North Sea platform supply vessel (PSV) owners are enjoying a spike in rates following a major shift of tonnage into the Baltic Sea.

Swiss contractor Allseas has been ramping up activity at its Nord Stream 2 project off Sweden and has snapped up 10 ships.

Seabrokers identifies Allseas as the charterer behind SD Standard Drilling's March award of two 185-day firm contracts for the 4,900-dwt Standard Princess (built 2008) and the 5,100-dwt Standard Supplier (built 2007).
