Steering Gear System In Ship

The efficiency of the performance of steering gear depends on some main aspects. These basic requirements to be invariably met by all steering gears are guided by rules set by classification societies. They can be briefly outlined as:

• As per standard requirements, the steering gear should be capable of steering the ship from 35 degrees port to 35 degrees starboard and vice-versa with the vessel plying forwards at a steady head-on speed for maximum continuous rated shaft rpm. and summer load waterline within a time frame of a maximum of 28 seconds
• With one of the power units inoperative, the rudder shall be capable of turning 15 degrees port to 15 degrees starboard (and vice-versa) within a time frame of 1 minute with the vessel moving at half its rated maximum speed of 7 knots (whichever is greater) at summer load line
• The major power units and the control systems are to be duplicated so that if one of them fails, the other can easily substitute for them as standby
Emergency Power Supply: The steering gear system is to be provided with an additional power unit (hydraulic pump etc.) connected to the emergency power supply from the Emergency Generator, which shall be capable of turning the rudder from 15 degrees from one side to another side within 60 seconds with the vessel moving at a maximum service speed or 7 knots, whichever is greater

- Types of Steering Gears On Ships -

As ships continued to grow in size and became faster, modern systems easing human effort were incorporated. Basically, there are two types of commonly used steering gear systems present:

• Hydraulic
• Electro-hydraulic type

Though the system has undergone some major evolution, the basic physics of operation remains the same.

The main control of the steering operations is given from the helm of any ship, similar to an automobile where the entire control of the vehicle’s “steer-ability” rests on the steering wheel of the driver. The ‘control force’ for turning is triggered off from the wheel at the helm, which reaches the steering gear system.

The steering gear system generates a torsional force at a certain scale which is then, in turn, is transmitte

❌Just installing a boiler on a ship doesn’t guarantee the efficient working of a boiler. ♨️

✅When a boiler installation is done on board a ship, it can only be considered as complete, when different types of boiler mountings, including boiler controls, are fitted to ensure the safe and efficient operation of a gas boiler.🔥

• What is lubrication system in ship?

The lubrication system of an engine provides a supply of lubricating oil to the various moving parts in the engine. Its main function is to enable the formation of a film of oil between the moving parts, which reduces friction and wear.

• Types of lubrication systems

Oil Lubrication System.
Splash Lubrication System.
Recirculating Oil System.
Air-Oil Lubrication System.
Grease Lubrication System.
Dual Line Lubrication Systems.
MQL (Minimum Quantity Lubrication) System & Near Dry Machining.
Wet Sump Lubrication System.

• What are the 5 functions of the lubrication system?

Its basic functions within an engine include reducing friction, cooling, sealing, cleaning, and serving as protection for moving parts.

• What is the most common lubrication system?

Dry Sump Lubrication System: This is also a most common form of the lubrication system. Under this form, a holding tank positioned in the airframe or mounted on the engine stores the lubricating oil.

• What is the importance of cooling system?

The cooling system serves three important functions. First, it removes excess heat from the engine; second, it maintains the engine operating temperature where it works most efficiently; and finally, it brings the engine up to the right operating temperature as quickly as possible.

• What is HT and LT cooling system?

LT or low temperature fresh water is used to cool the engine, and HT or High Temperature Sea water is used to cool water in the Low temperature circuit via a heat exchanger.

Checking Tappet Clearance.👌⚙️⛓️⚓️

What is the purpose of tappet clearance❓️ 🤔
✅️ The main purpose of tappet clearance is to allow a small expansion gap of the valve stem and pushrods to accommodate the effects of a heated engine.

Why is valve clearance so important❓️

✅️ Too much or too little valve clearance can result in poor performance or a rough idle because the engine can't “breathe” normally and operate at peak efficiency. Too much clearance means the valves will likely clatter and, over the long term, cause damage to the valves, camshaft lobes or rocker arms.

What will happen if tappet clearance is less❓️

✅️ So less air for combustion. Power will be reduced. Fuel consumption will increase, engine may become unbalanced, exhaust temp. will be very high. In worst condition, valve may remain open, resulting in loss of compression pressure, burning of exhaust valve, T/C fouling will increase.

What happens if tappet are not adjusted❓️

✅️ The valve will open sooner and close later. You may observe air leaks in the combustion chamber, leading to less available air for proper combustion. The power and performance of the engine will decrease.

When should I take tappet clearance❓️

✅️ TAPPET CLEARANCE IS ONE OF THE MOST IMPORTANT CLEARANCE IN A 4 STROKE ENGINE. IT SHOULD BE TAKEN EVERY MONTH AS CLEARANCE MAY CHANGE DUE TO CONTINUOUS RUNNING OF AUXILIARY ENGINE. TO TAKE A CORRECT TAPPET, THE POSITION OF INLET AND OUTLET VALVES IS VERY IMPORTANT.

• What is Fresh Water Generator?

Fresh water generator is a device which is used to convert seawater to freshwater on ship.

• How does a fresh water generator work?

The submerged tube type fresh water generator explained below uses the heat from main engine jacket cooling water to produce drinkable water by evaporating seawater due to the high vacuum, which enables the feed water to evaporate at a comparative low temperature.

• What is the importance of fresh water generator?

Fresh water generators (FWG) convert seawater (saltwater) to fresh water. FWGs are a common site on many marine vessels as it allows them to generate the fresh water they need whilst at sea. The process of generating fresh water is achieved via distillation.

• What is generated by fresh water?

Fresh water produced from fresh water generator is used for drinking, cooking, washing and even running other important machinery which use fresh water as a cooling medium. Fresh water is generally produced on board using the evaporation method.

• What are the two simple working principle of fresh water generator?

A fresh water generator works on two simple principle of distillation and effect of pressure on boiling point.
