Communication technology in air transportation crews and cargoes to the Oil Rigs platforms. Along with the introduction, in the first part is brief overview of the historical development of radio communication from past till now. Then I continued with the equipment used in offshore or offshore communication between different vessels and aircraft. All radio devices are described individually and what their application are. Further, I explained the distances of offshore installations and the why are the helicopters are used in purpose of transporting crew and passengers, as well the necessary training and authorizations that all persons who are transported by helicopters to remote offshore installations must possess. In Chapter 5, I covered the training and preparation of remote offshore installation communications personnel who communicate and instruct pilots to land on on the helipad, and neccesery training of radio operators is essential to reduce the risk of accidents. The sixth chapter is the largest and in it I described in detail the procedure and other important information about communication between airplanes/helicopters, shore stations, airports and helipads on offshore installations. In the seventh chapter, have presented real data on accidents as well as the general safety of air transport to offshore installations are presented in concrete examples of the UK and Norway. In the eighth chapter, all the measures and preventions applied in helicopter transport are listed, while in the ninth, the personal protective equipment PPE (Personal protective equipment) that every passenger must have is dealt with, all for the purpose of reducing the risk of death in the event of a helicopter crash. In the tenth, I wrote my conclusion about general security.
