The IMO and regulations:
Since July 2018, the EU has required ship owners to provide information for EU-regulation 2015/757. This requires ship owners and operators to annually monitor, report, and verify CO2 emissions for vessels larger than 5,000 GT and which call at any EU port on a per voyage basis.
However, regulations covering a vessels fuel efficiency were introduced by the IMO in 2020 in the form of Carbon Intensity Indicators (CII). Regulations on mass emissions are increasing, with individual CII targets even being discussed in MEPC 75. Each year these regulations are discussed and heightened with the IMO’s focus moving on from CO2 to other emissions. With the growth of the LNG industry, methane slip is especially being considered, and greater regulation encouraged internationally.
With charterers under pressure to provide monthly figures for energy giants and their CSR reports, exact emissions measurement is a valuable tool. Currently, charterers estimate emission output based on fuel input, but with the iS providing accurate measurement of emissions output, overestimating is impossible, and shipowners are able to future proof against per-unit fees and emission credits.
Each year there is a growing emphasis on the collective greenhouse gas output of the shipping industry. Most notably by the European Commission to create a bench-marking system for the EU’s policy for reducing domestic greenhouse gas emissions. The UN and it’s internationally applicable Paris Agreement is also relevant in the regulation of greenhouse gas emissions by the maritime industry.
Mass emissions capability is surprisingly not found in all Emissions Monitoring Systems, but with the rise of LNG, it has become a necessary part of any shipowner’s toolkit.
The total methane slip from both the production of methane and the inefficient combustion of LNG in marine engines is significant. Methane is the particular concern not only of organisations like the IMO, but of the maritime industry as a whole. Higher levels of pollution mean more regulations, fines, ECAs, taxes, and costly fuel tokens to offset the damage, and of all the greenhouse gases Methane is one of the most unpleasant. Methane is 84 times more potent than carbon dioxide because of how quickly it absorbs heat.
Emsys Maritime made sure to consider specialist applications in the design of our EMS, resulting in the Emsys-iS. With modular gas options and additional capabilities like Particulate Matter monitoring, the iS platform has Mass Emissions Reporting refined in one of the most compact systems in the market. This Mass Emissions capability accurately measures total emittance of any pollutant gas needed, in whatever combination, and from multiple engines. This makes the iS a powerful tool for any shipowner considering or already using LNG.
LNG fuel and it’s unfortunate methane slip problem is not going away any time soon, in fact the opposite, as there is still the widespread agreement that LNG fuel is the way forward to the maritime industry’s collective decarbonisation. Shipowners must prepare for the fallout of methane slip with emissions monitoring systems that have mass emissions capability.
