The Mangystau vessel is an icebreaking tug for extremely shallow waters, intended especially for pushing barges. In addition to towing and pushing, she is designed for ice management operations in astern working mode in ice rubbles reaching the sea floor.
The icebreaker can break level ice up to 60 cm and has a bollard pull of 50 tonnes.
The tug is equipped with a vacuum superstructure with air bottles, which allows survival and evacuation of up to 300 persons in an environment where a risk of Hydrogen Sulphide (H2S) is present. She is additionally designed for rescue operations, firefighting and oil spill recovery.
The series of five vessels were built and delivered in 2010 and 2011. Since delivery, the tugs have been working at the Kashagan oil field supporting the oil drilling platforms in the Northern Caspian Sea.
