Overview of Synthetic Tether Solutions
Cortland offers advanced synthetic tethers, including Selantic Tethers, which are highly rated for subsea applications. These tethers are used in mooring flexible risers, umbilicals, and Mid Water Arch (MWA) systems. They provide significant advantages over traditional steel wire and chain tethers.

Advantages of Synthetic Tethers
  • Weight Savings: Synthetic tethers are lighter, reducing buoyancy costs and simplifying installation.
  • Durability: They offer superior corrosion and fatigue resistance compared to steel.
  • ROV Friendly: Easy installation and component change-out using remotely operated vehicles (ROVs).
  • Longevity: Design lifetimes can reach up to 50 years.

Custom Hardware Components
Cortland develops hardware for easy installation and change-out, designed for ROV use, minimizing the need for divers. Key components include:
  • ROV Hooks, Delta Plates, and Anchor Bases: Facilitate full rotational freedom and tether change-out without extra pad eyes.
  • Selantic Delta Plate: Features include a double plate with pins, ROV positioning handle, corrosion protection anode, and a top handling shackle.
  • Twin Trunnion Plate: Connects to standard pad eyes, includes ROV handles, and offers free rotation towards MWA.
  • Selantic Anchor Connector: ROV-operated with free rotation towards the anchor, includes corrosion protection.
