Instruction to marine propulsion systems
The document discusses various marine propulsion systems. It describes how ships are typically powered through a propeller connected to an engine that transforms an energy source into mechanical power. Common energy sources discussed include fossil fuels like diesel powering most ships, as well as alternative sources like solar, wind, nuclear, hydrogen, and wave energy being explored. The document also examines different types of engines like steam, diesel, gas turbine, and their use in marine propulsion applications.
Ship Propulsion system
This document discusses ship thrust and propulsion systems. It begins with an overview of how ship thrust is created through the shafting system and connection to the propeller. It then examines the various components of the drive train from the engine to the propeller, including definitions of key power terms. The document also covers topics like shaft alignment, thrust bearings, lubrication, and emissions from marine engines. It provides diagrams to illustrate key concepts and systems.
Lect 9 ship propellers (new)
1. Ship propellers work by sucking in water and accelerating it out in a slipstream, using the change in momentum to generate thrust.
2. Screw propellers have key parts like the blade, hub, tip circle, and define characteristics like pitch. Pitch is the theoretical distance traveled per revolution.
3. Propellers can be fixed pitch or variable pitch (controllable), with the latter allowing control of thrust without changing engine power.
Propulsion system
The intend is to visualize the learners with the mechanism of propulsion system of a ship & various types of propellers used.
Ship Motion and Stresses
Static forces on a ship include internal forces from structural weight and cargo and external static forces from hydrostatic pressure. Dynamic forces result from ship motion at sea, wind and waves, and operating machinery. A ship has six degrees of freedom of motion: rolling, surging, pitching, swaying, heaving, and yawing. Ship motion introduces dynamic forces that cause stresses on the ship's structure. Methods to reduce rolling include bilge keels, passive tanks, controlled passive tanks, active tanks, and fin stabilizers.

Marine Propulsion History and Electric Propulsion & Future Technology
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.
Propeller and Rudder
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

Ship Construction - Rudder Theory
This document summarizes key aspects of rudder theory and design. It discusses how rudders generate force through pressure differences on each side, and how this force has both lift and drag components. It describes different types of rudders based on the position of the center of effort relative to the axis of rotation, including balanced, semi-balanced, and unbalanced rudders. It also discusses rudder construction materials, pintle bearings, and considerations for rudder stock sizing based on the type of rudder.
Ship Construction (Structure Part)
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.
Ship Construction- Bulkhead
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.
MARPOL Annex VI Chapter 4
This document provides an overview of IMO regulations for improving ship energy efficiency, including:

- Ships must undergo surveys and be issued an International Energy Efficiency Certificate verifying compliance with Chapter 4 requirements.
Ship Rudder
This document discusses ship rudders, including:
- Rudders are fitted at the aft end of ships to provide directional control and derive benefit from increased water velocity from the propeller.
- There are three main types of rudders - balanced, unbalanced, and semi-balanced. Balanced rudders have a portion of blade area forward of the stock to reduce torque on the steering gear.
- Size, shape, and type of rudder is governed by the ship's stern shape, required rudder area, steering gear capacity, and service conditions.
- Special rudders like spade rudders, Flettner/Becker rudders, Borg

Basics of-ship-resistance
1. The document discusses the various components of ship resistance including viscous resistance, wave-making resistance, and air resistance.
2. Viscous resistance is affected by factors like Reynolds number and hull shape, with slender hulls reducing the normal component.
3. Wave-making resistance drastically increases above the hull speed as transverse wave length approaches ship length. Bulbous bows can reduce bow wave resistance.
4. Total resistance is calculated from coefficients of viscous, wave-making, and air resistance, with model tests needed to determine wave-making coefficient.
Nuclear submarine tecnology
Nuclear submarines are powered by nuclear reactors which use nuclear fission to generate heat and convert water to steam to power the submarine's propulsion systems. The first nuclear submarine, the USS Nautilus, was launched in 1954. Nuclear submarines have several advantages over conventional submarines such as not needing to surface frequently for air and being able to operate at high speeds for long durations. India has launched its first nuclear submarine, INS Arihant, which carries nuclear missiles and adds to India's credible second-strike nuclear capability.
Sewage treatment plant on a ship

Nuclear propulsion in ships
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.

Fire hazards and precautions on LNG carriers
LNG consists of hydrocarbons that will burn when exposed to air between concentrations of 5-15%, the flammable range. Sources of ignition on LNG carriers include engine rooms, which the carriers are designed to protect against. In the event of a fire, the alarm is activated and fire parties muster. The master advises crew of the situation while maneuvering as required. The chief officer and chief engineer take control of firefighting, starting pumps and isolating the source, in this case by closing the manifold valve. The technique of progressive cooling uses advancing sweeps of spray to cool the fire's surface in early stages when it is fed by thin vapors.

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.
Brown Bag (Roy) - EEDI for LNG Tankers
This document summarizes a study on energy efficiency regulations for LNG carriers. It examines 493 LNG carriers using four main propulsion technologies: steam turbine, dual fuel diesel electric, slow speed diesel with reliquefaction, and main engine gas injection. The study calculates the Energy Efficiency Design Index (EEDI) for each technology both with and without considering methane slip. It finds that current EEDI regulations do not properly account for methane slip and may not incentivize reducing greenhouse gas emissions. The document proposes policy alternatives like setting more stringent EEDI reduction targets, updating the EEDI baseline, including methane slip in calculations, and using correction factors. The conclusions are that the EEDI needs revision to make

A high-Speed Communication System is based on the Design of a Bi-NoC Router, ...
The Network on Chip (NoC) has emerged as an effective
solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate
guaranteed throughput, predictable latency, and equitable
network access, showing significant improvement over previous
designs

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Open Channel Flow: fluid flow with a free surface
Open Channel Flow: This topic focuses on fluid flow with a free surface, such as in rivers, canals, and drainage ditches. Key concepts include the classification of flow types (steady vs. unsteady, uniform vs. non-uniform), hydraulic radius, flow resistance, Manning's equation, critical flow conditions, and energy and momentum principles. It also covers flow measurement techniques, gradually varied flow analysis, and the design of open channels. Understanding these principles is vital for effective water resource management and engineering applications.
Bituminous road construction project based learning report
Road construction is not as easy as it seems to be, it includes various steps and it starts with its designing and
structure including the traffic volume consideration. Then base layer is done by bulldozers and levelers and after
base surface coating has to be done. For giving road a smooth surface with flexibility, Asphalt concrete is used.
Asphalt requires an aggregate sub base material layer, and then a base layer to be put into first place. Asphalt road
construction is formulated to support the heavy traffic load and climatic conditions. It is 100% recyclable and
saving non renewable natural resources.
With the advancement of technology, Asphalt technology gives assurance about the good drainage system and with
skid resistance it can be used where safety is necessary such as outsidethe schools.
The largest use of Asphalt is for making asphalt concrete for road surfaces. It is widely used in airports around the
world due to the sturdiness and ability to be repaired quickly, it is widely used for runways dedicated to aircraft
landing and taking off. Asphalt is normally stored and transported at 150’C or 300’F temperature
