Defying the boastful biggest, fastest or strongest routine (after all, who needs that?), the two stars of this story measure a dapper 665 mm inside diameter. They have chipped a colossal 33.4 per cent off the previous 1,000 mm Optima entry level model. Given the 8,000 mm inner diameter of the biggest Optima propeller nozzles, or the average size of any DMC nozzle for that matter, our new 665 mm milestone twins could almost be considered precision mechanics. “They definitely brought dear, fine engineering and precision manufacturing to our teams indeed”, Aart Vogelaar, Sales Manager Damen Marine Components enthuses. The two record-breaking 665 mm nozzles are spectacular also, as they were built for a 50-foot (15 meter) yacht. They were commissioned from Damen Marine Components by a third-party (non-Damen) manufacturer of propulsion systems. “Our clients had to install DMC Optima propeller nozzles by customer specific requirement from the owner, who, in addition, wanted his 50 foot 11 knot boat to have two propellers. He must be an expert, considering this explicit and uncompromising selection and configuration, including a stainless steel inside ring. Possibly a tugboat or inland waterway vessel captain. But definitely an expert”, Aart Vogelaar adds. Lowest noise and vibration The owner must be aware of both the Optima’s unparalleled characteristics for reducing both noise and vibration, and for its propelling performance. With its own special inside profile, the nozzle type was patented by DMC back in 1998 already. Thousands of units have since established the Optima’s reputation as a nozzle renowned for combining high comfort with performance within its specific operational range. “Its profile was designed for an optimum ratio between engine output, fewer revolutions and thrust, both forward and reverse”, Vogelaar specifies. “As this includes modest sailing speeds, this model - with the matching propeller pitch - is widely deployed in inland waterway vessels, Stan tugs, push boats and hopper dredgers. Its noise-vibration-thrust performance is the Optima’s acknowledged trademark throughout the shipping industry. This is no illusive claim of ours, it’s a fact, full stop.” Small hands DMC’s Optima nozzles usually have an L/D 0.5 ratio (length = 0.5 x diameter) for dredgers, Stantugs or inland waterway vessels, and L/D 0.6 for push boats. The river yacht soon to boast the world’s smallest nozzles, will feature L/D 0.4 to still safeguard ‘crew comfort’ at its somewhat higher 11 knot speed. Like each and every DMC nozzle, these two have been engineered separately at the DMC center in Hardinxveld-Giessendam, Netherlands. Vogelaar explains: “No two vessels are the same, not even with identical dimensions, unless they are carbon copy sister ships. Consequently, every nozzle we produce, will have had dedicated engineering first, for optimum output. So this wasn’t just because these two measure only one twelfth of our biggest Optima’s. I love saying this. The two mini’s weigh only 188 kilos each. No, at…

The offshore industry particularly, is driving demand. Steef Staal, DMC Managing Director, says: “We had a fantastic year in 2012 and it is still looking positive this year, so it was vital to extend our production capacity. There has been much more demand for nozzles from the offshore industry but also for other parts. Increasingly clients are using Dynamic Positioning, which is leading to more demand and existing clients have also seen significant growth.” Already this year DMC has expanded its production capacity in Poland with a new 3,000 sq m covered facility in Elblag, near Gdansk. This joins DMC’s existing 30,000 sq m site in Gdansk. Additionally, DMC has been investing in new pipe bending and welding equipment. The company is also undergoing an expansion in Suzhou, China where its other main production facility is based. With the substantial growth and new products, it is necessary to have a much larger facility in China as well. The new facility will probably be built near Shanghai. Mr Staal is hopeful that the new production plant could be fully operational by the end of the year. The second spinning machine on order is set to be installed in China in the first half of 2014. Closer to home, with the increase in production, DMC is also increasing staff numbers and its headquarters in Hardinxveld-Giessendam are undergoing a refurbishment to accommodate this. Commenting on the future, he says: “Our quality is being recognised worldwide, and because we are producing in lower cost countries we can remain competitive but still retain top Damen quality. We have a very busy year coming up, with a healthy orderbook. And we are very much looking forward to our expansion in Poland and building a new facility in China.” Recent news

