Anchor Handling/Lashing TRIZ Cases

Multiple pulleys, a tortuous-path jammer, and a swivel make boat-to-anchor rope tightening easier while preventing slip and tangling.

Pressure-difference driving replaces slow mechanical vibration, installing annular anchors deeper and faster while keeping seabed positioning stable.

A sliding windlass mount lets pontoon boats remove the anchor and bow roller as one unit, preventing lift damage and easing storage.

A moonpool vessel combines tensioning, chain handling, and chain stoppers to proof load three anchors at once while adjusting line length safely.

An under-deck sliding tray moves heavy boat anchors horizontally, reducing lifting effort while keeping mud and water off the deck.

Rounded cutouts and sidewall inserts guide the anchor line away from sharp edges, reducing fraying and extending line life.

This case combines satellite navigation and sonar to detect anchor drift without relying on force or jerk thresholds.

Orthogonal rotational hinges and a guiding funnel distribute forces on mooring lines, reducing wear while enabling diver-less operations.

Spaced arms and cut-away slots on a buoy marker spool prevent line tangling in currents while a drive connector simplifies retrieval.

A dynamic anchoring system uses a winch to actively adjust anchor chain length and maintain constant tension force on floating bodies.

A computerized apparatus identifies suitable anchor locations within a geographical bounding box by applying multiple filters to exclude unsuitable regions.

Movable plates in the loop-securing structure prevent cable slippage while eliminating dangerous steel splicing operations.

Elastic mooring lines create restoring moments that dampen pendulum movements, allowing ships to anchor closer together without complex equipment.

A block and tackle assembly with a jammer creates a tortuous rope path to prevent slippage during boat anchoring.

A boost controller applies elevated voltage to a winch motor during anchor deployment.

A single-line mooring system uses a guided weight and block and tackle to define an inverted cone watch circle.

An anchor holding device secures the shank and fluke using an elastic band, notch, and indents.

A mooring pull-in system uses a crib to secure coupling parts on anchoring lines for deepwater vessels.

Relocating the winch assembly under the deck saves valuable space while shielding mechanical parts from corrosion and damage.

A turret system with a transportable windlass subsystem manages mooring lines through dedicated storage and channel sections.

Segmented clamshell panels wrap around sharp anchor shafts to eliminate collision hazards while maintaining lightweight portability through nested design.

Dynamic positioning connects a drilling unit to seabed anchors, eliminating anchor handling vessels and reducing energy consumption.
