Abstract

The objective of this research is to design a catamaran tourist ship that incorporates green technology. To achieve this, the main dimensions of the ship will be determined using the linear regression method, based on existing data from similar vessels. The empirical data from existing vessels serves as the foundation for the analysis and prediction, thereby enabling the identification of relationships and patterns between the key variables, including length, width, draft, displacement, and passenger capacity. The linear regression method offers several advantages, including simplicity, ease of interpretation, and efficiency in the use of resources. As a result, it is an effective tool for initial analysis before the application of more complex methods. The R2 value has an average result above 90 percent, so the data can be considered good and valid. The innovative aspect of the design of this tourist ship is the utilisation of data pertaining to existing vessels that have demonstrated optimal performance in their role as tourist ships. The use of existing data not only helps reduce the risk of errors in the design of new vessels but also ensures that the design is efficient and compliant with operational needs and safety regulations. This research confirms the importance of a data-driven approach in the design of environmentally friendly and efficient ships. In the context of ship design and operation, displacement represents a pivotal parameter in linear regression analysis. An understanding of the relationship between displacement and ship performance allows for more accurate predictions regarding speed, fuel consumption, stability, and draft. This allows for the design of ships that are more efficient, stable, and safe, and optimized under a variety of operational conditions.

Abstract

In general, molding or FRP ship molds can only produce 1 (one) hull shape. This is of course, contrary to the production of ships which are mostly of the customize type (based on consumer demand) and very rarely in the form of mass products to produce sister ships. The high cost in the allocation of molding certainly makes economic considerations regarding the cost of shipbuilding. With the aim of a friendly fishing boat price, of course, it can make a mainstay and ease the burden on the answer to the high demand for fishing boats in the coastal community or the South Coast of Java. Multi-mold is a ship molding solution for FRP ship material that can produce more than one hull shape. This of course, will reduce the cost of producing a ship or boat. The cost budget plan is determined in detail through a survey of material prices and conducting a price determination study with an engineering estimate approach. In the multi-mold system or components, there are the main shell structure, reinforcement frame and suppot or mold holder. The shape of the multi-mold is carefully designed which can be knocked down each constituent component. The multi-mold disassembly process is accompanied by operational instructions and 3D simulation of the multi-mold assembly. The structural strength of the multi-mold components is also analyzed so that an effective and efficient multi-mold design is obtained.
