Opis:
In many sea areas there is significant recreational activity, with many sailing vessels and motor boats navigating, especially in coastal areas. Search and Rescue (SAR) organizations ensure the safety of people at sea, and are relatively frequently called to perform rescue or assistance missions to people in distress. Apart from the importance of adequate operational planning and training, rescue organizations benefit from establishing a robust, effective and cost-efficient response system. Risk-informed capacity planning can serve as a decision-support tool for determining the number and location of the required search and rescue units (SRUs). The purpose of this paper is to present such a risk-informed approach, which combines analysis of historic accident and incident data of recreational boating with information derived from Geographic Information System (GIS) methods. The method is applied to a case study focusing on the risk-informed capacity evaluation of the voluntary search and rescue services in the Finnish part of the Gulf of Finland. Results indicate that the response performance for recreational boating incidents is very good in most areas.

Opis:
Closest point of approach (CPA) is a basic factor taken into consideration for risk assessment during the meeting of two ships at sea. Navigators should use radars with automatic target tracking for collision avoidance and should know the accuracy to which radar data are calculated. Basic information about these requirements can be found in IMO resolutions. The currently binding document for devices manufactured after 2008 is IMO Resolution MSC.192(79). But there are two independent requirements for relative motion. One of these refers to relative motion parameters (relative course and speed) and the other one to the value that is the result of this motion (CPA). The other important document is Standard 62388. This specifies the minimum operational and performance requirements, methods of testing and the required test results published by IEC and also refers to radar equipment. However, this standard is not so popular in different publications focusing on radar equipment, so these requirements were not analyzed in the article. The main problem described in this paper refers to the mutual consistency of IMO Resolution requirements. The results of simulations and their analysis are presented.

Opis:
One consideration required in the resolution concerning radar and automatic radar plotting aid (ARPA) equipment is the possibility of an automatic drift calculation being realized in the base of fixed target tracking. This information is very important to providing safe navigation, especially in restricted areas. This paper presents an analysis of the present regulations contained in IMO resolutions and the results of an experiment conducted in the ARPA simulator. The aim of the simulations was to verify the reliability of the information presented on the ARPA display and to determine the accuracy of the automatic drift calculation implemented in the simulator.

Opis:
At present, providing a clear presentation of the navigational situation around a navigator’s own ship (OS) is one of the most important issues facing device manufacturers. Integration of navigational devices on the bridge has made it possible to transfer information and present it in the form chosen by the navigator screen. However, this may cause a decrease in the clarity of information and hamper its interpretation. The ability to select the best information, and that which is most needed at a given moment, depends on navigator proficiency. Vectors are still the basic form of the graphic presentation of radar-tracked object data. However, the ability to track more objects at the same time in crowded areas results in a decrease in readability and can cause errors. This article introduces the possibility of presenting information about collision danger in the form of Dangerous Courses Sectors (DCS) together with an analysis of changes in these during typical ship encounter situations. DCS are calculated on the base of Dangerous Passing Areas (DPA) as bearings on the marginal points of these areas.
