Feritech to launch new product set to revolutionise subsea geotechnical surveys
Feritech Global has announced the launch of a new product which is expected to create a step change in subsea geotechnical surveying. The Sealance brings the various functions required for geotechnical surveying together in one streamlined product, enabling significantly reduced timescales for projects.
The Sealance is an adaptable survey device offering simultaneous deployment of up to three geotechnical tools. It offers the most comprehensive range of equipment currently available on the market. Sampling can be achieved using the two powered feed systems, coupled with any two of the following tools: Vibrocorer, Cone Penetration Testing equipment, push corer or rotary coring drill. The Feritech heat flow system can also be deployed simultaneously.
Rob Ferris, MD of Feritech Global, says: “The new Sealance benefits from a bespoke twin tool deployment system with additional integrated heat flow, the first of its kind. Because two tools and heat flow can be deployed simultaneously, this greatly reduces the length of time needed to complete a site survey, especially in deep water.”
“Of course, reduced project time also leads to very significant cost savings. With the cost of hiring a vessel running anywhere up from £20,000 a day, saving several days on a project immediately delivers real cost reductions. We also expect that the Sealance will be smaller, lighter and less expensive than its competitors. The impact of this product on the geotechnical surveys market will be huge, delivering a step change in efficiency.”
Rob Ferris adds: “The Sealance will be a real gamechanger in specific areas of geotechnical surveying, such as for cable routes and pipelines.”
Feritech is a leader in geotechnical surveying and has worked for clients around the globe, including recent projects in Australia and West Africa. The company also designs and manufactures innovative products and opened a new £3 million Innovation Centre near Falmouth in Cornwall this year.
The Sealance will be available from Feritech Global from September 2022 and can be pre-booked for projects.
Rob Ferris says: “We believe the Sealance will completely redefine the way geotechnical surveys are approached in future. This is truly disruptive technology and paves the way for our next exciting development, a range of autonomous products within our portfolio.”
Intelligent Muscle at OTC
A new extremely powerful and intelligent electric manipulator can be seen on Saab Seaeye’s Stand 1406 at the Ocean Technology Conference, Houston, 2 – 5 May 2022.
The pioneering breakthrough is Saab Seaeye’s new eM1-7 seven-function all-electric work-class manipulator.
As powerful as a hydraulic equivalent, it is more reliable and more dexterous.
Seaeye eM1-7’s micrometre precision comes from each of its seven joints having extremely accurate force and position feedback coupled with their own smart distributed microprocessor for intelligent, intuitive and precision arm control.
Visitors to the exhibition stand can also hear more about other innovations that are changing the face of underwater enterprises.
Saab Seaeye’s innovative new environmentally friendly electric work vehicle, called eWROV, matches the power of a 250 hp hydraulic work class system, but is easier to operate, more precise, acoustically quieter, more reliable, needs less maintenance and has a much lower lifetime cost.
Already the world leader in electric underwater robotics, Saab Seaeye’s eWROV joins the largest range of electric robotic vehicles in the industry.
This includes the multi-role 3000m rated Sabertooth, the world leading roaming and hovering robot that can operate in both fully autonomous and tethered modes, enabling fully flexible dual operations from a single platform fitted with cameras, sonars and tooling.
Two Sabertooth robots have succeeded in finding the wreck of the Endurance, sunk 3000m below the Antarctic ice during Shackleton’s ill-fated expedition in 1915.
Hydromea launches a new underwater wireless optical modem LUMA X-UV
Hydromea is launching its new patent-pending subsea wireless communication modem LUMA X-UV. The LUMA X-UV can beam data at up to 10 Mbit/s in the presence of other light sources in the environment, enabling real-time streaming of HD-quality video and 4K images wirelessly through water. It will be a
critical tool for wireless control of underwater vehicles that have their lights on during missions or for deployments in shallow waters.
Felix Schill, co-founder and CTO of Hydromea, says:
“LUMA X-UV is another big step forward in providing unlimited access to subsea data. It is a tool with a lot of versatility built in. It can be used as a modem and as an access point in subsea infrastructure. Moving the data stream into the UV wavelength with LUMA X-UV, this modem will work in the presence of other light sources, such as ROV lights. It will also be the best communication tool in shallow waters where there is still a significant amount of ambient light.”
Igor Martin, co-founder and CEO of Hydromea, adds:
“Our LUMA modems are getting increasingly used across various setups and environments underwater. LUMA uses light to exchange data wirelessly, which means other light sources can create interference and reduce the effectiveness of such communication. Our new LUMA X-UV provides our customers with a perfect solution to this problem.”
