ABSTRACT

BP Angola has formalised the documentation of this process in terms of Geotechnical Engineering and Geohazard Mitigation (GGM) reports which are produced at key milestones; when new data are acquired

or the proposed infrastructure changes significantly. The GGM reports act as baseline information which reflect the project team’s collective state of knowledge of the shallow sub-surface geotechnical conditions and geohazards at a given time. The reports are used to ensure that contractors bidding for work do so on an equal footing and that subsequent designs are consistent. Ultimately the reports provide a reference for seabed-related problems throughout the life of the development through to decommissioning. Figure 1 illustrates the relationship between the project schedule, geo-data collection and the production of GGM reports.
