NASA’s ‘Curiosity’ rover touched down on Mars in early August after travelling563 million kilometers through space. Siemens is proud to have played a role in its unique journey. The scientists and engineers at NASA developed the rover usingstate-of-the-art PLM (Product Life-cycle Management) software from Siemens. ‘Teamcenter’ (data management and collaboration) and ‘NX’ (computer-assisted design) were ideal to digitally design and virtually assemble the vehicle and simulate its functions well before the very first physical prototype was built. The software helped ensure all components would fit together, operate properly and withstand the harsh conditions of the mission. In all, 250 NASA engineers worked with Siemens PLM software making it the most spectacular application to date from Siemens’ diverse portfolio of industry-specific software.

With smarter and more complex products coming to market, production is almost inconceivable without the use of IT. It enables products to be assembled virtuallyand then extensively tested in simulated conditions even before the first prototypes are made. IT increases production flexibility and quality. It drastically reduces development- and market-introduction time for new products. In other words, customers save money, time and resources. These are all critical success factors for manufacturing enterprises competing globally.

The complexity and cost of vessels place enormous pressure on designers, engineers and production teams to improve productivity. Moreover, the cost of maintenance can be several times the initial outlay, which means total ownership cost is just as important as operational factors, such as speed, endurance and payload. Due to these challenges, leading commercial shipbuilders have realized that they must create a seamlessly integrated and synchronized environment linking designers, engineers, production specialists and support teams, including partners and suppliers, to optimize total performance and maximize life-cycle productivity. Siemens PLM software answers these challenges with a comprehensive portfolio spanning all operations and phases of a commercial ship’s life. From concept and design to initial production and lifetime maintenance. Our commercial shipbuilding solutions create and synchronize the complete and current technical definition of a ship. The end result? Our customers design and operate vessels that are more environmentally friendly, safe and profitable.

Innovating businessWe are also proud to announce several new orders – see next page – based on our new propulsion concept BlueDrive PlusC, which lowers shipowners’ life-cycle costs and emissions of greenhouse gases. Furthermore, by using new battery technology in propulsion systems that store energy in electric-propulsion plants, fuel consumption and environmental impact are reduced through improved operation of diesel and gas engines. It’s innovations such as these, combined with a proven product portfolio,which help Siemens retain its place as a world leader in ship technology.

Lower maintenance costs With BlueDrive PlusC, diesel engines’ power/speed capability is optimized to different vessel operations, such as docking, transit, slow steaming, dynamic positioning, which means operation time at rated speed is cut to a minimum. This reduces engine strain, vibration and noise. The result is lower maintenance costs and reduced risk of significant repair.

Greenhouse gas emissionsTests show that variable speed diesel-electric propulsion engines emit less greenhouse gases than dual-fuel engines operated at constant speed. Only LNG-fueled engines achieve slightly lower emissions of CO2

and NOx. By running diesel engines at variable speed, combustion is improved andexhaust temperatures are kept high, which secures operation of the selective catalytic reduction (SCR) process. As variable-speed operated diesel engines achieve favorable combustion, NOx emissions are much lower than dual-fuel.

Fuel savingsOperating diesel engines at variable speed reduces fuel consumption. In fact, a study of a platform supply vessel shows variable-speed operated diesel engines use less fuel than dual-fuel and LNG-operated engines

What is BlueDrive PlusC?

even at constant speed. BlueDrive PlusC also has the highest electric power plant efficiency from shaft extension of the diesel engines to propellers, compared with other electric-propulsion solutions.

Reduced spaceDue to technological advances, BlueDrive PlusC needs less space than comparable systems. A typical figure is 30% less compartment area for electric equipment compared with other conventional electric-propulsion concepts. Siemens suggests division of space as follows: • Engine room (generators)• Switchboard room (BlueDrive PlusC switchboard) • Thruster/propulsion rooms (electric motors)

Frequency converters for propellers and thrusters are now part of the BlueDrive PlusC switchboard. They are located in the switchboard room, instead of being spread around in different propulsion and thruster rooms. This means only one room with clean and dry air is necessary to secure long life of electric-power electronics, control equipment and switchgear. In addition to space reductions, installation is also simplified.

Siemens’ diesel-electric locomotive with two variable-speed diesel-generator sets and variable-speed bogies.

