Pomorska navigacijska in radiokomunikacijska oprema ter sistemi - Ladijska oprema za daljnosežno identifikacijo in sledenje (LRIT) - Zahteve glede uporabnosti

Mednarodni standard IEC 62729 podaja zahteve učinkovitosti in metode testiranja za ladijsko opremo za daljnosežno identifikacijo in sledenje (LRIT). Daljnosežna identifikacija in sledenje ladij je zahteva uredbe V/19-1 Mednarodne konvencije o varstvu človeškega življenja na morju, 1974 (SOLAS 1974), kakor je bila spremenjena. Uvod za sistem je podan v dodatku A. Standardni rezultati pripomb, ki so jih imeli na sestanku Odbora za pomorsko varnost 88 (MSC) novembra 2010, da nekatera ladijska oprema za daljnosežno identifikacijo in sledenje ni delovala v skladu z določbami Mednarodne konvencije o varstvu človeškega življenja na morju in standardi uporabnosti, ki jih podaja Mednarodna pomorska organizacija. Standard upošteva splošne zahteve iz uredbe A.694(17) Mednarodne pomorske organizacije in se navezuje na standard IEC 60945. Če je zahteva tega mednarodnega standarda različna od zahteve standarda IEC 60945, ima prednost zahteva tega standarda. Ta standard vključuje dele standardov učinkovitosti iz uredbe MSC.263(84) Mednarodne pomorske organizacije, pregledane standarde učinkovitosti in funkcionalne zahteve za daljnosežno identifikacijo in sledenje ladij. Oprema, ki je bila testirana v skladu s tem standardom, bo, kot je prikazano spodaj, skladna z uredbo Mednarodne konvencije o varstvu človeškega življenja na morju in rezultati testa bodo pomagali vladam pri izdaji homologacij: (Mednarodna konvencija o varstvu človeškega življenja na morju V/19-1.6) Sistemi in oprema, ki je bila uporabljena za zadostitev zahtev te uredbe, se mora prilagoditi standardom učinkovitosti in funkcionalnim zahtevam, ki niso nižje od tistih, ki jih je sprejela Mednarodna pomorska organizacija. Homologacijo vse opreme potrdi vlada. Ta standard ne obravnava ladijskih naprav. Namestitev ladijske opreme je opisana v dodatku B. Preskus skladnosti ladijskih naprav Mednarodne pomorske organizacije ni vključen v ta standard, vendar so informacije o podrobnostih podane v dodatku C.

Overview

EN 62729:2012 (IEC 62729:2012) - Maritime navigation and radiocommunication equipment and systems - Shipborne equipment for long‑range identification and tracking (LRIT) - Performance requirements - specifies performance requirements and test methods for LRIT shipborne equipment. LRIT is mandated by SOLAS regulation V/19‑1; this European adoption (CLC/CENELEC) is identical to the IEC text and incorporates parts of IMO resolution MSC.263(84). Equipment compliant with this standard supports SOLAS type‑approval and helps Administrations and testing bodies verify LRIT performance.

Key topics and technical requirements

The standard focuses on functional and technical performance needed for reliable LRIT operation. Core topics include:

• Transmission of information - mandatory LRIT message content and successful delivery to LRIT data centres.
• Remote configuration & remote switching - secure means to update or enable/disable LRIT functions from shore.
• On‑demand reports - capability to respond to authorised requests for position and identity data.
• Functionality & coverage - operational availability consistent with SOLAS requirements.
• User controls - human interface, status indicators and tamper‑evident design considerations.
• Interfacing - electrical and data interfaces to shipboard systems (GPS/GNSS, power, comms).
• Environmental, EMC and survivability - environmental tests, electromagnetic compatibility (linked to IEC 60945) and recovery after power outage.
• Radiated spurious emissions - emissions limits referenced via relevant Radio Regulations and IEC test procedures.
• Methods of testing - defined test procedures and required test results (see Clause 6 and Annex C).

Note: where requirements differ from IEC 60945, EN/IEC 62729 takes precedence. Annex A provides an LRIT system introduction; Annex B reproduces installation‑related requirements.

Applications and who uses it

This standard is used by:

• LRIT equipment manufacturers - to design and verify shipborne units that meet IMO/SOLAS performance standards.
• Type‑approval authorities and Administrations - to assess compliance for SOLAS V/19‑1 type approval.
• Test laboratories and certification bodies - to perform the prescribed performance and EMC tests.
• Shipowners, shipbuilders and system integrators - to select compliant LRIT equipment and understand installation and interfacing needs.
• Classification societies and maritime regulators - for audit and survey guidance.

Related standards

• IMO MSC.263(84) - Revised performance standards and functional requirements for LRIT (incorporated).
• IEC 60945 - General maritime equipment requirements; EN 62729 is associated and supersedes IEC 60945 where different.
• SOLAS V/19‑1 - Regulatory requirement for LRIT carriage on applicable ships.
• ITU Radio Regulations - referenced for spurious emission limits.

EN 62729:2012 is essential for ensuring LRIT shipborne equipment is robust, interoperable and verifiable for global maritime safety and compliance.

MARITIME NAVIGATION AND RADIOCOMMUNICATION
EQUIPMENT AND SYSTEMS –
SHIPBORNE EQUIPMENT FOR LONG-RANGE
IDENTIFICATION AND TRACKING (LRIT) –
PERFORMANCE REQUIREMENTS
1 Scope
International Standard IEC 62729 specifies the performance requirements and methods of
testing for shipborne equipment for use for long-range identification and tracking (LRIT).
Long-range identification and tracking of ships is a requirement of regulation V/19-1 of SOLAS
1974 as amended. An introduction to the system is given in Annex A. The standard results
from observations made at the IMO meeting of MSC 88 in November 2010 that some LRIT
equipment in practice was not operating in accordance with the provisions of SOLAS and the
IMO performance standards.
The standard takes account of the general requirements given in IMO resolution A.694(17)
and is associated with IEC 60945. When a requirement in this International Standard is
different from IEC 60945, the requirement in this standard takes precedence.
This standard incorporates the parts of the performance standards included in IMO resolution
MSC.263(84), Revised performance standards and functional requirements for the long-range
identification and tracking of ships.
Equipment tested to this standard will demonstrate compliance with the SOLAS regulation as
indicated below and the test results will assist Administrations in granting type approval:
(SOLAS V/19-1.6) Systems and equipment used to meet the requirements of this regulation
shall conform to performance standards and functional requirements not inferior to those
adopted by the IMO. Any shipboard equipment shall be type approved by the Administration.
Shipboard installations are not covered by this standard but matters relating to the installation
of the shipboard equipment are reproduced in Annex B. The IMO conformance test of
shipborne installations is not covered by this standard but details are given, for information, in
Annex C.
NOTE All text of this standard, whose wording is identical to that of IMO resolution MSC.263(84) and the SOLAS
Convention, is printed in italics, and the resolution and associated performance standard paragraph numbers or
regulation are indicated in brackets.
