Well Intervention

Secc’s Subsea EQD deliver critical operational and safety advantages to companies conducting well intervention projects, particularly when using Riserless Light Well Intervention (RLWI) vessels or vessels of opportunity. These technologies are designed to streamline intervention processes, enhance operational efficiency, and provide robust protection for subsea hardware, personnel, and the environment.

High-Performance Fluid Interventions

For operators performing fluid (hydraulic) interventions to remediate flow assurance issues, enhance production through stimulation programs, control or kill a well, Secc’s couplings enable efficient, high-rate fluid transfer to and from the well. Whether the goal is to improve flow rates, remove blockages, or stimulate the reservoir, these couplings ensure reliable performance even under the most demanding conditions. Their full-bore, pressure-balanced design minimizes flow restrictions, enabling seamless operations across a range of intervention scenarios.

Safety-First Design

Secc’s Hot Make Hot Break and Mid Line Weak Link Connectors feature a patented full-bore, zero-loss, pressure-balanced mechanism that ensures safety and reliability. These couplings incorporate a mechanically-operated dry-disconnect system that autonomously seals both bores upon disconnection. This feature is vital in scenarios such as uncontrolled vessel drift-offs, which may occur due to rough sea conditions or failures in the vessel’s Dynamic Positioning (DP) system. Acting as a weak link, disconnection of the coupling protects personnel, topsides and subsea equipment.  Sealing the bores on both sides of the disconnection prevents environmental contamination.

Key Features and Benefits

  • Quick Connect and Disconnect: Allows operators to rapidly initiate or terminate intervention operations, reducing downtime and improving operational efficiency.
  • Full-Bore: Supports high-rate fluid transfer even in deep-water environments, maintaining performance without compromising system integrity.
  • Pressure-Balanced: Removes separation loads on the coupling interface by simply matching the piston effect on the coupling.
  • Emergency Dry Disconnect: Enhances safety by sealing the bores automatically, protecting personnel, subsea hardware, and the environment during unexpected events.
  • 360° Drift-Off Protection: Provides comprehensive safeguards against vessel drift-offs, ensuring uninterrupted operations in challenging sea conditions.
  • Versatile Deployment Options:
    • Subsea-mounted configurations for permanent placement on subsea production equipment such as manifolds, trees, PLEMS and PLETS.
    • Mid-line or vessel-positioned solutions adaptable to a variety of operational needs.
  • Compatibility with Intervention Tools: Works seamlessly with coil tubing and flexible interfaces, offering adaptability across intervention setups.
  • Diver or Diver-less Operation: Enables flexible deployment and operation depending on project requirements.

Applications

Secc’s coupling solutions are ideally suited for:

  • Stimulation Programs: Enhancing well productivity by injecting acids, chemicals, or hydraulic fluids.
  • Scale and Debris Removal: Supporting cleaning operations to restore flow efficiency.
  • Remediation of a variety of flow assurance issues: Supporting the removal of hydrates, wax, asphaltenes and other materials that can impair production.
  • Hydraulic Interventions: Addressing wellbore challenges to improve recovery rates.
  • Permanent Subsea Installations: Facilitating long-term intervention readiness when installed on subsea production equipment such as manifolds and subsea trees.
