- Amendments: SOLAS is regularly updated and amended to keep pace with technological advancements and address new safety challenges.
- Implementation and enforcement: SOLAS is implemented and enforced by flag states (the countries where ships are registered) and port states (countries where ships visit).
Main objectives of SOLAS:
- Protect human life at sea: The primary goal of SOLAS is to ensure the safety of passengers and crew on board ships.
- Enhance maritime safety: SOLAS establishes minimum safety standards for ships to prevent accidents and incidents at sea.
- Protect the marine environment: SOLAS includes provisions to prevent pollution from ships and minimize the impact of maritime activities on the environment.
Some of the key provisions of SOLAS include:
- Ship construction: SOLAS sets standards for the design, construction, and maintenance of ships to ensure they are seaworthy and structurally sound.
- Fire protection: SOLAS requires ships to have adequate fire detection and firefighting systems to prevent and control fires on board.
- Lifesaving appliances: SOLAS mandates that ships carry sufficient lifesaving equipment, such as lifeboats, life rafts, and personal flotation devices, to ensure the survival of passengers and crew in case of an emergency.
- Radio communication: SOLAS requires ships to be equipped with radio communication systems to enable them to communicate with other ships and shore stations for safety and distress purposes.
- Navigation: SOLAS sets standards for navigational equipment and procedures to ensure safe navigation and prevent collisions at sea.
- Carriage of dangerous goods: SOLAS regulates the transport of dangerous goods on ships to minimize the risk of accidents and environmental pollution.
- Safety management: SOLAS requires ships to have a Safety Management System (SMS) in place to ensure that safety procedures are followed and that safety risks are managed effectively.
In conclusion, SOLAS is a vital instrument in promoting maritime safety and protecting human life at sea. It sets minimum safety standards for ships, ensures that they are equipped with necessary safety equipment, and promotes safe practices and procedures on board.

Chapter V, Regulation 26 – Steering gear: testing and drills
- Testing before departure:
- Within 12 hours before departure, the ship’s steering gear must be thoroughly checked and tested by the ship’s crew. 1. Guidance with respect to Questionnaire for 2019 CIC on Emergency Systems and Procedures. – Irclass.org www.irclass.org
- The test procedure includes the operation of the main steering gear, auxiliary steering gear, remote steering gear control systems, steering positions on the navigation bridge, emergency power supply, rudder angle indicators, and power failure alarms.
- The checks and tests include full movement of the rudder, visual inspection of the steering gear and its linkage, and operation of communication between the bridge and steering gear compartment. 1. SOLAS V and Steering Gear – Navsregs navsregs.wordpress.com
- Additional weekly testing:
- For tankers, chemical tankers, or gas carriers of 10,000 gross tonnage and upward, these checks and tests must be conducted at least once a week even if there is no departure.
- Emergency steering drills:
- Emergency steering drills, to practice using the auxiliary or emergency steering gear in case of main steering gear failure, must be conducted at least once every three months. 1. SOLAS V and Steering Gear – Navsregs navsregs.wordpress.com
- Record keeping:
- The dates of all checks, tests, and drills, along with their details, must be recorded in the ship’s logbook. 1. SOLAS V and Steering Gear – Navsregs navsregs.wordpress.com
These requirements aim to ensure that the steering gear is in good working order, that the crew is familiar with its operation and emergency procedures, and that any potential issues are identified and addressed before they can cause an accident.
Requirements for the routine testing of steering gears prior to sailing from port
According to SOLAS (Safety of Life at Sea) regulations, the following routine tests are required for steering gears prior to sailing from port:
- Comprehensive Check and Test: The ship’s steering gear must undergo a thorough check and test within 12 hours before departure. This is to ensure it’s in optimal working condition and any potential issues are identified and addressed before sailing.
- Components Included in the Test: The test encompasses several key components of the steering system, including:
- Main steering gear: The primary system used to control the rudder.
- Auxiliary steering gear: A backup system that can be used in case of main steering gear failure.
- Remote steering gear control systems: Systems allowing control of the steering gear from locations other than the main bridge.
- Steering positions on the navigation bridge: The primary control stations for the steering gear.
- Emergency power supply: The backup power source for the steering gear in case of main power failure.
- Rudder angle indicators: Instruments that show the current position of the rudder.
- Power failure alarms: Alarms that sound in case of a power loss to the steering gear.
- Elements of the Test: The checks and tests include:
- Full movement of the rudder: Ensuring the rudder can move through its full range of motion.
- Visual inspection: A physical check of the steering gear and its connecting parts for any signs of wear, damage, or leaks.
- Communication check: Verifying that communication between the bridge and steering gear compartment is functional.
- Frequency for Certain Vessels: For tankers, chemical tankers, or gas carriers of 10,000 gross tonnage and upward, these checks and tests must be conducted at least once a week, even if there’s no planned departure.
- Record Keeping: It’s mandatory to document the dates of all checks, tests, and their details in the ship’s logbook. This record helps maintain a history of maintenance and ensures compliance with regulations.
These stringent requirements underscore the critical importance of a well-functioning steering gear for safe navigation and maneuverability at sea. By mandating routine testing prior to departure, SOLAS aims to minimize the risk of steering-related accidents and ensure the safety of the vessel, crew, and passengers.
Testing of steering gears at three monthly intervals while the vessel is proceeding on passage
SOLAS, specifically Chapter V, Regulation 26, mandates the following requirement for routine testing of steering gears at three-month intervals while a vessel is on passage:
- Emergency Steering Drills: The regulation states that emergency steering drills must be carried out at least once every three months.
The primary purpose of these drills is to ensure the crew’s proficiency in handling the auxiliary or emergency steering gear in case of a failure of the main steering gear. This is vital to maintain the vessel’s maneuverability and avoid potential accidents in critical situations.
While the regulation doesn’t explicitly outline the specific procedures for these drills, they should encompass the following:
- Simulation of Main Steering Gear Failure: The drill should realistically simulate a scenario where the main steering gear becomes inoperable.
- Activation and Operation of Backup Systems: The crew should practice switching to the auxiliary or emergency steering gear and demonstrate their ability to control the vessel using these backup systems.
- Communication and Coordination: The drill should also involve effective communication and coordination between the bridge team and the personnel responsible for operating the backup steering gear.
It’s essential to note that these drills are in addition to the routine checks and tests that must be performed within 12 hours before departure from any port, as outlined in the same regulation.
By mandating regular emergency steering drills, SOLAS ensures that the crew remains prepared to handle potential steering gear failures, even while the vessel is underway. This proactive approach contributes significantly to enhancing safety at sea and minimizing the risk of accidents due to loss of steering control.
