Engine room watch-keeping engineers depend on various gauges, thermometers and pyrometers to ensure the engines are running and operating at optimum efficiency. They also depend on the sense of touch to determine temperatures; handheld infrared thermometer use in the engineroom can compliment this
Purifiers or centrifugal separators are high-speed rotating machinery used on board for purifying oil. Purifiers have very special features and operating characteristics. The drive system is specially designed with gear and friction clutch arrangements.
A ship can be considered as a mobile power plant. Most of the machinery is driven electrically, which thus makes for a huge electrical power demand. This makes a shipboard electrical power distribution system very important. This article is about the layout of the main switch board and the bus bar.
The Main propulsion engine had a special type of lube oil sump arrangement. The Engineers had no knowledge about this special arrangement, which lead to the flooding of engine room with lube oil. Approximately 8 tons of lube oil was lost. Read here to learn more about the incident.
When the ship’s main diesel marine engine breaks down at sea, it is imperative that the Engineering Officers affect repairs as quickly as possible in order to restore power and steerage. This means that sufficient spares and tools must be carried to repair the marine power diesel engine.
We all know that a fire requires heat, fuel, and oxygen. Have you ever wondered how a bacteria could be the source of ignition? Read here to know about the sequence of events and investigation of an engine room fire caused by thermophilic bacteria.
This article discusses exhaust valves used in the marine diesel, properties of materials, new design features, causes for exhaust valve burning, indication of exhaust valve leakage, stress on the exhaust valve, stress failures, and exhaust valve problems.
It was 1968 and I was sailing as 4th Engineer on an Ulster Steamship general cargo ship trading between the UK and the Great Lakes. The main engine was a two-stroke Werkspoor marine engine that ran quite well on diesel fuel but required a heavy maintenance schedule, which we carried out in port.
I was sailing third engineer on an Ulster Steamship cargo ship in 1969. We were on the UK to Montreal, Quebec and Great Lakes run, which was great in the summer months, but the winter weather could turn nasty giving a rough old passage across the North Atlantic, especially with a twisted prop blade!
Before starting any rotating machinery it is a practice to check the lubricating oil level. But here is an incident which happened due to lack of lubricating oil in the gear case of purifier even after checking the level. Read here to know how a wrongly fitted sight glass caused a gear failure.
