Vigor's Harbor Island Shipyard in Seattle is fitting out the fourth and last Olympic-class ferry for Washington State Ferries. It was christened Suquamish in a traditional maritime ceremony on January 4. The 362-foot vessels can carry 144 vehicles on two decks and 1,500 passengers. Propulsion comes from twin EMD 12-710 engines producing 6,000 total horsepower for a service speed of 17 knots. The four-vessel contract is worth more than $500 million.

The new ferry will begin its sea trials in mid-2018 and will start carrying passengers beginning in the fall on the Mukilteo/Clinton route in the summer and as a maintenance relief vessel in the winter. The name honors the Suquamish people, a tribe that has inhabited the central Puget Sound for approximately 10,000 years. It means "people of the clear salt water" in Southern Salish Lushootseed language.

Washington State Ferries, the nation's largest ferry system, also announced that ridership grew by more than 250,000 over 2016, increasing for the ninth consecutive year to nearly 24.5 million passengers. "We expect our ridership to continue to grow as more people move to Western Washington," said WSF head Amy Scarton. "As part of the state highway network, the ferry system is a critical link between more affordable housing on the west side of the Sound and key employment centers on the east side."

Vigor's Shipyard in Ketchikan, Alaska, continued work on two 280-foot ro/pax ferries for the Alaska Marine Highway System. Elliott Bay Design Group designed the vessels named Tazlina and Hubbard, which can hold 300 people and up to 53 vehicles each. The two ferries will be delivered in 2018. All 23 modules are now complete for the first ferry and in place. Interior work continues with piping, painting and insulation in the engine room, electrical crews continue to terminate panels and equipment throughout the ship and continue trimming out lights, switches and receptacles in conjunction with the joinery installers. It is scheduled for delivery in late 2018.

Vigor was recently awarded the contract to build two additional all-aluminum, 400-passenger ferries designed by Incat Crowther of Australia for WETA (the Water Emergency Transportation Authority) in San Francisco, California. The hulls will be constructed at Vigor Ballard (formerly Kvichak) and the superstructure at Vigor's Harbor Island Shipyard. "It's a very efficient design and very environmentally friendly. We're extremely pleased to extend our partnership with WETA for two more vessels," said Tim Kolb, general manager of Vigor Ballard.

The 135-foot by 38-foot catamarans will be driven by two MTU 12V4000 M64 EPA Tier 3 engines rated at 1,875 hp at 1,800 rpm, turning Michigan Wheel nibral propellers through ZF7600 reduction gears. Service speed is 27 knots. Each engine is equipped with a Hug Engineering selective catalytic reduction (SCR) exhaust treatment system, which makes these cats two of the lowest-emission ferries currently operating in North America.

Mavrik Completing Third Catamaran Tourboat

Having delivered two MAN-powered catamaran tourboats more than 90 feet long in 2017, Mavrik is completing a third for Major Marine Tours, which also operates wildlife viewing tours in Prince William Sound's Kenai Fjords National Park from its base in Seward. Major already operates a fleet of seven vessels based in Seward and Whittier – five monohulls from 58 to 100 feet and three catamarans 78 to 87 feet long.

This new 149-passenger Coast Guard-inspected catamaran is also designed in Australia by One2Three naval architects but is powered by a pair of Caterpillar C 32's rated at 1,450 hp at 2,300 rpm. "We are very happy to partner with One2three on these outstanding boats," said Zachery Battle, founder and president of Mavrik.

He pointed out that he was also about to launch a 70-footer from the same designers for the Pacific Whale Watch Foundation of Maui. The Guardian features a height-adjustable swim platform on the stern, stadium seating on the foredeck, and a walk-around pilothouse with additional port and starboard steering stations. Power comes from a pair of 436 HP Tier-3 Cummins QSM 11's for an economic cruising speed of 15 knots, and fast cruise of 18 knots.

