Dynamic Detail Design Mapping for Pipeline Construction through GIS Technology using in-house developed toolbox – TAP Case Study
Part of the proceedings of
One of the most valuable tools in Pipelines Construction is the preparation of reliable Alignment Sheets (ALS). ALS are continuously revised incorporating new information deriving from engineering progress, facilitating timely material procurement and construction. To visualize in handy hardcopies all construction data, a single ALS needs to include five different maps: Plan View, Profile View, Crossing Database, Engineering Database, and MTO Database. All five maps extract data from different datasets regularly updated. GIS based systems allow the integration, collection, revision and management of a huge variety of data to be imported as layers in ALS; designing and managing oil & gas pipelines is made easier through GIS technology. ASPROFOS has been engaged in all phases of Trans-Adriatic Pipeline (TAP): from Environmental and Social Appraisal to FEED local consultancy and construction permits acquisition in Greece (and Albania), and finally Detail Design. TAP shall be the Transit Pipeline of the South European Corridor, and Greece hosts most of its length. For this project a huge amount of data available from previous phases or based on Detailed Engineering progress needed to be incorporated. Data Management, included datasets with almost 5 years of data collection related to Stakeholder Engagement, Environmental Baseline, Social Sensitivities, Constraints, Cadastral, Crossing Details, and Technical Specifications. The datasets needed to be in an ESRI’s UPDM database. A large-scale project like this, led ASPROFOS specialists to identify weak points during ALS preparation and fine-tune the existing procedure. Trying to reduce man-hours and errors, a special tool – AFMapSync - was developed in-house in order to populate, synchronize and export ALS on the fly. ALS preparation and most importantly updating have been significantly simplified through the use of a low cost add-on software, developed based on existing corporate resources, easily adjusted into future projects and customer requirements.
