After the BWM action has ended and the vessel has undertaken (or not) the required
BWM practice, she may be selected for the verifi cation process to verify compliance
with the requirements, i.e., compliance monitoring and enforcement (CME) process.
Compliance Monitoring and Enforcement
The CME process is in the fi rst place intended to back-up the management process,
and to support the full implementation of the BWM Convention and any further port
State BWM requirements. Every vessel allowed to enter the port may be selected
for compliance monitoring. If a vessel is found not compliant, but has already
entered the port and started deballasting, it may be stopped from deballasting and
may be requested to take alternative BWM measures. The compliance monitoring
process is followed by the penalty process for non-compliant vessels. A penalty
