What is the maximum elapsed time between servicing of inflatable liferafts at an approved facility?

Inflatable liferafts are critical safety equipment mandated by maritime regulations, requiring regular servicing to ensure their readiness and functionality in emergencies. The correct choice reflects the regulatory requirements that state inflatable liferafts must be serviced at an approved facility at least once every 12 months, but an allowance is provided for a maximum elapsed time of up to 15 months based on specific circumstances.

This timeframe considers operational constraints that some vessels may face, such as extended voyages or other logistical challenges. However, maintaining the liferaft in accordance with the best practices typically suggests aiming for annual servicing to guarantee optimal performance and compliance with safety standards.

The other provided options extend beyond this maximum timeframe. Liferafts serviced after 15 months could potentially compromise safety and effectiveness, thereby failing to meet regulatory expectations. Thus, ensuring maintenance within the 15-month limit is crucial for the safety of all crew members on board, making this choice the most appropriate answer.
