The most versatile vessels in Otto's fleet are its powerful Anchor Handling Tug Supply ("AHTS") vessels fitted with Dynamic Positioning capable of all types of towing and anchor handling activities.
Anchor Handling Tug Supply (AHTS) vessels combine the role of supply vessels and anchor handling tugs. They are the backbone of offshore operations and constitute the largest proportion of offshore vessels. Not only do they deliver supplies such as deck cargo, water, fuel, dry bulk and mud to oil rigs and platforms, they are specially designed to provide anchor handling services, towage duties and in some cases also serve as an Emergency Towing Rescue and Recovery Vessel (ETRRV). Some modern AHTS vessels are also equipped for fire fighting, rescue operations and oil recovery to enable them to have a more multi-role capability.
