The following is the text of a news release from Harley Marine Services:

(SEATTLE) — Harley Marine Services has accepted delivery of its newest tractor tug, Earl W. Redd. The tug is equipped with Caterpillar’s Tier 4 emissions technology and enters the fleet as one of the most efficient and environmentally conscious vessels in the world. Earl W. Redd will not only meet but exceed the toughest marine EPA standards.

Built at Diversified Marine of Portland, Ore., and designed by Jensen Maritime of Seattle, Earl W. Redd measures 120 feet by 35 feet, with a loaded draft of 19 feet 3 inches. The tug features twin Cat 3516 Tier 4 Final main engines that will each produce 2,675 horsepower at 1,600 rpm. Each of the engines is paired with a selective catalytic reduction (SCR) aftertreatment system. SCR uses a urea-based solution to reduce NOx contained in diesel exhaust down to nitrogen and water vapor. The main engines are paired with Rolls-Royce US 255-P30-FP azimuth thrusters delivering a bollard pull capability of 75 tons.

Earl W. Redd has a fuel capacity of 127,000 gallons and can carry 6,534 gallons of water, 1,137 gallons of lube oil, 1,263 gallons of hydraulic oil and 8,200 gallons of diesel exhaust urea. The vessel also features tow and bow winches by Markey and fendering by Schuyler. The bow winch is specially designed for ship handling and escort services. Auxiliary power comes from John Deere 125-kW generators.

Earl Redd, father of Diversified Marine’s owner Kurt Redd, was well-known and loved by everyone he encountered. Redd was a charmer to the fullest extent and a salesman who no one could refuse. He was a 32nd Mason and an athlete, playing baseball, football, basketball, skiing and golfing. He even cleared the pool table, given the opportunity, but the water and fishing were his true passion.

Redd worked for Hyster and U.S. Steel, but found his niche when he landed firmly and found his fit at Harder Mechanical Contractors where he retired at 70. After retirement, he became part of the Diversified team and a strong presence for the remaining 25 years of his life.

The tug will enter service along the West Coast, providing customers with a clean alternative for their transportation requirements.
