Heerema Marine Contractors’ new state-of-the-art Anchor Handling Tug Kolga was christened at Estación Maritima in Vigo (Sp) today. The christening was performed by Ms Caroline Heerema. Kolga is the sister tug of Bylgia which was christened last June.
Both Kolga and Bylgia were designed and built by Astilleros Armon Vigo, S.A. to replace HMC’s aging tugs, Husky and Retriever, who were both in service for over 30 years. Both new tugs are equipped with a retractable bow thruster and have DP2 capabilities. With a length of 72 meters and a width of 18 meters, the fully custom-built tugs are larger than the Husky and Retriever.
Each tug has a bollard pull of 202 tons and can hold up to 2500 m3 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 1500 meters. Each tug has accommodation for 40 people.
Kolga’s first task will be to tow the Thialf from Africa to the Gulf of Mexico.
