SCHIFFSTECHNIK | SHIP

SCHIFFSTECHNIK | SHIP TECHNOLOGY HyProp Eco for Essberger German operator John T. Essberger ordered new parcel tankers for the joint venture with Stolt Nielsen. They will be outfitted with special components by MAN Energy Solutions Anlagen von GEA sorgen für Frische auf hoher See Mit natürlichem Kältemittel für einen grünen Planeten GEA spielt seit Jahrzehnten eine wichtige Rolle bei der maritimen technologischen Entwicklung. Unsere Spezia listen haben ein umfangreiches Angebot an Kühl sys temen für zahlreiche Schiffe entwickelt. Dabei vertrauen wir auf Ammoniak als Kältemittel, aus gutem Grund: • Natürliches Kältemittel: Mit einem ODP und GWP von null ist es besonders klimafreundlich • Bis zu 20% Effizienzsteigerung: Höhere Effizienz im Vergleich zur Anwendung mit lediglich synthetischen Kältemitteln • Langfristige Investition: Preis und Verfügbarkeit sowie (inter)nationale Verordnungen sprechen für Ammoniak als natürliches Kältemittel Besuchen Sie unsere Website für weitere Informationen www.gea.com/de/marine/ oder melden Sie sich telefonisch unter +49 30 435 92 600 Chinese state-owned China Merchants Jinling Shipyard (CMJL) subsidiary, Dingheng shipyard, has ordered an integrated HyProp ECO propulsion solution from MAN Energy Solutions in connection with the building of four dual-fuel 6,600-dwt, stainlesssteel, parcel chemical-tankers for Hamburg-based tanker operator John T. Essberger. The order includes options for an additional four vessels while the confirmed units are scheduled for delivery from mid-2023. MAN’s scope of supply for each shipset certified by Finnish/Swedish 1A ice class comprises: • 1 × MAN 6L35/44DF diesel/gas-electric propulsion system, including GVU and plant equipment • 1 × Renk gearbox RSVL-1100 including one primary-PTO/PTH/PTI • 1 × MAN Alpha CP propulsion system including AT 3000 propulsion controls • 1 × MAN HyProp ECO – AKA integrated electric system consisting of shaft machine, frequency converter, bow-thruster motor and related AC switchboard enabling tailored modes of operation. MAN will provide the solution in association with Aspin Kemp & Associates (AKA), in which it has a 40 % stake. AKA specialises in power supply, energy management and drive systems for marine applications. Dejan Golub, New Building Manager, John T. Essberger, said: »This propulsion system allows for a straightforward system integration that will make these newbuildings among the most efficient and low-emission in their class.« Lex Nijsen, Vice President and Head of Marine Europe, MAN Energy Solutions, said: »We worked hard to build the case that a fully-integrated solution built around the MAN HyPropECO system would better fulfill the owner’s requirements in terms of increasing energy efficiency and are very glad to have won this order. The scope of supply also matches our desire to increasingly become a supplier of complete solutions.« Jason Aspin, CEO Aspin Kemp & Associates, added »We are very excited that the client has chosen this integrated solution developed though an early supplier involvement and a collaborative design effort, leading to higher efficiency and lower emissions, which are cornerstones of AKA’s design philosophy.« The order pursues a fleet renewal with newbuilds that can increase energy efficiency by 30 %, it was announced. The new ships will be operated by E&S Tankers, a joint venture between Essberger and Stolt Nielsen. In 2020, the Hamburgbased shipping company announced plans to invest significantly in a new fleet of modern ships to trade within their core trades: Northwest Europe, Baltic and the Mediterranean. System characteristics The HyProp ECO system is sait to offer a tailor-made solution where the electric equipment focuses on efficiency and flexibilty. Core components, like the converter unit, are designed to be used in multiple ways, such as for operating the PTO when the propeller runs on the combinator curve, but also to drive the bow-thruster or to supply the ship with shore-power. The system also offers an emergency propulsion mode with the same converter used as PTH starter. »This intelligent layout enables all components to be kept as small as possible. Similarly, integrated bypasses avoid losses in the power electronics when not in use«, MAN stated. The new vessels are planned to be optimised in terms of hull design and equipment, resulting in a significantly improved energy efficiency of at least 30% and will have the ability to use a shorepower connection during cargo operations. The newbuilding project is being subsidised by the German Federal Ministry of Transport and Digital Infrastructure as part of the implementation of the German government’s Mobility and Fuel Strategy (MKS).

SCHIFFSTECHNIK | SHIP TECHNOLOGY THE SCRUBBER MAKER PureteQ scrubber systems feature the lowest OPEX in the business and are easy to install. All scrubber systems come with state-of-theart intuitive control systems with full remote accessibility. It is very convenient and cost efficient to get 24/7 remote on-line support/guidance to ship crews from certified Marine Engineers. We are presently releasing a newly developed cloud-based software for optimizing of scrubber systems across fleet and scrubber makes. It features the measuring of MARPOL compliance, operational performance (impact on SFOC) as well as environmental performance reporting, such as CO2, Sulfur and PM reductions. The software will enable sharing of learnings between crews, resulting in lower energy consumption and other OPEX. The software is a perfect match to new IMO regulation on EED(X)I & CCI when elltoake principle applies. Today, we service all brands of Scrubbers worldwide.
