Anchor Handling Tug Supply (AHTS) vessels can supply oil rigs, tow them to location, anchor them up and, in a few cases, serve as an Emergency Rescue and Recovery Vessel (ERRV).

AHTS differ in the most part from Platform Supply Vessels (PSV's) as they are fitted with winches for towing and anchor handling and have an open stern to allow the decking of anchors, plus more power to increase the bollard pull. It ranges from 15 to 100 bollard pull
