Finding proprietors happy to pilot-test an onboard remotely-operated positive hull cleansing system had not been simple, yet when Jotun connected to Wallenius Wilhelmsen, they located a companion that shared their vision for an extra environmentally-responsible delivery market.
As the driver of a fleet of 126 RoRo vessels, 11 aquatic terminals as well as 71 handling centres all over the world, Wallenius Wilhelmsen is a real international titan. And while the firm has a lengthy as well as happy background relocating freights throughout the globe, Wallenius Wilhelmsen has actually additionally been a leader in looking for brand-new methods to lower its ecological effect.
Holistic method
For the previous years, the firm has actually created a yearly Sustainability Report, explaining campaigns taken on to lower the firm’s discharges as well as protect life listed below the water line, to name a few target locations. According to Geir Fagerheim, SVP Marine Operations for Wallenius Wilhelmsen, the firm has an all natural method to minimizing discharges that consists of whatever from weather condition directing to engine optimization, hull finishes to advanced hydrodynamic hull, tail as well as prop layout.

“In 2019, the company achieved a 11 per cent reduction in CO2 emissions from the year before, due in part to technical improvements,” he states. Fagerheim includes that Wallenius Wilhelmsen has actually additionally signed up with the “Getting to Zero Coalition”, a partnership of greater than 90 business throughout the maritime, power, framework as well as money markets, which are interacting to establish readily feasible no discharge vessels by 2030.
“Achieving zero emission vessels won’t be easy, but we recognise that by taking a collaborative approach to common challenges, we can accelerate the development of technologies that can make a difference,” statesFagerheim “Jotun Hull Skating Solutions certainly fits that description.”
Embracing brand-new modern technologies
Jotun Hull Skating Solutions contains 5 remedy parts; A high efficiency antifouling covering SeaQuantum Skate, positive problem surveillance, evaluation as well as positive cleansing with sophisticated undersea robot Jotun HullSkater, premium technological solution as well as efficiency as well as solution degree warranties that fit one of the most difficult procedures. In 2016, Jotun come close to Wallenius Wilhelmsen to pilot-test the system aboard among their vessels.

Fagerheim recognizes that some at Wallenius Wilhelmsen were skeptical initially. “The concept is a radically new approach to hull maintenance so our team had a lot of questions,” statesFagerheim “However, once we learned that Jotun had developed a prototype in cooperation with KONGSBERG and the Swedish technology company Semcon among other partners, we decided to participate.”
Fagerheim keeps in mind that unlike a lot of hull cleaning company, Hull Skating Solutions (HSS) is positive, not responsive. “By removing slime and fouling before organisms have time to firmly attach to the hull, HSS not only helps owners reduce fuel costs and corresponding emissions, it helps vessels stay in compliance with increasingly strict local and global regulations designed to protect marine ecosystems from alien invasive species,” he states. “The benefits of Jotun Hull Skating Solutions align perfectly with our business strategy and sustainability goals.”
Pilot screening
In 2017, Wallenius Wilhelmsen offered the HSS group accessibility to the Talisman, a DWT 38500 RoRo provider constructed in 2000. Geir Axel Oftedahl, Jotun’s Business Development Director (Marine), discusses that unlike responsive hull cleaning company used at lots of ports, proprietors mount the Hull Skater aboard. “High powered magnets attach the unit to the hull, allowing it to perform underwater inspections and proactive cleaning using HD cameras and a specially designed brush that does not damage the antifouling coating or release biocides into the water,” he discusses.

The HSS Project Team used antifouling examination spots on the hull, mounted the system aboard as well as offered training for team participants on upkeep, release, access as well as storage space of the system. Once undersea, the system is from another location regulated. “We can operate HullSkater units all over the world from our control centre here in Norway, day and night,” statesOftedahl “We learned that depending on the size of the vessel, cleaning and inspection can take between 2-8 hours.”
Oftedahl keeps in mind that the firm’s multi-year pilot examination with Wallenius Wilhelmsen (as well as various other proprietors, consisting of Berge Bulk as well as Maersk) offered the job group with beneficial understanding on what functioned– as well as what really did not. “In addition to providing us the opportunity to test the unit under different operational conditions, Wallenius Wilhelmsen was also instrumental in helping us reach out to port authorities to ensure we could operate in compliance with local regulations,” states Oftedahl.
Port authorities
Over the previous 2 years, HSS has actually been effectively pilot-tested on vessels in various ports all over the world. Today, Jotun is functioning to develop arrangements with some ports which need documents of a tidy undersea hull before port telephone call. “Because HSS is a new technology, no uniform standards currently exist,” statesOftedahl “Our relationship with our pilot partners has been enormously helpful in working through these issues.”
Fagerheim recognizes that minimizing shelter prices, fulfilling the progressively stringent needs of freight proprietors as well as abiding by policies on discharges as well as unusual intrusive varieties are all powerful motorists for proprietors to boost vessel performance as well as ecological efficiency. But by being positive as well as operating in cooperation with providers, he thinks the market can attain far better outcomes, much faster. “As we have seen with Jotun Hull Skating Solutions, a project that involved a broad range of stakeholders, collaboration can produce some game-changing technologies that get us one step closer to a more environmentally responsible industry.”
