Sima

Looks like she might be mobilising a diving daughter craft. Windfarms?

Ex Neftagas 66, her sister Neftegaz 12 was towed to Grenaa in Denmark in 2013 as the Clwyd Supporter for scrapping after being laid up in Sunderland for a few years, when she left Sunderland she looked in as good a condition as Sima, I wonder if she has been scrapped or given a new lease of life.

An old russian tug?

Apparently now owned or operated by JD Contractor a/s of Denmark, a marine and subsea contractor.
