Abstract

The tourist activities at Blue Beach are divided into 3 categories: swimming, water rides and fishing. The implementation of activities in the water poses a risk to tourists, which has the potential to cause accidents and even fatalities. This is due to the lack of segregation of areas for the implementation of the three beach tourism activities, which makes it difficult for tour managers to monitor tourists. For this reason, tour managers will be equipped with knowledge on the importance of dividing beach tourism activity areas based on bathymetric contours and the use of warning flags as safety signs for beach tourism activities. This socialisation can increase the awareness of tourism managers of potential hazards and disasters in the tourist sites they manage, by completing early warning signs of potential hazards of beach tourism activities. This socialisation is done in partnership with community-based tourism managers, namely Non-Governmental Organizations (NGO) of Tanjung Merdeka. The increase in knowledge and understanding of the socialisation material among the participants was 44.9 points. The service activity safety sign products were submitted by the service team in the form of a Blue Beach tourism activity map based on bathymetry contours and beach safety warning flags as occupational safety and health-based signs in the Blue Beach tourism area.

Abstract

The large deck openings of ultra-large container ships greatly reduce their torsional stiffness, and hydroelastic analysis is a must for reliable structural design. In the initial design stage, the beam model is a rational choice. This study aims to investigate torsion's effect on container ships' strength using a numerical approach based on fatigue boundary conditions and ultimate boundary conditions in the midship region. Regarding fatigue boundary conditions, the dimensional influence of the container ship is obtained at the connection between the longitudinal side shell stiffeners and the transverse web frame for nine structural details, which refer to different arrangements of reinforcing elements. The structural influence on the local stress distribution was assessed along the longitudinal plates between the regular stiffeners bounding the perimeter of the torsion box by calculating the hull girder stresses.

Abstract

The graving dock gate is one part of the graving dock construction. the construction of the graving dock gate that is directly facing the sea must be able to withstand the load from the water at all times. by making modifications to the Gate construction, the design results are obtained which are quite optimal in terms of weight strength. the redesign of the graving dock Gate pt.barokah galangan perkasa cannot be separated from a problem where the previous construction design was too heavy and exceeded the required laden. Causing the graving dock gate to not be able to float when the water conditions are low. The main size of the graving dock gate pt.barokah galangan perkasa is 3 meters long, 46 meters wide, 7.32 meters high. the method used in this redesign process is to use the e application of the finite element method ANSYS apdl, while 3d modeling uses SketchUp, and AutoCAD.

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.
