The document discusses the history of shipyards and shipbuilding. It notes that some of the earliest known shipyards date back to 2400 BC in India and ancient Egypt. It describes the evolution of ship designs over time, from early sail types like lateen rigs used by Romans and in the Mediterranean, to the dominance of square rigging on ocean-going vessels. The document also discusses how ship technology and naval architecture advanced alongside social evolution, enabling expansion of trade and changes in how societies were organized, particularly with the rise of slave-powered ships and later steam-powered vessels. It recommends the book it draws from for further information on the intertwined history of ships and society.

Centennial College

Yunyeong Kim came to Toronto to study English and noticed that students at the International Language Academy of Canada were very passionate about learning English. He started practicing English as much as possible to achieve his future goals. To overcome his fear of heights, he visited the Grand Canyon and walked across the Sky Walk, a transparent bridge over the canyon. This helped him feel capable of taking on any challenges. When he began studying at Centennial College, Malcolm X's biography inspired him to keep overcoming difficulties. In his last semester, a kind professor helped Kim gain confidence in his business studies by listening to his thoughts. Kim graduated with all A+ grades and his certificate reminds him of his accomplishments and confidence to continue his business education.

Ship powering performance – learning from the challenges faced by owners

John Wills

This document summarizes challenges ship owners face regarding powering performance of their vessels. It describes how performance is a complex issue with multiple criteria and stakeholders having different focuses. The paper explores recent challenges owners have faced and provides recommendations for best practices regarding technical specifications, trials, monitoring performance in service, and supporting tools. It emphasizes the need for establishing calibrated performance reference values and leveraging lessons learned to improve decision making and communications between technical and operations departments.

Nuclear propulsion in ships

Hassan Moursy

Nuclear reactors were first developed for naval propulsion in the 1940s and the first nuclear-powered submarine, the USS Nautilus, launched in 1955. Over 140 ships have since been powered by more than 180 small nuclear reactors, accumulating over 12,000 reactor years of operation at sea. Nuclear power is well-suited for naval vessels that need to operate for long periods without refueling or for powerful submarine propulsion. Reactors contain over 100 tons of shielding and use steam to drive turbines that power the ship and propellers, operating independently of the atmosphere to allow extended underwater missions. Naval reactors undergo repeated power changes and meet high safety and quality standards for long-term operation with inaccessible internals.

Basic Geometric Concepts

Varun Mohan

This document discusses basic geometric concepts and properties related to ship design and stability. It defines key reference planes and dimensions used in ship plans. Reference planes include the waterline, centerline, and perpendiculars. Dimensions include length, breadth, draft, depth and volume. Ship motions such as surge, sway, heave, roll, pitch and yaw are also defined. The document then discusses coefficients of form, displacement, weight, buoyancy, centers of gravity/buoyancy/floatation, metacenters, and how these factors influence a ship's stability. Free surface effect on partially-filled tanks is also mentioned.

The document discusses handling big data in ship performance and navigation monitoring. It presents a data handling framework that includes developing digital models from data clusters, using principal component analysis to analyze the clusters, and extracting information to reduce parameters while preserving information. The framework allows for data projection, sensor fault detection, integrity verification from other sources, and data visualization to support decision making. The talk outlines developing these techniques to better handle large scale data from ships.

Life and Work of a Naval Architect

Callum Campbell

This document summarizes the key responsibilities of a naval architect. It discusses how naval architects design ship structures, assess stability, analyze resistance and powering needs, evaluate seakeeping performance, and follow a design process. For each area, it provides a brief example and overview of the technical considerations and calculations involved. The overall message is that while kids may dream of designing grand ships, as a naval architect the work involves both large and small projects, using engineering skills to ensure vessels can float and operate safely.

Hull form geometry

Unikl MIMET

This chapter introduces key concepts in hull geometry needed for naval architecture. It discusses how a ship's complicated 3D hull shape is represented graphically through lines drawings, including body, half-breadth, and sheer plans. The chapter also covers how lines plans are converted into numerical tables of offsets and defines important hull geometry terms like length between perpendiculars, block and prismatic coefficients, and rise of floor. Mastering the representation and terminology of hull geometry forms a crucial foundation for further naval architecture studies.

INTRODUCTION TO TERM USED IN NAVAL ARCHITECT

Indian Maritime University, Visakhapatnam

The document defines many key terms used in naval architecture. It begins by explaining terms related to ship dimensions such as forward perpendicular, after perpendicular, and length between perpendiculars. It then defines terms describing ship structure and geometry, including sheer, camber, rise of floor, and tumblehome. Finally, it outlines terms pertaining to ship motion like heave, pitch, surge, roll, and yaw. The document provides a comprehensive overview of technical terminology in naval architecture.

SHIP THEORY : Basics Of Ship Geometry : Lines Plan__by jishnu saji

Jishnu Saji

This document provides an overview of ship geometry and lines plans. It defines key elements of a lines plan including profiles, body plans, and half breadth plans. It explains that lines plans provide a scaled 2D representation of a ship's complex 3D form through descriptive geometry. Various views, components, and their uses are described, including stations, waterlines, buttocks, and diagonals. The document also outlines common uses of lines plans for calculations related to hydrostatics, stability, capacity, structure, and hydrodynamics.

Marine Propulsion History and Electric Propulsion & Future Technology

Mohammud Hanif Dewan M.Phil.

For over 35,000 years, humans propelled boats using paddles. Sails were then discovered around 3000 BC, allowing for longer voyages. In 1770, the steam engine was adapted for ships, initially using paddle wheels for propulsion. In the 19th century, screw propellers and steam turbines were introduced. Diesel engines were developed in the late 19th century and began being used on ships in the early 20th century, providing a highly efficient form of propulsion. Ship propulsion has thus evolved from paddles to sails to steam to diesel over thousands of years.

Types of ships

Mar Cas

Ships come in many types and are used for various purposes. They are generally distinguished from boats based on their large size, distinct shape, and ability to carry cargo or passengers. Some main types of ships include bulk carriers which transport unpackaged bulk goods, container carriers which use intermodal containers, general cargo ships which move packaged goods, vehicle carriers which carry cars and trucks, and passenger ships whose primary function is to carry people. Other ship types specialize in transporting liquids like oil, gas, or chemicals in tankers or transporting perishable goods, fish, animals, or refrigerated items.