Only one compartment for all switchgear and frequency converters is required.

BlueDrive PlusC is Siemens’ response to the challenges of operating high-speed diesel

engines in electric-propulsion plants. high-speed running caused vibration and break-

downs. the goal was to slow engine speed when lower power was needed to reduce

life-cycle costs. bluedrive plusc also benefits operation of medium-speed diesel engines.

Siemens develops and maintains energy solutions for all vessels, from platform-supply to anchor-handling vessels and drill ships to tugs. Siemens size and substantial global presence works to its advantage as many larger offshore-vessel operators prefer well-established suppliers with extensive global networks. They like the scalability and reliability of Siemens’ solutions and see the advantages throughout the building process and during the vessel’s lifespan of partnering with such a large global company.

Standard benefitsA fleet with standardized solutions has many operational and cost-saving advantages, such as:

• Synergies from shared solutions cut project costs with less time used on planning, design and engineering

Offshore focus• Proven solutions give confidence• Increased crew flexibility with less training costs due to common systems• Improved operational safety and efficiency as crews’ knowledge and experience are easily transferable between vessels• Cost-effective life-cycle management with reduced administration, improved service terms and reduced stocks of spare parts

Energy optimization To achieve optimum engine speed under all load conditions, BlueDrive PlusC has integrated management and control through the Siemens Energy Management System EMS 300C. This control system works in both local and manual modes, as well as remotely in automatic mode.

The energy management system ensures that gensets are working at the speed and load that deliver the lowest fuel consumption and greenhouse gas emissions. Engine speed and load are successfully controlled and optimized through careful monitoring of the entire propulsion system. This capability makes BlueDrive PlusC the world’s most environmentally friendly propulsion solution.

EMS 300C is an integrated control and monitoring system for optimizing energy use through control of the following:• Generator control unit, which controls and monitors engines and generators• Propulsion control unit, which controls and monitors thrusters and propellers• Remote control system, which remotely controls and monitors vessel speed and propeller thrust • Intelligent load controller, which controls bus-tie breakers

To maximise safety, reliability and flexibility these units connect via a redundant network for information exchange. They work independently of each other, which prevents a malfunction in one tripping the entire system and disabling the vessel.

The ship is normally operated from the bridge via the remote control system (RCS). In the RCS, different operational modes are chosen with pre-set points for propeller speed, power and pitch. For azimuth thrusters, rotation angle (thrust direction) is also controlled.

BlueDrive PlusC energy management system

The generator control units – there is one for each generator – monitor and control generators in all operational modes.

The intelligent load controller controls and monitors the electronic bus-tie switch and associated motor-operated isolation breakers.

Speed optimizationEMS 300C automatically optimizes engine speed to the corresponding load. Engine load curves are programmed into the generator control unit for this purpose.By comparing energy consumption, battery energy levels (if relevant) and power demand in different operational modes, EMS 300C calculates power demand for every genset. The value is sent to each generator control unit to enable individual speed, power and voltage optimization for all running gensets. This means that connected gensets are run with different speed and load (asymmetrical load sharing) if most economic.

The remote control system exchanges information with the propulsion control unit to give set points for propeller speed and power and receive propeller limitation signals for max./min. speed, acceleration, retardation times, etc. The remote control system then routes this information to EMS 300C.

Reliable and redundantIn case of main component malfunction in the ship’s power plant, all necessary action is taken to ensure uninterrupted energy flow and avoid possible damage.

There is one energy management system controller for each bus-bar section, supplemented by SIPROTEC Digital Generator Protective Relays. Renown SIMATIC S7 automation components are used to ensure spare-part availability

The BlueDrive PlusC propulsion system supplies all power through frequency

converters. These generate smooth and clean voltage independent of generator

frequency. Siemens utilizes this feature and runs gensets with variable speed.

globally. A redundant power supply for SIMATIC equipment and main CPUs are supplied for each bus bar.

The generator protection unit/measuring transducers are stand-alone units independent of the SIMATIC S7 system. Consequently, a fault in SIMATIC S7 does not affect the generator protection system and the possibility for manual operation.

EMS 300C requires an additional independent diesel-protection system for over-speed, lubrication oil, pressure, etc.It has only secondary diesel-protection functions, such as generator breaker trip in case of shutdown alarm, from the diesel-protection system.

