A robotic system intended to clean litter from the seafloor has passed its first real-life tests in waters near Dubrovnik, Croatia. The cleaning system, which works similarly to home robot vacuums, was able to see waste on the bottom of the sea and move towards it. A plastic bottle became the first official litter to be picked up from the seabed. This series of tests is a small step in humanity’s goal of cost-effectively cleaning the seafloor, where more than 90% of the sea garbage is found.

The waste clearing system consists of underwater robots, a surface vessel and drones workinf together. First, the underwater robots and the drones use sensor data and artificial intelligence to locate and identify litter on the seafloor. When litter is detected, an underwater robot equipped with a gripper is sent to collect the waste. The system has been in development for the past two years by the European-funded SeaClear project (SEarch, identificAtion and Collection of marine Litter with Autonomous Robots) that joins together researchers and industry from five countries.

This October, three key components of the system were tested in a real water environment: the underwater inspection robot, a gripper prototype, and an aerial drone. “We went to a tourist area in Croatia, Lokrum Island near Dubrovnik, which is one of the first places we want to clean once the SeaClear system is fully operational”, says professor Bart De Schutter, from Delft University of Technology, the Netherlands, who leads the project. “The main star of the test was the underwater inspection robot. We wanted to see whether it’s able to detect and move towards the litter in various water conditions”, explains De Schutter.

The first live test resulted in the first official litter being picked up from the water by the SeaClear robot: a plastic bottle! This happened during the test at a second location, also close to Dubrovnik, Croatia, but with less clear water. The team tested a 3D printed prototype of its newly designed gripper, to identify weak spots in the design and operation under real-life conditions and indeed, it broke. However, to have a proof-of-concept, the researchers were able to repurpose an existing, sturdier gripper, and managed to successfully pick up litter underwater.

The test was also important for the software part of the project. “The concept is simple on paper and not unlike our home robot vacuum cleaners”, says professor Lucian Bușoniu, from Technical University Cluj, Romania, who is leading the litter-search part of the project. “However, the complexity of robot positioning and control, as well as of litter identification and collection, is much higher and makes the objectives much more difficult to achieve. We wanted to test out our concept and we now need to go through all the data sets from our cameras, the sonar and the robot positioning sensors. This will help improve our software.”

A completely autonomous robotic system for sea litter cleaning would be a vital and cheap solution to one of the largest environmental problems our planet is facing. Today’s oceans contain 26-66 million tons of waste, such as pieces of plastic, bottles or tyres. The waste that we see at the surface represents a mere 6% of the total, the rest is resting at the bottom. Tourist resorts and port authorities currently resort to divers to clean up this waste from the seabed, sometimes at the cost of their safety.

“For example, in September 2020, a human-only marine litter clean-up that took place in the same test area close to Lokrum Island, resulted in 17 divers collecting more than 88 kg of waste from the seafloor in a one-hour period”, said Iva Pozniak, principal investigator for Regional Agency Dunea, Croatia. When completed, the SeaClear system should achieve similar results with minimal human intervention.

SeaClear is a European Horizon 2020 project that was launched on 1 January 2020. It runs until December 2023. The total budget is approximately EUR 5 million. There are eight partners from five countries and 49 researchers involved.

The eight partners are: TU Delft, Hamburg Port Authority, TU Cluj-Napoca, Subsea Tech, TU Munich, Fraunhofer CML, University of Dubrovnik and DUNEA.

The Global Centre for Maritime Decarbonisation GCMD and MOL announced the signing of a five-year Impact Partnership agreement. On the same day, both parties held a signing ceremony at the GCMD office in Singapore.

Decarbonisation in the maritime industry is a challenge that needs to be achieved through accelerating collaboration and increasing investment by shipping companies, their customers, ports, energy suppliers and public sector actors. As an Impact Partner of GCMD, MOL will utilise its expertise developed over their long history and make various contributions and collaborations through its participation in GCMD’s projects, including providing access to vessels, operating data and evaluation reports so that internal learnings can be shared publicly and used for future trials.

MOL is one of the world’s leaders in the maritime industry and has been leading worldwide discussions on achieving decarbonisation. The carbon budget concept imposes a ceiling to the cumulative amount of greenhouse gas (GHG) that can be emitted globally in order to limit global temperature rise to 1.5 degree Celsius by 2050. Intermediate targets to reduce emissions, in addition to a net-zero target, are necessary. While plans are in place to adopt low or zero emissions vessels in the future, it is important to deploy measures to reduce emissions now. Such measures include the use of low-carbon and transition fuels that are available today, and deploying energy savings devices onboard vessels. MOL will bring its extensive capabilities and experience to bear as it joins GCMD and existing partners to accelerate international shipping’s decarbonisation.

Professor Lynn Loo, CEO of the Global Centre for Maritime Decarbonisation, said: “We are proud to have MOL, one of the leading shipowners in Japan, come onboard as an Impact Partner. We are excited to tap on MOL’s track record in developing technical energy efficiency measures to broaden our perspective as we scope an initiative to help increase industry adoption of measures that can increase fuel efficiency of ships.”

Toshiaki Tanaka, Representative Director, Executive Vice President Executive Officer, and Chief Operating Officer of MOL, said: “We are very pleased to be a partner of one of the most important global coalitions. We will make our biggest effort to contribute and accelerate progress towards the net zero future in maritime industry, together with GCMD and all its partners.”

