Ven-Tech Subsea supplied a four-man commercially licenced dive crew with supervision for the underwater examination …

Outfall Inspections

The engineers, technicians, and pilots of Ven-Tech Subsea’s ROV team have examined outfall inspections domestically over the last decade. It’s crucial to have adaptable equipment when working in low-light outfall inspection conditions so that it can handle any difficulties. Utilizing our internal underwater robotic facilities and manufacturing shops, our carefully trained and experienced crew customises and tests new ideas. Visionary solutions development and delivery have always been a source of great passion for Ven-Tech Subsea. In order to fix a leak in the Deep Sea Outfall, which is situated in Newfoundland, Ven-Tech Subsea worked on devising and implementing an efficient repair technique in 2020. The site’s environment offered difficulties, such as diving inside the ocean outfall and accurately operating a ROV from a working vessel in waves as high as seven feet. As a result, not only was a new grout mixture created specifically for deep water pipe leak repairs, but also a new application technique for internally fixing deep water pipe breaches that are not dewatered and a visual imaging system to track the repair’s progress. Ven-Tech Subsea collaborates with its clients to manage their systems in a cost- and efficiency-conscious way. During an underwater condition evaluation, our fleet of programmable ROVs equipped with 2D and 3D sonar and high-resolution video may find any irregularities. For our clients, spotting potential issues before they happen is crucial. If there are any problems with conducting a thorough tunnel or pipeline examination, Ven-Tech Subsea is ready to help. This includes gathering data to help with future maintenance programmes and documenting tunnel conditions for regulatory agencies. Data collection can be done with little to no outage needs thanks to remote intervention techniques. For more than 10 years, Ven-Tech Subsea has offered inspection, maintenance, and repair services to clients in the commercial, industrial, and municipal sectors as well as the oil and gas industry.  To find out more, call us right away.

Underwater ROV Inspections

Our ROV technicians encounter many environmental difficulties during their Underwater ROV Inspections during winter. Unexpected weather changes, frigid temperatures, and less-than-ideal environments can cause delays or have an effect on a team’s health and safety during Underwater ROV Inspections. The success of a Underwater ROV Inspections as well as the safety of our field workers depend on careful project preparation.  So how do you cross a frozen lake securely to get to an intake? or use wet equipment in temperatures below zero? You sometimes can’t just release a ROV from a typical launch point when you need to get to a specific spot that is surrounded by winter construction or other barriers. Last winter, one of our ROV teams faced a difficult task: getting to an intake that was only a few feet below the frozen lake’s surface. The frozen water above the intake made it impossible to access the area as well. The answer to this problem was to cross the frozen lake in a helicopter to get to the destination. The client entered the location and forced compressed air through the tunnel. This approach helped staff members find the input while also breaking up the internal ice. The ROV Team and their equipment were delivered to the location by helicopter.A variety of sensors that are capable of 3D modelling, HD video, video stills, photogrammetry, and sound imaging can be added to Ven-Tech Subsea’s remotely operated vehicles. Our fleet actually contains ROVs with a …

Remote Inspection Services

At Ven-Tech Subsea, we take pleasure in disseminating news about emerging technologies and images, especially Remote Inspection Services. This includes showing our fleet of autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs) for Remote Inspection Services, particularly when they are in use doing remote inspections in the real world.  In addition to being fun and interesting, ROVs are a crucial tool for deploying the technology we employ to collect data.  A condition evaluation is only as good as the information it includes when it comes to finishing an inspection of your underwater assets.  Both the technique for gathering data and the platform for deploying it are covered by remote inspection technology.

Large ROVs can tether travel far distances, all the while transmitting …

Effective underwater maintenance and repair plan depends on accurate data

We frequently hear the phrase “ageing infrastructure” these days. Our infrastructure is under strain from a number of factors, including climate change, rising urbanisation, and environmental dangers like 100-year weather events, which have a 1% chance of occurring. In order to monitor and maintain the structural integrity of underwater infrastructure including dams, tunnels and pipelines, intakes and outfalls, piers, and …

Underwater Inspection and Repair

Underwater Inspection and Repair of a Steel Pile Wall A group of Ven-Tech Subsea’s ROV technicians responded when an Underwater Inspection and Repair of a pipe in Edmonton, Alberta needed an underwater examination and repair. They gathered the information and gave our customer a thoroughly thorough state report of the Underwater Inspection and Repair. A sonar setups were employed during this underwater survey to find and pinpoint areas of interest. Any indications of erosion that had taken place since the pipes last inspection were of particular relevance.  The sonar side scan was placed on a Universal Sonar Mount by Ven-Tech Subsea ROV technicians. The technologies were then used to conduct a multibeam survey along the pipe, with the survey vessel being specially outfitted for the task. On damp surfaces, side scan sonar frequently detects biofouling or biological fouling. Therefore, it was assumed that there was no biofouling on the piles.  The client was given a baseline of data and a report from the analysis before the Underwater Inspection and Repair as preparation for subsequent inspections. But it also highlighted places that required immediate repair. Large groups of debris were visible spread throughout the riverbed in images as well. Large timber or trees made up the majority of them, with rock and gravel appearing in other locations. The repairs necessitated underwater welding, as the underwater inspection revealed. The repairs were done by commercial divers who are certified and trained by Ven-Tech Subsea. The chore of welding filer strips in the spaces between piles and a steel beam fell to divers who were outfitted with a surface-supplied air supply. Any structural flaws or weaknesses are slowed down by the addition of sealing material.  Ven-Tech Subsea deployed a four-person dive crew to this project to complete the repairs. To make the daily diving routine easier, this team included a diver, a diving supervisor, a standby diver, and a diver’s tender. The Diving Supervisor’s job is to oversee and continuously keep an eye on the diver’s progress.  The Diver Certification Board of Canada has qualified the diving staff at Ven-Tech Subsea (DCBC). According to the CAN CSA 275.4 Competency Standard for Diving Operations, this is acceptable. A support barge was also employed by the divers as a work platform. The dive crew now had more deck space and plenty of room for their gear as a result. Working underwater can present particular difficulties.  Due to the freshet, diving operations were scheduled during high/low water periods. This may not always allow for precise estimates of tidal and sea currents. During the repair, the underwater visibility ranged from nothing to about 25 mm (1 inch).  Technology is crucial for condition evaluations when it comes to underwater inspections and repairs. Sonars locate precise locations of damage, scour, erosion, and accumulation of debris. They offer a starting point for upcoming inspections. Additionally, they offer useful information by pointing up places that require quick maintenance.  When evaluating and fixing their submerged assets, Ven-Tech Subsea is able to provide our clients full-service alternatives because to the combination of our in-house services.
