Controllable Pitch Propeller Systems News

Damen Naval has selected Kongsberg Maritime Sweden to deliver controllable pitch propellers and shaft lines for the four Anti-Submarine Warfare (ASW) frigates for the Netherlands and Belgium.As part of this contract, Kongsberg will supply four shipsets of its controllable pitch propeller systems and associated equipment including blades, hubcaps, hubs, and shaft lines.The four ASW frigates will replace the current Karel Doorman-class multi-purpose frigates. They will be deployed for a wide variety of tasks, with anti-submarine warfare as their main purpose.

Norway's Kongsberg Maritime has won an order for six sets of controllable pitch propeller systems from South Korea's Hyundai Heavy Industries for installation in six new 94-meter offshore patrol vessels for the Philippine Navy.Each propulsion set will consist of twin Kongsberg Kamewa Controllable Pitch Propeller (CPP) 86 A/5 D-B systems, as well as shaft lines, hydraulic power units, local operating panels, and accessories. The first shipset will be delivered in August 2024.The six new offshore patrol vessels (OPVs) are part of a major upgrade to Philippine naval capacity.

Rolls-Royce and the Defense Production Act Title III office will invest millions of dollars to upgrade the company’s capability and capacity for U.S. Navy ship propulsion components in its facility in Pascagoula, Miss.The DPA Title III office has already agreed to invest $22 million for equipment, with Rolls-Royce making an additional investment for building improvements, supplemented with support from Jackson County and the state of Mississippi.Naval components manufactured by Rolls-Royce at Pascagoula include controllable-pitch propeller systems, fixed pitch propellers, and water jets.

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. The scope of Wärtsilä’s supply, which comprises two eight-cylinder Wärtsilä 32 engines specially tuned for dredging operations, two controllable pitch propeller systems and two tunnel thrusters, provides the required power and manoeuvrability.

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. The yard is located on the River Clyde in Glasgow. "This project highlights the fact that high-end, technologically advanced commercial shipbuilding is again present in Scotland.

Wärtsilä has developed propulsion systems that are capable of operating with Environmentally Acceptable Lubricants (EALs) and comply with the US Vessel General Permit 2013 (VGP-2013). Wärtsilä is among the first marine propulsion solutions suppliers to achieve this compliance for complete propulsion packages. For vessels operating in US waters, VGP-2013 mandates the use of EALs in all oil-to-sea interfaces unless technically unfeasible. VGP-2013 was issued by the US Environmental Protection Agency (EPA) and is applicable to all vessels sailing in US coastal waters. Wärtsilä began work on developing an effective solution in 2013, working together with numerous EAL suppliers.

Ferries for Alaska’s harsh conditions, built in Alaska by Alaskans. Vigor and Elliott Bay Design Group team up for a winning combination as the new Alaska Class Ferry Project takes shape. With its network of islands and fjords, rugged mountains and spectacular tidewater glaciers, Alaska’s Inside Passage may make a perfect summer cruise destination, but locals can’t choose when they travel. So when Alaskans need transport, the Alaska Marine Highway System (AMHS) must find a way to move them.

German propulsion giant Schottel looks back at five decades of  controllable-pitch propeller (CPP) development. CPPs 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 additional 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…

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.

Scana Industries USA, Inc. has opened an office in La. to promote their propulsion line in the Americas markets which covers the United States, Mexico, and Canada. The office will be located in Mandeville and will be managed by Dan Gaiennie. Gaiennie has over 28 years experience in the marine industry in both technical and operation roles. With the acquisition of ABB Zamech (manufacturer of thrusters and CP-propeller), Scana Industries has formed the Scana Propulsion Group which manufactures and services controllable pitch propeller systems up to 20…

Schottel ended the year 2003 with record sales. With 550 employees worldwide, the company continued the previous year’s trend, achieving sales in the new systems and service sectors totalling 90 million euro (2002: 81 million). Sales for the group were thus increased by 11%, and once again exports accounted for some 80% of the total. The extremely satisfactory volume of incoming orders in the last 12 months, amounting to some 88 million euro, means that 42 million euro of orders are on hand for the year 2004. Of particular significance are the latest worldwide sales successes in the areas of tug propulsion systems, offshore supply vessels, cruise ships, research vessels, ferries and military vessels.

German engineers have strengthened the Schottel offering through the development of a propulsor which melds technical design and performance features of the company's proprietary, azimuthing Rudderpropeller series with those of electric podded drives. The resulting hybrid system, known as the Schottel Combi Drive (SCD) and distinguished by its compactness and inboard placement of the integral electric motor, has been designed for unit power applications in the 1,900 to 3,800-kW range. The innovative new product employs proven mechanical elements from the Rudderpropeller design and the latter's optimized-efficiency, Twin-Propeller (STP) version.

With a revised product range and a new corporate structure, Germany’s Schottel announced that its headquarters in Spay/Rhine and Schottel Antriebstechnik GmbH in Wismar have been merged to form the new Schottel GmbH with its registered office in Spay and branches in Wismar and Hamburg. Schottel Schiffsmaschinen GmbH, which is also based at the Wismar location, will continue to develop and manufacture controllable-pitch propeller systems as an independent company. The core competencies of Schottel GmbH are the development, production and servicing of steerable propulsion and maneuvering systems such as the Rudderpropeller and its electric variant the Combi Drive, the Schottel Pump-Jet and the SCHOTTEL Transverse Thrusters.
