• Air filter

   
  A particulate air filter is made of porous or fibrous materials and is used to filter the air of solid particles like dust, pollen, mold, and bacteria.

• Auxiliary Engine

• Auxiliary machinery, auxiliaries

   
  A term used to refer to all equipment that isn’t used for propulsion, such as machinery and tools, in a ship.

  Auxiliaries, equipment, and machinery used on the deck include cranes, winches, windlasses, steering systems, and other machinery used to operate the ship and handle cargo.

  Auxiliaries in the engine room include all equipment such as coolers, heaters, pumps, separators, and others that help the propulsion plant function.

• Ventilation filter

• Beta Ratio

   
  The beta ratio is an indicator of how well a filter works:
  For example, if one of two particles (>xmm) in the liquid passes through the filter, the beta ratio at xmm is equal to 2, if one of 200 particles (>xmm) passes through the filter, the beta ratio is equal to 200.

• BWTS – balast water treatment system

   
  A system known as a ballast water treatment system (BWTS) is used to remove and eliminate biologically active biological organisms (zooplankton, algae, and bacteria) from ballast water.

• Bearing

   
  An element that appears frequently in mechanical systems where two parts move in relation to one another. A bearing allows for the least amount of frictional losses during the transfer of forces.

• Bilge

   
  1. the place where side and bottom meet.

  2. where bilge water may collect in holds and machinery spaces at lower levels.

• Bilge alarm, 15 ppm bilge alarm

   
  The oil content of the effluent from the oily water separator should not exceed 15 parts of oil per million parts of water, according to Regulation 16(5) of Annex I of MARPOL 73/78. When this level cannot be maintained, the “15 ppm bilge alarm” alarm system will go off and automatically stop any discharge into the ocean.

• Bilge Pump

   
  Drainage pumps for the ship’s various compartments.

  The bilge pumps on passenger ships must be housed in their own, watertight compartments.

• Bilge System

   
  A piping system designed to dispose of water that may accumulate in the vessel’s interior spaces (holds, machinery spaces, cofferdams) as a result of condensation, leakage, washing, fire fighting, etc. As a result of the piping systems suffering only minor damage, it must be able to control flooding in the engine room. The bilge system, however, is not designed to handle flooding brought on by a significant hull damage that was not promptly repaired.

• Bilge Water

   
  The water that accumulates in a ship’s bilges, which typically smells foul and is noxious. Additionally, bilge water includes liquids from sludge tanks, internal drainage systems, machinery spaces, and various other sources. This mixture is collected in the holding tank for bilge water, which is typically kept warm. Regardless of where it comes from, bilge water needs to be treated to bring the oil content down to levels compliant with international laws before being released into the environment.

  Be aware that the bilge water may emulsify when cleaning products, emulsifiers, solvents, or surfactants are used. To reduce the amount of these substances in a ship’s bilges, appropriate measures should be taken.

• Bow Thruster

   
  To increase maneuverability, a lateral thruster was installed in an athwartships tunnel close to the bow. When the bow thruster is activated while the ship is moving forward, the vacuum created in the wake of the water jet from the thrusters partially cancels out the thrust. When the ship is moving at four to six knots, the effect is at its worst. An anti-suction tunnel can be added in these situations to relieve the vacuum on the hull.

• Brush (electric)

   
  A brush, also known as a carbon brush, is an electrical contact that transfers current from stationary wires to moving components, most frequently in the form of a rotating shaft.

• Bulk Cargo

   
  Unpacked cargo with the ability to flow, pump, or pour that is brought aboard. Petroleum and its derivatives, coal, grain, fertilizers, minerals, ores, bauxite, and cement are the most typical bulk cargoes. Dry bulk cargoes are transported by specialized ships, some of which are named after the materials they carry. Carrier types in this category include grain, coal, and ore carriers.

