Offshore Wind


We are a UK based worldwide business delivering both offshore wind inter-array cable layout optimisation consultancy and KLOC software licensing services. Our team have delivered more than a dozen offshore wind cable layout optimisation projects cumulatively totalling 13.1 GW, in addition to those projects undertaken by our clients under license.

What is KLOC?

Kinewell Layout Optimisation of Cable (KLOC) is a software solution that rapidly designs an economically optimised inter-array cable layout for an offshore wind farms, typically saving the developer 20% of cable system CAPEX over the lifetime of the project.

how does kloc work?

Our KLOC optimisation software creates offshore wind inter-array cable designs by utilising an evolutionary-based optimisation algorithm. The software appropriately prioritises the optimisation of capital cost (CAPEX) against operational costs (OPEX) such as electrical distribution losses and unavailability losses due to cable faults.

benefits of using kloc?

In addition to more cost-effective cable layouts, KLOC provides our licensed clients with productivity gains while developing optimised cable layouts, allowing client engineers to focus on tasks that cannot be automated and require critical human thought.

‘Our licenced solution can be accessed from anywhere, anytime, using desktop, laptop, tablet or mobile via an intuitive graphical web-app.’

IET Innovation award

The KLOC software was Highly Commended by the Institution of Engineering and Technology (IET) Innovation Awards in 2016 in two categories; Power and Model Based Engineering.

Track record

Our team has 13.1 GW of advisory experience in the European, Japanese, South Korean, US and Chinese offshore wind markets.  Our disclosable track record is below. To discuss your specific requirements, please get in touch.

Kinewell Energy utilised KLOC to optimise the inter-array cable layout of the 2 GW Beacon Wind project located in the US.

The work considered many different project uncertainties, such as: various turbine sizes, base and overplanting capacities, substation location, cable types and radial vs branched networks.

The cable layouts were optimised for both minimum CAPEX, and minimum of CAPEX plus OPEX considering electrical losses and unavailability losses.

The work provided information that de-risked numerous key client decisions while also identifying substantial savings over the project life.

Equinor, Beacon Wind, 2 GW


Inter-array cable system re-analysis for a major European developer to understand the savings achievable through innovative use of KLOC. The developer described the results as ‘relevant cost savings’.


The study demonstrated that some flexibility in turbine layout, asset crossings, cable type selection, substation positioning, and export cable routing are key to achieving optimized CAPEX and added revenues through reduced transmission losses.

Supporting the client in their tender for the project, KLOC was used to optimise the electrical connections for the 700 MW wind farm linking the 80 proposed turbines to the offshore substation. During the project KLOC evaluated in excess of 2.2 billion possible inter-array cable layouts.

KLOC was utilised to optimise the radial inter-array layout for the 680 MW wind farm consisting of up to 77 turbines. During the project KLOC evaluated in excess of 2.9 billion possible inter- array cable layouts.

A benchmarking case study to demonstrate the savings KLOC can deliver against the installed Gwynt- y-mor cable layout using publicly available data. The reoptimisation yielded savings of £2.2m. The total length of cable reduced by 1.7 km and the electrical losses reduced by 1.2 GWh per year.

Case study: Gwynt-y-mor, 576 MW


We funded the Kinewell Energy team to deliver on an innovation project that will lead to a new-to-market solution. Seeing Kinewell Energy’s pioneering ideas develop and become reality was very rewarding, and the company professionally delivered the project on time and on budget.


I have no doubt that the new solution will be a commercial success and add significant value to Kinewell Energy’s client base while supporting societal decarbonisation efforts.
