Hansa Tech-Hub HANSA TECH-HUB NYK | CLASSNK | IHI Alliance to develop ammonia-fueled tugboat In Japan, a further cooperation has been established for the development of ammonia fueled ships. NYK, ClassNK and IHI are targeting a tug concept. The Japanese players want to put the world’s first ammonia-powered tugboat in service. No carbon dioxide is released during the combustion of ammonia. This could reduce the impact of shipping on global warming. The ultimate goal for the company is a zero emissions operation that could be achieved by using carbon-free hydrogen as the raw material for ammonia technologies. The technological development of the fuselage, the engine and the fuel supply system of the new vessel as well as the development of safe navigation methods will be addressed before the end of the fiscal year, the consortium says. DNV GL Approval for centreline oil-tight longitudinal bulkhead on VLCCs DNV GL has presented Hyundai Heavy Industries (HHI) with a general approval for ship application (GASA) for a new concept of very large crude carriers (VLCCs) with a centreline oil-tight longitudinal bulkhead. The new design will reduce potential damage and operational risk by featuring a simpler structural arrangement, loading patterns and piping arrangements, it is said. The new VLCC design concept was developed by HHI, marking a world first. It introduces a single centreline design with two rows of cargo tanks, resulting in seven pairs of tanks and one additional pair of slop tanks. The main benefit is an improvement in the operator’s convenience in terms of cleaning, inspection and maintenance by simpler structural, loading and piping arrangements, as well as the reduction of piping systems and instruments due to a smaller number of cargo tanks, DNV GL stated. Furthermore, the fuel consumption was improved by developing new design lines for the new VLCC. ABB Wasaline ferry gets Azipod propulsion The new ferry »Aurora Botnia« operated by Wasaline is equipped with the ice class Azipod electric propulsion manufactured by ABB. The new ferry, launched by the Finnish shipyard Rauma Marine Constructions, will be used between Vaasa in Finland and Umeå in Sweden. Entering service in 2021, the vessel will have the capacity to transport 800 passengers and up to 1,500 lane meters of trucks and cars, completing two round trips per day in the high season. Designed to meet Polar Code 6 criteria, the vessel’s pair of 5.8 MW Azipod units, where the electric drive motor is in a submerged pod outside the ship’s hull, can rotate 360 degrees and thereby increase maneuverability. According to ABB the Azipod technology also improves the onboard experience for passengers and crew through its quiet-running and vibration-free operation. 58 HANSA – International Maritime Journal 10 | 2020

Hansa Tech-Hub JOTUN – ROBOTIC CLEANING First order by MSC Jotun has signed the first commercial contract for cleaning hulls of container vessels with its robotic Hull Skating Solutions (HSS). The contract was signed with MSC. According to Jotun, the shipping company will install the HullSkater, the first robotic technology that has been designed for proactive cleaning, and the specially developed SeaQuantum Skate antifouling as parts of the Hull Skating Solutions, on the 14,000 TEU vessel »MSC Eva« later this year. The solution will then proactively work to ensure an »always clean« vessel hull, with no biofouling, optimal efficiency, reduced fuel costs and significantly lower CO2 emissions. Jotun unveiled HSS to the market in March this year. Designed to help shipowners facing the most severe biofouling challenges, it combines the antifouling and robotic proactive cleaner, housed onboard the chosen vessel, with proactive condition monitoring, high-end technical service, and performance and service level guarantees. Jotun operators control the HullSkater via a 4G connection, conducting cleaning and inspections in line with individual vessel schedules developed through a proprietary algorithm and big data. TECHNOLOG German-Chinese LNG project In a Chinese-German joint venture, the Hamburg-based company Technolog wants to promote the use of LNG as fuel in shipping with a flexible and self-sufficient container solution. The partners describe their concept of a »Liquid Fuel Gas Container« (LFGC) as a »milestone« and break through on the way to reduce emissions in shipping. Best Ship Energy Management Group (BSEM) from China and Hamburg-based company Technolog-MRS have now signed an agreement for the design, production and distribution. Classification societies DNV GL, American Bureau of Shipping (ABS) and China Classification Society (CCS) have already issued the »Approval in Principle«. Type Approval for the system is expected by the end of 2021 after the 20’ and 40’ prototypes have been built in Europe. HEADWAY Cooperation for fuel gas supply Headway Technology Group has signed a framework agreement with Rui Neng Ocean Shipping to establish a cooperation on Fuel Gas Supply Systems (FGSS), Ballast Water Management Systems, Communication & Navigation Systems, and Intelligent Ship Management Systems to effectuate mutual development. Headway’s OceanGuard FGSS can provide self pressure built-up, low pressure, high pressure, and BOG fuel gas supply solutions. By the breakthroughs in processing technology, automation of safety barriers, and safety control management, OceanGuard FGSS has significantly increased core technology and components’ independence. • Drahtseile • Tauwerk • Festmacher • CASAR Bordkranseile • Anschlagmittel • Prüflasttest bis 1.000 t • Segelmacherei • Taklerei • Montage Walter Hering KG Porgesring 25 22113 Hamburg Telefon: 040 – 73 61 72 -0 eMail: info@seil-hering.de www.seil-hering.de HANSA – International Maritime Journal 10 | 2020 59
