Student’s report is to be submitted on-line (PDF files)   __________________________________________________________________________________  Hydrostatic Analysis (25%)  The offset table of 88.2m bulk carrier is provided, and the main particulars of the ship are as follows:  LWL (St.0-15) 84 m  BWL (Max) 15.27 m  Displacement 4206 t  KB 2.055m  KG 5.88 m  LCG 45.2 m  T 3.91 m 1. Using the offset table and associated data, determine the best estimates for the following hull  form data at the ship’s design draft (3.91m):  BMT,  KMT,  BML,  KML,  LCF,  TPC  and  MCTC 2. Draw a GZ curve using the cross-curve given in the 2nd page of the excel offset table, where  formulas and GZ table is provided. Investigate if the ship stability complies with the “Criteria for  the righting lever curve properties”, sub-section 2.2 of International Code on Intact Stability, 2008  (IS Code). The IS Code is accessible through IMO Codes from Regs4ships website:  (http://dmr.regs4ships.com/australia/)  (continue next page)  __________________________________________________________________________________  http://dmr.regs4ships.com/australia/ JEE 504 – Principles of Naval Architecture – Assignment  __________________________________________________________________________________  2    Interpretations Required of Students:  Provide a concise assessment of the vessel’s probable sensitivities to GZ curve if additional loads are  either loaded to or discharged from the vessel during port operation, based on any of the values you  have determined above. Guidance for Students:    An approach recommended to this part of the project is as follows:   1. Set up a spreadsheet to determine the values required similar to Assignment-1  2. Refer to page two of the excel sheet and read out the GZ values for the given displacement.  3. Correct the extracted GZ value for the given KG since the default value for the GZ table is 6m and  complete the GZ table using two formulas given.  4. Draw the GZ curve and check if it complies with the Righting-Lever criteria given in IS-Code. You  may need to measure the area under the curve using Simpson’s rules.  ________________________________________    Syllabus 14 template 1  Dr Hossein Enshaei JEE504 Principles of Naval Architecture:  Final assignment-part2  Motion response in an irregular sea Analysis Due Date: June 12th, 2023. This assignment forms 25% of the subject's total marks. Synopsis of the task and its context  Students individually develop a software package to calculate motion response spectrum using experimental data collected for 1:20 scale  model ship (Bluefin) at AMC towing tank. The model is operating in head sea at 1 m wave height at 8 knots (0.05 m @ 0.92m/s model scale).  This is using the constant wave height, varying wave freq data and then by adding the final three runs at varying wave height with constant  frequency. There is an Excel file attached to this assignment that provides the ship's particular and the experimental data. For model scaling  refer to the references. 1- Plot the required spectrum and RAO using variable input parameters collected at different experimental runs 2- Calculate the motion response parameters such as spectral moments, mean response period (frequency), significant response amplitude and maximum amplitude in each of the given motions. 3- A review should be conducted in a form of a report to demonstrate the knowledge and understanding by discussing the linearity of the seakeeping behaviour of Bluefin.

offset table of a model ship. 		In order to convert it to a ship scale, you need to calculate the scale factor by dividing the half of the ship's beam (15.27/2) by the half of the model's beam (0.092). 		This scale factor (83) should be multiplied to the above offset table to get the ship's offset table.  		For the sake of simplification, the forward part of the ship is excluded from the offset table where there are more complications.  Cross Curve 																			Roll Angle (Deg.)
