That's it. Havengore working, London Array have issued a NtM about cleaning the transition thingies but I can't find it. I imagine there would be a exclusion round the cleaners.

That's it. Oh, have done a re-survey of the Ray Sand. The chartlet will be finished by the middle of the week, one further check to be finished. Best water is along the 1 degree meridian which has no more than 1.3 drying. In line with the Safe Water marks have a lump of sand drying 2.1m at chart datum.
