This Shark Class Dredge features an 18-in. hull-mounted dredge pump and 300 hp cutter drive assembly, and has a dredging depth capability of 56 ft. DSC supplied stainless steel hydraulic fit- tings and used anti-corrosion building practices, as the dredge will be work- ing in a corrosive environment. The minerals company also purchased an anchor barge fabricated by DSC, which included a Tier 4 Final engine for the hydraulic winch drive system. The U.S. Environmental Protection Agency (EPA) Tier 4 Final emissions standards went into effect for dredges in 2016. Engines ranging from 2,682 to 4,962 hp (2,000-3,700 kW) were first affected by the standards. But since October 2017, all new engines with a maximum power of 804 hp (600 kW) and greater must meet U.S. EPA Tier 4 Final emission standards. DSC worked closely with Caterpillar for this "green" build. According to David Ezell, OEM account manager for Michigan CAT, "DSC and Michigan CAT utilized a strong engineering collabo- ration to install the first Tier 4 Final engine in a DSC Shark dredge – the C32 Tier 4 Final 1,125 hp. The C32 Tier 4 Final engine is a 32-liter 12-cylinder V-engine with horsepower ranges from 1,000 hp to 1,125 hp. The C32 has industry-leading torque of 4,056 ft.-lb. at 1200 rpm. Ezell explained that Caterpillar was able to achieve the Tier 4 Final regulations in the C32 with the use of the Caterpillar NOx Reduction System and dual main- tenance-free diesel oxidation catalysts (DOC). "The robust Caterpillar Tier 4 Final engines were tested and proved with more than 4.6 million hours of in-field testing and validation to deliver highest horsepower and torque ratings with lowest cost of ownership in the industry," he added.
