Should an oil spill of tier III magnitude occur in the Northern Adriatic, there is a high probability that the oil will reach and pollute the surrounding coastline. Therefore, it is vital to conduct coastal vulnerability studies to develop priority plans and coastal vulnerability maps to help first responders protect the coastline. As there is no common contingency plan for oil spills in the Northern Adriatic, three countries, Italy, Slovenia, and Croatia, which share the area, decided to participate in the North Adriatic Incident Response System (NAMIRS) project. Part of the project was to conduct a coastal vulnerability study in the area. One of the three pillars for determining vulnerability, in addition to the ecological and geomorphological factors, is the socioeconomic aspect, which was studied as part of the research. As there are no clear scientific methods to determine the vulnerability of the socio‐economic factors, a survey was conducted where the participants gave their subjective opinion on its value. This was done through three workshops organised in each participating country, where professional stakeholders familiar with the state of socio‐economic activities assessed their vulnerability. The values obtained were combined with the assessments of the geomorphological and environmental factors and gathered in a coastal vulnerability layer, which was incorporated into a GIS as a standard coastal vulnerability map that will help first responders prioritise coastal protection. The research results will also be useful globally and not just in the area studied by NAMIRS, since the method used is readily applicable to any part of the world.

The paper presents the overall risk management state for the crude oil tanker fleet, evidenced by EMSA and other international marine organisations. Based on historical statistical data related to fleet size, accident reports, amount of oil spilled on the sea and the economic value of the crude oil transport business, the risk acceptance criteria are evaluated. The Formal Safety Assessment is further used for a systematic assessment of risk, where potential hazards are analysed with structured methods (HAZID) and represented in event trees. The paper studies three risks: PLL (potential loss of lives), PLC (potential loss of containment) and PLP (potential loss of property). A general approach is presented and discussed with a particular focus on the evolution of risk acceptance in recent decades and evaluations of risk F-N curves for different tanker sizes.

The continuing growth of the LNG (liquid natural gas) industry has led to a rapid increase in the construction of LNG terminals and the need for accurate risk assessment models as accidents involving LNG are potentially hazardous and pose a major threat. One aspect of risk modeling - evacuation of people to the safe zones of an LNG terminal - is a complex problem that has yet to receive sufficient attention. The aim of this paper is to illustrate how the implementation of a technologically advanced evacuation model may decrease risk during potential accidents in an LNG terminal.

Evacuation of people located inside the enclosed area of LNG terminal is a complex problem, especially considering that accidents involving LNG are potentially very hazardous. In order to create an evacuation model managed through fuzzy logic, extensive influence must be generated from safety analyses. A very important moment in the optimal functioning of an evacuation model is the creation of a database which incorporates all input indicators. The output result is the creation of a safety evacuation route which is active at the moment of the accident.

The research explained in this paper was carried out to investigate the efficiency of different steering systems on sailing yachts. The steering system of a sail yacht mostly includes a simple steering system and a hydrodynamic shaped single rudder or multiple rudders, depending on boat characteristics. One of the basic design guidelines for fast sailing yachts is to reduce wetted surface to minimum allowed by the dynamic stability and maintaining the sailing performances. Deficiencies of different steering systems are discussed and their influences on total drag and yacht manoeuvrability in different sailing directions is analysed. The discussion is focused on steering systems applicable in practice and accepted by the yacht-building industry, although several innovations could be found that remained on their development stage because of their complexity in construction, maintenance, use itself and reliability. All measurements have been conducted at sea applying on board sensors for position and accelerations acquirements. The purpose of the research was to demonstrate that the use of the bended rudder can reduce the leeway angle, the upwind sailing angle and increase the velocity made good to windward.
