Leading-edge and cost-effective

3

Anybody wanting to be successful in the marine passenger or cargo business

must be able to rely on the operational availability of their vessels – at all times.

In increasingly tough competitive environments, every hour counts. This is the

reason that the permanent availability of all of the onboard drive units has a

decisive role to play. Efficient energy management and optimized transport

capacities are also just as indispensable for cost-effective transport operations.

Competence that is convincing

All of the marine drive equipment from Siemens is fit for maritime duty – it

is extremely reliable, efficient and space-saving. This is complemented by the

fact that it is virtually maintenance-free and very user friendly. We are one

of the world’s largest and most experienced suppliers of drive technology for

ships and we provide innovative products and solutions for the complete

low-voltage and medium-voltage range. From motors and frequency converters

through converter transformers and generators up to switchgear, communi-

cation interfaces and open-loop and closed-loop control software. Our quality

products are available individually or can be integrated to create a customized

system.

Perfect interaction

When it comes to the reliability of a complete drive system, then not only

does the quality of the individual products count. Maximum availability is also

achieved as all of our components interact perfectly with one another. This

is the reason that already in the development phase we optimally match our

motors and frequency converters in our own system test facilities. This

increases the efficiency of the overall system and at the same time reduces

the operating costs.

Harmonized drive systems for all applications

Siemens has harmonized, matched system packages for all onboard drive

applications – and that for every type of ship. For instance, we can offer

the widest range of main drives, such as propeller drives for fast patrol boats

and submarines, thrust drives for self-propelled drilling platforms, booster

drives to support the ship’s diesel engine for cargo vessels or POD gondola

drives for ferries, tankers and cruise liners. Our portfolio also includes special

applications, for example, explosion-protected motors, drives for suction

and discharge pumps on dredgers, drives for bow thrusters, pumps and fans

as well as drive units for onboard compressors and various winches.

Innovation as a matter of principle

Excellent technology can always be improved further. This

is the reason that we continually develop our drive systems

– for example, by making them even more compact. The

size of our equipment is just one example. We have been

able to reduce the overall envelope dimensions of many of

our machinery series – but the power was kept the same.

Or by using space-saving IGBT power semiconductors in

our drives. We have the most compact and quietest low-

voltage drive converter in the world that has been specifically

designed for pumps, fans and compressors – on request,

also water-cooled and with degree of protection IP54.

Fit for a life at sea

Continuous vibration, heavy pitching and rolling motion

under rough sea conditions and aggressive salt-laden envi-

ronments in the machinery room – drive systems on ocean-

going vessels are subject to exceptionally tough operating

conditions. This is the reason that Siemens has developed

rugged drive solutions that are based on standard equipment.

These drives can stand up to the toughest of environmental

and ambient conditions. Special bearings and windings,

special paint finishes and additional winding insulation

protect our motors, transformers and generators from all

damaging external effects. Perfect, disturbance-free operation

is guaranteed using reinforced electrical cabinets, vibration-

proof power electronics as well as anti-condensation heating

for our frequency converters that is provided as standard.

4

Ready across the board

All of the cost-saving potential must be fully utilized where high competitive pressure

requires precise business plans. And it is precisely the ship’s technology that should

operate as efficiently as possible. This is the reason that drive solutions are demanded

which increase the performance and at the same time reduce the costs – solutions

such as those using Siemens Marine Equipment.

5

Certified on request

As a result of supplementary marine-specific qualifications

our drive systems are in full compliance with the regula-

tions of all of the common ships Classification Societies.

This means that our drive systems can be supplied with

the following certificates:

• Det Norske Veritas (DNV)

• Lloyd’s Register (LR)

• Germanischer Lloyd (GL)

• Bureau Veritas (BV)

• American Bureau of Shipping (ABS)

• Chinese Class Society (CCS)

Other ships Classification Societies

are possible on request.

Standard or special drives depending on the requirement

We develop ship-specific drive concepts for drive applica-

tions on the high seas. These concepts are based on our

standard products and drives that have been specifically

designed for marine applications. These are complemented

by completely newly developed drive solutions – for

instance our Siemens-Schottel Propulsor (SSP) and our

booster motors.

6

With high cost-saving potential:

Drives for suction-discharge pumps on dredgers

When it comes to land reclamation using dredgers, pumps

equipped with flexible drive systems are the best solution.

This is the reason why Siemens offers you variable-speed

pump applications which permit processes to be precisely

controlled. When compared to conventional technology,

this means that up to 50 % of the energy can be saved.

And not only this, the stress on the complete mechanical

drive train is reduced. Pump ratings can be as high as

several megawatts, which is why we recommend a

medium-voltage drive system as it permits especially

cost-effective operation.

