Abstract
The purpose of this paper is to provide guidance to developers in determining an appropriate margin of safety over turbines where there is no safe and reasonable deviation for marine traffic using the area,– to allow adequate safe under keel clearance (UKC) - and hence minimum water depth for vessels transiting over, tidal devices and their associated structures.
This Paper is intended to assist discussions between developers and MCA and represents guidance only. Developers are free to deviate from the approach where they consider it necessary, can present a sound argument for doing so and/or offer mitigation measures.
Additionally, it is intended that this paper assists developers in identifying suitable locations for underwater devices when considered in the context of available water depth, vessels and craft that transit the area. However, it is not intended that this paper removes the need for developers to consult with the relevant regulator and advisors.
This UKC guidance addresses the worst case scenario, each specific development will have its own unique characteristics and will therefore be assessed on a case by case basis.
