Norway's Siem Offshore has hit out at rival owners taking "unsustainable" term rates to keep ships out of lay-up.
The Kristian Siem-backed shipowner said long-term charters are “still more or less absent” for anchor-handling tug supply (AHTS) units and offshore construction vessels.
But the company added that a handful of deals being accepted by other operators include unacceptable risk and unsustainable prices.