Higher application flexibility: Winch drives

Winches are increasingly being equipped with three-

phase drive systems. These are more rugged and

require less maintenance than the usual hydraulic and

DC motors which are still common today. This is the

reason that these offer greater versatility in the appli-

cation. For instance, to quickly and automatically

execute position changes, their frequency converters

are equipped with control software that is specifically

tailored to the particular application. Speed and torque

are determined, depending on the particular require-

ment, via a master control system. Holding brakes and

the ratio between the braking torque and speed can

also be controlled in this fashion. The winch drive

system is directly connected to the local operator

interface, the higher-level automation system and the

emergency monitoring system through fast communi-

cation interfaces.

Reduce costs, increase profitabilityApplications and solutions

At sea, cost-effectiveness depends on different factors than for applications on

terra firma. This is the reason why we focus on making our drive systems even

more reliable, more compact and more efficient. Whether for standard products

equipped for shipboard applications or for special drives that combine electronics

from Siemens with intelligent technology to make them ideal for marine applications.

Optimum operating characteristics:

Main diesel-electric drives

Main electric drive systems rightly have the image of

being especially cost-effective, environmentally

friendly and reliable. They are admirably suited for

marine applications thanks to their excellent control,

maneuvering and positioning characteristics. They also

take up a minimum amount of space, are quiet and

have low vibration levels. Siemens generator sets not

only cover the ship’s demand but also the power require-

ments of the propeller drives – no matter whether these

involve low-voltage or medium-voltage drive systems.

However, users have even more advantages – the

installed drive power of azimuth thrusters can be flexibly

handled using variable-speed motors. This is the reason

that diesel generators can be continually operated at

the same speed and therefore are extremely energy-

saving. These drive systems are also extremely operator-

friendly – the integrated interface in the drive converter

handles the complete monitoring of the drive system

including the circuit-breaker, transformer and premag-

netizing unit. Operating personnel can separately

access all of these units so that it is easy to commission,

troubleshoot and service/maintain the system.

Can also handle even the most sophisticated of

tasks: Cargo pumps

When it comes to loading and discharging, e. g. oil or

chemical tankers, cargo pumps must handle some very

complex tasks. A continuous harmonization process is

required as a result of the quickly changing consistencies

and a flow rate which must be precisely regulated. In

this case, electric drive systems provide the best results.

Simply put, because they can quickly and precisely

respond to changing operating conditions. But also due

to their good overall efficiency, their low noise and low

pollutant emission as well as the straightforward

installation and maintenance.

Siemens can offer you a complete solution – optimally

harmonized low-voltage drive systems including the

control. This means that you can benefit from all of the

advantages of this technology without any restrictions.

By the way, we can also supply low- and medium-voltage

motors for hydraulic pumps therefore ensuring that

your complete marine system is even more compact.

Special marine drives

8

Standard marine drive systems are suitable for almost all of the typical marine

applications: From the pumps through the winches up to the main drive.

However, some special applications require dedicated solutions in order to

really achieve an optimum when it comes to energy efficiency, reliability and

transport capacity. We have a range of newly developed marine motors, which

have been newly developed from ground up for precisely these applications.

The multi-talent:

The Siemens-Schottel Propulsor (SSP)

The SSP is a POD (podded drive) – also known as gondola

drive – using permanent magnet motors. It is mounted

under the ship’s stern and can be moved as required around

its vertical axis. It is the ship’s main propulsion drive and

active control rudder at the same time: A dual function

which decisively improves the maneuverability of a ship.

It also reduces the fuel consumption with respect to

conventional diesel motors by approx. 11%. These drives

are mounted outside the ship so that they save space on

board and their power losses are directly dissipated to the

sea water. Every ship profits from an SSP – reliable, low-

maintenance with minimum noise and vibration.

High power, but compact: Booster motors

Booster drives increase, in a wide variety of ways, the main

machine power of large container ships. They support the

ship’s diesel engine when accelarating, relieve it over the

complete speed range, guarantee consistently high speeds

and improve its efficiency. The electric motor, additionally

installed on the shaft, also increases the drive power.

The booster ensures that the ship to reach its final speed

significantly faster – and in normal operation – has a lower

fuel consumption and lower maintenance costs.

Performance that moves youforward – standard marine-specificproducts

10

Reliable drives are important for every ship. The highest priority –

technical reliability and performance – for you and therefore for us.

