Two globally renowned companies in marine electrification, Volvo Penta and Danfoss’ Editron division, have worked together to power two of the United Kingdom’s first fully integrated hybrid electric crew transfer vessels (CTVs).

The two fully integrated hybrid electric crew transfer vessels (CTVs) have been in operation at an offshore wind farm, for a month and are already making a positive environmental impact.

A recent announcement from COP26 was the promise of £160 million in new funding, to support the building of floating offshore wind farms, in Scotland and Wales, in the United Kingdom. Although this is a significant win in the UK government’s commitment to quadruple offshore wind farm capacity, to 40 gigawatts, by 2030.

It also means that more CTVs will be needed to deliver supplies and transport workers, to the offshore sites and so reinforcing efforts, such as the Global Offshore Wind Alliance and other such creditable initiatives, to come out of COP26 will be vital.

vessels powered by Volvo Penta and Danfoss’ technology

Wind farm transfer company, MHO-Co is meeting this growing demand for transportation between shore and wind farms, in the greenest and most economically viable way. The company recently took delivery of two new hybrid vessels, to service its offshore customer, Ørsted’s Hornsea Project 2 offshore wind farm, located in the North Sea. The two vessels - MHO Asgard and MHO Apollo, are powered by combined technology from Volvo Penta and Danfoss Editron.

Cross-industry collaboration is needed now more than ever, to take steps towards mitigating the negative impacts of climate change,” said Peter Granqvist, Chief Technology Officer, at Volvo Penta, adding “By working together, we’ve been able to begin to make real change with impressive fuel and emission savings, as well as more flexible operation for our customers.

The two-hybrid vessels have both been in operation for just over a month

The two-hybrid vessels have both been in operation for just over a month and have already logged over 330 engine hours between them in the field, as well as 1000 hours on their maiden voyage from China to the North Sea.

MHO Asgard and MHO Apollo vessels have ferried over 50 workers and numerous supplies to the Hornsea Two offshore wind farm, which is located approximately 89 km (55.3 miles) off the Yorkshire coast, in the United Kingdom.

Vessels equipped with Inboard Performance System (IPS)

The vessels, both equipped with Volvo Penta Inboard Performance System (IPS), have already had an impressive environmental impact, offering fuel savings of 20.89% and reducing CO2 emissions by 20.96%, when compared to non-hybrid vessels, without IPS, in MHO-Co’s fleet.

Another major advantage of the hybrid vessels is the multiple power systems onboard, which Danfoss Editron and Volvo Penta have dubbed ‘the Power of Plenty’.

Multiple power systems onboard

This new system gives us more flexibility and allows us to switch between engines and do maintenance, when it fits our schedule, without affecting the service to our customers,” explains Mik Henriksen, CEO of MHO-Co.

He adds, “We are also able to use just one small engine, when idling in the wind park, offering significant fuel saving and noise advantage, when in waiting position. I think we have the best system possible, with the technology that exists today.

Danfoss Editron and Volvo Penta partnership

Danfoss Editron and Volvo Penta are offering a completely unique solution

Through their collaboration, Danfoss Editron and Volvo Penta are offering a completely unique solution, to the offshore wind industry.

By working closely together on the design, build and delivery of the vessels, the two companies have been able to provide a solution that allows the vessels to operate in zero-emissions electric mode, for up to eight hours, or combined with fuel propulsion, to achieve a maximum speed of approximately 24 knots.

Marine electrified propulsion solution

In these hybrid crew transfer vessels, we are addressing marine electrified propulsion with one total system solution,” said Peter Granqvist.

We’re proud to have pushed the limits of technology with Volvo Penta. MHO-Co now has access to the best technology and services from two of the leading companies that are offering marine electrification solutions to the global market,” said Kimmo Rauma, Vice President, Editron division, at Danfoss.

