| Programme
This conference continues
the aims of this established series, started in 1979, of
disseminating and communicating the latest developments in all
aspects of marine geotechnology through technical sessions, which
will run over three days. These sessions will consist of keynote
lectures, presentations and question and answer sessions, along with
poster exhibitions.
A conference dinner,
sponsored by Fugro, will be given for all delegates, as well a
cocktail reception, sponsored by Gardline, and there will be daily
