Offshore support vessels (OSVs) are still being delivered from shipyards into tough markets, but many more "stranded" vessels remain, particularly in China.
Clarksons Research said that of the 221 OSVs still on order, 172 were ordered pre-2015.
A total of 43 were delivered to owners in 2019, 31 of which were PSVs.
Seabrokers said the 5,000-dwt PSV Sea Gull has been handed over to John Fredriksen's Seatankers Management.
