SV Steelhead II, marks a significant advancement for the MDNR

The new research vessel, SV Steelhead II, marks a significant advancement for the Michigan Department of Natural Resources (DNR) in its efforts to monitor and manage Lake Michigan’s fisheries. The vessel, set to be operational by the 2026 field season, will replace the aging SV Steelhead, which has been a critical tool in fisheries research for nearly 60 years.

The SV Steelhead II will be constructed by Moran Iron Works of Onaway, Michigan, a company known for its expertise in fabricating high-quality vessels. The new vessel will feature state-of-the-art technology, including advanced hydroacoustic systems for more precise data collection on prey fish abundance, which is vital for managing the lake’s trout and salmon populations.

Safety and operational efficiency are key focuses of the new design. The SV Steelhead II will include modern navigational systems, a watertight compartmental hull, and a gyro stabilizer to minimize roll in rough seas, enhancing crew safety. Additionally, the vessel will be equipped with a mechanical platform that can be lowered to water level, facilitating various activities such as diving, equipment maintenance, and crew-overboard recovery.

In an effort to reduce its environmental impact, the SV Steelhead II will be powered by two EPA Tier III diesel engines with high-efficiency emission control technology and will incorporate rooftop solar panels to reduce its carbon footprint. This represents a significant improvement over the original diesel engines of the SV Steelhead.

The vessel’s design and construction reflect the DNR’s commitment to advancing fisheries research and ensuring the safety and efficiency of its operations on Lake Michigan. With the SV Steelhead II, the DNR will continue its critical work with enhanced capabilities and greater reliability for decades to come. Read more here
