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 research was conducted on July to October with goal to obtain gilnetter performa in Maskom Village, District of Bengkalis through vessel response toward beam sea, following sea, and head sea. The vessel faces oscilatory motion in 6 degree of freedom. The vessel model was optimizing vessel in previous research. The principal dimension is LBP 14,0 m; B 2,8 m; H 2,4 m and T 1 m. It was modelled by using Maxsurf and continued using Seakeeper to ana-lyze Response Amplitude Operator (RAO) for instance pitching, rolling and heaving motion. Input data as vessel speed, feading angle and spectrum type was entered to depicts vessel re-sponse information. RAO for pithcing, rolling and heaving is between 1,1-8 and encountering frequency is in 0,22-0,6. It can be concluded that the vessel are decent to operate in the sea (seaworthies).

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

Accuration for preparing budget to estimate contruction costs greatly affects thesuccess of its funding. In addition, this will effect the successfull of its building. Inboatbuilding project, this will monitor the initial funding ability. Therefore,preparation of Cost –Budget Plan (RAB) can be as a solution to describe total cost inboatbuilding as material cost, cost of manpower, etc. The aim of this research is togenerate application of RAB for Bagansiapi-api shipyard by using Macros Excel. It isdeveloped by using prototype methods with visual basic for application (VBA).Results shown that the resulting aplication can help in processing the boatbuildingcost .

Abstract

This research was conducted in December 2012 with tuna longliner as the objectin which designed operated in Bungus Waters, Province of West Sumatera. The objectof the research was the review of previous reseach with optimatized main dimensionnamely LWL = 29,27 m, LPP = 28,14 m, B =6,40 m, H = 3,57 m dan T = 2,87 m. Theaim of this research is to calculate tuna longliner stability by inputting main dimension,form coefficients, and various other additional paramaters. Its value was entered toequations of stability calculation so that resulting a value that will be checked its statustowards stability criterion according to IMO. Calculation result conclude that tunalongliner stability satisfy IMO criterions.
