Danish Shipping releases new guide ahead of BWM Convention

Danish Shipping releases new guide ahead of BWM Convention

Introduction
As the Ballast Water Management Convention is entering into force on 8th September, Danish Shipping launched a new guide to advice on its implementation. The guide is intended to be on board the ships, so the crew can seek information when needed. All ships are required to have a ballast water management plan and those above 400 GT are subject to surveys.
Ships not regulated by BWMC
1. Ships without ballast water
2. Ships with sealed or permanent ballast water tanks
3. War ships, naval auxiliary and other government ships

 

Certificates and documents
If vessel is >400 GT you must have one of the following certificates onboard:
• International Ballast Water Management Certificate (IBWMC);
• Statement of Compliance.
You must have the following documents on board:
• An approved Ballast Water Management Plan ( BWMP);
• A Ballast Water Record Book (BWRB);
• Type approval Certificate for Treatment System.

Ballast Water Exchange Standard D-1
Existing vessels shall apply the D-1 Ballast Water Exchange Standard (BWE) until the must comply with the D-2 standard. The compliance standard is recorded in the IBWMC.

Ballast Water Performance Standard D-2
Once the vessel has to comply with the D-2 standard it must have on board:
• IBWMC confirming compliance with D-2 standard;
• A type approved BWMS installed;
• An IMO type approval certificate;
• An approved Ballast Water Management Plan;
• Operational and safety manual for the BWMS;
• An installation survey report to confirm compliance of type approval requires.
The ballast water treatment process for a typical in-line BWMS with a filter and a treatment unit. Some systems avoid the filter unit, some treat a second time on discharge and some include a neutralization system for the discharge water. A few BWMS are in-tank systems that treat during voyage. The IMO has decided that the first five years after BWMC entry into force is an “experience building phase” for the management of ballast water. If a vessel operates under exception or exemption valid for certain locations no discharges are allowed if mixing with unmanaged ballast water and sediments from other areas has occurred.

Preparation for Port State Control
Stage 1
Initial inspection
PSC officer will:
• Inspect documentation (Certifications, BWMP and BWRB);
• Check that an officer has been appointed for the BWM on board;
• Check familiarity of the responsible officer and crew with the BWMS;
• Visual inspect overall condition of the ship, the equipment and arrangements detailed in the certificate BWMP and BWRB.
Stage 2
More detailed inspection
PSC officer will:
• Clarify whether detailed BWMP operational procedures are followed (safety, sediments, record keeping cross check);
• Check if BWM has been conducted according to the BWMP;
• Check of BWMS operational record, including self-monitoring devices;
• Follow up on bypass and emergency issues.

Stage 3
Indicative analysis
• Limited sample taking is expected;
• Indicative analysis may involve the use of portable analytical instruments.
Stage 4
Detailed analysis
• Full verification of compliance may involve large scale sampling typically requiring specialists onboard assisting the PSC officer;
• Samples for compliance testing are sent to laboratories onshore and analysis are time consuming.
