Overview
ISO 7221:1984 establishes the principal technical requirements for shipborne barges, series 1, when they are loaded, unloaded and transported on board barge carriers. The standard addresses structural and operational considerations to ensure safe handling, stacking and stowage of barges within a carrier’s hold or on deck. It also highlights the need to account for inertia loadings arising from oscillatory and translatory motion of the carrier and any uneven distribution of load in the barge.
Keywords: shipborne barges, barge carriers, lifting posts, stacking, securing, weather-tight deck openings, ISO 4175.
Key Topics
Applications
This standard is primarily intended for:
- Shipbuilders and naval architects designing barge carriers and shipborne barges.
- Operators and cargo planners who load, stack and transport barges on carriers.
- Classification societies and regulatory bodies assessing compliance with structural and securing requirements.
Practical benefits include safer handling and reduced risk of damage to barges and cargo, improved load planning, and clearer requirements for lifting and securing hardware.