Rugged, high-performance: Generators

When it comes to brushless synchronous generators from

Siemens, you have the choice: It doesn’t make any differ-

ence whether low- or medium-voltage synchronous

generators, with between 4 and 10 poles or in the power

range from 125 kW to 7 MW – our standard versions are

available in a wide range of configurations. In fact, for

customer-specific designs, we can even go up to power

ratings of 20 MW and more without any problem. The

voltage controllers are always included in our scope of

supply – sometimes they are even already integrated in

the generators for example, in the lower power ratings.

Our generators have an especially rugged design which

means that they are ideally suited for handling thermal

overload conditions. They are well equipped for life on

the high seas: Optimized windings and frame elements,

an offshore paint finish which is resistant to salt water,

special bearing designs which are resistant to vibration

and movement as well as anti-condensation heating and

temperature sensors for windings and bearings which

are included as standard. In the ”Marine Equipment”

version, our generators are in conformance with all of

the usual ship and offshore certificates.

11

Safe, compact, efficient:

Drive converter transformers

Siemens drive converter transformers are available in a

wide range of power ratings from 50 kW up to 25 MW.

The voltage classes range from 380 V to 11 kV.

They have a wide range of sea-going features. Our Geafol

cast-resin transformers are manufactured using a self-

extinguishing epoxy resin quartz mixture. This makes it

very difficult for them to catch fire which means that the

danger of transformer fires is basically eliminated. No

poisonous gases and vapors are emitted even when arcing

occurs. Not only this, but they are also easy to install and

generally take up less space than comparable conventional

transformers. For you this means more volume for cargo

and in turn, a higher efficiency.

This is because drive converter transformers with lower

no-load and short-circuit losses increase the efficiency,

therefore reducing the operating costs.

All of our transformers have optimized windings, which

mean that they are less prone to faults. These windings

are also mutually decoupled from one another and from

the iron core to dampen vibration. This makes them

insensitive to shock and vibration and they are as quiet

as oil-filled transformers. The foil winding principle also

ensures high AC and surge voltage strength. A special

protective paint finish, mechanical reinforcements to

suppress vibration and temperature sensors, which are

integrated in the windings, complement the extensive

range of features for duty on the high seas.

12

Reliable even under the most difficult conditions:

Motors

Siemens Marine Equipment motors combine the already

known advantages of Siemens motors with special features

that make them suitable for marine applications. Motors

above 1 kW have gray cast iron frames that can stand-up

to high stress levels, are resistant to vibration and also

dampen noise. Further, a special offshore paint system

provides a high degree of protection against corrosion in

aggressive, salty environments, extreme temperatures and

permanent moisture. Special bearing designs – e. g. high-

quality, no-play, pre-loaded, deep-groove ball bearings

or paired angular-contact ball bearings – make the motor

insensitive to vibration often encountered in marine

applications.

Especially for use on ships

Siemens Marine Equipment offers low-voltage motors

from 0.06 to 4,700 kW. For high-voltage motors, the range

even extends from 200 kW up to an incredible 50 MW. In

addition to the standard IP55 degree of protection, air-

and water-cooled motors are optionally available with

degree of protection IP56. Siemens can also offer water-

cooled low-voltage motors. Contrary to air-cooled systems,

these types of motors hardly dissipate any heat to their

environment so that they do not unnecessarily heat up

machinery rooms. These types of motors also have the

added advantage that noise levels are even lower.

13

Minimized size, maximum power: Drive converters

Siemens drive converters are also specially equipped for

marine applications. They are mechanically reinforced

and a rugged cooling system design means that heavy

rolling and pitching motion of a ship has no adverse

effects. The high standard degree of protection prevents

the ingress of water, the cabinet is tropics-proof even if

water drops in at an angle. Water-cooled drive converters

are available for tough ambient conditions. Low-voltage

drive converters for drive systems are available with

power ratings that extend from 75 kW up to 4 MW. For

pumps and fans, we can offer drive converters that are

especially quiet and compact. When compared to con-

ventional equipment they have a 30 % smaller footprint.

The degree of protection of all of the drive converters

can be increased up to IP54 without any significant

associated costs. The Active Front End (AFE) version is

available as an additional option. These self-commutated

rectifier-regenerative feedback units permit 4-quadrant

operation – not only this, sinusoidal currents with almost

no harmonics are fed back into the supply. The standard

power ratings of medium-voltage drive converters start

at about 800 kW and extend into the two-digit Megawatt

range. The innovative SIMOVERT MV is a medium-voltage

drive converter up to 7.5 MW. It is the first drive converter

of its class that is equipped with HV-IGBT power semicon-

ductors. It has some excellent features thanks to its

especially simple and modular design. SIMOVERT MV is

not only the most compact drive converter in the medium-

voltage range. It also has the maximum availability

thanks to its combination of high reliability and service-

friendliness. Large drive converters from 5 to 25 MW are

used for the main ship’s drives.
