Brokers believe new deals for anchor-handling tug supply (AHTS) ships in the North Sea are setting all-time records.

Christen Sveaas’ Viking Supply Ships has fixed a trio of vessels at a “monstrous” £190,000 ($233,000) per day for rig moves, thought to be the highest number ever seen in the spot market.

Spain’s Repsol had to pay this rate for 19,050-bhp Brage Viking (built 2012) and Njord Viking (built 2011) for the Stena Don rig move in the UK.
