What is the ISM Code?

International Safety Management Code (ISM Code) is the International Management Code for the Safe Operation of Ships and Pollution Prevention, as adopted by the IMO assembly. Adopted in November 1993, the ISM Code came into force in July 1998. It is part of the SOLAS Chapter IX - Management for the Safe Operation of Ships. The latest amended version came into force on January 1, 2015.

The Code aims to support and encourage the development of a safety culture within the shipping industry while improving compliance with the requirements of international conventions. Three basic principles of the ISM code include the safety of - the people on board, the ship and cargo, and the environment.


Who is responsible for the ISM Code implementation?

The company is responsible for the implementation of the code. The code defines the company as the owner of the ship, any other organization, a manager, a bareboat charterer, or any other entity that has assumed responsibility for the operation. The code establishes safety management objectives and requires a safety management system (SMS) to be implemented by the company which operates a ship.

Who Should Comply with ISM Code?

The ISM Code applies to all ships now, and compliance is mandatory for passenger and cargo ships of 500 gross tonnages and upwards engaged on international voyages under SOLAS clauses. The procedures required should be well documented and compiled in a Safety Management Manual, a copy of which should be available on board for ready reference.
