The life cycle model of Mega Float: Floating offshore fishing terminal (FORT) for deep sea fishing industry is presented in this paper. FORT is a totally new concept of a mega float for deep sea fishing application. It is aimed at increasing productivity through reducing travelling time to fishing ground by providing critical support services such as loading and unloading and minor maintenance and repair of boat and equipment at sea close to the fishing ground. The immediate concern is surely on its life cycle cost and techno-economic viability. The system is huge and remotely located far offshore and hence the element of sustainability and environmental friendliness and safety are some of the major investment issues. Immediate cost consideration includes the relatively high initial/acquisition cost and operation and maintenance costs and the intention is to at least self-sufficient by generation income from the services offered. Therefore, hybrid algorithm of cash flow and life cost cycle is applied in FORT implementation. The new derivation of the mathematical model for FORT application is developed to life cycle assessment principle [1-3]. The algorithm requires data that could be best produced based on forecast demand and projected cost. For ease of use the lengthy algorithm will be presented in a computer-based package.

The research on the development of an innovative formula of a synthetic detergent with improved environmental properties, which meet the environmental standard of SOU OEM 08.002.12.065:2016 "Detergents and cleaning products. Environmental criteria for life cycle assessment" is carried out. The accumulated theoretical and practical experience is generalized, the general scheme of designing and development of new goods taking into account features of detergents with the improved ecological characteristics is created.
