For the safe design of the offshore plant, it is necessary to evaluate not only the marine environment of the offshore plant installation area but also extreme conditions such as fire and explosion. For the safe evacuation of crews in danger of fire and explosion, the offshore plant requires an exclusive escape facility. Passive Fire Protection (PFP) is widely used as one of such facilities. In order to realize the reasonable structural design of PFP, evaluation of structural strength based on offshore design code considering various loadings from fire, explosion marine environment. In this study, structural design was evaluated by using code check and heat transfer analysis to verify the structural design of PFP for an offshore plant that can be installed in the North Sea area. The three - dimensional finite element analysis model of PFP was created and the results of structural stress and deformation were derived using finite element analysis by applying the load conditions. The structural analysis results were evaluated for strength of all structural members of PFP by interfacing with code check program. Heat transfer analysis of PFP was carried out to investigate fire-proofing characteristics against fire accidents. The design integrity of PFP was evaluated from the results of strength evaluation and heat transfer characteristics of structural members.

Recently, domestic leisure boats have been actively researching eco-friendly product development to enter the global market. Since the hulls of existing leisure boats are mainly made of fiber reinforced plastic (FRP) or aluminum, design techniques for securing structural safety by applying related materials have been mainly studied. In this study, an initial structural design safety assessment of a trimaran pontoon leisure boat with a modular hull structure and eco-friendly high-density polyethylene (HDPE) material was conducted, and sensitivity evaluation and optimization analysis for lightweight design were performed. The initial structural design safety assessment was carried out by creating a finite element analysis model and applying the loading conditions specified in the ship classification regulation to check whether the specified allowable stresses are satisfied. For the sensitivity evaluation, the influence of stress and weight of each hull structural member was evaluated using the orthogonal array design of experiments method, and an approximate model based on the response surface method was generated using the results of the design of experiments. The optimization analysis set the thickness of the hull structural members as the design variable and considered the optimal design formulation to minimize the weight while satisfying the allowable stress. The algorithm of the optimization analysis applied the Gradient-population Based Optimizer (GBO) to improve the accuracy of the optimal solution convergence while reducing the numerical cost. Through this study, the optimal design of a newly developed eco-friendly trimaran pontoon leisure boat with a weight reduction of 10% was presented.
