What's Happening?
The International Marine Contractors Association (IMCA) has issued a reminder to vessel owners and operators about the significant risks associated with underwater ship husbandry (UWSH) operations, especially as activity in the Strait of Hormuz increases.
With vessels returning to service after extended periods at anchor, there is a sharp rise in demand for hull cleaning, inspection, and maintenance. These activities are crucial for restoring vessel efficiency by removing marine growth and biofouling. However, UWSH remains one of the most hazardous areas of commercial diving, with multiple fatalities reported in recent years due to unqualified dive teams and inappropriate equipment. IMCA has launched a campaign to raise awareness of UWSH safety challenges and published guidance to improve safety standards.
Why It's Important?
The increase in vessel maintenance demands highlights the broader implications for the maritime industry, particularly in terms of safety and environmental impact. The accumulation of marine growth on idle vessels can significantly reduce fuel efficiency and pose ecological risks by transferring invasive species. The high fatality rates in UWSH operations underscore the need for stringent safety measures and competent personnel. This situation affects not only the shipping industry but also environmental conservation efforts. Ensuring safe and efficient vessel operations is crucial for maintaining global trade routes and protecting marine ecosystems.
What's Next?
As shipping activity resumes, the industry is expected to adopt a more proactive approach to safety. IMCA's guidance on UWSH operations is likely to become a standard reference for vessel owners and operators. The focus will be on selecting competent contractors, using appropriate equipment, and ensuring proper management and supervision of diving operations. The maritime industry may also see increased collaboration with environmental agencies to address the ecological impacts of marine growth and biofouling.
