M.1169 - Hours of Service of Ship Stations

Rec. ITU-R M.1169 1

RECOMMENDATION ITU-R M.1169*

HOURS OF SERVICE OF SHIP STATIONS (1995) Rec. ITU-R M.1169

The ITU Radiocommunication Assembly,

considering a) that there is a need to describe the working hours of ship stations,

recommends 1 that the hours of service of ship stations should be in accordance with Annexes 1 and 2.

ANNEX 1

§ 1. (1) For the international public correspondence service, ship stations are divided into four categories: a) stations of the first category: these stations maintain a continuous service; b) stations of the second category: these stations maintain a service for 16 hours a day; c) stations of the third category: these stations maintain a service for 8 hours a day; d) stations of the fourth category: these stations maintain a service the duration of which is either shorter than that of stations of the third category, or is not fixed by these Regulations. (2) Each administration shall itself determine the rules under which ship stations subject to it are to be placed in one of the above four categories. § 2. (1) Ship stations of the second category shall maintain the following hours of service: and, additionally, four hours of service at times to be decided by the administration, master or responsible person, to meet the essential communication needs of the ship, having regard to propagation conditions and traffic requirements. (2) Ship stations of the third category shall maintain the following hours of service: 0800 - 1200 ship’s time or zone time, two continuous hours of service between 1800 and 2200 h, ship’s time or zone time, at times decided by the administration, master or responsible person and, additionally, two hours of service at times decided by the administration, master or responsible person, to meet the essential communication needs of the ship, having regard to propagation conditions and traffic requirements. (3) Each administration will determine whether ship’s time observed by its ships is to be zone time as shown in Annex 2. (4) In case of short voyages, these stations shall provide service during the hours fixed by the administrations to which they are subject.

* This Recommendation should be brought to the attention of the International Maritime Organization (IMO). 2 Rec. ITU-R M.1169

§ 3. Ship stations of the fourth category are encouraged to provide service from 0830 to 0930 h, ship’s time or zone time. § 4. (1) Ship stations whose service is not continuous shall not close before: a) finishing all operations resulting from a distress call or from an urgency or safety signal; b) exchanging, so far as practicable, all traffic originating in or destined for coast stations situated within their service area and for ship stations which, being within their service area, have indicated their presence before the actual cessation of work. (2) Any ship station not having fixed working hours shall inform the coast stations with which it is in communication of the time of closing and the time of reopening its service. § 5. (1) Any ship station arriving in port, and whose service is therefore about to close, shall: a) notify accordingly the nearest coast station and, if appropriate, the other coast stations with which it generally communicates; b) not close until after the disposal of traffic on hand, unless this conflicts with the regulations in force in the country of the port of call. (2) On departure from port the ship station shall notify the coast station or stations concerned that its service is reopening as soon as such reopening is permitted by the regulations in force in the country of the port of departure. However, a ship station not having hours of service fixed by these Regulations may defer such notification until the station first reopens its service after departure from port.

Section II. Diagram and Map

Note a: This diagram indicates the fixed and elected hours of service maintained by ships of the second and third categories in terms of zone time. (The hours of service shown exclude those which are determined by the administration, master, or responsible person.) The fixed hours of watch are shown thus:

I) for ships of the second category:

II) for ships of the second and third categories:

III) for ships of the third category, period over which two continuous hours of service may be elected: D01
