Jumbo Maritime - Experts & Thought Leaders

Jumbo is pleased to announce the successful installation of two mechanical sails to the Heavy Lift Vessel (HLV) Jumbo Jubilee. The wind-assisted ship propulsion (WASP) solution is the latest in a series of innovative technologies installed on the vessel in a bid to boost fuel efficiency and cut carbon.   Jumbo is committed to advancing sustainable heavy-lift shipping with innovative energy-saving and decarbonisation initiatives across its fleet, says Jumbo Maritime CEO Daan Kornneef.   Decarbonise and innovate “At Jumbo, we believe that every step towards sustainability is crucial. The installation of these mechanical sails on Jumbo Jubilee is a testament to our commitment to decarbonise and innovate." "While there’s always more work to be done, initiatives like this propel us closer to a greener maritime industry. We’re proud of our team’s continued efforts in making Jumbo a leader in sustainable shipping.”   Unique approach  The installation of two Econowind ventofoils will assess the impact of WASP on the vessel’s efficiency The company’s approach is to apply multiple fuel-saving solutions to a single vessel, thereby making possible the measurement of each technology’s contribution to the overall picture.  Examples already applied to Jumbo Jubilee include an efficiency-boosting propeller coating, an AI-powered anti-fouling monitoring system, and an eco-control system. This latest move, the installation of two Econowind ventofoils, will assess the impact of WASP on the vessel’s efficiency.  Winds of change  Jumbo Technical Manager Andres Cassanova explains, “While not fully optimised for our vessel type, these sails will help us to gather valuable insights on real-world fuel savings and explore further optimisations that will allow Jumbo to reduce its environmental footprint even more.”  The relatively small footprint of the sails makes them an ideal solution for installation on a heavy lift vessel, where space is required for project cargoes. Additionally, the sails are flexibly mounted on a customised frame engineered in-house by Jumbo structural engineer Estelle Bongers. With this, the sails can be moved, or even transferred to another vessel should additional space be required for cargo.   AI-powered anti-fouling monitoring  This innovative system captures a wide range of data including vessel speed, geographical position The installation of the ventofoils follows the application of an anti-fouling coating on the ship’s propeller to maintain efficiency, as well as the introduction of an AI-powered anti-fouling hull coating monitoring system.   This innovative system captures a wide range of data including vessel speed, geographical position, as well as seawater temperature, and other environmental conditions and parameters. Fuel efficiency This allows the system to make predictions and provide notifications when there is a risk of accelerated fouling.   This means that Jumbo can perform an inspection and undertake maintenance in advance of a decrease in fuel efficiency. It also means the system can be maintained using less aggressive methods, ensuring its preservation for longer durations between dockings.   ​Intelligent cruise control   A further measure is the installation of an eco-control system on the vessel A further measure is the installation of an eco-control system on the vessel. “This can be viewed as a type of intelligent cruise control,” explains Andres. “It allows us to set a fuel consumption or maximum speed limit. With this, the eco-control system takes over and, based on RPM and propeller pitch, is continually adjusting to ensure optimally efficient performance, minimal fuel consumption, and emissions.”  Sustainability from desk to deck  With these significant technologies installed on the Jumbo Jubilee, Jumbo expects to achieve fuel savings. A crucial factor in this, says Technical Superintendent Patrick Feddes, is collaboration. “If you want to reduce your environmental footprint, it’s not only down to one part of the company." "It’s a team effort between those on board the ships and those on shore. The technologies play an important supporting role in creating energy savings, but a significant factor is an awareness and cooperation throughout the various departments of the organisation.” Casanova, “It’s the years of technical expertise, in-house engineering, and strong teamwork that drives sustainable innovation from desk to deck.”  

