What it is Filled

The system of frames (ribs) and associated members that shape and strengthen a ship's hull, arranged transversely, longitudinally or in combination; in wooden ships it includes floor timbers (wrangs) across the keel.

Why it exists Filled

Let an agent describe a ship's framing system, its members and spacing, its role in structural strength and inspection, and point to classification rules.

Distinguishing features Filled

  • Transverse framing uses closely spaced ribs; longitudinal framing uses stiffeners running fore and aft with widely spaced web frames.
  • Frames are internal structure, not the hull plating.
  • Frame numbers give locations on board.

What robots and AI may and may not do Filled

Must not

  • declare a hull fit for service without a survey
  • advise structural modifications without class approval

Only with a human decision

  • structural repairs and survey decisions

May

  • describe framing systems and members
  • point to rules and survey records

Moral aspects Filled

  • safety of crews and the marine environment

Who is affected

  • crews and passengers
  • shipowners

Owners Filled

Steward

the shipowner, under the oversight of the classification society and flag state

Master systems

  • class survey records
  • ship structural drawings

Links to other meta-models Filled

parent

  • Q811430 - registry parent class

related

  • ship hull - hull structure
  • hull plating - the outer shell
  • classification society rules - structural requirements

contains

  • floor (wrang) - the floor timber across the keel in wooden ships

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.ship-framing
  • Wikidata: Q13586691 (https://www.wikidata.org/wiki/Q13586691)
  • frame number: ship-specific position reference along the hull

Direct properties required Filled

  • transverse frame spacing: 0.5-1 m - ordinary transverse frames of steel merchant ships; longitudinals and web frames are spaced differently

Recognition required Filled

  • Regularly spaced frames along the inside of the hull
  • Frame numbers marked on structure
  • Floors across the bottom between keel and bilge
  • Rows of ribs or stiffeners inside the hull, with floors across the bottom and stringers or longitudinals along the length.

Capabilities and actions required Filled

  • identify the framing system of a hull
  • name framing members
  • use frame numbers as location references
  • point to classification rules and survey practice

Hazards and failure modes required Filled

  • Corrosion and fatigue cracking of frames
  • Buckling under loads
  • Structural failure leading to loss of the ship

Standards and interfaces required Filled

  • IACS Common Structural Rules for bulk carriers and oil tankers, where applicable by type, size and date
  • SOLAS Chapter II-1 construction requirements (IMO), where applicable

Context of use required Filled

  • Giving the hull its shape and the strength to resist water pressure, cargo loads and waves.
  • transverse framing
  • longitudinal framing
  • combined framing
  • wooden ship framing with floors and futtocks
  • web frames

Sources Filled

  1. Q13586691 - identity of the registry item, labels and sitelinks
  2. Principles of Naval Engineering - hull framing
  3. Common Structural Rules - structural rules
  4. Ship Design and Stability - SOLAS construction

Open questions

  • Should wooden-ship framing (floors, futtocks) be a separate entry?
