This document provides an introduction to ship structure design. It discusses that ship structures have evolved over time as engineering understanding has improved. The key functions of ship structures are to provide strength, stiffness, watertight integrity, subdivision, and payload support. Ship structural design must consider various requirements related to hull shape, cargo arrangements, safety, cost efficiency and other factors. The role of structural designers involves synthesis, analysis, and optimization across different stages of the design process.
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.
1. The document discusses the analysis of statically determinate structures. It describes how to idealize structures by representing joints as pinned or fixed connections.
2. The principle of superposition states that the effects of separate loads on a structure can be added to determine the total effects. This requires structures to behave linearly.
3. Statically determinate structures have as many equations of equilibrium as there are unknown internal forces. These equations can be written and solved to find member forces.
1. Structures must support loads safely and economically while accounting for factors like material properties, loading types, and structural response.
2. A structural analysis determines member forces and displacements using mechanics, while the design process involves successive refinements.
3. Structures must be designed to support dead loads from structural elements and attachments, as well as live loads from occupancy and environmental forces like wind and earthquakes that are specified by building codes.
Bridge rehabilitation covers many complex engineering problems and economic issues. It involves repairing, strengthening, or replacing existing bridges to improve their structural condition and functional capabilities. The main factors that can lead to bridge deterioration include inner bridge factors like design flaws; traffic load factors from increasing vehicle loads and speeds; weather and environmental factors such as pollution and temperature fluctuations; and inadequate maintenance. Bridge rehabilitation aims to address deterioration from these sources and extend the usable life of bridges.

The document discusses the design of elevated water tanks, noting that they must be carefully designed to withstand various loads and stresses while preventing leakage, and outlines the objective of developing an expert system to aid in the design of liquid retaining structures using visual basic by accounting for factors like configuration, material, and loads. It also examines the loads that act on reinforced concrete chimneys and discusses joints in liquid retaining structures.
Shell structures are thin curved structures that are efficient at using materials. They can be found in nature and are used for industrial and architectural structures like silos, tanks, and roofs. Shells are difficult to analyze due to their complex behavior under loads. Different types of shells include elliptic paraboloids, hyperbolic paraboloids, and circular cylinders. Buckling is an instability issue for shells where they change shape under load. Several methods are used to analyze shells including finite element analysis, membrane theory, and bending theory equations.

During a full scale test of a freefall lifeboat on a permanent production installation offshore Norway in June 2005, weaknesses in the superstructure was experienced. The lifeboat had been type approved by Norwegian authorities, based on design and testing requirements in international codes. As a result of the discovery, The Norwegian Oil Industry Association - OLF, on behalf of its member companies, initiated a full investigation of all 16 freefall lifeboat types on the Norwegian Continental Shelf (NCS). During a four year programme of investigations, tests and analysis, several weaknesses have been disclosed. The outcome of the Norwegian Lifeboat project (LBP) has lead to proposed remedial actions for existing lifeboats and the development of a new standard for future freefall lifeboats. The project has been carried out in co-operation with unions, lifeboat manufacturers and authorities. It has been a unique life boat review project, and has reduced the risk of a potential evacuation situation offshore.

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
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 MODELijaia
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%.
2. Intro to Ship Structures
• There are many types of structures. The
definition of the word structure (Webster’s) is;
a. manner of building, constructing, or organizing
b. something built or constructed, as a building or dam
c. the arrangement or interrelation of all the parts of a
whole; manner of organization or construction: the
structure of the atom, the structure of society
d. something composed of interrelated parts forming
an organism or an organization
3. Intro to Ship Structures
• Here is an example of some parts of a ship
structure:
4. Intro to Ship Structures
• An example of civil structures;
5. Intro to Ship Structures
• A ship structure is quite a distinct type of
structure, especially in the arrangement of
components
• But also in the many unique constraints and
regulatory context that influence ship structural
design
• This course will focus on the technical elements
of structural design and analysis of ships
6. Guesstimation
• One of the aims of the course is for the students to develop the
ability to make an educated guess
• Such guesses are not wild or random. Educated guesses are based
on sound reasoning, careful approximation and simplification of the
problem
• Basic laws of mechanics are considered to determine what
fundamental principle might govern the outcome
• The ability to make quick assessments is the mark of an expert and
is a crucial skill to avoid costly and dangerous mistakes
• Such guesses never remove the need for detailed calculations, but
they do improve the quality and efficiency of the engineering
7. Background
• Humans have been constructing structures for a
long time. A structure is a tool for carrying and
protecting
• Ship structures have evolved like all other types
of structures (buildings, aircraft, bridges)
• Design was once purely a craft. Design is evolving
as we understand more about the structure itself
and the environment that we subject it to
9. The Aim Of Structural Design
• The purpose of structural design of ships is to
design the most efficient structure for
purpose. Here efficiency is taken to mean a
wide array of factors.
• The structural designer must be aware of the
effects of their decision on the cost and
maintenance of the ship
10. Purpose of Ship Structures
• The structure of a ship or ocean platform has 3
principal functions:
a. Strength (resist weight, environmental forces – waves + )
b. Stiffness (resist deflections – allow ship/equipment to
function)
c. Water tight integrity (stay floating)
• There are two other important functions
a. provide subdivision (tolerance to damage of 1,3 above)
b. support payloads
14. Structural Design Requirements
• The particular arrangement of the structure is done to suit
a variety of demands:
a. Hull is shaped (reduce resistance, reduce motions, reduce ice
forces, increase ice forces, reduce noise)
b. Holds are arranged for holding/loading cargo
c. Holds are arranged for holding/installing engines
d. Superstructure is arranged for accommodation/navigation
e. All structure is arranged for build-ability/maintainability
f. All structure is arranged for safety
g. All structure is arranged for low cost
15. Structural Design Requirements
• Ships are a class of structures called "semi-
monocoque“
• In a pure monocoque, all the strength comes from the
outer shell ("coque" in french)
• To contrast, in "skin-onframe” construction, the loads
are all borne by a structure of framing under the skin
• In ships, the skin is structurally integral with the
framing which supports it, with the skin providing a
substantial portion of the overall strength

