Propeller Selection and Design
The correct selection of the gearbox and propeller propulsion system ensures maximum efficiency of a vessel and increases the durability of the system components such as engine, gearbox, bearings, etc.
This selection requires specialized calculations to be performed professionally.
TECNAVIN S.A. by resistance calculations, vessel type, duty cycle, engine , can reliably determine the best working conditions for each vessel, ensuring the best performance by selecting the propeller characteristics required for that ship or performing entirely propeller design to be built to meet the requirements of Classification Societies.
ESPECIAL CALCULATIONS
Exhaust gas system backpressure Calculation & Muffler Design
Pressure loss calculation on exhaust gas circuit including the muffler to check the permissible limit for adequate operation given by the engine manufacturer.
Confort and insulation: noise calculation
•Noise transmission calculation across different ship compartments
•Adequate Acoustic & SOLAS thermal insulation Estimation on each ambience to satisfy the noise and comfort regulations establish by Classification Societies
Circuit Calculation
Power pump estimation by the head Loss Calculation for fresh & sea water, fire circuit, etc.
Inclining test and stability booklet
•Tecnavin S.A. can do inclining test and stability analysis for all types of vessels, provided IMO guidelines to ensure a successful test.
•The stability study is based on the inclining test to establish the correct center of gravity of the ship and to make the stability study to check whether the requirements set by regulatory entities for each type of vessel are met.
