A newly built 45-foot twin-screw tug Daniel Joncaire II has been launched for the New York Power Authority (NYPA), the vessel’s designer Bristol Harbor Group, Inc. (BHGI) announced today.
BHGI was awarded a contract by NYPA to engineer, design and perform construction supervision support services for two new tug vessels following its 2009 involvement in the design/build process for NYPA’s new barge, the Havasu II, which led to a study that compared and contrasted the initial and long-term costs to repair and update their existing tugs, or replace them. The analysis led to NYPA deciding to replace tugs Daniel Joncaire and the B-1 Breaker.
The new workboat Daniel Joncaire II was construted at Great Lakes Shipyard in Cleveland, Ohio
. The vessel was designed and built to comply with proposed Subchapter M of Title 46 of the Code of Federal Regulations for inspected towing vessels.
The new tugs will primarily be used for deployment, 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. The vessels will be specially reinforced for operations in seasonal ice and will employ heavy stems for light ice breaking and shell reinforcement along the ice belt. The Daniel Joncaire II also features an elevated pilothouse for improved visibility when maneuvering as well as a spacious work deck aft to facilitate boom connections.
Daniel Joncaire II’s sister vessel is to be fabricated and delivered in 2017 in order to give NYPA an opportunity to operate the first vessel and incorporate any changes they feel would improve the tug or its capabilities. BHGI said it will continue to provide construction supervision services for the second tug.