Nichols Nat Geo Connection

Among a number of notable contracts, Nichols Brothers Boat Builders of Whidbey Island delivered the first of two 238.5-foot small cruise ships to Lindblad Expedition Holdings last summer. Work is well under way on the second vessel to complete this $94.8 million contract- the National Geographic Venture. This is a sophisticated design by Jensen Maritime Consultants of Seattle with a 48-foot beam and 50 luxurious double-occupancy cabins. It is powered by twin Caterpillar Tier 3 engines with a total of 3,200 hp turning twin propellers that will drive the ship at about 12 knots. With a draft of less than 10 feet they are designed to visit small ports in Baja Mexico, Costa Rica, and Panama during the winter months; and Oregon, Washington, Alaska and Canada during the summer.

In keeping with the hands-on style of these trips, both are equipped with Zodiac inflatables and kayaks, snorkeling gear, exercise equipment, and a wide range of cameras to record the surrounding wildlife.

A photo instructor, a video chronicler, an undersea specialist, and a wellness specialist accompany every voyage; and Internet access and an elevator are available on board. The guests will also find state-of-the-art expedition technology, including a remotely operated vehicle, video microscope, and a hydrophone and bow-cam designed for immediate bow deployment to hear and film marine life.

All American Hybrid Tourboat

All American Marine in Bellingham, Wash. is constructing a 600-passenger, 128-foot hybrid-electric vessel for Red and White Fleet of San Francisco, which is expected to be completed by late spring. Named Enhydra, this will be the first vessel of its type built in Washington and according to the builders, it will be the largest lithium-ion hybrid vessel built in the US. It conforms to the US Coast Guard sub-chapter K passenger vessel regulations and the latest guidelines for structural fire protection. The contract is valued at nearly $7 million.

All American Marine partnered with BAE Systems to design and integrate the complete battery electric hybrid system. BAE Systems will supply their HybriDrive Propulsion System that includes a generator, control system, and AC electric traction motor. The generator will mount to a variable speed Cummins QSL9 410 diesel engine. The motor generator offers diesel-electric operation of the AC traction motor, which is coupled directly to the propulsion shaft. With this configuration, torque is immediately available for the propeller and the speed can be precisely controlled without the need for a reduction gear.

The hybrid system will also utilize battery power from two 80 kWh Lithium-ion battery packs. The batteries will come from Corvus Energy of BC and are supplied under their next generation Orca Energy line. The BAE HybridDrive system can automatically utilize full electric battery operation at slower speeds and when maneuvering in and out of the Harbor. At higher speeds, the generator will automatically engage and augment the additional power demands of the traction motor. The battery system is sufficient to meet the entire demand of the vessel's hotel load while at the same time providing silent and emission-free operation of the propulsion system during an evening sunset cruise.

Jesse Engineering Launches Global Provider

Maxum Petroleum, Inc. expects its 150,000-barrel self-propelled bunkering vessel Global Provider to complete sea trials in February. This 126-foot by 32-foot design from Elliott Bay Design Group (EBDG) was built by Jesse Engineering in Tacoma, Washington with 10 feet of draft, and a 13-foot depth of hull. EBDG balanced the vessel's performance with fabrication cost while remaining under 100 Gross Tons. The vessel displaces 326 long tons lightship and has an ABS loadline.

The six pairs of cargo tanks provide 3,700 bbls of MGO and 24,000 gallons lube oil capacity. The cargo handling system allows the vessel to move segregated products, lube and fuel oil without cross-contamination. Power is provided by a pair of Cummins QSK-19M, 660 HP Tier 3 engines with Twin Disc MGX 5170DC 3.12: 1 reduction gears driving two fixed pitch 99-inch diameter propellers. Reliable steering and exceptional maneuverability when coming alongside ships is ensured by a pair of Deflector high-lift rudders.

Northern Lights Gensets will supply electrical and hydraulic power. A Rapp Marine HP20-2K 30-foot crane is fitted to handle heavy hoses. "The Global Provider is the result of years of collaboration between our Maxum Team, our valued customers, Elliott Bay Design Group (EBDG) and Jesse Engineering to develop a tank-ship with the versatility and capacity to enhance our commitment to quality and customer service to meet the mission critical needs of our valued clients," said Dan Kovacich, VP of Maxum Petroleum.

