Introduction to SOLAS Emergency Towing Arrangements
The International Maritime Organization (IMO) has set regulations under the Safety of Life at Sea (SOLAS) convention. These regulations aim to ensure the safety of ships and their crews in emergency situations. A key part of these regulations is the need for ships to have emergency towing arrangements. These systems allow a disabled vessel to be towed to safety by another ship, preventing further damage or loss of life.
Emergency towing arrangements include dedicated equipment at the bow and stern of a vessel. Their purpose is to enable the rapid deployment of towing gear in emergencies. The requirements for these arrangements differ based on the vessel type and age, with variations for tankers built before and after July 2002.
The IMO has provided detailed guidelines for the design and performance of emergency towing arrangements in MSC Resolution 35(63). These guidelines ensure the towing equipment can handle emergency towing forces and deploy swiftly when necessary.
The safe working load of the towing pennant should be at least twice the bollard pull of the towing vessel. The pennant should have a length of at least twice the freeboard height of the vessel or 50 meters, whichever is greater.
An emergency towing arrangement includes several key components:
Towing pennant
Strongpoint
Fairleads
Chafing gear
Storage drum or winch
These components ensure the towing gear can be deployed quickly and safely, even in challenging conditions. The towing pennant is the primary line, attached to the vessel's deck strongpoint. Fairleads and chafing gear protect the pennant from damage during towing.
Ships must also have emergency towing procedures in place. These procedures detail the crew's actions in an emergency, including deploying the towing gear and communicating with the towing vessel. Regular drills and training ensure the crew knows these procedures well, ready to execute them effectively when needed.
Requirements for Tankers Built On or After 1 July 2002
Tankers constructed post-1 July 2002, with a deadweight of 20,000 tonnes or more, must have emergency towing setups at both bow and stern. This is mandated by SOLAS regulations. Such arrangements are pivotal for shipboard safety, ensuring vessels can be towed swiftly and securely in emergencies. This enhances maritime safety standards.
Rapid Deployment Capabilities
Emergency towing setups on these tankers must be designed for swift activation, even without main power. This is a key aspect of contingency planning, ensuring the towing system functions efficiently in emergencies.
Pre-Rigged Emergency Towing Arrangements
At least one emergency towing setup must be pre-rigged for quick use. Deployment times are set as follows:
The aft arrangement should be ready within 15 minutes in harbour conditions.
The forward arrangement, not pre-rigged, must be deployed within one hour in harbour conditions.
These strict deployment times highlight the criticality of maintaining and accessing emergency towing systems. They are integral to a robust maritime safety framework.
Strength Considerations for Emergency Towing Arrangements
