What must be done if current exceeds 1 knot during a diving operation?

When the current exceeds 1 knot during a diving operation, conducting an Operational Risk Management (ORM) analysis is essential. This analysis helps to evaluate the potential hazards and assess the risks involved with continuing the dive under such conditions. Strong currents can pose significant dangers to divers, including difficulties in maintaining position, challenges in returning to the ascent line or support vessel, and an increased risk of physical exhaustion or entrapment.

Performing ORM allows dive supervisors to analyze the situation thoroughly, considering both environmental factors and the divers' capabilities. Based on this assessment, an informed decision can be made regarding whether to continue the operation, modify dive plans, or potentially abort the dive for safety reasons. It's a structured approach that prioritizes the safety of the divers while ensuring that all necessary precautions are taken in response to potentially hazardous conditions.
