Abstract

Difficulties to obtain good wooden materials as vessels primary materials conduce to drop the quality and the lifetime of a ship. To satisfy new ship building demand, a shipyard tends to apply fast building and ignores the ship quality, types, and dimension and materials characteristics. Shipyard also did not consider about the technical and operational aspects as rule and regulations for wooden vessels. Un-optimal ship construction make it low in quality and at the end, it cannot be used directly after handover. In general, the cause of damage of ship was due to unsatisfying of construction criteria such as the types of wood, including the age and the length of the wood used for its construction. In addition, it had been found that there were unsatisfied ships operating under construction regulation.

Abstract

The power requirement of ship must comply its form and principle dimension to make efficient fishing operational cost. To estimate power requirement of a ship conducted by vary approach such as Guldhamer Methods. Manual calculation by using this methods somewhat sophisticated and not practical since can only be done by certain people. Thus, to make it more simple, all the patterns are modified to be Matlab Graphical User Interface. The result shows that scoop netter power is 25,0754 HP calculated by using Matlab Application, meanwhile in the real condition the magnitude of fisher fishing vessel is 26 HP. There was discrepancy approximately about 4% where it was caused by measurement calculation in the field. Thus, this application can be used as a reference in calculation power requirement of a fishing vessel.

Abstract

A good designer of fishing vessels must be able to estimate ship resistances which treat-ment on ship during fishing operations. Such resistances information will be used as themilestones in the main and the auxiliary engine matching in which the chosen engine must besuitable to the needs of thrust at the certain velocity. The magnitude of ship resistance can bedetermined by some methods e.g. towing tank methods, using ship resistance graph of seriesship models on various velocities, using approaching formula from statistic (with regression)and the last by using Computational Fluid Dynamics (CFD). CFD is the most economic inship resistance study with result almost approaching the manual test. The ship was gillnetter 5in gross tonnage. Its model was investigated by using numerical simulation of CFD. The dataof resistance are processed with ANSYS CFX version 14. The result shows the vesselresistance was 6,43 kN and engine power was 29,76 kW at maximum speed (9 knots). Itimplys the similiar conclusion by using manual test and approaching formula.

Abstract

Abstract This research was conducted to measure the level of productivity in ship repair activities and determine the factors that influence the increase in productivity in ship repair activities. This research was carried out in April until May 2018 at the shipyard of the Palabuhanratu Fishing Port, Sukabumi Regency, West Java Province. The method used is a survey method by knowing directly the productivity of reparations in shipyards. Reparation is an overall activity about repairing a ship, starting from the collision on the part of the ship that is leaking, painting, replacing weathered wood, cleaning the hull skin and repairing the damaged engine. Productivity is a comparison between spending and input. The factors that most influence the shipyard productivity from the measured performance indicators are the number of employee absenteeism or labor where the importance of the weight is 30%, the ship repair workforce and effective working hours which have a weighting of 20% each. Based on the results of the measurement of performance indicators for 5 years with the Objective Matrix method, the productivity index of performance indicators from 2013 to 2017 has experienced a considerable decline due to the decreasing number of vessels carrying out ship repairs. Keywords: Ship Repair, Productivity, Measurement of Performance Indicators
