Slowing ships means cleaner air, safer whales, and a quieter ocean.

Vessel Speed Reduction program continues to expand and achieve greater environmental benefits

CALIFORNIA, USA, April 21, 2023/EINPresswire.com/ — Twenty three shipping companies participated in Protecting Blue Whales & Blue Skies vessel speed reduction program in 2022, contributing to cleaner air, safer whales, and a quieter ocean. Companies are recognized for their vessels transiting at ten knots or less in the San Francisco Bay Area and the Southern California region.

The voluntary incentive program ran May 1- Dec 15, 2022. Participation was greater than any previous year, increased from eighteen shipping companies participating in 2021. Shipping companies received recognition and financial awards based on the percent of distance traveled by their vessels through the Vessel Speed Reduction (VSR) zones at 10 knots or less and with an average speed of 12 knots or less.

The three award tiers are Sapphire (85-100% of fleet total distance in VSR zones traveled at ten knots or less), Gold (60-84%), and Blue Sky (35-59%). Automatic Identification System (AIS) transponders on each ship transmit the ship’s speed and location. AIS data was analyzed for each fleet and the company’s performance was classified by tier.

Eight participating companies reached the Sapphire level, the most in the top category since the program began. They include Orient Overseas Container Line (OOCL), Mediterranean Shipping Company (MSC), Swire Shipping, Yang Ming, COSCO Shipping, NYK Ro-Ro, Wallenius Wilhelmsen, and CSL Group.

For the fifth year in a row, MSC notably achieved the Sapphire tier in the large fleet category and demonstrated that advance planning enables ships to adjust their schedule to cooperate with the VSR program without disrupting operations. Orient Overseas Shipping Line, a new participant in the program, notably achieved a 95% cooperation level in 2022, reducing speeds to 10 knots or less for over 15,000 miles in the California zones.

The ten-knot target complements NOAA, U.S. Coast Guard, and Environmental Protection Agency requests for all vessels (300 gross tons or larger) to reduce speeds during the months of peak air pollution and endangered blue, humpback, and fin whale abundance to protect these whales from ship strikes.

Ship strikes are a major threat to whales globally and to the recovery of endangered whales in California waters. Reducing the risk of ship strikes is a major priority of NOAA’s West Coast national marine sanctuaries. Observed and documented deaths totaled 52 endangered whales from 2007-2022, and likely represent only a small fraction of the total number of ship strikes taking place annually.

The timing of the program coincides with the season when ground-level ozone (smog) concentrations are typically high. The 10-knot target allows ships to travel at an efficient operating load using less fuel and producing less pollution. Ocean-going vessels transiting the California coast generate nitrogen oxides (NOx, a precursor to smog), sulfur oxides (SOx), particle pollution, and greenhouse gasses (GHGs). These vessels account for nearly 200 tons of NOx per day emitted off the coast of California, which affects ozone levels onshore in many regions of the state. The areas of greater Los Angeles (including Ventura County), Santa Barbara County, and the San Francisco Bay do not meet the state and/or federal air quality standards for ozone.

The VSR incentive program has expanded in scope and environmental benefits each year, including 2022, which marked the seventh year. Of the 344,000 nautical miles of ocean transited by all the ships in the program, nearly 270,000 nautical miles were at 10 knots or less, which is equivalent to traversing the circumference of the Earth more than ten times.

Ships in the program transiting the southern California VSR zone traveled at 10 knots or less for 79% of the total miles traveled. Cooperation has steadily increased season after season. This shows the increasing commitment by the participating companies over the years. In the SF Bay Area VSR zone, expanded in 2022, cooperation levels by the participating companies rose to 72%, up from 60% in 2021.

Shipping companies in the 2022 program reduced air pollutant emissions by approximately 920 tons of NOx and 32,000 metric tons of regional GHGs. This represents a 27% reduction in NOx and GHG pollution from the ships that participated in the program, as compared to baseline conditions–equivalent to converting 580,000 passenger vehicles to zero emissions for a single year.

Transits of participating vessels posed approximately 44% less strike mortality risk to whales than if those vessels did not slow. Ships in the Sapphire, Gold, and Blue Sky award tiers had sound levels that were 4.6 dB per transit lower when compared to 2021 baseline source levels. With a reduction in noise pollution, whales can likely communicate easier.

Incentives ranged from $2,500 to $20,000 per company in the Gold and Sapphire award tiers. Fourteen companies – OOCL, MSC, COSCO Shipping Line, CSL Group, Ocean Network Express (ONE), Maersk, “K” Line, Wallenius Wilhelmsen, Wan Hai, Evergreen Shipping, Swire Shipping, Hapag Lloyd, GALI, and Yang Ming – generously declined all or part of their financial incentive payments to be reinvested in the program.

The 2023 program runs May 1 through December 15, 2023. This will be the biggest season yet for whale protection and clean air, with tanker operators invited to join. Expansion of the San Francisco VSR zone will extend the area by ~130 miles to include all of Monterey Bay National Marine Sanctuary. With expansion, three new partners are joining the 2023 program: Monterey Bay National Marine Sanctuary, the Monterey Bay Air Resources District, and San Luis Obispo County Air Pollution Control District. The 2023 program will not feature financial incentives, due to participants’ feedback in support of the vessel speed reduction effort and public recognition.

Protecting Blue Whales and Blue Skies partners include Ventura County Air Pollution Control District; Santa Barbara County Air Pollution Control District; San Luis Obispo County Air Pollution Control District; Monterey Bay Air Resources District; Bay Area Air Quality Management District; Channel Islands, Greater Farallones, Cordell Bank, and Monterey Bay national marine sanctuaries; The Volgenau Foundation; California Marine Sanctuary Foundation; National Marine Sanctuary Foundation; Greater Farallones Association; Environmental Defense Center; Point Blue Conservation Science; Starcrest Consulting; and Scripps Whale Acoustic Laboratory/Scripps Institution of Oceanography.
