PARIS -- Bureau Veritas has classed two series of ice-breaking tugs for service in the Caspian Sea.

The first series is for the North Caspian Sea Icebreaker, which has 50-metric ton (55-ton) bollard pull and Ice Class IA Super Special Service. The vessel can break ice up to 0.6 m (2 ft) in thickness. Designed by Aker Arctic, the vessel will be built in the STX RO Offshore Braila yard in Romania for the Caspian Offshore Construction group project in the North Caspian Kashgan oil field.

The second series is currently out to tender and is for shallow draft ice-breaking AHTS vessels. Designed by Netherlands-based Offshore Ship Designers for Silverburn Shipping, these vessels can work in 0.7 m (2.3 ft) of ice. They have a significant load carrying capability on a shallow draft and provide a minimum 45 metric ton (50 ton) bollard pull. Model tests at Aker Arctic showed the hull form can perform in ice to Finnish/Swedish Ice Class 1A Super standards.
