Optimal Hull Form Development / Design
Our Think Tank Headquarters utilizes 3-D Hull design systems that take into consideration hull form production and modification to provide efficient and variegated in-house designs for all types of vessels, ranging from commercial to special purpose vessels. Therefore, we possess a diverse portfolio of hull form case studies as reference for drag force optimization.
Hull Form Production
Hull Form Modification
Hull Form Performance Analysis and Optimization
Our Think Tank Headquarters applies CFD data acquired through Star-CCM+ to analyze hull performance in resistance and self-propulsion and implements the ITTC analytical method to predict vessel speed and horsepower. In addition, we study and analyze the flow field and pressure distribution on the surface of the hull, as well as fluid waveform and wake distribution in order to best reflect the improvements to subsequent hull form design and optimization.
Analysis of Resistance Performance
Analysis of Self-Propulsion Performance
Development/Design of Optimal Propulsion Systems
Our Think Tank Headquarters designs Propellers in accordance with the KRISCO Propeller Design Code, and implements STAR-CCM+ to qualitatively evaluate and analyze cavitation effects on designed propellers, conduct research on various forms of cavitation, as well as estimate the risks of propeller erosion through said cavitation in order to best optimize vessel propulsion design.

Performance Evaluation through Scaled Model Trials
The Think Tank Headquarters implements all tasks relating to the final performance evaluations and scaled model trials of developed hull forms and subsequent propulsion systems as outlined below.
- Review suitability of trial institute (Equipment, Facility, Performance, Personnel, etc.)
- Review trial contract and execution schedule.
- Compile and provide appropriate data for model trial
- Delineate and review Test Scope of Model Trial
- Scrutinize specifications and fidelity of Stock Propellers to be used in Model Trials
- Confirm application of ITTC recommended values during trial (fluid temperature, mass, kinematic viscosity)
- Examine correlation and accuracy between trial values (speed, horsepower, RPM Margin, self-propulsion) and estimates of said values conducted prior to trials.
- Appraise validity of measurement methods and acquired data during wake measurement and hull streamline trials.
- Examine trial result report for proper consideration and implementation of provided vessel specifications and hydrodynamic data.
- Review adequacy of estimated effective vs. delivered horsepower.
- Analyze various resultant values in drag and propulsion.
- Review whether estimates of drag and speed were accurate based on the ITTC 1978 analytical method.
- Determine and present satisfaction of contract-specified speed.