Hydromea focuses its development on affordable, autonomous and miniaturized devices that can be used at any ocean depth for unprecedented data access. LUMA X-UV comes in a titanium housing with a serial and ethernet connection and will be pressure-rated to 6’000 meters depth.
Founded in 2014, Hydromea is a Swiss-based underwater robotics company helping its customers to have unparalleled underwater data connectivity and efficient remote inspection access to submerged assets.
OceanSENSE 4 – Detects All Subsea Fluorescing Trace Dyes
OTAQ Offshore is proud to announce the final word in subsea leak detection with the release of the OceanSENSE 4.
Designed to detect all fluorescing trace dyes used in subsea leak detection from a single 6000m rated Titanium housing, the OceanSENSE 4 utilises the same core technology as the industry standard OTAQ OceanSENSE subsea leak and cement returns detection system.
With two units purchased and in the field with two separate clients, the ROV mount OceanSENSE 4 enables operators to instantly switch between detecting different dye types ‘on-the-fly’ via the newly designed topside software. The ability to detect all dye types means there is no requirement to mobilise multiple detection configurations or recover the ROV to surface. OceanSENSE 4 is engineered to save operators time and money and to eliminate all risk associated with sensor and dye incompatibilities.
Utilising cutting edge technology OceanSENSE 4 is extremely capable. When mixing fluorescing dye into the carrier medium, the industry standard is 200,000 parts per billion – all OceanSENSE models detect dye to 6 parts per billion. The sensor feedback based topside software removes human judgement and inconsistencies from the detection operation. The OceanSENSE 4 unequivocally informs the operator when dye is present in the water column thus, depending on the application, locating the leak, confirming asset integrity or confirming the arrival of cement at the seafloor.
OceanSENSE was first released to the market in 2009, with operators rapidly positioning the system as the global industry standard for subsea dye detection. To date, OceanSENSE technology has achieved in excess of 50,000 offshore days on over 1000 subsea projects. The OceanSENSE 4 builds on this pedigree by ensuring increased operator flexibility while delivering repeatability of results, protecting the environment and reducing offshore operational costs.
Dr Harry Rotsch, inventor of the OceanSENSE range, expands; “as the industry looks to rebound from ongoing pressures and recent global events, the 4 dye detection system is the natural evolution of OceanSENSE. We have always looked to offer the best technical solution while responding to market forces. The system will continue to position OceanSENSE at the forefront of subsea dye detection for the rest of this decade”.

WASSP and SBG Systems to partner for WASSP’s new version of its world’s most cost-effective multibeam sonar
New WASSP S3r Multibeam Sonar
The new WASSP S3r is one of the world’s most cost-effective, professional survey and mapping multibeam sounder solutions. It combines data from a multibeam sounder transducer with 224 beams covering 120° degrees swath port-to-starboard along with position, heading, and motion to create an accurate bathymetric map of underwater features for various survey situations and environmental conditions. WASSP S3r is able to survey area up to 10 times faster than a single-beam sounder.
With the very high requirements hydrographic surveying has for accuracy, WASSP needed a solution for RTK + INS that could allow the sounder to create accurately positioned 3D bathymetric representations of the seafloor, down to centimeter accuracy with minimal passes. This demand combined with the complexities of tide, and boat movement mean that in order to get usable position and motion data, a dual antenna system was required. The company made multiple test scenarios from which the SBG Ellipse-D inertial navigation system came out as the best choice based on accuracy of consecutive test mapping.
“We required a cost-effective and high-precision position and motion solution. It needed to be able to combine with our WASSP multibeam technology so we could meet the high level of accuracy our customers expect” explains Bart Slingerland, Product Owner at WASSP.
WASSP has also incorporated the Ellipse-D into its S3Pr portable survey package where size, weight, and cost were also key factors in the final solution. The SBG Ellipse-D was able to fit into a covered housing that allows quick setup on small vessels and interface with the WASSP DRX processing unit and CDX software.
Ellipse-D, The Smallest RTK INS on the Market
The new Ellipse-D has been launched in June 2020. This miniature Inertial Navigation System (INS) provides RTK position, 0.05° attitude, and dual antenna heading. It also outputs a 5cm heave, that adjusts automatically to the wave period. This sensor is designed to be easily integrated into marine projects thanks to compatibility with numerous industry standards (TSS1, PASHR, INDYN protocols). Ellipse is the smallest heave sensor at this level of performance, and the OEM version allows the tightest integrations. “We are very proud to be part of WASSP S3r and S3Pr. WASSP innovative solutions makes multibeam sonar technology available to the largest professionals” to conclude Thibault Bonnevie, CEO of SBG Systems.
