HAWAII MR1 Installation Aboard Vessels of Opportunity

The HAWAII MR1 Launch and Recovery System (LRS) has a footprint equivalent to a standard 20-foot shipping container, and is mounted on the aft end of the work deck. The towfish cradle tilts and slides to deploy and recover the tofish and depressor weight. To accommodate the movement of the cradle, the LRS must be mounted flush with the aft end of the work deck, and have 15 feet of overhead. Controls for the system's hydraulics are located on the starboard aft corner of the LRS, and clear access is required to both sides of the LRS during deployment and recovery.

 

 

The LRS contains ISO corner fittings that may be used to secure the LRS to the ship using twistlocks that can be welded directly to the workdeck. The LRS also features bolt holes spaced at 2 foot intervals that allow the LRS to be attached to angle brackets that can be bolted or welded to the deck.

 

 

The MR1 tow winch needs to be mounted at least 20 feet forward of the LRS to allow the tow cable to level wind on the drum as its hauled in. The winch can be bolted or welded to the deck. The hydraulic power pack should be mounted in a dry location within 40 feet of the LRS and winch. See MR1 Physical Specifications for power requirements and other exciting facts.

 

 

The MR1 travels with a 20-foot shipping container outfitted to serve as an engineering or data processing laboratory. On ships where the work deck is wet, the lab and other deck gear need to be lifted high and dry, with elevated catwalks to allow dry access and safe operation.
