The Importance of Monitoring Wash Water for Scrubbers

03.02.2023

Excerpt: The importance of monitoring wash water for scrubbers cannot be understated. It is clearly crucial for shipowners that they take the best option for their vessels and operations to ensure compliance with the regulations. For those considering making the investment in scrubbers, they will need to fully understand both the regulatory and operational implications and will actively seek reassurance that making the investment to install a system will result in compliance with all applicable regulations. For scrubber manufacturers, the onus is on them to provide reliable proof that their systems are fit for purpose and will not create further regulatory complications for their customers. It is only though accurate monitoring that both of these criteria can be met. Importance ofRead more

Compliance Testing on Sea Vessels

15.12.2022

Excerpt: The IMO was established following agreement at a UN conference held in Geneva in 1948 and came into existence ten years later, meeting for the first time in 1959. Headquartered in London, United Kingdom, IMO currently has 175 Member States and three Associate Members. Amongst other regulatory responsibilities, the IMO also has responsibility the prevention of marine and atmospheric pollution by ships and for the prevention of invasive species in ballast water. Wash water compliance On January 1st, 2020, a new IMO compliance limit on the sulphur content (SOx) in the fuel oil used onboard ships came into force.

Oil Spill Detection

12.09.2022

Excerpt: Oil spills threaten millions of miles of coastline, river systems, lakes, and terrestrial habitat daily, particularly where extensive oil drilling, refining, and transport take place, and the challenge of managing such oil spills around the world is only increasing in complexity and magnitude. Oil spills from tankers have some of the greatest adverse effects on the environment, since the oil would not have time to disperse before reaching shore and can significantly impact sensitive habitats. Oil spills and the environment The Deepwater Horizon oil spill is considered to be the largest oil spill in the industry’s history, creating extensive damage to the marine environment. According to estimates, this single spill killed over 82,000 birds, 25,900 marine mammals, 6,000 sea turtlesRead more

Fuel & Water Pollution

07.06.2022

Excerpt: It is against the law to cause pollution and for the last five years, fuels have consistently been among the UK’s top three pollutants. This means that any fuel spill or leak needs serious and imminent attention. Just one litre of oil is enough to contaminate one million litres of water, putting human life, wildlife and vegetation at severe risk. Depending on the density of the oil, it will either float, semi-submerge or sink in river, lake or stream water. The same oil, however, may have a different reaction when in seawater as the salt changes the density of the water. Oil leaks and spills are tightly monitored in the UK and polluters run the risk of running foul ofRead more

Detecting BTEX in Groundwater

07.06.2022

Excerpt: How do BTEX compounds enter groundwater? BTEX can contaminate natural waters through leaks in underground pipes, spills, improper disposal or leaching from landfills. As these chemical compounds are known to cause serious health effects to humans and pose a risk if exposed, a maximum contaminant level of 5 µg/L Benzene was established by the US EPA for drinking water to ensure removal from groundwater and surface water sources. Measurement is also commonly required for industrial manufacturers discharging petroleum contaminated water to municipal wastewater treatment plants. When gasoline is in contact with water, BTEX compounds account for as much as 90% of the gasoline components that are found in the water-soluble fraction. Consequently, these chemicals are some of the most commonRead more

UN Global Goal 3 & The Tryptophan Breakthrough

10.01.2022

Excerpt: What is UN Sustainable Development Goal 3? In the fine words of the UN declaration, ‘By 2030, substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water and soil pollution and contamination.’ Inadequate and unsafe drinking water, sanitation and hygiene is linked to 60 per cent of the disease burden from diarrhoea. UN Goal 3 is one of 17 Sustainable Development Goals established by the United Nations General Assembly in 2015. UN Global Goal 3 (SDG 3 or Global Goal 3) concerns itself with basic human health.

