What is ISO 11592-1 - Manoeuvring speed about?
ISO 11592 is an international standard on small craft that discusses the criteria for measuring maximum propulsion power. ISO 11592-1 is the first part of a series of documents on small craft. ISO 11592-1 specifies the requirements for the determination of the maximum propulsion power rating and manoeuvring speed for engine-driven small craft with a length of hull (LH) of less than 8 m (Lh according to ISO 8666).
ISO 11592-1 does not apply to the following:
- Personal watercraft as defined by ISO 13590
- Canoes and kayaks
- Inflatable boats, as defined by ISO 6185-1, ISO 6185-2, ISO 6185-3, and ISO 6185-4, except that ISO 6185-3 requires rigid inflatable boats (RIBS) capable of a maximum speed of 30 kn or more to be tested in accordance to ISO 11592-1
- Racing boats: craft designed and constructed solely for competitive racing
NOTE: ISO 11592-1 does not specify craft constructional strength requirements related to maximum rated power and does not guarantee security from instability under all conditions of seaway, wind, wakes and waves.
Who is ISO 11592-1 - Manoeuvring speed for?
ISO 11592-1 on the determination of maximum propulsion power is relevant to:
- Marine engineer
- Manufacture of small crafts
Why should you use ISO 11592-1- Manoeuvring speed?
Manoeuvring is an operation during which a vessel enters or exits the coastal waters of a country, crosses several ships on the way, and proceeds towards or departs from a berth or jetty of a port.
ISO 11592-1 provide guidance on determination and marking of the maximum propulsion power rating, outboard-powered craft, other types of craft, power capacity label and owner’s manual, test craft preparation, test conditions and determination of maximum speed, manoeuvring test procedure and criteria.
As a user of ISO 11592-1, you can be ensured of maximum propulsion power rating and manoeuvring speed for engine-driven small craft with a length of hull of less than 8 m. ISO 11592-1 supplies tried and tested methods that will help you efficiently calculate maximum propulsion power rating and manoeuvring speed which helps you in managing the speed of the engine.
