Tidewater Transport Christens Towboats

By Mark Edward Nero

The newest inland river towboats in Tidewater Transportation and Terminals’ fleet, Granite Point and Ryan Point, were christened during a June 11 ceremony at Vancouver Landing in Vancouver, Washington.

Tidewater retained the services of CT Marine, Naval Architects and Marine Engineers of Edgecomb, Maine three years ago, to design a towboat that could maneuver barges through the swift-moving currents, high winds and eight navigation locks along the Columbia Snake River System.

Once the plans were developed, Tidewater contracted with Vigor’s Portland shipyard to construct the series of vessels.

“This celebration is the culmination of three years of research, design and hard work,” Schwartz said. “We began the Point Class project with a visionary belief that we could create a vessel that efficiently serves our customers along the river, is environmentally-friendly, and is outfitted with crew endurance in mind. I believe we accomplished our goal.”

The first vessel in the series of three, Crown Point, was christened in June, 2015 and has been in operation for more than a year. The Granite Point recently began journeying upriver, and the Ryan Point is expected follow in early July.

All three vessels are built to the same specifications - 104 feet in length by 38 feet, with a depth at full load of 11 feet, and a hexagonal wheelhouse with floor-to-ceiling windows on all six sides.

The steering system utilizes four main steering and four flanking rudders, coupled with two Caterpillar 3516C Tier 3 engines.

Tidewater also employed Noise Control Engineers of Billerica, Mass. to develop a sound and vibration control package for the vessel. By incorporating Christie & Grey vibration control mounts and comprehensive acoustic insulation, noise levels register at less than 60 decibels during vessel operation – equivalent to an air conditioner.

“The crews that operate these boats say that there is no tug that they have ever operated that gives the operability that these boats have,” Tidewater CEO Bob Curcio said during the christening ceremony. “It’s one hell of a proud day for all the Tidewater folks.”

“These boats will be on the river after all of us are likely gone from this earth,” Vigor Executive Vice President of Fabrication Corey Yraguen said. “That is an astounding thought – that they will be creating jobs and will be a part of the economic engine of our community for a very long time.”

Tidewater Takes Delivery of Vigor-Built Tug

By Mark Edward Nero

Vancouver, Washington-based Tidewater Transportation & Terminals took delivery of the second of a series of three towboats, the Granite Point, on Dec. 22.

The vessel, built by Vigor Industrial’s Portland, Oregon shipyard, follows towboat Crown Point, which began operations along the Columbia Snake River this past May. Like the Crown Point, the Granite Point is a custom-built vessel specifically designed by Maine-based naval architects and marine engineers CT Marine.

Measuring 102 feet by 38 feet, with a depth at full load of 11 feet, the Granite Point has a hexagonal wheelhouse with floor-to-ceiling windows on all six sides.

“We are proud to have worked with Tidewater on Granite Point,” Vigor Executive VP of Fabrication Corey Yraguen said. “Like its sister ship Crown Point, this vessel sets new standards for future towboat design.”

The Granite Point, named for a granite cliff in Washington about 20 miles southwest of Pullman along the Snake River, was built to the same specifications as the Crown Point and forthcoming sister vessel, the Ryan Point.

The Granite Point is powered by two Caterpillar 3516C EPA Tier 3 certified diesel engines each producing 2,240 BHP at 1,600 RPM. The engines drive two 92-inch” by 100-inch fixed pitch, stainless steel propellers through CT28 Kort Nozzles. The vessel’s capable of a service speed of eight knots.

Electrical power is provided by two C7.1, Tier 3 generators, rated at 480 V, 200 kW at 1,800 RPM. The generators are controlled through an automatic transfer system that ensures the vessel can recover from a generator power loss in less than 30 seconds.

Deck machinery includes seven Patterson WWP 65E-7.5, 65-ton electric deck winches, with pilothouse remote operation and local push button control stations on the main deck. Each winch has Samson 1 3/8” Turbo 75 Synthetic Line.

“The up-front work paid off,” Tidewater CEO Bob Curcio said. “The vessels are fuel-efficient, ecologically-responsible, and are giving our captains and crews exactly what they’d asked for.”
