ppt:-Piping System

Introduction 



The piping used used on a ship for circulating, loading, and discharging liquids, steam, and gases.  A ship’s ship’s piping systems systems are responsible for providing providing shipboard drainage, ballast, bal last, fire f ire protection, protection, tap water supply, sewage disposal, heat and steam supply,  ventilation  ventilation and air conditioning, conditioning, refrigeration refrigeration,, and compressed compress ed air ai r.

ENGINE COOLING WATER SYSTEM 





Fresh Water Water Circulating System is installed insta lled to cool the propulsion diesel engines, anchor winch diesel engine, and the generator diesel engines. engines. The main engine is cooled cooled by two separate systems open system And closed system. Many engine room systems also use sea water to cool oil, condense condens e steam and even produce drinking water. water.

EXHAUST PIPING SYSTEMS In the Forward Engine Room, the exhaust exhau st from both manifolds of the main mai n propulsion engine feeds a muffler muff ler.. The output of the the muffler muff ler is ducted to the aft exhaust on the forward exhaust exhaus t stack on the starboard side. The exhaust from the generator engine feeds a small muffler. The output of the muffler is ducted to the forward exhaust stack on the starboard side

Fuel System 



The Fuel System supplies diesel fuel fu el from the two storage tanks to the main propulsion engines, eng ines, anchor  winch engine, and and diesel generator generator engines. The supply line is fitted f itted with a fuel filter/water filter/water separator separator to remove water from the diesel fuel. Fuel return lines l ines are fitted with check valves, and lead from each engine to the fuel storag s toragee tanks

Lube Oil Transfer System 

The Lube Lube Oil Transfer System consists consists of a lube oil storage tank, manually manual ly operated operated transfer pump, distribution distribution lines lines and supply valves and service service hoses. Supply valves valves and service ser vice hoses are provided in the distribution lines in both engine rooms and the anchor  winch compartment. compartment. They service the main main diesel engines, engines, diesel generator set and anchor winch diesel engine. engine. The tank is fitted f itted with a fill, fill, vent, drain drain and level gage and is located in the forward engine room starboard. The tank fill pipe is located inboard of the deckhouse on the main deck.

Deck and Sanitary Drain Piping 

The Drainage System serves deck drains, galley galle y sink, lavatories, lavatories, shower, shower, and cloth clothes es washer washe r. Water Water drains toward toward the the overboard overboard discharge starboard. All drains  work  work by gravity gravity.. Gagged Gagged scuppers scuppers are fitted at the overboard discharge. discharge. There Th ere are traps in the drains for the lavatories, galley galle y sink and washer washe r. Drains for the lavatories, washer and galley sink are vented, ending endin g inboard of the deckhouse.

Fire System 

Piping is used extensively extensively throughout a ship for fire control purposes. The specific features of ship’s firefightin firefighting g equipment equipmen t are gov governed erned by the International International Convention for the Safety of Life L ife at Sea (SOLAS).



Seawater as fire extinguishing medium  At least two fire pumps and are are located located in two different different compartments  An international international shore shore con connection nection is provided provided at port and starboard starboa rd for external water supply  Pressure relief valve is fitted fi tted to mains to protect protect sudden over-pressure

 Wet  Wet fire protection protection mainly mainly for accommodation accommodation area System is filled with fresh water and pressurized by  compressed air Subsequently Subseque ntly,, water is supplied from f rom fire main Sprinkle and fire f ire main systems are separated by an alarm check valve.

Bilge System 



The Bilge System consists of the bilge pump, box strainers, valves and piping serving the main machinery machiner y spaces. The bilge pump is driven by a belt drive on the port propulsion propulsion engine. engin e.  All water is remov removed ed from from the bilge bilge and fed into into the oil/water separator system. Hose valves valves are installed in each engine room.

• Two bilge pumps are required • Suctions Suctions are arranged such that that water can be pumped out when ship is inclined 5 . °

Oily-water Separat Separator or 

 An oily water separator (OWS) is a piece of  shipboard equipment equipment that allows a vessel' vessel'ss crew to separate separate oil from bilge water before the bilge bilge water is discharged overboard.

VENTILATING AND AIR CONDITIONING SYSTEM 



The Air Conditioning System consists of a single air conditioning plant plant and suitable duct work serving serving the crew berthing, berthin g, stateroom, pilot house, galley and mess. The air conditioni conditioning ng plant consists of a condensing unit assembly, a heat exchanger, an air conditioning cooling coil (evaporator) .

Ballast System 



The Ballast System consists of piping and valves serving the t he aft ballast tank, the forward port and starboard ballast tanks, and the peak ballast tank. When the ballast tanks are being filled, the same piping system is used with sea  water f lowing lowing in the opposite opposite direction. direction. Tank level level indicators for the ballast tanks tank s are located on the aft bulkhead, in the aft engine room, beside the fire pump controller controller.. The forward port por t and starboard ballast ballas t tanks and peak ballast tank valves can be operated remotely by the hand wheels located in the crew berthing.

Hydraulic System Hydraulic Hydraulic pipes are high-pressure high-press ure pipes. These are used for: maneuvering the steering gear actuating actuatin g controllable controllable pitch propellers and thrusters lifting appliances and deck equipment moving mobile ramps for hatch covers driving cargo and ballast pumps     

Halon Sys System tem 



The fixed Halon Fire Extinguishing Extinguishing System System is located in the forward and aft engine rooms and the flammable liquid storeroom. Modes of operation are automatic, manual, and remote manual. If a fire occurs in the flammable liquids storeroom, the Halon Extinguisher Extingui sher will activate activate whether in the automatic, manual, manu al, or remote manual mode. There is no electrical tie-in with the fire alarm panel in the pilothouse pilothous e or the engine rooms

Tank Level Indicating System 



The Tank Level Indicating System provides a way of  determining the level of f luids stored stored in shipboard f luid tanks. The fluid f luid level is indicated indicated on meters meters contained in system components found throughout the ship. If the fluid level falls below or rises above these values, audible and visual signal alarm indicators can be found at system components

conclusion  

Piping system is the important importa nt aspect in a ship. ship.  A ship’s ship’s piping systems systems are responsible for providing providing shipboard drainage, ballast, bal last, fire f ire protection, protection, tap water supply, sewage disposal, heat and steam supply,  ventilation  ventilation and air conditioning, conditioning, refrigeration refrigeration,, and compressed compress ed air ai r.