About the Global Centre for Maritime Decarbonisation

The Global Centre for Maritime Decarbonisation (GCMD) was set up on 1 August 2021 as a non-profit organisation. Our strategic partners include the Maritime and Port Authority of Singapore (MPA), BHP, BW Group, Eastern Pacific Shipping, Foundation Det Norske Veritas, Ocean Network Express, Seatrium, bp, Hapag-Lloyd and NYK. Beyond the strategic partners, GCMD has brought on board 15 partners that engage at the centre level, in addition to more than 80 partners that engage at the project level.

Hapag-Lloyd has entered into a partnership with DB Schenker for the purpose of decarbonising supply chains. Following the launch of “Ship Green” in May, the renowned logistics provider has selected Hapag-Lloyd’s sustainable transport solution as part of its sustainability initiatives.

DB Schenker and Hapag-Lloyd have signed an agreement for emission-reduced container transports with a waste- and residue-based biofuel. By end of 2023, DB Schenker plans to claim approximately 3,000 metric tonnes of carbon dioxide equivalent (CO2e) emissions avoidance. This is based on at least 1,000 tonnes of pure biofuel.

“We are excited about this new partnership with DB Schenker as we share the common goal of making logistics more sustainable. Collaborations like these set a clear signal in the industry and are another example of a step-by-step approach to further decarbonise supply chains”, said Henrik Schilling, Managing Director Global Commercial Development at Hapag-Lloyd.

“I am very pleased that together with Hapag-Lloyd we are setting another example for sustainability in our industry. This partnership further enlarges our global biofuel offer in ocean freight. With this commitment we are one step closer to our goal of becoming carbon-neutral”, said Thorsten Meincke, Global Board Member for Air & Ocean Freight at DB Schenker.

Hapag-Lloyd has launched the Ship Green product to offer its customers emission-reduced ocean transports. Based on biofuel, customers of Hapag-Lloyd can add Ship Green as an additional service to their existing bookings – thereby avoiding CO2e emissions. Using the so-called “Book & Claim” chain of custody, Hapag-Lloyd can attribute avoided emissions to all ocean-leg transports, regardless of the vessel and route used. Ship Green is available for all shipments containing standard, hardtop or tank equipment. By offering Ship Green, Hapag-Lloyd is continuing along its path towards achieving climate-neutral fleet operations by 2045.

EU Member States cleared the way to bring sustainable renewable fuels into maritime transport. They approved the “FuelEU Maritime” regulation. The EU Parliament had also voted in favour of the agreement reached in the trilogue procedure.

The new requirements will apply to ships with a gross tonnage of more than 5,000 entering, leaving or staying in ports in the territory of an EU Member State. In addition, shore-side electricity will be mandatory for container and passenger ships from 2030. The use of synthetic fuels from renewable energies will be specifically promoted for shipping.

Federal Minister of Transport Dr Volker Wissing:
After we were recently able to achieve a breakthrough for maritime climate protection at UN level, we are now pushing the actual transformation towards climate-neutral shipping at European level with the “FuelEU Maritime” initiative. The draft regulation is open to technology and takes into account the special competitive conditions in the maritime transport sector. The main objective is to increase the demand for renewable and low-carbon fuels and their consistent use, thereby decisively reducing greenhouse gas emissions in maritime transport. The initiative is thus expected to play a fundamental role in the implementation of the European Climate Change Act for shipping.

Federal Environment Minister Steffi Lemke:
Today the EU has set a decisive course for more climate protection and the use of renewable fuels in maritime transport. Shipping companies will continue to rely on fuels in the future, because electric drives are not yet an option for long-distance transport. In maritime transport, e-fuels from renewable energies are therefore a sensible climate-friendly alternative. With the new requirements, the EU is giving manufacturers and shipping companies the necessary planning security, driving forward the development of modern technologies and making renewable fuels for maritime transport ready for the market. But there are also shadows: The fact that fuels from fossil sources and nuclear energy are also permitted as a compliance option is regrettable. The German Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV) will continue to advocate the use of predominantly synthetic fuels from renewable energy sources in order to make maritime transport climate neutral.

FuelEU Maritime lays down uniform EU-wide rules for limiting the greenhouse gas intensity of the energy used on board a ship, and thus above all the fuels. The regulation from the Fit for 55 package stipulates that shipping in the EU must reduce its emissions by 2 percent from 2025, 6 percent from 2030, 14.5 percent from 2035, 31 percent from 2040, 62 percent from 2045 and 80 percent from 2050. The GHG intensity reduction targets are set against the 2020 average GHG intensity of energy consumed on board ships. The greenhouse gas emissions of all fuels are assessed on the basis of a life cycle assessment (so-called well-to-wake (WtW) approach that includes the greenhouse gases carbon dioxide, methane and nitrous oxide). All fuels are permitted as a compliance option; the legislative initiative is thus technology-neutral.

The use of synthetic fuels is encouraged by a special mechanism: if the share of synthetic fuels from renewable energy sources (so-called “renewable fuels of non-biological origin, RFNBO) in the fuel mix does not exceed one percent in 2031, a mandatory minimum quota of two percent for these RFNBO fuels will automatically come into force from 2034. Beyond the use of alternative fuels, the FuelEU Maritime Regulation obliges container and passenger ships in ports in the territory of a Member State to use shore-side electricity or alternatively zero-emission technologies for on-board energy supply.

This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union. It shall apply from 1 January 2025, with the exception of certain Articles which shall apply from 31 August 2024.
