Subsea Charts – About me:
Senior Data Processor and Cartographer
Alessandro Devic, experienced senior data processor and cartographer with 15 years of proven history of working in the oil&gas industry.
I offer offshore and office data processing services with a focus on multibeam interpretation/processing, custom cartographic, computer aided drafting, data collection geographic information systems, data processing, data management, and field operations services.
Subsea Charts – What I do:
Data Processor, Cartoghrapher, EIVA, Autochart
Interpretation of seabed and sub-seabed data for project planning and execution with the aim of industry specific software’s like EIVA Naviedit, Model, Visualsoft, Qinsy, AutoChart, InChart, ArcMAP, QGIS.
Over the years I worked on various projects which include: Pre-Construction Survey, Pre-lay Survey, As Laid & As Built Survey, pre-post trenching surveys Out of Strainghtness , Pipeline Surveys.
Offline inspections using VisualSoft, Pipeline inspection including eventing: anodes counting, CP readings, anomalies etc… I will provide detail-oriented support of bathymetric data processing management and make sure all cartographic deliverables meet the client requirements and are at the leading edge of industry standards.
My Deliverables:
From data analysis: hydrographic, topographic , geotechnical , geophysical, engineering, environmental surveys of multibeam, pipetracker, sidescan sonar data, to the creation of the following industry standard products:
- DTM (.xyz) files as per client request bin size.
- Charts as alignment sheets or site survey ( DWG, PDF ).
- 5/8 point listings for pipeline surveys, delivered in professional Excel presentations.
- Events listing.
- Multibeam Calibration.
- SSDM: handling of metadata for feature classes of survey deliverables (trackplots, isopaches, soundings, contours, samplings) embed the metadata in the client’s ESRI geodatabase using GIS.
Creation of the base chart: example
#1 Horizontal
- Local and geographical grid.
- As-built position of the pipeline.
- As-Found position of the pipeline with KP at 500m intervals.
- Bathymetric contours.
- Political boundaries, man-made.
#2 Vertical Profile
- Horizontal scale 1:4000 vertical scale 1:200.
- KP grid lines at 500 m intervals, depth grid lines at 5m interval.
- As-built longitudinal profile of the pipeline, inner and outer seabed profile.
- As-found longitudinal profile of the pipeline.
- As-Found position of the pipeline with KP at 500m intervals.
- Bathymetric contours.
- Political boundaries, man-made features.
#3 Events along the route
- Product specs.
- Anodes.
- Debries&damages.
- Crossings.
- Geological features.
- Freespans and burials.
- Trenches.
- Rockdumps.
