Opis:: This paper presents an innovation methodology for quantity assessment the safety of dynamic positioning in locally confined area of technological work performance under nonlinear dynamic disturbances of environmental factors. The methodology is based on new integrated paradigm of prediction coordinated components interactions, which form dynamic positioning system. Proposed methodology implementation effect is based on the analysis of complex models that form the knowledge base. The comprehensive reserve of controllable thruster’s reactions was adopted as quantitative characteristic of dynamic positioning safety.

Opis:: This article deals with a very important problem, i.e. with the safety of shuttle tankers at sea. The author presents systems and mechanisms observed at these types of vessels which have great influence on safety both during loading and discharging operations, as well as at sea. A dynamic positioning system was introduced together with its subsystems and their role in increasing safety. Another issue discussed in this article is the problem of oil pollution during cargo handling operations and sea pollution resulting from accidents of tankers. This article also covers some problems connected with training of crew of these specialized vessels, operating the instruments and equipment installed on them and also with the maritime infrastructure. Some problems connected with navigation observed in some regions of the world were also discussed here. Transport of oil close to the coast is a branch of oil transportation in full swing. Each even the minor failure results in serious consequences for people, for vessels and for the environment. Constant development of new technologies used on shuttle tankers and constructing new vessels equipped with the most modern technical solutions aims at minimizing the risk of situations threatening people's life, situations dangerous for the vessel and the marine environment.

Opis:: Improving safety and reliability of ship propulsion system during dynamic positioning (DP) operations of multipurpose vessels is an essential advantage. It may be such possibilities obtained by application the considered solutions of propulsion systems and all other elements of energetic system. The minimum requirements were determined by creating the regulations of dynamic positioning systems and their levels. Applying the solutions, which were exceeded the limits of basic requirements, allows to increase the safety and reliability levels with a low rise the investment costs. Many marine companies try to invent so low cost solutions. An example analysed in the paper is the Wartsila LCC system. The applications of more complicated solutions in comparison to required duplicated systems are expensive. The cheaper solution is an investing in the development of automatics configurations (for those systems it was applied the triple and quadruple configurations) which in transient or emergency conditions may obtain the time delay making possible a support of industry part work and DP systems. In emergency situation, after the loss of position by DP system, the power management system allow the safe break of work the industry part and return to work after elimination the critical condition.

Opis:: Ship propulsion configurations with dynamic positioning systems are commonly used as diesel-electric. In particular, situations for ship transfer on longer distances may be used conventional mechanical propulsion system with controllable pitch propeller. Combination of mechanical and electric propulsion system called hybrid propulsion is met as well, where the thrusters of DP systems are driven through the gear by mechanical engine or electric motor independent or both. For the sake of the necessity of limitation of total installed power on the ship may occurred problems with power distribution between the ship propulsion and industry part. It will especially concern those situations when we need to keep power supply to the industry part and there is a necessity to increase the power delivered to ship propulsion part for the purpose of keeping the ship position or heading. The primary task of power management system (PMS) is blackout prevention in ship energetic network and so power distribution to overcome critical conditions of it. Temporarily it may occur the worsening of positioning operation accuracy without any critical situations of industry part. The possibility of momentary overloading of energetic network is primary condition of safety. The critical duration of overloading is one minute. This is indispensable time for increasing the accessible power in the energetic system through switching on the next genset to work. It is a necessity of quick analysis in critical conditions to value what key-actions ought to do in the aim of overcoming emergency situations. The next one is a usage of energy storage devices. It is possible through AC/DC conversion. It was tried to find solutions of equalization the load of gensets to the ship electric energy demand.

Opis:: This paper explores concerns regarding the design, implementation, and management of alarms in DP vessels that, while in operation, need an incredibly high level of accuracy along with high reliability and safe operations. The Human, Technological, and Organizational factors (HTO) method is primarily used as analysis tool to find weaknesses in alarm handling during DP operations. The research focuses on results collected from Dynamic Positioning Operators (DPO) and instructors. Findings from the survey are presented and compared to the results from past accidents and technical requirements from Petroleum Safety Agency Norway via YA 711. Three accidents from past are referred to picturize the findings from the survey results. Furthermore, the conclusion is given with recommendations reflecting the findings from the survey. The main findings are an urgency to establish a centralized marine accident investigation system which enforces learning and recommendation to make operations safer. In addition, the survey also suggests that prohibition of clients or limiting their access to the bridge is necessary. Manufacturers could focus on research and development of alarm prioritization, on structuring and presentation, and profiting by taking feedback from end-users to make DP operations safer.

Opis:: The article presents the issues related to the analysis of signals monitoring the operation of ship equipment. Monitoring systems, purpose of their application and functions are briefly discussed. Signals used in monitoring and control systems of the ship power plant using additional, more detailed analysis can be used for additional diagnostic systems. The article presents research done in the real state of the ship system operation. Focus has been put on characterizing damages of sensors or devices. The problems of poor interpretation of failure symptoms by the operator and the alarm system were discussed.

Opis:: W artykule omówiony został problem ograniczeń projektowych siłowni statków z systemami dynamicznego pozycjonowania związanych z poszukiwaniem rozwiązań umożliwiających uzyskanie odpowiedniej klasy DP przy ograniczonych kosztach inwestycyjnych. Kompromis uzyskany w fazie projektu ma istotny wpływ na występujące ograniczenia podczas eksploatacji statku i jego siłowni. Sytuację częściowo ratują wymagania towarzystw klasyfikacyjnych, które wymagają stosowania określonych rozwiązań, które nie pozwalają na daleko idące uproszczenia. Uzyskanie, a później utrzymanie przez statek klasy DP 2 lub DP 3 (wg projektu), wiąże się z możliwością uzyskania wyższych stawek za prace wykonywanie przez statek. Wyższa klasa dynamicznego pozycjonowania zapewnia zarazem większe bezpieczeństwo statku i załogi w stanach awaryjnych.
Paper discussed the problem of design and operation limitations of ships with dynamic positioning systems having an influence on solution’s search giving possibility to get required IMO DP class at limited investment cost. Compromise obtained in design phase has an essential effect on the operation limitations during ship operation and ship’s power plant exploitation. Regulations of classification societies partially save the situation, require the application of specified solutions, don’t allow on simplifications going too far. Getting and later keeping the DP2 or DP3 class through the vessel (according to design) gives the possibility to obtain higher rates for ship’s operation. Higher class of DP system ensures higher ship’s safety and crew especially in emergency states.
