Introduction The Automatic Identification System (AIS) is a shipborne tracking technology that enhances maritime safety by transmitting and receiving vessel information through VHF frequencies. AIS allows ships and coastal authorities to identify, monitor, and track vessels in real time, significantly improving situational awareness. Although AIS improves navigation safety, it is only an aid—it cannot replace […]
Understanding the Prow of a Ship
Introduction: Understanding Ship Geometry In naval architecture, the hull is divided into three regions: The parallel middle body is where the hull edges appear linear and continuous, while the bow and stern represent the more curved forward and aft regions. Within this forward region lies a critical feature: the prow. What Is the Prow of […]
Margin Lines in Naval Architecture
Introduction: Damage Stability and Safety Margins In naval architecture, damage stability is one of the most important considerations in vessel design. It deals with the ways a ship might sink or lose stability if physical damage causes water ingress into watertight spaces. Two primary methods exist for assessing damage stability: Since 2009, all dry cargo […]
How Much Cargo Can a Ship Carry?
Introduction: Measuring the Weight of Ships When we talk about the “weight” of a ship, we usually mean displacement—the mass of the ship plus everything it carries, equal to the weight of the water displaced to stay afloat (Archimedes’ principle). Displacement is often divided into two parts: Thus, a ship in its lightship condition carries […]
Working of Marine Boilers Explained
Introduction: Boilers in the Maritime Industry Boilers have been integral to ships since the age of steam vessels. Even today, they remain indispensable, generating steam by boiling water at high pressures and temperatures. This steam supports a wide range of onboard functions, from heating heavy fuels on tankers to powering pumps, turbines, and air conditioning […]
10 Situations When a Ship’s Generator Must Be Stopped
Introduction: The Heart of a Ship’s PowerThe generator onboard is the powerhouse of a vessel, ensuring that critical systems remain operational. Regular maintenance and timely overhauls are essential, but sometimes problems arise suddenly. A skilled marine engineer must recognize the early warning signs and take immediate action before minor issues escalate into major disasters. Every […]
