Aims

To develop knowledge and understanding of:

A1 - Refrigeration systems for cargo preservation, gas liquefaction and air conditioning systems.
A2 - Application of theory in practice for deeper comprehension of marine engines, Engine balancing and
vibrations.

Outline Of Syllabus

Revision of relevant thermodynamic theory relevant to engines, refrigeration and psychrometry.

Operational principles of 2 and 4-stroke engines. Engine types, classification of marine engines, design considerations, engine thermodynamic cycles; exhaust and flue gas analysis; exhaust emissions and their control; fuels and fuel systems; balancing, noise and vibration: calculation of torsional vibration modes and natural frequencies; engine test analysis.


Marine refrigeration and air-conditioning, theoretical concepts, practical applications and hardware. Refrigeration for cold-storage and air-conditioning; vapour compression cycles, gas compression cycles, flash chamber cycle; compressors, evaporators and condensers.


Air conditioning: Humidity definitions, the psychometric chart, wet and dry bulb temperature, comfort charts, types of air conditioning system, Gibbs-Dalton law, recirculation ratios and contact factors.

Transport of liquefied gases: sea transport of LNG, types of LG carriers, safety, insulation, containment systems, boil-off treatment

Teaching Rationale And Relationship

The module will consist of recordings and lectures/problem classes with accompanying slides and tutorial sheets, provided to support guided learning. This provides an easy and accessible way for students to assimilate the knowledge content and define the scope of each of the syllabus topics.

Lecture/tutorial sessions are used to discuss the taught material and go through worked examples and case-studies.

The independent study time is essential for students to work through the recorded lecture material, supported with reading and tutorial question practice in their own time and at their own pace. Some of this time is dedicated to conducting formative assessment with full solutions provided to assessment questions to inform student learning and self- monitor progress through the material.

The laboratory class provides an opportunity for practical application of some of the taught material. It develops practical skills and demonstrates the relevance of the taught material. In addition it highlights the differences between pure theory and practical application and provides the students with the opportunity to develop systematic scientific methods, including data collection, recording and data analysis under time-limited conditions.

Formative Assessments

Formative Assessment is an assessment which develops your skills in being assessed, allows for you to receive feedback, and prepares you for being assessed. However, it does not count to your final mark.

Assessment Rationale And Relationship

Examinations afford students an opportunity to demonstrate knowledge, understanding and possession of subject specific and key skills. The medium also allows students to demonstrate intended learning outcomes across a wide range of topics within a syllabus under time-limited conditions, this being a valuable metric for any subsequent employer. The exams also afford students an opportunity to demonstrate numeracy and literacy and associated cognitive skills. One of the examinations
(1.5hr) focusses on the student experience in the laboratory (IKO1,3;
ISO1,3,4) and the other (2.0hr) examines the LO's across the full range of the rest of the syllabus (IKO1-5; ISO1-5).
