"It is the job of ship registries to ensure the effective, efficient and practical implementation of rules and regulations, said Scott Bergeron, UK chief of the Liberian International Ship & Corporate Registry.
"Unfortunately, there are other regulators who are not enforcing the rules effectively and this is really troublesome because the result of ineffective implementation is yet more regulation.
"The industry already has enough regulations and creating new ones just as a political or public reaction to accidents is very short-sighted," said Mr Bergeron.
"The ISM [International Safety Management] Code should be the last regulation from IMO, because every new requirement, whether political, environmental or safety-related, could be incorporated into ISM," he said.
"We don't need new conventions. We don't need new regulations. What we need is for everything to be encapsulated in a single operating concept such as the ISM Code.
"Liberia applauds IMO and calls on other flag states to work together with Liberia to achieve effective implementation of existing regulations. Too much time, too much energy and too much expense has been wasted on new regulations. Let's focus on the ones we have," Mr Bergeron said.
