Special vessels<br />
for New offshore challenges<br />
BILDRECHTEHINWEIS<br />
We have always built, repaired or converted ships.<br />
Very often they were expensive jobs for the specialists.<br />
But the demands placed on modern shipyards have<br />
changed and our specialisation has developed a new<br />
kind of dynamism. It has allowed us to become experts<br />
who understand offshore in the broadest sense of the<br />
word: wind power, the revitalisation of oil and gas reserves<br />
at great depths or the laying of pipes and cables<br />
on the sea bed. Highly specialised knowledge and skills<br />
are always in demand in specialised shipbuilding – and<br />
they are the expertise on which the <strong>Lloyd</strong> <strong>Werft</strong> of the<br />
future will rely. » More on Page 4<br />
The Kaiserhafen in <strong>Bremerhaven</strong> – which<br />
has been our home since 1899 – looks<br />
nothing like it did then. The offshore wind<br />
power industry has meanwhile reshaped<br />
large land and sea areas in the port. <strong>Lloyd</strong><br />
<strong>Werft</strong> <strong>Bremerhaven</strong> AG and its subsidiary<br />
company <strong>Lloyd</strong> Offshore <strong>Bremerhaven</strong><br />
GmbH are increasingly becoming an<br />
important part of this specialised shipbuilding<br />
and components industry and our<br />
prospects are long-term. We are building<br />
and repairing, providing services and acting<br />
as a reservoir of creativity for future assignments.<br />
The installation vessels “Victoria<br />
Mathias” and “Friedrich Ernestine”<br />
(photo right) are good examples of one<br />
way forward – one which is not new for us.<br />

Two big dry docks and four floating docks, more than 250,000 m 2 of yard area<br />
with efficient workshops for shipbuilding and an internationally-proven crew<br />
of specialists to master complex, innovative and creative challenges. That’s<br />
<strong>Lloyd</strong> <strong>Werft</strong> <strong>Bremerhaven</strong> AG. » More on Page 3<br />
WHAT TO DO<br />
WITH THE BALLAST WATER?<br />
The latest international IMO regulations are clear: ballast water on board<br />
has to be safe for the environment. So what is to be done? <strong>Lloyd</strong> <strong>Werft</strong> has<br />
analysed dozens of different systems and manufacturers and concluded<br />
we can do it better: tailor-made and according to ship type and size. Because<br />
we know ships. » More on Page 6<br />
GOODBYE EMISSIONS<br />
The environment does not like<br />
sulphur and nitrogen in the air.<br />
Neither do passengers on cruise<br />
liners. That’s why restrictions on<br />
emissions from ship funnels are<br />
getting ever more stringent. We<br />
have studied this problem and<br />
can deliver successful on-board<br />
know-how. » More on Page 6<br />

SAIL<br />
You have a problem on<br />
board? But you don’t want<br />
to call into a yard? That’s no<br />
problem for us. We come to<br />
you. Our teams of specialists<br />
are used to that. They<br />
also know all about engines,<br />
tanks, piping systems and<br />
about building ships. You<br />
carry on with your job at sea<br />
and we will take care of your<br />
problem. It’s called the “noworries<br />
package” from <strong>Lloyd</strong><br />
<strong>Werft</strong> and we have been<br />
making it available for many<br />
years across nearly all the<br />
seas of the world<br />
Germanischer <strong>Lloyd</strong>, Norske Veritas, <strong>Lloyd</strong>s Register, Bureau<br />
Veritas, ABS, RINA. The biggest classification societies are well<br />
known to us. Their standards are an integral part of our daily<br />
business – uncomplicated, friendly, precise and carried out by our<br />
own experienced conversion and repair experts. Because safety on<br />
board is our top priority.<br />
Ready in good Time<br />
Fred Olsen sends “Braemar” and “Balmoral” to <strong>Lloyd</strong> <strong>Werft</strong> for the first time.<br />
And “Saga Ruby” recalls the days of TV’s love boats.<br />
WILL THERE BE<br />
ANYTHING ELSE?<br />
What would you like? A ship<br />
that is longer, bigger, or<br />
more efficient? Is she too<br />
big for a new route and need<br />
shortening? Lengthening<br />
(and also shortening) of<br />
ships is one of <strong>Lloyd</strong> <strong>Werft</strong>’s<br />
globally respected specialities.<br />
At one time for example<br />
we lengthened the “Stena<br />
Hollandica” by 51.75 metres,<br />
making her the biggest RoRo<br />
passenger ship of her day in<br />
the world. We also lengthened<br />
the “Pride of America”<br />
and shortened Stena’s “Blue<br />
Putties” and “Highlander”. In<br />
record time. It’s what we do!<br />

