22、Hull and propeller performance refers to the relationship between the condition of a ships underwater hull and propeller and the power required to move the ship through water at a given speed. Measurements of changes in ship specific hull and propeller performance over time make it possible to indic

23、ate the impact of hull and propeller maintenance, repair and retrofit activities on the overall energy efficiency of the ship in question.The aim of this document is to prescribe practical methods for measuring changes in ship specific hull and propeller performance and to define a set of relevant p

24、erformance indicators for hull and propeller maintenance, repair and retrofit activities. The methods are not intended for comparing the performance of ships of different types and sizes (including sister ships) nor to be used in a regulatory framework.This document consists of three parts. ISO 1903

25、0-1 outlines general principles for how to measure changes in hull and propeller performance and defines a set of performance indicators for hull and propeller maintenance, repair and retrofit activities. ISO 19030-2 defines the default method for measuring changes in hull and propeller performance

26、and for calculating the performance indicators. It also provides guidance on the expected accuracy of each performance indicator. ISO 19030-3 outlines alternatives to the default method. Some will result in lower overall accuracy but increase applicability of the standard. Others may result in same

27、or higher overall accuracy but include elements which are not yet broadly used in commercial shipping.The general principles outlined, and methods defined, in this document are based on measurement equipment, information, procedures and methodologies which are generally available and internationally

28、 recognized.Clause 4 defines the primary and secondary parameters as well as external information needed. Clause 5 defines how measurement data are to be acquired, stored and prepared. Clause 6 defines how the performance indicators are to be calculated. Clause 7 provides guidance on the expected ac

29、curacy of each performance indicator.Annex A illustrates the process in terms of a flow chart.vi ISO 2016 All rights reservedBS ISO 19030-2:2016Ships and marine technology Measurement of changes in hull and propeller performance Part 2: Default method1 ScopeThis document defines the default method f

39、GeneralThis clause describes the primary and secondary parameters for measuring changes in hull and propeller performance.4.2 Primary parametersIn ISO 19030-1, ship speed through water, V, and delivered power, PD, are defined as the two primary measurement parameters for measuring changes in hull an

40、d propeller performance.Ship speed through water shall be measured directly, in knots, using a speed log with a minimum sensor accuracy of 1 %, at 11)of the speed of the ship, or 0,1 knots, at 1 (both as specified by the sensor manufacturer) whichever is greater.NOTE Since the overall accuracy assoc

41、iated with measurements of hull and propeller performance is highly sensitive to uncertainties in the measurement of speed, this requirement is intentionally stricter than current SOLAS requirements.Delivered power shall be approximated based on calculations of shaft power, Ps, from measurements of

42、shaft torque and shaft revolutions following Annex B or, if a torque meter with required signal quality is not available and the conditions defined in Annex C are fulfilled, shall be based on calculations of brake power, PB, from an engine-specific SFOC (specific fuel oil consumption) reference curv

43、e defined in Annex D, continuous measurements of fuel flow and temperature and bunker analysis data (calorific value, density and density change rate for the fuel being consumed).The approaches to calculating shaft power and brake power, as well as minimum required sensors and sensor accuracies for

44、each, are specified in Annex B and Annex C, respectively.The same approach to approximating delivered power shall be used throughout both the reference and evaluation periods.1) Confidence interval of 66 %.2 ISO 2016 All rights reservedBS ISO 19030-2:2016ISO 19030-2:2016(E)4.3 Secondary parametersFo
