Recovery of the Bayesian: A Complex Salvage Operation

The hull of the 183ft (56m) Perini Navi superyacht Bayesian, which tragically sank off the coast of Sicily, has been successfully raised from the seabed. This significant milestone in the salvage operation comes after the vessel capsized during a sudden storm, resulting in the heartbreaking loss of seven lives, including the yacht’s owner and his daughter.

The Incident

On August 19, 2024, the Bayesian was anchored off the northern coast of Sicily when it was struck by a violent storm. The yacht sank rapidly, leading to the tragic deaths of seven individuals. The incident shocked the maritime community and raised questions about safety protocols for yachts in adverse weather conditions.

Salvage Operation Overview

The recovery of the Bayesian has been a complex and challenging endeavor, requiring specialized expertise and equipment. TMC Marine, a British salvage company, has been at the forefront of this operation. After weeks of meticulous preparation, the hull was gradually brought to the surface over a three-day period, culminating in its successful raising on June 20, 2024.

Technical Challenges

The salvage operation involved parbuckling the hull into an upright position, allowing access to the previously submerged starboard side. This intricate process required the use of eight steel lifting straps, strategically placed under the bow and stern sections of the yacht. The lifting apparatus was connected to the Hebo Lift 10, one of Europe’s largest marine cranes, which played a crucial role in the operation.

Live Coverage and Public Interest

The lifting of the Bayesian has garnered significant media attention, with local and specialized channels live-streaming the salvage efforts. The operation has not only captivated the public but also highlighted the complexities involved in maritime salvage operations.

Next Steps for the Hull

Following its initial lifting, the hull will remain in position until it is fully raised from the water. Sea water will be pumped out as the vessel is lifted, and it is expected to be transported to the Sicilian port of Termini Imerese. Once there, the hull will be placed onto a specially manufactured steel cradle, scheduled for Monday, June 23.

The Team Behind the Recovery

The salvage operation has involved a dedicated team of around 70 specialists, including experts from the Dutch crane company HEBO and SMIT Salvage, along with support from Italian professionals. The operation has also utilized remote-controlled tools, particularly after the tragic death of a salvage diver in May, which necessitated a temporary halt in operations.

Equipment and Techniques

In addition to the Hebo Lift 10, a second vessel, the Hebo Lift 2, has been deployed to assist with the operation. This multi-purpose barge features 700 square meters of deck space and an integrated crane, further enhancing the capabilities of the salvage team. Remote-controlled submersibles have been employed to recover various components of the yacht, including the mainsail and anchor chains.

Environmental Considerations

Throughout the salvage process, the recovery team has been vigilant about monitoring for pollution. A precautionary oil boom has been deployed around the site to mitigate any potential environmental impact from the wreck.

Ongoing Investigations

The sinking of the Bayesian is currently under investigation by Italian authorities, with the UK’s Marine Accident Investigation Branch (MAIB) also conducting a review. The interim report has highlighted the tragic nature of the incident, emphasizing the need for improved safety measures in the yachting industry.

Conclusion

The raising of the Bayesian marks a significant achievement in a challenging salvage operation, reflecting the dedication and expertise of the teams involved. As the investigation continues, the maritime community remains focused on understanding the factors that led to this tragic event, ensuring that lessons are learned to prevent future incidents. The recovery of the yacht not only serves as a testament to the resilience of the salvage teams but also as a somber reminder of the fragility of life at sea.
