Opis:
The paper presents the preliminary information on the concept of open water model tests for assessment of safety of ships in damaged conditions. The need to develop the concept follows from the fact that the current regulations for assessment of safety of ships in damaged conditions require to consider an influence of many factors coming from different sources. Among the most important factors are those which come from the ship itself and the environment. Of course, the current regulations take into account the impacts which follow from the stages of flooding and progressive flooding but not all the possible impacts are taken into account. The open water model tests may enable to verify the existing regulations and model some phenomena associated with flooding. The open water model tests can be an important alternative method for the assessment of ship safety. The current method and some elements of the new approach to the safety of ships in damaged conditions are briefly described in the paper. A concept of the open water model tests for assessment of the safety of ships in damaged conditions are introduced. Some details regarding the research stand are given. The preliminary programme of investigations is presented as well. Because of the limited space available in the paper more details regarding the concept of open water model tests will be given in the POWER POINT presentation during the Symposium and in the final version of the paper.

Formal Safety Assessment (FSA)
Opis:
The paper presents some information on a performance-oriented risk-based model for assessment of safety of ships in damaged conditions. The design for safety process is integrated with the risk analysis. As safety is treated as one between the main design objectives such an approach is called the risk-based design. The assessment of safety is based on the risk level. The risk level is evaluated according to the risk-based criteria. For the risk analysis the Formal Safety Assessment methodology has been applied.

Opis:
This paper presents assumptions and process of the forming of a risk assessment model for collision between a passenger ferry departing from or approaching port of Świnoujście and a chemical tanker carrying a dangerous cargo. In order to assess navigational safety on the basis of data obtained from AIS system, were prepared probabilistic domains of ships, which made it possible to estimate number of navigational incidents as well as their spatial distribution , that consequently allowed to determine potentially dangerous areas. The next phase was formulation of a simulative model intended for the calculating of probability of collision between the ferry and chemical tanker as well as the determining of characteristic scenarios for such collision. This paper presents also an analysis of consequences of the collision with taking into consideration a damage of cargo tanks.

Opis:
This paper aims to show a practical case study of safety assessment concerning possible injuries and fire occurring in the engine room on-board a merchant ship, due to fatigue. Methods The methodology was centred in literature hazard identification, measurements in real ships and heat stress indices definition. Results Some corrections are proposed in order to obtain a safe environment for workers in the engine control room and to prevent fatigue risks at the engine room. This will allow adequate oil leakage detection and, as a consequence, improve fire prevention. Discussion Training is a preventive control option, but this study allows the understanding of new corrective control options like design corrections.

Opis:
This paper presents the results of applying ennobled solid biomass via mechanical compaction or torrefaction as fuel for ships, in terms of fire safety, environmental protection, the increase in liquid fuel prices and the dwindling resources of crude oil. The object of investigation is a ship of the ro-pax ferry type, with low cruising range, which is intended for service on the Baltic Sea. The ship’s power system is discussed and the results of calculations of the thermal cycle for a steam turbine power plant are presented. We present a simplified comparative analysis of a fuel bunker for a ship with a power plant including biomass fired boilers, and for a ship with a conventional solution of a motor power plant supplied by ultra-low sulphur fuel originating from crude oil. The advantages of applying a fluidised bed biomass fired boiler are highlighted, and selected results from tests of this boiler are presented. In addition, we assess potential fire hazards on the ship resulting from the storage and transport of pellets, and from pellets after torrefaction.

Opis:
The purpose and scope of this article is to present the best marine practices used to determine the ship’s domain depth (compared to the safety depth parameter in ECDIS) and the safest and best possible speed (also known as optimal speed) of the ship in restricted sea areas limited by the depth of navigation waters. The author also presents a method that can be used to estimate the safe speed of a ship in shallow waters and the so-called navigational risk factor (specified in the range from 0 to 1), using the safety depth parameter specified in ECDIS based on the analysis of a three-dimensional model of the ship’s domain. The essence of the method proposed in this paper is a systematic approach to the operation of a seagoing ship in the aspect of assessing its navigation safety (navigational risk factor) when manoeuvring in restricted sea areas, in particular in shallow waters including navigable canals and fairways.
