Environmental Monitoring - Renewables and Oil & Gas Projects


Kongsberg Environmental Monitoring Group provides technology and services to help improve efficiency and safety for offshore projects.

Underwater Noise Monitoring

The introduction of new legislation in the form of the EU Maritime Strategy Framework Directive (MSFD) means that baseline and impulsive noise will have to be monitored often throughout the life cycle of an offshore construction project. Examples are construction noise from piling during installation of wind farms or noise from operation of airgun arrays during seismic operations. Such operations can generate noise at levels that may harm fish and marine mammals like whales and seals.

Kongsberg Maritime have developed a number of unique deployment methods for noise monitoring that can help reduce costs and increase safety. The systems use calibrated hydrophones, traceable to international standards, together with signal conditioning amplifiers and digital data acquisition systems. Some systems even have unique intuitive user interfaces so that non acoustic personnel are able to understand the data being presented, in order to make operational decisions in ‘real-time’ during piling and decomissioning activities.

Integrated Environmental Monitoring

Integrated environmental monitoring

This system uses a subsea nodal network with integral sensors to provide real-time environmental data through wireless or cabled communication. The sensors themselves may be scanning sonars, acoustic Doppler current profilers; fluorimeters etc. The major benefit of the system is real time access to subsea environmental data forming the basis for early detection, and for fast response to potential environmental impact. We offer complete freedom in selecting sensors for every monitoring requirement. Data is delivered to the surface in the format you need, for logging, transfer or further analysis.

Autonomous underwater vehicles

SeaGlider AUV

Based upon our own industry leading hydroacoustic technology and sensor carriers, we have two main platforms for subsea environmental monitoring:

  1. Stationary Sensor Networks
    (see IEM)
  2. AUVs

We design and manufacture the HUGIN, MUNIN, REMUS and SEAGLIDER product lines of commercial off the shelf (COTS) autonomous underwater vehicles (AUV). These AUVs have different capabilities and thus different applications and roles. They are available with short delivery times.

  • HUGIN
    This AUV boasts operational experience from commercial and naval operations. HUGIN operations have taken place in all parts of the world, in shallow to deep water, in arctic and tropical waters.
  • MUNIN
    This AUV is designed to collect high resolution sonar data geo-referenced by a survey grade positioning system. It is an efficient compact vehicle design, providing for easier launch and recovery and the possibility of using smaller launch vessels
  • REMUS
    These AUVs have been a tremendous success with more than 250 vehicles delivered. REMUS vehicles are used in a wide number of applications including navies, hydrography and marine research
  • SEAGLIDER
    The Seaglider has revolutionized the way that oceanographic data is collected. Extremely long endurance allows collection of data at a fraction of the cost of traditional methods. Researchers, naval planners and commercial enterprises around the world are using these vehicles in a wide variety of applications. Seaglider can be equipped with a wide range of sensors and is a suitable tool for environmental monitoring.

Scour Monitoring

Scour monitoring

Kongsberg Maritime have developed a range of Dual Axis Scanning Sonar systems for 'Real Time' monitoring of scour on offshore wind farm monopiles and substations. The sonars are designed specifically for scour detection and sizing, with permanent immersion protection. Kongsberg can provide installation/maintenance, data collection/visualisation and reporting, so that it becomes a reliable decision support tool.
