The keel forms the backbone of the ship and contributes to longitudinal strength. Common keel types include the flat plate keel and bar keel. The hull uses frames, plate floors, and a keel plate to strengthen the structure. A double bottom creates extra strength and space for piping and tanks. Machinery is mounted on reinforced seats with the engine connected to brackets and lugs. The stern frame supports the rudder and propeller shaft. Additional structures like panting beams further reinforce the hull.
This document defines key terms and concepts related to ship stability, including Archimedes' principle, center of gravity, center of buoyancy, metacenter, righting arm, and free surface effect. It explains that a ship is stable when its center of buoyancy is below and to the side of the center of gravity, and that the metacenter indicates the ship's stability based on its position relative to the center of gravity. Additionally, it discusses how stability curves illustrate a ship's righting arm at different angles of heel and how the free surface effect can negatively impact stability when compartments are only partially filled with water.
This document summarizes different types of ships that have developed since 1800 to transport various cargoes. It describes how after World War 2, ships became more specialized to carry only one type of cargo, such as oil tankers, chemical tankers, container ships, and reefers. The document then provides examples and images of these specialized ship types that developed to transport liquids, bulk goods, containers, vehicles, passengers, and for recreation.
This document presents the preliminary design of a 2800 TEU container vessel. It discusses the vessel requirements, trade route between Long Beach, Los Angeles and Colon Container Terminal in Panama and between Colon Container Terminal, Panama and Port of Gebig, Brazil. It outlines the methodology used for the preliminary dimensions, coefficients, lightship weight estimation, stability, lines plan, modeling, resistance calculation, capacity plan, hydrostatics and stability analysis, longitudinal strength and scantling, vibration analysis, propeller and rudder calculations, general arrangement, freeboard calculations and equipment number. The design aims to develop a container vessel that can carry 2800 TEUs at a speed of 20.2 knots to efficiently transport merchandise between the specified ports.
An Offshore supply vessel is a multi-task vessel and has to be designed for many different purposes. This is contrary to most other ships used worldwide. In general, the geographical location where the offshore activity takes place is an important indicator of the choice of supply vessel.
Factors like weather conditions, the amount of equipment needed and the distance from the shore
are important for what properties the vessel should have. The deep-water oilfield market is
becoming more important as the conventional oilfield market in shallow water cannot meet the
energy requirements from the consuming market. The Offshore Supply Vessels (hereafter it is
called OSVs) market is becoming booming and the demand for OSVs has never reached the extent
like today in previous periods.
In this project an offshore supply vessel will be designed according to ABS Rules.

The document provides an overview of key rules and definitions from the Navigation Rules for Marine Law Enforcement Officers. It defines terms like vessel, underway, power-driven and sailing vessels. It outlines lighting requirements and sound signals. It discusses rules for determining risk of collision, taking action to avoid collision, operating in narrow channels, overtaking situations, head-on encounters, and crossing situations.
This document provides an overview of sailing, including why people enjoy sailing, typical sailing lessons, common sailing terms, parts of sailboats, and basic sailing maneuvers. Sailing can be relaxing or competitive, is accessible for all experience and skill levels, and can be enjoyed alone or with others. A typical sailing lesson covers boat rigging, points of sail, maneuvers like tacking and jibing, and safety procedures. The document also includes specifications for two sailboat models - the Flying Scot and Gulfstar 39 sailboat.
Bulkheads are vertical partitions that divide a ship into compartments. There are three main types: watertight, non-watertight, and oiltight bulkheads. Watertight bulkheads are the most important as they subdivide the ship into watertight spaces and prevent flooding. They are constructed of steel plating and vertical stiffeners. Corrugated bulkheads provide strength with less weight by incorporating swelled plates instead of stiffeners. Bulkheads must be watertight at any openings, which are fitted with doors or penetrations sealed with glands. Proper construction and regular inspection of bulkheads and their openings is vital for subdivision and damage stability.
This document summarizes different types and sizes of oil tankers. It describes how crude tankers transport unrefined crude oil and product tankers transport refined products. It outlines the history of oil tankers from the 1850s transporting oil in barrels to the development of modern tankers in the late 1800s. It discusses the era of supertankers in the 1970s that were over 400 meters long and could carry 500,000 tons. The document concludes by categorizing tanker sizes from Panamax and Handysize up to Ultra Large Crude Carriers and Very Large Crude Carriers that can carry over 200,000 tons.
