Any other vessel could have run full tilt into the derelict with major consequences. VTS with radar or MPA's with tracking and analysis could have spotted her before grounding.
    I accept that the USCG and RN are also culpable for allowing her to become derelict and later continuing to remain derelict. Our Surface picture is not interactive enough as we are missing surface scan by radar.
    Could the proposed installation of floating wind turbines off the SW coast provide a platform for Radar, extending our view off our most exposed, busy but remote coast? It's a shame that with the demise of Kinsale Alpha and Bravo we lose an AIS receiver.

    German 1: That is the bad news.

    Offshore wind turbines are a whole new area of development. They are fixed in water of less than 60metres depth but require a triple legged foundation instead of a mono pole type. Over 60 metres they are floating on anchors with certain vulnerabilities. The latter will require positional monitoring equipment in case of storm or collision movement. VTS radar could be installed on headlands with central monitoring stations per coastal sector. The French coast from Le Havre to the Spanish Coast is covered by coastal radar. If the radar at Roches point was operating it would have picked up ALTA.

    Wind turbines also can have a negative effect on radar

    Most likely and more so on anchored platforms with blades on a horizontal axis to reduce windage plus the effects of platform oscillations.
