MARCH 22--A FusionPro 1RU MultiViewer from Zandar Technologies (Dublin, Ireland; www.zandar.com) has been installed onboard the DMT Diamond vessel for Deep Marine Technology (Houston, TX; www.deepsubs.com). The supply and sale of Zandar equipment was through Industrial Audio/Video (Houston, TX; www.i-a-v.com) and Bock Associates (Irving, TX; www.bockassoc.com). Built in 2005, the DMT Diamond is a 240-ft, Class II multiservice vessel used to carry out subsea construction and field-development work, deepwater intervention tasks, remotely operated vehicle surveys, and umbilical installations for oil and gas companies in the Gulf of Mexico.

"When putting together the features to operate a subsea construction vessel in the Gulf of Mexico, it was essential that our monitoring system be comprised of the latest technology," explains Jeremy Herndon, project manager for the DMT Diamond. "As a result, we chose the Zandar MultiViewer based upon its ability to take composite video, computer VGA inputs, and geoseismic data and combine them on a single screen. The benefits of getting a clear picture in the combination of computer and composite feeds enabled us to save vessel control center office space," Herndon adds.

Up to eight high-resolution cameras monitor each subsea project. Live images are transmitted to the Zandar unit via fiberoptic cable for display on a front projection system at a resolution of 1024 x 768. The image is then recorded to DVD and audio commentary overlayed. DVD images are provided to clients for feedback and record-keeping purposes.

"The FusionPro 1RU MultiViewer accommodates a choice of processing cards and associated I/O, enabling users to combine analog video, SDI, HD-SDI, RGB computer sources, DVI sources, and audio in one system," says Deirdre Smith, CEO at Zandar Technologies.