EMS 300C is designed for an external engine-speed control system. The engine is delivered with speed control where speed reference settings are preformed. Load is

actively shared between generators.EMS 300C is designed with a CPU solution, where each generator is monitored and controlled separately. CPUs are connected in redundant topology, so failure of one does not have a critical effect on BlueDrive PlusC’s functionality.

A design principle for EMS 300C is simplicity, which means that focus is solely on the main power plant.

Clear for battery operationBlueDrive PlusC also contains Siemens’ well-proven, ultra-fast generator power adaption (GPA) generator load-reduction system. GPA reduces propulsion power instantly if a generator overload is detected. This is particularly beneficial if a generator shuts down to avoid black-out. In addition to GPA, a generator load limitation (GLL) system is provided.

This system uses voltage reference to limit generator load when the engine is running on reduced speed. The GLL takes effect when the generator is running in parallel with batteries or other generators with spare capacity. Active GLL increases engine speed if bus-bar voltage drops too far. It also ensures that energy is quickly provided from batteries.

Starting gensets takes much more time than bringing batteries online. Batteries provide energy instantaneously and prevent load reduction during start-up of a standby genset. When load increase is only temporary, starting a new genset can be avoided altogether.

Siemens is proud to play a part in this

development.

World’s first battery-driven ferry

Norled has won the contract to build and operate the world’s first battery-driven ferry

on a route between Lavik and Oppedal in southwest Norway. Siemens has worked with

the owner and its shipyard, Fjellstrand, to design the ferry’s propulsion system using

BlueDrive PlusC with battery power. Together with a superlight aluminium design,

the propulsion system is vital in the project’s success.

Norled’s vessel is a global first for environmentally friendly battery-driven ferries.

Østensjø Rederi operates a fleet of PSVs, multi-purpose vessels, ROV/sub-sea vessels and tugs from its offices in Haugesund, Norway.Illustration shows the Edda Ferd with Siemens’ BlueDrive PlusC propulsion system.

Siemens’ BlueDrive PlusC propulsion system is installed in Østensjø Rederi’s signature vessel by Spain’s Astilleros Gondan shipyard. Prior to delivery, the system underwent design reviews and full-scale short-circuit testing to gain Approval in Principle from the class society. Following approval, the entire system was function tested in a test bed before final test acceptance certification.

The main generators and diesel engines were mounted at MaK’s factory in April 2012. Subsequent testing established the following:

• All expected fuel-saving benefits at variable-speed operation were confirmed.

A true hybridØstensjø Rederi’s platform support vessel (PSV) Edda Ferd was launched in October.

after final fitting, she will arguably become the world’s most environmentally

friendly pSV.

• Exhaust temperatures at variable speed were maintained at correct levels to enable SCR catalyst operation down to 6% load. Compared to fixed-speed operation where SCR does not function under 40 to 45% load, this substantially reduces NOx emissions.• Genset-with-load acceleration rates were more than adequate for rapid load changes during dynamic positioning (DP) operations.• Low noise levels from engines at variable-speed operation with low load. As rpm decreases, acoustic noise levels in the machine room are significantly reduced. The extent of the reduction surprised all involved and will especially benefit crew during DP operations.

Energy storage modulesThe Edda Ferd is also being fitted with Siemens energy storage modules by integrating lithium batteries in the BlueDrive PlusC main propulsion system. Even though diesel engines’ acceleration rates are more than sufficient, batteries enable engines to run at lower rpm settings as they ‘absorb’ transient load steps. In addition, batteries provide energy for DP-fault situations that reduce spinning (generator) reserve in the system. By combining the variable-generator speed and energy-storage modules the Edda Ferd becomes a true hybrid.

The journey across New York’s bay from Staten Island to Manhattan is one of the world’s great ferry rides. It’s a trip taken regularly by locals and tourists alike and provides the only sea link between New York’s fifth borough and the mainland. Affording iconic views of the city’s skyline, including the Statue of Liberty and Ellis Island, it is the U.S.’s busiest ferry route with 20 million or so passengers travelling annually. One reason, perhaps, is that the five-mile, 25-minute ride is free.

