Arc Welding
The fundamental principle of arc welding is to connect a metal electrode to an electrical power supply, forming a closed circuit if the plate is touched with the electrode. When…

Welding Methods And Weld Defects In Shipbuilding
Welding is one of the most widely used hot-work processes used in the shipbuilding industry. The development in welding technology has enabled the industry to produce perfectly watertight and oil-tight joints. Welded…

Spiral Manoeuvre
This is a measure of the directional stability of the vessel. Imagine a situation where your vessel drifts off the course without any indication and when it is detected, the…
DECIMAL MULTIPLES AND SUB-MULTIPLES
The 11th CGPM (1960, Resolution 12) adopted a series of prefix names and prefix symbols to form the names and symbols of the decimal multiples and submultiples of SI units, ranging from…
Understanding Different Types Of Manoeuvres of a Vessel
we had an overview of the different types of manoeuvres undertaken by a ship, along with their necessary trials done post-launch. We also learnt about Turning Circle; however, is knowing the turning ability of the…
