Wärtsilä said it has booked an order in April 2017 to provide its Wärtsilä 31 main engine, the propulsion machinery and the auxiliary engines for a new state-of-the-art pelagic trawler under construction at a Norwegian shipyard. The vessel has been ordered by Research Fishing Co based in Lerwick, Shetland Islands. There is an option for a second vessel.

In specifying the Wärtsilä solutions, the customer cited the need for the latest technologies in order to optimize the total efficiency of the vessel. The Wärtsilä 31 engine has been recognized by Guinness World Records as being the world’s most efficient four-stroke diesel engine. This will be the first 12-cylinder version of this engine ordered.
In addition, Wärtsilä will supply the gearbox, the controllable pitch propeller with the Wärtsilä ProTouch propulsion control system, as well as one eight-cylinder and one six-cylinder Wärtsilä 20 auxiliary engines. Delivery of the Wärtsilä equipment is scheduled to commence in November 2017.
“The Wärtsilä 31 engine is in a class of its own regarding fuel efficiency and total cost of ownership. Its efficiency reduces exhaust emission levels, and provides extended intervals between service requirements. We are proud to have been selected to provide a complete package of solutions for this extremely modern fishing vessel,” said Stefan Wiik, Vice President, Engines, Wärtsilä Marine Solutions.
“This vessel has been designed to meet our needs well into the future. For this reason the machinery onboard has to be the best available, and we believe that by selecting Wärtsilä this requirement is achieved,” said Gary Williamson, Skipper & Co owner.
When delivered in the autumn of 2018, this 79.8 meter long Skipsteknisk designed vessel will operate in Scottish fishing grounds.

Virginia-Class Submarine Indiana Launched

The Virginia-class submarine Indiana (SSN 789) was launched into the James River at Huntington Ingalls Industries’ (HII) Newport News Shipbuilding division, the shipbuilder recently announced. The submarine was moved to the shipyard’s submarine pier for final outfitting, testing.

Over the next several months, they will work closely with the Indiana crew to bring this great ship to life. With the Navy’s recent increase in SSN force structure requirements from 48 to 66 submarines, the shipbuilders here at Newport News and at our teaming partner, Electric Boat, understand the importance of getting these highly valued ships delivered and ready for mission-tasking by our Navy leadership.
Indiana is the 16th Virginia-class submarine and the eighth that will be delivered to the U.S. Navy by Newport News. Nearly 4,000 shipbuilders have participated in Indiana’s construction since the work began in September 2012.
Indiana was moved out of a construction facility into a floating dry dock using a transfer car system. The floating dry dock was submerged, and the submarine was then launched into the James River. The approximately 7,800-ton submarine was moved to the shipyard’s submarine pier, where final outfitting stages, equipment performance testing, and crew certification will take place.
Virginia-class submarines, a class of nuclear-powered fast attack submarines, are built for a broad spectrum of open-ocean and littoral missions to replace the Navy’s Los Angeles-class submarines as they are retired. Virginia-class submarines incorporate new technologies and innovations that increase maneuverability, and firepower,  and stealth and significantly enhance their warfighting capabilities. These submarines are capable of supporting multiple mission areas and can operate at submerged speeds of more than 25 knots for months at a time.

Philly Shipyard starting four LNG Containerships, for new Hawaii line

Philly Shipyard Inc. (PSI) has begun construction of up to four new Jones Act compliant container type vessels and is actively promoting the formation of a new entrance into the containership trade between the U.S. mainland and Hawaii with a goal to enter service in 2020 as modern emissions standards make the islands old steam ships obsolete.

The new ships will be a continuation of the two Aloha-class 3,600 TEU containerships that Philly Shipyard is currently building for Honolulu-basedMatson Inc.

The Hawaii-Mainland trade route is currently serviced by two carriers, Pasha Group and Matson Navigation.

Philly Shipyard’s corporate parent is Aker ASA, a Norwegian industrial investment company with interests in marine assets including oil and gas and fisheries. The shipbuilding company has a successful history promoting new Jones Act vessel owners in the U.S. market, including the American Shipping Company and Philly Tankers.

In a prepared statement, PSI explained its rationale for launching the Hawaii-to-Mainland trade venture by explaining that the current carriers in the region are reliant in part on a group of near end-of-life steamships and that when stricter new MARPOL/ECA emissions regulations take effect in 2020, several of the older steam powered vessels now serving the route will be out of compliance.

Even if these aging steamships are modified, they would be less reliable and carry significantly higher operating costs than modern vessels in areas such as fuel consumption and manning and maintenance requirements.

PSI has commenced design work and procurement activities for the vessels, with the planned delivery dates for the first pair of vessels being in 2020, and the second pair 2021. They’ll be a direct continuation, PSI said, of the series of two similar 850-foot, 3,600-TEU “Aloha class” containerships that PSI is currently building for Matson Navigation’s Hawaii
