This is the Island Enforcer, moored off Kirkcaldy for a few days at the end of October. On the shipping websites she is described as an offshore construction vessel. She is not quite as Swiss Army Knife in looks as the Solitaire or Audacia of fond memory but still has some weird sticky out bits.
The first description I found of her was as a diving ship and I thought, “Isn’t that a submarine?” but she has been redesigned for offshore work.
More images of her can be found here.
