MISSION COP- FREQUENTLY ASKED QUESTIONS (PART-3)


WHAT IS EARTHING?




The connection between electrical appliances and devices with the earth plate or electrode through a thick wire of low resistance to provide safety is known as Earthing or Grounding. Earthing System or Grounding System in Electrical network is for safety purpose. 
The Main objective of earthing system is to provide an alternative path for dangerous current to flow so that the problem of electric shock and damaging of equipment’s can be cured.Metallic part of an equipment are grounded and if the equipment’s insulation fails than there will be no dangerous voltages present in equipment box.
The circuit gets sorted and fuse will blow immediately, in case the live wire touches the earthed case Particularly, it can affect the magnitude and distribution of current in short circuits through the system and the effects of the system are on equipment and people who will near to the circuit.
Why you should have an Earthing System?This question is generally arises, when you have all the right equipment’s, wires, socket and well maintained electrical devices, Yet, why is there need of an Earthing system.The Answer is very simple..Earthing system makesyour building electrically shock free and gives you a safe place.Below are some of the points which can easily make you think about earthing system.




1. Safety for Human Life, Electrical Devices and Building

• It saves the human life from danger of electrical shock which can cause death, by blowing a fuse
• Protects your electric equipment’s or devices
• It provides a safe path for lighting and short circuit currents.

2. Voltage Stabilization You know that electricity has many sources. As Every transformer considered to be a separate source.
And if there is not a point which will act as common point, then it becomes more difficult to make a calculation between these sources.In the Electrical distribution systems, Earth is the omnipresent conductive surface, which makes it a universal standard for all electric system.

3. Over Voltage Protection Earthing System provides an alternative path in the electrical system to minimize the dangerous effect in the electrical system which happens at the time of lighting and unintentional contact with high voltage lines.

SMPEP (Shipboard Marine Pollution Emergency Plan)

Image
SMPEP (Shipboard Marine Pollution Emergency Plan) Background MARPOL Annex II Regulation 17 requires every chemical tanker of 150 GT and above to carry a SMPEP. Scope of this plan is to provide guidance on the actions to be taken if a spill of oil or noxious liquid substance has occurred or is likely to occur. The plan is in line with IMO MEPC. 54(32), MEPC.86(44) and the SMPEP guidelines in Resolution MEPC.85(44). Plan Approval by the Administration or a Recognised Organisation (RO) on behalf of the Administration is mandatory.   Contents     Reporting Requirements     Steps To Control Discharge     National And Local Co-Ordination     Additional Information     List Of Coastal State Contacts     List Of Ship Interest Contacts     Summary of Flow Chart And Checklists     IΜΟ Resolution A.851(20)     Vessel Specific Information Info/Plans Required     Ship Specific Information

How and Why to Take Manual Sounding On Ship?

How to take Manual Sounding? Sounding is a term used for taking a measurement of the amount of fluids in the tanks of a ship. Different type of sounding methods are used on board ships. In this article, we will take a look at the importance of taking manual sounding and the method of taking the same. Why Manual Sounding? On board ship, it is very important to keep the updated record of the quantity of liquids (in all forms) present in various tanks. A ship is fitted with different types of automatic and hydraulic/ pneumatic/ mechanical sounding measuring systems wherein the level of the liquid can be checked remotely or locally without manually measuring and calculating the liquid amount inside the tank. One cannot entirely depend on the automation and mechanical devices, especially when it comes to those substances, for which, negligence can cause oil pollution and machinery damages. Manual sounding is always preferred by all seafarers (deck and en

What is Ship Oil Pollution Emergency Plan (SOPEP)?

Image
What is Ship Oil Pollution Emergency Plan (SOPEP)?   Understanding SOPEP   Sopep stands for Ship oil pollution emergency plan and as per the MARPOL 73/78 requirement under Annex I, all ships with 400 GT and above must carry an oil prevention plan as per the norms and guidelines laid down by International Maritime Organization under MEPC (Marine Environmental Protection Committee) act. The Gross tonnage requirement for oil tanker, according to SOPEP, reduces to 150 GT as oil itself is a kind of cargo which doubles the risk of oil pollution. Master of the ship is the overall in charge of the SOPEP of the ship, along with the chief officer as subordinate in charge for implementation of SOPEP on board. SOPEP also describes the plan for the master, officer and the crew of the ship to tackle various oil spill scenario that can occur on a ship. For oil tankers, action plan widens regarding the cargo handling and cargo tanks containing huge quantities of oil. Content
