New guidance on deep water acoustic positioning

Posted on 16.12.2009 - 13:00 UTC in SURVEY NEWS by Rons_ROV_Links

New guidance on deep water acoustic positioningIMCA has published a new authoritative guide for users and potential users of acoustics for underwater positioning. The document particularly addresses deep water activities, although many of the techniques and applications are also applicable to shallow water. The document is intended to inform and bring a general understanding of deep water acoustics to the reader, while more detailed technical appendices are provided for in depth study.


This guidance document was developed to provide an authoritative guide for users and potential users of acoustics for underwater positioning (especially in relation to deep water activities). It covers the basics of acoustics and signalling, the equipment required, methods of acoustic positioning and their limitations, and the operation and performance of acoustic positioning systems.

The focus is on the use of acoustic positioning systems and techniques for deep water operations. However, it should be recognised that many of the techniques and applications are also applicable to shallow water and in these circumstances the user should consider the pros and cons of the approaches available for use.

This document does not attempt to compare and evaluate different manufacturers, their products, services or the specific performance of systems - nor does it set out to provide a prescriptive set of procedures. Rather, this document is designed to provide consideration and guidance for the use and operation of any of the main types of systems.

In considering deep water acoustics, this document focuses on the use and application of acoustics for positioning tasks and how a user should consider the various factors influencing the selection of operational techniques for different applications. The main part of the document is intended to inform and bring a general understanding of deep water acoustics to the reader. More detailed technical appendices are provided for in depth study.

These guidelines are also available with the reference IMCA S 013.
