“…The gas temperature did not determine the temperature of the exposed steel because of the effects of radiation and convection. Thus, a heat transfer analysis needed to be carried out to identify the steel temperature while considering the effects of radiation and convection (Kim et al, 2013). = 25 W/m 2 K, and the emissivity of carbon steel was ε s = 0.7 (Franssen and Real, 2010).…”

Current industrial practices and approaches are simplified and do not describe the actual behavior of plated elements of offshore topside structures for safety design due to fires. Therefore, it is better to make up for the defective methods with integrated fire safety design methods based on fire resistance characteristics such as residual strength capacity. This study numerically investigates the residual strength of steel stiffened panels exposed to hydrocarbon jet fire. A series of nonlinear finite element analyses (FEAs) were carried out with varying probabilistic selected exposures in terms of the jet fire location, side, area, and duration. These were used to assess the effects of exposed fire on the residual strength of a steel stiffened panel on a ship-shaped offshore structure. A probabilistic approach with a feasible fire location was used to determine credible fire scenarios in association with thermal structural responses. Heat transfer analysis was performed to obtain the steel temperature, and then the residual strength was obtained for the credible fire scenarios under compressive axial loading using nonlinear FEA code. The results were used to derive closed-form expressions to predict the residual strength of steel stiffened panels with various exposure to jet fire characteristics. The results could be used to assess the sustainability of structures at risk of exposure to fire accidents in offshore installations.

“…Therefore, measures to maintain the structure against fire are required. Epoxy-based paint applied to the surface of the structure is a general measure of passive fire protection (PFP), and research on the effect of the application has been conducted (Ahmad, et al, 2013;Friebe et al, 2014;Kim et al, 2013). However, since PFP application should take time and cost efficiency into account, this study examined the structural stability and efficiency from the PFP application.…”

Explosions and fires on offshore drilling units and process plants, which cause loss of life and environmental damage, have been studied extensively. However, research on drilling units increased only after the 2010 Deepwater Horizon accident in the Gulf of Mexico. A major reason for explosions and fires on a drilling unit is blowout, which is caused by a failure to control the high temperatures and pressures upstream of the offshore underwater well. The area susceptible to explosion and fire due to blowout is the drill floor, which supports the main drilling system. Structural instability and collapse of the drill floor can threaten the structural integrity of the entire unit. This study simulates the behavior of fire subsequent to blowout and assesses the thermal load. A heat transfer structure analysis of the drill floor was carried out using the assessed thermal load, and the risk was noted. In order to maintain the structural integrity of the drill floor, passive fire protection of certain areas was recommended.

“…While this wider safety research does not directly relate to fire safety in machinery spaces, its application may provide holistic improvements in fire safety in ships, which would ultimately include the machinery spaces. This systematic approach to accident prevention is not at the expense of analysis of individual features of fire prevention however and can be noted in the literature covering human and organisational factors, historical causal factors of fires in maritime transportation, calculation of fire probability (25)(26)(27), along with fire impact analysis research focusing on mitigating the outbreak of fire (28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40)(41).…”

The primary cause of machinery space fires is cited as the release of flammable oil mist contacting unprotected hot surfaces. With this being common knowledge why do we continue to see this type of incident reoccurring on ships carrying thousands of passengers to precarious destinations? We review regulatory and Class requirements with respect to fire safety, Formal Safety Assessment (FSA) as a rule-making instrument of the IMO, accident investigation recommendations involving fire, fire safety technology, and research literature. For each constituent of fire safety control, the paper aims to determine the preferred strategies for accident prevention and their relative cost effectiveness. Subsequently, the cost effectiveness of the current safety approach is established. This review found that fire prevention could be made more cost effective if its scope was broadened beyond the detection of proximate events occurring immediately before ignition. The findings suggest that more cost-effective safety measures can be developed by addressing systemic causes of fire. Removal of the systemic causal factors of fire from the equation, means we can address fire safety prior to the moments before ignition when the point of no return can unwittingly be passed. The paper suggests directions of how this can be achieved.
