Countries worked in: Kraken Robotics can operate globally although we will not deal with any locations on our excluded countries list.
Kraken Robotics is a marine technology company, specialising in the provision of robots as a service (RaaS), specifically super-high resolution acoustic surveys which can assist during all phases of an offshore wind development. Kraken's expertise also extends across a wide number of sectors including oil and gas, defense, civil engineering & construction.
Kraken Robotics Services (formerly PanGeo Subsea) has been changing the survey industry for over 15 years, by delivering innovative proprietary survey technology to de-risk projects, both pre-installation and across the operational life cycle of an asset.? Kraken can drive down CO2 emissions during offshore surveys by utilizing the latest survey technology, therefore, reducing vessel days in the field and reducing CO2 as well as saving time on the project schedule and costs.?

Case studies
Two wind farms are being developed within the Polish Baltic Sea. Both wind farms are expected to generate 720 MW of electricity from 29 wind turbine generators (WTG) when they are commissioned in 2026. Kraken Robotics were contracted to observe and interpret any potential unexploded ordnance (pUXO), all anomalies > 0.3m in diameter and any changes in sub-seabed stratigraphy. The acquired data would provide information to support future piling operations for the WTG installation and provide geohazard data along the inter array and export cable routes.

Kraken Robotics mobilised all equipment and personnel necessary to undertake the scope of the project. We deployed the Sub-Bottom Imager (SBI) on a remotely operated vehicle (ROV) to survey along the proposed export cable and inter-array cable routes. A continuous high resolution 3D data set, with a 6 m swath, penetrating 5m below the seabed was acquired to detect any geohazards on or below the seabed. Over the 15 day survey, Kraken Robotics detected 14,665 discrete geohazards along 456 km of proposed cable route. An Acoustic Corer (AC) survey was also carried out at the WTG locations for foundation mitigation, detecting any geohazards within the top 25m of the sub-seabed. The AC provides a 14m diameter cylinder of data with 0.1m resolution throughout the 3D dataset. Throughout the 28 day survey, 579 discrete geohazards were interpreted and multiple variations in stratigraphy were observed and cross correlated with borehole data.
A new offshore wind farm (OWF) was being developed within the central North Sea, off the coast of Angus, Scotland. The OWF was expected to generate 1,075?MW of energy once fully installed. Our client was installing wind turbine generator (WTG) jackets, which used suction-piles to emplace the jackets at the locations. During the emplacement of the suction piles at certain WTG locations, the piles encountered refusal at shallow depths. The refusal was understood to be related to an ultra-high strength clay layer, which occured approximately <1?m below seabed and had a maximum thickness of between 2 and 7?m according to client supplied geotechnical data. This clay layer was also suspected to contain a cobble layer, which may have been the main reason why pile refusal was occurring.

The objective of this project was to acquire Kraken's Sub-Bottom Imager (SBI) SAS data within a 157?m by 147?m box over each WTG location, which would cover the various jacket suction pile emplacement options for the WTG location. It was understood at the time that there were three WTG locations that required investigation, however that number could have been reduced or increased depending on the various factors such as weather conditions, OWF operations at the time and results obtained from the preliminary offshore interpretation. The SBI SAS data acquired was used to identify discrete anomalies interpreted to be subseabed boulders, with a minimum size criteria of 0.3?m in all dimensions to the maximum length of the record length below seabed.
