Breaking Tradition: How SSDM and ArcGIS are Modernizing Subsea Survey

Taylor Brown (GIS Analyst, AUV Group)Katherine Butcher (Survey Ops Manager, SSDM Taskforce Member)

Seabed Survey Data Model (SSDM)

Presentation Goals

• What is SSDM?

• How does it differ from historic data deliverables?

• Survey contractor benefits for SSDM & GIS implementation?

• Operator benefits from SSDM & GIS implementation?

• Room for improvement?

• Next steps?

What is SSDM?

Seabed Survey Data Model

• Subsea Survey Geophysical and Hydrographic Data Management & Deliverables Template

• 2011 Release by IOGP • Geomatics Group Geo-

Information Subcommittee

• SSDM Task Force

• IOGP & Operator “Flavors”

DOF Subsea – ESRI PUG – 10 April 2015 4

SSDM Purpose & Inception• Offshore Field Development & Data Management Tool

• Seabed & Shallow Sub-Surface Features (10’s of metres, i.e. not for Exploration)

• Standardize data for a full project life cycle

DOF Subsea – ESRI PUG – 10 April 2015 5

Data Model Structure

• File or Personal Geodatabase• 4 Feature Datasets

• 30 Feature Classes

• Hydrographic, Geophysical & Environmental Survey Templates

•Subsea Infrastructure Siting:• Feature Locations & Attributes

• Geohazards

• Environmental Conditions

Data Delivery Streamlining

DOF Subsea – ESRI PUG – 10 April 2015 17

Survey Contractor• Conduct Survey• Process & Interpret Data• Assemble SSDM

SSDM Delivery to Operator• Transfer GDB

Enterprise System• Integration w/ existing database• Dissemination to geologists, engineers, managers

Operator Data Management