This document contains definitions of various nautical terms related to ship construction and operation. It defines key components of a ship's hull like the keel, frames, and bulkheads. It also explains systems like the rudder, propeller, and auxiliary engine. Finally, it mentions processes such as berthing, launching, sea trials, and anti-fouling painting that are part of preparing a ship for operation.
The document discusses different types of tanker pipeline systems used to load and discharge cargo tanks, including direct line, ring main, and free flow systems. A direct line system is relatively fast and cheaper but less versatile, while a ring main system is more versatile but more expensive and difficult to maintain. A free flow system provides the fastest loading and discharge but poorer segregation between cargo grades. Safety valves are used to prevent undue pressure rises in vessels.
The ship at sea or lying in still water is constantly being subjected to a wide variety of stresses and strains, which result from the action of forces from outside and within the ship.
This document discusses ship propulsion systems. It begins by defining key terms related to propeller horsepower, including:
- Brake Horsepower (BHP): Power output at the engine shaft before reduction gears.
- Shaft Horsepower (SHP): Power output after the reduction gears.
- Delivered Horsepower (DHP): Power delivered to the propeller.
- Thrust Horsepower (THP): Power created by the screw/propeller after losses.
It then discusses propeller types, key parts like the hub and blades, and terminology such as diameter, pitch, revolutions per minute, and whether a propeller is right-handed or left-handed. The
The document discusses the bottom structure of ships, including the functions and types of bottoms, keels, and floors. It provides details on single bottom and double bottom construction. Single bottoms are used in smaller vessels, while larger ships generally have double bottoms for added protection against damage. Double bottoms can be of two types - watertight or dry - and provide both structural reinforcement and tank space. Floors are important transverse structural members that strengthen the bottom plate.
This document discusses ship stability, which is one of the most important aspects to consider for safe navigation. It defines stability as a ship's ability to return to its initial position after being heeled by external forces like wind or waves. The document outlines the concepts of static stability and dynamic stability. It explains that a ship's stability depends on the positions of its center of gravity (G) and metacenter (M), noting there can be stable, neutral, or unstable equilibrium depending on their relative heights. Key terms like metacentric height, GM, KG, and KM are defined in relation to calculating a ship's stability. Safe cargo loading and distribution of weights is emphasized as important for maintaining proper stability.

Basic load out methodologies introductionBruce nguyen
The document provides details on the load out plan using skidding and strand jacks. It assigns responsibilities to various managers for the safe execution of the load out. The key steps include pre-ballasting the barge, installing strand jacks and anchor blocks, pre-tensioning strands, breaking out the structure, and pulling it onto the barge while coordinating with ballasting operations. Safety is the top priority, and specific responsibilities are defined for project management, supervisors, and subcontractors to ensure a safe load out.
Common nautical terms used aboard ships include:
- Knot - a unit of speed equal to one nautical mile per hour. A knot is also a method of fastening line or rope.
- Draft - the depth of a ship below the waterline. Draft marks show the draft on the stern and stem.
- Berth - a mooring space for a vessel. Lines like head lines and spring lines are used to secure a ship in its berth.
- Bearing - a compass direction from one point to another, in degrees or compass points. Navigation relies on taking and plotting bearings.
The document provides information on dry docking procedures for ships, including statutory regulations requiring dry docking at certain intervals. It details the process before, during, and after dry docking, including notifying the dock manager, creating work lists, ensuring stability and draft, connecting services, safety precautions during work, standard and optional repair items, and procedures for entering, working in, and leaving the dry dock. Key steps include surveys; cleaning, painting and inspecting the hull; and overhauling items like anchors, propellers, rudders and valves.
The document summarizes the development of different ship types and their characteristics over time. It discusses the transition from wooden boats powered by sails to modern steel ships powered by engines using coal, oil, and diesel. It describes the emergence of specialized ship types in the 19th-20th centuries like tankers, bulk carriers, container ships, roll-on/roll-off ships, and passenger vessels. It provides details on size classifications and outlines trends in ship design, technology, and regulations around safety, pollution prevention, and efficiency.
