Underwater Heavy Duty
Marine Net (UHDMN) is a marine
intrusion detection system based on heavy-duty sensor nets. The nets are made
of special sensor cable containing steel fibers and composite materials with
high durability in rough sea conditions. UHDMN is designed to prevent, impede
and detect underwater intrusions.
UHDMN can be integrated
with floating barriers, floaters, and sea gates as well as a sensor system to
detect attempts climbing over the nets above sea level.
The UHDMN nets consist
of a grid structure with optional sizes 20cm X 20cm, 25cm X 25cm or 30cm X
30cm openings.
The cables have a
diameter of 8.8 mm with the option to 14 mm and contain copper, steel fibers, and
composite materials fibers, coated with high durability polymers.
UHDMN has been designed
for durability and a longer lifespan out of materials that are mechanically
durable and able to resist corrosion by seawater and oil for many years.
UHDMN simultaneously
combines multiple detection technologies - including a unique special cable
structure which allows UHDMN a higher probability of detection, functional
reliability and redundancy in the case of damage or sabotage of the externally
coated polymers.
UHDMN's configuration is
engineered to be impossible to undo without cutting the net and thus triggering
the alarm.
- Adaptable to suit different security requirements
- Redundant detection capability, easy to repair in case of damage
- High durability and low maintenance requirements
- Built from modular net segments that allow for rapid repairs
- Will not signal false alarms because of severe sea conditions and
winds
- Uses controllers with two-way communication and test commands from
remote control rooms
- Can integrate with sea gates for ease of passage
- May be integrated with floaters or floating barriers to block
speedboats
- Prevents climbing above sea level (optional)
- Optional integration with underwater acoustic shockers
