Protecting Ships, Passengers & Crew


In response to the deadly October 2000 attack on the USS Cole, LRAD Corporation created the acoustic hailing device (AHD) market by developing its proprietary Long Range Acoustic Device technology and systems.

LRAD resolves uncertain situations and saves lives on both sides of the device by broadcasting highly intelligible communications and warning tones with focused acoustic output to clearly determine the intent of vessels not responding to radio calls, change threat behavior and enlarge vessel standoff zones beyond 3,000 meters.

Using attention commanding voice commands and deterrent tones to safely establish and enforce large standoff zones, LRAD systems unequivocally determine the intent of security threats and provide maritime security officers more time to initiate an elevated response to unauthorized incursions if necessary.

Navy

Naval forces throughout the world are equipping their fleets with LRAD systems as an essential component of their escalation of force (EOF) protocols. In uncertain situations, the EOF is increasingly initiated through hails and warnings broadcast by LRAD systems to potential threats and intruders.

LRAD provides captain and crew more time and distance to determine intent and distinguish between intruders, terrorist threats, fishing boats or commercial ships, and respond appropriately.

LRAD’s broadcast range exceeds the CINCLANTFLT Naval Vessel Protection Zone for standoff distances for ships pier side, at anchor or in restricted waters. LRAD’s unmatched acoustic performance is also used to conduct interdictions at sea, for UNREPS, and other naval duties.

Coast Guard

Coast Guard services are experiencing increasing territorial water incursions and homeland security threats. LRAD’s attention commanding voice broadcasts and warning tones enable coastal defense personnel to determine the intent of vessels not responding to radio calls and enforce marine and littoral zone regulations.

During suspect boat interceptions, LRAD systems ensure the Coast Guard’s commands and instructions are clearly heard and understood over engine, wind and background noise.

Naval Bases

The U.S. military employs LRAD-RX systems for perimeter security and enforcement of exclusion zones around certain naval bases including the Bahrain Naval Base pier.

Ports

The Ports of Corpus Christi, Texas, Ras Laffan, Qatar and Aqaba, Jordan installed advanced security systems featuring the LRAD-RX to broadcast multilingual hails and warnings to inbound ships not responding to radio calls. The LRAD-RX reduces false alarms and port security response times associated with confirming or denying port entry.

Maritime Facilities

LRAD-RX systems provide maritime facilities enhanced perimeter security to more effectively protect personnel and assets.

LRAD systems are in use in more than 70 countries around the world.

Coast Guard

7th Transportation Group USCG Report

“In all cases, when the TSV employed the LRAD in a: NL, vessel identification/intent, force protection mode, or hailing an escort, they always had a positive response on it’s operation and capability. Hailing at ranges of up to 1300 yards to an escort vessel is no problem.”


Columbian Coast Guard

The Columbian Coast Guard installed LRAD 300X systems on their coastal defense patrol boats for extended range communication during suspect boat interceptions.

LRAD ensures commands and instructions broadcast from Colombian maritime security vessels are clearly heard and understood over engine, wind and background noise to safely create large standoff zones and avert deadly confrontations.

Commercial Vessels


C Handy
During the week of Feb 28, 2012, the captain of the Taiwan vessel C Handy confirmed an LRAD system was used during a confrontation with pirates allowing the C Handy to cruise through Somali waters safely.

M/V Maersk Alabama

In a May 2009 Senate Subcommittee Hearing on Piracy on the High Seas, Captain Richard Phillips of the Alabama called for LRADs as an element in a “…comprehensive, multi-faceted plan to combat piracy”. He was proven right when the Alabama successfully deployed LRAD along with other defensive measures to deter a pirate attack off the northeast coast of Somalia in November 2009.

M/V Resolve & Sunshine Sky

Repelled Attack at 1,100 meters – “…aimed her (LRAD) using the sight, went to maximum power and volume and activated. The first time the boat seemed to fall off course momentarily, then come back. I activated the unit a second time, this time holding it for a longer period and “waving” it across the target to make sure I “hit”. The boat instantly went dead in the water and broke off its attack. The range was estimated at .6 to 8 nm. The crew all saw it and they were cheering. I now have a ship full of believers. Lessons learned: It works.” 
- Captain M/V Resolve

M/V Green Ridge

Repelled Swarming Attack at 225 meters – “There was a group of five small speed boats disguised as fishermen. Then two of them took off towards us. The captain called the mate on the radio to get the LRAD over to the port side. Once the boats got within 1 mile of the ship we turned on the LRAD. The speed boats got within 500 to 250 yards of the ship before stopping.” 
– Mechanic M/V Green Ridge

MSDF Harusame

The Harusame sighted a suspicious small boat approximately 3.5 nautical miles off its starboard bow in the north-north-west direction. The Harusame hailed the vessel with LRAD and launched its on-board helicopter to verify the status of the boat.

