FAQs
IMO (International Maritime Organization) conventions are international agreements designed to promote safety at sea, protect the marine environment, and ensure secure and efficient shipping. They establish global standards for ship construction, navigation, pollution control, and crew safety.
Some of the key IMO conventions include:
SOLAS (Safety of Life at Sea): Ensures the safety of ships and passengers.
MARPOL (Marine Pollution): Prevents marine pollution from ships.
STCW (Standards of Training, Certification, and Watchkeeping): Sets training and certification standards for seafarers.
COLREG (Collision Regulations): Establishes rules to prevent ship collisions.
IMO conventions are enforced through national governments that are signatories to the agreements. They are responsible for implementing the regulations in their domestic laws and conducting inspections and certifications to ensure compliance. Port State Control inspections are also conducted to monitor compliance with these conventions.
IMO conventions are periodically reviewed and updated through amendments to address new challenges, technological advancements, and environmental concerns. These amendments are adopted through the IMO’s committees and require ratification by member states before they come into force.
