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...

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. ...
