Every SOLAS‑certified vessel must carry and maintain a set of lifesaving appliances that protect people from the moment an emergency begins until rescue is complete. This article gives vessel owners, managers, and HSE teams a clear, practical overview of the essential equipment required under SOLAS and the LSA Code, and what it takes to keep that equipment compliant and ready.
SOLAS and the LSA Code
SOLAS Chapter III and the International Life‑Saving Appliance (LSA) Code define what lifesaving appliances ships must carry, how they must be designed and tested, and how they are to be maintained throughout the vessel’s life. Rather than reproducing regulatory text, this article translates those requirements into practical categories and maintenance expectations that can guide onboard safety management.
Main lifesaving appliance categories
Under SOLAS and the LSA Code, lifesaving appliances fall into several broad groups. For any vessel in international service, the safety management system should clearly address:
- Personal lifesaving appliances: lifebuoys, lifejackets, immersion suits, anti‑exposure suits, and thermal protective aids.
- Survival craft and rescue boats: lifeboats, liferafts, and rescue boats with their associated equipment.
- Visual distress signals and line‑throwing appliances: rockets, flares, smoke signals, and line‑throwing gear.
- Launching, embarkation, and evacuation systems: davits, winches, release gear, ladders, and marine evacuation systems.
- Alarms and communication: general alarm, public address, and on‑scene communication equipment.
Each category plays a specific role in prevention, abandonment, survival, and rescue, so gaps in any one area can compromise the entire emergency response chain.
Personal lifesaving appliances
Personal lifesaving appliances are the first line of protection when something goes wrong at sea. SOLAS and the LSA Code set detailed requirements for their performance, stowage, and availability.
- Lifebuoys must be distributed along open decks, fitted with lines, self‑igniting lights, and smoke signals as required, and stowed in quick‑release brackets for immediate deployment in man‑overboard situations.
- Lifejackets must provide sufficient buoyancy, self‑righting capability, and head support, and be correctly sized and readily accessible at muster and cabin locations, with lights and whistles as specified.
- Immersion suits and anti‑exposure suits offer thermal protection in cold or rough waters and must be maintained free from tears, with functioning zippers and seals, and stored where crews can don them quickly.
- Thermal protective aids provide additional insulation in survival craft, especially on cold routes, and should be included and maintained as per equipment lists.
Regular checks should verify numbers, condition, markings, and stowage, and drills must ensure crew can don equipment within required times.
Survival craft and rescue boats
Survival craft and rescue boats provide the means to abandon ship and remain safe until rescue, and SOLAS requires sufficient capacity for everyone on board, with redundancy depending on ship type. The LSA Code specifies design, equipment, and performance standards for these craft.
- Lifeboats (including totally enclosed and free‑fall types) must meet capacity, protection, propulsion, and equipment requirements, and be arranged for safe embarkation and launching in adverse conditions.
- Liferafts must comply with standards on capacity, construction, canopies, righting, and emergency equipment packs, and are often arranged in both davit‑launched and float‑free configurations.
- Rescue boats are dedicated craft for recovering persons from the water and for assisting liferafts, with quick launching and recovery, adequate maneuverability, and essential equipment.
Maintenance regimes include weekly and monthly inspections, periodic servicing of inflatable equipment at approved stations, and regular abandon‑ship and man‑overboard drills using lifeboats and rescue boats.
Visual distress signals and line‑throwing appliances
Visual distress signals and line‑throwing appliances are critical for attracting attention and establishing contact once a vessel or survival craft is in distress.
- Parachute rockets, hand flares, and buoyant smoke signals are required in defined quantities and must meet performance standards for visibility, burn time, and reliability.
- Line‑throwing appliances provide a means of passing a messenger line to a person, survival craft, or another ship to establish a stronger connection for rescue.
Practical maintenance focuses on monitoring expiry dates, storing pyrotechnics in dry, secure locations, inspecting for damage, and ensuring crew are trained to use them safely and in the correct sequence.
Launching, embarkation, and evacuation systems
Launching and embarkation systems make the transition from ship to survival craft as safe and controlled as possible. SOLAS and the LSA Code define requirements for safe, reliable operation of these systems even when the ship is damaged or listing.
- Davits, winches, and release hooks must be designed and maintained so that survival craft and rescue boats can be launched quickly and safely with their full complement.
- Marine evacuation systems, where fitted, provide rapid, controlled evacuation down slides or chutes into liferafts and must be inspected, tested, and deployed in drills according to manufacturer instructions.
- Embarkation ladders, lighting, and communications between bridge and embarkation stations form part of the overall abandonment arrangement and must remain in good working order.
Typical requirements include frequent onboard checks, annual thorough examinations, and five‑yearly proof load tests of launching appliances and release gear, with detailed records retained for class and flag.
Alarms, PA, and communication
Effective alarms and communication systems ensure that crew and passengers receive timely, understandable instructions during emergencies. SOLAS prescribes:
- A general alarm system capable of being heard or seen in all normally occupied spaces, to indicate that an emergency has arisen.
- A public address system on passenger ships and many cargo ships, to broadcast clear, intelligible safety announcements and mustering instructions.
- Portable radios and other on‑scene communication devices used by emergency teams during fire fighting and abandon‑ship operations.
Regular testing of alarms, PA audibility checks, and battery condition checks on portable equipment are essential parts of the ship’s planned maintenance system
Maintenance, testing, and records
Lifesaving appliances only deliver their intended protection when they are fully functional, properly stowed, and supported by trained personnel. SOLAS and the LSA Code set out a structured maintenance regime that typically includes:
- Routine inspections: weekly and monthly checks of lifeboats, rescue boats, liferafts, lifejackets, lifebuoys, and launching gear, with defects rectified promptly.
- Periodic servicing: annual and multi‑year servicing of liferafts, lifejackets, and other inflatable appliances at approved service stations, as well as periodic overhauls of release gear and launching appliances.
- Drills and training: regular abandon‑ship and man‑overboard drills to maintain crew proficiency and to verify that equipment, communications, and procedures work together as intended.
- Documentation and records: up‑to‑date maintenance logs, drill records, defect reports, and service certificates ready for flag State, port State, and classification society inspections.
Many administrations and classification societies provide consolidated guidance on maintenance of lifesaving appliances that can be integrated into the vessel’s planned maintenance system.
Practical compliance tips and common gaps
In practice, non‑conformities often arise not from missing equipment but from lapses in upkeep, documentation, or familiarization. To strengthen compliance:
- Use standardized checklists that mirror SOLAS/LSA categories and manufacturer instructions to ensure all items are inspected at the correct intervals.
- Track expiry dates for pyrotechnics, emergency rations, water, and batteries in survival craft packs, and schedule replacements well before due dates.
- Review lifejacket and immersion suit inventories whenever manning levels, trading areas, or operating profiles change to maintain correct quantities and sizes.
- Consider pre‑inspection audits by competent service providers before dry dockings, class renewals, or expected port State control focus campaigns.
Building these practices into routine operations reduces the risk of last‑minute rectifications and improves overall safety culture on board.
How MarineCraft can support vessel operators