Running a tight ship on port security around the UK
Running a tight ship on port security around the UK

Ports around the UK continuously command media attention, and most recently, the ongoing disruption to supply chains globally has had a great impact on the day-to-day running of our ports. One example is Felixstowe, the UK’s largest container port, which has been forced to turn away ships from Asia because of a lack of capacity. The severe lack of HGV drivers is adding to the problem too. It has been reported that the amount of time goods spend inside Felixstowe port, known in the industry as ‘dwell time’, has doubled since last year from 4.5 days to 9. High-gain strategy There are plans in play to increase the number of ports in the country in the coming years. This was unveiled in the March 2021 Budget, where according to Chancellor Rishi Sunak, sites including Liverpool and Hull are becoming special economic zones, expected to ‘exemplify the future economy.’ Maritime freight cargo theft continues to be a low-risk, high-gain strategy for organised crime gangs Despite more than 90% of the world’s goods being shipped by sea, maritime freight cargo theft continues to be a low-risk, high-gain strategy for organised crime gangs. Reported thefts are on the rise, with criminals responding and changing their behaviour to adapt to COVID lockdown measures. More recently, ‘hook up’ thefts, whereby perpetrators steal entire loaded trailers from premises have been taking place, underlining the need for physical barriers to protect goods and assets. Harsh coastal environment There’s an urgent need to ensure the perimeter security selected to protect these ports from opportunistic criminals is robust enough to deter attack, and also withstand the inevitable wear and tear that the exposure to the harsh coastal environment will cause. Safety and security issues need to be carefully managed to protect property, cargo, and lives at sites where shipping delays are commonplace. While there are measures in place to ensure security at ports, more needs to be done to provide adequate levels, to keep pace with upcoming growth plans. Specifying robust security measures for maritime sites can be challenging - keep reading for our key considerations. Perimeter security projects The best suppliers will advise on what’s needed to meet certain standards As with all perimeter security projects, the process should begin with a thorough assessment of the site. This will flag important considerations including the choice of aesthetic and will help decipher the best suited security barriers for the site. Make a conscious effort to ensure you’re meeting the safety and sustainability compliance requirements. The best suppliers will advise on what’s needed to meet certain standards, so if in doubt, ask the experts. Next, consider the lifetime value of the specified products. Opting for durable and high quality materials will guarantee longevity, and help mitigate budgetary cost pressures later down the line. For ports and coastal environments, marine coatings are worth investigating. These will have been specifically designed to provide a long lasting, tough coating for exterior applications. Typical airborne pollutants In addition to being more durable in adverse weather conditions and salt spray, the marine coat is also resistant to stress cracking, detergents, and typical airborne pollutants. These properties ensure excellent adhesion to the metal substrate without the need for a separate primer. Whatever the application, marine coat has undergone long-term field tests to prove that it can provide: A long life with superior corrosion and abrasion protection. Excellent grip, feel, and electrical insulation. Resistance to chipping and attack from light, pollutants, chemicals, and vandals. An attractive, environmentally friendly finish. It is also worth doing your research and looking into more innovative products on the market. Tamper-proof panel connectors with fixings on the secure side of the fence provide a simple solution for securing mesh panels to posts that is often overlooked. Piezoelectric sensor cable PIDS are a discreet security measure and are ideal when used as part of an integrated security strategy One project we worked on recently in this industry was for Tilbury, here a fence-mounted Perimeter Intrusion Detection System (PIDS) was specified and consisted of a piezoelectric sensor cable. This is attached to the fence, and detects attempts to cut, climb, or vandalise the system, sending audible signals and vibrations to a seismic analyser. It has exceeded the required standards for tests by UK Home Office and other Government tests for reliability, false alarms, and detection, and is approved for use on CNI and HM Prison sites. The Jaktronic PIDS can be installed on most types of security fencing, including chain link, welded mesh, and vertical bar railings, to provide early warning of any intrusion attempt. The system also has no topographical limitations. PIDS are a discreet security measure and are ideal when used as part of an integrated security strategy as a highly reliable form of detection. Combining perimeter fencing Investing in the longevity of the chosen security fencing will also save money on costly repairs and deterioration in the long term. Ongoing maintenance of fencing and gates must be regular and thorough, particularly in maritime environments. Ongoing maintenance of fencing and gates must be regular and thorough We often refer to an integrated approach to security, and combining perimeter fencing with additional surveillance and alarm technology where required will help achieve this. Systems combining security fencing with CCTV cameras, and anti-intrusion detection alarms and monitors are recommended to provide a secure holistic perimeter security solution. Robust security measures Perimeter fencing will only ever enhance a security strategy, and when specified correctly, alongside electronic security systems, it will create a robust level of physical protection, making the site far less appealing to intruders. Consulting with manufacturers will aid a full understanding of the available solutions. We advise investing time in making use of suppliers’ website information, product videos, NBS Source, and expert advice. With valuable and essential goods passing through our ports daily, robust security measures must be installed. This will help to ensure the facilities continue to run smoothly and reduce delays.

