Exhaust Gas Cleaning Systems

/ Blog /
Ship Store Bonded Provisions Logistics Maritime

Exhaust Gas Cleaning Systems, also known as scrubbers, are an innovative technology that address the environmental impact of the maritime industry.

 

Ships are recognized to produce significant air pollution by discharging exhaust gases, mainly sulphur oxides (SOx), nitrogen oxides (NOx), and particulate matter (PM).

 

The International Maritime Organization (IMO) has introduced many regulations to reduce air pollution and greenhouse gas emissions.

 

But scrubbers are one of the most efficient ways of reducing the environmental impact of shipping.

 

The global maritime industry is responsible for producing around 940 million tons of carbon dioxide (CO2) every year.

 

It is estimated that international shipping accounts for around 2.2% of global CO2 emissions.

 

Despite accounting for a relatively small proportion of gas emissions, the shipping industry is committed to reducing its impact and being part of the global fight against climate change.

 

An Innovative Solution

Exhaust Gas Cleaning Systems are an innovative solution implemented by ship owners to reduce their environmental footprint.

 

Scrubbers work by removing pollutants and particulate matter from the exhaust fumes produced by marine engines.

 

The systems consist of a variety of technologies that typically employ the process of washing and purifying emissions.

 

Types Of Scrubber

The two most common types of scrubber are closed-loop and open-loop scrubbers.

 

– Closed-Loop

Closed-loop scrubbers work by mixing seawater with a buffering agent that neutralizes the acidic exhaust fumes.

 

The neutralized mixture is then returned to the ocean, reducing the release of acidic pollutants.

 

This type of scrubber is primarily employed in zones with a limited water supply or where the discharge of effluent can be problematic.

 

– Open-Loop

Open-loop scrubbers, on the other hand, use seawater as a medium for scrubbing the exhaust gases.

 

The seawater reacts with the sulfur dioxide (SO2) in the exhaust gas to form sulfate particles, which then settle on the sludge waste.

 

The residual seawater is discharged into the surrounding waters. This type of scrubber requires a great deal of seawater, making it less suitable for areas with a limited water supply.

The Controversy

Although scrubbers have been praised for their environmental benefits, they have also courted controversy among some quarters.

 

Environmental advocates argue that open-loop scrubbers can increase pollution in waterways due to the amount of effluent discharged.

 

At the same time, some experts have pointed out that the cost of installing a closed-loop scrubber is relatively high.

 

A Potential Tool

Despite the controversies, scrubbers have emerged as a critical tool in the fight against climate change in the shipping industry.

 

Many firms see scrubbers as a means of reducing their environmental footprint and achieving regulatory compliance.

 

The IMO has introduced a range of regulations requiring ships to limit their emissions and use of low-sulfur grade fuel oils.

 

Cost-Effective

Scrubbers are considered a compliant and cost-effective means by which ship owners can meet these regulations while continuing to use less expensive high sulfur fuel oils.

 

In addition to reducing air pollution, scrubbers can also make economic sense for ship owners.

 

The installation of scrubbers can be expensive, but the use of high sulfur fuel oils can be cheaper than low sulfur fuel oils.

 

By using scrubbers, owners can save on fuel costs while meeting environmental regulations.

 

The implementation of Exhaust Gas Cleaning Systems is gaining popularity in the shipping industry.

 

As of early 2020, there were over 4,000 ships fitted with scrubbers, providing an estimated installed scrubber capacity of over 50 million tons.

 

A Developing Technology

Moreover, scrubbers are a developing technology, and its manufacturers are working to enhance the effectiveness and efficiency of these systems.

 

Another aspect to be considered is that, while scrubbers play a vital role in improving the environmental footprint of the shipping industry, they are not a silver bullet.

 

Shipping companies must pursue multiple strategies to reduce their carbon footprint, including the use of alternative fuels, energy-efficient vessel design, and operational optimization.

 

In Conclusion

Exhaust Gas Cleaning Systems are an innovative solution implemented by ship owners to reduce their environmental impact.

 

Despite some controversies surrounding the technology, scrubbers are emerging as a critical tool in reducing air pollution from the shipping industry.

 

Scrubbers can provide an economic advantage, but they should be used in conjunction with other strategies to ensure a reduction in carbon emissions.

 

As the industry continues to grow, the use of scrubbers and other solutions is likely to become even more widespread in the coming years.

