Wärtsilä Inert Gas Systems  (2)

Goltens completed a retrofit of a mechanical Woodward 3161 Governor with the latest state-of-the-art electro-mechanical Woodward UG25+ P3 Governor on 2 Wärtsilä 9L20 engines. The new Governor has the same fit and provides the same functionality but with additional features to improve performance. The vessel is equipped with two variable speed Wartsila 9L20 propulsion engines each driving a propeller and fire pump. Each engine is equipped with a mechanical 3161 governor with pneumatic speed setting, shutdown solenoid and start fuel limiter solenoid. Redundant power supplies The engine speed is controlled via a combinator with different operating modes for propulsion and fire pump. The combinator electrical output delivers a mA speed reference to a current to pneumatic converter connected to the 3161 governor. The 3161 governors with pneumatic speed settings are old, unreliable and reaching the end of life thus driving higher repair and spares costs. Fuel system response to engine speed or load changes is suboptimal as well as creating black smoke during the transients. In addition to the 3161, the current to pneumatic converter is also eliminated by using the UG25+P3 electronic governor. The combinator mA speed setting output and shutdown signal input are now directly connected to the UG25+P3 along with redundant power supplies. New junction boxes Port side engine was the first to be retrofitted and the system was tested in all operating modes The start fuel limiter is now managed within the governor software. Goltens Dubai team completed the retrofit, removing the old governor, installing the UG25+P3 with new linkage to the fuel rack, including cable laying and mounting new junction boxes. Port side engine was the first to be retrofitted and the system was tested in all operating modes during sea trials. The UG25+P3 was tuned using the service tool, in which settings for start ramps, fuel limiters, jump rates and PID were optimised to improve performance. The starboard side engine was then converted and the same parameters from the Port side engine were simply downloaded to its UG25+P3. Speed setting changes The overall performance of the vessel was noticeably improved in all areas as mentioned above. The smoke during startup and transients was significantly reduced with very smooth and stable speed control, responding quickly to any load or speed setting changes. The owner now enjoys reduced maintenance cost, better reliability and the knowledge of positively contributing to the environment. The UG25+P3 will be supported by Woodward for many years to come and is already the less expensive option. It is recommended therefore to consider this retrofit as part of the fleet maintenance schedules.

Bud Darr, Executive Vice President Maritime Policy and Government Affairs, MSC Group will be taking part in a Sea Asia virtual panel session, held as part of The Maritime Online Series, which is being organised by Informa Markets.   The Maritime Online Series is a month-long series of online events and specially produced content, running from 21 June to 22 July 2021. With a different theme each week, the series will cover a number of essential topics: Crewing, Regulation, Digitalisation, Environment and Insurance. Ship energy efficiency Bud will join a panel on 14 July at 10:00 CET, titled ‘Progressing Decarbonisation – An Incremental Approach’. The session will be moderated by Edmund Hughes Ph.D., Director, Green Marine Associates, and the participants will discuss the market for transition fuels, tactics for ship energy efficiency and mid to long-term technology advances needed to make progress in decarbonisation. Fellow panellists include Berit Hinnemann (Director, Head of Decarbonisation Business Development, A. P. Moller Maersk), Dominik Schneiter (Vice President, Research and Development, WinGD), and Sanjay Verma (Director – Decarbonisation Solutions, Wartsila Singapore Pte Ltd).

Ocean Now will also build excitement for Nor-Shipping 2022 – the first ‘winter’ Nor-Shipping, taking place 10-13 January in Oslo and Lillestrøm, Norway. “Originally, 1 June was set as the date of Nor-Shipping 2021, but, of course, the pandemic put paid to those plans,” comments Per Martin Tanggaard, Nor-Shipping Director. “So, we wanted to create something to help fill the gap left by the lack of physical gatherings, providing an event where the industry can tap into the latest developments, access opportunity, and continue collaborating. Ocean Now is the result.” Specially curated content “In an age of social distancing there’s more of a need than ever to work together,” adds Tanggaard’s co-Director Karen Algaard. “From our constant contact with the industry we know there are issues that simply won’t wait until we meet again, so we’re delivering a platform where they can be addressed in a meaningful way, today. I’m genuinely excited to see what our partners, participants and audience can achieve through this new kind of dynamic interaction.” From our constant contact with the industry we know there are issues that simply won’t wait until we meet again" Commencing on 1 June, the program is anchored by two headline activities – The Today Show by Nor-Shipping, a unique industry ‘TV style’ talk show on day one, and Nor-Shipping Hydrogen Blue Talks – Fuelling the Future, a new, global conference taking place on 2 June. In between, a range of specially curated content showcases breakthrough projects, innovations and partnerships, while there’s also coverage of a high level UNGC debate in Oslo on shipping’s green transition and much more. Delivering digital content Partner events will see DNV, DNB, Skuld, KONGSBERG and Jotun, among others, deliver digital content focusing on taking positive business #ACTION (the theme of Nor-Shipping 2022) within the ocean space. “From the outset we realized it was pointless to try and offer a digital version of Nor-Shipping itself,” explains Tanggaard. “What makes it so special is that, for one week only, key decision makers from around the world gather, connect and build opportunity together, face-to-face. The whole spectrum of shipping and the ocean industries are represented, making it a true hub for the community, and an unmissable date in the diary. That experience can’t be recreated on a screen. So, we decided we’d do something completely different.” Key stepping stone The Today Show by Nor-Shipping features a range of high-profile guests as well as live music He continues: “We also recognize that, with the proliferation of ‘home office’ throughout the industry, there’s a degree of screen fatigue. That’s why we’ve focused on tailoring something that really is unique, as illustrated by the inclusion of the ocean space’s first, dedicated business talk show. Ocean Now aims to offer something for everyone, and we see it as a key stepping stone on the path to our long-awaited reunion at Nor-Shipping 2022. That will, without a doubt, act both as a celebration and a launchpad for a new era of industry activity.” The Today Show by Nor-Shipping features a range of high-profile guests (including DNB CEO Kjerstin Braathen, DNV CEO Remi Eriksen and Jarand Rystad, CEO Rystad Energy) as well as live music from a special Nor-Shipping band, featuring Ståle Hansen, the CEO of Skuld and Viggo Bondi, Executive Director at the Norwegian Shipowners’ Association and former member of Bridges (pre a-ha), amongst others. Global renewable energy Nor-Shipping Hydrogen Blue Talks – Fuelling the Future, is a day-long paid for event taking place both online and at Nor-Shipping’s Nova Studios in Lillestrøm, Norway.
