Benthos Stingray ROV
The Teledyne Benthos Stingray
ROV is designed to be an afford- able, rugged, powerful, light- weight (72 lbs) high performance inspection class vehicle that is capable of working in high cur- rents and at depths to 400 m (750 m optional). It can be con- figured with as many as three video cameras, displaying images from two cameras simultaneously. With a total of 84 lbs of forward thrust, it has been designed to perform in the most demanding conditions and can be configured with numerous options including one, two or three function manipulator, scanning sonar, digital still camera, large- object recovery system, additional thrusters, additional buoyancy, custom tools, lights and sensors. The Stingray is designed to be easily interfaced with user supplied devices and sensors via RS-232, RS-485, analog and digi- tal interfaces. An optional fiber optic communications link is offered for operations requiring a long tether.
Applications include port and harbor security, ship hull inspections, in-situ biological sampling, dam and tunnel inspections, under-ice surveys and operations, internal and external pipe inspections, inspections of nuclear reac- tor facilities, marine casualty investigation and salvage operations, offshore structure surveys, inspection of water tanks and systems, search and rescue operations, police evidence search and recovery operations, monitoring of marine construction projects and artificial reef monitor- ing operations.

PSS Sells Two Triton XLS ROVs
Systems (PSS) said that Deep Marine
Technology, Inc. (DMT) has purchased two additional Triton
XLS Systems, XLS 21 and 22. The two new
ROVs will be config- ured with 15-in. thrusters, 150 HPU with 30 HP auxiliary
HPU, station keeping capabilities and enhanced survey suite interfaces including
Ethernet. The system will be configured for heavy-work operations and includes 600 m neutral tether on the
Tether Management System. The ROVs will be installed onboard DMTs new 300 ft. MSV the DMT Emerald which is expected to be in service in November 2006.

ROVs for Dam Inspections
In the past, inspecting hydoelectic dams was difficult and expensive due to the need to put divers in the water. Today, more companies are using ROVs to per- form inspections, allowing them to perform an inspection whenever they want, and JW Fishers ROVs have become a popular choice for these inspections.
Ontario Power in Toronto is one of the companies that routinely inspect their dams and adjacent structures using an ROV. They used Fishers SeaLion ROV for inspection operations at several of their hydro plants. Spokesman Mike Ostroski said, "In our Smokey Falls plant in northern Ontario the SeaLion inspected tail- race concrete piers, went up the draft tube to the underside of the runners, inspected the headworks concrete, and checked for erosion under the sluiceway aprons. At our Sir Adam Beck plant we inspected the headworks concrete piers, the headgate, and its gains on one of the units. We've found the ROV to be an effective tool for this work and it has quickly paid for itself. One advantage of the ROV is that we don't have to shut down the units on either side of the one being inspected, letting us maintain a higher operating capacity. Also, we can put it in on the down- stream side of the trash racks and it's perfectly safe."
