Ship Structural Design and Production

Learning Outcomes

Transferable and Generic Skills

• Use commercial software in design context.

Knowledge and Understanding

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

• The construction of a mid-ship section.
• The effect of production activities on planning and management functions.
• The application of slender beam theory for the analysis of ship structures.
• The role of Classification Societies and Registration Authorities.
• The concept of productivity, ship production efficiency and machine utilisation.
• How shipyard facilities and machines are organised and the manner in which these influence the various production stages.
• Classification Society rules governing local structural design and global hull girder longitudinal strength.

Subject Specific Intellectual and Research Skills

Having successfully completed this module you will be able to:

• Derivation of activity networks for planning purposes.
• Use theoretical principles provided in other lectures in a practical design environment.
• Cultivate skilful application of associated methods to a variety of structures and loads (ie knowing which method to apply for a particular structure/loading case).
• Understand the principles of structural response to a variety of static loads.
• Apply Classification society Rules to design a midship section.

Learning Outcomes

Having successfully completed this module you will be able to:

• C1/M1 In the longitudinal strength assignment the students treat the ship as a slender beam and loaded based on the hydrostatics of the ship. In the Midship section assignment the students assess the material contained in the ship and its ability to withstand the shear force of the slender beam. C2 For both the Longitudinal and midship assignments the students demonstrate their understanding of beam theory and their ability to analyse the ship as such, which is a critical aspect of ship design and safety. C4/M4 As part of the ship production assignment students should find, critically review, and use literature to select processes and equipment necessary for the production of ship structures. C13/M13 For the ship production assignment students must research and select equipment and technology for the effective production of ship structures, providing realistic data for production planning. C15/M15 For the ship production assignment students must undertake a production plan examining the parallelisation of processes and the use of critical path analysis to identify bottlenecks in the production process. C16/M16 The two design assignments are completed in pairs and the production assignment is completed as a group of 4 or 5. The students need to divide up the tasks required for each assignment to complete them effectively. Peer review is often used for the production assignment to aid the marking process.

Ship Production

• Background into various types of shipyards and overall layout criteria.
• Plate and section pre-treatment; marking; cutting and forming.
• Fabrication activities including fairing, sub-assembly and panel line techniques.
• Berth activities including advance outfitting and module building practices.
• Information system requirements, shipyard standards and planning activities.

Ship Production Management

• This module will be coordinated with the complementary part 2 15 credit “Engineering Management and Law” [EM&L] module FEEG2006. Five of the EM&L module credits will be awarded for management practice within the context of ship production. Management aspects such as project management, teamworking, budgetary performance, communications will be assessed via the EM&L module.
• Ship building management systems and theory such as Product-orientated Work Breakdown Structure (PWBS); work and method study analysis; Network analysis and Critical Path Analysis

Ship Design for Strength

• Weight, buoyancy and load distributions.
• Still water analysis – shear force, bending moment, slope and deflection; stresses.
• Quasi static analysis of a ship poised on a wave.
• Approximate methods and regulations in brief.
• Cross section properties including effects of different materials.
• Effect of adding/subtracting material to cross section.

Midship Section Design

• Midship section – Use of Lloyds classification society rules to determine structural requirements of specified vessel, work to include:
• Complete local structure to Lloyds Rules.
• Determine midship section modulus.
• Assess longitudinal strength.
• Model midship section in Lloyds RuleCalc.
• Modify model to meet Lloyds requirements.

Longitudinal Strength design

• Derivation of still water bending moment (SWBM) for cargo vessel for a range of loading conditions.

Teaching methods include

• 1 Introductory lecture
• 12 Lectures on production
• 5 lectures on Ship Structures (Longitudinal and Midship Strength).
• 22 hrs of supervised design office sessions incorporating an introductory lecture.
• 4 lectures on ship production management (provided under management module).
• 6 x 1hr management tutorials (provided under management module).

Learning activities include

• Individual work on ship calculations/examples.
• Individual work on using ship design software.
• Directed reading/independent learning.
• Report-writing (Coursework).
