Vessel based solutions for the acquisition of geotechnical data in subsea site investigations

摘要

This extended abstract describes a presentation that was given at the Society for Underwater Technology/ASEG 1st Joint Technical Seminar, 25 March 2010, Perth. It discusses the role and technical capability of multi-purpose support vessels in providing solutions in performing comprehensive geotechnical site investigations. There is a growing awareness of the benefits to be gained in being able to integrate geotechnical results with the geophysical data during the later acquisition phases of seabed investigations. This presentation highlights the growing trend to want to integrate and be able to easily access the various existing desk top study findings and the geophysical data sets right through to the geotechnical phase offshore. This is being made easier by the current and future adoption by oil and gas operators of seabed survey GIS data models. Having data accurately stored in a universally recognized format by means of GIS will make it much easier to display and use seabed visualisation systems to get the best benefits of data integration.
