Regulatory requirements for effective noise mitigation have increased, particularly for the protection of whales and dolphins. It is now standard practice across several industry sectors to use passive acoustic monitoring (PAM) to detect vocalising marine mammals, in real-time, to ensure none are within close proximity of an active sound source.

shippingOur Approach

Seiche is the leading supplier of PAM equipment worldwide. We provide a range of solutions, from simple over-the-side hydrophones to the most highly advanced low-noise digital arrays.

We have been at the forefront of the development of PAM technology since the 1990s, and have successfully completed a wide range of projects around the world, supplying to the oil and gas, renewables, defence and civil engineering industries.

Worldwide Logistics

Our dedicated logistics department ensures the right equipment is in the right place at the right time. Our bases in the UK, USA, Scandinavia, South Africa and Australia have extensive experience in transporting equipment all over the globe.

Seiche offshore technicians, who hold offshore certification, are skilled in the installation, maintenance and operation of all systems. Our personnel also have extensive experience of mitigation protocols, offshore PAM surveys and PAMGuard software.


Underwater Sound: Mitigation Techniques

Underwater Sound Mitigation Techniques Underwater noise has the potential to interfere with communication between whales. It can mask environmental sounds that animals use for navigation, foraging and the sounds of predators. High intensity underwater sound, including some sources of anthropogenic noise, can result in physical injury that can be either temporary or permanent. Indirectly, whales may be affected by underwater noise if it changes the distribution and availability of their prey.
