Project Experience: Marine Surveys
Recent examples of Data Gathering and Route Selection projects executed by INTEC include:
- BP Horn Mountain Pipeline Project - Preparation of survey documentation and selection of contractor, survey supervision, route selection and alignment drawings, geohazard assessment and preparation of regulatory documentation.
- Scarab / Saffron Pipeline Project - Preparation and evaluation of ITT package for Marine Survey, for Barullus Gas Company.
- Gazprom Blue Stream Pipeline Project - Responsible for route selection, bathymetric, geophysical, geotechnical and seismic surveys.
- Shell Malampaya Pipeline Project - Responsible for offshore and onshore route selection, evaluation of seismic hazard analyses, mass gravity flows and other special studies, survey operations (swath bathymetry, sidescan sonar, sub bottom profiling, high resolution seismic, observational ROV, coring and CPT, landfall appraisal and earthquake and active fault line identification.
- Conoco West Natuna Project - Responsible for pipeline routing analysis including bottom roughness analysis, 3D modeling of the seabed based on survey data, calculation of profiles and dredging volumes, preparation of pipeline alignment drawings.
- Oman-India gas pipeline - INTEC scope was to identify and evaluate a feasible pipeline route and alignment. Use of ultra deepwater acoustic technology and specialized geotechnical and geophysical tests were performed, including embedment tests, deepwater coring by ROV, local dredging tests by ROV and video mapping of the shelf breaks on both sides of the route. Later reconnaissance survey was performed using swath techniques to provide a side-scan mosaic of a 5 km wide corridor and landfall survey and mapping. The detailed route survey was then completed, which provided detailed bathymetry along a 1 km wide corridor.
- Iroquois Pipeline Extension Project - In 1999 INTEC was selected to manage a survey across Long Island Sound. The route crossed shorelines with densely populated residential areas, heavy fishing lanes and fishing zones. Marine survey operations were planned and supervised by INTEC.
