An umbilical connection for use in a hazardous environment like a floating roof storage tank has one or more hydraulic hoses, one or more electrical cables or a combination thereof. Each hydraulic hose has a static dissipative and abrasion resistant covering. Each electrical cable has an abrasion resistant coating. The hoses and cables are bundled and wrapped in a static dissipative and abrasion resistant open mesh sheath or an overbraid to form the umbilical connection.

Methods for remotely inspecting an internal floating roof and the seals associated with such internal floating roof project an illumination pattern from a series of substantially parallel laser beams onto the floating roof and/or the seal. Another laser beam projects at a predetermined angle offset from the series of laser beams. The illumination pattern and offset spot from the other laser are viewed through a camera. The length of a defect in the internal floating roof or seal or a gap between the seal and the tank wall is calculated as the length of a side of a right triangle based upon the predetermined angle and the predetermined distance between the lasers and the floating roof or seal.

A robotic ultrasonic inspection vehicle is provided with one or more transducers which are driven by a long, broadband excitation pulse for insonifying a sample subject to inspection. The long, broadband excitation pulse can be chirped. The robotic vehicle also can include a drive circuit for coupling the excitation pulse to the transducer. Data associated with the excitation pulse is used to gate off the drive circuitry at an appropriate time. The robotic vehicle may traverse a combustion prone region and therefore electrical parameters may be limited to intrinsically safe levels. However electrical parameters may safely be converted to higher levels so long as the conversion is inhibited to occur only after the vehicle has left a combustion prone region and entered a region of minimal risk of combustion.

A surveillance system for hazardous environments and the like having a radio remote controlled vehicle that is sized and shaped for optimum maneuverability and stability, including mobility on stairs and inclined surfaces. The vehicle is designed to have a low center of gravity that is shiftable up and down, front to rear and side to side under operator control in order to provide stability. The top deck of the vehicle is uniquely shaped and is adapted to support any of several payloads, including an articulated arm module that is moveable in a pan and tilt direction and a smear sampler mechanism for repeatedly taking surface samples. The vehicle is moved by independently operated, motor driven tracks located on each of the two longitudinal sides of the vehicle and is adapted to move in a forward, reverse and rotational directions. Remote monitoring is provided by stereoptic TV cameras, stereo sound, and variety of environmental sensors.

The present invention is an apparatus and method of preparing and inspecting a submerged surface of a fluid reservoir. The apparatus includes a chassis sized and shaped to provide an optimally low center of gravity, a propulsion system comprising two independently controllable motor and track means, a scrubbing/vacuuming system disposed at the front of the chassis which includes a scrubbing system designed to mechanically break up sediment on the surface beneath the apparatus and a vacuuming system to remove sediment and sediment-containing fluid from beneath the apparatus, and an inspection system located immediately behind the scrubbing/vacuuming system with respect to the direction of apparatus travel and operative to inspect the freshly cleaned surface with either ultrasonics, optics, or a combination of both.