17. Role of the Designer
• The role of the structural designer changes in each stage of
ship design.
• Designer must not go into more detail than in required at
current stage.
• At all stages the designer must satisfied with the overall
architecture of the ship such that a solution can be
achieved within the required levels of cost, weight, space
and levels of reliability
• Margins must also be specifies taking into account
uncertainties at each design stage
18. Evolution of the Design
• The structure design moves through a series of
evolutionary phases e.g. in initial design several
different design options will be considered in
sufficient detail to allow for identifying feasible
design options
• These options are refined and in later phases,
they are considered in greater depth until the
most efficient structure can be indentified
19. Types of Structural Work
• Ship structural specialists are involved in a variety
of work:
– Design
– Analysis
– Construction
– Maintenance
– Repair
– Regulation
20. Synthesis Analysis & Optimization
• Synthesis: Development of a system from its
components while ensuring compatibility between
components, loads and in-service functions
• Analysis: Is the proof that synthesised system will
provide functions that will satisfy reliability
requirements
• Optimisation: Is the process of ensuring that analysed
system is most efficient and economic
21. Historical Perspective
• A knowledge about the history of ship design is
important for understanding the design process
• Until 1970s wave loading was assessed using a static
wave balance with wave height taken as L/20. Although
this resulted in conservative estimations this
assumption was severe but not extreme. This was used
together with classical methods to check for buckling in
stiffeners and buckling.
22. Historical Perspective
• In the 1950s and 60s, methods involving elasto-plastic
techniques were formalised. A large margin of 5.0 was
applied for this case, while a margin of 2.0 was required for
column buckling case against L/20 wave loading.
• In this period there was no explicit method for assessing
fatigue in design. For the first all welded ships, all ships
designed achieved over 20 years of service life and were
limited by fatigue at around 23-25 years.
23. Historical Perspective
• In the 1950s and 1960s brittle fracture was seen as a
problem due to poor steel quality, this was solved by the
introduction of notch tough steels
• In the 1970s two major beak through took place, one was
the use of stochastic techniques and rigid body dynamics to
calculate wave bending. The other was a method for
assessing the ultimate strength of the hull girder as a
complete entity rather than in parts
• Additionally FEA became more readily available for detailed
analysis.
24. Current Design
• Following changes in the design process in the
1970s examples of recent successful structures
have come about. Examples Include the UK Tribal
and Type 22 classes
• Reason for successful designs include the greater
analysis that was carried out along with larger
margins used in areas of uncertainty
26. Current Design
• Hulls should be designed according to realistic life
expectations. Circumstances are likely to change
through the ships life, regardless of what is hopes
in initial requirements
• From experience it is shown that 25 years is a
practical life span for a ship and hulls should be
designed to last that long without imposing too
much on the maintainers.
27. Practical Designs
• All aspects of the design process from loadings to
the environment are non-linear and thus difficult
to model. The skill of the designer lies in their
ability to chose the simplest models on the parts
of the design experience tells them to be most
important. They should also be able to use past
experience to validate approximate models
28. Practical Designs
• Over the last 30 years, the rational approach
has gained prominence. This approach uses
techniques from probability and statistics
coupled with advancements in structural
analysis software's to pursue objectives with a
larger degree of sophistication.
29. Engineering Design
• Design, analysis, construction and regulation are separate
specialties
• In the 1950 tabulated requirements were found in Class Rules.
By the 70s all codes had changed to include prescriptive algebra
• New trends are towards "LRFD - load and resistance factored
design", "risk based design" and "goal based design“
• Current practice in large (novel) projects make extensive use of
"scenario based" design, with HAZIDs (hazard identification and
mitigation).
30. Practical Designs
• While embracing new technology it is important
to be fully aware of their pitfalls and to use them
within the range of their limitations.
• The results from modern analytical techniques
should be compared with past successful practice
and any deviations be clearly explained.
Ships have to sail the seas, other civil buildings do not
While almost all Naval Architects get involved in some structural issues, a few focus
on the area and tend to be involved in more advanced issues. This course aims to
have you develop your ‘feel’ as well as your knowledge of structures. In other words,
you should work at developing you “Engineering Judgment” in the area of ship
structures.
