(a) Equipment shall be so designed that the main units can be replaced readily, without elaborate recalibration or readjustment. |
(b) Where applicable, equipment shall be so constructed and installed that it is readily accessible for inspection and onboard maintenance purposes. |
(c) Adequate information shall be provided to enable the equipment to be properly operated and maintained, taking into account the recommendations of the Organisation.18 |
(d) Adequate tools and spares shall be provided to enable the equipment to be maintained. |
(e) The Director shall ensure that radio equipment required by this Chapter is maintained to provide the availability of the functional requirements specified in Regulation 4 and to meet the recommended performance standards of such equipment. |
(f) On ships engaged on voyages in sea areas A1 or A2, the availability shall be ensured by using such methods as duplication of equipment, shore‑based maintenance or at‑sea electronic maintenance capability, or a combination of these, as may be approved by the Director. |
(g) On ships engaged on voyages in sea areas A3 or A4, the availability shall be ensured by using a combination of at least two methods such as duplication of equipment, shore‑based maintenance or at‑sea electronic maintenance capability, as may be approved by the Director. |
(h) While all reasonable steps shall be taken to maintain the equipment in efficient working order to ensure compliance with all the functional requirements specified in Regulation 4, malfunction of the equipment for providing the general radiocommunications required by Regulation 4(a)(ii) shall not be considered as making a ship unseaworthy or as a reason for delaying the ship in ports where repair facilities are not readily available, provided the ship is capable of performing all distress, urgency and safety functions. |
(i) EPIRBs shall be —(i) | annually tested, either on board the ship19 or at an approved testing station, for all aspects of operational efficiency, with special emphasis on checking the emission on operational frequencies, coding and registration, at intervals as specified below —(1) | on passenger ships, within three months before the expiry date of the Passenger Ship Safety Certificate; and | (2) | on cargo ships, within three months before the expiry date, or within three months before or after the anniversary date, of the Cargo Ship Safety Radio Certificate; and |
| (ii) | subject to maintenance at intervals not exceeding five years, to be performed at an approved shore-based maintenance facility.20 | 18 | Refer to General requirements for shipborne radio equipment forming part of the Global Maritime Distress and Safety System (GMDSS) and for electronic navigational aids (resolution A.694(17)), General requirements for electromagnetic compatibility (EMC) for all electrical and electronic ship’s equipment (resolution A.813(19)), and Clarifications of certain requirements in IMO performance standards for GMDSS equipment (MSC/Circ.862). |