Jumbo Offshore has completed its TP (transition piece) T&I (transport & installation scope) on the Yunlin Offshore Wind Farm (OWF) in Taiwan under a contract with Yunneng Wind Power Co., Ltd. For its role in the project, Jumbo Offshore deployed its DP2 Heavy Lift Crane Vessel Jumbo Javelin.  Reliable project execution  Before undertaking the project, Jumbo Offshore carried out extensive project preparations to ensure a smooth, reliable project execution. Following this, Jumbo Javelin was outfitted in a project-specific set-up. This included the Jumbo Fly-Jib modular crane boom extension.  This feature can be mounted on a Jumbo J-Class vessel to increase the lifting height. With this, the vessel was provided with the capability to lift the 27 m high TPs. Jumbo Javelin performed the final TP installation on Friday, August 23.  Proud safety record  The vessel was loaded out with TPs in Kaohsiung, transporting up to four 450t TPs at one time The vessel was loaded out with TPs in Kaohsiung, transporting up to four 450t TPs at one time. In total, Jumbo Javelin transported and installed 80 TPs during the project. Jumbo Offshore completed its scope ahead of schedule, contributing to the client's target of completing the OWF before the end of 2024 and maintaining an excellent QHSE record and safety culture during the project execution. Versatile execution  Water depths at the Yunlin OWF vary between 7 and 35m. The shallower water location is not suitable for installation in DP mode. Therefore, Jumbo Offshore switched between installation on DP and installation on anchors, making full use of the vessel's versatility.   The Yunlin OWF is located in the Taiwan Strait, between 8 and 17 km from the coast of Taiwan. Covering an area of 82km2, the OWF comprises 80 WTG (wind turbine generators), able to provide up to 640 MW of clean electricity, sufficient to power 600,000 Taiwanese households. 

Jumbo Offshore has completed the removal of two monopiles on the Offshore Wind Farm (OWF) Yunlin in Taiwan. The Jumbo Offshore crew reliably carried out the work, whilst deploying its DP2 Heavy Lift Crane Vessel Fairplayer from Europe to support the onsite operations.  Removal of monopiles Jumbo Offshore was awarded the contract by Yunneng Wind Power Co., Ltd. (YWPC) earlier in 2024 for the removal of monopiles at the Yunlin OWF. The contract award represented an expansion of Jumbo Offshore’s existing scope, involving the transportation and installation (T&I) of the transition pieces.  Under the additional project scope, two monopiles, which previously suffered from a pile run during an earlier project phase, were to be removed. This involved underwater cutting of the monopiles into sections as well as recovery, transport, and offloading of the sections.  Underwater abrasive cutting and lifting tool The individual sections were lifted into the vessel’s cargo hold for transportation to a local Taiwanese port The all-encompassing nature of the scope meant working with Jumbo’s dependable subcontractors. The Fairplayer was outfitted with an underwater abrasive cutting and lifting tool supplied by Claxton Engineering Services, as well as an ROV supplied by IKM subsea and survey equipment by Reach subsea. With these, the Fairplayer could remove the monopiles successfully. The individual sections were lifted into the vessel’s cargo hold for transportation to a local Taiwanese port and offloading to the quayside.  Successful accomplishment For the execution of the works, Jumbo Offshore provided a project management team and the engineering construction crew. From the contract signature to the successful completion of the works, it took just five months including the sailing of the vessel from Europe to Taiwan.  Milad Sheikhi, Head of Sales and Business Acquisition at Jumbo Offshore, stated, "Our dedicated team worked solidly to support our client throughout the project and remained flexible. Achieving what you set out to accomplish successfully and on time is rewarding for the team." Safe and reliable service Milad Sheikhi adds, "Delivering a safe and reliable service as promised is, and always will be our core commitment as a T&I contractor for the Installation and Decommissioning of future offshore wind projects." Jochem Tacx, Package Manager at YWPC, said, "It was a pleasure to collaborate with Jumbo Offshore on this project." Hands-on project management approach Jochem Tacx adds, "The close interaction of the project teams facilitated an efficient execution, within tight schedules and budget constraints. The hands-on project management approach in combination with the in-house technical expertise, resulted in a well-coordinated monopile removal campaign." He continues, "We look forward to continuing the close collaborations with Jumbo Offshore until also the other works scopes on the Yunlin OWF project have been completed."
