Marine Craft Concept Design

Learning Outcomes

Subject Specific Practical Skills

Having successfully completed this module you will be able to:

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

Knowledge and Understanding

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

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

Transferable and Generic Skills

Having successfully completed this module you will be able to:

• Evaluate competing design drivers and alternatives to make a reasoned technical choice.
• Work as a group on a concept design assignment.

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 and learning methods

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.

Resources & Reading list

General Resources

Various papers. in Transactions of RINA and SNAME

Relevant statutory regulations. such as LSA, accommodation, load lines (freeboard), HSC code, Large Yacht code, SOLAS, Small Commercial Vessels code, etc.

Database. of relevant marine craft and design information.

Assessment strategy

Referral Method: Report submission and supporting calculations for a chosen substantive technical element of the

design (e.g. stability, powering or structures calculations) and an improved General Arrangement drawing (i.e. improving their own contribution to previous collective effort). This will be assessed via a structured viva where a series of questions will be asked and responses noted. = 100%
