A passenger ship is consist of five(5) constituents; passenger, sea, crew, port and ship itself and the rule & regulation which is applicable to passenger ship are differently required as their objects of constituents. the basic concept of rule & regulation can be defined all activities to keep safety of ship and her constituents. Especially, the rule & regulation for passenger ship design and construction shall be considered not only safety of ship itself but also safety of lives, so its are required more severe than commercial vessel. Recently, the IMO have finished the rule making work on the 'passenger ship safety' since it has been discussed last 2000 and next MSC meeting will be adopted the results. In this paper, the application method of rule & regulation are treated and the new rule which were made by IMO are introduced. The rule & regulation for passenger ship is one of the most important things. therefore, it is required to careful consideration to apply on the rule application.

In this study, we investigated the activity data and basic data of the surface of the water within the ship to be operated by lakes and rivers inland. In this study previously, there was no survey activity data of Ferry and Cruise ship in Korea. In order to ensure the basic data and development of measures to reduce efficiently by local governments, these studies should be performed. Therefore, in the present study was survey the activity data such as cruising time and engine load factor and the specifications of the vessels. As a result, by analyzing the cruising pattern according to the area and the purpose of the cruise, to calculate the emissions of greenhouse gases.

Due to the rise of international oil prices, with the continued increase of vessel operating costs, profitability has gradually deteriorated in the some case of South Korea ferry shipping. Therefore, it is necessary to improve the resistance performance of passenger ship. Goose neck bulb can be one of the methods to improve the resistance performance of passenger ship. Goose neck bulb has been applied to passenger ships operated in Europe and large cruise line. But there is no application example in the passenger ship to be operated on a regular basis in the sea near Korea. It is needed to provide reference data that can be applied efficiently goose neck bulb on the medium-sized passenger ships. This study, intended for the medium-sized passenger ship operated short international routes, presents the design of the hull form that goose neck bulb has been applied. And the resistance performance of the designed hull confirmed by numerical simulation. The numerical simulation is performed while changing the local shape of the goose neck depending on the bulb parameters. This study finds bulb parameters and their range that can affect the resistance performance. Thus, it is possible to provide a foundation to develop the optimal design technique and regression analysis on the resistance performance and goose neck bulb.

To prevent the Sewol incident again, by which the victims are 294 dead and still 10 missing, this study analyzed the change of safety consciousness of passengers onboard ship comparatively before and after the Sewol incident. The survey had performed 2 times at Jeju coastal cruise terminal at February 2014 and May 2014, and effective respondents were 394 and 401, respectively. After the Sewol incidents, the answers' ratio that they would follow the routes that the crews show and they would follow the crews' evacuation guides are decreased 24.5% and 18.5%, respectively. This means that the reliability on the crew members were decreased. Although 77.6% passengers responded that they felt nervousness onboard ship, 60% did not take safety lesson(s) and 45% did not know how to wear a life jacket. And also over 50% did not check the evacuation route map and the location of lifeboat, respectively. Meanwhile, 86.9% respondents answered the system of safey lesson should be changed, which has normally done by TV set.

According to the new rules and regulations (New SOLAS), major safety critical systems are to be designed to be redundant, which is called 'Redundancy Design'. This paper was to quantitatively analyze the degree of influence of the redundancy design applied to major safety critical systems using IMO's FSA(formal Safety Assessment) method. For the purpose of this study, the diesel engine system, which is actually one of major safety critical systems, was dealt with FMEA, FTA and ETA technique. In addition, whether the redundancy was met or not was verified and the degree of safety, or redundancy, was represented in terms of reliability. In conclusion, the safety of propulsion systems is possibly assessed systematically by estimating the risk level in terms of frequency and fatality.

Air pollution associated with the SOx emission from the shipboard propulsion and generation engines is becoming one of the major environmental concerns these days. Lead by the international organizations including IMO and European Union, a significantly strengthened air pollution related regulations have been introduced and they are becoming in practice as scheduled. Such rules are basically giving the guidelines for permissible SOx emission which can be only met by using high quality fuel oils with less sulfur content or operating scrubbing systems aiming at reducing SOx at the engine exhaust. Since both countermeasures can lead to the cost increase in ship building and operation, Korean shipbuilding industries, leading the world's market, need to be well aware of the ever changing regulations and be prepared with proper solutions. Here, we briefly summarize such latest rules and regulations on the air pollution at sea, and review some technical issues on the scrubbing systems available with some suggestions.
