Voith Delivers First U.S.-Built VSP Units

The first two American-made Voith Schneider Propeller (VSP) units have been delivered and installed in the Rodanthe ferry.Rodanthe is a ferry to be operated by the North Carolina Department of Transportation (NCDOT) and used in its service to the Outer Banks, a string of barrier islands between North Carolina and the Atlantic Ocean.“With the new VSP units installed, the Rodanthe will offer years of smooth, efficient service to the islands. By linking steering and propulsion together, the VSP allows for fast response and precision movement in even the roughest of waters.

Wartsila Propulsion System for New NMDC's Dredger

Wärtsilä supplied the full propulsion package for National Marine Dredging Company's (NMDC) new, state-of-the-art Trailing Suction Hopper Dredger (TSHD) launched in September. The 6,000 m3 capacity TSHD was designed by the IHC shipyard in the Netherlands in close cooperation with NMDC. The customized solution combines a shallow draft and a deep dredging depth with high manoeuvrability. The vessel has been specially designed to operate in high ambient temperatures, and the Wärtsilä machinery is capable of operating efficiently in such conditions.

Stone Marine, NGC Marine Launch Joint Company

Propeller design and manufacturing company Stone Marine Propulsion has joined forces with NGC Marine of China to form a new supplier of propulsion solutions and marine gearbox equipment.

New Bronze Propeller for Arctic Ops

Finnish company TEVO Oy said it has developed a cost-effective alternative for steel propellers. The result of a large product development project, TEVO said it can now design and manufacture an optimal bronze propeller construction for 1A Super (PC-6) class. A bronze propeller designed for 1A Super class with optimized efficiency and noise characteristics has been verified in full-scale sea tests in the northernmost part of the Baltic Sea, particularly in harsh ice conditions of the northern part of the Gulf of Bothnia.

Wärtsilä Propulsion for First UK Dual-fuel Ships

he first ever UK domestic dual-fuelled new build vessels will feature fully integrated Wärtsilä propulsion machinery packages. Wärtsilä will also supply extended engineering and site support services. The two ships, both 102 metre long ro-ro passenger ferries, are being built for Caledonian Maritime Assets Ltd (CMAL) based in Port Glasgow, Scotland. The contracts with Wärtsilä were recorded in December 2015. Besides being the first dual-fuel vessels for CMAL, they are also the first ever dual-fuel ships to be built in the UK. These will be built by Ferguson Marine Engineering Ltd.

20+ Year COMPAC Wear in Canadian Navy Patrol Frigates

Press release - The Royal Canadian Navy (RCN) is no stranger when it comes to using Thordon COMPAC propeller shaft bearings in its vessels. Over two decades ago, in May 1992, the RCN (then known as the Canadian Navy) back-fitted its lead frigate, HMCS Halifax, with Thordon COMPAC. The first of 12 new patrol frigates, the RCN selected Halifax as the exemplary ship to set a precedent for her sister ships and represented what the RCN then deemed to be “the most advanced warship in the world”.

Van Oord Orders Two New Dredgers

Rotterdam-based dredging and marine contractor Van Oord has recently ordered two trailing-suction hopper dredgers as part of its continuous investment program. The vessels will be constructed at CNN LaNaval Shipyard in Sestao, Spain with delivery dates scheduled for 2017. Each vessel will feature a complete MAN Diesel & Turbo propulsion package with MAN 6L48/60CR engines, RENK gearboxes with PTO, MAN Alpha CP Propeller systems, AHT (Alpha High Thrust) Propeller nozzles and MAN Alpha AT3000 propulsion-control systems.

Six COMPAC water-lubricated propeller shaft bearings will supplied to Fincantieri for installation to MSC Seaside

Thordon Bearing's Compac to Keep Seaside Clean

MSC Cruises has specified Thordon Bearings’ COMPAC water-lubricated propeller shaft system for the first of two (plus option) Seaside-class cruise ships currently under construction at Fincantieri’s Monfalcone yard. The 154,000grt twin-screw vessel, the largest cruise ship ever to be built by the Italian yard, will be equipped with six COMPAC bearings in bronze carriers with tapered keysets to fit 664mm shaft diameters. Thordon’s Commercial Director, Andy Edwards said, “The ship, developed entirely by Fincantieri, represents a genuine evolution of the cruise ship.

State of the art SCHOTTEL Controllable Pitch Propeller

50 Years of Schottel Controllable Pitch Propellers

Controllable-pitch propellers have been developed and produced on the Baltic coast of Germany since 1962 – initially in Rostock, and then in Wismar from 1964. The first units were manufactured for 86 freezer-trawlers of type Tropik for the Soviet Union. Four further types were produced for GDR fishery vessels. The first years of controllable-pitch propeller production in Wismar centered on systems with a power rating of 1,930 kW for 199 freezer-trawlers of type Atlantik. A total of 230 controllable-pitch propeller systems were delivered up to the end of 1969.

Schottel SCP controllable-pitch propeller systems of the 5-X series are available with  power ratings from 1,000-20,000 kW.

Wärtsilä Launch Stern Tube Bio Seal™ Ring

The Wärtsilä Bio Seal Ring is the first seal on the market that works with Environmentally Acceptable Lubricants (EAL), sometimes known as bio-degradable oils, for a lifetime of at least five years. Conventional seal rings are recommended to be changed at two and a half year intervals. The benefits offered by the Wärtsilä Bio Seal Ring to ship owners and operators are both environmental and economic. The extended operating life expectancy has a significantly positive impact on dry-dock scheduling and related costs.

Contrapel's Above the Water-Line Propeller System

Marine propulsion research & development company, Contrapel Ltd has released details of its new propulsion system for boats – the system set to make future boats more economical, manoeuvrable, safer, stronger and better for the environment. The high-speed propeller was invented over 170 years ago and has dominated the propulsion market ever since. Despite 60 years of development, water-jets have struggled to make significant inroads. Shown to an enthusiastic marine industry for the first time at the recent Auckland On Water Boat Show, the Contrapel Hybrid Drive is about to change that.
