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.

A subsea mining vehicle unloading rescue device uses a counterweight system to reduce weight and facilitate escape from sinking areas.

A composite gypsy uses a polymeric chain region and metal line grip to lower weight and manufacturing complexity.

A windlass assembly integrates the bow roller via a connection portion that secures mechanical alignment and fixes spacing between components.

A link coupler joins different sized chains using a dual chainwheel assembly with distinct wildcat profiles.

Surface-operated lift bags enable rapid anchor removal without divers, reducing costs while verifying holding capacity.

Integrated H-shaped shackle guides attachment element positioning on mooring pile frames, eliminating complex underwater operations.

Four-point mooring with buoy-connected hawsers lets tankers self-adjust orientation against wind and current shifts.

A tether connection apparatus featuring a pull-in winch and releasable connector mount for interconnecting mooring line ends.

Segmented wing plates increase antitorque bearing strength while open ends lower penetration resistance.

Helical guide grooves on the anchor shaft ensure precise orientation, preventing tilt and damage while maintaining a smooth hull profile.

A workboat anchor handling system uses a well structure to lift anchors near the center of gravity.

A chain tensioner uses a movable guide to shift the tensioning chain sideways for release.

A segmented anchor alignment guide rotates the shank up to 180 degrees, preventing fluke hull contact and ensuring smooth water flow.

Computational model simulates marine asset behavior using hydrodynamic principles to predict anchor position and mooring line tension distribution.

Internal cavity storage for a high aspect ratio signal buoy line prevents surface spinning, ensuring predictable breach locations.
