Gull problems at the maritime terminal solved with laser bird deterrent - Case Study
- Location: Quinteros, Chile
- Application context: Installation of Agrilaser Autonomic at a maritime terminal
- Problem definition: Security risks and maintenance costs due to gull droppings
- Bird species: Gulls (Laridae)
- Time of the year with bird problems: All year round
- Time of the day with bird problems: From dusk till dawn
- Number of systems: 1 x Autonomic 500
- In use since: August 2018
- Laser projection area: 7000 m2 (1,73 acres)
- Bird reduction after the Autonomic’s installation: 70 %
The gull presence at the Quintero Bay location has been reduced by 80% since installing the Agrilaser Autonomic laser bird deterrent in August 2018.
“In Quintero we have three major problems with gulls: they cause safety issues, high maintenance costs and operational troubles.” He adds: “Some time ago we controlled the gulls with falconers. This was not an efficient solution to our problem: the falconers needed to come every day and ideally there would be two birds of prey chasing away the gulls. The gulls in this area are very brave. They once attacked a bird of prey causing it to fly away. We used to have the falconers do a flight for 4-5 days a week, this wasn’t consistent enough and the results were minor.”
Security issues at the terminal
“The floor and mooring posts at the terminal can be very slippery because of the humid environment combined with the bird droppings. This creates a dangerous working environment.
The workers that tie the ship to the mooring posts have to walk over the terminal while having the risk of slipping and falling off into the water.” – says Alejandro.
Alejandro explains about the maintenance problem: “The corrosive gull droppings can effect material in the pipes and eventually cause them to break.” He continues: “We constantly need to clean the terminal so that the material doesn’t wear out, this costs us a lot of time and money.”
“We have up to 8 – 9 operations every month. The pilot decides if the area is safe and clean enough to tie up at the time of docking a ship. If the terminal is too dirty and considered unsafe by the pilot he will decide not to tie up. One waiting boat costs 1,000 USD an hour since it is anchored. If the reason for not docking is due to the terminal being unsafe and dirty, all charges will have to be covered by the terminal.”
Results after Agrilaser Autonomic’s installation
Alejandro realized he needed another solution to repel gulls from the dock. After doing some research on bird deterrent methods, he found his solution to the gull problems: ”We decided to install the Agrilaser Autonomic laser bird deterrent at our dock. The laser immediately reduced bird presence and directly decreased the cleaning costs. Before installation we had to clean at least twice every month. Since installation of the Agrilaser Autonomic we only have to clean every one and a half month. This is a reduction of at least 50%!” Alejandro adds: “I was hesitant at first about using laser technology as a bird deterrent but after giving it a try and immediately seeing the results I realized it works perfectly.”