Diversified Building More Tugs

Diversified Marine in Portland, Ore. delivered the Teresa Brusco, its seventh ASD tug for Brusco Tug & Barge of Longview, Washington, early in 2018. All seven vessels are built to the standard 78-foot Cates design by Robert Allan Ltd. of Vancouver, British Columbia. The new tug is fitted with Caterpillar 3512C Tier 3 main engines rated at 2,366 hp each, turning Rolls-Royce ASD's with 94.5-inch propellers. Bollard pull is 60 tons ahead and 55 tons astern.

The tug will be assigned to one of the smaller west coast ports where Brusco provides ship-handling services. The hawser winch is a Markey Machinery DEPC-48-50HP. This is Markey's class II electric hawser winch and is the same model that has been specified for the last few Brusco tugs. It's a single-drum winch with a render-recover mode and a line pull of 27,820 lbs. at 268 feet per second, designed specifically for escort and ship-assist work.

Diversified is also building a tug for Shaver Transportation of Portland, Oregon. This 110-foot by 42-foot hull is a bespoke design from Jensen Maritime of Seattle to handle a wide range of tasks on the Columbia River from ship escort across the Columbia Bar to barge towing.

Shaver has selected a pair of GE 12V 250s, providing a combined 4,224 hp, to power the vessel, and Rapp Marine as the supplier of the two heavy-duty winches: a single-drum bow winch and a double-drum tow winch. "This is the biggest set of winches that Rapp Marine has delivered for a US tugboat" said Johann Sigurjonsson, CEO of Rapp Marine US.

The bow hawser winch will be used for ship assist and escorting duty on the Columbia River, out at sea and at the Columbia River bar, with the sturdy design capable of full render and retrieval up to 100 metric tons. The winch will be powered by one C32 Caterpillar Engine or, during smaller lighter jobs, smaller gen-sets will supply the power. The versatile tow winch features independently driven drums designed to hold either steel wire rope or synthetic rope.

US Navy Orders 24 Mini Tugs

The US Navy requires efficient and handy boats to support the warhorses. To meet this requirement John Myers of the Seattle-based naval architect firm Hockema & Whalen and Associates developed a versatile 30-foot by 15-foot tug, with a 5-foot, 6-inch draft that is now designated as "Work Boat Medium." Modutech Marine, of Tacoma, Washington has delivered the first of 25 tugs they are contracted to build in 25 months.

The Navy selected a pair of Cummins QSL 9 diesels, each delivering 285 hp at continuous duty. They are coupled to 39-inch by 36-inch propellers in Rice nozzles via ZF W325 gears with 3:1 reduction ratios. The combined 570 hp will give the 30-foot tugs a 7.9-ton bollard pull and a free-running speed of nine knots. The fuel capacity is 400 gallons. The wheelhouse has overhead windows for working alongside ships, and steering is improved with the use of a triple rudder system behind each nozzle.

Washington State Ferries director Amy Scarton christened the fourth and last Olympic-class ferry Suquamish in a ceremony in early January.

The decks are equipped with a variety of gear to handle any task – a pair of Bloom deck winches are mounted forward, port and starboard, with cheek blocks on the pilothouse. A towing bitt is mounted on the after deck and bollards on both sides. A 400-lb. davit can be moved to port or starboard mounts as required. D-Rubber fendering surrounds the hull, including the chine, and is mounted on the push knees that extend below the waterline. Heavy lifting eyes are built in to enable the tugs to be transported by road or water to navy bases anywhere in the world.

Another Tug for Dunlap

On January 20, Hansen Boat Company in Everett launched the 121.5-foot by 38-foot tug Sigrid Dunlap for the Dunlap Towing company of LaConner, Washington. It was designed by Hockema Whalen Myers Associates as a sister ship to the Phyllis Dunlap, built in 2001. It is ABS classed and SOLAS certified, and is powered by a pair of Caterpillar C175-16 Tier 3 diesels, with a total of about 5,350 HP. Fuel capacity will be approximately 150,000 gallons, to enable the tug to tow barges between Seattle to Hawaii for Aloha Marine Lines, which is part of Alaska Marine Lines. It is equipped with a Markey double-drum winch spooling 3,100 feet of 2.25-inch wire.
