Overview of SOLAS Chapter III
SOLAS (Safety of Life at Sea) Chapter III, "Life-Saving Appliances and Arrangements," sets minimum safety standards for all commercial vessels engaged on international voyages. The chapter was significantly revised in 1983 and updated multiple times since, with the most recent key amendments entering into force in 2020 and 2023.
Chapter III applies to vessels of 500 GT and above on international voyages, with modified requirements for smaller vessels and those on restricted coastal trade.
Key Equipment Categories Under SOLAS Chapter III
Regulation 7: Personal Life-Saving Appliances
- Lifejackets: SOLAS-compliant, one per person plus 10% reserve. Type I (offshore) or Type II (nearshore). Must be stowed for immediate access.
- Immersion Suits: One per person for vessels in cold waters. Donning time maximum 2 minutes.
- Lifebuoys: Based on ship length — 8 required for vessels 100–150m; up to 12 for vessels over 300m. 50% must carry self-igniting lights. At least 2 must be equipped with self-activating smoke signals.
Regulation 17–20: Survival Craft
- Cargo Ships: Minimum one totally enclosed lifeboat capable of carrying all persons on board, plus liferafts with a total capacity of 100% of persons on each side. Alternatively, two totally enclosed lifeboats — one on each side.
- Passenger Ships: Liferaft capacity for 25% of persons on each side, with lifeboat capacity for 100% total.
- Free-fall Lifeboats: Permitted alternative for certain cargo ship types, especially bulk carriers and tankers.
Regulation 32–33: Distress Signals
- 12 parachute rocket flares (SOLAS approved)
- 6 hand flares per lifeboat/liferaft
- 2 buoyant smoke signals per rescue boat
- Expiry date must be within 3 years from manufacture, replace annually in high-risk regions
EPIRB and SART Requirements
Since 1999, all SOLAS vessels are required to carry:
- One 406 MHz float-free EPIRB, registered with national authority (MMSI and vessel details). Must be tested annually; replace battery per manufacturer schedule (typically every 5 years).
- Two Search and Rescue Transponders (SART) or equivalent AIS-SARTs — one for each survival craft on each side of the vessel.
2023–2025 SOLAS Amendments to Note
- Updated hydrostatic release unit (HRU) performance standards (MSC.1/Circ.1612)
- Revised liferaft servicing intervals for certain compact units
- New requirements for MOB (Man Overboard) systems on passenger vessels
- Updated EPIRB registration database requirements
Port State Control and Non-Compliance Consequences
PSC inspectors focus heavily on LSA during port calls. The most common deficiencies leading to detention include:
- Expired pyrotechnics (most common — replace at least 12 months before expiry)
- Overdue liferaft servicing
- Non-functional EPIRB (failed hydrostatic release test or dead battery)
- Insufficient number of lifejackets (including child lifejackets for passenger vessels)
- Blocked access to survival craft
Frequently Asked Questions
How often must liferafts be serviced under SOLAS?
Annually at an approved service station. The service due date is stamped on the liferaft container and must not be exceeded. Some compact liferafts qualify for 30-month service intervals — verify with the manufacturer.
Where can I purchase SOLAS-compliant safety equipment?
Only purchase from suppliers holding MED (Marine Equipment Directive in EU) or equivalent approval certificates. E-ShipSupply lists verified suppliers who provide product-level certificates with every order.
