Overview
ISO 6765:1985 is an international standard published by the International Organization for Standardization (ISO) that specifies the main dimensions and principal constructional elements of shipborne barges, series 3. These barges are designed to be embarked aboard barge-carrying ships, utilizing lifting or floating dock systems for loading and unloading. The standard ensures consistency in dimensions, aiding interchangeability and safe stowage during maritime transport.
Developed by ISO Technical Committee ISO/TC 8 on Shipbuilding and Maritime Structures, ISO 6765 facilitates uniformity in the design and handling of shipborne barges, thereby supporting efficient logistics in maritime and inland waterborne transport sectors.
Key Topics
-
Scope and Definition
The standard defines series 3 shipborne barges as barges embarkable on specialized ships via elevators or floating dock systems. It sets forth exact main dimensions and elements crucial for construction and operation.
-
Main Dimensions
ISO 6765 precisely specifies dimensions such as:
- Length (L)
- Width/Beam (B)
- Height (H)
- Draft (T)
- Freeboard/Depth (N)
- Displacement (D)
These dimensions ensure barges conform to uniform size specifications, enabling them to fit securely onboard barge carriers.
-
Positioning and Securing Components
The standard mandates the inclusion of:
- Positioning angle irons at the barge bottom for accurate placement
- Vertical locking devices on the upper deck of the barge carrier for secure stowage
- Support points on the carrier’s false deck for fastening hydraulic jacks or securing devices
These features promote safe handling and reduce movement during transport.
-
Tolerance Specifications
ISO 6765 defines dimensional tolerances to maintain interchangeability and compatibility with shipborne lifting and securing equipment. This ensures barges from different manufacturers can be stowed and handled uniformly.
Applications
ISO 6765:1985 is essential for:
-
Shipbuilders and Barge Manufacturers
Ensures shipborne barges meet international dimensional standards for compatibility with barge carriers.
-
Maritime Transport Operators
Facilitates safe and efficient transport of barges aboard ships, reducing risks during loading/unloading and transit.
-
Port and Terminal Facilities
Guides infrastructure design for handling barge embarkation systems like elevators and floating docks.
-
Logistics and Fleet Management
Assists in fleet standardization and maintenance practices for barges and barge carriers, optimizing operational workflows.
The standard’s detailed dimensional requirements help maintain safety, reliability, and interoperability across the maritime industry, especially in inland and coastal transportation where barges play a vital role.
Related Standards
Stakeholders using ISO 6765 may also reference the following standards for comprehensive guidance:
- ISO 3874 – Ships and marine technology – Container securing on ships
- ISO 668 – Series 1 freight containers – Classification, dimensions, and ratings
- IMO International Maritime Solid Bulk Cargoes (IMSBC) Code – for classification of bulk cargoes carried on barges
- National shipbuilding and barge construction standards, which may provide complementary tolerances and material specifications
By aligning with ISO 6765 and related standards, maritime organizations can enhance safety and efficiency in the deployment and carriage of shipborne barges worldwide.
