Anchoring Arrangements TRIZ Cases
- Coaxial Mooring Tensioner for Low-Strain Line Alignment
A movable guide and coaxial layout let vessel winches tension mooring lines while reducing bending strain, friction, and wear.
- Symmetric Mooring-Anchor Layouts for Offshore Fatigue Control
Angled shared mooring anchors use compliance, redundancy, and secondary restraint to reduce installation cost and offshore fatigue risk.
- Fairlead Structure With Retractable Coupling Means
A fairlead structure uses retractable coupling means to connect a separate tensioning part, enabling modular assembly and simplified maintenance.
- Mooring Line Connecting System with Eccentric Pulling Mechanism
An eccentric pulling mechanism guides a pin into a hang-off structure, enabling diver-less connection and reducing wear on deepwater mooring lines.
- Subsea Mooring Chain Connector Tension Adjustment
A subsea mooring chain connector adjusts line length by dividing segments into tensioned and loose portions using a locking arrangement.
- Inline Tensioner for Polyester Mooring Line Stretch Removal
An inline tensioner system applies transverse force to remove visco-elastic stretch from polyester mooring lines during installation.
- Submerged Mooring Grid With Detachable Floating Platform
An artificial seafloor grid anchors vessels through a detachable floating platform, eliminating surface obstruction while maintaining structural stability.
- Offshore Fairlead Impulse Control Ratchet Mechanism
Impulse control with pawl mechanisms defines stable jaw positions, eliminating continuous power needs and reducing maintenance requirements.
- Mooring Line Watertight Sheath Corrosion Barrier
Watertight sheath encases mooring lines to prevent corrosion damage during transport and installation.
- V-Shaped Hawser System for TLP Tender Positioning
A V-shaped hawser system restricts vertical motion of lines near the tender bow to maintain consistent vessel positioning.
- Fairlead Guide Means for Anchoring Chain Tension Reduction
Curved guide surfaces and U-shaped pivot bearings reduce intermediate section tension in offshore anchoring chains.
- Floating Support Reel Docking Buoy for Extreme Weather
Relocating rolling bearings above the waterline reduces mechanical stress and enables easier maintenance in extreme weather conditions.
- Submerged Fairlead with Rotating Guide Means for Torsion Management
Rotating guide means distribute torsional loads across multiple links, reducing fatigue risks in permanent marine anchoring systems.
- Fairlead Counterweight Mechanism for Anchoring Chain Jamming
Counterweight inertia restores grip jaws to active locking positions, preventing jamming in submerged anchoring systems.
