Reporting system for assisting tugboats:.

Environment protection:.
Contamination, pollution and littering of waters, areas, objects and other port facilities are forbidden. In case of any events of this nature the perpetrators or users shall be obliged to remove the impurities immediately or at a time specified by the port authorities, bear the respective costs and reimburse the costs of any ensuing claims of any third parties.
Mooring:.
All the ships of 40 metres in length and more are obliged to use the local dock hands.
Pilotage:.
All the ships of 40 metres in length and more are obliged to use the pilot's services unless otherwise stipulated in part II of the regulations.
Irrespective of the ship's length the obligation of using pilot's services is applicable in the following cases:
a. ships carrying dangerous cargoes as provided for in § 16 and those which have not undergone gas-freeing after such trade;
b. overloaded or excessively trimmed ships or those having dangerous heel;
c. ships which due to suffered damages are likely to cause the contamination of environment.

Towage:.
The use of towing services in ports is obligatory as stipulated by these regulations. The harbour master may give an exemption to a vessel for a specified time or given port area not to use the towing services or a permission to use smaller number of tugs than that stipulated in part II of the regulations, if in his estimation the ship's manoeuvrability (eg availability of thrusters or similar arrangements) is unquestionable and if such exemption or permission does not constitute a danger to the navigation in harbour.
The harbour master may order using a tugboat by a ship or a bigger number of tugboats than that specified in the part II of the regulations, if so required in view of the safety of navigation.
