This study aims to investigate the dangers associated with the use of conventional tugboats during towing operations, with a focus on the loss of stability caused by girting. There are many risks involved with towing, including grounding, fire, flood, collision, tug capsize, etc., depending on whether the tug masters are pulling at sea or at a harbour. The possibility of a tug capsize is increased by external factors such as girting. Girting can quickly result in tug capsizing, the loss of life, and / or possible environmental harm. An effective risk assessment strategy would aid in creating a successful towing plan in a towing operation where the consequences of poorly thought out actions are high. The formal safety assessment (FSA) method had been used to determine important events that lead to a tug capsize due to girting. For harbour tug operators, some guidelines and guidance on efficient risk management measures are also provided.
