Project Description: Repower of R/V Harold Heath

Summary

In October of 2015 the Carl Moyer federal program for marine vessel repower awarded a grant to the Seafloor Mapping Lab at California State University Monterey to pay for the replacement of the aging diesel engines aboard the R/V Harold Heath, a 46’ Hatteras and largest of CSUMB’s research vessel fleet. New twin Volvo marine diesel engines have now been installed as well as a new diesel generator. These changes have increased fuel efficiency by 30% and have eliminated the sooty exhaust that plagued the original Cummins diesels. This change has also significantly reduced the overall weight of the vessel allowing greater passenger and instrumentation payloads, and increased the cruising speed to over 20kt.

Student Involvement

An enthusiastic group of 6 undergraduate student volunteer interns have been critical to the success of the repower project. These students participated in the haul out, cleaning and stripping of the hull, flying bridge, cabin and decks in preparation for the install, as well as re-installation and/or new fabrication of all components removed. The interns will now become deck hands for weekly maintenance runs in the Bay required to keep the vessel in top trim, and on research cruises.

Broader Significance

The Carl Moyer Program’s purpose is to reduce regional contributions to air pollution by outdated diesel engines that federal policy requires be taken out of service. CSUMB’s main research vessel, which qualified for this grant program due to the large number of sea days and heavy fuel consumption over the past several years, is now a highly efficient and clean running research and education vessel, consistent with CSUMB’s emphasis on environmental sustainability.
