Updated 26 May 2023

Marine Engineering - STCW III/ 1 CoC Name of respondent, organisation and role:
Competency/ Module: Marine Engineering: Naval Architecture (Management Level)      
Knowledge, understanding and proficiency Recommendation of working group regarding the outcome and objective. Rationale Action required
Outcome 1: Calculate small and large angle stability in marine vessels Keep Relevant See sub-outcome actions
1.1 Inclining Experiment Modernise We must contextualise this topic in a stability context, to allow candidates to apply their knowledge using the tools they have at sea and showing how this will be practically applied on board. Include practical applications of inclining experiments, using stability data given to the vessel and use of loading computers, relevant software and/or simulators
1.2 GZ Curves Modernise We must contextualise this topic in a stability context, to allow candidates to apply their knowledge using the tools they have at sea and showing how this will be practically applied on board. Include the data available on board for intact stability criteria, damage stability criteria, and minimum GM and max KG tables. This should highlight the practical uses of this information as opposed to memorising theories.
1.3 Wall Sided Formula Modernise Unnecessary to teach calculations as the loading computer is used so there is no need for quick calculations. More focus can be placed on the practical impacts of this formula. Remove calculations using wall sided formula. Include more focus on the use of loading computers, or relevant software, and the importance of water-plane area.
1.4 Longitudinal Stability Modernise We need to include information on parametric resonance and standardise the method of calculation of trim and stability. Add information on Parametric Resonance. Use moments from Aft perpendicular as a standard for all teaching, learning and assessments.
1.5 Bilging Modernise We must contextualise this topic in a stability context, to allow candidates to apply their knowledge using the tools they have at sea and showing how this will be practically applied on board. Include reading and interpreting down flooding points and down flooding angles from stability books/drawings. Modernise using ship-shape theoretical examples. Simplify box-shape calculations.
1.6 Simpsons Rule Keep Relevant None
Outcome 2 Calculate ship powering and resistance from model test data Keep Relevant See sub-outcome actions
2.1 Shear force and bending moment diagrams Modernise We must contextualise this topic to allow candidates to apply their knowledge using the tools they have at sea and showing how this will be practically applied on board. Use stability information supplied to the vessel including design principles and sea trial data for this outcome as opposed to manual calculations.
2.2 Shear force and bending moment calculations Modernise We must contextualise this topic to allow candidates to apply their knowledge using the tools they have at sea and showing how this will be practically applied on board. Remove calculations of Shear Forces and Bending Moments. Focus on the allowable seagoing and still water Shear Forces & Bending Moments.
2.3 Frictional Resistance Modernise The underlying calculations are unnecessary for seagoing staff, this work is done in the design stage. However, there is a practical impact of these principles for energy efficiency requirements and stability assessments using failure modes. Teach the practical impacts to shipping, including emerging regulations and the impact on energy efficiency requirements and stability assessments using failure modes. Remove the requirement to teach the underlying calculations.
2.4 Residual Resistance Modernise    
2.5 Model testing Modernise    
2.6 Admiralty Coefficient Modernise    
Outcome 3: Calculate ship fuel consumption from propeller dimensions Keep Relevant See sub-outcome actions
3.1 Fuel consumption Modernise We must contextualise this topic to allow candidates to apply their knowledge using the tools they have at sea and showing how this will be practically applied on board. Use stability information supplied to the vessel including design principles and sea trial data for this outcome. Financial and environmental consequences of fuel consumption & routing: use of software for calculating these values including weather criteria.
3.2 Propeller calculations involving slip, thrust, torque and efficiency Keep Relevant None
3.3 Relationship between powers Keep Relevant None
3.4 Propeller cavitation Keep Relevant None
3.5 Rudder balance and principal forces Keep Relevant None
3.6 Rudder problems involving angle of heel Keep Relevant None
Outcome 4: Discuss constructional details used to resist stress Keep Relevant See sub-outcome actions
4.1 Stresses in ship’s structures Keep Relevant None
4.2 Structural components Keep Relevant None
4.3 Fore and aft end construction Keep Relevant None
4.4 Framing Keep Relevant None
4.5 Ship’s cross sections REMOVE This is covered in a level four outcome. Remove as is a duplication of a level four outcome.
4.6 Bulkheads Keep Relevant None
4.7 Rudders/ Control Systems Modernise This outcome requires modernisation to include other forms of control systems such as azimuth thrusters or water/ pump jet technology. Change “Rudders” to “Control Systems”. This will provide a catch-all sub-outcome that should cover future technological developments.
Proposal submitted by: Any other outcomes for this competency, above and beyond STCW which would be needed due to use of modern technology and impact of future fuels onboard:    
  Objective Reason Why Action required
Cadet Training & Modernisation Working Group Include Human Element Factors throughout the syllabus To provide seafarers with a contextualised understanding of the Human Element in the maritime industry, showing how they can put theory into practice in the work they carry out at sea. Raise awareness throughout the Cadet’s training of the areas in which human element factors will have an impact. Recommendations on where this can be included have been noted throughout the entire syllabus. Not every template has Human Element Factor recommendations but please do add any you feel may have been missed.
Cadet Training & Modernisation Working Group Include Data Science skills throughout the syllabus Data Science Skills (Comprehension, Analysis, Presentation, etc…) are already required within much of the syllabus. A further, specific focus on these skills needs to be taught where relevant. A specific topic will need to be introduced to improve Cadets’ Data Science skills. Practical application of data science skills should be highlighted throughout the syllabus. Not every template has Data Science recommendations but please do add any you feel may have been missed.
Cadet Training & Modernisation Working Group Ensure all outcomes are contextualised to help Cadets understand what they are learning in relation to what they will experience at sea. While some outcomes are intrinsically linked to work carried out at sea, some need to be contextualised to show how they apply to work on board. Where this is the case, it is important to make sure Cadets clearly understand how the outcome relates to work at sea and it is essential to make sure that this context is given with reference to current and future seagoing technologies and practices. Where outcomes do not specifically cover a topic which relates to work carried out at sea, more must be done to contextualise the outcome and make it relevant to the maritime industry, giving specific shipping examples of how the outcome may be applied in a modern shipping context. Not every template has contextualisation recommendations but please do add any you feel may have been missed.