The yard which took care of North German <strong>Lloyd</strong>’s biggest, fastest<br />
and most elegant passenger steamers in the world 100 years ago<br />
also has a special reputation to live up to today as the shipyard for<br />
the most modern cruise ships of our day. Our customers know that<br />
<strong>Lloyd</strong> <strong>Werft</strong> is simply the best when it is a question of complex repairs<br />
or, above all, conversion of cruise ships. The list of star callers<br />
is long. And it is growing all the time.<br />
Now for the first time Fred Olsen Cruise Lines have brought their<br />
two liners “Braemar” (196 m long, 24,344 GT) and “Balmoral” (217 m<br />
long, 43,537 GT ) to <strong>Lloyd</strong> <strong>Werft</strong>. In just ten and eight days respectively,<br />
we did what makes up a good part of our reputation. On the<br />
docket was a complete class certificate technical programme: dry<br />
docking, pipe-work, stabiliser overhaul, deck steelworks, painting.<br />
Extra work on “Balmoral” covered the installation of a ship catwalk,<br />
replacement of bearings on the main engine, renewal of piping,<br />
and the dismantling and re-assembly of the double rudder plant.<br />
“Saga Ruby” (191 m long, 24,492 GT) of the Saga Shipping Corp. was<br />
also in a hurry. Class work, comprehensive pipe work, pump, valve<br />
and fire-fighting plant work, steel repairs, generator replacement<br />
and tank cleaning were all carried out. The former “Caronia”, which<br />
created the TV Love Boat series as “Vistafjord” almost 40 years ago,<br />
left after three weeks, bound for England.<br />
Teamwork. This is a prerequisite for success in a shipyard which<br />
specialises in complex and demanding short-deadline performance.<br />
Even before a ship reaches <strong>Lloyd</strong> <strong>Werft</strong> the project man agers have<br />
already defined interface points with their experts, placed orders<br />
and optimised working processes. There is no little chance of there<br />
being any surprises on board. Making sure of that is the project<br />
man agement team comprising its chief Sven May, senior project<br />
manager Carl Ratjen and the head of the project department Rolf<br />
Ludemann with a team of 20 experts.<br />
More than 155<br />
YEARS EXPERIENCE<br />
When our yard was created<br />
156 years ago big passenger<br />
and cargo steamers of our<br />
own shipping company North<br />
German <strong>Lloyd</strong> (NDL) dominated<br />
the scene. Our reputation<br />
stems from this time, but<br />
above all so does our passion<br />
for and experience with<br />
ships. The legendary North<br />
German <strong>Lloyd</strong> no longer<br />
exists but our capabilities<br />
have grown out of it and been<br />
tested on countless ships on<br />
nearly all the oceans of the<br />
world. <strong>Lloyd</strong> <strong>Werft</strong> <strong>Bremerhaven</strong><br />
is a brand built on<br />
trust, capability and stability.<br />
Still being made in Germany<br />
– even after more than 155<br />
years!

