This video provides a step-by-step guide on calculating a ship's Underkeel Clearance (UKC) in accordance with the company's procedures. It's important to note that procedures may vary among different companies, and this tutorial is intended solely as a reference. The process involves assessing depth accuracy through the use of a Category of Zone of Confidence (CATZOC).

The Ship's UKC stands for "Ship's Under Keel Clearance." It refers to the vertical distance between the lowest part of a ship's hull, usually the keel, and the seabed beneath it. UKC is a critical parameter in maritime navigation as it determines the minimum depth of water required for a ship to safely navigate without grounding.

The Electronic Navigational Chart (ENC) within the Traffic Separation Scheme (TSS) is deliberately scaled down, making the depth-sounding appear shallower in the Northbound lane. However, adjusting it to a larger scale reveals ample navigable water within the traffic lane.

Correction to the last part of the video. The DWA is 0.109m, not 0.136m. Subtract 0.109m to the initial draft to find the final draft.

This video shows how to calculate the fresh water and dock water allowance and determine the final draft due to the change in the water density.

Fresh Water Allowance (FWA) is the number of millimeters in which the ship's mean draft changes when she passes from salt water to fresh water or from fresh water to salt water when she is loaded to its summer displacement.

Dock Water Allowance (DWA) is defined as the number of millimeters in which the ship's mean draft changes when she sails from salt water to dock water or when sailing from dock water to salt water when she is loaded to its summer displacement.

A ship's ETA (Estimated Time of Arrival) is the anticipated time at which the vessel is expected to arrive at its destination. It is a crucial piece of information used in maritime operations for planning, coordination, and communication among ship operators, port authorities, shipping agents, and other stakeholders.

In this video, it shows you how to calculate ETA manually with the different time zones and when crossing IDL. It also shows how to calculate the steaming time.

In this video, we break down the difference between Gross Tonnage (GT) and Net Tonnage (NT) in simple terms.

Gross Tonnage, represents the total volume of all enclosed spaces in a ship. It gives us a picture of the ship’s overall size and capacity. It’s not about weight but the size of the ship based on the spaces enclosed within its hull and superstructure.

Net Tonnage refers to the volume of cargo carrying spaces. It is indicative of the vessel’s earning potential. Net Tonnage is about the revenue-earning spaces on the ship.

This video shows the difference between the Closest Point of Approach (CPA) and the Bow Crossing Range (BCR). These terms are essential for collision avoidance and safe navigation.

CPA represents the closest point at which two vessels will approach each other if both maintain their present courses and speeds. It is a point along the target’s relative motion line at which the shortest distance will occur between own ship and the target if both continue on their present courses and speeds.

BCR is the distance at which a target vessel will cross ahead of own ship’s bow or astern if both maintain their present courses and speeds.

In this comprehensive tutorial, we dive deep into the world of tank-sounding tables and their crucial role in marine engineering, ship stability, and cargo management. Whether you're a maritime enthusiast, a ship's officer, or a student looking to expand your knowledge, this video is packed with valuable information and practical insights.

Mass is commonly defined as the measure of the amount of matter in an object. It is typically measured in units such as kilograms (kg) in the International System of Units (SI) or grams (g) in the metric system. In some contexts, other units such as pounds (lb) or ounces (oz) may be used.

This video shows how to use a hydrostatic table to determine a ship's displacement. It includes interpolation to determine ship displacement. It also defines lightweight and deadweight.

A ship's hydrostatic table, also known as a hydrostatic data table or hydrostatic curves, is a tabulated set of data that provides information about the buoyancy characteristics of a ship at various drafts or immersion levels. It is an essential document used in naval architecture and ship design to analyze a vessel's stability, buoyancy, and trim.

This video shows how to determine the Assumed Position and its practical use in Celestial Navigation. It includes a brief discussion on how to use AP to determine LOP by celestial observation.

Assumed Position, AP, is a chosen or hypothetical position used primarily in celestial navigation when calculating a ship’s position based on observations of celestial bodies. It is typically not an actual or fixed location but a theoretical one chosen for ease of computation, often determined using the Marcq Saint-Hilaire method with the help of Sight Reduction Tables, Pub. No. 249.

This video defines the ship's lightweight, deadweight, and displacement. Determine the value of displacement using a hydrostatic table.

Lightweight - is the weight of the ship when completely empty. It is a mass of a ship with all of its structures including all steel, decks, cargo gears, and machinery with boilers topped up to working level.

Deadweight – is a measure of how much mass or weight a ship is carrying or can safely carry. The sum of all the weights of cargo, fuel, lubricating oil, fresh water, water ballast, stores, crew, passengers, and effects. It does not include the weight of the ship.

Displacement – is the weight of the volume of water that a ship displaces or the weight of the water that a ship pushes aside when she is floating.

This video shows how to calculate the amount of cargo that can be loaded in each ship's cargo hold. It involves manual calculations about the percentage capacity of each hold.

It covers draft restrictions and the ship is sailing from summer to winter zone with density corrections.
