Kraken Bids on International Mine Hunting Upgrade Program

Kraken Robotic Systems Inc., won a prestigious navy bid for a new sonar systems for an unnamed international navy. The navy customer has notified Kraken that it intends to enter into a contract with Kraken after the expiration of a standstill period.This was a competitive bid process for upgrades of the customer’s mine-hunting equipment. Kraken was one of four companies whose offers were received and evaluated and all four bidders have been notified of the result.  Under the program, Kraken will deliver the KATFISH towed synthetic aperture sonar as well as autonomous launch and recovery

ROV Helps Recovery Dive Teams Locate Dumped Car

JW Fishers team has heard just about every story possible concerning sunken ships, hidden treasures, scientific experiments, unexploded ordinance, location of drowning victims, and missing evidence recovery. The tools we provide to the operators undertaking these tasks vary from metal detectors and sonar systems to Remote Operated Vehicles (ROVs).According to The Remotely Operated Vehicle Committee of the Marine Technology Society, “exactly who to credit with developing the first ROV will probably remain clouded, however, there are two who deserve credit. The PUV (Programmed Underwater Vehicle)

This will help the fishing industry save time and money, in addition to increasing the sustainability of the oceans, it added

French Frigate Sonars Get an Upgrade

sonars have been upgraded using RTsys AS3i technology (Analog Surface Ship Sonar Improvement), which digitalized and improved the processing of signals rendered by sensors.Brittany-based company RTSYS does not only deals with AUV, subsea recorders and buoys, but can also display a full range of sonar systems such as handheld devices for divers or sonar retrofit. The latter of which led the French SME to lately offer in summer 2017 its services to the French Navy by upgrading analogue sonars on four frigates.In accordance with the ACORES public procurement program (a French acronym standing for Frigate

Underwater Metal Detectors Get the Job Done

a ship's propeller dislodges from a vessel and falls to the murky bottom below? Most of the time, the operator does not have the necessary tools to find the missing equipment and must hire an outside diving company to aid in the search. These companies utilize a varying degree of equipment from sonar systems to underwater metal detectors.Marine Diving Service, which provides marine diving services to customers on the east coast of the United States, utilizes JW Fishers’ Pulse 8X in its daily operations. Marine Diving Service's salvage track record includes everything from small objects
