshore Wind Farm pilot site, the first in the UK built using its three platform design, began producing energy. The Global Offshore team, utilising the Global Symphony and the Q1400, installed and trenched the export cable connection to the first turbine.

With a wealth of experience in power cable installation at offshore wind farms as well as a track record of working in the oil & gas sector, the Global Offshore team, part of the Global Marine Group, were able to call upon their combined experience to deliver this project successfully.

The overall project involved pre-installation surveys, grapnel work, cable installation, including the use of a dynamic riser to allow for movement of the platform, and trenching of the 18km export cable from Cove to the floating turbine, located just off the coast of Aberdeen.

Both ends of the cable were terminated and the cable energised ready for energy production to begin. This is the first of six turbines on the 50MW site.


After an initial meeting with the client at the beginning of August, the team began offshore operations, following cable load out in Norway, just over three weeks later on 1st September 2018.

Our responsive, in-house engineering expertise and project management during this planning phase, allowed us to quickly react, meeting the customer’s project timelines and complete the project in just a few weeks.


Rock bags were used at the subsea HDD exit to support the cable span between the HDD duct and the seabed. To further protect the cable in the transition from duct to seabed, cast iron split pipe was installed onto the cable at this point.

The highly capable Q1400 jet trencher was used, in hybrid mode, to trench the 18km cable from landfall to the turbine location.


The cable was laid between the HDD at the shore end towards the floating offshore wind turbine using the vessel’s cable lay equipment. Touchdown monitoring was provided by the vessel’s FCV 3000 ROV.

As part of the lay operation, uraduct was installed onto the cable where the dynamic riser touches down on the seabed providing mechanical protection to the cable from the motions applied by the floating structure.


A dynamic riser was used on the site to allow for movement on the platform. Buoyancy modules were installed onto the cable as well as it being routed through a bend stiffener before being pulled into the floating structure.

Experience at multiple oil & gas projects utilising similar technology at Floating Production Storage & Offloading (FPSO) vessels gave the team confidence in completing this part of the project, a technique new to the offshore renewable market.
