Seabed Surveys
• O&G companies spend millions of dollars each year conducting:
- Pipeline route surveys- Rig site surveys- Field development surveys- Debris surveys- Environmental surveys
• The data acquired by these surveys is used for planning purposes, operational support and to manage risks

Traditional Survey DeliverablesHardcopy maps and CAD files and immature GIS projects Survey reports
What is the SSDM?
• A GIS template for Seabed Survey industry- Sweep/Debris Survey - Site Survey- Pipeline Route Survey
• Based on an ESRI Geodatabase format as ESRI ArcGIS this is the de-facto industry standard for spatial data management, mapping and GIS
• Provide core components typically used in Oil & Gas companies’ offshore b dseabed surveys
“Vision is for the industry to have a template/standard for how seabed “Vision is for the industry to have a template/standard for how seabed survey data is delivered to and managed by oil and gas companies”survey data is delivered to and managed by oil and gas companies”
Why the need for the SSDM?
• Typically seabed survey data has been captured and delivered by survey contractors in unstructured CAD or GIS files
- Difficult and costly to manage internally- Difficult to integrate survey data- Difficult to share survey data with Joint Venture Partners- Lack of integration within business workflows
• O&G companies have not previously been proactive in defining a structured data model for how this data can be better managedmodel for how this data can be better managed
• Shell and Woodside had developed and successfully implemented the seabed survey data model (SSDM)
- Numerous surveys successfully delivered- Survey data management workflow in place
• Woodside presented the idea of an industry wide SSDM at the 2009 OGP S&P meeting which was supported and the SSDM “Task Force” was created

• Task force includes representation from the Institute of Marine Contractors (IMCA) through Fugro and DOF Subsea
Work So Far • Four teleconferences between January and August
• Jan 2010 - Shell and Woodside supplied technical specifications to other parties
• May 2010 - Position Paper produced and posted to the OGP website to summarise the task force progress and feedback on the Shell/Woodside SSDM
• July 2010 – OGP Technical Workshop held in Shell Miri office (attended by Bong Khin-Fah and Gareth Wright)
• August 2010 - Material from the t h i l k h f d d t t ktechnical workshop forwarded to task force members for beta testing
• September 2010 – Beta testing feedback being implemented to make SSDM V1 more robust
• October 2010 – Seek endorsement from the OGP S&P committee to release SSDM V1 to industry
• December 2010 – The SSDM task force posted on the OGP site an invitation for additional industry feedback (including software vendors)
• April 2011 – Launch the OGP SSDM V1 at the ESRI PUG
The SSDM Material
• ESRI Personal Geodatabase template
• Data Dictionary
• ArcGIS Stylesheet
• Conceptual data model diagrams
• User and contractor guidelines
• ArcSDE SSDM Implementation Guide
• FAQ’s document
• OGP SSDM guidance note

Seabed Survey Workflow

Survey Planning
• What surveys have been undertaken previously and is this data adequate for the task at hand?
Survey required
Survey Planning
If proposed runlines are generated internally these can also be loaded to the proposed run lines feature class
Surveyrequired
SSDM template used to load the runlines and keysheet can then be forwarded on to survey contractor to populate with data acquired by the survey
Survey keysheet (survey extent) and survey details can be loaded e.g. survey name, survey type etc.
Survey Planning
Geodatabase of data extracted for area of interest!
Have two geodatabases to handover to the contractor:
1. SSDM Geodatabase template with survey keysheet and trackplots loaded
2. Geodatabase of existing survey data coverage (created by the extraction process)

• Provide the data to the enterprise without the need for users to have ArcGIS Desktop e.g. drillers
Summary• The SSDM provides a better framework for managing and utilising seabed survey data
• Better storage and management of seabed survey data provides huge business value to O&G companies
• The SSDM has been proven to work through its use within Shell and Woodside
• SSDM has good survey contractor and software vendor support• SSDM has good survey contractor and software vendor support
• The OGP Seabed Survey Data Model V1 is officially available and can be downloaded from the OGP Geomatics site
• Like all data models the SSDM will evolve – if you are interested in participating then please contact:
