The recent successful rescue of a Spanish diver who went missing during a dive on 20 November serves as a powerful reminder of the importance of preparation, swift action, and collaboration in ensuring diver safety.

The rescue operation

When the diver failed to surface with her group, her vessel raised the alert promptly, enabling NSRI Shelly Beach and Port Edward crews to act quickly. Despite rough sea conditions, a coordinated effort involving NSRI rescue craft, private fishing vessels, and a Transnet National Ports Authority helicopter commenced. After being adrift for over three hours, the diver was spotted waving her arms 9 nautical miles from her dive location. She was safely rescued by the NSRI’s Spirit of Dawn and reunited with her group, uninjured.

Insights into safety protocols

An NSRI operations manager and expert diver, Brett Ayres, explains that adequate diver safety begins long before an incident occurs. Early awareness is crucial. In this case, the vessel’s quick action in notifying Shelly Beach control and the NSRI’s ability to deploy resources promptly were instrumental in reducing the search area and time.

Key to the success of such operations is a combination of real-time data collection, sophisticated search programmes, and collaboration among stations. For example:

Drift Tests and Forecasting: The NSRI uses on-site drift tests combined with online forecast data to determine the likely path of a lost diver. Volunteers Marilyn Wells and Marc de Vos have developed advanced search programmes that predict a diver’s location, allowing rescuers to focus on high-probability areas.

Search Patterns: Techniques like sector and parallel line searches ensure thorough coverage of potential drift zones.

Coordination: Stations like Shelly Beach and Port Edward work together, with resources strategically positioned to maximise efficiency.

Challenges faced and lessons learned

The operation highlighted significant challenges, including rough seas that hampered visibility and search efficiency. However, the TNPA helicopter’s aerial perspective proved invaluable in spotting the diver. Ayres notes that accurate, science-based data – such as drift test results – must take precedence over anecdotal observations to avoid misdirected efforts.

Prevention is key

While rescue operations are critical, prevention remains the cornerstone of diver safety. Graeme Harding, a diving expert, stresses the importance of proactive measures:

Comprehensive safety briefings: Divemasters and skippers must ensure all participants understand dive plans, current conditions, and emergency procedures.

Use of surface marker buoys (SMBs): These devices make divers more visible to both boats and aircraft.

Adhering to buddy systems: Divers should never separate from their group, and divemasters must monitor weaker divers closely.

Staying within capabilities: Divers should avoid conditions or depths beyond their experience level.

A call for collective responsibility

The success of this rescue underscores the importance of training, preparation, and teamwork. The NSRI’s collaboration with organisations like Divers Alert Network (DAN) fosters a culture of safety and awareness within the diving community.

By prioritising prevention, maintaining clear communication, and leveraging advanced rescue techniques, both divers and professionals can contribute to safer diving experiences. As Ayres aptly puts it: “Diver safety isn’t just about reacting to incidents; it’s about preventing them. Together, we can ensure every dive is both safe and enjoyable.”
