What it is Filled

A thick, strong rope or line, traditionally of twisted fibre and now often of steel wire, used for mooring, anchoring, hauling and suspension; also a nautical length.

Why it exists Filled

Let an agent handle cables as heavy ropes by construction, strength, inspection and safe use, and separate them from electrical cables.

Distinguishing features Filled

  • Heavy rope or wire rope
  • Rated by breaking load
  • Needs regular inspection
  • Electrical and data cables are separate entries

What robots and AI may and may not do Filled

Must not

  • Load a cable beyond its rated working load or use one that has failed inspection.
  • Let people stand in the snap-back zone of a cable under tension.
  • Cast off, cut or release a mooring cable without the master's or operator's order.
  • Leave a slack cable where it can trip people or foul a propeller.

Only with a human decision

  • Releasing or cutting a cable that holds a vessel or a suspended load.
  • Returning a damaged cable to service.

May

  • Inspect a mooring or hauling cable and report wear, broken strands or corrosion to its owner.
  • Handle, coil and secure a cable on a vessel or site where the agent is authorized to work.

Moral aspects Filled

  • A parting cable under load can kill or maim people nearby.
  • Neglected moorings put vessels, crews and harbours at risk.

Who is affected

  • Crew and dock workers
  • People near hauling or lifting operations
  • Owners of moored vessels

Owners Filled

Steward

The owner or master of the vessel, or the operator of the site where it is used.

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.cable
  • Wikidata: Q646462 (https://www.wikidata.org/wiki/Q646462)

Direct properties not applicable Not applicable

  • diameter: 10-100 mm - heavy ropes and wire ropes
  • cable length (nautical): about 185 m - one tenth of a nautical mile

Plane INF: no invented physical properties.

Recognition optional Filled

  • Thick twisted or braided construction
  • Wire rope designations such as 6x36
  • Electrical cables have conductors and insulation
  • A heavy twisted or braided line of fibre or steel strands.

Capabilities and actions required Filled

  • rig and moor with it
  • check its rated load
  • inspect for wear
  • splice or terminate it

Hazards and failure modes required Filled

  • Snap-back when a loaded line breaks
  • Corrosion and broken wires
  • Overloading beyond rated capacity

Standards and interfaces required Filled

  • EN 12385 steel wire ropes
  • ISO 4309 cranes - wire rope inspection and discard
  • Lifting equipment regulations such as LOLER

Context of use required Filled

  • Mooring and anchoring ships, lifting, hauling and supporting structures.
  • fibre hawsers
  • steel wire ropes
  • anchor cables and chain cables
  • suspension cables
  • cable-laid ropes

Sources Filled

  2. Wikipedia (fr): Bout (cordage) - general description of the item

Open questions

  • Should wire rope be a separate entry?
  • How should the electrical sense be split off?
  • How should inspection records be linked?
