ISO 19030 - Measurement of changes in hull and propeller performance

(www.MaritimeCyprus.com) According to data published by the IMO, about one-tenth of the world fleet’s fuel consumption can be attributed to poor hull and propeller performance. This costs owners an estimated USD 30 billion in additional fuel costs per year and contributes to 0.3% of all man-made carbon emissions. Released in 2017, the ISO 19030 standard defines a set of performance indicators for hull and propeller maintenance, repair and retrofit activities to improve operational performance.

Hull and propeller performance refers to the relationship between the condition of a ship’s underwater hull and propeller and the power required to move the ship through water at a given speed. Measurement of changes in ship specific hull and propeller performance over time makes it possible to indicate the impact of hull and propeller maintenance, repair and retrofit activities on the overall energy efficiency of the ship in question.

The aim of the ISO 19030 series is to prescribe practical methods for measuring changes in ship specific hull and propeller performance and to define a set of relevant performance 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.

The standard offers a two tier methodological approach: ISO 19030-2, the default measurement method, with the most exacting requirements and greatest measurement accuracy; and ISO 19030-3, allowing for ‘alternative methods’ and included in order to increase the applicability of the standard.

The ISO 19030 series consists of three parts.

  1. ISO 19030-1 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.
  2. ISO 19030-2 defines the default method for measuring changes in hull and propeller performance and for calculating the performance indicators. It also provides guidance on the expected accuracy of each performance indicator.
  3. 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 or higher overall accuracy but include elements which are not yet broadly used in commercial shipping.

The general principles outlined, and methods defined, in the ISO 19030 series are based on measurement equipment, information, procedures and methodologies which are generally available and internationally recognized.
