What is ISO 9089 - Mooring positioning windlasses and winches about?
ISO 9089 specifies a classification, technical requirements, and test methods, as well as designation, marking and documentation requirements for mooring positioning windlasses and winches of mobile offshore floating units, including drill-ships, semi-submersible drilling rigs, production platforms, and offshore accommodation platforms.
Note1: ISO 9089 can be used as a reference for ship-shifting positioning winches of pipelaying, crane, and pile-driving vessels.
Note2: ISO 9089 is applicable to the design, manufacturing, and acceptance testing of mooring positioning windlasses and winches.
Who is ISO 9089 - Mooring positioning windlasses and winches for?
ISO 9089 on windlasses and winches is useful for:
- Windlasses and winches manufacturers
- Windlasses and winches design engineers
- Quality control personnel
Why should you use ISO 9089 - Mooring positioning windlasses and winches?
Windlass and winch and associated electric control system used for mooring positioning of mobile offshore floating units, including windlass and winch bodies (chain wheels/drums, drives, braking systems, anchor deployment (anchor dropping) speed limiters, etc.), chain or wire rope stoppers, anchor line guides and electric control system. Windlasses and winches help in the maneuvering of ships and in safely docking at ports and on the high seas.
ISO 9089 provides classification that will help you to classify the windlasses and winches according to functions and structural types.
ISO 9089 provides design, constructional requirements and test methods to be followed while manufacturing which will help in conforming to the regulatory standards manufacturing standardized windlasses and winches. ISO 9089 ensures that the windlasses and winches operate efficiently and prevents any hazards while operating.
What’s changed since the last update?
BS ISO 9089:2019 cancels and replaces BS ISO 9089:1985.
The main changes are as follows:
- Added no-load, nominal load, nominal speed, stalling/slipping load, anchor deployment (anchor dropping) speed limitation, anchor line length, speed and tension measurement, cable/wire rope stopper, ratchet mechanisms, etc. to the functional and operational requirements
- Refined all sub-items in design and construction, and quantified the requirements of all indicators and formula
- Provided an overview of various tests, and specified test types, methods and requirements
- Provided check items, sequence, qualification criteria for type inspection of mooring positioning windlass and winches