The ferries – there are eight of them – are operated by the New York City Department of Transportation (NYDOT). Split into four classes, the newest is known as the ‘Molinari class’ after Guy V. Molinari, a former member of the US House of Representatives for Staten Island’s district and later a borough president of Staten Island. There are three Molinari-class vessels: MV Guy V. Molinari, MV Senator John J. Marchi and MV Spirit of America, all built by Manitowoc Marine Group in Wisconsin. Even though the first came into service as

The MV Senator John J. Marchi is named after the Staten Island senator who represented the island for 50 years.

late as 2005, their design retains the charm and ambience of the classic New York ferries.

In 2010, Siemens USA, together with Siemens Norway, were commissioned by NYDOT to survey and review the MV Senator John J. Marchi. The vessel, equipped with another diesel-electric propulsion system, was giving NYDOT a number of problems, including unreliable propulsion frequency converters and bridge control switch, redundancy issues, poor user-friendliness and lengthy repair lead times.

The survey led to a contract to upgradethe ‘Marchi’ and dialogue on rebuilding the two sister vessels. The current contract’s scope covers four new BlueDrive frequency converters, a new remote control system and an upgrade of the main switchboard to a generator power-adaptation system. The equipment will be delivered from Trondheim, Norway, with commissioning in New York during July 2013.

The ferry ride offers iconic views of the New York skyline.

Siemens has signed a contract for large energy storage systems (ESS) for four of Scandlines’ current ferries. Each system consists of a Shipnet Supply that delivers up to 3 MW charge and discharge power. The energy is stored in 2.6 MWh energy storage modules realized by lithium batteries. The battery modules are delivered in partnership with Corvus Energy.

The new system will be integrated into the existing 6.6 kV switchboard. It charges excess energy from the power station to achieve energy production from thegenerator sets at the lowest possible fuel consumption per kilowatt hour. During manoeuvres, all engines but one are stopped and the BlueDrive ESS system works as an artificial generator to feed the stored energy back into the electric-propulsion system. Scandlines has calculated fuel savings at 15 to 20%. In addition,

generator-set maintenance cost reductions are expected from optimized running and improved utilization of each generator set. Due to the energy storage modules’ capacity and flexibility, an existing generator set will be removed.

This new contract strengthens the positionof Siemens BlueDrive as the most innovativeand flexible propulsion system on the market.

Scandlines was founded in 1998 and is one of Europe's largest ferry operators. Vessels operate on short routes between Denmark, Germany and Sweden.

Shipbuilding is facing the same challenges as other industries. Networks are rapidly changing, with more design outsourcing, cross-enterprise engineering, contractmanufacture and life-time support contracts. The shipyard and entire supply chain has to manage the complexity of communication in a heterogeneous environment.

Ships are traditionally designed using many different design and engineering applications. Drawings and models are constructed using different systems, which makes exchange of product information troublesome. This results in a time- consuming, costly and error-inducing system that is challenging to coordinate. Shipbuilding’s very nature is to produce one-offs or a small number of the same type of vessel. Along with the involvement of a large number of system integrators, subcontractors and suppliers this entails an enormous exchange of technical, commercial and logistical information among all parties involved. The difficultyin communication between systems of different origins represents a serious obstacle to increased competitiveness.

Ship designers see the need to take a more holistic approach to reduce the numberof systems. They want to utilize 3D right from the concept phase to enable better decision making and communication with stakeholders, reduce amendments and improve communication with shipyards.In order to do this, ship designers need technology that facilitates a top-down approach to new building processes and supports their aim for faster and better design. So far, systems have been unableto do this.

Traditional systems are specialized for ships and/or 2D applications, such as AutoCAD. These specialized solutions target a limited market, which restrictsthe amount of investment available to system development. Many software suites consist of poorly integrated programs from different suppliers that cause data flow and competence transfer problems for users.

A myriad of systems and formatsIn shipbuilding, CAD/CAE/CAM systems have been a vital part of the design and construction process for many years.Shipbuilders use different systems atdifferent design stages and for different disciplines, such as concept design, basic design, structures, analysis and outfitting. Designs are usually delivered on paper.

A new world of ship designSiemens has taken its proven solutions,

competence and experience from large

industries worldwide and applied them

to shipbuilding. these innovations

have opened the eyes of key players and

represent a new and more effective

way of developing ships.

