Civil and Offshore Engineering
MRM2502 Civil and Offshore Engineering

Dr Sands & Mrs Chandler Christine Fraser Noble F015 (Top Floor of West Wing)

Course Structure Aims Objectives
To provide an understanding of the scale and range of civil and offshore engineering works, including the techniques used in marine, coastal, estuarine and onshore situations. Objectives This course is intended to enable you to communicate effectively with other professionals and members of the public about aspects of construction in marine and coastal environments.

Asessments Presentation projects (40% total) – Each student (working in groups) will contribute to 2 projects that will be presented by the group to the full class. Each presentation (10%) will be supported by a written summary from each individual student (500 words plus 4 illustrations maximum – 10%). The presentations will be peer ranked. 2 class tests of 30% each. During each test students will write 2 brief reports (from a selection of topics), 1 on a tutor presented topic and 1 on a student presented topic not their own. March 11 & April 22

Talking the Talk Brief Outline of Some Engineering Terms
Weight & Mass Kilograms Force – one of Newton’s laws: Newtons

Equilibrium Consider a book sitting on a table
F If Upwards is positive, then: R-F=0 R=F R Another of Newton’s Laws: To every action there is an equal and opposite reaction.

Consider Book Falling Assume parachute very light
Total upward force = P-F P-F=-ma F – P = ma But F=mg So: mg-P=ma F

Another of Newton’s Laws
A body will remain at rest or continue to move with a constant velocity unless acted upon by an external force.

Stress – Simplistic Approach
Tension Shear

Strain – One Simplistic Definition

The Important Bit Stress relates to the force or load applied to a body. Strain relates to deformation.

Young’s Modulus or Elastic Modulus
σ e

Structural Failure Strength Stiffness Stability Robustness Durability
Other Serviceability

The Legal Framework HSE http://www.hse.gov.uk/ CDM
SEPA Building Regulations

The Important Bit Enabling legislation
The details can change – sometimes a lot. The client (i.e. the person for whom the structure is being built) has duties under the law (except for domestic or very small scale work). Always check on the current situation. The HSE is not always your friend. You need planning permission unless you are the Queen. Your L.A. will usually give you advice.
