Underwater sound – Perspective from the oil and gas offshore industry in Europe

March 2021

This policy brief  gives an overview of underwater sound and how it is managed.

Background

Underwater sound comes from various natural and man-made sources. Potential impacts, if any, of a specific sound depends on its characteristics, the marine species receiving the sound and other characteristics of the marine environment.

A range of mitigation measures are typically implemented during offshore oil and gas industry activities. These are often combined with data collection methods that are carefully designed and implemented to address potential site-specific safety and environmental impacts identified during project planning.

IOGP develops international recommended practices and good practice guidelines to help inform assessment processes and provide recommendations for monitoring and mitigation activities. IOGP and its members also actively engage in research programmes to further advance scientific understanding of potential impacts and improve mitigation and monitoring methods.

What can Europe do?

  • Work with Regional Sea Conventions to ensure common definitions and assessment methodology, while taking into account international frameworks and regional ecological specificities
  • Adopt flexible and provisional threshold values, that could be revised and adjusted as science progresses and new data is available
  • Support research focused on identifying and quantifying impacts on marine mammal populations – not just individuals – in EU, national, and regional projects