/ Blog /
Ship Store Bonded Provisions Logistics Maritime

In recent years, there has been growing concern about the environmental impact of shipping, particularly with regards to greenhouse gas emissions.

 

Carbon emissions from shipping account for around 2.5% of global CO2 emissions, and this is projected to double by 2050 if nothing is done to reduce emissions.

 

One of the solutions to reducing carbon emissions from shipping is through Wind Assisted Propulsion Systems (WAPS).

 

What is WAPS?

WAPS are a type of technology that harnesses wind power to supplement or replace traditional diesel engines, reducing a vessel’s fuel consumption and emissions.

 

WAPS include technologies such as Rotors, Sails, Kites, Flettner Rotors and other new innovations.

 

This technology has been around for a long time. In the early days of shipping, ships were powered solely by wind power in the form of sails.

 

More recently, there has been growing interest in the use of WAPS as a way to reduce fuel consumption and emissions in the shipping industry.

 

Types of WAPS

– Sails

One of the most common types of WAPS is the use of sails. Sails can be retrofitted onto existing vessels or built into new vessels.

 

The use of sails offers several advantages, including reducing fuel consumption, the potential to increase a vessel’s speed, and reducing emissions.

 

There are two types of sails commonly used in shipping: traditional square sails and modern “aerofoil” sails.

 

Square sails are more traditional and are based on the same principles as those used in the early days of sailing ships.

 

Aerofoil sails are more modern and more aerodynamic, and can be used to drive a ship even into the wind.

 

– Rotors

Another type of WAPS is the use of Rotors. Flettner Rotors work by rotating around a vertical axis, creating lift similar to a helicopter.

 

The rotors are powered by the ship’s electrical system, meaning they do not require any additional fuel.

 

The use of Flettner Rotors can help to reduce fuel consumption and emissions, though the cost of installing and maintaining these systems can be high.

 

– Kites

Kites are also a WAPS option in shipping. A kite system consists of a large kite, which is tethered to the vessel.

 

The kite pulls the ship along and can help to reduce fuel consumption and associated emissions.

 

Kite systems offer advantages, lower fuel consumption, reduced emissions, potential increases in vessel speed, and the ability to operate in a variety of wind conditions.

 

There are other WAPS innovations being developed which include multiple sails/masts, airfoils, and rigid wings to increase propulsion, further improving the efficiency of WAPS.

 

Progress in these technologies shows promising results and implementations in international shipping fleets.

Given the rising demand for sustainable shipping practices, WAPS have become more popular in the shipping industry.

 

Major shipping companies have made public commitments to invest in WAPS technology, recognizing it as a promising solution to reduce greenhouse gas emissions.

 

The Main Benefits

The potential benefits of WAPS in the shipping industry are immense.

 

According to a study by the International Windship Association, using WAPSs alone could reduce global ship emissions by up to 30%, equal to removing 6 million diesel cars from the road every year.

 

Furthermore, as governments and societies around the world become more aware of environmental issues, WAPS could provide a vital tool for reducing emissions and combating climate change.

 

Challenges

However, there are also challenges to developing and implementing WAPS in the shipping industry.

 

Upfront costs for retrofitting, installation, and maintenance can be high, and the technology hasn’t been fully adapted to the specific requirements of the shipping industry.

 

Additionally, wind conditions can be unpredictable, which can impact the efficiency. However, ongoing research and development are rapidly increasing the effectiveness and feasibility.

 

Conclusion

WAPS have the potential to revolutionize the shipping industry by reducing greenhouse gas emissions, lowering fuel costs, and improving the efficiency of shipping overall.

 

While there are still challenges to address, continued investment and development of WAPS technology could transform the industry to a more sustainable and environmentally-friendly future.

Beyond Borders: Geopolitical Tensions in the Maritime Industry

/ Blog /
Ship Store Bonded Provisions Logistics Maritime

Geopolitical tensions can have a profound impact on the maritime industry all over the world.

 

From piracy and smuggling to border disputes and sanctions, the shipping industry must navigate a complex and rapidly changing landscape.

 

In this article, we will explore the opportunities and risks associated with geopolitics and how they affect the maritime industry.

 

Free Flow of Goods and Services

At the heart of the issue is the free flow of goods and services across borders.

 

Shipping companies and ports rely on this free flow of trade to keep commerce moving and ensure the global economy remains vibrant.

