Abstract

Abstract: Plates are a very important part of shipbuilding and offshore structures. The reinforced plate is used to withstand loads acting in the axial and bending directions. The structure of the deck or bottom plate exhibits buckling or yielding behavior. Thus, it is very important to analyze the ultimate bearing capacity of a plate structure subjected to compressive loads for safe ship structure design. The material configuration used is the most important aspect in the FPSO structure design criteria. Plates and stiffened plates experience local buckling due to the external load when the hull girder collapsed. The objective of the present study is to analyze the effect of flange and web thickness to the ultimate strength on the FPSO in terms of plate deformation located of the bottom and deck area under compression stages. In this study, the attached plate thickness is varied according to FPSO data and BKI Rule. The stiffened plates element located at the bottom and deck area are modelled by Tee-Bar and Angle-Bar element. The simply supported condition is applied to the model and the anon-liniear Finite Element Method is used for the analysis. The result obtained by NLFEM shows that under tension and compression, the stiffened plate of Tee-Bar model, the deformations are 1,75 mm and 1,8 mm respectively. While for Angle-Bar model the deformation are 12,4 mm and 13 mm under compressing respectively.

Abstract

Indonesia is one of 193 countries committed to the sustainable development goals (SDGs). In this new paradigm of sustainable Indonesian development, the maritime sector is a priority for future development with the concept of blue economy, which is a sustainable ocean economy that produces economic and social benefits with the assurance of long-term environmental sustainability. The focus of the blue economy with this maritime economic strategy makes coastal communities the centre of blue economy growth. Makassar City has a coastal tourism area located in Tanjung Merdeka Village, Tamalate District Makassar, and is managed community-based by Non-Governmental Organizations (NGO) of Tanjung Merdeka. To maintain the sustainability process of coastal tourism area management, it is necessary to understand the concept of blue economy according to the maritime development strategy. Socialisation of the concept of blue economy in the development of coastal tourism areas in Makassar City has been carried out and achieved an increase in knowledge and understanding of participants by 50%. Understanding the concept of sustainable coastal and marine resource management, as well as how to participate in facing the challenges of environmental degradation and climate change, will complement the role of Tanjung Merdeka NGO as a tourism manager with the concept of blue economy. Assessment of the application of the concept of blue economy in coastal tourism areas has been carried out and fulfils the concept of blue economy according to Pauli's theory (2010).
