SCOPE OF WORK
Oil & Gas Pipeline Transportation
One of SECON strengths is to provide services for the entire lifecycle of a Pipeline Project.
This includes Feasibility Study, Alignment Survey, Soil Investigation, Cadastral Survey, Right of Use (ROU) Acquisition as per Government Act, Statutory Clearances, Environmental Impact Assessment and Management (EIA/EMP), Social Impact and Rehabilitation Assessment (RA), Disaster Management studies including Environmental Clearances and assistance during construction/laying of pipeline.
Reconnaissance and Route Optimization using Satellite Images/ Base Map
Desktop study of maps / satellite imagery and identification of alternate pipeline corridors and optimization of best alternative.
Reconnaissance survey and establishment of flag control points at definable and major crossing locations
Assessment of terrain, geology, soil strata (visual), land use, forest area, land cost, weather, administrative jurisdiction and related information
Centerline and Detailed Route Survey
- Establishment of trench centerline
- Staking and survey measurements for angles, distances and ground profile
- Preparation of strip plan, alignment, and crossing drawings
- Collection of Meteorological data, population density, utility and administrative jurisdiction
Soil Stratification and Resistivity Survey
- Stratification survey of soil / rock along pipeline by auger boring at specified intervals upto 3m depth and visual engineering classification
- Auger boring at major crossing locations upto 5m depth and testing of soil samples in a laboratory.
- Comprehensive corrosion survey, comprising resistivity survey, physical and chemical analysis of soil and water samples
Geotechnical, Hydrographic and Hydrological Investigations for HDD Crossing
- Deep boring for major river / creek crossings both in bed and at tanks
- Hydrological and hydrographic investigations for crossing locations (water table, aquifer studies, flow pattern, high flood level, bathymetry of river and sea bed, silt pattern, scour depth, sub-bottom profiling)
- Testing of soil samples at laboratory
ROU Acquisition, Permitting and Clearance
- Cadastral survey and land information, ownership details, validation and data generation for ROU acquisition under the Pipeline Act
- Data management system for property inventory, evaluation of land, crops, and fertility loss for land compensation
- Assistance to Competent Authority (CA) for 3(1), 6(1) notification, serving of notices, recording of interest, payment of compensation
- Assistance in site selection and evaluation for stations and other facilities.
- Permitting and clearance from various statutory authorities, road, rail lines, foreign pipelines, underground and over-ground utilities, forest, and defense lands
EIA and EMP Studies
- Extensive data collection and analysis
- Socio-economic and environmental impact studies
- Pollution monitoring, risk analysis, and disaster management
- Preparation of comprehensive EIA and EMP reports for Pollution Control Board and environmental clearances
GIS Based Software Development
- Generation of comprehensive GIS/MIS database integrating engineering and land information
- Creation of seamless drawings / route maps with overlays for alignment sheets, stratification, corrosion survey, land information, and crossing details
- Database for disaster management and upgradation of same to facilitate operation and maintenance
- Development of ROU Software – this is a customised Web Enabled GIS based software for Right of Use/Way property management and administration of this Complex Process which have included the compilation and data management more than 10,000,000 parcels compiled by SECON as of date
- Development of Fully Automated Auto Cad based Alignment Sheet generators for Survey, Engineering, Construction and As-Built Alignment Sheets.
