Offshore charterers have seen rates for North Sea anchor-handlers leap this week as tonnage runs short.

Demand has been steady, with 10 ships fixed already since the end of June.

Dof's 260-bp Skandi Hera (built 2009) has topped the list at £20,000 ($25,800) per day from ConocoPhillips for the Ensco 120 rig move. This is up from £12,000 last week.
