The Ulstein Hybrid Propulsion Concept
Ulstein Group has designed and built two new anchor handling and offshore support vessels with a new breed of hybrid propulsion system for shipowner Olympic Shipping. The new Ulstein hybrid propulsion concept has taken the potential of the rather complex hybrid propulsion concept to completely new levels of performance. The Ulstein hybrid propulsion concept combines the best properties of both DE and DM into one system. This includes DM attributes of higher efficiency and better performance at high loads, along with the DE trait of excellent fuel consumption at low loads.
ABB, Samsung Develop New Propulsion Concept
Playing off of each other’s strengths, ABB and Samsung announced a jointly developed propulsion concept for the new 12,000 TEU containerships developed by Samsung. Instead of being outfitted with a rudder, the ships will feature a CRP Azipod unit mounted directly behind the standard propeller. Located on the same axis, but without any physical connection, the pod’s pulling propeller will contra-rotate in relation to the shaft-driven main propeller. The arrangement will provide an estimated improvement of more than 10 percent in hydrodynamic propulsion efficiency.

Taking a Cruise on European Rivers with SCHOTTEL
About 40 European river cruise vessels are or will be equipped with a SCHOTTEL propulsion concept with four SCHOTTEL Twin Propellers STP 200. The concept was specifically designed for river cruise ships, and in five years has consistently gained acceptance with its numerous advantages such as low-noise, shallow draught, increased overall efficiency and energy efficient operation, SCHOTTEL said. Splitting the propulsion units from the conventional two to four Twin Propellers, reduces the draught of the ship to approximately 1.6 meters…

New Double-ended Ferry for Norderney
Ferries operated by Norden-Frisia AG have been serving the East Frisian island of Norderney for many decades. Navigation in these coastal waters poses special challenges: in some areas the waterway only leaves a few centimeters below the keel and the water contains a significant amount of swirled-up sand. A new sister ship of the double-ended ferry MS Frisia IV equipped with Voith Schneider Propellers (VSP) is to enter service in summer 2015. The shipping company again chose Voith Schneider Propellers as these are ideally suited for the specific operating conditions in shallow tidelands.
Agreement to Develop Gas-Fueled Ships
Wärtsilä and Samsung Heavy Industries (SHI) have signed a co-operation agreement to develop gas-fuelled merchant vessels. The intention is to jointly develop next-generation ships with efficient and competitive propulsion machinery concepts that meet or exceed the demands of future environmental regulations. The focus of the Wärtsilä/SHI joint study will be on utilizing liquefied natural gas (LNG) as fuel for operating vessels. This is especially relevant in Emission Control Areas (ECAs). Wärtsilä's input will be related to the propulsion machinery, with particular reference to large bore, dual-fuel engines combined with mechanical propulsion solutions. SHI will concentrate on the design of highly efficient vessels incorporating fuel storage facilities and gas-powered propulsion machinery.

Electronics Retrofit for Taiwanese Research Vessel
L-3 SAM Electronics has been awarded a contract to retrofit propulsion control and automation systems aboard the Taiwanese Navy’s Ta Kuan hydrographic and oceanographic research vessel. The 93-meter-long vessel, built by Fincantieri at its shipyard in Muggiano, La Spezia, Italy in 1995, carries out operations in domestic waters as well as the South China Sea on behalf of Taiwan’s governmental National Science Council and other research institutes. The completion of the retrofit is planned for later this year.
Is it the Answer? Hybrid Marine Propulsion
Soaring energy costs, more stringent emission regulations and conservation efforts are current topics in every media outlet. With crude oil prices around $120 per barrel, the question arises — what should the U.S. shipbuilding industry do to address those issues to its customers? Only a few years ago, consumption and efficiency were just two of many criteria when it came to the design of a new vessel. Today, however, they have great importance when a new design is on the drawing board. Before we answer the above questions, let's define the status quo. The vast majority of vessels built worldwide are outfitted with diesel propulsion and conventional shaft line. This method of propulsion for long haul trade has been proven over many years as the most efficient and cost-optimized solution.
ONR to Christen Advanced Electric Ship Demonstrator
The Advanced Electric Ship Demonstrator (AESD), Sea Jet, funded by the Office of Naval Research (ONR), is a 133-ft. vessel located at the Naval Surface Warfare Center Carderock Division, Acoustic Research Detachment in Bayview, Idaho. Sea Jet will operate on Lake Pend Oreille, where it will be used for test and demonstration of various technologies. Among the first technologies tested will be an underwater discharge waterjet from Rolls-Royce Naval Marine, Inc., called AWJ-21, a propulsion concept with the goals of providing increased propulsive effiency, reduced acoustic signature, and improved maneuverability over previous Destroyer Class combatants.