Marine Air Pollution: Scrubber manufacturers take on maritime GHG emissions, by Craig Jallal

05.01.2021

Excerpt: Scrubber experts relayed their experience of retrofit installation, wastewater monitoring and lowering the closed-loop scrubber carbon footprint during the Marine Air Pollution, Europe conference during a session sponsored by Yara Marine Technologies. During the session, Chelsea's Matthew Kenney tackled the topic of wash water monitoring. Chelsea Technologies is the provider of the Sea Sentry IMO-compliant wash water monitoring system. He noted that around 80% of scrubbers in use are open loop, meaning that seawater is pumped into the gas desulphurisation unit and back out to sea. “The whole issue of waste water is poised to be a more pressing issue throughout 2021,” he said. “This is because the rules have not been set and Wash water rules are sitting in the awkward guidelines space as an annex to the main regulations.” Read more

Being sure about ballast water compliance

21.10.2020

Excerpt: Shipping companies have a degree of responsibility over ballast water compliance and whether they actually manage to remove organisms from ballast water before discharging. How can this be best done? Tanker Operator magazine spoke to Chelsea Technologies. Just buying and installing a type approved ballast water system may not be enough to guarantee regulatory compliance, says Matt Kenney, head of marketing with Chelsea Technologies, a UK specialist in sensor design and manufacture. Shipping companies have a degree of responsibility over whether the ballast water they discharge contains organisms above the allowed limit. In most maritime state legislatures, ship operators are deemed accountable for “knowing” that they discharged pollutants into territorial waters. In the US, ship operators can be prosecuted forRead more

Accurate scrubber wash water monitoring – a necessary investment for future compliance

23.09.2020

Excerpt: Accurate scrubber wash water monitoring is a necessary investment for future compliance. The implementation of the International Maritime Organisation’s (IMO) 0.5% sulphur cap is set to be the first of many new environmental regulations over the coming years. Introduced to reduce the shipping industry’s impact on the heath and wellbeing of seafarers, and coastal communities, there is still some uncertainty about future regulation. With this in mind, ship owners and operators need to ensure that they are making careful and considered decisions in relation to the future design of their vessels, if they are to comply with future regulation, while also protecting investments. It is critical for both those who have already invested in scrubbers as a route to IMO2020Read more

Protecting shipowners in the long run: A case for stringent scrubber wash water monitoring

06.07.2020

Excerpt: Installing a scrubber represents a significant investment for a shipowner. With the financial cost of the system and its installation, coupled with the lay-up time – no shipowner can take the decision lightly; with the reduced spread between HSFO and VLSFO increasing pay back times, scrubbers need to make sense as an even longer-term investment today. The economic case for scrubbers remains strong, though. If HSFO remains cheaper than VLSFO, scrubbers will represent a return on investment for shipowners and the current gap is highly likely to increase rather than decrease any further. Then there is the issue of fuel availability, which is another key reason many scrubber-equipped vessels demand charter rate premiums. Due to the nature of HSFO asRead more

Enabling a future for shipowners; a case for stringent scrubber wash water monitoring

18.06.2020

Excerpt: ‘How do I help vessel owners ensure that they are making a choice that is future proof?’ article by Emma Johnson Investments can be precarious in the current climate. Therefore, all steps must be taken to validate any recommendations for compliance solution to shipowners to enable peace of mind and safeguard operations. In the case of scrubbers, it is imperative that shipowners have an in-built capability to allow them to monitor and manage wash water, providing assurance, but also – vitally – a tangible resource for regulators, as well as insurers, charterers and financiers. To stay afloat in 21st century shipping means always being one step ahead of the curve. Read more

Effective Ballast Water Monitoring in 3 Easy Steps

01.06.2020

Excerpt: The International Convention for the Control and Management of Ships’ Ballast Water and Sediments (2004) – herein referred to as the ‘BW Convention’ – is now an integrated part of operating a modern shipping fleet. Since 2017, all compliant ships have been employing a certified ballast water management plan, and any applicable vessels not yet fitted with a suitable ballast water treatment system should now be scheduled to install one before the next International Oil Pollution Prevention (IOPP) survey. By 2024, every vessel engaged on international voyages and fitted with a sea water ballast system should be in compliance with the ‘D-2’ standard for Ballast Water treatment, relegating the ‘D-1’ standard for ballast water exchange to a contingency measure, shouldRead more
