A concept study for fixed carbon dioxide fire-fighting system basis internal buoyancy control air-bag system for damaged ships

Abstract

Though the number of marine accidents has gradually decreased, fatal ones still occur. To prevent huge losses of both life and property, many technical solutions have been introduced. Notably, airbag.systems are researched and developed for maintaining the essential buoyancy of damaged ships. However, many outer hull basis airbag systems that have been introduced are too big and not feasible. This is because they require additional huge and expensive.systems such as storage boxes and gas injection.systems. In addition, the maintenance of outer hull basis airbag.systems is difficult. In the case of inner hull basis airbag systems, the complicated geometrical shape of the inner space and the requirements of additional systems such as gas infection.system are the barriers. For this reason, in this paper, thousands of real ship basis damage scenarios are researched. Furthermore, to mitigate the consequence of the damage and to minimize the requirements of the additional systems for the airbag systems, carbon dioxide firefighting system basis 3-dimensional airbag systems have been conceptually designed. By using existing fire-fighting systems for gas injection and point cloud data of inner ship space for complicated airbag shape, the suggested airbag system has applicability in both new and existing ships with minimum requirements of cost and remodeling.
