Client: Brough Head Wave Farm Limited


Brough Head Wave Farm Limited (BHWFL), a partnership between renewable technology developer Aquamarine Power Limited (Aquamarine Power) and SSE Renewables UK Limited (SSER), was granted an exclusive Agreement for Lease (AfL) on an area of seabed off the Mainland Orkney coast for the development of commercial scale wave energy. The suitability for development according to a number of constraints varied considerably across the site. Xodus assisted BHWFL in performing coarse option ranking in order to identify the preferred development sites. Seven sites were identified for comparison.

The site selection ranking exercise was undertaken using Xodus' option ranking methodology, Value decision Risk Management (VDRM). The Project drivers / goals were identified by the Brough Head Wave Farm Limited (BHWFL) Project Manager, SSE Renewables Project Manager and Xodus Group Project Manager and subsequently developed by members of the BHWFL project team prior to agreement at the option ranking workshop.

The results of the assessment indicated that of the seven options considered, two options provided a more attractive contribution to achieving the project drivers / goals. Other options were less attractive in terms of satisfying the project drivers / goals in one or more areas.

  • Identification and definition of project drivers / goals including pair-wise comparison against each other using the Analytical Hierarchy Process to derive weightings
  • Description and constraints mapping for each potential development site
  • Definition of the proposed site options against the project drivers / goals, including capturing the ‘Record of Discussion’ which provided transparency of the scoring of the options against the goals
  • Production of final scoring for each option against the project drivers / goals, which was used to identify those options that maximised the contribution to achieving the project drivers / goals
