while undertaking an inspection under the already implemented regular inspection
programme. Further to such programme, BWM specifi c elements to trigger the
CME process have been identifi ed. According to the BWM Convention, the verifi -
cation process has two levels. Triggering elements have been grouped accordingly.
Each of these can trigger the compliance monitoring process directly or randomly.
A vessel targeted by the selection process enters the CME process. According to the
BWM Convention Article 9, a vessel to which the BWM Convention applies may be
subject to inspection in any port or offshore terminal of the port State that is party to
the BWM Convention. The purpose of such inspection is determining whether the
vessel is in compliance with the BWM Convention. Even if the BWM Convention
has not yet entered into force, every state has to provide for an effective verifi cation
process to support effective implementation of the BWM measures.
The verifi cation process has two levels, the “regular inspection” and the “detailed
inspection”. The main differences of the two levels are the triggering elements, as
well as the consequences for the vessel during the inspection process.
The so called regular inspection does not need special justifi cation for the trig-
gering elements, and as such can be understood as part of the basic and regular PSC
inspection process. It can be further divided into simple paper inspection and BWS
for compliance. The simple paper inspection includes:

- verifi cation that there is a valid BWMS certifi cate on board the vessel; 9 and

- inspection of the BWRB.

BWS for compliance has basically two different approaches:

- BWS for salinity (D-1 standard compliance); and

- BWS for D-2 standard compliance.

The BWS for salinity is generally intended to be used for a verifi cation of the
BWE process, and specifi cally for the verifi cation of the RA process when a deci-
sion was taken based on environmental matching salinity. The BWS for compliance
with the D-2 standard requires analyses of viable aquatic organisms present in the
ballast water.
The BWS for compliance should be conducted according to the Guidelines for
ballast water sampling (G2) (IMO 2008 ) and its related guidance documents. If
BWS is conducted as a part of the regular inspection, the vessel shall not be unduly
delayed for the time required to analyse the ballast water samples. For more details
about BWS see chapter “ Ballast Water Sampling and Sample Analysis for
Compliance Control ”.
A PSC may also decide to carry out a detailed inspection when a ship does:

- not carry a valid BWMS certifi cate; or there are

- clear grounds for believing that:

9 If valid, it shall be accepted.