The rudder covers an area of approximately 54 SQM, which makes it the largest rudder Van der Velden Marine Systems ever built since her existence almost 50 years ago. The MSC Athens is the first in a series of 11 vessels to be built at Sungdong shipyard, which will all be equipped with Van der Velden rudders. The 300 metre long eco-friendly vessel has been fitted with the largest Timon flap rudder ever delivered by Van der Velden Barkemeyer. The 300 metre long eco-friendly vessel MSC Athens has been fitted with the largest Timon flap rudder ever delivered by Van der Velden Barkemeyer. The 54m² rudder is provided with Asymmetric Rudder Technology (ART™). ART™ is a special rudder design that has been developed to improve propeller flow. A special layout modifies the profile above and below the centreline of the propeller in such a way that effects of the rotation of the propeller slipstream are countered. This expands the cavitation-free rudder angle and reduces drag, increasing speed or improving fuel consumption. Reduced rudder cavitation also gives an extended life span to rudders and shaft bearing systems. Low vibration and noise levels are an additional bonus.Rotary Vane steering gear for largest vessel Jaya Shipbuilding and Engineering In Singapore, Jaya Shipbuilding and Engineering delivered its largest and most advanced vessel built so far. The 85 metre Jaya Supreme, to be renamed Atlantic Kestrel, was delivered to its Canadian owners, Atlantic Towing Limited, at the end of November. The Jaya Supreme is one of the most sophisticated offshore support vessels ever built in Singapore, and has been equipped with Commander rotary vane steering gear. A key benefit of the rotary vane steering gear is that the rudder angles of up to 2 x 65º give greater flexibility when choosing the design and type of the rudders. Enhanced manoeuvrability and increased control in harbours are the result. Recent news

Combining decades of knowledge has resulted in the development of a highly effective and efficient propulsion package: the Energy Saving Package. Due to rising fuel costs and the highly competitive ship market, ship owners and charterers attach more and more importance to efficient and fuel saving operation of their ships. With slow steaming and a number of fuel saving products which have been (re-)introduced into the market within the last years, ship owners and operators are going to reduce their operation and maintenance expenses as much as possible. With the Energy Saving Package, MMG and Van der Velden® provide a smart maritime solution for this trend. Energy Saving Package: A tailor-made smart maritime solution The Energy Saving Package consists of a tailor made propulsion package which meets the customer’s requirements. MMG and Van der Velden® combine the advantages of an optimised, highly efficient fixed pitch propeller with an asymmetric leading edge rudder with a propulsion bulb and adapted hub caps. Conjointly with the ship owner, the naval architect and/or the yard, front end engineering design (FEED) will exactly identify the needs according to the ship’s operational profile and optimise the propeller rudder-arrangement depending on the particular criteria, such as fuel efficiency, good and effective manoeuvrability, minimising of cavitation and vibration, and low maintenance effort. This results in an optimised propeller geometry and a slip stream adapted rudder geometry . A propulsion bulb, junction caps or boss cap fins are part of the solution. Benefits and applications The Energy Saving Package provides the efficient and fuel saving ART™ rudder, ensuring highly effective manoeuvrability. A special lay-out modifies the profile above and below the centreline of the propeller in such a way that the effects of the rotation of the propeller slipstream are countered. This expands the cavitation-free rudder angle and reduces drag (increasing speed or improving fuel consumption), while the well-designed propellers prevent tip cavitation. Finally, the Costa bulb, junction cap or boss cap fins prevent hub vortex losses and cavitation. The new Energy Saving Package is currently available for fixed pitch propeller systems by MMG, in combination with Van der Velden® full spade rudders. Both new design and retrofit are possible.

