Описание (английский):

The purpose of ISO 20154:2017 is to provide general guidelines on the design of ship vibration isolation based on the basic methodology of vibration isolation for shipboard machinery, for example, auxiliary engine, compressor, fan, pump, etc. A well-designed vibration isolation system can significantly reduce the vibration transmission from shipboard machinery to ship structures lowering the noise level onboard the ship or the underwater noise radiated from the ship.

Overview

ISO 20154:2017 - Ships and marine technology: Guidelines on vibration isolation design methods for shipboard auxiliary machinery - provides practical, high-level guidance for designing vibration isolation systems for shipboard machinery (for example, auxiliary engines, compressors, fans and pumps). The standard explains the basic methodology for reducing vibration transmission from machinery to ship structure, with the objective of lowering onboard noise and underwater radiated noise.

Key Topics

Scope and intent: Guidance for ship vibration isolation design to reduce structural vibration and onboard/underwater noise and to support early planning of space and weight for isolators during ship design.

Design principles: Emphasis on achieving low natural frequency relative to excitation frequency (recommended f / f_n > 2) to obtain effective isolation, while avoiding resonance and ensuring machinery stability.

Single-stage isolation: Procedure including spectral analysis of disturbance (referencing ISO 20283-3), calculation of natural frequency (function of stiffness and mass), selection and layout of isolators, and foundation design.

Double-stage isolation: Guidance on intermediate mass/stiffness design, selection of upper and lower isolators, and arrangement to achieve higher attenuation (typically greater reduction than single-stage).

Performance expectations: Typical attenuation ranges - single-stage can reduce transmission by more than ~15 dB; double-stage systems can reach ~25–30 dB depending on intermediate mass.

Practical considerations: Machinery vibration severity limits (refer to ISO 10816), environmental adaptability, stability under ship motions (rolling, pitching, yawing), use of displacement limiters, ease of installation and maintenance.

Testing and verification: Use of spectral measurements and coast-down tests / resonant frequency determination (Annex A) to validate design.

Applications

ISO 20154:2017 is intended for:

Ship designers integrating vibration isolation early in vessel design

Marine and naval architects specifying machinery foundations and isolators

Vibration consultants and acousticians performing isolation analyses

Shipyards and equipment suppliers selecting and installing isolators

Classification societies and regulators assessing vibration/noise mitigation measures

Practical uses include reducing crew noise exposure, minimizing structural vibration fatigue, and lowering underwater radiated noise to protect marine life and meet regulatory expectations.
