Heavy lift ship Bokalift 1 at Great Yarmouth; 10 September 2019

Converted from a semi-submersible load carrier to a crane ship, capable of a 3,000 ton lift, Bokalift 1 has been employed recovering rig components for scap from the seabed between Gt Yarmouth and Lowestoft on the UK east coast.
She's seen here approaching the outer harbour at Great Yarmouth.

Never seen the 'No Welding' sign before, it's normally no smoking.
