An offshore vessel provider to the oil and gas industry, DOF, has secured two new charter contracts for two of its Anchor Handling Tug Supply (AHTS) vessels.

DOF stated on Tuesday that their subsidiary, DOF Management Australia has signed two contracts with Schlumberger Asia Services for the Skandi Emerald and Skandi Giant.

The company said the contracts will start in May and have a duration of 120 days with an option of a five week extension.

The Skandi Emerald, built in 2011, is a new generation high powered anchor handling vessel designed for field installation operations across a wide range of water depths and environmental conditions. The other contracted vessel, the Skandi Giant was built in 2002 and was mostly operated by DOF along with Norskan Offshore in Brazil.
