Installation might take 1 hour but it still takes 1 day to mobilise the boat to Nigg, 1 day to load it, 1 day to travel to site, 1 day to prepare and wait for the right tide (sometimes more, as in the current case), 1 day to return to Nigg and unload kit (and sometimes a turbine) and 1 day to demobilise the vessel.
Even assuming some overlap between these steps that’s 5 plus days hire of a vessel that costs £100k a day, or about £500k for each operation. Shaving a few minutes off installation might cut time on site by half a day if it means they can work in an earlier slack tide. That’s valuable, but only part of the picture.
