IMO: Lifeboat maintenance and inspection amendments

The International Maritime Organization has issued resolution MSC.559(108) amending the requirements for the maintenance, thorough examination, operational testing, overhaul, and repair of lifeboats, rescue boats, launching appliances, and release gear.

The amendments aim to keep safety protocols current, particularly concerning ventilation systems for totally enclosed lifeboats. This is in response to advancements in safety practices and lessons learned from past incidents.

The resolution recalls previous decisions, notably Resolution MSC.402(96), which set forth the initial requirements for the maintenance and examination of lifesaving equipment. The amendments align with updates made in Resolution MSC.535(107) regarding ventilation.

Specific Amendments to Requirements

The amendments include detailed procedures for annual inspections and operational tests. Key aspects of the new inspection protocols for lifeboats and rescue boats include:

Structural Examination: Inspecting the boat structure, including both fixed and loose equipment, and conducting visual checks of void spaces where possible.
Engine and Propulsion System: Assessing the condition and functionality of the engine and propulsion systems to ensure safe operation.
Safety Systems: Checking installed systems such as sprinklers, air supply, and maneuvering systems to confirm they are operational.
Power Supply: Evaluating the power supply systems to ensure reliability in emergency situations.
Bailing and Fender Systems: Inspecting the bailing systems and fender/skate arrangements for effective water management and stability.
Righting System: For rescue boats, ensuring that the righting systems are functioning correctly, which is vital for crew safety.
Ventilation System: Assessing ventilation systems to ensure they are in good working order, particularly for enclosed lifeboats.

The amendments will come into force on January 1, 2026.
