Ken led the Portland District navigation and hydrographic survey missions for several years, eventually becoming the Chief of Operations. The vessel bearing his name is a tribute to his contributions to the Corps of Engineers and the navigation community. The Redlinger, from Portland, Ore. The Redlinger has a hydrofoil-assisted catamaran design which gives a stable platform to support channel and harbor condition monitoring and precise surveys of dredging areas.
Her design allows enhanced maneuverability; her hulls are coated with a paint to prevent sealife from adhering to them. The Redlinger's diesel engines produce fewer harmful emissions, and her fuel tanks stand alone inside the hulls, helping minimize risk of a fuel spill. Survey vessel Redlinger is named for Jake Redlinger, a Corps leader who was well respected for his expertise and ability to get things done.
Jake Redlinger was an active proponent of dredging and dredging issues. In , Jake went to Alaska with the dredge Essayons to take part in clean-up efforts following a devastating oil spill in Prince William Sound. Jake was the navigation manager at the Northwestern Division before he passed away on Dec. The West Mark was designed by the U.
Christened in , her name reflects her mission and area of operations. The U. The Essayons, operated by a merchant marine crew, helps maintain the entrance bars, rivers and harbors on the coasts of California, Oregon, Hawaii, Alaska and, in emergencies, the Mississippi River.
Because of its size and dredging depth, the Essayons is particularly well-suited for dredging the larger coastal entrances and larger volume sand deposits in river channels.

Because of its size, the Yaquina is particularly well-suited for dredging the small, shallow coastal entrances and smaller, shifting sand deposits in river channels.

Congress, recognizing the importance of the Columbia and Willamette rivers to the economy of the Northwest, established the Portland District in One of the original goals of the District was to remove obstacles to navigation in the two rivers.

After her sea trials, she was commissioned on January 16, She was transferred to the Philadelphia District on June 24, Essayons was Her hull was constructed of welded steel plates.
Her maximum draft was 28 feet 8. She displaced 9, long tons when light, and 21, long tons with a full load of dredging spoil. Her hull contained twelve hoppers which could hold, in total, up to 8, cubic yards of dredging spoil. These hoppers ran for feet 55 m of the ship's length. Essaysons was propelled by two four-bladed propellers which were 16 feet 4.
She was capable of speeds up to The ship's two oil-fired boilers developed high-pressure steam psig for propulsion and electrical generation. She was crewed by 18 officers and men. Dredging continued around the clock, so the crew worked in shifts. The ship had a machine shop, store, a crew lounge with a ping-pong table, a six-bed medical dispensary, laundry facilities, a cook staff and full galley for meal service, and separate dining rooms for officers and men.
Essayons was at least the third vessel of that name to serve with the U. Army Corp of Engineers and the second dredge. An earlier Essayons was built in to dredge the mouth of the Mississippi. It is a French word which means "Let us try. Essayons was designed to dredge New York Harbor. She sucked sand, silt, and mud off the bottom of navigable waterways to increase their depth, creating a channel allowing larger ships to pass.
She pulled two suctionheads, referred to as "dragheads", along the seafloor as she moved slowly through the water. The dragheads were connected to pipes which were 36 inches 91 cm in diameter called "drag arms" that descended from both sides of the ship.
Using two winches each, these drag arms could be lowered to reach bottom as deep as 60 feet 18 m. Loose material on the seafloor entered the dragheads and was pulled up through the drag arms by 1, horsepower electric pumps. It was then deposited in a hopper in the middle of the ship. All the hoppers were filled after one to two hours of dredging.
Here she opened doors in the bottom of the hoppers, allowing the dredge spoil to fall to the sea bottom. The uniquely long transit associated with the disposal areas off New York Harbor resulted in a design which gave her twice the hopper capacity and significantly higher speed than other dredges at that time. While Essayons was designed to dredge New York Harbor and spent much of her time doing so, she was capable of dredging any major waterway.
Among the areas where she worked were:. The United States government, which had backed Egypt through the Suez Crisis in , leased Essayons to the Suez Canal Authority to assist in widening the canal and repairing damage from the war. An agreement between the two governments was signed in December Essayons left New York Harbor on March 5, All told, she dredged 10 million cubic yards.
She encountered two major issues while working on this project. Despite her experience in busy New York Harbor, the number of ships moving through the canal and roadsteads proved to be a constant challenge. A special set of signal lights was established to prevent collisions. A second issue was the intensely salty water in Great Bitter Lake. She had difficulty evaporating seawater to provide fresh water for the boilers.
Her crew had to clean the evaporators more frequently than normal to keep the salt at bay. She finished her work in Egypt on September 13, The commercial dredging industry had long resented having to compete with government ships for new contracts.
