Frequently Asked Questions on Marine Engineering Notes
Question 1.
Explain the ISM code and its significance.
Answer:
ISM code is used to ensure the safety of human life and prevent injuries and loss of life. It also extensively covers how to avoid damage to the ship or any other marine vehicle and the surrounding environment. The international safety management code is a set of guidelines to be followed earnestly by all to ensure safe management and operations of ships at sea.
- Construction parts and machinery check
- Safety equipment and other mandatory equipment
- Stability of ship and proper loading and unloading of cargo and materials.
- The operating guidelines and parameters
- Maintenance guidelines and emergency procedures
- Health and safety
- Proper functioning of the ship
- Adhering to the guidelines set by IMO
Question 2.
What do you understand by the terms flash point and fire point?
Answer:
The terms flash point and fire point signify flammability conditions required to be met for the flame to ignite. These terms are defined to differentiate between the conditions and stages and difference in temperatures.
- Flashpoint – Flashpoint signifies the lowest temperature at which the liquid/vapour ignites by a flame or spark or any other nearby source of ignition.
- Fire point – Fire point is the lowest temperature at which if the liquid/vapour is heated will start to burn continuously when ignited by a spark, flame or any nearby source of ignition.
The flashpoint temperature is below the fire point temperature. Another term auto-ignition temperature signifies the temperature at which when the liquid/vapour or a mixture of air doesn’t need any source of ignition and ignites without any spark, flame or nearby source of ignition.
Question 3.
What is fatigue crack, and how can it be identified?
Answer:
Fatigue crack is primarily due to any fluctuations in the stress applied to the component and is propagated further.
Stress raisers are rough surfaces where the stress is applied and can easily lead to a fatigue crack. It is advisable to smoothen the body like this.
Usually, oil holes are sites of fatigue cracks. The number of oil holes should be minimised and should have a wider radius and should be smoothed out as much as possible.
In areas where tensile stress plays a role are a common area for the weakening of fatigue strength and can lead to fatigue cracks. Often cold rolling is used in these areas to increase the fatigue strength in these areas.
Materials which are hardened for specific purposes can lead to fatigue cracks due to higher stress on smaller components.
Question 4.
Explain the term “surge” in the turbine?
Answer:
A surge is a complete stall that results in the disruption of the airflow inside the compressors of the turbine. It is a disruptive mode of operation which can be seen as a pulsating pressure on the blades. It is a violation of the dynamic gas stability inside the compressor system of the turbine.
It can cause a temporary drop in power or a complete loss of compression in case of a surge. The compressor stalls are of two types, either rotational or axisymmetrical. Surges in systems can be controlled or avoided by better designs of compressor and turbine systems.