Besides CAD/CAE/CAM, many other software tools are used for activities like production planning, project management and ERP.As a ship enters service, even more software is used for applications, such as operational performance and configuration management. But that’s not all. We haven’t yet touched on the owners, classification societies and the huge supply chain, which includes design agents, marine equipment manufacturers, other shipyards, block fabricators, system integrators and many more. Each of these organizations use their own design systems, which are often different again.

A proven platform with millions of usersSiemens PLM Software is a leading global provider of product life-cycle management (PLM) software and services with seven million licensed seats and more than 71,000 customers worldwide. Large customers in industries like automotive, aerospace and defense, and machinery and industrial equipment dictate software development to fit their business needs. The general market situation and thechallenges facing shipbuilding today are shared with these industries. They have applied Siemens’ software to turn thechallenges into competitive advantage. These proven solutions are now availableto the shipbuilding industry, including functionality specially designed for shipbuilders’ needs.

Since early 2000, Siemens PLM Software has been used by shipyards and ship designers using standard products like Tecnomatix, NX and Teamcenter. Applying this experience, NX 7.5 for ship design was launched. Teamcenter is used as the informational backbone and all functionality shipbuilders need is built into one single system. All people collaborate regardless of discipline, geography or organization, knowing thatthey are working with the same revised and correct data.

Over 150 Siemens PLM engineers are developing the ship-specific application. This autumn, Siemens PLM took shipbuildingproductivity and functionality to new levels with version NX 8.5. With this new update,the ship model is built once and then detailed and presented in accordance with the needs of different disciplines. This cuts time dramatically, mistakes are avoided and customers are able to make better decisions. Two dimensional drafts, general arrangements and reports are harvested from the master model with the knowledge

Siemens’ NX software is represented by Summit Systems in Norway.

that they’ve been generated using the right version and revision.

Siemens PLM provides a shared platform for effectively capturing, representing,organizing, retrieving and reusing product-related life-cycle information across companies. The platform allows integration of existing software, such as CAD. As this is not optimized for a shared platform, Siemens PLM Software has introduced JT technology.

Exchanging information with JTJT is an open platform for visualization, collaboration and data sharing across the product life cycle. It delivers platform and application independence, ship life-cycle support, generation of viewpoint specific images, rapid sharing of information between different regions, and protection of corporate intellectual property or company know-how over time.

JT is a mature lightweight data format that already enjoys widespread use in the automobile and aerospace industries and is equally suitable for shipbuilding. In fact, many large Asian shipbuilders have already adopted it. The success of JT and associated applications is such that JT is the preferred common data format for many large end-users and has become an ISO standard.

JT data representation is: • A rich data model with robust entity support • A high-performance, compact persistence archive format for graphical data • Best-in-class for supporting large assembly/model interactive capabilities • CAD-neutral with support for all major MCAD applications

JT data can be very lightweight, holding little more than facet data, or it can be richer and hold associations to the originalCAD information, assemblies, product structure, geometry, attributes, meta data and PMI.

Use of the JT format facilitates data exchange between all stakeholders in a shipbuilding project, for example between the shipyard, design agency and suppliers.

Saving months on a single projectThe need for remodeling in different stages and systems is eliminated with the Siemens solution. Focus is on openness, unlike traditional proprietary systems and closed technologies – the JT format is a good example of this. Another benefit providing customers with value, regardless of industry, comes when working with imported geometry from other systems. A few years ago Siemens

introduced a paradigm shift in CAD with its launch of synchronous technology in NX. Engineers can now make significant changes to imported geometry and work on models from different sources.

Taking the success to NorwayIn Norway, Siemens PLM Software is represented through Summit Systems. Summit provides the market leading software from Siemens to Norwegianindustry and provides support, training and system competence to more than350 customers. Summit first approachedthe Norwegian shipbuilding marketto gauge response. “Feedback from the shipbuilding industry has been tremendous and we already have many leading Norwegian ship designers on our customer list,” says Helge Kjeilen, Partner in Summit. “With the integrated NX and Teamcenter solution, shipbuilders finally see that they can simplify their shipdesign process and save a lot of time, while ensuring quality and accuracy.A revolution in ship design is long awaited and, now technology is strong enough, more and more shipbuilders are reaping the benefits,” concludes Kjeilen.

JT is a high-performance, compact persistence archive format for graphical data.It’s often used in the aerospace industry.
