IMI-30 will use existing HMRG deck hardware for launch, recovery, and towing operations. Deck hardware includes a towing winch, a Launch & Recovery System (LRS), a hydraulic power pack, and a 20-foot container that serves as a seagoing engineering lab. The system will be designed so it can be launched/recovered using A-frames or cranes in addition to the LRS. IMI-30 will use fiber optic telemetry, and will be towable from either the armored deep-sea fiber optic cable available on some UNOLS vessels, or from the portable UH fiber-optic cable and winch.
The commonality in deck gear between IMI-30 and MR1 will result in better reliability for both systems. This is anticipated because HMRG already provides for routine maintenance of the existing gear, and maintenance demands will not significantly increase for HMRG engineers with the addition of the new system. In fact, more regular use of the handling gear will eliminate problems that often occur after long periods of dormancy, thus improving the reliability despite the additional wear.
Data processing will be conducted using HMRG's network of Sun Solaris and PC linux workstations. HMRG provides a crew of four people to conduct all sonar operations: a survey chief, a system engineer, and two sonar operators. These four conduct all sonar operations, including all deck operations and system maintenance, real-time operation of the sonar, and shipboard data processing. No other personnel are required.
