In this post I have discussed the questions that were asked in the Class 4B exam of MMD exam. This is the part 1 of series dealing with the Marine engineering practice. Answer to these questions will be available shortly. It is very important to have a look of the questions that are asked in the previous year’s exam papers. If […]
Parametric rolling in container ships is a phenomenon that can cause extreme and dangerous roll motions in head or stern seas. It occurs when the natural roll frequency of the ship coincides with the frequency of wave-induced changes in stability, resulting in a resonance effect that amplifies the roll angle. Parametric rolling is more likely […]
Fresh water generator as name suggest is an machinery onboard which is used to generate fresh water for various purposes like drinking, washing etc. An engineer should know as how to operate this machinery effectively as water is a crucial fluid onboard. This machinery uses the principal of evaporation of water at lesser temperature if done so in low pressure […]
