- Over reliance on auto-pilot and poor comprehension of its efficiency and limitation has resulted in several accidents at sea.
- The use of auto-pilot is not recommended when navigating in areas with high traffic density, narrow channels and traffic separation schemes and other restricted waters. The auto-pilot may not be efficient enough to turn the vessel spontaneously while navigating in such areas demanding swift alterations and manoeuvres to avoid collision or close quarter situations.
- United States Coast Guard has issued a Marine Safety Alert 10-16 (copy attached) which addresses the safe navigation of vessels while operating with an auto-pilot.
- The Code of Federal Regulations, 46 CFR contains the regulations governing the use of auto-pilots and reads as follows:
- Use of Auto-pilot – When the automatic pilot is used in areas of high traffic density, conditions of restricted visibility, or any other hazardous navigational situations, the master shall ensure that:
- It is possible to immediately establish manual control of the vessel’s steering;
- A competent person is ready at all times to take over steering control; and
- The changeover from automatic to manual control of the vessel’s steering and the reverse is made by, or under the supervision of, the master or officer of the watch.
- The USCG strongly recommends that vessel owners/ operators and masters to ensure that:
- The navigating staff is fully aware of “Use of Auto-Pilot” regulations found in the vessel’s respective subchapter in 46 Code of Federal Regulations.
- Conduct periodic training to ensure that crews are properly versed in the operations and limitations of the auto-pilot system.
- Develop and prominently post written procedures on how to switch from auto-pilot to manual control in the vicinity of the auto-pilot system.
- Review company policies and evaluate setting operational limitations on the use of auto-pilot with regard to areas of high traffic density, conditions of restricted visibility, or any other hazardous navigational situations.
- Ship Owners / operators and masters are advised to be guided by the attached USCG Marine Safety Alert.
- USCG Marine Safety Alert 10-16 Reg “Avoid Auto-Pilot Induced Casualties”.
