The winds of change are blowing in the maritime industry as it charts a course towards a greener future. The Energy Efficiency Existing Ship Index (EEXI) regulation is leading the charge, and one of the key tools in achieving compliance is optimized propeller design. In this article, we will delve into the importance of optimized…
Many of you might have often heard the discussion between Master, Chief officer and Chief Engineer with regard to vessel propeller immersion issues, due uneven load of cargo, lack of cargo or impossibility of ballasting/de-ballasting the vessel due shear forces or bending moments. This is a very serious issue as propeller immersion less than 100%…
Modern massive two-stroke marine engines with fixed pitch propellers that are directly connected must be reversed, that is, the engine’s rotational direction must be changed to drive the ship ahead and astern. This is generally necessary during ship maneuvering, such as berthing, passing through canals, lock gates, and anchoring, among other things. I have received…