  Solid bulk cargo is any material, other than liquid or gas, that is loaded directly into the cargo spaces without the use of any intermediate form of containment and is made up of a mixture of particles, granules, or other larger pieces of material, generally uniform in composition.

• Bushing

   
  A bushing is a hollow electrical insulator used in electric power that enables an electrical conductor to safely pass through a conducting barrier, such as the case of a transformer or circuit breaker, without coming into contact with electricity.

• By-pass

   
  Anything designed to direct and divert a fluid from its primary flow path.

• Cardan Shaft

   
  A mechanical setup that allows for the flexible alignment of a driven and driving shaft, i. e. an adaptable coupling.

• Coalescer

   
  An apparatus made of a substance whose surface encourages coalescence.

• Coalescence

   
  The process of combining tiny oil droplets into larger ones that will eventually separate due to gravity. To improve separation down to a few parts per million, a coalescent filter is used downstream of an oily water separator.

• Cock

   
  An arrangement of valves where the liquid passes through a hole in the middle plug.

• Coil

   
  A device used to exchange heat so that energy can be moved between sources. Coils for converting refrigerant to air and refrigerant to water are both used in ground source heat pumps.

• Connectring Rod

   
  The component of a piston engine that joins the piston to the crankshaft is called a connecting rod.

• Desiccant

   
  A material with the ability to absorb moisture, e. g. hydrated calcium chloride. It’s frequently employed as a drying agent.

• Diaphragm

   
  1. a biconvex plate with two halves. Its upper half is covered in nozzles and fits between a steam turbine’s rotor wheels.

  2. a thin metal plate, either flat or corrugated, that is used in pressure measuring equipment.

  3. a flexible synthetic rubber component that is used to create a pressure-tight chamber for a pneumatic valve actuator.

• Diesel Engine

   
  The internal combustion engine known as the diesel engine, which bears Rudolf Diesel’s name, is referred to as a compression-ignition engine because the air in the cylinder is heated to a higher temperature as a result of mechanical compression.

• Differential pressure

   
  The pressure difference between two points is known as differential pressure.

• Diffuser

   
  A chamber that surrounds the impeller of a centrifugal pump or compressor and is where some of the fluid’s kinetic energy is changed into pressure energy due to an expanding cross-sectional area of the flow path.

• Discharge Valve

• Emulsion

   
  An emulsion is a mixture of two or more liquids that are typically incompatible (unblendable or immiscible) due to liquid-liquid phase separation.

• Exhaust Valve

   
  The valve through which exhaust gases leave the engine. Two components make up the exhaust valve: a spindle and a valve housing.

• Filter

   
  A tool for mechanically removing solid contaminants from liquid or gas. Before oil enters the finely machined engine parts, small dirt particles are removed from it using fine mesh filters.

• By-pass filter

   
  When a certain differential pressure is reached, a filter opens up a different, unfiltered flow path around the filter element.

• Duplex filters

   
  With the exception of the number of elements and the ability to switch the flow through either element, duplex filters are similar to simplex filters. A duplex filter can be made up of several single element filters placed in parallel or it can be made up of two or more filters placed together inside of a single housing. By closing valves, the entire flow can be changed to pass through any one component.

• Full-flow filter

   
  Any flow entering the filter’s inlet port will not pass through the filtering element, according to the definition of full-flow when used in reference to a filter. However, a bypass valve is typically present in full-flow filters that is programmed to activate at a specific pressure drop and direct the flow past the filter element. Flow won’t be excessively restricted by a dirty element as a result.

• Filter with back flushing

   
  A filter that can be cleaned automatically. For the purpose of cleaning the filter’s surface of impurities, back flashing is the process of switching the fuel flow.

• Filtration

   
  Filtration is the process of removing solid particles from a fluid by allowing the fluid to pass through a filter medium where the particles are retained.

• Feinheit, µ Micron rate

   
  The filter fineness or µ refers to the particle size, which a filter can filter out measured by its effectiveness/ filter fineness.
