WHAT IS THE UNIT ABOUT?

Unit description

To provide an understanding and working knowledge of resistance and propulsion of

ships. Experimental and theoretical methods are covered with an emphasis on

application to design. Students are shown the theory behind these methods and are

required to demonstrate usage of the methods (both theory and experiment) to

predict resistance and hence propulsion requirements. This unit builds on the

knowledge of fluid mechanics and applies it to practical design scenarios.

Intended Learning Outcomes

On completion of this unit, you will be able to:

1. Estimate, by experimental or basic computational methods, the resistance of

and powering requirement for many marine vessels. Explain the effects of hull

form parameters from basic dimensions (such as beam) to complex hull/fluid

interactions (such as a bulbous bow).

2. Conduct a critical analysis of a research paper on resistance of mono or multi-

hull vessel.

3. Evaluate the process of experimental determination of resistance and powering

of an existing hull design and associated propulsion system. Demonstrate the

skills necessary to perform these tests and report on the findings with reference

to errors due to accuracy and repeatability issues. Achieve all of these aims

within a team of engineers.

4. Explain the principles of propeller and water-jet operation and carry out a

practical propeller design. Specifically students must be able to generate,

analyse and implement within the design process relationships between thrust,

torque, cycles per minute and speed of advance for multiple propulsion system

options.

5. Explain the causes of cavitation, its detrimental effects and how to take steps to

prevent it occurring on a propeller and water-jet system.

How your final result is determined

To pass this unit, you need to demonstrate your attainment of each of the Intended

Learning Outcomes.

The grade that you receive for this unit will be determined by a committee of

examiners. The raw marks that you receive from each piece of assessable material will

be combined in order to determine a letter grade for the unit (see Assessment

Schedule for per cent weighting). The raw marks may undergo a scaling process.

Assessments will be awarded a grade from HD to NN in accordance to a criterion based

grading system where applicable (see BE Course Rules). Where applicable, this will be

based on an assessment matrix (to be handed out before the assignment due date),

which identifies the level of performance by indicative characteristics associated with

each level against each criterion. The criterion based grading system will provide

students with the following grades for each assignment, with the final grade obtained by

combining the grades of the assessments in line with allocated weighting.

Grade HD- to HD+ DN- to DN+ CR- to CR+ PP- to PP+ NN (Fail)

Students needs to achieve an overall average of 50% to pass this unit.

Submission of assignments

All assignments, reports, etc. must be completed using the template provided on the

AMC website, unless otherwise specified by the lecturer. All coursework must have

the AMC Assignment Cover Sheet attached.

All assignments and reports must be typed and completed using Word, Excel,

approved Engineering drawing software and include the relevant theory,

illustrations, results, analysis, and conclusion.

Group reports must be signed by all participants.

Assignments and reports must be placed in the lecturer’s assignment box by the due

dates (ground floor in the Swanson Building).

Electronic submissions are not acceptable (unless otherwise instructed by the

lecturer). The assessed work will be returned during lecture or as agreed between the

students and the lecturer.

Please remember that you are responsible for lodging your coursework on or before

the due date. We strongly recommend that you keep a copy. Even in the most

‘perfect’ of systems, items sometimes go astray.

Page 9 JEE33 Resistance & Propulsion

Requests for extensions

Extensions will only be granted on medical or compassionate grounds. Requests for

extensions should be made via email to the lecturer prior to the due date. Medical

certificates or other evidence must be included (electronically or the hard copy

mailed) and must contain information which justifies the extension sought.

Penalties Late assignments which have not been granted an extension will, at the lecturer’s

discretion, be penalised by deducting ten per cent of total marks for each day overdue.

Assignments submitted more than five days late will normally not be accepted by the

lecturer.

Failure to adhere with the WH&S standards whilst taking part in any assessed

activity that involves field trips and/or that requires the use of UTAS or AMC

facilities will result in the following penalties:

first offense - 5% penalty (applicable to the whole team in team projects);

second offense by student (or another member of the same team in team

projects) - 20% penalty (applicable to the whole team in team projects); and

third offense - a fail grade in the assessment.

The University library provides information on presentation of assignments, including

referencing styles and should be referred to when completing tasks in this unit.

Please read the following statement on plagiarism. Should you require clarification

please see your unit coordinator or lecturer.

Plagiarism

Plagiarism is a form of cheating. It is taking and using someone else's

thoughts, writings or inventions and representing them as your own; for

example, using an author's words without putting them in quotation

marks and citing the source, using an author's ideas without proper

acknowledgment and citation, copying another student's work.

If you have any doubts about how to refer to the work of others in your

assignments, please consult your lecturer or tutor for relevant referencing

guidelines. You may also find the Academic Honesty site on MyLO of

assistance.

The intentional copying of someone else’s work as one’s own is a serious

offence punishable by penalties that may range from a fine or

deduction/cancellation of marks and, in the most serious of cases, to

exclusion from a unit, a course or the University.

The University and any persons authorised by the University may

submit your assessable works to a plagiarism checking service, to

obtain a report on possible instances of plagiarism. Assessable

works may also be included in a reference database. It is a

condition of this arrangement that the original author’s

permission is required before a work within the database can be

viewed.

For further information on this statement and general referencing guidelines, see the

Plagiarism and Academic Integrity page on the University web site or the Academic

Honesty site on MyLO.

Academic misconduct

Academic misconduct includes cheating, plagiarism, allowing another student to copy

work for an assignment or an examination, and any other conduct by which a student:

a. seeks to gain, for themselves or for any other person, any academic advantage

or advancement to which they or that other person are not entitled; or

b. improperly disadvantages any other student.

Students engaging in any form of academic misconduct may be dealt with under the

Ordinance of Student Discipline, and this can include imposition of penalties that

range from a deduction/cancellation of marks to exclusion from a unit or the

University. Details of penalties that can be imposed are available in Ordinance 9:

Student Discipline – Part 3 Academic Misconduct.
