New tug boosts Pacific interisland towage
Young Brothers christened Kāpena Raymond Alapai in Hawaii as a second of its Kāpena-class tugs

A second low emissions tugboat has been introduced to the Hawaii fleet to improve trade between islands with lower emissions.

Young Brothers has christened Kāpena Raymond Alapai in Hilo, Hawaii, as a second of its Kāpena-class tugs that comply with the US Environmental Protection Agency’s Tier 4 emissions requirements.

This follows the introduction of sister tug, Kāpena Jack Young, in July 2018. Two more tugs of this class are on order from Louisiana-based Conrad Shipyard. The Kāpena-class of tugs will advance towage in Hawaii with faster speeds and a lower carbon footprint.

The addition of Kāpena Raymond Alapai increases Young Brothers’ fleet to six tugboats and eight barges, all servicing the Hawaiian Islands. It transports almost 100% of all cargo by ocean that originates and ends in Hawaii. Its fleet operates in seven ports on Oʻahu, Kauai, Maui, Lānaʻi, Molokaʻi, and Hawaii islands.

“Our new tugs will reduce carbon emissions, increase fuel savings and help advance Hawaii’s energy sustainability goals,” said Young Brothers president Joe Boivin.

These tugs are built to a Damen USA design with General Electric 8L250 MDC engines with compliant exhaust gas recirculation to EPA Tier 4. They are 37.5-m long, 11-m beam tugs with 4,475 kW of power each.

Two more Kāpena-class tugs are due to join the fleet this year with Young Brothers planning to hold a blessing for all four in Honolulu in June 2019.


Emission reduction strategies will be among topics discussed at the Americas Sulphur Cap 2020 Conference organised by Riviera Maritime Media in Houston on 5-6 March. Book your place now.
