What is ISO 13798 about?
ISO 13798 discusses standards for recessed bitts (steel plate type) used for mooring and towing purposes.
ISO 13798 specifies the types, nominal sizes, dimensions, and materials, as well as construction, manufacturing, and marking requirements, for steel plate type recessed bitts to meet normal towing requirements.
Who is ISO 13798 for?
ISO 13798 on recessed bitts (steel plate type) is applicable to:
- Marine industry
- Manufacturers of recessed bitts
- Shipbuilding and naval products manufacturers
- Vessel manufacturers
- Deck manufacturers
- Design engineers for recessed bitts
Why should you use ISO 13798?
The recessed bitt is a type of ship’s towing fitting installed on the shell side of the ship and is normally provided to easily attach the towing lines where the height of the mooring deck is too high and protect the rope from any damage on the hull. The guidelines provided in ISO 13798 can help you with the appropriate selection based on dimensions, type, size, and materials for recessed bitts, thus meeting normal mooring and towing requirements.
ISO 13798 provides guidelines about inspecting surfaces in contact with the ropes that should be free from surface roughness or irregularities to cause damage likely to the ropes by abrasion. ISO 13798 ensures the recessed bitts are coated externally with an anti-corrosion protective finish.
As a manufacturer, you can adopt ISO 13798 to ensure that recessed bitts for mooring and towing purposes adhere to the specification, imparting high operational efficiency and durability.
You can demonstrate the reliability of your products and build trust in their use throughout the marine supply chain by adhering to ISO 13798.
