Marine Craft Concept Design

Learning Outcomes

Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

• The functions and applications of marine craft concept design methodologies.
• Estimate the additions which have to be made to the powering of ships in service, for accurate design estimation of installed power.

Learning Outcomes

Having successfully completed this module you will be able to:

• C1/M1 Demonstrate in the final report the application of a comprehensive knowledge of engineering principles to ship concept design, including critical awareness of new developments in high speed craft design and expectations of society/customers of such vessels. C2/M2 Through interpretation of the vessel design brief students evaluate available data and using engineering judgement around information that may be uncertain students complete a concept design and analyse their design to reach substantiated conclusions regarding its power requirement, structural integrity, seakeeping performance and stability. This is demonstrated in the final report and submitted drawings. In evaluating their designs, students discuss the limitations of the techniques employed. C3 Students select appropriate computational/analytical techniques to model the powering and propulsion of the vessel designed, recognising the limitations of the techniques through comparison of alternative methods and discussion in the final report. C4/M4 Students select and evaluate technical literature (including statutory regulations and Classification Society rules) relevant to aspects of their designs (such as safety, structures, engines, layout, dimensions, other equipment) to solve their overall design problem/brief. This is evidenced in their final report and drawings. C5/M5 The vessel design produced by each group demonstrates (in the final report and drawings) solutions to a complex design brief, incorporating societal, user, business and customer needs. This includes consideration of relevant safety requirements and codes of practice/industry standards (IMO HSC code, LR SSC rules) and environmental (Tier III/ECA requirements) and commercial, cultural and commercial matters as specified in the design brief. C6 Students apply an integrated approach to the solution of the design problem/brief C7 Groups evaluate the environmental impact of their designs through compliance with relevant SOLAS and ECA requirements for emissions and relevant local wash/MCA requirements. Students are strongly encouraged to investigate and implement low- or zero-Carbon solutions for the powering of their designs. C15/M15 The final report and drawings demonstrate management of the vessel concept design, as a group exercise, requiring coordination of effort. The designs must be costed and demonstrate compliance with relevant legal standards and considerations. C13 Groups must select appropriate material for construction of their vessel, equipment onboard (engine, HVAC, lifesaving, etc) as well as techniques for powering analysis (e.g. regression equation, first principles, numerical) and discuss and comment on their limitations. C16/M16 Students work in groups and the final report and drawings are assessed as a group. Students complete 3 peer review forms throughout the module, evaluating their own and the group's performance. C17 Students submit a group report (written communication), drawings and also a short presentation of their designs. They also participate in an informal feedback session ('desktop review') with industry experts at the end of the module, and 'design review interviews' with module staff 3 times. This enables them to demonstrate communication on complex engineering matters (their concept designs) with technical and non-technical audiences (not all industry experts are naval architects, or have knowledge of high-speed craft).

Subject Specific Practical Skills

Having successfully completed this module you will be able to:

• Create a concept design and carry out relevant checks to verify its safety, feasibility, and sustainabilty given an outline specification.
• Carry out calculations for the derivation of ship powering components in service.

Transferable and Generic Skills

Having successfully completed this module you will be able to:

• Present and justify a design solution developed from a design specification to a technical and semi-technical audience.
• Work as a group and individually as part of the group on a concept design assignment.
• Evaluate competing design drivers and alternatives to make a reasoned technical choice.

Subject Specific Intellectual and Research Skills

Having successfully completed this module you will be able to:

• Apply the methodologies and tools used in the marine craft concept design process to the concept design of a marine craft.

The course entails the development of a marine craft design to concept stage, taking due account of

the following aspects:

• Owners requirements/mission
• Outline specification, including requirements for cargo mass/volume/passenger number, speed, range and operating environment
• Dimensions
• Preliminary stability check
• Preliminary powering estimates including additions necessary for estimation of powering margins (air resistance, roughness, fouling and added resistance in waves)
• Masses and centres estimates
• Body plan
• Hydrostatics/stability/floodable length and damaged stability assessments
• Powering/propulsion machinery selection
• Preliminary investigation of auxiliary machinery requirements (including HVAC systems)
• Structure: concept midship section
• Seakeeping: preliminary assessment of motions, added resistance, limits of operation
• Statutory regulations: application of relevant regulations (e.g. SOLAS, HSC code, MARPOL as relevant)
• Sustainability, environmental and safety issues
• Layout/GA: to include cargo/passenger areas, officer/crew accommodation and engine room layout

Teaching methods include

Supervised weekly design office sessions supported by lectures in specific aspects and guest lecturers from industry where appropriate.

• Learning activities include
• Individual and group work on marine craft design calculations.
• Individual and group work on producing a concept ship general arrangement plan.
