Topic:
Managing multiple functions of the subsurface
Form of presentation:
Free Session Proposal
Duration:
90 Minutes
In order to realize our ambition on climate, energy and a comfortable living environment the subsurface will be used more intensively in the near future. Rapid innovations and economic circumstances give the opportunity to increase our use of the subsurface. This increase in multiple uses creates a pressure on the subsurface which needs to be managed. Unforeseen events occur in every-day projects and can have negative social, cost or environmental impacts and limit other uses in the subsurface. This was the reason for a preliminary Dutch study and recent publication „Unexpected events in the subsurface“ (TCB, Witteveen+Bos and Deltares). This study implies a broad analysis of causes and consequences combined with lessons learned from illustrated cases. It resulted in insights with respect to the negative impact of unforeseen events and the factors that play an important role in occurrence and prevention. Looking at traditional tendering (knowledge sharing, risk evaluation and liability) and High Reliable Organizations helps us to find possible solutions to manage unforeseen events. The preliminary study has shown that knowledge availability and sharing, risk sharing during tendering, transparency and attitude toward unforeseen events and good governance play an important role in enhancing our grip on unforeseen events. The session organizers wish to enrich the Dutch experiences and lessons learned with experiences of professionals from other countries represented on AquaConsoil.

Theme: managing multiple functions of the subsurface
In order to realize our ambition on climate, energy and a comfortable living environment the subsurface will be used more intensively in the near future. Rapid innovations and economic circumstances give the opportunity to increase our use of the subsurface. This increase in multiple use creates a pressure on the subsurface which needs to be managed. Unforeseen events occur in every-day projects and can have negative social, cost or environmental impacts and limit other uses in the subsurface. This was the reason for a preliminary Dutch study and recent publication „Unexpected events in the subsurface“ (TCB, Witteveen+Bos and Deltares).
This study implies a broad analysis of causes and consequences combined with lessons learned from illustrated cases. It resulted in insights with respect to the negative impact of unforeseen events and the factors that play an important role in occurrence and prevention. Looking at traditional tendering (knowledge sharing, risk evaluation and liability) and High Reliable Organizations helps us to find possible solutions to manage unforeseen events. The preliminary study has shown that knowledge availability and sharing, risk sharing during tendering, transparency and attitude toward unforeseen events and good governance play an important role in enhancing our grip on unforeseen events.
In this session we want to enrich the Dutch experiences and lessons learned with experiences of professionals from other countries represented on Aquaconsoil. We will present some Dutch examples of projects dealing with unforeseen events and discuss the lessons learned with the international audience. Furthermore, we want to invite participants on Aquaconsoil to bring in there own experiences into the session. To promote the latter, we intend to organize a contest during Aquaconsoil on the best example of an unforeseen event in a project in the subsurface and approach to deal with it. Participants will be invited by us, ideally 1 or 2 days in advance of the session (depending on de programming of Aquaconsoil) to fill in a short form to present their example. If possible we will incorporate these examples in the session, inviting the contributors to explain and discuss their case.
