UK-based Rovco has successfully completed a subsea cable survey and inspection for the world’s largest and most technologically advanced offshore renewables test site, Wave Hub. The inspection programme included the first commercial trial of Rovco’s 3D visualisation technology to create scaled, high resolution models of subsea infrastructure with millimetre accuracy.
Rovco also delivered a detailed bathymetric survey utilising a state-of-the-art multibeam echosounder (MBES), alongside an ROV video inspection with ultra-short baseline tracking for Wave Hub’s entire offshore cable network, off the coast of Saint Ives Bay, Cornwall.
The 3D system, collects raw data which is then processed to obtain 3D volumetric information, ensuring a true representation of the underwater environment. With short mobilisations and no need for large specialist vessels or technical support teams, the system generates cost savings of up to 80% compared with traditional survey methods.

Global subsea equipment specialist, Ashtead Technology has successfully delivered an advanced subsea laser scanning project for Subsea 7 on Chevron’s Captain field located in the UK North Sea. The project saw Ashtead carry out a well inspection utilising Newton Lab’s M210UW and M3200UW subsea laser scanning systems.
Ashtead designed and engineered bespoke deployment tools that enabled the scanning systems to accurately capture subsea scans at water depths of 110 meters using divers. The scope of work included an internal casing inspection and a horizontal mapping survey to capture more than 100 short and long range scans. This allowed Ashtead to successfully generate a 3D model of the structure with sub-millimetre accuracy.
The subsea laser scanning systems were fully tested at Ashtead’s purpose built facility in Westhill, Aberdeenshire before undergoing a simulated dry-run for the client ahead of deployment. The project was mobilised within two weeks of the contact being awarded and was completed on time and within budget.
The contract marked Newton Labs’ first subsea project using its recently launched M3200UW laser scanner. The system can operate with either a scanning or a fixed laser line to measure underwater objects to 0.02 millimetre accuracy. Designed for ROV or diver deployment, the tool is fitted with a high resolution camera, allowing data to be streamed live, in real-time for maximum efficiency.

If their locations are not precisely known, the presence of unexploded wartime ordnance in the sea can present an obvious hazard, such as during the construction of offshore grid connections, and, in particular, during the laying of cables to bring offshore wind energy to shore. HR Wallingford has been using its Fast Flow Facility to help TenneT and the University of Rostock to obtain data that will help to predict the movement of unexploded ordnance in the North Sea.
Potential sites for offshore cable routes and platform locations undergo a dedicated unexploded ordnance (UXO) survey, often followed by the identification and disposal of debris and, in a few cases, of UXO prior to installation. While these surveys allow UXO locations to be pinpointed on a particular date, the action of currents and waves may mean that the UXO migrate over time, making it necessary to repeat these UXO measures, for example in the case of a cable repair.
Funded by TenneT, the University of Rostock in Germany has developed a model of unexploded ordnance movement for which it has already conducted small-scale modelling at the University. Now, with co-funding from TenneT, a leading European electricity transmission system operator (TSO) that supplies electricity to 41 million end-users in the Netherlands and Germany, this new project is seeking to generate large-scale data to better inform and validate this model.

Aberdeenshire-based ROV solutions provider, Aleron Subsea has boosted its track record by recently taking part in a salvage project in the Atlantic Ocean, utilising its AUXROV subsea system.
Aleron and the AUXROV were selected by James Fisher Marine and Britannia’s Gold Ltd to assist with a high-profile salvage operation, targeting wrecks that were sunk during the First and Second World Wars. During both wars, some 7,500 merchant ships were sunk of which approximately 700 were identified as carrying shipments of gold under UK Government direction.
Britannia’s Gold Ltd has been established to finance the recovery of targeted cargoes and return them to the UK for the benefit of the government, investors and merchant marine charities. This inaugural salvage work scope takes place after 25 years of planning, and the successful completion of a significant crowdfunding campaign.
The AUXROV work scope comprised over 850 lifts, moving over 500 tonnes of debris with three different hydraulic grabs, and providing real time information on the grabbed materials. During simultaneous operations with two work class ROV systems, it then provided power and assistance in dredging operations on the wreck. Remaining in the water for up to 90 hours at certain stages, the AUXROV was able to enter several constrained, hard to reach areas of the site assisting in the overall efficiency of the operation.

N-Sea and University of Strathclyde collaborate for practical implementation of deep learning for subsea video annotation
Integrated subsea service provider, N-Sea, and the University of Strathclyde’s Institute of Sensors Signals and Communications at the Department of Electronic and Electrical Engineering, have developed a deep learning video annotation model for automatic eventing of subsea survey video.
The project is supported by The Data Lab Innovation Centre with the collaboration by combining the state-of-the-art inspection expertise of N-Sea and the innovative data analytics research at the University of Strathclyde.
The algorithm developed by the project annotates video frames from three general-purpose ROV cameras, automatically and in real-time. Whilst time consuming, the task of identifying events in the video footage is relatively straight forward for an expert operator. However, results are frequently affected by sand agitation, sea-life or vegetation. The approach taken by the project team utilises ensembles that combine the output of three classifiers operating on the three video streams, port, starboard and centre independently.

