Contents. Bilge water The word is sometimes also used to describe the water that collects in this area. Water that does not drain off the side of the deck drains down through the ship into the bilge. This water may be from rough seas, rain, leaks in the hull or, or other interior spillage. The collected water must be pumped out to prevent the bilge from becoming too full and threatening to sink the ship.
How to Repurpose a Bilge Pump As a Sump Pump. Sump pumps are prone to failure of two sorts: Power outages and excessive flow. By adding a battery-powered bilge pump.
Double Acting Mk 5 Robust and lightweight polypropylene manual bilge pump range. Tough proven, reliable double acting pump - empty 2 bilges compartments at the same. Manual bilge pump wiki. There are several different types of bilge pump available on the market, each with their own operating features and benefits.
Bilge water can be found aboard almost every vessel. Depending on the ship's design and function, bilge water may contain water, oil, urine, detergents, solvents, chemicals, particles, and other materials.
Discharge of bilge liquids may be restricted and for commercial vessels is regulated under. By housing water in a compartment, the bilge keeps these liquids below decks, making it safer for the crew to operate the vessel and for people to move around in heavy weather.
Bilge maintenance Methods of removing water from bilges have included and pumps. Modern vessels usually use bilge pumps controlled by automated bilge switches. Bilge coatings are applied to protect the bilge surfaces. The water that collects is often noxious, and 'bilge water' or just 'bilge' has thus become a derogatory colloquial term used to refer to something bad, fouled, or otherwise offensive. Bilges may contain partitions to damp the rush of water from side to side and fore and aft to avoid destabilizing the ship due to the. Partitions may contain to allow water to flow at a controlled rate into lower compartments.
Cleaning the bilge and bilge water is also possible using 'passive' methods such as, which uses bacteria or to break down the hydrocarbons in the bilge water into harmless byproducts. Of the two general schools of thought on bioremediation, the one that uses beneficial microbes local to the bilge is regarded as being more 'green' because it does not introduce foreign bacteria to the waters that the vessel sits in or travels through. But archaea that are non-indigenous, all-natural and non-GMO also can be used and discharged, since the archaea will die off anyway, leaving only local indigenous microbes remaining.
Bilge alarm Large commercial vessels need bilge alarms to notify the crew how much and where the bilge is rising. These bilge alarms are electric devices that are also designed to detect leakages in the ship early before major damage is done to the vessel. Are sometimes referred to as bilge alarms. See also.

The still-intact aft bilge pump of the Swedish 17th century warship as seen from the upper gun deck. A bilge pump is a used to remove. Since fuel can be present in the bilge, electric bilge pumps are designed to not cause sparks. Electric bilge pumps are often fitted with which turn on the pump when the bilge fills to a set level. Since pumps can fail, use of a backup pump is often advised. The primary pump is normally located at the lowest point of the bilge, while the secondary pump would be located somewhat higher. This ensures that the secondary pump activates only when the primary pump is overwhelmed or fails, and keeps the secondary pump free of the debris in the bilge that tends to clog the primary pump.
Ancient bilge had a number of common uses. Depending on where the pump was located in the of the ship, it could be used to suck in sea water into a live fish tank to preserve fish until the ship was docked and the fish ready to be sold. Another use of the force pump was to combat fires. Water would again be sucked in through the bottom of the hull, and then pumped onto the blaze. Yet another suggested use for a force pump was to dispel water from a ship.
The pump would be placed near the bottom of the hull so as to suck water out of the ship. Force pumps were used on land as well. They could be used to bring water up from a well or to fill high placed tanks so that water could be pressure pumped from these tanks. These tanks were for household use and/or small-scale irrigation. The force pump was portable and could therefore, as on ships, be used to fight fire.

Force pumps could be made of either wood or bronze. Based on ancient texts, it seems that bronze was the preferred material since it lasted longer and was more easily transported.
Wood was easier to build, put together, and repair but was not as durable as bronze. Because these were high-value objects, few are found in shipwrecks; they were often recovered after the ship sank. Force pumps were fairly simple in their construction consisting of a cylinder, a piston, and a few valves.
Water would fill the cylinder after which the piston would descend into the cylinder, causing the water to move to a higher placed pipe. The valve would close, locking the water into the higher pipe, and then propelling it in a jet stream. Archimedes' screw. The can raise water efficiently. The Greek writer described how King Hieron II commissioned Archimedes to design a huge ship, which could be used for luxury travel, carrying supplies, and as a naval warship.
Syracusia is said to have been the largest ship built in classical antiquity. According to Athenaeus, she was capable of carrying 600 people and included garden decorations, a and a temple dedicated to the goddess among her facilities.
Since a ship of this size would leak a considerable amount of water through the hull, the was purportedly developed in order to remove the bilge water. Archimedes' machine was a device with a revolving screw-shaped blade inside a cylinder.
It was turned by hand, and could also be used to transfer water from a low-lying body of water into irrigation canals. The Archimedes' screw is still in use today for pumping liquids and granulated solids such as coal and grain. The Archimedes' screw described in Roman times by may have been an improvement on a screw pump that was used to irrigate the, but this is disputed due to a lack of actual evidence. References.
