Torpedo Battery Facility Survey on Mali Brijun Island (UAV, ROV)

Brijuni National Park is a place of great cultural and historical significance, but its coastal location means that the cultural assets in the park are increasingly exposed to severe weather conditions, leading to deterioration and even destruction of buildings.

The torpedo battery on the island of Mali Brijun is a prime example of a historical site that has been severely affected by storms.

To prevent further damage, a team of experts from the Faculty of Civil Engineering at the University of Rijeka carried out a non-invasive visual assessment of the building using visible and invisible light spectrum methods.

The assessment served as a basis for the preparation of a conservation study, architectural survey, and conceptual, main, and detailed designs for rehabilitation work.

Torpedo Battery Facility Survey as a Basis for Future Interventions

Following a strong storm in February 2016 and 2017, the embankment of the torpedo battery was severely damaged and required urgent intervention to protect the building from further deterioration.

As part of the rehabilitation process, a comprehensive terrestrial, aerial photogrammetry, laser, and underwater survey of the facility was conducted to assess the damage and accurately document the condition of the building.

The data collected included:

  • a laser 3D scan,
  • terrestrial 360-degree images,
  • aerial photogrammetric SFM images,
  • continuous photographs of four individual parts of the facades,
  • vertical transects of coastal walls, and underwater footage video with timecode,
  • providing a detailed record of the building’s condition.

This data collection approach will allow the Client to monitor the building over time and detect any changes or damage.

The documentation resulting from these measurements will serve as a basis for future interventions at the facility, ensuring quality and proper planning.

The comprehensive approach to data collection will also help preserve historical sites and protect them from further damage caused by severe weather conditions.

In conclusion, preserving cultural and historical sites is crucial, and protecting them from severe weather conditions requires a proactive approach.

The non-invasive visual assessment and comprehensive data collection approach used in the rehabilitation of the torpedo battery in Brijuni National Park can serve as a model for future efforts to protect other historical sites from the effects of climate change.
