ANNEX 1 RESOLUTION MEPC.252(67) Adopted on 17 October 2014

2.5.2 If a ship has violated the BWM Convention, the PSCO may take steps to warn, detain or  exclude  the  ship  or  grant  such  a  ship  permission  to  leave  to  discharge  ballast  water  
elsewhere or seek repairs.

The PSCO should use professional judgment to determine whether to  detain  the  ship  until  any  noted  deficiencies  are  corrected,  or  to  permit  a  ship  to  sail  with  deficiencies  that  do  not  pose  an  unreasonable  threat  of  harm  to  the  marine  environment,  human health, property or resources (see notification requirements in paragraphs 3.3 to 3.6 below).

2.5.3 In  order  to  assist  the  PSCO  in  the  use  of  these  guidelines,  there  follows  a non-exhaustive list of deficiencies which are considered to be of such a serious nature that they may warrant the detention of a ship:
1 absence of an IBWMC;
2 absence of a BWMP;
3 absence of a BWRB;
4 indication that the ship or its equipment does not correspond substantially with the particulars of the IBWMC and BWMP;
5 absence,  serious  deterioration  or  failure  of  proper  operation  of  equipment  required under the BWMP;
6 the designated officers or crew are not familiar with essential ballast water management   procedures   including   the   operation   of   BWMS   and   all  associated BWMS equipment;
7  no ballast water management procedures have been implemented on board;
8  no designated officer has been nominated;
9  the ship has not complied with the BWMP for management and treatment of ballast water;  
10 result of non-compliance by sampling; or
11 ballast  water  has  been  discharged  other  than  in  accordance  with  the regulations of the BWM Convention (regulation A-2).
