Kirby Offshore Wind

Kirby enters the renewable energy space through a 20 year partnership with Maersk

9
Under the 20-year framework agreement:

‒ Kirby will provide barge transportation services for offshore wind towers and turbines to Maersk Supply Service

‒ First project is Empire Offshore Wind, a joint
venture between Equinor and bp off the
coast of New York

9
Capital investment: $80-100 million for two feeder barge and diesel-electric hybrid tugboat units
9
Each feeder barge will have the capacity to transport next-generation turbines of 15 megawatt and greater
9
Operations are expected to commence in late 2025 or early 2026

In the last 10years Kirby’s investment strategy has…

As engine tier level increases, engines produce less emissions and become more efficient and environmentally friendly

Engine Tier Strategy

9

Since entering the offshore market Kirby’s investment strategy has reduced Tier 0 engines by 95%

9

Since 2015 Kirby’s investment strategy has spent
$200M+ on Tier 3 and 4 engines and boats

Ballast Water Management

9

In the less than a decade, Kirby has installed ballast water treatment systems on 62% of its fleet

9

By the end of 2024, Kirby will have all remaining
vessels outfitted with ballast water treatment systems

Kirby is committed to a cleaner and more efficient offshore fleet

Since 2017, Kirby Inland Marine has spent over $9 million dollars investing in solar panels for over 600 barges that power the high-level alarm systems

  • Allows the barges to load and discharge at facilities that do not have high level alarm hook ups on shore
  • Ensures tankerman can use the alarm system on loads and discharges which gives them a safety system to help prevent spills to the environment
