Deliverables
Reformat existing data -> SSDM
Minimum additional work for data processors
Process should be simple enough so that personnel without GIS knowledge can produce it easily
Process should be integrated in existing workflow and should use all available data: data from DeepOcean’s production database (project database) and Project related files stored on the File System
GIS Delivery: Initial considerations
SSDM Conceptual Framework
SSDM Implementation
Extension of existing Project database
Development of FME Workbench
Extension of the existing in-house application (DODBMS)
Simplified System Architecture
Seabed Survey / Pipeline Inspection Ilustration
Terrain modelwith pipe
Visual inspectionDTM/Cross profiles of pipe using Dual-head MBE
Pipeline inspection - ROV
External inspection of pipeline condition Damages to concrete coating Level of cathodic protection Freespan detection – lay comfort of pipeline Burial condition of trenched or gravel dumped pipeline
