| description | Nowadays,
the issue of energy efficiency in the maritime transportation sector has been
strongly associated with the decreasing use of fossil energy and greenhouse gas
emissions. Crew boats are one of the ship modes which consumes a lot of fuel in
maritime transportation. This affects the number of exhaust gases released into
the atmosphere. A study into the estimation of crew boat resistance was carried
out experimentally using a towing tank, numerically using a CFD methodology,
and then compared with Savitsky's method. Measurements were taken in calm
waters under even keel and trim scenarios, considering load variation had been
adjusted for. Determining the correct load position affected the LCG
(Longitudinal Center of Gravity) and VCG
(Vertical Center of Gravity)
parameters, affected trim, and decreased crew boat resistance. Overall
results showed that the experimental test, CFD method, and the empirical
estimation from Savitsky were in good agreement with average errors up to 3%.
The calculation results demonstrated that trim had a greater influence on
decreasing resistance up to 3.062% than even keel position. Furthermore, the
shifting of LCG had a more significant effect than that of VCG in the context
of resistance changes. |
