The International Convention for the Safety of Life at Sea (SOLAS) introduced significant amendments on January 1, 2024, marking the most comprehensive maritime safety update in years. Ship officers must understand these changes to maintain compliance and ensure crew safety. The amendments affect mooring operations, emergency communications, watertight integrity, and life-saving equipment with some applying retroactively to all vessels and others only to new construction.
SOLAS 2024 Amendments: Core Changes Explained
January 1, 2024 marked a pivotal date for maritime safety regulation. The IMO implemented amendments affecting all vessels globally, with compliance deadlines extending through 2026. Understanding which amendments apply to your vessel based on construction date, tonnage, and vessel type is essential for audit readiness.
Key principle: Some amendments apply retroactively to all existing ships. Others affect only new construction. Knowing the difference prevents compliance gaps.
Maritime Safety Updates: Mooring Equipment Requirements
Mooring-related accidents account for significant maritime injuries annually. The 2024 amendments strengthen mooring safety standards with comprehensive requirements for selection, arrangement, inspection, maintenance, and replacement of mooring equipment.
New construction (3,000 GT+, constructed on/after January 1, 2024):
-
Enhanced design requirements must be met
-
Documentation on mooring arrangements and equipment selection required onboard at all times
-
Towing and Mooring Arrangement Plan must include ship-specific information
Existing vessels (all sizes, all construction dates):
-
Inspection and maintenance requirements apply retroactively
-
Mooring equipment must be inspected per manufacturer specifications
-
Documentation must reflect compliance with new standards
-
Risk assessment required for all mooring operations
Practical implication: Existing vessels cannot ignore these requirements. PSC inspectors verify mooring inspection records during port state control visits.
Ship Safety Regulations: GMDSS Modernization
The Global Maritime Distress and Safety System received a comprehensive modernization reflecting current communication technologies. These amendments remove obsolete system requirements while enabling future technologies a critical update for vessels carrying radio equipment.
Major changes:
-
Communication equipment reclassification: GMDSS requirements moved from SOLAS Chapter III (life-saving appliances) to Chapter IV (radio communications), clarifying equipment jurisdiction.
-
Sea area definitions updated: Sea Areas A1-A4 now reflect varying coverage between satellite service providers (Inmarsat, Iridium, etc.), acknowledging technology diversity.
-
Mandatory position inclusion: Two-way distress alerting radios must automatically include the ship's position in distress alerts, enhancing rescue response.
-
Provider-neutral requirements: New generic requirements independent of specific satellite service providers allow future technology integration without regulatory overhaul.
-
Vessels affected: All ships of 300 GT and above must ensure communication equipment meets updated Chapter IV requirements. Officers should review equipment against new standards immediately.
International Maritime Law: Enhanced Safety Standards
Watertight Integrity & Damage Stability
SOLAS Chapter II-1 amendments align watertight integrity with probabilistic damage stability approaches. These changes enhance vessel safety when damaged by addressing flooding scenarios and watertight door placement standards.
What changed: Harmonized watertight door requirements across SOLAS, MARPOL Annex I, Load Lines Convention, IBC Code, and IGC Code. Previous inconsistencies regarding door types (sliding vs hinged), technical requirements, and operational frequencies have been resolved.
Who is affected: Only new cargo and passenger ships constructed on or after January 1, 2024. Existing vessels unaffected by these design amendments.
Fire Detection System Simplification
Fire detection system requirements have been simplified without compromising safety. Short circuit isolators are no longer required at each individual fire detector for cargo ships and passenger ship balconies.
Benefit: Reduces installation and maintenance burden while maintaining effective fire detection. Officers should verify fire detection system documentation reflects current requirements.
Life-Saving Appliances Updates
The Life-Saving Appliances (LSA) Code was revised to remove outdated requirements inconsistent with modern lifeboat technology:
-
Buoyant oars eliminated: No longer required in lifeboats with two independent propulsion systems
-
Free-fall lifeboat headway requirement removed: Cargo ships of 20,000 GT+ no longer required to launch free-fall lifeboats with ship making 5-knot headway
These changes acknowledge technological advances while maintaining crew safety during emergencies.
Maritime Safety Updates: Alternative Fuel Vessels
The International Code for Ships Using Gases or Low-flashpoint Fuels (IGF Code) received substantive amendments reflecting lessons learned since 2017 implementation. Changes focus on fire protection, safe fuel distribution, and containment systems.
Scope: Ships constructed on or after January 1, 2024, using LNG or low-flashpoint fuels must comply with updated IGF Code requirements.
Why it matters: As the maritime industry transitions to cleaner fuels (LNG, methanol, hydrogen, ammonia), understanding IGF Code provisions is essential. Officers on vessels considering alternative propulsion must understand new safety requirements.
Ship Safety Regulations: IP Code & 2026 Deadlines
The International Code for Safety for Ships Carrying Industrial Personnel (IP Code) entered into force July 1, 2024, through SOLAS Chapter XV. This code provides safety requirements for vessels carrying personnel engaged in offshore industrial activities (wind farm installation, oil platform construction, etc.).
Compliance deadline: Existing vessels must comply by January 1, 2026.
Additional 2026 amendments taking effect:
-
Mandatory flashpoint declarations: Oil fuel suppliers must declare flashpoint before bunkering (effective 2026)
-
PFOS prohibition: Fire extinguishing media containing perfluorooctane sulfonic acid (PFOS) prohibited after first survey on/after January 1, 2026
International Maritime Law: Future Developments
The IMO is developing regulatory frameworks for autonomous ships and additional fuel types. Expected updates include provisions for methanol, LPG, hydrogen, and ammonia fuel systems, with implementation timelines likely in 2025-2026.
These forward-looking regulations position the maritime industry for technology evolution while maintaining safety standards established through SOLAS history.
Achieving SOLAS 2024 Compliance
For existing vessels:
-
Verify mooring equipment inspection records meet new standards
-
Review GMDSS communication equipment against Chapter IV requirements
-
Confirm two-way distress radio position transmission capability
-
Document compliance status for PSC inspections
-
Plan for 2026 compliance deadlines (IP Code, PFOS prohibition)
For new construction: Meet all design requirements for mooring equipment, watertight integrity, GMDSS systems, and fuel type-specific codes (IGF for gas-fueled vessels).
For all vessels: Obtain the latest SOLAS consolidated edition incorporating 2024 amendments. Current publications ensure accurate compliance guidance and regulatory references for crew training and PSC preparation.
American Nautical Services, as an authorized IMO publication distributor, provides current SOLAS consolidated editions with all 2024 amendments included. Access to authoritative regulations is essential for compliance documentation and crew understanding.