 

However, geopolitical tensions such as trade disputes, economic sanctions, and border disputes can interfere with this trade.

 

Countries engaging in such activities may restrict the movement of ships through their waters or impose tariffs and fees on imported and exported goods.

 

– United States and China

One of the most significant recent examples of geopolitical tensions impacting the maritime industry is the ongoing trade war between the United States and China.

 

As the two largest economies in the world, any tension between them quickly ripples across international trade.

 

Both countries have imposed tariffs on each other’s goods, causing a decline in US-China trade.

 

This decline in trade directly impacts the shipping industry, reducing the volume of goods being transported across the Pacific and resulting in lower revenues for shipping companies.

 

– Piracy and Smuggling

Another area of concern is piracy and smuggling. Piracy has been a long-standing issue in particularly dangerous areas such as the Gulf of Guinea and the Horn of Africa.

 

However, geopolitical tensions increase the likelihood of piracy and smuggling as countries shift trade routes away from sanctioned nations or areas of conflict.

 

For example, when the United States imposed sanctions on Iran, it prompted shipping companies to reroute ships away from Iranian waters.

 

This created a surge in piracy and smuggling activities in the Persian Gulf, as pirates attempted to take advantage of the reduced naval presence in the area.

Ship Store Bonded Provisions Logistics Maritime

– Imposition of Sanctions

Furthermore, geopolitical tensions can also result in the imposition of sanctions.

 

Sanctions against countries or entities can restrict trade and impact the movement of goods across borders. This can have unintended consequences for the shipping industry.

 

For instance, when the United States imposed sanctions against Venezuela, it resulted in a reduction in the number of ships traveling to the country due to the increased risk of penalties.

 

Consequently, shipping companies faced a significant decline in revenue, and many chose to withdraw from trading with Venezuela altogether.

 

The Good Part…

In addition to these challenges, geopolitical tensions can also create opportunities for the maritime industry.

 

Changes in trade routes and port preferences can create new business opportunities for ports and shipping companies.

 

The United States-China trade war prompted some companies to shift production to other countries and regions such as Vietnam, Thailand, and Indonesia.

 

This resulted in an increase of shipping traffic in the South China Sea and Southeast Asia, providing new business opportunities for ports and shipping companies in the region.

 

Similarly, political tensions in the Middle East can lead to increased demand for naval security services in the region, creating new business opportunities for shipping companies and security service providers.

 

In Conclusion

Geopolitical tensions can have both positive and negative impacts on the maritime industry.

 

While tensions can disrupt trade and increase the risk of piracy and smuggling, they can also create opportunities for ports and shipping companies.

 

Companies in the maritime industry must stay alert to the constantly changing geopolitical landscape and be nimble enough to adapt to new opportunities and challenges.

The use of these fossil fuels has become unsustainable, as they are not only finite resources but also contribute significantly to the emissions of greenhouse gases, which are responsible for climate change.

 

The Alternatives

Efforts to reduce greenhouse gas emissions have led the industry to explore other options, including alternative and renewable energy sources. Among these alternatives are biofuels, liquefied natural gas (LNG), and hydrogen.

1. Biofuels

Biofuels are derived from organic matter such as waste oils, animal fats or plant matter. They are considered renewable energy sources because they can be produced much faster than fossil fuels.


Biofuels have significant setbacks including the competition they create with food production and the potential environmental damage caused by intensive farming. As a result, they are not considered a long-term solution towards sustainable marine fuels.


2. Liquefied Natural Gas

Liquefied natural gas (LNG) is considered one of the most viable alternative fuels for the maritime industry. It is a clean energy source that produces fewer emissions of pollutants and greenhouse gases than fossil fuels.


However, there are also challenges associated with using LNG. One of these challenges is the high cost of conversion for existing vessels. Additionally, there is a lack of infrastructure for the production, storage, and transport of LNG.


3. Hydrogen

Another alternative that has been explored for marine fuels is hydrogen. Hydrogen is considered the cleanest fuel option, as it produces only water vapor as a byproduct. The production and distribution of hydrogen also create relatively low levels of greenhouse gas emissions.


However, hydrogen production is both expensive and energy-intensive, and significant infrastructure development is required for its storage and distribution.


In recent times, new innovations in the prospects of marine fuels in the future have shown a lot of promise. For instance, companies are beginning to develop synthetic fuels which can be produced using renewable energy sources such as wind and solar.
