Calculate, assess and report on vessel trim and stability

Formats and tools

Unit Description
Reconstruct the unit from the xml and display it as an HTML page.
Assessment Tool
an assessor resource that builds a framework for writing an assessment tool
Assessment Template
generate a spreadsheet for marking this unit in a classroom environment. Put student names in the top row and check them off as they demonstrate competenece for each of the unit's elements and performance criteria.
Assessment Matrix
a slightly different format than the assessment template. A spreadsheet with unit names, elements and performance criteria in separate columns. Put assessment names in column headings to track which performance criteria each one covers. Good for ensuring that you've covered every one of the performance criteria with your assessment instrument (all assessement tools together).
Wiki Markup
mark up the unit in a wiki markup codes, ready to copy and paste into a wiki page. The output will work in most wikis but is designed to work particularly well as a Wikiversity learning project.
Evidence Guide
create an evidence guide for workplace assessment and RPL applicants
Competency Mapping Template
Unit of Competency Mapping – Information for Teachers/Assessors – Information for Learners. A template for developing assessments for a unit, which will help you to create valid, fair and reliable assessments for the unit, ready to give to trainers and students
Observation Checklist
create an observation checklist for workplace assessment and RPL applicants. This is similar to the evidence guide above, but a little shorter and friendlier on your printer. You will also need to create a seperate Assessor Marking Guide for guidelines on gathering evidence and a list of key points for each activity observed using the unit's range statement, required skills and evidence required (see the unit's html page for details)

Self Assessment Survey
A form for students to assess thier current skill levels against each of the unit's performance criteria. Cut and paste into a web document or print and distribute in hard copy.
Moodle Outcomes
Create a csv file of the unit's performance criteria to import into a moodle course as outcomes, ready to associate with each of your assignments. Here's a quick 'how to' for importing these into moodle 2.x

Elements and Performance Criteria


Plan and prepare stability testing


Applicable stability criteria for class of vessel and its operations are identified and confirmed against regulatory requirements


Differences between Uniform Shipping Laws (USL) and National Standard for Commercial Vessels (NSCV) standards for assessing stability are identified and applied to survey plan as required


Information and data is used to establish and verify stability characteristics required for safe operation


Types of stability related hazards that may occur during all types of operations are identified


Range of intended and/or likely vessel loading conditions are accurately identified and their impact on stability is assessed


Calculate vessel trim and stability


Simplified stability calculations are performed to assess compliance with applicable stability criteria


Stability assessment methods for equivalent solutions are applied as necessary according to regulatory requirements


Trim, draughts and freeboard are measured accurately to safely and efficiently allow assessment of compliance with criteria


Effects of weight distribution that may compromise vessel safety are included in stability assessment


Computer-based stability programs are used as appropriate to assist with assessing compliance


Results are verified to confirm compliance


Vessel is not put at risk during assessment


Apply tests, assessments and theories to confirm compliance


Tests and assessments that could assist to confirm stability compliance are verified and carried out according to safety instructions


Small angle stability theories are used to establish metacentric height (GM) through transverse movement of weights across vessel deck


Causes of inaccuracies and limitations of assumptions in tests, assessments and theories are interpreted accurately and considered in stability assessment report


Identify other impacts on stability calculations


Types and effects of damage on vessel stability are identified and considered according to regulatory requirements


Damage stability considerations are accurately identified and effect of damage is correctly quantified


Operational impact on stability is identified and considered in compliance assessment


Vessel safety management plan is reviewed to ensure known or likely impacts on stability are included


Document and report findings


Records are maintained and reports are prepared according to regulatory and organisational guidelines


Survey report is completed according to regulatory requirements
