Overview

ISO 1964:1987 - "Shipbuilding - Indication of details on the general arrangement plans of ships" is an ISO standard produced by ISO/TC 8 (Shipbuilding and Marine Structures). It defines a consistent set of graphical symbols for showing equipment and details on a ship’s general arrangement (GA) plans. Symbols are drawn approximately to 1:100 scale (and scaled proportionally for 1:50 or 1:200 plans). The standard helps make GA drawings clear, interoperable and suitable for regulatory review.

Key topics

• Scope of symbols: standardized symbols are provided for nine main categories:
  • 1 Bulkheads (walls) and bulkhead openings
  • 2 Accommodation furniture (berths, seating, tables, storage)
  • 3 Sanitary equipment (basins, lavatories, showers, WC types)
  • 4 Galley and laundry (ranges, refrigerators, washers, dryers)
  • 5 Workshops (benches, lathes, drill machines)
  • 6 Navigation and bridge equipment
  • 7 Deck equipment
  • 8 Stairs, bulwarks, ladders
  • 9 Hatches and covers
• Basic elements: core/basic symbols are identified in clauses 1.1, 2.1 and 3.1 and may be combined with other symbols; examples of combinations are provided throughout the standard.
• Scaling and representation: symbols are drawn at ~1:100 and may be enlarged/reduced proportionally for other plan scales; symbols can be drawn to reflect actual equipment size and proportions.
• Special equipment: items not listed may be represented by a representative-shaped symbol and accompanied by a reference number linking to an explanatory legend.
• Fire-related notation: where applicable, lettered symbols may be followed by numbers indicating limitation of temperature rise periods; the standard references SOLAS Regulation 35 (1974, amended) and IMO Resolution A.517(XIII) 1983 for context.

Applications

ISO 1964:1987 is used to:

• Produce clear, consistent general arrangement (GA) plans used in ship design and documentation.
• Communicate equipment layout in shipyards, design offices and with classification societies.
• Support regulatory and safety reviews (e.g., fire-zone and escape-route planning) by standardizing how bulkheads, doors, windows and sanitary fittings are shown.
• Create drawing legends and index entries for special or bespoke machinery using numbered symbols.

Typical users:

• Naval architects, ship designers and draughtsmen
• Shipbuilding yards and marine engineering offices
• Classification societies, flag administrations and surveyors
• Regulatory authorities reviewing GA plans for compliance

Related standards

• SOLAS (International Convention for the Safety of Life at Sea) - Regulation 35 and related amendments
• IMO Resolution A.517(XIII) (1983) - referenced for fire and temperature-rise considerations
