Harvey Energy Tri-Fuel Vessel Shapes Future of Sustainability

The Harvey Energy will become the first ABS-classed dual fuel and battery vessel and the first U.S. flagged OSV equipped with a battery/converter system.




As of January 1, 2023, all ocean-going vessels must report each vessel visit within 30 days of departure and meet opacity requirements.

Emissions controls compliance start dates are based on vessel type. 


Vessel Type Compliance Start Dates
Container and refrigerated cargo vessels
January 1, 2023
Cruise (passenger) vessels January 1, 2023
Roll on/roll off vessels January 1, 2025
Tanker vessels that visits the Ports of Los Angeles or Long Beach January 1, 2025
All remaining tanker vessels January 1, 2027


Once a vessel type has reached it compliance start date then the vessel must:

• Coordinate with regulated terminals at least 7 days prior to arrival and complete all items in the compliance checklist as set forth in section 93130.7(e).

• Reduce emissions while at a regulated terminal in accordance with the regulation’s performance standards by:

o Connecting to shore power

o Employing a CARB approved Emission Control Strategy (CAECS) or an approved innovative concept

These are to be employed within two hours of the vessel arriving at the berth and continue until no sooner than one hour before the pilot boards the vessel for departure from the berth.

Emissions controls will not apply for vessels visiting an unregulated terminal. A terminal that received less than 20 visits in both 2021 and 2022 from a vessel type is initially considered a low activity terminal and is unregulated for that vessel type. A low activity terminal that receives 20 or more visits per year for two consecutive years from a vessel type that is becoming a regulated terminal for that vessel type and shall reduce emissions starting January 1 of the following year.
