Marine Navigation

This article examines a ship’s behaviour in shallow water compared to deep water and the resulting impact on resistance and speed.

Imagine if your vessel encounters Challenging Water Quality (CWQ) conditions that make it impossible to use the Ballast Water Treatment System (BWTS). But this raises a critical question: Do you need a Dispensation Letter before bypassing the system? Read the article to find out.

All forms of communication encompassing technical aspects in a vessel comes under the purview of a set of well-defined verbal protocols, as stipulated by IMO under the resolution of Standard Marine Communication Phrases (SMCP).

Hydrodynamics is relevant at the stages of the basic design of a vessel when its hull form is envisaged. Read along to know the aspects of hydrodynamics relevant in the realm of vessel design and naval architecture.

Mooring analysis is a key process in offshore engineering and naval architecture, used to evaluate and design systems that secure vessels or offshore structures in fixed positions.

Flags on ships play an important role in the identification of ships, communication between vessels and port authorities or shore stations, signifying if the ship adheres to certain maritime regulations etc.

Hull form optimization remains the classical approach for designers in not only reducing frictional or drag effects but also the overall resistance quotient as the wave resistance also depends greatly on the geometrical properties of the hull. 

The manpower distribution in seagoing vessels is essentially organised in something known as the ship organization chart based on position and responsibilities. Read the article to know more.
