Introduction
“Classical” capital dredging projects are disappearing.
Move towards D&C, EPC and DBFM projects.

Introduction
Increasing size of reclamation projects
+
Increasing desire for “ready to use” land (and quickly please)
=
Significant need for ground improvement works

Introduction
Example project – Land reclamation in the Middle East
Reclamation of 14km2
Large surface area site long pumping distances
Difficult subsoil (sabkha deposits and loose sands)
Ground improvement by:
• Dynamic Replacement of subsoil
• Roller compaction of fill and subsoil
• Rapid Impact Compaction of fill

Quality control
Post improvement testing:
• Dynamic Replacement: 3 CPTs per 50x50m area
• Roller compaction: 1 CPT per 50x50m area
• Fill: 1 CPT per 50x50m area, Field density testing during filling
• Zone load testing

Quality control
Total testing in 2 years:
• ~20,000 CPT (excluding progress testing)
• >80 zone load tests
• Large number of classification tests and in situ tests
• Subject to internal and external quality control
• CPT testing require validation based on project criteria
• Determination of stiffness of composite soil in DR areas
• Settlement predictions for each 50x50m area
Need for robust and multifunctional data management and analysistool

Data management system
• Collect data
• Analyse / compare to requirements
• Access to data and analysis results
• Reliable, flexible, automated
• Based on OpenEarth philosophy

File: 01.txtPoor data description:
• What is measured?
• What units?
• What locations?
• Which projection?
• When measured?
• With what instrument?
• With what settings?

Poor data description:
• Projection?
• Transparency?
Recognisable frustrations?
• hmm, what was measured here?• huh, where was it measured exactly?• oops, when was it measured?• aarghh, is there still someone around who knows what was done there?
• ohhh, why does it take so long to collect data!• #$*!, has that data been deleted?!?• ah yeah, yet another data format … again!!!• sigh, this problem must have been solved by someone else before me!
• oh oh, I used an old version of this tool!• euh, what/where is the most recent version of this tool?• why is everybody using a different tool for the same analysis?• oh no, we’ve made the same mistake again!
• WHY CAN’T I BUILD ON THE HERITAGE OF PREVIOUS PROJECTS?

OpenEarth benefits for Van Oord
1. Enables the safe use of a data cloud in combination withlight weight applications
2. Promotes collaboration of specialists from variousdepartments
3. Promotes continuous improvement of approaches/toolsfrom project to project
