How it works
The International Safety Management (ISM) Code requires every ship operator to establish and maintain a Safety Management System (SMS): documented procedures for safe operation, pollution prevention, maintenance, emergency response and continuous improvement, with a designated person ashore linking ship and company.
Compliance is verified by a Document of Compliance for the company and a Safety Management Certificate for each ship. ISM made safety culture an auditable, certified requirement rather than a matter of goodwill.
