Un-manned off-shore platforms are by their very nature exposed & vulnerable to intrusions. These unauthorized intrusions are not just a nuisance; they can be very costly in production down-time and lost equipment.

With the use of PIR motion sensors located around the boat landing platform it is possible to detect any unauthorized approach / access to the platform from seaward, once detected the intruder can be driven away using non-lethal Long Range Acoustic Devices (LRADs).

The acoustic energy being sufficient to cause actual physical pain and discomfort which only gets worse the closer they get to the rig. Wireless remote control allows maintenance personnel to switch the system on / off at a safe distance.

Protect against inadvertent entry into unauthorized spaces i.e. confined spaces, paint lockers, cofferdams, tank spaces…etc.
