Balance Below: Rich Merhige Keeping vessel machinery aligned cannot be underestimated. Alignment on yachts typically refers to shaft alignment – the positioning of two machines so the shaft centerlines of…
Balance Below: by Rich Merhige Has equipment failure cost you a charter or owner’s trip? When it comes to yacht maintenance, failure to plan results in, well, failures. The yachting…
By Rich Merhige When it comes to yacht maintenance, one recurring pattern that results in lost time and money is the lack of pre-planning. All yachting professionals are looking out…
Engineer’s Angle: by Rich Merhige Corrosion happens. On yachts, there’s a perfect storm of different metals, forces and particles that water contains, depending on the environment. If you’re dealing with…
Engineer’s Angle: by Rich Merhige When maintaining running gear and propulsion systems, O-rings and gaskets aren’t always considered a priority. In reality, O-rings and gaskets are found in many of…
Engineer’s Angle: by Rich Merhige Reliability of marine diesel propulsion and generator engines is critical, yet regular maintenance of engines and machinery is met with a great deal of resistance.…
Engineer’s Angle: by Rich Merhige Couplings are used to connect two rotating pieces of equipment together at their ends for transmitting power. There are two types of couplings: rigid or…
The mechanical systems of vessels are designed so that many of their processes necessitate the movement of something from one location to another, or a force be applied in some…
Water-jet propulsion can best be described as the propulsive force provided by the jet-reactive thrust of high velocity water ejected through a nozzle. This is similar to the propulsive drive…
When it comes to vessel maintenance, valves aren’t always appreciated for the vital role they play in a vessel’s functioning. In reality, it’s vital that they are properly maintained and…