Backlogged ports among symptoms of global supply chain disruption
Backlogged ports among symptoms of global supply chain disruption

Backlogged ports, a shortage of shipping containers and not enough workers are among the factors contributing to supply chain disruptions that have led to shortages of various goods and are likely to impact availability of merchandise, during the upcoming holiday season. Demand is growing rapidly as the impacts of the COVID-19 global pandemic have diminished. However, lingering consequences of the pandemic are continuing to impact the container shipping market. With each element in the system tightly intertwined, any changes tend to ripple with additional repercussions. Slow circulatory movement of containers A direct upshot of the COVID-19 pandemic was to slow the circulatory movement of containers globally. To increase productivity and save time, some vessels began making their return journeys empty, in effect leaving more empty containers at the delivery destination and fewer at the source of shipments. The varied timing of the pandemic in Asia and the West compounded the problem At one point, Asian containers could not be sent back to Asia, because of COVID-19 restrictions in place. The varied timing of the pandemic in Asia and the West compounded the problem. With empty containers stacking up in the West and a shortage in the East, slower circulation of containers and higher demand have led to sharp increases in costs. Millions of TEU dry container units added A lack of new equipment is not the problem. Last year, the industry added about 2.8 million twenty-foot equivalent (TEU) units of dry containers, in line with the 10-year average. Congestion at ports has been going on for months and still continues. Recently, in the San Pedro Bay region, near the Port of Long Beach, in California, there were 144 ships, including 85 ships that were waiting to unload. In Savannah, Georgia, more than 20 container ships were waiting to dock. Ports in the US states of New Jersey, New York and Texas have also seen record backlogs. Majority of influential global ports face backlogs According to one report, 77% of the most influential ports in the world reported above-average wait times this year. The turn-around time for a container in ports has nearly doubled in 2021, in comparison to 2019. A worker shortage at the ports is aggravating the problem and container ships now carry about 30% more goods, which require more labour to unload. Ports are also doing the additional work with fewer people. There is also reduced labour productivity at warehouses and marine terminals. Investment in workforce training to counter bottlenecks Some port bosses expect the bottlenecks to last through the summer of 2022. To address the problem, some ports are investing in workforce training and scheduling night-time appointments to pick up goods. Although a lot of attention is focused on the ports, they are just one element in the troubled supply chain. Even if the ports could increase their capacity, downstream processes would also have to increase their labour force, to accommodate the higher volume. Difficult to absorb impact of global supply chain disruptions In the best of times, the global supply chain operates like a well-oiled machine In the best of times, the global supply chain operates like a well-oiled machine, despite its complexity and the inter-relatedness of various stakeholders. However, the sheer size of the system makes it difficult to absorb the impact of any disruptions. Turning the system around takes time, and a burgeoning global demand for goods, in the aftermath of a global pandemic, makes recovery even more difficult. The Biden Administration in the U.S. has established a Supply Chain Disruptions Task Force, to monitor and address short-term supply issues. This task force is convening meetings of stakeholders in industries with urgent supply-chain problems, such as construction and semiconductors, to identify the immediate bottlenecks, as well as potential solutions. Role of global supply chain more critical now There have been supply chain disruption and staff shortages in several countries, including the United Kingdom (UK), Germany and New Zealand, according to business surveys. As the economy recovered and demand increased, businesses have not yet been able to bring inventories fully back to pre-pandemic levels, causing inventory-to-sales ratios to fall. The role of the global supply chain has never been more critical.

How the maritime industry is working to lower carbon emissions
How the maritime industry is working to lower carbon emissions

