ISM Code
The mandatory IMO framework for safe management and operation of ships — basis of the Document of Compliance and the Safety Management Certificate.
Definition
The ISM Code is the management-system standard for shipping companies, made mandatory under SOLAS Chapter IX. Every commercial vessel above 500 GT on international voyages must operate under an approved Safety Management System, audited by the flag administration or a recognised organisation. The company holds a Document of Compliance (DOC), each ship holds a Safety Management Certificate (SMC), and both are subject to PSC inspection. ISM non-conformities are a frequent PSC detention trigger.
How Vessel Hunter uses ISM Code
Vessel Hunter tracks the ISM Manager separately from the registered owner — because in commercial maritime, the ISM Manager is often the right first contact, not the holding company on the title deed.

The bigger picture
ISM Code is one piece of the commercial maritime picture Vessel Hunter pulls together for shipyards, port agents, and service providers. Every vessel record bundles AIS, ownership, inspections, dry-dock history, casualty record, classification status, and a verified contact for the operator decision-maker behind the ship — so the team that reaches out first wins the work.
