Chapter 1 - GENERAL DESCRIPTION


1.1 General


1.1.1 This booklet is prepared for use in emergency towing situations in accordance with SOLAS Ch.II-1, Regulation 3-4 and related MSC.1/Circ.1255.


1.1.2 The following information is included in this booklet:


a) Drawings of fore and aft deck showing possible emergency towing arrangements;


b) Inventory of equipment on board that can be used for emergency towing;


c) Means and methods of communication;


d) Sample procedures to facilitate the preparation for and conducting of emergency towing;


e) Organization of tasks; and


f) Communication plan listing all information that is required to be communicated to the towing ship.


1.1.3 A copy of this booklet should be kept at hand by the owners/operators. A copy should be also kept in a common electronic file format, which will allow faster distribution to the concerned parties.


1.1.4 A minimum of three copies should be kept on board and located in the following locations:


a) The bridge;


b) A forecastle space; and


c) The ship’s office or cargo control room.


1.1.5 Owners, operators and crew should take into consideration that the nature of an emergency does not allow time for deliberation. Accordingly, the procedures should be practiced beforehand.


1.1.6 Typical procedures for connecting towing lines are introduced in Chapter 6 of this booklet.






1.2 Limitation during towing operation


1.2.1 Not all ships have the same degree of shipboard equipment, so that there may be limits to possible towing procedures. Nevertheless, the intention of this booklet is to predetermine what can be accomplished.


1.2.2 The towing load should not exceed the safety working loads of deck fittings as shown in 2.8 and 2.9 of this booklet. When heavy weather which will significantly increase the towing load is forecasted, special considerations are to be paid to the towing speed, towing line arrangement, and ship’s stability.


1.2.3 The loading points on stand-rollers are so high that great bending moments are generally transferred to the supporting structures. Consequently, stand-rollers are not to be used in towing line arrangement as far as practicable.






1.3 Master’s response


1.3.1 The master of a ship or shipowner’s representative, when recognizing that the ship is in distress and may need towing assistance, should make the initial notification of the incident to the following parties:


a) Nearest port states;


b) Flag states; and


c) Other relevant parties (shipper, insurer, etc.).


1.3.2 The master should complete the tables in Chapter 7 ‘CURRUENT STATUS’, and prepare to communicate with the towing ship.


1.3.3 All information from Chapter 1 to Chapter 7 of this booklet should be delivered to the towing ship.


1.3.4 The master should ensure that towing lines do not become taut until towing lines are tied to the connection system of towing ship and that everyone on deck have been notified.


1.3.5 When the power system on board is not available or alternative connection procedures are introduced by the towing ship, the master should try to make a best decision possible considering the ship’s current status in consultation with the towing ship.


1.3.6 When an alternative procedure is adopted, it should be well informed to all staff.


1.3.7 The master should ensure that survival crafts are made ready for use.


1.4 Safety considerations


1.4.1 The Chief Officer on the mooring deck should be in contact with the Bridge at all times.


1.4.2 Everyone on deck should be equipped with personnel life saving appliances and be alert to avoid hazardous situations such as slips, trips, fall, etc.


1.4.3 All crew should be well informed of the work procedures and tasks.


1.4.4 When the towing line becomes strained in tension, all on-deck staff should be evacuated to a safe location.


1.4.5 The crew should have a good knowledge about the equipment stowage location and its accessibility. Any identified improvements to stowage arrangements should be implemented.


1.4.6 Whilst engaged in towing operations, the minimum number of crew essential to carry out duties is to be on deck, and they should never be exposed to a rope or wire under tension or load. Wherever possible, the deck should be cleared of crew whilst towing.


1.5 Towing preparations


1.5.1 It is recommended that the towed ship is to display the navigation lights, shapes and, if manned, make sound signals required by the International Regulation for Preventing Collisions at Sea, 1972, as amended. Due consideration should be given to the reliability of the lights and sound signals and their ability to function for the duration of the voyage.


1.5.2 Prior to sailing, the watertight integrity of the towed ship should be confirmed by an inspection of the closing arrangement for all hatches, valves, air pipes, and other openings through which water might enter. It should also be confirmed that any watertight doors or other closing arrangements within the hull are securely closed and that any portable closing plates are in place.


1.5.3 The securing arrangements and weather protection for the cargo, equipment and store carried on the towed ship should be carefully examined to ensure that they are adequate for the voyage.


1.5.4 When appropriate, the rudder should be secured in the amidships position and measures should be taken to prevent the propeller shaft from turning.


1.5.5 The towed ship should be at a suitable draught for the intended voyage.


1.5.6 The towed ship should have adequate intact stability in all the loading and ballast conditions to be used during the voyage.


1.5.7 Life saving appliances in the form of lifejackets and lifebuoys should be provided whenever personnel are likely to be on board the towed ship even if only for short periods of time. When personnel are expected to remain on board for longer periods of time, life rafts should be provided. Other life saving appliances, including distress signals, fire appliances and radio equipment, including means of communication with the towing ship, should be provided whenever the towed ship is continually manned.

Chapter 5 - DECISION MATRIX


5.1 Decision matrix for determining towing pattern


5.1.1 The towing pattern should be decided by the ship’s master, in consultation with the master of towing ship, by using the following Decision Matrix.


5.1.2 The ship should be towed from the bow as far as possible. If it is not possible to tow from the bow for some reasons such as grounding, collision, etc., towing from the stern may be selected as an alternative.


5.1.3 For determining the towing pattern, the following status and surrounding conditions should be taken into account.






a) Ship’s position;


b) Weather and sea conditions;


c) Short-term marine forecast for the area of the incident;


d) Direction and rate of drift;


e) Distance and estimated time to any possible grounding location;


f) Availability of propulsion system; and


g) Availability of power supply for deck machinery.


5.2 Decision matrix (if ETS is not fitted)


Condition Towing pattern Status


Bow Stern


Imminent and immediate danger, e.g. risk of grounding in less than 1 hour


F1


A1


1. The pattern F1 or A1 is to be used provided that the towing force is controlled so as not to exceed the Safe Working Load (SWL) of the deck fittings.


2. If the weather is severely bad, the additional towing lines are to be connected between the towed ship and the towing ship.


The duration of being towed is long


F2


A2


1. If possible, the two (2) set of towing lines are to be used.


2. If possible, a chain is to be used so that the towing force can be controlled so as not to exceed the Safe Working Load (SWL) of deck fittings.


5.3 Decision matrix (if ETS is fitted)


Condition Towing pattern Status


Bow Stern


Imminent and immediate danger, e.g. risk of grounding in less than 1 hour


F3


A3 1. The pattern A3 is the preferred method in this condition, time of deployment is less than 15 minutes.


2. Alternative Pattern F3 if the time allowed is 1 hour.

  1. This is a good book for the general public to train them about how to react in case of emergency and how to do towing and rescue work.
