1 Categorization of pusher tug-barge combinations

 For the purpose of applying various safety standards to pusher tug-barge combinations, these should, when nothing else is specified in the standard in question, be categorized as type A or type B, where;

  1.1 Type A is a pusher tug-barge combination, which does not have the characteristics of a type B combination.

  • 1.1.1 A tug-barge combination, where the coupling is achieved by a completely rigid connection such as a bolt connection, should be regarded as type A, as well as a combination where the pusher can be manoeuvred by remote control from the barge.

  1.2 Type B is a pusher tug-barge combination with the following characteristics:

  • 1.2.1 The connection system should permit the pusher to move in relation to the barge.

  • 1.2.2 The connection system should permit the pusher to be easily disconnected from the barge. This should be tested in harbour conditions and should be achieved by one person in less than 5 minutes.

  1.3 This categorization is not intended to preclude any established interpretation of the words "rigidly connected" in regulation 12(s) of chapter V of the 1974 SOLAS Convention or Rule 24(b) of the 1972 Collision Regulations.
