Technology – Intro – Control systems basics
• Topside: Human interface • Communication link
• Subsea: Control and monitoring

Technology – Signal on power (modems)
• Traditional • Enhancements
• Follows the power – simple system solutions
Technology - Ethernet
• Topside • Subsea – Network – Instrumentation
• Limited distances
Technology - Fiber
• Not so new anymore – Little loss – Long stepouts – COTS
• Mainstream • Sufficient capacity – state of the art
Architecture - Topologies
• 1 to n modems on powerline Topside

Architecture - Redundancy
• A and B sides • Separate A and B pods for the distribution units
• Signal on power for backup communication

Functionality - network
• KISS • Learn from Internet/Intranet and telecom
• Capacity
Functionality - Topside vs. Subsea
• Handle data as close to the source as sensible, but no closer
Functionality - Access
• Standardized users with different access rights • Remote access
Future FMC vision – The Invisible Dream – “All Subsea”
Future • How to use existing technology subsea – Marinization – Packing – Obsolescence handling
• Distance
FMC vision –
• Capacity
The Invisible Dream – “All Subsea”
• Standardization
