Hydroid, A Kongsberg Company

Hydroid, A Kongsberg Company launched a new generation autonomous underwater vehicle at Oceanology International. This vehicle is an evolution of the world’s most popular man portable AUV. The new REMUS 100 is the perfect balance of design and technology. Known for being a leader in the field, this vehicle will provide data you can trust, field-proven reliability and modularity. A full-size display vehicle will be featured on the stand along with new videos and information about all their products.

In addition to the full-size model of the new generation vehicle, there was a 1/6 scale models of their current line of vehicles (REMUS 100, REMUS 600 and REMUS 6000). There were collateral and videos that focused on our new and current products and dynamic wall imagery. Additionally they will have information and video available on our unique Line Capture Line Release (LCLR) system for underwater docking and their underwater docks.

Naturally, they focused on the launch of their new generation REMUS 100 vehicle. This vehicle is the first in a whole new range of marine robotics products developed at Hydroid and based on their experience with the world’s largest AUV user community. This vehicle and other systems will be on display in a dynamic booth environment with videos and specialty display features.

Their exhibits are used by/of use to: Marine researchers, oceanographic, marine biology, environmental, hydrographic, defence and security communities, and of particular interest to those attending the Hydrography, Geophysics and Geotechnics; Marine Renewables; Ocean Observing Systems: Marine Technology and Services Sector Role in the Blue Economy; Oil & Gas: What’s next for Ageing Offshore Assets?; and Unmanned Vehicles and Vessels Showcase conference streams.

They recently launched the Line Capture Line Recovery (LCLR) system, a self-contained module that is initially offered on Hydroid’s REMUS 600 autonomous underwater vehicle for the purpose of autonomous launch and recovery.

A vertical line is deployed in the water with a transponder attached to the end of the line. When the vehicle is commanded to dock, the LCLR software autonomously homes the vehicle to approach the transponder. The vehicle navigates autonomously toward the transponder and attaches itself to the line above the transponder. The line and the attached vehicle are then recovered on a vessel such as an Unmanned Surface Vehicle (USV) or any other platform. The vessel may be stationary or moving during the capture process. The LCLR module uses a linear Digital Ultra Short Base Line (DUSBL) Acoustic Array for homing the vehicle to the transponder. The final capture is assisted by articulated arms for capturing the line after the vehicle reaches it. Upon capture, a latch mechanism attaches the vehicle to the line. An optical sensor is used to confirm the completion of the vehicle’s capture and initiate its recovery. During the approach of the vehicle to the transponder, the system Graphical User Interface (GUI) can send updates on the transponder position via acoustic messages to the vehicle. The GUI may be configured to transmit the position update to the vehicle automatically or manually by the operator. The LCLR system also works for moving captures, using GPS to determine the vessel’s position.

There will also be information on their autonomous underwater docking stations that allow for their vehicles to remain underwater for an extended period of time. In this system, their AUVs will use the deep sea docking stations to recharge batteries, send data back to shore and, if needed, undergo re-programming. Their AUVs don’t have to continuously return to the surface. The docking stations can be installed and remain underwater for over seven months. www.hydroid.com
