MarineMammalMitigationSystems

Seiche Measurements Limited (Seiche)

designs and manufactures underwater

sound measurement and marine mammal

monitoring equipment for the oil and gas

and renewables sectors. Seiche systems

enable its customers to comply with

environmental regulations that protect

marine mammals from the effect of sound

in the water. Seiche equipment is deployed

worldwide.

Seiche is the market leader in

the provision of passive acoustic

monitoring (PAM) for the Oil

and Gas and Renewables sector,

supplying equipment to oil

companies, seismic exploration

contractors, service companies

and research institutes.

Seiche currently supplies a

wide range of products for

mitigation and measurement of noise in off shore applications.

The company’s success is based on the ability to supply and

install kit that is fit for purpose at the right time and in the right

place. The quality of equipment and service enables compliance

with environmental regulations and minimizes the noise impact

on marine mammals. We back up our technical capability with

unparalleled service.

Seiche has facilities in the UK and in Houston, USA. We are

also able to provide in-location support using our partners in

destinations around the world.

Applications

Exploration

Seismic survey

PAM is becoming standard practice for

marine mammal mitigation on seismic

surveys vessels operating world-wide.

The Seiche towed PAM system is the

most trusted and deployed system for

marine mammal mitigation.

VSP

The Seiche VSP system is light enough

to be mobilised by helicopter and

quick to set up and deploy, ideal for

short seismic surveys which require a

portable and effective system.

Construction

Pre-Construction site survey

Often undertaken as a preliminary

survey for potential off-shore

construction sites. Using dedicated

research and survey vessels and a

team to monitor for birds and marine

mammals the Seiche towed PAM

system provides a ready solution.

Construction Phase

Pile driving operations require

monitoring and mitigation for marine

mammals. Typically this could consist

of a towed system, vertically deployed

hydrophone system or radio linked

single or multiple buoy networks.

Post Construction Phase

Bespoke solutions for long term

monitoring of underwater ambient

noise can be provided, depending

on the type of construction and

environment to be monitored.

Explosive Decommissioning and

ordnance clearance

The explosive can produce a huge

amount of energy in the water

requiring monitoring and mitigation

for marine mammals during these

operations. Buoyed or vertical array

deployments can be used.

Research

Environmental Baseline surveys

Seiche towed systems are used to

complement visual surveys for marine

mammal abundance. The systems

can target individual species or use a

wide band to encompass all marine

mammals.

Species Abundance surveys

Pure research surveys for individual

species can use bespoke Seiche PAM

systems utilising either a towed array

or remote radio linked buoy to target

individual species and their peak

emitted frequencies.

Applications are for the mitigation of noise during seismic exploration, construction and research studies

Towed Passive Acoustic Monitoring System

The most extensively used Passive Acoustic Monitoring system worldwide.

Arrays can be towed directly from the exploration vessel or from the seismic gun

strings. The system uses standard ethernet cables on-board the vessel to allow

monitoring at a convenient location on the vessel or remotely via a satellite link.

All Seiche PAM systems utilize PAMGUARD monitoring software.

Multi Vessel Mitigation Systems

Developed for use with multiple vessel surveys with the prime aim of reducing

the number of personnel required to run passive acoustic monitoring systems on

a fleet of vessels operating in close proximity.A telemetry link transmits individual

ships data to a central control and operator. One operator can monitor all the

vessels in the fleet with only minimal support.

VSP Hydrophone System

Light enough to be mobilised by helicopter, and quick to set up, the VSP

Hydrophone is a general underwater acoustic system for use around static

sources, such as rigs or monitoring the underwater environment. The system

gives a visual display of underwater noise using spectrogram, click, moan and

whistle detectors and gives an audio output to headphones.

Remote Buoy Acoustic Monitoring

The system consists of buoy flotation unit, electronics, batteries, hydrophones

and a transmitter and receiving unit. The buoy can operate as a single monitoring

unit or as multiple units deployed around a sound source. This system enables

wide band acoustic signals to be amplified and transmitted to a receiving station

in real time where the acoustic signals are processed.

Advanced Optical Transmission System

A state of the art system for underwater acoustics research. Utilizing the latest

high speed digital transmission techniques this system is a low noise wide

bandwidth research tool with inbuilt depth and temperature sensors.

Camera Monitoring Technology

HD video based visual monitoring system with Real-time Automated Distance

Estimation at Sea (RADES) and Thermal detection imaging.