The ease of integration of payloads into the Riptide product line of UUVs has been a key value proposition for diverse customers. This flexibility was recently demonstrated by the rapid integration of a new sonar and a WiFi data system.
Riptide recently participated in a US SOCOM effort to evaluate diver assistance aids.
In this program a Klein 3500 Combined Side Scan and Interferometric Sonar was integrated into a Riptide 1MP 1 Man Portable 7.5” (190mm) diameter UUV/AUV in less than 4 working days. This rapid integration was followed by successful field demonstrations.
The Klein 3500 is an excellent example of the high-performance sensors that can be easily integrated onto the Riptide UUV/AUV platforms. The combined data set of the 3500 has been shown to increase the Probability of Detection (Pd) for small and difficult targets, providing an effective alternative to the size and complexity of a Synthetic Aperture Sonar (SAS).
In a second situation, Riptide was provided with a µUUV® payload section containing an underwater WIFI sensor installed by the instrument manufacturer. Riptide added nose and tail sections to this third party produced payload section and, the vehicle then completed demonstrations of the underwater WIFI in both a pool and offshore operating environments.

The oil and gas industry has just 18 months to upgrade critical release hook systems on offshore lifeboats to meet new regulations imposed by the International Maritime Organisation (IMO) to improve safety at sea. According to the organisation, the number of failures during drills and inspections which resulted in casualties or injured crew members has been unacceptably high. Launched in 2011, the IMO regulations state that lifeboat release and retrieval systems must be evaluated and replaced no later than 1 July 2019. This will involve the complex and costly removal, retrofit and replacement of lifeboat systems globally.
Ampelmann is offering its Atlas motion-compensated lifeboat exchange system to the oil and gas industry to provide a faster, safer and more cost-effective alternative to traditional procedures which can be performed within a wider operational window. The Atlas system can also be used to transfer large pieces of equipment and delicate or complex cargo as well as replacing lifeboats to meet personnel on board (POB) requirements.
The Atlas system involves the lifeboat being lowered directly onto the cradle of an active heave compensated installation system located on the deck of the supply vessel. The hexapod absorbs any vessel movement in significant wave heights up to 3.5 metres, while the davit retrieves the lifeboat from a fixed horizontal position. It can also be used for multiple change outs across several assets within the same operation, both on conventional and free-fall lifeboats.
The Britice-Chrono project is a five-year £3.7m UK Research-Council-funded project, aiming to gather data that reveals key details of past movements of ice shelves on Earth. The project joins leading scientists at nine universities, the British Geological Survey (BGS) and the British Antarctic Survey (BAS).
Following two years of studying the samples collected both onshore and offshore, the first results have been published. Dr Tom Bradwell of the University of Stirling collected high resolution (c.70 micron per pixel) X-ray images, using the Geotek XCT at Geotek’s specialist core logging laboratory, based in Daventry, UK.
The high resolution X-ray images of glacial sediments were critical to observing the plethora of thin laminations of mud, silt and sand which have settled out of meltwater from the front of an enormous partly-floating glacier. Non-destructive X-ray imaging of these core samples also enabled the identification of shells useful for age dating of these sediments and gravels that have fallen from icebergs and ice sheets thousands of years ago.
The X-ray scan collected from the Geotek XCT by Dr Tom Bradwell will be analysed by his team to help improve forecasts for the future of decaying ice sheets in Greenland and Antarctica.

Subsea Industries’ glass-flake, non-toxic hard coating Ecospeed has been chosen to protect the exhaust scrubber outlets of three newbuild container vessels building at a yard in Zhoushan, China.
A durable coating was required, with the ability to withstand the very high exhaust gas temperatures and the chemical pollutants encountered in this application. Scrubbers are intended to filter out oxides of sulphur and harmful hydrocarbons, soot, particulates, heavy metals and ashes to prevent pollution of the atmosphere. Some scrubbers, such as those fitted to these vessels, can also reduce the amount of nitrogen oxides and carbon gases.
However, according to Subsea Industries, some shipowners have experienced damaged pipework at the outlet end of the scrubber system due to the highly corrosive wash waters produced during the exhaust gas cleaning process.
Ecospeed’s durability has been proven by the fact that classification society DNV GL awarded it the highest B1 classification following tests of its suitability as a ballast tank coating. B1 is the superior grade in a six-grade classification system.
Independent research has shown Ecospeed to be 100% toxin-free, with no adverse environmental effects resulting from its use or application, unlike other coatings which can contain biocides, copper or tin compounds.

Hydrex recently carried out a repair to a crack in the port side grey water tank of a 145m chemical tanker. The damage was permanently repaired by Hydrex technicians, using an insert, during the vessel’s routine port call in Amsterdam.
The Hydrex team of diver/technicians began by carrying out a comprehensive inspection of the damaged area, working both underwater and onboard. The crack was found to be 480mm long, and had split in two at the port side end. The proposed repair was discussed with the vessel’s superintendent and the attending class surveyor, the decision being to install an insert, 700mm long and 300mm wide.
The engineers took measurements of the rounded hull shape using a special frame. This enabled a steel mobdock to be fabricated that would precisely fit the hull profile. The mobdock and insert plate were both rapidly made from stock materials at the fast response centre of the Hydrex headquarters in Antwerp, and transported to Amsterdam without delay.
The Hydrex team on site installed the mobdock and cut away the metal surrounding the crack, including part of the frame above the crack. The diver/technicians then positioned and fixed the new insert plate, using the Hydrex class-approved full-penetration welding procedure. After the newly-fitted insert plate had been closely inspected and approved by an independent NDT (non-destructive testing) inspector and the class surveyor, the Hydrex team reinstated the frame over the affected area.
