In the pulsating heart of a marine vessel, lies a crucial workhorse: the marine boiler feed water multistage pump. This unsung hero relentlessly pushes treated water against immense pressure, feeding the insatiable boilers that power the ship’s propulsion and essential systems.

Marine hydrophore systems are essential components of a vessel’s infrastructure, responsible for maintaining the necessary water pressure for various onboard applications. These systems play a critical role in ensuring the availability of freshwater for domestic and operational use. It consists of a hydrophore tank, one or more pumps, pressure switches, valves, gauges, and other accessories….
Centrifugal pumps are critical components on board vessels, responsible for various fluid-handling tasks such as cooling, ballasting, and transferring liquids. They are simple and reliable machines that operate on the principle of converting mechanical energy to kinetic energy and then to pressure energy. However, like any other machinery, they are subject to wear and tear…
Marine fresh water generators play a critical role in ensuring a continuous supply of clean, fresh water onboard ships and vessels. For proper operation of fresh water generators please follow THIS LINK. Regular maintenance and timely troubleshooting are essential to keep these systems in optimal working condition. In this article, we will explore the maintenance…
Centrifugal pumps play a critical role in various industrial applications, including marine vessels. They are responsible for transferring fluids by converting mechanical energy into hydraulic energy. To ensure optimal pump performance and prevent unexpected failures, periodic overhauling is essential. This article will delve into the significance of shaft alignment during pump overhauling, explore different problems…
Recently I have worked on a vessel where all mooring equipment was hydraulically powered and due age of the vessel we have encountered a lot of trouble with the system (pipe failure, pipe damage, hydraulic hoses and connection failure, pumps’ failures etc.). Apart from this, the vessel was equipped with hydraulically driven cargo cranes which…
Within the pump, the mechanical seal is the component that acts as a barrier between the rotary components and the stationary elements. The seal needs to be able to prevent leakage at three different places. In the space between the faces of the seal (both rotational and fixed). Between the rotating element and the shaft…
Failures of the pump’s bearings are the cause of pump outages and repairs nearly as frequently as failures of the pump’s mechanical seals. Centrifugal pumps often make use of both rolling element (anti-friction) bearings and sliding element (plain) bearings in their construction. Each of these two groups of bearings can be discovered in small as…
The anti heeling system is part of the ballast system which has been explained in one of my previous posts and can be found if follow thins link. The anti-heeling tanks are located on the port and starboard sides of the ship and are filled and emptied by means of the ballast system. A reversible…
All along the ship’s length, the ballast system utilizes water tanks positioned in the double bottom, along the sidewalls, and beneath the ship’s main deck.In order to keep the ship’s draught and trim proper, to provide maximum stability, and to keep the ship’s stress and bending moments within acceptable limits, water is added to or…
