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 key amendments entering into force in 2020 and 2023. It works alongside Chapter II-2 (fire protection), and together these two chapters define the core safety equipment a vessel must carry to pass Port State Control.
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. Equipment must be type-approved, correctly stowed for immediate access, and maintained on a documented schedule.
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
Launching Appliances (Regulations 13–16)
Survival craft are only effective if they can be launched safely under real conditions. SOLAS requires that lifeboats and rescue boats be served by approved davits and winches capable of launching with the vessel listed up to 20° and trimmed up to 10°. Key points:
- On-load and off-load release gear must comply with the revised LSA Code (the 2014 amendments tightened release-hook design after a series of accidents).
- Lifeboat winch brakes, falls (wire ropes) and release gear must be examined annually and operationally tested.
- Rescue boats must be capable of launch and recovery within prescribed times; recovery of a single person from the water should be possible.
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.
The EPIRB's hydrostatic release unit (HRU) must be replaced on its expiry date — an overdue HRU is one of the most frequent Port State Control findings.
Fire Safety Equipment (SOLAS Chapter II-2)
Life-saving appliances are only half of a vessel's safety outfit. SOLAS Chapter II-2 governs fire protection, detection and extinction, and PSC inspectors check it as closely as Chapter III. Core requirements include:
- Portable extinguishers: Located in accommodation, machinery and service spaces. Each type (CO₂, foam, dry powder) suited to the risk in that space.
- Fixed fire-fighting systems: Machinery spaces require a fixed system — CO₂, high-expansion foam, or water mist. Engine rooms also need a fixed local application system for high-risk components.
- Fire detection and alarm: Automatic detectors and manual call points across accommodation, service and machinery spaces, with a central indicating panel on the bridge.
- Fireman's outfits: Including self-contained breathing apparatus (SCBA), fire-resistant clothing, lifeline and safety lamp — minimum two outfits, more on larger and passenger ships.
- EEBDs (Emergency Escape Breathing Devices): Provided in accommodation and machinery spaces to allow escape from a smoke-filled compartment.
- Fire pumps, hydrants, hoses and the International Shore Connection, plus posted fire control plans at access points.
Maintenance and Inspection Intervals
SOLAS Regulation III/20 and the associated maintenance guidelines (MSC.1/Circ.1432, as amended) require a documented schedule. A typical regime:
| Interval | Checks |
|---|
| Weekly | Visual inspection of all survival craft, launching appliances and EPIRB; lifeboat engine run; alarm and lighting test. |
| Monthly | LSA checklist completed and logged; lifeboat lowered to embarkation deck where practicable; flare and first-aid inventory check. |
| Annual | Liferaft servicing at an approved station; HRU and release-gear inspection; EPIRB battery and self-test; davit winch brake test. |
| 5-yearly | Lifeboat falls renewed/turned end-for-end (or earlier if required); load test of launching appliances. |
Crew Training and Drills (Regulation 19)
Equipment alone does not satisfy SOLAS — the crew must be drilled to use it. Requirements include:
- Abandon-ship and fire drills: Each crew member participates monthly; on passenger ships a muster is held before or immediately after departure.
- On-board training and instructions: A SOLAS training manual and maintenance instructions must be available in the working language of the crew.
- Drill records, including dates and equipment used, must be logged and are reviewed during PSC inspections.
Recent 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 and fire safety 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
- Discharged or out-of-date fire extinguishers and untested fixed systems
SOLAS Safety Equipment Compliance Checklist
Use this quick pre-inspection checklist before a port call:
- Lifejackets: count correct (crew + 10% + child jackets for passenger ships), lights working
- Immersion suits / liferafts: count and servicing date valid
- Pyrotechnics: in date (replace at least 12 months before expiry)
- EPIRB: registered, self-test passed, HRU and battery in date
- SART / AIS-SART: tested, batteries in date
- Lifeboat/rescue boat: engine starts, release gear and falls inspected
- Fire extinguishers, fixed systems and detectors: serviced and tagged
- Fireman's outfits and EEBDs: complete, SCBA charged
- Drill records and training manual: up to date and available
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.
Does SOLAS Chapter III apply to vessels under 500 GT?
Chapter III applies in full to vessels of 500 GT and above on international voyages. Smaller vessels and those on restricted coastal trade follow modified national requirements, but the core LSA principles still apply.
What is the difference between an EPIRB and a SART?
An EPIRB transmits a distress alert with the vessel's identity and position via satellite (406 MHz). A SART is a radar transponder that helps rescuers home in on a survival craft at close range. SOLAS vessels carry both.
How often are abandon-ship and fire drills required?
Each crew member must take part in an abandon-ship drill and a fire drill every month. Passenger ships hold a passenger muster before or shortly after departure.
What are the most common Port State Control deficiencies?
Expired pyrotechnics, overdue liferaft servicing, non-functional EPIRBs and discharged fire extinguishers top the list. Most are avoidable with a disciplined maintenance schedule.
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.
