Technical report Test Resistance Test Sabang Marindo ship model

1. INTRODUCTIONTechnical report Test Resistance Test Sabang Marindo ship model is a report that describes the activities that have been carried out by the Leader Manufacturing and testing of ship models 1.2.0, Program Completion Application Design and Test Operation Fast Ferry Transport Passenger / Goods 2010.Numerically based assessment in the first year (2008) and second year (2009) has made the choice of vessels to be used as a model in this research is a fast ferry Marindo Sabang. Where the results of the numerical calculations is known that the ship Marindo Sabang has the highest stability ~ 75 degrees, and rolling angle <10 degrees.As a first step in this activity is 2010 on ship design improvements Marindo Sabang, which is done by doing paint smear testing and test resistance at Sabang Marindo ship model that was created in 2009.Test Resistance testing is done with a speed of 25 knots in the two conditions of the ship, which is testing resistance in the test conditions and the condition of the model evenkeel trim.2. PURPOSEThe purpose of this activity is malakukan testing resistance test on two conditions evenkeel and trim on a speed boat 25 kont. Where it is intended for prisoners to get the amount of information that occurs in the condition of the vessel evenkeel and trim.3. RESISTANCE TO TEST

 
Activities undertaken in the third year (year 2010) in the form of design modifications linesplan fast ferry passenger ship based on the analysis of numerical / mathematical models, test the model in the pool and a full-scale measurement of the performance of a fast ferry transport of goods and passengers.The results of technical studies in the previous 2 years so needs to be supplemented by performance data fast ferry while sailing in the sea. Thus in 2010 the research activities focused on the assessment results of the performance data collection fast ferry vessel operating on the high seas through a full-scale measurements (full scale measurement).Measurement data is analyzed and studied together with the results of hydrodynamic studies in the previous year and then made modifications to the design and re-test in order to obtain a hydrodynamic body shape design fast ferries are safe and comfortable for the passengers.Resistance testing performed on evenkeel conditions in Towing Tank with 2 m laden ship. In this test the ship's speed varies as follows: speed of 12.5 knots; 15 knots; 17.5 knots; 20 knots; 22.5 kont; 25 knots and 27.5 knots.

 Resistance testing performed on the trim condition 2 condition trim, trim back the 2 cm scale models and trim back 5 cm scale models. The test is performed on each Towing Tank with boat speed varies as follows: speed of 12.5 knots; 15 knots; 17.5 knots; 20 knots; 22.5 kont; 25 knots and 27.5 knots.Results of testing the resistance test trim conditions shown in graphic form the relationship between the resistance vessels and speed boats.
 

Resistance testing conditions of the model trim back 2 cm and 5 cm with a speed of 12.5 knots variations; 15 knots; 17.5 knots; 20 knots; 22.5 kont; 25 knots and 27.5 knots, the results are displayed in graphical form relationships resistance ship with a speed
