ONE-THIRD OF FLEET TO HAVE EXHAUST GAS SCRUBBERS BY SPRING 2016
The James R. Barker sailed into Fincantieri Bay Shipbuilding Company in Sturgeon Bay,Wis., last week where it will become Interlake Steamship Company’s first thousand footer and its second self-unloading bulk carrier to be outfitted with exhaust gas scrubbers.
Interlake became the first US-flag fleet to test scrubbers on the Great Lakes in April 2015 after pioneering the emission- reduction technology on its Hon. James L. Oberstar.
Fincantieri Bay Shipbuilding handled the successful installation on the 806-foot Oberstar and was the clear front-runner to earn the second phase of installations on two additional vessels —— the 1,004-foot Barker and the 826-foot Lee A.Tregurtha, which just arrived at the Wisconsin shipyard.
“We’re excited to extend this proven, innovative scrubber system to our 1,000-foot class ships and further reduce our fleet’s carbon footprint,” says Interlake President Mark W. Barker. “We have the utmost confidence in the expertise and technical abilities of Fincantieri Bay Shipbuilding to implement the technology and help propel us toward our long-term vision of being an environmental leader on the Great Lakes.”
During the multi-month project at Fincantieri Bay Shipbuilding, both vessels will be equipped with the same single- inlet, closed-loop DuPontTM Marine Scrubbers from Belco Technologies Corp. (BELCO), a DuPont company, that were installed on the Oberstar.
“Fincantieri Bay Shipbuilding is pleased to have been selected to lead these scrubber installation projects,” says Todd Thayse, Vice President & General Manager of Fincantieri Bay Shipbuilding. “Interlake’s commitment to leading environmental technology on the Great Lakes is once again demonstrated and we appreciate Interlake’s confidence in Fincantieri Bay Shipbuilding to once again partner with us for this important project.”
The scrubber units, which are attached to the exhaust system of each of the ship’s two engines, effectively strip the majority of sulphur from its stack emissions. Here’s how the systems work: Exhaust gas from the engine is sent through a series of absorption sprays that ‘wash’ and remove impurities, specifically sulphur and particulate matter. That washed exhaust gas then travels through a droplet separator before a clean plume of white steam is discharged into the atmosphere.
“The sulphur reductions we have been able to achieve in the first year of operation have exceeded our expectations,” says Barker, adding that the additional reductions of these emissions make an even stronger case for marine transportation — the most environmentally friendly way to deliver, in Interlake’s case, raw materials.
