What are the following stages?

Until 31^st March 2020, companies have to submit fuel oil consumption data (of the previous calendar year) to the Flag State for approval. After the information is submitted, it is verified by the classification societies, which by the latest of 31^st May 2020 will issue the vessels a Statement of Compliance. This document should be kept on board and is valid during the calendar year for which it has been issued and extended to the first five months of the subsequent calendar year.

From June 2020 onwards an annual submission of the aggregated and verified data will be made to IMO as per Regulation 22A. Classification societies have been launching tools to facilitate IMO DCS compliance with regulations, namely starting initiatives to help operators like software for reporting and monitoring data. Bureau Veritas, for example, launched an app for users to submit their SEEMP online and at the end of the process allows downloading their Confirmation of Compliance.

Conclusions

It is expected that both IMO DCS and MRV legislation will work in parallel, at least for the following years, being their goal and ambition to reduce GHG emissions from maritime activity. EU MRV and IMO DCS intend to be the first step in a process to collect and analyse emission data related to the shipping industry. The outcome of the reports has the common goal to reduce 6noxious emissions from the shipping business and more in general to mitigate climate change.

The data and aggregated information collected through both regimes might then eventually be used in the future to cut emissions through the introduction of an Emission Trading Scheme or by providing incentives to owners. For IMO, the Greenhouse Gases (GHG) strategy for 2050 was agreed in the 72^nd MEPC aiming at a reduction of GHG by 50% by 2050 compared to a baseline of 2008. The measures to achieve this goal will be based largely on the information that will be gathered through the framework IMO DCS.

Unplug equipment from the wall

Lower your carbon footprint by forming good habits. The combustion of materials to produce electricity contribute to the greenhouse effect. Standby mode will consume a small amount of power, so unplug equipment from the power sockets when not in use. This also applies to kitchen appliances.

Encourage energy-efficient transport

Air transport is the worst offender for emissions. Where possible, make use of rail, road and sea transportation instead. Switch your company cars for hybrid cars and encourage carpooling to and from the workplace.

Upgrade technology

A great way to reduce emissions in the digital age is to use fibre. It transmits data over longer distances and utilises less energy than conventional copper cables. Plus, this high-speed internet is a great option for productivity in the workplace.

Reuse and recycle

Go paperless to save on waste. With today’s advancements in technology, this is easy to achieve. Have designated recycling bins and collect food scraps for composting. Buy work supplies in bulk from companies that do not use unnecessary plastic packaging. You could also consider buying second-hand items for your workplace. This includes furniture, kitchen appliances and office equipment.

Be energy-efficient

Use solar heaters for both power and water. The upfront cost for solar panels and systems is high, but you will reap the benefits in the long run.

Use LED and energy-saving bulbs to consume less energy. Not only are they energy-efficient, but their longevity means they will require less frequent replacements. This will also save your business money in the long run. Motion sensor lighting is another great way to save energy.

Decorate with plants

Many offices have wall art or sculptures. Using plants as your office’s art will offset your carbon footprint. Plants absorb carbon dioxide as part of the photosynthesis process.

You could even grow a vegetable and herb garden outside your workplace. Employees could help maintain the garden in exchange for free use for their own lunches.

Work with environmentally-conscious businesses

Work with businesses that offer environmentally-conscious solutions. Choose office or kitchen supplies with minimal plastic packaging or recyclable packaging. There is a huge environmental impact of aviation. With emissions through air transport high in greenhouse gases. So, when purchasing goods for the office or looking for suppliers, choose companies that ship by sea rather than air.

Consider means of ventilation and heating

Air conditioning is an energy-efficient means of cooling a space. However, air conditioning units emit potent greenhouse gases. Where possible, open a window or door for ventilation.

On the contrary, heating a building can use a lot of power. An insulated office will reduce heat loss and the need to heat a space. Be sure to block any drafts that will allow warm air to escape.

Energy consumption of businesses has a huge environmental impact, and little changes go a long way. Adapt your business to the numerous approaches in carbon footprint reduction. Not only will you cut costs in the long run, but you will also be saving the Earth, so future generations can thrive.

Fossil fuels are used in a large part of the items we use on our daily basis. One major use of these products is fuel, for example, gasoline or diesel for cars, HFO is used in vessels´ main engines and for industrial applications, such as jet fuel, heating oil, and natural gas which can be used to generate electricity, among others. Although there is a more recent trend in searching for greener fuel alternatives (like hydrogen, liquefied natural gas or methanol), alongside the benefits there are new safety concerns that need to be taken seriously, and a lot of technological development yet to be made.  Therefore, it could be said that there is still a long way until decarbonisation is achieved, and fossil fuels will surely continue to be a constant in the present and following years.

