The Emissions Compliance Corner

07-07-2022: The 78th MEPC meeting took place 6–10 June 2022, this time as a virtual event. Many topics were discussed, but in this blog post I’ll highlight the most important developments related to emissions compliance.

23-03-2022: Let me start this post with a small caveat: I am not an expert on the regulation of energy efficiency on ships. This type of regulation has been around since 2012, so technically I’ve had the time to learn. However, it first became a priority when it began to cross over into my own focus on emissions.

17-02-2020: A report issued in August by CE Delft, details a new study named “Comparison of CO₂ emissions of MARPOL Annex VI compliance options in 2020”, which I will nickname the “WtW study” in reference to its well-to-wake scope. In my new blog I examine the study.

12-02-2020: Next week, IMO’s PPR (Pollution Prevention and Response) subcommittee will have their 7th meeting (PPR 7). The plan for this meeting is to revise the 2015 EGC guidelines. This task has been in the pipeline for the last two years, but more pressing matters such as “IMO 2020” (the global sulphur cap) have led to constant postponements.

16-01-2020: The question above is asked very frequently, and it still has no definitive answer. Let’s look at why the water quality rules for an exhaust gas cleaning system (ECGS) might – or might not – apply to an inert gas system.

06-12-2019: In May of this year, new guidance was approved by IMO’s Marine Environment Protection Committee (MEPC) and circulated as MEPC.1/Circ.883.

16-12-2021: Many things were discussed at MEPC 77, including greenhouse gas emissions, black carbon, plastic litter and ballast water. In this blog, however, I’ll highlight the topics that are of interest to exhaust gas cleaning systems.

26-05-2021: Late in March, IMO’s Pollution Prevention and Response (PPR) sub-committee held its 8th meeting. This was yet another crossroads for the discussion on black carbon (BC), hinging on the question of what to do next.

31-03-2021: During MEPC 75, all work related to EGCS was postponed. What was concluded during this meeting? And what will be discussed during MEPC 76? I give my thoughts in this blog.

05-05-2020: In my last blog post, I touched upon how the draft EGCS Guidelines now define the PAH monitoring methodology. I also wrote that PAH as a regulatory substance for scrubbers can be difficult to comprehend. So, in this blog post I’d like to clear up some of the PAH mystery.

25-03-2020: It’s been about a month since the PPR (Pollution Prevention and Response) meeting in London. What, then, is the verdict from a scrubber manufacturer perspective? Or are you more interested in what impact the agreed outcome will have on shipowners?

06-11-2019: Since 2015, China has slowly expanded what it calls the Chinese Domestic ECAs, where ECA is short for Emission Control Area. These ECAs should not be confused with the ECAs defined by IMO.

24-09-2019: The 2020 global sulphur cap is just around the corner. In various other corners, I hear a lot of discussion: how it is even possible to enforce this regulation?

10-09-2019: Describing scrubber sludge as a substance explains that scrubber sludge comes in wide range of viscosities depending on the cleaning equipment installed on board. The majority of ship owners prefer to be able to pump the sludge from ship to shore. The other alternative is to truck/lift it from the ship.

10-09-2019: From an Alfa Laval point of view, scrubber sludge is waste collected during scrubber operation in closed-loop mode. For other suppliers, it can also be a substance collected during open-loop operation. But this post is written from our perspective on the world.
