Offshore Oil Production Platforms: How they Work There are numerous types of offshore oil and gas production platforms which can either sit or be fixed on the seabed or float, but the processing of the hydrocarbons is the same. The fluids and gasses are separated into different process chains before being exported ashore via subsea pipeline.
Test and Overhaul of Fuel Injection Valves This article discusses the testing and the overhaul of fuel injectors of marine engines,the testing of the needle and guide condition of the fuel valve, and the procedure to overhaul and inspect the injectors taken out of the marine diesel engines.
Role Of Compressed Air In Starting a Marine Disel Engine Do you know how diesel engines are started in ships? Equivalent in size to a four-story building, the main propulsion engine is started with the help of compressed air at a pressure of 30 bar. Learn more about where a ship gets its compressed air supply from.
Fresh Water from Sea Water on Ships When preparing for a voyage ships take on fresh water which is supplemented throughout the voyage by water making plants. Fresh water is used in motorships as an engine component cooling medium, but steamships only use distilled water produced by the water-making plant for boiler feed make-up.
Simple Fluid Mechanics Experiments and Calculations This article gives you the concept of a simple fluid mechanics experiment using Pascal's law as a principle. Also read a discussion of the calculation related to the experiment and an example application in the hydraulic steering system that is employed on board a ship for steering.
Control Tests on Ships Explained The main engine and the steering engine are located aft and far from the bridge and controlled by a maze of wires, pipes, machines, and electronic devices. Prior to entering a port and departing the port, these control systems have to be tested to ensure they are working properly and are effective.
Starting & Reversing Problems in Marine Engines There are a number of reasons for starting and reversing problems in marine engines. This malfunction is one of the most frightening and dangerous situations to encounter when maneuvering a ships main diesel engine, but it can be avoided through regular maintenance of the air start components.
Functions of Ships Main Engine Thrust Block, Prop Shaft, and Stern Tube In a marine engine the function of the thrust block, propeller shaft, and stern tube are closely related, being responsible for the efficient transmission of the engine’s power to the propeller and ensuring the control of torque and propeller shaft alignment from the thrust block to the stern tube.
Use of Lubricants and Lubricant Parameters on Ships The use of lubricants and lubricant parameters on ships is an important role managed by the main engine lube oil system.
This consists of a pump that pressurizes the oil, circulating it through a set of filters and a cooler before distribution to all the moving components of the diesel engine
