DNV GL has worked closely with the industry to support a smooth implementation of the BWM Convention. Below, we provide some hands-on advice on how to go forward:
Ship owner’s checklist
The most important tasks for a ship owner/operator to do now – in order of priority:
- Establish an overview of IOPP renewal dates for your fleet, and decide on a schedule for implementation.
- Retroactive Requirements (RR): for your individual vessels, compare your overview of IOPP renewal dates with specific RR messages posted in MyServices in Veracity. This overview helps you to manage due dates and necessary actions to ensure the proper follow-up of the retrofit requirements (e.g. RR Ref. 1034f, RR Ref. 1034g and MO Ref. 287).
- For ships that have done IOPP renewal between 8 September 2014 and 7 September 2017: The BWMC Reg. B-3.10.1 applies and the D-2 compliance date is the first IOPP renewal after 7 September 2017.
- For ships that have done the last IOPP renewal before 8 September 2014: check your fleet, especially laid-up vessels, and verify whether the last IOPP renewal survey was done before 8 September 2014. If this is the case, the first IOPP renewal after 7 September 2017 should be completed before 8 September 2019 (ref. Reg. B-3.10.2). This allows you to take full advantage of the due date for D-2 compliance, which is then on the second IOPP after entry into force. Otherwise, the BWMC Reg. B-18.104.22.168 applies and the D-2 compliance date changes; it will then become the first IOPP renewal after 7 September 2019. Appendix A illustrates this. Some owners will get the surprise of IOPP renewal and, at the same time, installing a BWTS when bringing vessels from lay-up to active trading.
- Assess and choose treatment technology based on its feasibility for your fleet. Choose the technology which has a Type Approval Certificate accepted by the flag state.
- Plan your retrofit, and ensure relevant documents are forwarded to class as early as possible.
Beware: Normally it takes 6 to 9 months from ordering the system, 3D scanning and design, and class approval of installation drawings, to installation and commissioning.
The approval of the installation drawings depends on their quality and the quality of the design, which again is reflected in the understanding of the rules, both statutory and class. DNV GL has developed a list of required documents (a DocReq) for the different types of treatment technology. This lists a minimum of drawings that should be submitted for approval. The document will be sent upon request when applying for approval. The approval process should be initiated at least 3 months before scheduled installation to account for handling any comments.
Below is a list of items which, based on our experience, requires attention by owners and designers:
- Type and model of the BWMT system: name and model of the system must be clearly stated in all documentation.
- Valid Type Approval Certificate (TAC): all systems shall have a valid TAC, issued by the flag or accepted by the flag of the vessel, e.g. issued by an RO to the flag (or has otherwise formally acknowledged the TAC).
- Stripping: procedures for how to treat the ballast water coming from the ballast tank during operation and equipment for stripping must be clearly described.
- Bypass in general and gravity bypass: all bypasses shall be logged and give an alarm.
- Sampling ports for D-2 compliance (biology): sampling pipe details, location and access to sampling ports.
- For systems using active substances (G9 systems, e.g. Electrolyzer, Chemical, or Ozone.): location and capacity of ventilation and monitoring of dangerous gas/liquid in the space of installation should be considered.
- BWM Plan: This should, as a minimum, contain what is in our template; see template “BWM plan template for D-1 and D-2” at dnvgl.com/bwm (needs to be re-approved for ballast water treatment if only D-1 has previously been approved).
When all documents have been approved and the system has been installed, there must be a commissioning and an initial survey by a DNV GL surveyor. If everything is in order, the surveyor will issue the International BWM Certificate (IBWMC) (with the box “D-2” ticked off).
- Review the “Ship owner’s checklist” as per above – and take action!
- Start the approval process in due course – and at least three months before installation.
- Ask class, flag and manufacturers in case of questions.

2020 Sulphur update - outcome of the MEPC 74
The 74th session of the Marine Environment Protection Committee (MEPC 74) was held at IMO in London on 13–17 May 2019. This was the last MEPC meeting before the 0.50% global sulphur limit takes effect on 1 January 2020, and the focus was on the implementation and completion of guidelines to help stakeholders prepare and ensure consistent implementation. We strongly recommend stakeholders to prepare in due course and update plans according to the latest IMO guidance. This statutory news contains a summary of sulphur-related resolutions and circulars adopted at MEPC 74.
EU MRV and IMO DCS - some practical recommendations
This technical news contains some recommendations relevant to both EU MRV and IMO DCS.
Prepare for the Global Sulphur Cap 2020 with the IMO Ship Implementation Plan
The IMO has agreed on 1 January 2020 as the date for switching to 0.50% sulphur fuel globally. Now, as ship owners face the daunting task of preparing for the fuel oil switch, proper planning is essential. The IMO Guidance for developing a Ship Implementation Plan (SIP) is a useful tool, and described further in this technical news.
Survey by remote inspection techniques - use of approved service suppliers
The use of remote inspection techniques (RIT) is increasing. Today, drones, climbers, or robot arms, can be used as an alternative to close-up surveys in both the DNV GL rules and IACS Unified Requirements. RIT may significantly reduce the survey time and costs, while improving the safety of surveyors and the owner’s personnel. From 1 January 2019, DNV GL has approved the use of service suppliers for RIT. This technical news explains how RIT can be used and how suppliers can achieve DNV GL approval.
IMO requirements July 2018 to May 2021
This statutory news summarizes the most important IMO requirements entering into force from 1 July 2018 up to and including 31 May 2021.
Outcome of the IMO SSE 6 meeting - from habitable life boat environments to Ro-Ro deck fires
The IMO sub-committee on Ship Systems and Equipment (SSE) met in London on 4–8 March 2019. This statutory news summarizes the main topics discussed, such as, life-saving appliances, fire safety of Ro-Ro passenger ships, and on-board lifting appliances. All agreements made at the meeting are subject to final approval by MSC 101 in June 2019.
Recommissioning of laid-up ships and mobile offshore units - how to avoid surprises
When the market moves back from a downturn, vessels are leaving the lay-up buoys and the focus shifts from preservation to recommissioning. DNV GL has accumulated its best practices into a revised Recommended Practice (RP) containing a new approach for assurance of non-class equipment and systems during recommissioning.
Sulphur limit in ECAs - increased risk of PSC deficiencies and detentions
DNV GL keeps customers and other stakeholders updated on various aspects of the global 2020 sulphur cap and its implications for maritime shipping. While the global cap of 0.5% is just around the corner – entering into force on 1 January 2020 – this PSC news focuses on existing emission control areas (ECAs) with a 0.10% sulphur limit and the role of port state control (PSC) inspections.
