Metas has together with IMR been rewarded funding from The Research Council of Norway to be a part of the exciting FoU project Autonomous Robotic sea-floor Infrastructure for bentho-pelagic Monitoring. (ARIM). This is part of the MarTERA Horizon 2020 initiative. If you want to read more about this, just click here.
In this project, one of our partners is Kraken Robotics. They are developing the autonomic module. If you want more info, you can read the press realise from Kraken here.
Metas AS has together with Statoil successfully installed and commissioned the new upgrades of LoVe Ocean Observatory. The upgrade consist of two satellite units and one X-frame containing several measurement devices and cameras. All data collected are transmitted through the subsea cable from the units to a land base where the data is stored and transmitted to Statoil web site.
Metas will be exhibiting our new innovative launch and retrieval tool and the subsea crawler at the UTC (Underwater Technology Conference ) exhibition, which takes place on the June 21th and 22nd (Wednesday and Thursday), 2017.
METAS has received funding from Innovasjon Norge to support our work and development towards the fish farming industry. This support will accelerate our commercialization plans for METAS stereo camera that will be used to measure salmon size in the fish farming industry.
The Crawler can be equipped as a mobile ocean observatory, take samples from the sediment and operate over a wide area. It can be accessed via a standard Internet connection and be operated remotely via the web as the world`s first Internet operated deep-sea crawler. The Crawler has been in operation since 2010 in and around the world largest cabled ocean observatory in Canada (NEPTUNE Observatory).
We see this agreement as a unique opportunity to move into mobile environmental monitoring for several industries including scientists gathering vital information about oceanology. Metas will be responsible for Sales, Services and Operation in Norway. See link to iSeaMC web site (http://www.iseamc.com/).

The main features of X-net® system is summarized by the following points: Standardized
designed as a modular system for easy and rapid deployment and retrievals
All infrastructures have the same standardized design (no special design needed)
An X-frame could easily be changed from containing sensors to a garage / docking station for a Crawler / AUV or both and still fit into the existing Node without any design change
Could be used for both cabled and autonomous ocean observatories
The sensor frame (X-Frame) contains all sensors as a package for one particular Node, minimizing the amount of wet mate-able connectors and as such reducing the overall cost and complexity
The X-Frame with sensor package can be retrieved and redeployed in the most time efficient way saving expensive vessel operation time
The design of X-node and X-frame reduce need of expensive ROV operation during maintenance of sensors. This means that smaller less costly vessels could be used, reducing cost for vessel time and hire of expensive ROV`s
Uptime of Ocean observatory
A spare sensor platform with all sensors installed could be used to replace existing platforms during maintenance. The platform to be maintained are retrieved, and the replace platform immediately deployed. This is reducing cost for vessel time, and also contribute to minimum gap in time series of data.
The X-Node and X-frame is designed for 25 years operation time in accordance to subsea requirements for the oil and gas industry.
METAS has filed a patent application that includes this innovative solution. The image depicts delivery of X-Frame® on top of X-Node® located on the sea floor. LRT_operations
Metas has as of November 7th 2016 received a contract from Statoil. The contract is for an upgrade of the Love Ocean observatory, including installation of two satellites on the observatory. Satellite on LoVe. (Image Courtesy of Statoil/DeepOcean)
There is an increased need to detect, identify, and monitor natural and manmade seabed gas leaks. Fisheries echosounders are well suited to monitor large volumes of water and acoustic frequency response [normalized acoustic backscatter, when a measure at one selected frequency is used as a denominator, r(f)] is commonly used to identify echoes from fish and zooplankton species. Information on gas plume r(f) would be valuable for automatic detection of subsea leaks and for separating bubble plumes from natural targets such as swimbladder-bearing fish. Controlled leaks were produced with a specially designed instrument frame suspended in mid-water in a sheltered fjord. The frame was equipped with echosounders, stereo-camera, and gas-release nozzles. The r(f) of laterally observedmethane,carbon dioxide, and air plumes (0.040–29 l/min) were measured at 70, 120, 200, and 333 kHz, with bubble sizes determined optically. The observed bubble size range (1–25 mm) was comparable to that reported in the literature for natural cold seeps of methane. A negative r(f) with increasing frequency was observed, namely, r(f) of about 0.7, 0.6, and 0.5 at 120, 200, and 333 kHz when normalized to 70 kHz.Measured plume r(f) is also compared to resolved, single bubble target strength-based, and modeled r(f).
