JONCAIRE II

Tugboats/Towboats

Bristol Harbor Group, Inc. (BHGI) was awarded a contract by New York Power Authority (NYPA) to engineer, design, and perform construction supervision support services for two (2) new tug vessels. The tugs are used primarily for deployment, and the retrieval and maintenance of an ice boom annually installed near the outlet of Lake Erie to help protect NYPA’s hydroelectric plant intakes on the Niagara River from heavy ice flows.

BHGI began with an initial site investigation of the JONCAIRE and B1-BREAKER. The investigation included a detailed review of the existing vessels and their operation, a comparison to the desired specifications as outlined in the RFP, and careful consideration of the deviations proposed for the new vessel. BHGI also engaged with the vessel operators to help determine design features they recommend to be added to the vessel. The construction of the JONCAIRE II has been completed. BHGI developed and revised the second vessel specifications and bid drawing package in close collaboration with the operators, including significant detailed system design for the second vessel to provide improved ergonomics for the crew, and is presently supporting NYPA with bid evaluations and award recommendation. NYPA recently awarded a contract to a shipyard for the construction of the B-2 BREAKER tug. BHGI will again be performing construction oversight services on behalf of NYPA.
