Marine Vessel Engine Repower

Program Description

The Marine Vessel Emission Reduction Program benefits vessel passengers as well as the coastal counties of New Jersey.  The program is focused on replacing older, less efficient, high emitting marine diesel engines with new cleaner  emission controlled engines.  Integrating new engines into the marine vessel fleet provides decades of useful life to these vessels while providing immediate emission reduction benefits to local communities and the wider region.   This program has generated interest from various marine vessel operators.  This program focuses on providing the maximum amount of emission controls feasible on each marine vessel.  Marine vessel repowers reduce harmful NOx, PM2.5, HC,CO and GHG emissions while greatly reducing fuel consumption and noise.  The useful life of marine vessel repower projects is at least 10-20 years.

DEP partnered with Seastreak, LLC who is a leader in revitalizing fast passenger ferry services between New Jersey and the New York metropolitan area. The company offers high speed catamaran services to a point in Manhattan from central New Jersey. Seastreak operates a fleet of seven vessels between Atlantic Highlands, Jersey City, and Hoboken.

DEP was awarded $1.382 million from a 2014 USEPA $5 million DERA ports grant. Seastreak contributed a mandatory cost share of $2.09 million.

Project Description:

  • Replace four Tier 1 engines with two Tier 3 engine
  • Replace four gearboxes with two propulsion gearboxes
  • Replace four jetdrive propulsion thrusters with two new thrusters properly sized to the new engines

The work was performed at a shipyard in Louisiana. Since the vessel was out of commission for the repower, SeaStreak took the opportunity to refurbish the inside of the vessel by installing new seating and flooring. SeaStreak provided the funding for the refurbishment and it was not part of the grant. The total overall vessel horsepower was reduced from 7500HP to 6006HP. The decrease in the number of engines and gearboxes provided for added space in the engine compartment down in the hull allowing for much easier maintenance.

The repower also resulted in updated computer systems which allow the vessel to be easier to control and maneuver which provided a smoother ride. The upgraded equipment streamlined the electronics. The new system is easier to manage and maintain.

Results:

Annual emission reductions:

  • 5.78 tons PM2.5
  • 132 tons NOx
  • 821 tons CO2

Weight reduction from the decrease in number of engines, gearboxes, and thrusters allowed for increased ridership. Installation of water jet thrusters allowed the vessel to sit higher in the water and reduce drag, giving the vessel a 30% reduction in fuel costs. The new engines are significantly quieter, resulting in noise abatement for the passengers.

Fun fact: Passengers wanted to know when other vessels will get upgraded as this vessel is so pleasant to ride on.

Statue Cruises, LLC

Diesel Emissions Reduction Act

The DEP’s Diesel Modernization Program (DMP) partnered with Statue Cruises on a project that would drastically reduce their overall diesel vessel emissions. Statue Cruises provides several diesel ferries that operate out of New York and New Jersey making around 30 trips a day to visit the Statue of Liberty and Ellis Island.

DEP awarded $279,025 from 2018/2019 USEPA DERA award and Statue Cruises contributed over $418,539 to upgrade the Statue of Liberty V ferry that is moored at Liberty State Park.

Project Description:

  • Replaced two MY 1977 uncontrolled Caterpillar engines with new Tier 3 Caterpillar engines,
  • Replaced two MY 1986 uncontrolled Isuzu Generators with new Tier 3 John Deere generators,
  • Installed, at their own expense, new state-of-the-art Selective Catalytic Reduction (SCR) NOx controls to lower NOx from the Tier 3 engines and generators by over 97%.
  • The total vessel horsepower (HP) was reduced from 2,446 HP to 1,694 HP, reducing the amount of fuel needed for operation.

Annual emissions reductions:

  • 0.6 tons PM2.5
  • 60 tons NOx
  • 225 tons CO2

Fun Fact: Statue Cruises has been ferrying tourists to the Statue of Liberty and Ellis Island since January 1, 2008!
