AHT (Anchor Handling & Towing) Course

Anchor Handling Towing

Purpose

Anchor Handling and Towing Course is to enhance safety and give a thorough understanding of the theory and practice in anchor handling and winch operation. Anchor Handling Tug Supply (AHTS) vessels are mainly built to handle anchors for oil rigs and platforms, tow them to location, anchor them up and, in a few cases, serve as an Emergency Rescue and Recovery Vessel (ERRV). The supply function means that they are used to transport equipment and materials to and from offshore drilling rigs. This course is developed to provide good practice especially in anchor handling operations for mobile offshore drilling units (MODU).

Target Audience

Deck Officers taking up job on offshore AHTS vessels will gain in depth working knowledge from Anchor Handling and Towing Course.
