The rated capacity of lifeboats is a core safety component for all vessels, which directly guarantees the survival safety of crew and passengers during emergency abandonment. In accordance with the latest SOLAS amendments, all lifeboats shall be designed and rated based on unified weight standards and meet mandatory configuration requirements for different ship types.
Compliant marine lifeboat capacity ensures safe evacuation under severe weather and rough sea conditions, fully satisfies classification society audits and maritime inspections, and avoids non-compliance penalties. Certified lifeboats provide reliable buoyancy, fully enclosed protection and essential survival support in extreme marine environments, improving the overall emergency response capability of vessels.
Passenger ships, cargo vessels, offshore support vessels, workboats and research vessels differ greatly in crew capacity and operating conditions. Thus, the required quantity, rated capacity and structural type of lifeboats are regulated separately to match operational demands.
SOLAS sets unified global standards for lifeboat design, capacity calculation and structural performance:
Standard weight calculation: 82.5kg per person;
Totally enclosed lifeboats are mandatory for ocean-going vessels with full type approval;
All lifeboats must complete load tests, tightness inspection and harsh environment verification with valid classification society certification.
Ships shall register the maximum number of crew members and passengers. The total rated capacity of lifeboats must fully cover the maximum onboard personnel. Ship owners shall update personnel data regularly to prevent overloading and capacity shortage.
Vessels operating in cold water, polar regions and rough sea areas must be equipped with totally enclosed lifeboats for better cold resistance, windproof and wave resistance. Coastal vessels can adopt matched life-saving equipment within regulatory limits.

Passenger ships require the highest safety redundancy. Lifeboats shall be symmetrically arranged on both sides, with sufficient total capacity for full personnel evacuation, cooperating with life rafts and rescue boats to form a complete safety system.
Recommendations:
Verify passenger and crew numbers before each voyage;
Keep embarkation access clear and conduct regular emergency drills;
Maintain lifeboat sealing, power system and emergency supplies regularly.
Ocean-going cargo ships are mandatory to install totally enclosed lifeboats to protect crews during long-distance navigation. Lifeboats on both sides shall be fully equipped to cover all crew members and ensure backup availability in case of single-side equipment failure.
Recommendations:
Adopt fully enclosed lifeboats for open sea navigation;
Select matched size and launching system according to ship layout;
Implement monthly inspection and maintenance for stable performance.
Offshore support vessels, workboats and marine research vessels need customized lifeboats based on crew size, operating waters and installation conditions. Offshore platform vessels require heavy-duty, corrosion-resistant and high-sea condition resistant lifeboats.
Recommendations:
Customize selection according to operational characteristics;
Prioritize durability, corrosion resistance and rapid launching performance;
Comply with special industry rules and local maritime requirements.

1. What determines the official rated capacity of a lifeboat?
The rated capacity is certified by classification societies, calculated based on internal space, buoyancy and structural load. The approved capacity shall be clearly marked on each lifeboat.
2. How to calculate the total required lifeboat capacity?
Calculate the maximum number of crew and passengers on board. The total capacity of all lifeboats shall meet the minimum SOLAS requirements with reasonable safety redundancy.
3. Is capacity marking mandatory?
Yes. Permanent and clear capacity marking is legally required and will be inspected during port state control and class surveys.
4. What is the standard frequency of abandon-ship drills?
All international vessels shall conduct abandon-ship drills at least once a month. Passenger ships shall strengthen pre-voyage drills and keep complete records.
