| Sub-Committee on Radiocommunications and Search and Rescue (COMSAR), 10th session: 6-10 March 2006 Draft performance standards and functional requirements for the Long-Range Identification and Tracking (LRIT) were agreed by the Sub-Committee on Radiocommunications and Search and Rescue (COMSAR) when it met for its 10th session. The draft standards were forwarded to the Maritime Safety Committee (MSC 81) in May for consideration. The proposed draft SOLAS regulation on LRIT, which will be considered by the MSC for adoption, foresees:
The proposed draft amendments to SOLAS were developed by an MSC intersessional working group on LRIT (MSC/ISWG/LRIT) which met in October 2005. The Sub-Committee agreed an LRIT system architecture to consist of a number of LRIT Data Centres (National, Regional or Co-operative, or International) which interface and exchange information with each other through an International LRIT Data Exchange and which provide LRIT information to the LRIT Data Users (Contracting Governments and Search and rescue services) who opt to use their services. The Sub-Committee agreed that the main functions of an LRIT Data Centre should be:
The Sub-Committee agreed that each Contracting Government should instruct the ships entitled to fly their flag to transmit the LRIT information to the LRIT Data Centre selected by that Contracting Government. The Sub-Committee agreed that a number of technical specifications and other detailed technical requirements need to be developed for the LRIT system to be established and function in a smooth and efficient manner, and it agreed to invite the Committee to establish an Ad hoc LRIT Engineering Task Force for the purpose of developing the required technical specifications. Passenger ship
safety Draft amendments to SOLAS chapter III on recovery arrangements for the rescue of persons at sea were agreed, for submission to the MSC. The draft amendments would state that all SOLAS ships must be equipped to recover persons from the water and/or survival craft and rescue craft, and give functional requirements for achieving this. The Sub-Committee also agreed, for submission to the MSC :
Use of cellular
(mobile) telephones in maritime distress alerting The proposed amendments stress the fact that while popular, inexpensive, and multi-purpose, these devices have limitations in emergencies involving SAR in the maritime environment, and, therefore, the advantages dedicated marine communications systems should continue to be stressed by national administrations. In particular, where installed, cellular phone coverage in the maritime environment can be limited, intermittent, or non-existent, based on several factors including cellular tower accessibility and orientation in relationship to a cellular telephone call initiated from an offshore or coastal area. However, cellular service providers may be able to provide some help in finding the position of callers in an emergency. The Sub-Committee also agreed a liaison statement to the International Telecommunication Union (ITU), which concerns the possibility of creating a single common international cellular phone number for possible use by SOLAS ships within range of national cellular networks. Calls to this number would be directly routed to the national SAR Authority (MRCC) within the applicable Search and Rescue Region (SRR) from which the call is made, along with positional and caller identification information as is able to be made available. This common international SOLAS SAR number could be promulgated in nautical publications maintained by SOLAS ships. SART - revised
performance standards endorsed The Sub-Committee also endorsed preliminary draft performance standards for survival craft AIS Search and Rescue Transmitter (AIS-SART) to supplement the existing SART performance standards. The AIS-SART would use AIs technology. The Sub Committee
also endorsed draft proposed amendments to regulations in SOLAS chapter III
to reflect the development of new AIS-SART performance standards. Exchange of
medical information - draft circular agreed Criteria for
provision of communication systems in the GMDSS - revision agreed The proposed revisions note the decision of the MSC that the International Mobile Satellite Organization (IMSO) is the appropriate organization to carry out the required oversight of mobile-satellite services for the GMDSS. The revised resolution sets out the following general procedure: (a) IMO establishes the regulatory regime, via the revision of resolution A.888, which states that IMSO evaluates and approves satcom companies to participate in the GMDSS, undertakes the oversight on a continuing basis and keeps IMO (MSC) informed; (b) the Company applies - through its Government - to IMO. The application is reviewed by the MSC - which has a general discussion of principles and policy issues only - and forwards the application to IMSO; and (c) IMSO verifies the information provided and evaluates the application (the process is open and transparent with IMO and the sponsoring Government involved as Observers), decides on the acceptability of the applicant (based on criteria established by IMO in the revised resolution A.888) and, if appropriate, recognizes the applicant's services and conducts ongoing oversight. IMSO is also responsible for ensuring compliance - including any resulting enforcement procedures. Tsunami warning
system The architecture of the IOTWS was based on the establishment of national tsunami centres capable of issuing warnings in each of the participating countries through radio and TV broadcast and, possibly, mobile phone services. Between May and September 2005, national assessments of 16 countries in the vicinity of the Indian Ocean were conducted to identify capacity building needs and support requirements for the establishment of an Indian Ocean Tsunami Warning System (IOTWS). By July 2006 it is intended that an initial system will be operating utilizing 28 additional tide gauges and 25 seismic stations will be in place, together with the first three out of 60 planned open ocean buoys and updated communication facilities for data and warning exchange, Nevertheless implementing the complete system including all the intended instrumentation updates, the installation of all national warning centres as well as ensuring the effective communication of all warnings to the possibly affected population along the coasts will not be in place before the turn of the decade. The Sub Committee recognized that in respect of the threat to shipping a tsunami poses a significant risk only to those ships in shallow waters and in port areas; ships in port are not required to maintain watch on GMDSS communications equipment, consequently a separate system for promulgating warning messages needs to be established within each port; and tsunami warnings need to be sent to those ships most at risk in a rapid manner. The most important communication links were those between regional and national centres and it was noted that while new links being established appear to be predominantly by e-mail or through the WMO Global Telecommunications System, however use of the International SafetyNET system remains an option for IOC/UNESCO and relevant authorities if required. For communciaiton links within nations to coastal regions and ports; it was agreed that while this is a national issue, IMO, IHO and WMO can guide and support national authorities through national or regional capacity building programmes. For links to both SOLAS ships and non-SOLAS ships/fishing vessels in shallow coastal waters, NAVTEX can be used for these warnings, but there may be no stations currently covering the affected areas and non-SOLAS ships/fishing vessels may not carry suitable receiving equipment, therefore other means such as local news broadcasts and warnings on maritime VHF channels should be considered. It was recognized that options to use the IMO GMDSS communications facilities through either the relevant WWNWS NAVAREA Co ordinators or the METAREA Issuing Services, should remain available to national or regional centres if required by IOC/UNESCO. IMO, WMO and IHO should continue to participate in ongoing discussions, particularly at the IOC/UNESCO Assembly in June 2006, to ensure that maritime interests are not overlooked. It was also noted that IMO might wish to consider the provision of technical assistance to those nations under threat of tsunami and involved in the preparation and operation of Tsunami warning systems for vessels and ports.
