This book has been written to provide the Master of a tug with essential knowledge and techniques that can be applied when connecting a tug to a MODU which requires rescue towing, or a vessel requiring a tow within an oilfield. Previously published by Clarkson Research Services Ltd.

The purpose of this book is to provide practical seamanship guidance to Masters and crews of salvage, anchor handling and other tugs planning and conducting rescue towage within, and in close proximity to, oilfields. The personnel and crew serving on vessels and MODUs within oilfields will also learn how tugs operate during rescue towage. When planning for contingencies, both from a shoreside and a vessel perspective, this publication will assist in providing an overview of methods available for reconnection and other options that vessels find most practicable. Rescue towing in the context of this publication includes reconnection by a tug to a towed object when the original towline is broken, assisting another tug that has lost control of its tow, when additional tow power is required or when towage services can be offered to a vessel or unit requiring the services of a tug to avoid marine peril. This is not a definitive guide for professional salvors.
