Norwegian Continental Shelf(NCS) is known as rich oil & gas reservoir and takes one third(1/3) of total continental shelf of Europe.(As of year 2013, Norway ranked third in the world in terms of exporting natural gas.) Until recent low oil price stream, development of oil & gas in NCS was active and perceived as profitable business. This paper describes study of living quarter fire protection for PSA AoC to prepare for likely increasing demands of offshore projects in NCS field.

When design the crew's living quarter, it is very important to consider the comfort for crew as well as its function. In this paper, design concepts of crew's living quarter are investigated based upon the questionnaire survey and the respondents who have been experienced going on board . Also, some improvements for interior design of the merchant ship are presented.

Global Energy Industry's high oil prices persist while their petroleum and gas production areas are entering the decline phase. More and more the drilling facilities used to bore oil from deeper depths are advancing further out into the oceans, which cause the development of "OFFSHORE" ship manufacturer facility's production demands to increase. The "OFFSHORE" ships provide a living space or L.Q (Living Quarters) for crewmen who work on the water far away from any mainland for extended periods of time. This research analyzes the LQ areas and the characterization of interior designs of different types of "OFFSHORE" ships that were built in South Korea. Also using overseas countries' Classification Society, known as "NORSOK," and analyzing their own design guidelines in conjunction with the research, the process of interior design and baseline data research was used to blueprint the new LQ areas. According to the results of the research, where ships get comprised of characteristics and operations by standards of the Classification Society's RULE, has the greatest effect on the design and design method of the LQ area. The research also shows that a conservative shipbuilding market of the Shipbuilding Company and ship owners' feelings are steadily changing to more open mindedness of acceptance. Therefore, the Korean Classification Society has to provide the new design principle to correspond to the international regulations and more various interior design plans of LQ areas needed to be present based on the new design guidelines. The capacity of the South Korean OFFSHORE shipbuilding industry is the world's top leader; however, the interior design of the LQ areas are still based from outdated designs from the 1980's. Hopefully these research results will be the cornerstone to help the shift from the outdated designs of the LQ areas to more practical modern designs.

The purpose of this study was to identify general characteristics of social lifespaces in Korean family houses and to investigate the changes in the physical aspects and room functions of social lifespaces from Yi-dynasty to the present. The documentary research method was used for this study. Total of 972 out of 1,109 floor plans were analyzed for this study. The major findings were that changes of social lifespaces from Yi-dynasty to the present have been affected by natural and socio-cultural environments. The changes in the physical aspects of social lifespaces have shown from one or two social lifespaces to various single-purpose social lifespaces such as living room, family room, drawing room, and study room. In the past, the cnetral social lifespaces, Anbang(women's quarter) was larger than the living room/Daechung(wooden floor) but the living room in the present has become a central social lifespaces and larger. The room function of Anbang has changed from multi-purpose space to private space. Living room/Daechung had used as a pathway rather than a social lifespaces in the past but the living room has played many fuctional roles of family social activities in the present. The kitchen has also begun to use as a social lifespace. This is a new symptom that kitchen and dining spaces will be included as a new social lifespaces.

The purpose of this study was to investigate the middle-aged housewive's background characteristics influencing on the preference of elderly housing, depending on four aging-situations. The characteristics of the elderly housing dealt in thes study were geographical location. specially planned feature for the elderly, house type, the size of housing, housemate, the distance from the living quarter of their children, and whether they want to live in the rental house. The subject were 526 middle-aged housewives from middle-income householde living in the capital area. Questionnaires were sent through mail to the householde which tesponded positively on the information brochure about this study sent before. The characteristics of the elderly housing which perferred to was influenced by their age and socio-economic status, such as schooling, job, income, and the size of housing. This result suggests that it must be considered to develop various types of the elderly housing depending on socio-economic status.

Welding often results in welding distortion during the assembly process. The welding distortion of thin-plate structures such as the living quarters of ships and offshore installations is a more significant problem than in the case of thick-plate structures. Pre-stressing/heating and fairing, which are additional works to mitigate and control welding distortion, are inevitable, and the construction planning is accordingly delayed. In order to prevent welding distortion and minimize the additional work during the assembly process, increasing the plate thickness and/or the number of stiffeners may be a simple solution, but it may give rise to problems related to cost and weight. In this study, the welding distortion control effect of the type of stiffeners on the door openings of various living quarter structures was investigated using an experimental method and a finite element method. The results showed the feasibility of mitigating and controlling the welding distortion, and the optimum selection of the type of stiffeners was confirmed.

This paper presents on the evaluation of thermal comfort in office on offshore. In living quarter of offshore, strict air conditioning performance is required to office on offshore and displacement ventilation is applied to office space which rooms are required to confirm the thermal environment. The computational fluid dynamics (CFD) is performed to calculate the temperature, air velocity in office and thermal comfort such as PPM & PPD is evaluated by the CFD result.

Unit cabin means room, which is installed in the high value ship such as drill ship and FPSO, after pre-assembled. In order to develop the noise control design for a unit cabin, a variety of acoustic tests such as sound absorption, transmission, and radiated noise measurements were carried out by using the mock-up of living quarter. From the tests, it was found out that the combined noise level of a unit cabin could be dominated by the radiated noise from wall panel in low frequency range and the design guidelines for the noise control of unit cabin were fully established, such as the improvement of sound transmission loss between the cabin and corridor, and radiated cabin noise reduction.

Currently, the sprinkler method is widely used as an initial suppression method in existing firefighting systems. However, this method can cause significant damage to both equipment and facilities in the hydration area. To minimize this damage, fire extinguishing monitors are being developed that can spray fire extinguishing water directly at the point of fire. These monitors are installed on the top floor of the ship, such as the Living Quarter and Ventilation System. While conventional fire extinguishing monitors focus on lightweight research with a short spray port and require a spray distance of about 40 to 45m, recent developments necessitate a longer spray port, similar to a water cannon, requiring a spray distance of about 70 to 75m. This study aims to predict the injection distance of both the existing ship-installed fire extinguisher and the long spray port fire extinguisher through hydrodynamic computer analysis, and to determine whether the injection distance has increased.
