Remote Instrument and Submerged Equipment Recovery
RISER is a remotely actuated subsea recovery system used by navies and oceanographers around the world. We offer many models for different applications, with timer and acoustic actuation variants for use with lift bags or burn wire recovery methods. The RISER system can reach depths of more than 600 meters with some models lasting up to 48 months on battery power.
Acoustic or Timer
RISER can be actuated acoustically from a top side deck box or via timer with either a countdown function or a specific date and time.
Lift Bag or Burn Wire
RISER can be outfitted with either a burn wire mechanism or a custom built lift bag and scuba cylinder.
Long Battery Life
RISER can handle multi-year deployments. Rechargeable or replaceable, we make sure RISER has the battery best suited for your application.
Because RISER either physically attaches to the payload or is built into instruments for recovery, the whole system will surface together. In most cases RISER will leave nothing behind.
RISER's remotely actuation reduces or eliminates the need for divers to be in the vicinity of the lift. There are fewer lines to pose tangle hazzards and the crew can keep a safe distance as the payload surfaces.
RISER is an excellent cost-effective alternative to expensive syntactic foam pop-up buoy solutions. RISER also eliminates pop-up buoy issues such as line entanglement and the need for proper orientation.
