First fully electric U.S. tugboat is set to operate at the Port of San Diego in 2023

Crowley developing first fully electric tugboat in US
Port of San Diego to gain electric tugboat in 2023.

The first fully electric U.S. tugboat is set to operate at the Port of San Diego’s Tenth Avenue Marine Terminal by mid-2023, the manufacturer announced Monday.

Crowley Maritime Corp.’s 82-foot eWolf vessel will have 70 tons of bollard pull and release zero tailpipe emissions.
It will have 360 degrees of visibility from the pilot’s station and is being designed for potential autonomous operations in the future.
This eTug will replace a conventional tugboat that consumes more than 30,000 gallons of diesel annually, Crowley said.

“The tug was originally designed to complete two standard ship assist jobs in a row without charging or utilizing the backup generator. The eTug is designed to serve harbor and ship assist comparably to current conventional tugs — without any emissions,”

A shoreside energy storage system developed with Cochran Marine will charge the eWolf’s battery system.
The system will have 3 megawatts of battery capacity, which will enable fast charging between jobs,
Solar panels will also be incorporated to charge the eTug with renewable energy.

San Diego is getting nation’s first all-electric tugboat

AUG 9, 2023

The nation’s first all-electric tugboat will soon move ships around the Port of San Diego and on Wednesday officials broke ground on a shoreside charging station that will keep the tug chugging around the Tenth Avenue Marine Terminal.

Operated by Crowley Maritime Corporation, the 82-foot tugboat called the eWolf will slash greenhouse gas emissions for the port and its neighbors in Barrio Logan and National City by running on electricity instead of diesel fuel.

“This is the way the zero-emissions parade is heading,” said Rafael Castellanos, chairman of the port’s board of commissioners. “This is where the world is going and we want to be a pioneer in this technology.”
Capable of speeds of up to 12 knots, the eWolf will be powered by a 6.2 megawatt-hour main propulsion battery and two electric motors. The tug has bollard pull (that is, thrust) of about 70 short-tons, which is comparable to its diesel counterpart at the Port of San Diego, and two small generators for emergency use. The generators also allow the eWolf to travel longer distances at a reduced speed.

The tug boat’s electricity will come from a charging station that, when completed by the end of this year, is part of a microgrid facility equipped with two energy storage containers. Battery modules in each container have storage capacity of nearly 1.5 megawatt-hours.
The charging station is designed to allow vessels to recharge quickly and reduce peak loads on the energy grid. It will be built by a subcontractor hired by Crowley, with San Diego Gas & Electric helping with interconnections.

Currently under construction in Alabama, the all-electric tugboat is expected to arrive at the Port of San Diego in the first quarter of next year. Jackson said the eWolf will replace one of two diesel-powered tugs Crowley operates at the port. That will eliminate the consumption of more than 30,000 gallons of diesel fuel per year.

Since we are on the subject of Crowley Tugs, Does anyone know of any radio freqs they use for ship movement?

If close by to find out what they are using close call or spectrum sweeper should work.
