MARCH 19, 2015 —GE Marine announced that Reinauer Transportation Companies, LLC, purchased two GE U.S. EPA Tier 4 certified marine diesel engines and two Lufkin Marine Propulsion Gearboxes for a new Articulated Tug and Barge (ATB) to be built at Senesco Marine, North Kingstown, RI.
Lufkin is a part of GE Oil & Gas. Reinauer acquired Senesco in 2006. The shipyard is scheduled to deliver the ATB in early 2016. Local engine support will be provided by GE Marine's Distributor, Cummins MidSouth.
"We chose the new GE Marine engines because we like the robust design and component configuration of the engine. The engine closely matches the footprint of our current vessel design. This limits the amount of re-engineering while meeting Tier 4 emissions requirements without the complications of urea after-treatment," said Christian Reinauer. "Lufkin gearboxes have proven their reliability and ruggedness with their past performance in three of our Nicole Class ATBs starting in 1998."
"We are delighted that Reinauer chose our new EPA Tier 4 certified diesel engines and look forward to delivering it next year. Our engines require no Selective Catalytic Reduction (SCR) after-treatment or urea injection, which saves customers significant space, weight and infrastructure costs," said Afra Gerstenfeld, General Manager of GE Marine.
"We also take great pride in Reinauer's continued confidence in our American Bureau of Shipping (ABS) rated gearboxes for dependability in heavy-duty workboat applications such as ATBs," said Darin Swartz, Product Management Director for Lufkin.
A study conducted by Jensen Maritime was commissioned by GE to compare its U.S. EPA Tier 4 and IMO Tier III compliant in-engine, urea-free solution to other solutions on the market that use urea based after treatment. It concluded that, for operation on a typical line-haul tug, GE's solution:
- Reduces approximately 75% of the engine room space required by the other market solutions;
- Reduces weight by approximately 75% versus the other market solutions; and
- Does not require additional onboard equipment/storage for urea or dockside support infrastructure for urea storage and processing.
GE Marine was recently granted U.S. EPA Tier 4 certification for its 12-cylinder V250 marine diesel engine. GE Marine is working to achieve U.S. EPA Tier 4 and IMO Tier III certification for its entire family of V250 and L250 marine diesel engine models that also utilize non-SCR technology to reduce key emissions by an estimated 70%, without the use of urea based after-treatment. .
