A man broke his leg when the craft plunged into the sea off the Hook of Holland during work on the boat davits on the 5,800-dwt Nordic Nadja (built 1996), which was at anchor, Dutch media said.
A Dutch coast guard vessel battled through three and a half metre waves to bring the man to hospital after the incident on 8 October.
The drifting boat was recovered.
Earlier this year, French container line CMA CGM banned its crew from manning lifeboats during drills that involve lowering and hoisting after a fatal accident on one of its modern boxships.
[REMARK: the accident the text refers to took place on board the CMA CGM Christophe Colomb on April 15, 2011 in the Chinese port of Yantian. A deck officer and a cadet died. You can read the report of this casualty here]
