Scale Of Operation

There is an overwhelming support to move aquaculture cages into offshore waters. Some of the key drivers for moving into offshore waters are limitation of available space near the coast, conflicts within as well as other coastal users, prospect of limitless expansion in offshore sites, the potential for optimum growth conditions and the need to reduce the production cost by increasing the scale of operation. Therefore, by using a set of requirements derived earlier by the authors, the paper looks into the current offshore cage designing concepts in order to propose an optimum design concept for offshore aquaculture. With the help of an expert panel, representing various disciplines which are important for fish farm development, the assessment point towards a single point mooring cage concept as the best option for offshore aquaculture farming. This concept is demonstrated by the use of simple geometric relations and graphs, showing the relation between the total horizontal forces, FH, vertical force component, FV, as the cage submerge. While the contribution from the current, FHC, to the total horizontal force, FH, is kept constant, the contribution from the waves to the total horizontal force, FH, (as assumed to be 33%) is subjected to a reduction proportional to the factor e2kz, representing the reduction in water particle velocity as a function of depth. Further, in light of the requirements derived through the major stakeholders, this paper also propose an alternative classification of cages into two major categories, i.e. systems that are intended to resist and dissipate environmental forces and system that are designed to avoid environmental forces.

Ocean Thermal Energy

This paper describes the thermo-fluid design concept of a low-pressure, radial inflow steam turbine for the Open-Cycle Ocean Thermal Energy Conversion (OTEC). For the optimum design consideration, the necessary theoretical tools are developed. The design concept permits the utilization of single-stage and multistage configurations for small and medium power ranges, respectively.

The Relationship

The relationship of contact width and leakage had been found as design concept to optimize new metal gasket. By using this design concept, the limits of contact width for no leakage can be chosen. The optimize gasket shape can be developed by increasing of contact width. In this study, a gasket shape was optimized based on contact width as design concept and involving contact stress consideration. The design of experimentation (DOE) Taguchi method is used to analyses the effect of each parameter design and predict optimal design of new 25A metal gasket. The L18 orthogonal array was concerned to design experimental matrix for seven factors with three levels. The optimum design of gasket at 0 MPa mode is the model with OH = 4 mm, p1 = 3.5 mm, p2 = 4 mm, p3 = 4 mm, t = 1.2 mm, R = 3.5 mm and h = 0.4 mm. The optimum design of gasket at 400 MPa mode is the model with OH = 3 mm, p1 = 3.5 mm, p2 = 4.5 mm, p3 = 4.5 mm, t = 1.8 mm, R = 1.5 mm and h = 0.3 mm.

Ratu harbor beach is one of the mainstay tourist sites for the Regional Government of Sukabumi Regency in bringing PAD, besides public transportation facilities and terminals have a major role in supporting the queen port as a tourist attraction so that tourists are comfortable and facilitated in accessing through public transportation. The condition of the Pelabuhan Ratu Terminal, Sukabumi Regency is currently very poor, poorly maintained, and many supporting facilities are damaged and inadequate. This study aims to identify problems and formulate the type B terminal arrangement in Sukabumi Regency. The method used is descriptive qualitative in order to get a picture of the problems of the situation and conditions currently taking place or occurring in the present and the study of policies. Collecting data by field surveys, literature studies and interviews. The results in this study get a terminal B type terminal design concept Sukabumi Regency according to current and future needs.