Tunisia’s state owned ferry company CoTuNav has chosen the Korean shipyard DMSE to build this new RoPax cruise ferry, which will be one of the biggest ferries in the Mediterranean when delivered in May 2012. What’s more, with a maximum speed of 30 knots, it will also be one of the fastest sailing ferries in the world. The ferry is designed with two separate engine rooms with the propeller shaftlines having different lengths of well over 40 metres. The final propeller blade design will be hydrodynamically optimised and carefully balanced with a special focus on propulsion efficiency, low noise, and cavitation levels.The Timon flap type rudders installed on the TANIT optimise speed and course corrections and reduce cavitation and vibration. The rudder profile is based on the well-known HSVA and NACA profiles and is very suitable for fast vessels requiring a high manoeuvring performance. Because of the flap, turning circles are smaller and course corrections can be made more efficiently. The two Timon rudders are provided with Asymmetric Rudder Technology (ART™). ART™ is a special rudder design that has been developed to improve propeller flow. A special layout modifies the profile above and below the centreline of the propeller in such a way that effects of the rotation of the propeller slipstream are countered. This expands the cavitation-free rudder angle and reduces drag, which contributes to the ship’s speed abilities. Reduced rudder cavitation also gives an extended life span to rudders and shaft bearing systems. Low vibration and noise levels are an additional bonus.The ship will measure 210m in length and 30m in width with a design speed of 27.5 knots and a capacity of 1060 vehicles and 3200 passengers. The ferry will service CoTuNav’s routes between Tunisia, Italy and France and will include a shopping centre, restaurants, swimming pool and multiple entertainment facilities. Through this new ship CoTuNav seeks to consolidate its position in the Mediterranean sea transport, to further develop the quality of its services and to contribute to the promotion of Tunisian tourism.

This makes the process much more efficient and environmentally friendly. The new Single Weld Nozzle Spinning Machine can deliver nozzles up to 5.3 m at short notice. Based in Hardinxveld in the Netherlands and part of the Damen Shipyards Group, DMC has invested in new spinning machinery for its facility in Gdansk. The spinning machine can produce nozzles with an inside diameter ranging from 1,000 mm to 5.3 m outside. Mr Steef Staal, DMC Managing Director, says: “The new spinning machinery, developed in the past two years, makes the production of nozzles much easier and gives an improved end product, because there is only a single weld seam on the inner side of the nozzle. Manufacturing the complete inside of a nozzle in one go is very special.”Capacity The spinning machine can produce nozzles with an inside diameter ranging from 1,000 mm to 5.3 m outside. Using a completely automated system, the machine can handle stainless steel, duplex, steel and special steel materials. The new machine is also able to handle the demand for shorter delivery times, emphasizes Mr. Staal. “Uncertainty in the market often means that companies order equipment at the very last minute and this means that lead times and delivery times are getting shorter. With this machine we adapt to that process.” Under the traditional construction method, the inner side is constructed from several small welded parts. This is now history and the new method results in a much smoother surface. The new machine is already proving very successful with both existing and new customers. Emission reduction Propeller nozzles are a sustainable product by definition, because they significantly reduce fuel consumption and thus cut down on CO² emissions. However, the new production method is even more environmentally friendly. “Because there is less welding and grinding this method saves energy and emissions,” Staal says. In addition, the new machinery saves production time and enhances our stable price/quality ratio, making it more cost efficient. In addition to producing nozzles, DMC advises customers on various related topics, e.g. nozzle installation methods, in order to deliver a comprehensive solution to its customers. Recent news

The research & engineering department is constantly working on product innovation and checking on wider applications of existing products. In cooperation with Damen Shipyards Gorinchem, a nozzle has been developed which can be applied in closed cooling water systems. Background is, that out of the smaller getting engines more and more power is being squeezed. "This means you simply need more cooling capacity," according to DMC-director Steef Staal. Cooling water flows from the main engines through the construction of the nozzle. This application of nozzle cooling has the advantage that, by rotation of the propeller, the flow rate of the (sea)water along the nozzle is always high, particularly when the main engines run full powered. This guarantees high efficiency cooling! The first ship with nozzle cooling has been delivered to the customer. The performance of this nozzle has extensively been tested in the Netherlands and in the warm Middle East. Other nozzles will be tested this year. Recent news