The maritime industry is not covered by the Paris climate agreement, which seeks to limit global warming to well below 2 degrees Celsius compared to pre-industrial levels. However, carbon emissions from maritime activities account for 2 to 3% of total global warming potential (GWP) worldwide, and the share is likely to increase in coming years, approaching 17% of CO2 emissions by 2050. The International Maritime Organisation (IMO) and its Marine Environment Protection Committee (MEPC) is tasked with regulating carbon usage in the maritime industry and has established aggressive goals – both near-term and long-term – to ensure carbon emissions from the maritime market decrease by at least 40% in 2030 (compared to 2008 levels), and by at least 50% by 2050. MEPC has new emissions reduction and efficiency requirements taking effect in 2023. Measures to reduce carbon emissions Binding across its 170 member states, IMO has adopted mandatory measures to reduce emissions of greenhouse gases under its pollution prevention treaty (MARPOL). The Energy Efficiency Design Index (EEDI) is mandatory for new ships, and the Ship Energy Efficiency Management Plan (SEEMP) is required for all ships. The Sustainable Shipping Initiative (SSI) is a multi-stakeholder initiative to improve the sustainability of the shipping industry in terms of social, environmental, and economic impacts. Founded in September 2010, SSI has 15 members spanning the shipping value chain, from charterers, shipowners and operators, to shipyards, banks, classification societies, and technology companies. Poseidon Principles Poseidon Principles are consistent with efforts of the IMO to reduce shipping’s total annual greenhouse gas emissions The Poseidon Principles establish a framework for banks and financial institutions to assess and disclose the climate alignment of ships to provide guidance and promote responsible environmental stewardship. The Poseidon Principles, signed by 20 financial institutions representing over $150 billion in loans to the shipping industry, are consistent with efforts of the IMO, seeking to reduce shipping’s total annual greenhouse gas emissions by at least half by 2050. Decarbonisation goals Some shipping companies are already setting individual decarbonisation goals beyond the IMO’s target, driven by their customers’ desire to reduce their global carbon footprint. The intensity of emissions has decreased somewhat in recent years because of larger ship sizes and slower traveling speeds. Interim solutions to lower carbon emissions include the use of liquefied natural gas (LNG) as a shipping fuel, which produces less carbon than the oil commonly used. LNG can also be less expensive but is not seen as a permanent solution because it still emits carbon. FuelEU Maritime initiative Global maritime technology networks promote the adoption of low-carbon technologies The European Commission has launched the FuelEU Maritime initiative, seeking to increase the use of sustainable alternative fuels in European shipping and ports. The European Union also seeks to include the shipping industry in a mandatory cap-and-trade carbon market, a so-called emissions trading scheme, as early as 2022. Also, the global maritime technology network (GMN), funded by the European Union, is a network of Maritime Technology Cooperation Centres (MTCCs) in Africa, Asia, the Caribbean, Latin America, and the Pacific. They seek to develop national maritime energy-efficiency policies, promote the adoption of low-carbon technologies and establish voluntary pilot data collection and reporting. Carbon Intensity Indicator (CII) ratings Scope ESG Analysis, a German credit rating, and analysis firm has launched a database to display Carbon Intensity Indicator (CII) ratings for the world’s commercial maritime fleet. Including 70,000 vessels, the Ship Review database provides transparency into each ship’s environmental, sustainability, and reliability/safety performance.  The CII rating system seeks to assist the maritime industry in reducing greenhouse gas emissions, measuring a ship’s operational efficiency in grams of CO2 emitted per deadweight tonnage and nautical miles travelled. Based on 2020 data, more than a third of the world’s fleet could fail to meet upcoming restrictions. GreenVoyage2050 Project The International Maritime Organisation is executing the GreenVoyage2050 Project through the Project Coordination Unit (PCU). The project seeks to help developing countries in their efforts to reduce greenhouse gas (GHG) emissions from ships. Longer-term fixes to lower greenhouse gases include a need for zero-carbon fuels and technologies Phase one of the project, signed with Norway in 2019, is currently underway. Phase one of the GreenVoyage2050 Project is scheduled to run until May 2022. Longer-term fixes to lower greenhouse gases include a need for zero-carbon fuels and technologies; however, they are not currently available at the size, scale, or price the industry needs for broad adoption. New fuels will need to be developed, along with new propulsion systems, upgraded vessels, and a new global refueling network. Need for zero-emissions technologies New zero-emissions fuels and technologies on the horizon include batteries, sustainable biofuels, green or blue hydrogen, and their derivatives such as ammonia and methanol. Blue hydrogen is produced from natural gas by splitting molecules into hydrogen and carbon dioxide and capturing and storing the CO2. Green hydrogen is produced by splitting water through electrolysis and powering the process using renewable electricity sources such as wind and solar.  However, zero-carbon technologies are far more expensive than current bunker fuel oil. A wide variety of global stakeholders are involved in trying to lower the impact of maritime’s carbon emissions on climate change. The maritime industry’s 2 to 3% impact may seem small, but the share could increase over time unless the industry continues to take action.
