Background

• Offshore Oil & Gas Fields are Expensive to

Develop

A typical field in the US GOM costs between US$2-4 Billion

• High Tech Systems Require More Reliable

Bandwidth

• Safety, hurricane resilience, managing day-to-day
• perations, active monitoring systems, quality of life
• Facilities are Becoming More Automated
• Remote operations and minimal crew sizes are possible

Major production platforms require secure, stable and expandable communications that are only available through fiber:

BP GoM Platform Connection Types

Dynamic Riser Cable with Fiber Distribution Canister for 4 Platforms Subsea Wet-Mate in Deployment Pallet for 3 Platforms Two Methods of Platform Connection

conference & convention

• 3. The main lay vessel overboards the Dynamic Riser Cable (DRC) and

associated equipment

Dynamic Riser Connection Installation

• 1. A pull-in system (winch skid) is installed on the platform
• 2. Support ROV attaches a messenger to the pulling wire
• 4. The DRC is secured topside; the bend limiter connector is secured by

the ROV

• 5. The Main Lay Vessel lays the DRC creating the catenary, followed by

the FDC & branch leg, while the support ROV performs touchdown monitoring

• 6. The Main Lay Vessel lays the final bight, completing the connection

conference & convention

Subsea Wet-Mate Connection Installation

• 1. The support vessel ROV performs an inspection of the

UTA and seabed

• 2. The Main Lay Vessel deploys the Deployment Pallet to

the seabed

• 3. The flying lead is deployed to the seabed, support vessel

ROV performs wet-mate connection

• 4. The Main Lay Vessel completes the branch leg, installs

and lays the final bight, completing the connection

conference & convention

• 62 Pipeline Crossings
• 19 Branching Units
• 21 Repeaters
• ~300 km of Burial
• ~900 km of Surface Lay
• 2 Pre-Laid Shore Ends
• 2 Un-manned Cable Stations

Installation & Coordination

conference & convention

Installation & Coordination

• Adaptation of Existing Equipment
• Standard Cable Lay Procedures & Equipment
• Cable Modeling & Sea Trials
• Topside Coordination
• Simultaneous Operations
• Normal Loading & Transportation Techniques
• No Alteration of Cable Load/Lay Equipment Required
• Traditional Testing & Power Safety Procedures
• Foundation of Standard Submarine Cable Product Handling
• Generate DRC lay procedures
• Dry run DRC equipment overboarding
• Verify subsea equipment deployment procedures
• Practice ROV wetmates, model ROV interventions

Coordination of topside activities required schedule integration early in the process to allow:

• Topside telecom equipment installations
• Installation of riser pull-in equipment
• Network testing

To avoid schedule and POB conflicts with O&G activities which have priority Safety - Safety knowledge & procedures are already ingrained in the existing systems Operational Integrity - Did not require shipboard personnel to learn new lay or testing techniques Schedule - Did not require the generation and review of new procedures by all parties De-conflict installation through constant monitoring of in-field activities such as:

• Drilling Operations in Vicinity of Subsea Connections
• Support Activities at Floating Facilities during Riser

Installations

• Pipe Lays over Cable Route
• Seismic Surveys through Lease Blocks

Network Effectiveness

• Ability to monitor platform motions

and stability through storm events

• Preliminary assessment of systems

prior to sending crews offshore

• Undamaged, full-time

communications in place to allow earlier return of facility personnel

• With earlier deployment of personnel,
• il production re-started with

substantially less downtime
