Chapter 10 provides for effective communications for ships and survival craft during normal and emergency situations, including explicit requirements for search and rescue (SAR) and telemedical assistance communications. Communication equipment on board shall have the capabilities for ship-to-ship and ship-to-shore communication, taking into account the limitations of communications systems in high latitudes and the anticipated low temperature. There must also be specific sound signalling equipment for use when under escort. Low temperature capability of communication equipment must be demonstrated by both ships and survival crafts. In respect of survival craft, equipment must be operable for the maximum expected time of rescue. These are clearly set out in the Chapter 10 wording below, and in the Part 1B Additional Guidance.
