Background

  • Offshore Oil & Gas Fields are Expensive to

Develop

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

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

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

Dynamic Riser Connection Installation

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

associated equipment

  • 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

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

  • Topside Coordination
  • Simultaneous Operations
  • Normal Loading & Transportation Techniques
  • Generate DRC lay procedures
  • Dry run DRC equipment overboarding

Coordination of topside activities required schedule integration early in the process to allow: Safety - Safety knowledge & procedures are already ingrained in the existing systems De-conflict installation through constant monitoring of in-field

  • Normal Loading & Transportation Techniques
  • No Alteration of Cable Load/Lay Equipment Required
  • Traditional Testing & Power Safety Procedures
  • Foundation of Standard Submarine Cable Product Handling
  • Dry run DRC equipment overboarding
  • Verify subsea equipment deployment procedures
  • Practice ROV wetmates, model ROV interventions

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 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
