These include the proper use of marine radar and the taking of bearings by ship's compass to determine if there is a steady bearing and risk of collison. [11] Rule 8 – Action to Avoid Collision. [12] [13] This rule sets out requirements for vessels to alter course and/or speed to pass a safe distance with other vessels. [12]
This resolution amends Chapter V of the International Convention for the Safety of Life at Sea (SOLAS), regulation 19-1 and binds all governments which have contracted to the IMO. [2] The LRIT regulation will apply to the following ship types engaged on international voyages: All passenger ships including high-speed craft,
IMO requirements under the SOLAS resulting from an amendment of June 5, 2009, [5] [6] [7] come into force on the following dates for ships classified by size: July 2011: new vessels in excess of 150 tonnes. July 2011: all passenger vessels July 2012: all vessels in excess of 3,000 tonnes July 2013: all vessels between 500 and 3,000 tonnes
The detection range between these devices and ships, dependent upon the height of the ship's radar mast and the height of the Search and Rescue Locating device, is normally about 15 km (8 nautical miles). Once detected by radar, the Search and Rescue Locating device will produce a visual and aural indication to the persons in distress.
The IMO requires automatic-activating Cospas-Sarsat beacons (EPIRBs, see below) on all vessels subject to requirements of the International Convention for the Safety of Life at Sea (so-called SOLAS-class vessels), commercial fishing vessels, and all passenger ships in international waters.
The International Maritime Organization (IMO) states that "The International Ship and Port Facility Security Code (ISPS Code) is a comprehensive set of measures to enhance the security of ships and port facilities, developed in response to the perceived threats to ships and port facilities in the wake of the 9/11 attacks in the United States".
A SART will only respond to a 9 GHz X-band (3 cm wavelength) radar. It will not be seen on S-band (10 cm) or other radar. Shipboard Global Maritime Distress Safety System (GMDSS) include one or more search and rescue locating devices. The radar-SART may be triggered by any X-band radar within a range of approximately 8 nautical miles (15 ...
When a racon receives a radar pulse, it responds with a signal on the same frequency which puts an image on the radar display. This takes the form of a short line of dots and dashes forming a Morse character radiating away from the location of the beacon on the normal plan position indicator radar display. The length of the line usually ...
