Abstract

Indonesia's geographical conditions and position are very favorable and various policies from the government from 2005 until now are expected to become the shipyard industry to become a tough industry, but in reality it is still not as expected. The condition of the domestic shipyard industry in 2017 until now there is only ship repair and maintenance work, while orders for new ships or buildings are very few and even zero demand ship orders, causing business continuity in the shipyard industry to be disrupted and even out of business. This paper aims to develop a concept for the development of a multi-oriented shipyard industry that is environmentally friendly and sustainable. The preparation of this concept begins with identifying problems, collecting secondary data, reviewing related articles (shipyard industry, ship recycling yard industry, environment, sustainability, and supporting methods), analyzing and developing a development concept. The results obtained from drafting the concept are in the form of a diagrammatic model for the development of a multi-oriented shipyard industry that is environmentally friendly and sustainable. The development concept consists of (1) research background in the form of the existing conditions of the shipyard industry, ship recycling industry, geography, infrastructure, superstructure; (2) research that has been conducted in the form of relevant journal articles and proceedings; (3) research to be conducted in the form of sustainability criteria, orientation diversification and strategy selection; (4) implementation.

Abstract

An investigation into the hydrodynamic force and seakeeping of single-to-twin after ship hull (STASH) and multi-hull geometry was done successfully. STASH is characterized by its monohull-shaped design in the fore part and twin hull in the rear part creating unique performance, especially seakeeping which being the focus study to provide seaworthiness. The method of accomplishing this study was through computer simulation using Maxsurf: Motion for seakeeping and hydrodynamic force analysis. The overall results were compared with published data and mathematical models for validation purposes. The results are believed to be useful for the development of the ship design and performance.
