Subsea pipeline designers are taking on more ambitious projects as the demand for gas increases and the distance between the source of supply and the market place increases. This has driven national pipeline transmission companies and O&G operators to seek more efficient routes and improved infrastructure networks. To meet these requirements major pipelines are being routed across deepwater areas and tectonic boundaries which were technically not possible ten years ago. Pipeline engineers are therefore faced with the challenge of designing a pipeline that passes through a variety of environments including landfalls, shallow continental margins, potentially unstable steep continental slopes and across Abyssal plains. This paper describes the survey techniques (geophysical/geotechnical/geological) that should be used to ensure that there is a continuous coverage of data for the various environments encountered along a typical route. The paper also explains that the data acquisition stage is part of the process to ensure that a comprehensive integrated earth science data set is acquired for Front End Engineering Design (FEED).
