7 CIRIA Guide Onshore &Offshore UXO Risks 2009 Land Based CIRIA Guide (C681) 2014 RH DHV and 6 Alpha appointed (C 754) Simon Cooke and Dr Nick Cooper - lead authors 12 month contract - completed May 2015 published ~ Feb 2016 Drew upon the principles of the terrestrial guide and incorporated best offshore UXO risk management practice Takes account of renewables and other offshore schemes It has UK focus yet EU application It is not intended as a technical guide for UXO professionals or EOD experts Add company logo here

8 Guide Preview - C754 Main Elements Background (Chapters 2-4) UXO in the Marine Environment The near and offshore environments Sources and types of UXO Legislation and regulation including HSE UXO Risk Management Framework (Chapters 5-8) UXO threat and risk management principles Threat Assessment Risk Assessment Risk Management Strategy and a selection of options

9 Guide Preview - C754 Main Elements UXO Risk Mitigation (Chapters 9 and 10) Roles and Responsibilities of UXO Specialists - UXO Consultants, EOD Contractors and Surveyors Delivery of UXO Risk Management Services Conclusions and Recommendations (Chapter 11) Assess the threat and risks R = P x C Reduce risks ALARP (Law) Strategy - survey for and avoid UXO if at all possible

10 5 Core Principles UXO Risk Management Threat Assessment Desk Study What type of UXO? Risk Assessment Risk Management Share Transfer Mitigate Tolerate/Carry Risk Mitigation Geophysical UXO Survey Avoidance Verification Render Safe (Destroy) ALARP Sign-off

12 UXO Risk Management Generic Application

13 Marine Geophysical UXO Survey The guides recommend a joint approach between independent UXO and survey specialists Survey factors are presented (e.g. types of UXO, position, shape, mass, materials etc.) Survey platforms are discussed (e.g. vessels, ROV, AUVs) Data Capture i.e. equipment and techniques are discussed (e.g. MBES, SSS, SBP, MAG, PI MAG, MAG CONE) Data interpretation factors are considered (e.g. experienced UXO specialists are required to interpret processed data Techniques
