Full title and description

Ships and marine technology — Measurement of changes in hull and propeller performance — Part 2: Default method. Defines a repeatable/default method for measuring changes in hull and propeller performance and for calculating a basic set of performance indicators for comparing a ship to itself over time.

Abstract

ISO 19030-2:2016 specifies primary and secondary measurement parameters, data handling and calculation procedures needed to determine changes in hull and propeller performance (performance values and performance indicators) and gives guidance on expected accuracy. It is intended for commercial displacement ships driven by conventional fixed‑pitch propellers where the objective is comparison of the same ship over different periods.

Scope

Specifies the default measurement approach and calculation methods to: (1) measure and record relevant primary parameters (ship speed through water, delivered/shaft power or approximations where shaft torque is not available), (2) collect secondary and environmental data (wind, waves, draught, trim, operational profile), (3) apply filtering, normalization and corrections, and (4) compute performance values and aggregate them into performance indicators to detect changes in hull and propeller performance of the same ship over time. The standard limits its default method to displacement commercial ships with conventional fixed‑pitch propellers (extensions for other configurations may be included in later revisions).

Key topics and requirements

• Definition of primary measurement parameters: ship speed through water, delivered/shaft or brake power estimation, shaft torque/revolutions when available.
• Requirements for secondary/environmental measurements: wind, waves, draught, trim and operational profile for normalization and correction.
• Data acquisition, storage, filtering, validation and outlier detection procedures to ensure repeatability.
• Calculation procedures for performance values (PVs) and aggregation into performance indicators (PIs) with defined reference and evaluation periods.
• Guidance on estimating and reporting uncertainty and expected accuracy of each performance indicator.
• Informative annexes providing practical protocols, power–speed–draught–trim databases, correction methods and worked examples.

Typical use and users

Ship operators, technical superintendents, ship performance analysts, naval architects, shipyards and third‑party performance monitoring providers use ISO 19030-2 to quantify changes in hull and propeller condition after maintenance, fouling removal, repairs or retrofits, and to support fuel‑efficiency and condition‑monitoring programmes.

Related standards

ISO 19030 is a multipart series. Part 1 (ISO 19030-1:2016) covers general principles and defines the set of performance indicators; Part 3 (ISO 19030-3:2016) describes alternative methods (options that trade applicability and accuracy). These related parts are intended to be used together when developing a ship performance measurement programme.

FAQ

Q: What is this standard?

A: ISO 19030-2:2016 is the part of the ISO 19030 series that specifies the default, repeatable method for measuring changes in a ship’s hull and propeller performance and for calculating basic performance indicators to compare a ship to itself over time.

Q: What does it cover?

A: It covers required measurement parameters, environmental data collection, data handling (filtering/validation), calculation of performance values and indicators, and guidance on estimating PI accuracy; informative annexes provide practical procedures and examples.

Q: Who typically uses it?

A: Ship operators, performance analysts, naval architects, yards and third‑party monitoring/service providers who need standardized, repeatable methods to detect performance changes related to hull and propeller condition.

Q: Is it current or superseded?

A: ISO 19030-2:2016 is the published edition (edition 1, 2016) and was confirmed during ISO’s periodic review cycle; users should check with their national body or ISO catalogue for any amendments or later revisions if absolute current status is required.

Q: Is it part of a series?

A: Yes — it is Part 2 of the ISO 19030 multipart standard; Part 1 addresses general principles and performance indicators, and Part 3 describes alternative methods. The parts are intended to be used together for comprehensive performance measurement practice.

Q: What are the key keywords?

A: Hull performance, propeller performance, performance indicators (PIs), speed through water, shaft/delivered power, normalization, uncertainty, ISO 19030.
