Editorial
Welcome to OE 2013
For the next few decades, a large part of the world’s growing demand for
energy will be met by oil and gas. However, the days of easy oil and gas
are over, and more technology per barrel is required if production is to
keep pace with demand in an environmentally sound way. Therefore,
oil and gas producers around the world are focusing their attention on
technically demanding onshore reservoirs, unconventional resources, and
deep-sea fields, and looking ahead, focusing on fields in arctic regions.
This is where installing facilities is a challenge in itself.
Safety, efficiency and technical reliability are of prime importance, because
servicing offshore and especially deep-sea facilities requires a lot of effort.
Siemens provides the answers for these challenges based on its leading technological expertise in electrical engineering, power generation, transmission
and distribution, rotating equipment, automation and water treatment.
For all types of mobile units and jack-up rigs, Siemens delivers proven
solution packages that ensure reliable operation and availability – from
power supply (including fault-tolerant systems) through drives for all
applications to automation and management systems. Thanks to our
comprehensive life cycle services, our cutting-edge technologies and
our wealth of experience in furnishing offshore drilling and production
facilities, we can provide integrated design of all topside solutions as
well as the highest availability and operational efficiency for floating
production, storage and off-loading vessels (FPSOs).
For subsea applications, Siemens offers products and solutions for power,
distribution, control, processing and surveillance. Siemens also combines
a high focus on R&D and broad experience with subsea power concept
studies as well as marinization expertise in deep-sea transformers,
switchgear, variable-speed drives and subsea power control. All of these
are part of our subsea power grid solution. We began our marinization
activities more than 15 years ago, and subsea technologies have since
become an important business field that we are continually developing.
Siemens is now one of the leading suppliers of complete in-field subsea
distribution systems comprising hydraulics, electrical, and fiber-optic
components that can be supplied individually or in complete packages
as part of umbilical termination assemblies/heads. Through acquisitions
we have also significantly increased our ability to marinize our industryproven technology and accelerate our delivery of tailored solutions to
the subsea oil and gas market.

Offshore drilling:
excellent reliability on board
Innovative solution packages for
offshore drilling that secure reliable
operation and availability are in high
demand. Such solutions are exactly
what Siemens has to offer – based on
broad expertise in electrical, instrumentation and telecommunication (EIT),
rotating equipment and water treatment solutions, as well as years of
hands-on experience in the oil and
gas business and marine applications.
Siemens’ scope of supply covers the
entire life cycle of equipment and
assets, thus ensuring long-term reliability and ideal investment protection. Moreover, thanks to long-standing business partnerships with leading
shipyards, naval architects and drilling
service operators, Siemens understands the needs and demands of the
markets – and how to deliver exact solutions.
DP3 closed ring solution
Power management is of vital importance for dynamic positioning. Failures
in the power system components or
external faults should be identified
when they occur and be isolated from
the rest of the system. A system operating in DP3 mode in closed ring configuration does this, and in case of
malfunction of the primary safeguarding devices, a backup system will be put
in operation. Siemens has worked with
drilling majors and the classification
society to develop solutions operating
in DP3 mode with one fully integrated
power system.
Our solution will additionally result in
a reduction of fuel demand (about 5 %),
operating with only two engines online
and working on higher power utilization
to achieve 17 to 23 percent fewer operating hours on engines, resulting in
several advantages:
■ Lower emissions
■ Reduced contamination
of the engines
■ Diesel engines running
at a higher load level
■ Improved selectivity
in the main power system
■ Improvements for the maintenance
program of the vessel
BlueDrive drilling rig power system
For drilling jack-up rigs our new topology for the electrical system connects
the generators directly to the DC bus
via rectifier. There is no need for synchronization between generators and
it allows load sharing. This new power
solution can be combined with existing
drilling and jacking drives and various
power sources. It results in advantages
in construction, operation, and maintenance, including these effects:
■ Reduced weight
(fewer switchboards and
transformers) and size
■ Ultra-fast engine startup
■ Ultra-fast blackout prevention
and reduced recovery time
■ Lower noise for the crew
■ Reduced fuel consumption
■ Lower wear and tear
BlueDrive jacking drives
Siemens has developed an electrical
variable-speed drive jacking system
that can significantly speed up the
jacking process. Its unique diagnostic
systems give precise data feedback
during operation, which allows optimal
speed and torque control as well as
synchronization. This helps reduce the
possibility of mechanical overstress
and wear on the legs, and makes the
need for system-overrating a thing of
the past. The new Siemens BlueDrive
jacking drives thus make possible
higher efficiency, time savings, costoptimization and improved investment
protection. What is more, the new
BlueDrive jacking drives also help save
energy, as less power and less cooling
capacity are required.
BlueDrive thruster drives
Siemens has introduced an AC drive
system specially designed for propulsion applications, which ensures the
safe and reliable operation of the vessel
under all conditions. Particular effort
has been made to ensure reliable handling of both the dynamics within the
power supply system and the various
load conditions at sea. The BlueDrive
system comes with a fast-responding
blackout prevention system, and is
capable of precharging. It can, therefore, be regarded as a non-heavy consumer. Its compact converters minimize
footprint, and thereby costs, and the
system’s separate transformers ensure
the utmost flexibility in the choice of
mounting locations, thus saving up to
30 percent in space and reducing power
loss in the electrical room by as much
as 50 percent. «

between overhauls and high fuel,
flexibility with fast change rates on
gas fuel, these gas turbines are the
optimal choice for both onshore and
FPSO applications.
Gas compression
After the gas-oil separation, associated
gas can be compressed on an FPSO for
transportation onshore. Or it can be
used to fire the gas turbines and for
reinjection purposes. However, both
gas lift and gas reinjection require a
compressor to provide the appropriate
pressure. One example from Siemens’
broad lineup of field-proven electric and
mechanical drive compressors optimized
