Moreover, there are pilot valve assemblies located outside the bowl. They are used for controlling the movements of the main …
Due to centrifugal force, the oil displaces the water and the sludge to the bowl periphery and rises upwards through the disc stack. The clean oil is then discharged through the clean oil outlet. Sludge and water particles accumulate at the bowl periphery and separated water is continuously discharged through the water outlet.
A screw pump is a subset of positive displacement pump that use one or more than one screw; to perform pump action along its spindle axis. The complete ... The main job of screw pumps on ship is to; transfer fuel oil …
Oil water Separator uses Stokes' Law to define the speed of the float of an object / particle based on its specific gravity and size. In this tool, oil will accumulate above the water surface. Parts and functions of oil water separator : Blige Pump, functions as a sewer. Bilge Separator (Stage I), functions as a water separator tube with oil.
The following requirements shall be subject to the sludge tank of Ships constructed (the keel of the ship is laid or a similar stage of construction) on or after December 1990. ... Although the pipeline for sludge pump shall be connected directly to a sludge pump, in case of oil residue (sludge) service tank (ie, waste oil tank) that directly ...
Attached Gear pump: A general construction of centrifuge consists of a horizontal shaft driven attached supply or discharge gear pump. In some system an external supply pump may be installed in place of the attached pump. Sludge discharge mechanism. Fig. shows diagrammatically the method of sealing and sludge ejection for a self-cleaning purifier.
The international shore connection is a universal hose connection that is to be provided on all ships as per the IMO SOLAS requirement.. The purpose of the International Shore Coupling is to keep a standby hose attachment to get a connection from shore or from other ships for shipboard firefighting, in case there is a total failure of pumps onboard. ...
The settling tank in a ship is a deep tank in the engine room which is used for gravity-based pre-cleaning of fuel oils. ... The function of settling tank is to separate the sludge and water contained in the fuel oil,to act as a buffer tank and to provide a suitable constant fuel temperature of 50-70℃ .This can be improved by installing two ...
This oil cannot be re-used so it is called dirty oil. The scavenge drain oil is mainly burned in the incinerator which is present in the ship to burn the wast sludge and oils which cannot be used. Pump room. Normally pump rooms are found on liquid carriers. They are dedicated to cargo pumps and have independent ventilation systems.
The Ship Aero Sewage Treatment Plant (STP) is a pivotal component in managing waste on board, ensuring that ships can treat sewage effectively while adhering to stringent international standards. This system …
The refrigeration plants on merchant vessels play a vital part in carrying refrigerated cargo and provisions for the crew on board. In reefer ships, the temperature of the perishable or temperature sensitive cargo such as food, chemical, or liquefied gas, is controlled by the refrigeration plant of the ship.
Compared with bilge water, fuel oil sludge is generally less varied and the quantities are more predictable, provided the quality of the fuel oil remains constant. Sludge waste is much heavier than bilge water. As a general rule of thumb, approximately 1-2% of the heavy fuel oil burned in a vessel's main engine and generators ends up as ...
The North Sea and Baltic Sea are among the emission control areas, for example. Since early 2020 a maximum sulphur content of 0.5 percent in ship fuel applies worldwide to lower the air pollution caused by ships effectively and sustainably. The easiest and fastest solution to reduce sulphur emissions is the use of fuels that contain less sulphur.
Sludge tanks are storage tank for oily water with a high percentage of oil and little water. The sludge pumps transfer the oily sludge to the incinerator waste oil tanks after which they are incinerated in the incinerator.

Cleaning HFO Tank. 3. Pumpability: Many times, if the heating system of the bunker tanks fails or face a problem, it becomes difficult for the ship's staff to pump the heavy fuel oil from bunker to settling tank due to the high viscosity of the oil. If the heavy fuel oil is of inferior quality, it will choke the filter frequently, increasing the workload of the ship staff onboard ship.
It also helps in transferring the sludge from sedimentation tank, supply air to the activated carbon tank and to back flush the sludge. Discharge Pump. The discharge pump is provided in a duplex and mounted on the last compartment of the STP. They are centrifugal pumps of the non-clog type coupled to their respective motors.
