Introduction
The workshop will focus on non-hydrostatic pore water pressure (overpressure) in seabed sediments and the role it plays in offshore geohazards. This is a significant geohazards problem that plays a critical role in the creation of submarine landslides and the safe and reliable design of offshore infrastructure. The overall goal of the workshop is for attendees to share, and for the organizers to document, the state-of-knowledge, ongoing research, and the consequences for analysis and design of sediment overpressures. To this end our understanding of overpressure in seabed sediments requires the collective research capabilities of a multidisciplinary panel of experts. The workshop will bring together such experts from the disciplines of geosciences, geotechnical engineering, geophysics and instrumentation engineering. The workshop outcomes are expected to include: 1) an increased linkage between scientific and engineering communities involved in seabed sediment characterization, research and engineering design, 2) publication and dissemination of workshop proceedings, 3) an executive summary for external audiences to delineate the critical nature of the problem and its impact on society, 4) work plans and defined partnerships for future research collaboration and needs, and 5) training of future engineers and scientists for international collaborative research in offshore geohazards through attendance of students.
Location for Technical Sessions
All technical sessions will be held at the Ullevaal Business Class AS (UBC) center. This facility is located across the street from NGI and within the Ullevaal Stadion football stadium. The street address is Sognsveien 75, Oslo (Stadium entrance J). It is a short walk from the Ullevaal Stadion T-bane (metro) stop. T-bane trains run from downtown Oslo every few minutes during the business day. Details on scheduling is available at www.trafikanten.no. Generally it takes about 15 minutes from downtown Oslo to the Ullevaal Stadion station.
