Subsea Lasers

The Imenco Angel Shark T6 Subsea Laser is the most powerful green line laser available in the market. Primarily used for subsea pipeline inspections. By mounting two lasers in a fixed bracket, calibrated at a set distance, measurements can be picked out from subsea video.

The IMENCO Underwater Green Laser is intended for ROV use only where measurements are needed from video images. The green light ensures good visibility even at long distances due to less absorption of green light in water.

By paralleling two lasers, calibrated at set distance, accurate measurements from video images is possible. The 150 mW, 532 nm Green Laser is built into a stainless steel housing with a depth rating to 3000 meters of seawater. Due to the light intensity, it is clearly marked and personnel working with or close to the light source should be made aware of the dangers involved if looking straight into the light path. For a comparison, the laser is more than 20 times stronger than a normal laser pointer and should be treated with great care.

The RTS Green Line Laser produces a straight green line with uniform intensity over a long range, made possible by its wavelength enabling maximum water penetration. Aligned laser setup provides excellent accuracy for close range inspection and measurements.

The RTS Green Line Laser is designed to ensure exceptional stability under varying and challenging operation conditions.

Seatronics and Voyis have partnered to develop a subsea laser scanning package that incorporates all sensors required for high precision data collection, reducing the complexity of equipment mobilisations.

The rigid aluminium frame is fitted with the Insight Pro (4000M Rated) system from Voyis, as well as a host of High-Precision Survey Grade sensors to capture data on-the-fly with vast scan coverage and sub millimetric accuracy.

The Dynamic Laser Scanning Skid is fully equipped with all sensors that are needed for high precision dynamic survey, but with portability in mind. Incorporated in the Dynamic Laser Scanning frame are pre-fabricated brackets that are dimensionally controlled to provide lever arms and offsets prior to survey. With the incorporation of a Multiplexer on the system, the user is only required to provide a PPS pulse, a spare single mode fiber and 110V power to the Multiplexer bottle. This allows ease of use and reduces mobilization times. The frame was designed with a small footprint in mind, so that it could be installed on a variety of vehicles from mid-class inspection, to work class vehicles. The Dynamic Laser Scanning Skid is delivered fully integrated with all cabling between the sensors, to provide a fast deployment solution for gathering high precision data dynamically.
