    Vessel & ROV News // December 16, 2013

    Heerema Marine Contractors’ anchor handling tug Kolga has been named at Estación Maritima in Vigo, Spain.

    Kolga and sister vessel Bylgia were designed and built by Astilleros Armon Vigo to replace HMC’s tugs Husky and Retriever.

    Both new tugs are equipped with a retractable bow thruster and have DP2 dynamic positioning.

    With a length of 72m and breadth of 18m, the fully custom-built tugs are larger than Husky and Retriever.

    Each has a bollard pull of 202 tonnes and can hold up to 2,500m3 of fuel, sufficient to sail directly from Rotterdam to Cape Town, South Africa. The anchor winch capacity is able to install anchors in water depths of up to 1,500m. Each tug has accommodation for 40 people.  

    Kolga’s first task will be to tow Thialf from Africa to the Gulf of Mexico.
