Forum Unveils New eROV

Forum’s Integrated Control Engine (ICE) to bring greater functionality commonly only found in larger work-class vehicles.According to the manufacturer, the advanced control electronics pod fitted to all Forum XLe observation class vehicles enables superior connectivity and expansion capabilities. Ethernet interfacing allows for seamless integration with other industry sensors using common IP architecture and ease of remote data transfer.Kevin Taylor, Forum VP of Subsea, said, “As the subsea market continues to recover from a sustained downturn, cost efficiency is high on the agenda for the

New Ethernet Cable from TE

TE Connectivity (TE) introduced its Raychem Cat 5e cable that offers high-performance Ethernet connectivity at speeds up to 1-Gb/s in harsh military, marine and aerospace environments.The Cat 5e cable makes use of high temperature fluoropolymers that are designed to perform under extreme temperature fluctuations from -65°C to +200°C. Designed in accordance with ANSI/TIA-568-C.2, the cable is both lightweight and easy to terminate, the manufacturer said. TE’s waterblock variation uses super absorbent tapes and yarns that further help reduce weight, increase flexibility and lower installatio

The starboard and port side pontoons are core pieces, but the length, width and ground clearances can be changed by lengthening the idler sprocket brackets or changing out the connecting bridge. The current design includes two Ethernet

, building and qualifying a new autonomous ROV called ATOLL. It is designed to use machine vision technology to dock on subsea infrastructure. Because vision-based technology is critical to the autonomous docking of ATOLL, Forssea has developed a range of vision-based products, ranging from low-cost Ethernet cameras, adapted to augmented reality applications, to an enhanced vision product called ‘Polar X’, which improves the visibility factor and target identification in turbid underwater conditions by a factor of three.Forssea’s most recent development is V-LOC, which uses QR code

to predict timing of wave peaks and troughs and optimize the variable torque on the motor to minimize input disturbances through the tow cable.The operator can achieve manual control of the Tentacle Winch either through manual switch inputs similar to those in traditional systems, or remotely via secure Ethernet and Wi-Fi interfaces. A semi-autonomous mode allows for dynamic surge (front/back motion) and heave (up/down motion) compensation to minimize input disturbances on the tow cable even in high seas. A fully autonomous mode allows the KATFISH tow body to command the winch. As water depth increases

Indeed, BHGE is working on a battery powered DHSV, which is expected to be ready in 2020.Combining electrification with ethernet and fiber optic communications then enables that data to be readily available, real-time, so that data analytics can be applied for production optimization, condition monitoring and predictive maintenance.The shape of the communications and computing architecture – i.e. centralized or decentralized

enhancing users’ knowledge of the subsea environment.   In addition, where surface analysis of the telemetered data requires a more thorough review of sensor parameters, SMART enables acoustic recovery of raw data from specified time ranges. Alternately, the system can be coupled via an Ethernet connection to BlueComm (Sonardyne’s high-bandwidth through-water optical communication link), enabling larger quantities of data to be retrieved from an ROV or AUV. All logged data can be downloaded from safe storage when the unit is recovered.   The essence of SMART is flexibility