Business sectors, such as industrial plants and shipping, use HFO as a dominant fuel of choice, as it provides the best combination of power and present low costs. HFO is less expensive since it is not so refined as diesel fuel. It also contains more energy per gallon than lighter fuels.

In exchange for its lower cost and higher energy content, the trade-off comes from the fact that these fuels also have higher levels of harmful inorganic components like sulphur, vanadium, silicon and other metals. The high levels of metals and sulphur can be disastrous to engines since there are often concerns with corrosion damage for these types of equipment and its associated parts. The sulphur from the fuel reacts with oxygen during combustion and is oxidized in the engine, with the vanadium contributing through a catalytic role.

Figure 1 – Although there are many concerns about the usage of fossil fuels because of the environment and its shortage it will take severall years until we replace it for alternative greener fuels.

In the engine combustion chamber, SO₂ and SO₃ are produced and these gases will combine with water vapour already present (combustion produces CO₂ and water as by-products) resulting in the formation of sulphuric acid. The sulphuric acid condenses onto metal surfaces as the exhaust gases cool, resulting in corrosion damages. This is bad news for expensive engines, fuel systems, and exhaust emissions equipment.

Another conventional problem that can occur with fuel batches is the contamination with water. If water has entered in a fuel or oil tank, the system and operation could be in big trouble as it can wreak havoc on the machinery, equipment, and vehicles. As water is incompressible, if the contaminated fuel enters a combustion chamber it can be disastrous. In fact, water is a natural element, and unfortunately, most tanks and equipment are not fully resilient to water. In addition, if the water is left for a long period the inside of a tank will begin to corrode. Therefore, unless users do regular checks, they will not be aware of the problem until operational problems begin to occur.

Besides water, sediments, metals, and sulphur, it is also fundamental to check on the physical properties of the fuel, for example, its density and viscosity.

It is essential to measure density due to the way fuel is supplied. For example, in maritime applications, the fuel is generally delivered from a bunker barge and the volume of the transfer is measured often by a flowmeter. Nevertheless, the mass is directly proportional to the power that can be gained from using the fuel, so an accurate density calculation has a direct financial value associated. By using equipment such as density meters, it is possible to accurately determine the fuel density and confirm that the correct grade has been delivered.

Testing the viscosity of fuel oil is also important for several reasons: not only does it allow its user and to verify that the correct amount of fuel has been delivered/is being used, but there are also several benefits when it comes to the handling of the fuel. Testing allows the combustion performance to be calculated and determines the temperature at which the fuel should be handled. Therefore, density and viscosity accurate determination will have an implication of the combustion performance (CCAI – Calculated Carbon Aromaticity Index).

Another concern when using this type of fuel is the fact that bulk fuel stored for long periods can become unstable – the asphaltene content can precipitate out of solution causing the formation of sludge. This has the potential to block filters and pipes, leaving tanks with an unpumpable residue. The industry best practice is to avoid mixing fuels from different sources and with different formulations as it can lead to incompatibility problems and a loss of stability in the resultant blend. For example, when HFO with a high asphaltene content is mixed with a low-gravity distillate with a predominance of paraffinic aliphatic hydrocarbons, the solvency reserve can be depleted and asphaltenes can flocculate and precipitate as sludge. Therefore, both the asphaltenes content and the stability are parameters to be monitored.

For the ASTM D4740 spot test, a blend composed of representative volumes of the sample fuel and the blendstock is heated and homogenized. A drop of the blend is put on a test paper and heated to 100°C. After 1 hour, the test paper is removed from the oven and the resultant spot is examined for evidence of precipitation and rated for compatibility against D4740 reference spots

Such problems can be avoided by systematic checking and monitoring fuel batches. TecnoVeritas provides one such solution, the Fuel Lab – Portable Fuel & Lubricating Oils Laboratory. Fuel Lab is a portable Laboratory developed for fuel and oil analysis. It can be applied to industry and marine installations (vessels) that require the use and complete characterization of Fuel Oil, HFO, MGO, MDO, and Lube Oil. The majority of the tests follow international ISO and ASTM standards and comprise all necessary materials (equipment, laboratory glassware, chemicals, and consumables) and analysis guides to grant its user the possibility to evaluate the characteristics of its product and confirm its conformity according to the levels of each parameter. With this useful tool, users can take proper actions and also avoid future burdens.

Tecnoveritas laboratory team may also receive fuel/oil samples, analyse and provide a technical report, guaranteeing an independent and impartial analysis delivered to our clients.
