Lloyd’s Register is hosting a Workshop on Structural Safety and Infrastructure Management from 1.30 to 6 pm on Wednesday 24 May 2017 at the General Committee Room in 71 Fenchurch St, Central London. This Workshop addresses challenges raised by London Infrastructure Plan 2050, i.e., how to maintain buildings, energy and transport infrastructure that constitute the basic pillars for providing social and economic benefits to a growing London. It features talks by a panel of seven renown experts, discussions and a poster exhibition showcasing fourteen related projects.

Key challenges in managing the increasing demand on London’s infrastructure

The natural consequences of an increasing demand in operational and environmental loads are rapid ageing and deterioration of infrastructure. This workshop reports on current needs of our infrastructure to remain effective and structurally safe, and how monitoring systems and reliability models can contribute to:

  • a more efficient infrastructure design, assessment, monitoring and management,
  • maintain current infrastructure stock in operation while minimizing risks,
  • reduce infrastructure costs and demand for non-renewable and carbon intensive resources while maintaining or improving safety levels.

Target audience

Policy makers, owners, operators, managers, research scientists, engineers and practitioners interested in life cycle maintenance, risk and probabilistic analysis of engineering structures and structural health monitoring.

There is no participation fee associated with the workshop. We encourage you to register early as room capacity is limited to 60 spaces. Places will be allocated on a first come, first served basis.

Talk on “Thoughts about the Risks in Adopting Risk-Based Strategies”

What is risk assessment? A look at risk assessment processes. Quantified v Semi-quantitative v judgement. Limitations of simplistic 5×5 matrix methods and ways to overcome these. Can risk assessment be effective when examining resilience? Dealing with legacy infrastructure – risk based examinations of assets v periodicity based examinations. But that’s a routine, steady state thing – what about resilience, catastrophic risk? Think Malahide Viaduct and its implications on Network Rail…
Risk-based strategies: these can reduce infrastructure costs by focussing on priorities and so reducing demand for interventions – including non-renewable and carbon intensive resources. These strategies can maintain and improve safety levels BUT care needs taken not to ignore low priorities, rare occurrences and residual risk! Tips: Watch out for how ‘risk’ can be a misnomer – scour risk at bridges example where we tend to look at the likelihood of a scour but not the consequences. Watch out for how uncertainties and unknowns can lead to risk-averse decisions – meaning a loss in service performance. We need to be more intelligent here – it’s an old truth that 100% safety can be achieved by stopping everything!

Talk on “Resilient Infrastructure: the Role of Structural Health Monitoring”

Following the closure of the Forth Road Bridge, structural health monitoring (SHM) technology provided vital support to engineering staff enabling the bridge to be reopened after a very short time, and was referenced positively in Scottish Parliamentary proceedings. This capability of SHM is potentially the most important application for UK infrastructure likely to affected by degradation or extreme loading. The nature of resilience and the role of  SHM are explored using some recent example applications in the UK.

Application areas include offshore installations, ship structures, bridges, tunnels, buildings, roadway traffic systems and space structures as well as for management of natural hazards.

Talk on “Decision Theoretical Framework to Offshore Structural Integrity Management”

The presentation provides an overview and appraisal of major developments in risk informed structural integrity management for offshore installations together with a discussion of their merits and the challenges which still lie ahead. Starting point is taken in a selected overview of research and development contributions which have formed the basis for Risk based Inspection Planning (RBI) as we know it today. Thereafter an outline of the methodical basis for risk informed structural systems integrity management, i.e. the Bayesian decision analysis, is provided in summary. The main focus is here directed on RBI for offshore facilities subject to fatigue damages. New ideas and methodical frameworks in the area of Value of Information in Structural Health Monitoring, robustness and resilience modeling of structural systems are introduced and it is outlined how these may adequately be utilized to enhance Structural Integrity Management (SIM).

Talk on “Data Centric Engineering”

This talk will describe the emergence of data centric engineering as a means of quantifying and propagating uncertainty in data rich descriptions of the integrity of structural assets. Advances in network sensor technology provide the means to construct structures such as bridges with high density integrated distributed sensors providing unprecedented levels of spatial and temporal information about the time evolving nature of the integrity of the structure. This allows for the first time the development of rigorous probabilistic and statistical representations of the overall signature of the asset and its evolution thus opening up the possibility of probabilistic online safety monitoring and management.
