Offshore rates could weaken in the crucial summer season after Maersk Supply Service decided on a big switch of tonnage into the North Sea spot market.

Shipbroker SSY Offshore said the Danish giant has positioned eight anchor-handling tug supply units in the region, mainly on the UK side.

“With roughly 30 AHTS expected to operate in the spot market in the North Sea this high season, there could be downward pressure on rates,” the brokerage added.
