The Offshore Site Investigation and Geotechnics (OSIG) Group of the SUT is pleased to announce its 7th International Conference, ‘Integrated Geotechnologies – Present and Future’. This conference will continue the aims of this established series, started in 1979, of disseminating and communicating the latest developments in all aspects of marine geotechnology.

The needs of the offshore industry have evolved substantially since the first conference held in 1979. While foundation developments continue to be important, there is now greater emphasis on integrating marine geology, geophysics and geotechnics. New challenges are being presented in geohazard assessments and geotechnical aspects of renewable energy, deepwater developments, floating production, pipelines, subsea tie backs and new environmental conditions.

Exciting developments for this conference included hosting the inaugural Bramlette McClelland lecture, organised by the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) in commemoration of one of the pioneers of offshore geotechnical engineering. The conference also held combined sessions featuring papers from special offshore issues of Géotechnique and Near Surface Geophysics, both leading journals in their respective specialist fields.
