Norway's Simon Mokster Shipping has sold a platform supply vessel out of the over-tonnaged North Sea market.

The 4,500-dwt Stril Myster (built 2003) was laid up in April in Stavanger, Norway, as the combined impact of low oil prices and Covid-19 led to a rapid reduction in demand.

"Given the downturn in the market, and with a lack of reactivation opportunities in Mokster’s core markets for the foreseeable future, the vessel has been sold out of the offshore industry," Norwegian broker Seabrokers said.

The ship has been renamed Ocean Karadeniz under the new ownership of Turkey's Karadeniz Holding.

VesselsValue estimates the ship is worth $1.92m.

Karadeniz has been busy in recent months adding offshore tonnage for conversion to work in the powership sector.

The Turkish company confirmed the acquisition to TradeWinds and said the vessel may not be used for power work.

In May, Karadeniz bought the 8,255-dwt PSV Crest Angelica (built 2012) to turn it into a vessel with fully-integrated mounted floating power plants that supply electricity to shore communities.

Mokster has also not commented on the deal but announced that Aker BP has chartered the 4,600-bhp emergency response and rescue vessel Stril Mariner (built 2009) for a period of three months from November.

The vessel has been in service for Aker BP and its predecessor BP Norge for 11 years.

Singapore sales

Meanwhile, Singapore owner Britoil has offloaded a couple of its anchor-handling tug supply vessels in recent weeks.

The 6,600-hp Britoil 51 (built 2003) has gone for a reported $800,000 to India-based Jumbo Offshore Enterprise, brokers said.

The ship has been renamed the Maria I and reflagged from Singapore to India.

Separately, the 4,200-bhp Britoil 59 (built 2004) has been sold to undisclosed buyers in the United Arab Emirates.

The vessel has been renamed as Golden Star and reflagged from Singapore to St Kitts & Nevis.

The unit had been laid up for nearly a year in the United Arab Emirates prior to the transaction, Seabrokers said.
