Ships and marine technology. Determination of the shaft power of ship propulsion systems by measuring the shaft distorsion - Optical reflection methodWhat is ISO 20083 2 Shaft power of ship propulsion systems about? ISO 20083 2 is the second part of the ISO 20083 series of standards that specifies a procedure to determine the shaft power of engine ships, by measuring the shaft distortion using an optical reflection type device. ISO 20083 2 gives the principles of the measurement, the components of the device, and the calculation method. ISO 20083 2 also describes the factors for determining the

reference is made in several places to ISO standards accompanied by a short description of the method used

Beneath information authentication and integrity

The cableway installations designed for carrying people must draw up safety measures against fire protection to ensure the safety of passengers as well as staff

This is accomplished by defining message exchanges to allow these applications or systems access to public data and exchange information independent of how such information is represented internally