Cable Laying Vessels

“By the way our ship…has had to use her LRADs 4 times in the last week to warn fishing vessels to remain clear of our cable track. Each time, the fishing vessels responded immediately. We are using a warning we had translated into Egyptian when we hailed them.”

Port Security

The Ports of Corpus Christi, Texas, Ras Laffan, Qatar and Aqaba, Jordan installed advanced security systems featuring the LRAD-RX to broadcast multilingual hails and warnings to inbound ships not responding to radio calls. The LRAD-RX reduces false alarms and port security response times associated with confirming or denying port entry.

Oil & Gas Platforms

LRAD was installed on the Perro Negro 3 to communicate with ships approaching the OPLAT. LRAD is utilized to broadcast warnings and commands to fishing boats, keeping them away from the OPLAT. LRAD is a vital capability in a layered OPLAT security plan.

Gulf of Mexico – Platform Dive Operation

The Sang, a 75 ft. fishing boat, entered a Chevron dive area. The dive operator immediately initiated radio calls ordering the Sang to change course due to divers in the water. After receiving no reply from the Sang, blue smoke flares were fired, but to no avail. The dive operator then used an LRAD to broadcast pre-recorded English and Vietnamese warnings to the Sang. The Sang immediately stopped, retrieved its nets, turned 180° and left the area.

Before LRAD, flags, lights and flares were used to deter encroaching boats without much success. After testing verified a 2000-meter communication range, Chevron now requires LRAD 500X systems on all lift boat dive operations.

Cruise Ships & Yachts

Seabourn Spirit

Carrying 151 passengers, the Seabourn Spirit was attacked off the coast of Somalia in November 2005 by two skiffs with support from a mothership. RPGs and guns were fired at the Seabourn Spirit during the attack. The crew and security team used LRADs and fire hoses to prevent the pirates from boarding. The USS Gonzalez assisted the Seabourn Spirit in the attack’s aftermath.

“The security team also did well. Under fire, they charged fire hoses to keep the pirates from boarding, they assisted passengers to get them inside the skin of the ship, and they deployed LRAD. The Security Officer was particularly enthusiastic about the performance of LRAD, and in his opinion it saved the day.” – CO USS Gonzales

Spirit of Adventure

Sailing in the Indian Ocean in January 2011, the Spirit of Adventure deployed its LRAD system as part of its defensive measures that successfully turned back pursuing pirates.

Perimeter/Fixed Site Security & Response

LRAD-RX systems are being deployed around the world by maritime agencies for perimeter surveillance and security applications. Current systems with cameras, thermal imaging, motion detectors and other sensors only watch.

The remotely operated LRAD-RX provides the vital ‘first response’ capability missing from observe-only integrated security systems. Operating across an IP network, the LRAD-RX turns passive surveillance systems into remote first responders by identifying, warning and deterring potential security threats from the safety of command and control centers, creating a fully operational unmanned perimeter security solution.

Using powerful, highly intelligible voice commands and deterrent tones to safely establish and enforce large standoff zones (up to 3 kilometers), LRAD-RX systems determine a security threat’s intent and provide maritime security officers more time to initiate an elevated response to unauthorized incursions if necessary.

Featuring an integrated zoom camera, high-intensity searchlight and an IP-addressable full pan and tilt drive for precise tracking and targeting, the LRAD-RX can also be integrated with radar to provide automated intruder alerts. By turning passive surveillance systems and command and control centers into remote first responders, the LRAD-RX provides a permanent perimeter presence, reduces false alarms and protects maritime security personnel from potentially deadly situations.

Oil & Gas Platforms



Oil & gas platforms make ideal areas for seabird roosts that cause significant sanitation issues and property damage. Manned and unmanned platforms also face safety and security issues when fishing boats get too close. Birds perch, feed and nest on unmanned platforms causing significant guano-related health concerns for maintenance workers and expensive cleanup costs.

The high costs of cleanup and repair due to wildlife-related damage, large penalties and bad publicity associated with harming wildlife, and the ineffectiveness of legacy deterrents, highlight the need for safer, more effective wildlife preservation and control solutions.

Originally developed for defense and public safety applications, LRAD systems are now in use around the world to more effectively preserve and control wildlife. Featuring advanced directionality and several volume settings LRAD is easily programmed to broadcast a wide variety of tones and predator calls to ensure against habituation and safely deter wildlife and fishermen from close range up to 3 kilometers.

When integrated with cameras, motion sensors, night vision and radar, LRAD-RX systems can be automated and remotely operated across an IP network providing platform operators a completely unmanned perimeter protection solution capable of safely deterring wildlife and human incursions.

By implementing LRAD systems into oil & gas platform wildlife control programs, birds are safely dispersed and move on to more suitable nesting grounds.
