What made this Mitsubishi engine the ideal solution to power a new tug?
Details associated with how Mitsubishi motors can be used simply and powerfully in large-scale boats are readily availablealong with other information that shows how specific products like the Mitsubishi S6R2-Y3MPTAW measure up to the competition. These distinctions are easy enough to see on paper, but do such efficiencies carry over into the real world?
The team at Navy Dungeon put this question to the test as the Mitsubishi S6R2-Y3MPTAW engine was their choice to power their new tug. Providing complete solutions for salvage at sea, towing, dredging, heavy hauling, material recycling and related services means decisions like these impact a variety of tasks that Dungeon Tug Captains and Engineers must do daily. The Mitsubishi S6R2-Y3MPTAW turned out to be a “perfect fit” for them for many reasons.
Beyond a need to meet propulsion needs
Founded in 1964 by J. Arnold Witte, Dungeon Marine Co., Inc, has become a leader in the dredging and offshore recovery industry. The addition of Don Jon Shipbuilding and repair in Erie, Pennsylvania, has allowed the company to become a multi-faceted marine service provider. In partnership with Smith As a salvage contractor for the United States Navy, Donjon has positioned itself at the forefront of the global maritime salvage industry by enhancing its fleet through acquisitions, newbuilds and re-engines.
The current and future needs of the fleet and the organization are at the heart of the concerns of Captain William J. Sullivan, responsible for regulatory compliance and ship repair at Donjon, particularly as it relates to the construction of new ships. . Motors are obviously a primary consideration for these projects, but cchoosing one solution over another to meet their propulsion needs is not limited to a single feature or requirement. Rather, it’s about looking at how these features and needs will be addressed on a much larger scale.
“In today’s regulatory environment, many factors must be considered when choosing propulsion requirements,” Sullivan said. “You often have to work backwards from the desired end result. In other words, if you know the bollard power you want, what combination of vessel size and propulsion can get you there? What are the latest environmental restrictions for engine emissions? Given current fuel prices, are the engines efficient? Does the engine manufacturer have a reputation for reliability? While there are many variables that determine our propulsion solution, some of the most important factors to consider are answered in these questions.
These questions prompted the Dungeon team to specifically explore the higher displacement ratios, low compression ratios and minimal stress of Mitsubishi engines. After that, they determined that Mitsubishi engines were the best solution to power their new tug. Their decision made a real difference to Donjon tug captains and engineers, underscoring the importance of these initial considerations and final decisions. It is a difference that is felt on all sides.
“Mitsubishi is excited about this project and the growing popularity of the S6R2 in twin-screw and triple-screw applications,” said Rodrigo Teixeira, marine manager at Mitsubishi.
Performance, feedback and adjustment
To say that there are a variety of powerful and capable motors on the market is an understatement. Companies that are essentially household names produce engines that power entire fleets, meaning these products can meet the basic needs of a variety of commercial vessels. As always, the devil is in the details, which real Dungeon users can attest to on many levels.
“Our tug captains and engineers have expressed satisfaction with the performance of the Mitsubishi engines compared to other similar powertrains,” Sullivan explained. “Confidence in the reliability of the engine was repeatedly noted as the vessel was considered a workhorse. We knew we needed a motor that could meet our horsepower needs while having a small footprint and manageable weight. That’s what made the S6R2-Y3MPTAW engine the perfect fit for us, and the feedback we’ve received has again confirmed it.
This fit for Donjon is ultimately based on the fact that Mitsubishi mechanical diesel engines offer higher displacement ratios, lower compression ratios and minimal stress on its components. However, the specific fit with the needs of Dungeon Captains and engineers point out what it can mean for an engine to be that kind of “perfect fit”, which commercial engine distribution companies can support more.
“It was a pleasure working with Donjon on this 2400 hp triple screw tug,” said Trace Laborde, Vice President of Sales, Laborde Products. “After our analysis of the application as well as travel, bollard pull and longevity. We came to the conclusion that the Mitsubishi S6R2 was the best engine for this project.
Selecting the best engine is one of the most important decisions a vessel owner can make, which underlines why considerations for everything from horsepower to displacement to weight are so important to make. . The capabilities of the Mitsubishi S6R2-Y3MPTAW made it an easy choice for Dungeon, but will it be just as easy a choice for other commercial ship players?
Ultimately, the appeal of the Mitsubishi S6R2-Y3MPTAW is that it’s a simple yet powerful engine that’s easy to maintain. When stacked against other 800 horsepower engines, the S6R2-Y3MPTAW can work harder with less strain, but can it also meet the myriad propulsive factors that Sullivan mentioned every ship responder must take into consideration? account ? These answers can only be assessed as part of the process that anyone making such decisions must follow, highlighting the need and importance of asking and answering these questions.
