From international convention to Danish legislation
The most important IMO 'product' is the various international conventions negotiated, adopted and ratified by the Member States. Supplementing and elaborating on the conventions, the IMO has also adopted a number of 'codes', typically dealing with a specific technical area.
When Denmark has ratified a convention and it has entered into force, the Danish authorities are responsible for enforcing it, i.e. ensuring that Danish ships meet the requirements of the conventions.
Conventions normally enter into force once a sufficient number of IMO Member States have ratified them. In practice, this number is often defined on the basis of the total tonnage of the ratifying countries. A status on the level of ratification of the various conventions is available from the IMO webpage.

When Denmark ratifies IMO regulation, it is subsequently transposed into Danish law. In some cases, the EU transposes EU regulation into EU directives and regulations, which are then implemented at national level in the individual legislative works of the EU Member States.
