Description

This unit will develop students' knowledge of hydrostatics fundamentals and concepts of statical stability and trim of intact and damaged vessels. The practical implications and applications of hydrostatic concepts are introduced to enable students to generate all relevant stability data required for both design and development, and operational purposes. A working knowledge of stability regulations will also be introduced and developed.

Prerequisite Rule

Students must pass 1 units from ENS1101

Learning Outcomes

On completion of this unit students should be able to:

  1. Calculate hydrostatic data for any hull form, and predict the influence of hull form parameters on a vessels stability characteristics.
  2. Produce a trim and stability booklet compliant with relevant standards.
  3. Conduct an inclining experiment in accordance with industry best practice.
  4. Examine the principles of hydrostatic parameters and explain their implications.
  5. Analyse a vessels response to any loading condition from lever and moment curves.
  6. Calculate and assess a vessels damage stability response.

Unit Content

  1. Heeling Moments and Angles and Free Surface Effects: Heeling forces, heeling moment curves, angle of list, angle of loll, heeling due to wind forces, free surface effect and moments, heeling effects due to high-speed turning.
  2. The Intact Stability Booklet: Contents and purpose, required information, basic trim and stability data, stability criteria and instructional information, standard loading conditions.
  3. Tabular Methods of Integration: Simpsons Rules, intermediate ordinates, application of the parallel axis theorem, application of Simpsons Rules to volumes, centroids and moments of inertia.
  4. Mass Addition, Removal and Transfer: Centre of gravity, shift in centre of gravity due to addition (or removal) of mass, shift in centre of gravity due to movement of on-board mass, effect of a suspended mass.
  5. Geometry of Surface Vessels: The lines drawing, hull dimensions, reference datum, dimensions and coefficients of form, displacement and weight relationships, Bonjean curves.
  6. Elementary Principles of Trim: LCF, TPC, longitudinal metacentre, trimming moment, MCTC, longitudinal transfer of onboard mass, change in trim due to addition/removal of small masses, change in drafts due to change in trim, determination of drafts after addition/removal of large masses, change in trim due to change in density, FWA, draft marks.
  7. The Inclining Experiment: The principle, guidance for conducting an inclining test, inclining test procedure.
  8. The Partially-Afloat Condition: The dry-docking case, minimum GM0 and maximum trim for dry-docking, grounding of one point of the keel.
  9. Elementary Principles of Transverse Intact Stability: Equilibrium, metacentric height and transverse metacentre, curves of statical stability, centre of buoyancy, the wall-sided expression, KN and cross curves of stability.
  10. Damage Stability: Subdivision, subdivision terminologies & definitions, bilging effects on stability and trim, IMO subdivision requirements for passenger vessels, International Maritime Organization (IMO) subdivision requirements for dry-cargo vessels.

Disability Standards for Education (Commonwealth 2005)

For the purposes of considering a request for Reasonable Adjustments under the Disability Standards for Education (Commonwealth 2005), inherent requirements for this subject are articulated in the Unit Description, Learning Outcomes and Assessment Requirements of this entry. The University is dedicated to provide support to those with special requirements. Further details on the support for students with disabilities or medical conditions can be found at the Access and Inclusion website.

Assessment

Students please note: The marks and grades received by students on assessments may be subject to further moderation. Informal vivas may be conducted as part of an assessment task, where staff require further information to confirm the learning outcomes have been met. All marks and grades are to be considered provisional until endorsed by the relevant School Progression Panel.

Academic Integrity

Integrity is a core value at Edith Cowan University, and it is expected that ECU students complete their assessment tasks honestly and with acknowledgement of other people's work as well as any generative artificial intelligence tools that may have been used. This means that assessment tasks must be completed individually (unless it is an authorised group assessment task) and any sources used must be referenced.

Breaches of academic integrity can include:

Plagiarism

Copying the words, ideas or creative works of other people or generative artificial intelligence tools, without referencing in accordance with stated University requirements. Students need to seek approval from the Unit Coordinator within the first week of study if they intend to use some of their previous work in an assessment task (self-plagiarism).

Unauthorised collaboration (collusion)

Working with other students and submitting the same or substantially similar work or portions of work when an individual submission was required. This includes students knowingly providing others with copies of their own work to use in the same or similar assessment task(s).

Contract cheating

Organising a friend, a family member, another student or an external person or organisation (e.g. through an online website) to complete or substantially edit or refine part or all of an assessment task(s) on their behalf.

Cheating in an exam

Using or having access to unauthorised materials in an exam or test.

Serious outcomes may be imposed if a student is found to have committed one of these breaches, up to and including expulsion from the University for repeated or serious acts.

ECU's policies and more information about academic integrity can be found on the student academic integrity website.

All commencing ECU students are required to complete the Academic Integrity Module.

Assessment Extension

In some circumstances, Students may apply to their Unit Coordinator to extend the due date of their Assessment Task(s) in accordance with ECU's Assessment, Examination and Moderation Procedures - for more information visit https://askus2.ecu.edu.au/s/article/000001386.

Special Consideration

Students may apply for Special Consideration in respect of a final unit grade, where their achievement was affected by Exceptional Circumstances as set out in the Assessment, Examination and Moderation Procedures - for more information visit https://askus2.ecu.edu.au/s/article/000003318.