Those who are satisfied with today will never experience tomorrow.<br />
The shipbuilding industry, fiercely competitive across the globe, has<br />
not only now woken up to that fact. <strong>Lloyd</strong> <strong>Werft</strong> is in a very fortunate<br />
strategic situation in the maritime centre of <strong>Bremerhaven</strong>. Located in<br />
the heart of the Überseehafen we have been at home in the historic<br />
Kaiserhafen District since 1899 on a comfortable site covering<br />
260.000 m 2 . We are well equipped with two big dry-docks, four<br />
floating docks, modern quay facilities, workshops for engineering,<br />
pipe-making, shipbuilding, a special department for aluminium and<br />
stainless steel and offices for construction planning, costing and<br />
future, is situated in a tide-free harbour and has access to two<br />
big, modern locks giving it fast access to the North Sea. We have<br />
realigned the future of our new maritime alliance group around<br />
<strong>Lloyd</strong> <strong>Werft</strong> <strong>Bremerhaven</strong> AG as a repair, conversion and new<br />
building facility, with German Dry Docks as a repair yard,<br />
<strong>Lloyd</strong> Offshore <strong>Bremerhaven</strong> GmbH as the company responsible for<br />
future wind energy business and with <strong>Lloyd</strong>s Yacht SAM. Monaco<br />
responsible for attractive niche business in mega yachts. It has<br />
always been our tradition as an innovative and professional shipyard to<br />
remain committed to the future.<br />
design. <strong>Lloyd</strong> <strong>Werft</strong> <strong>Bremerhaven</strong> AG has positioned itself well for the<br />

NETWORK<br />
BREMERHAVEN<br />
Lean. Efficient. Consistent.<br />
Professional. <strong>Lloyd</strong> <strong>Werft</strong><br />
<strong>Bremerhaven</strong> AG does not<br />
have to rely on its size. Our<br />
strength lies in our performance.<br />
And the most<br />
important part of that is a<br />
network of partner firms<br />
which has grown up on site,<br />
in the region and internationally<br />
over the decades. Not<br />
for us the burning desire to<br />
do everything ourselves. If<br />
we need support we call on<br />
the best professionals for the<br />
job in our partner network.<br />
In their company we have<br />
in the past already solved<br />
many problems, ranging<br />
from spectacular conversions<br />
through giant ship lengthening<br />
projects, completions,<br />
new buildings and demanding<br />
conversions carried out<br />
within a very short period of<br />
time. We are in favour of the<br />
division of labour, team spirit<br />
and fair play and we are open<br />
to almost everything. But our<br />
hand is always the one that is<br />
firmly on the tiller. Even as a<br />
good networker.<br />

SPECIAL VESSEL<br />
FOR NEW OFFSHORE CHALLENGES<br />
Based on a drill-ship design, the DP2-equipped CEONA AMAZON<br />
boasts exceptional sea-keeping characteristics making it ideal for<br />
operations in remote and challenging locations. Owners CEONA said<br />
the vessel was part of a fleet upgrade “to keep pace with the deepwater<br />
market”. It will carry pipe-laying equipment from HUISMAN<br />
in Holland and boast extensive under-deck storage capacity for line<br />
pipe or umbilicals as well as a deck area of 4,600m 2 for further pipe<br />
and reel storage, making it independent of costly logistics bases.<br />
Two on-board 400t mast head cranes and a single 30 t knuckle boom<br />
crane – all heave-compensated - enable heavy lift operations includ-<br />

Work has started already<br />
at <strong>Lloyd</strong> <strong>Werft</strong> <strong>Bremerhaven</strong><br />
AG on the multi-functional<br />
offshore construction<br />
vessel and pipe-laying<br />
platform CEONA AMAZON<br />
for London-based shipping<br />
company CEONA.<br />
The 33,000gt newbuilding,<br />
199.4m long, 32.2m wide<br />
and drawing 7.5m, will be<br />
part of a new generation<br />
of vessels in the CEONA<br />
fleet. The keel will be<br />
laid in August this year<br />
and she is due to enter<br />
service in late 2014.<br />
ing installation of large subsea structures singly or in tandem in<br />
water depths to 3000 metres. Two on-board work-class ROVs will be<br />
for operation down to the same depth and CEONA AMAZON will also<br />
boast a helipad and 7 thrusters.<br />
Capable of laying rigid or flexible pipelines and umbilicals, it will<br />
have accommodation for 200 personnel in 114 high standard, comfort-class<br />
cabins. The combination of pipe-laying, lifting and mobile<br />
asset flexible installation along with remote operation if required<br />
make it extremely well-suited to overall offshore field development,<br />
CEONA said.<br />
FIRST CLASS<br />
Our work is first-rate. Our<br />
customers expect outstanding<br />
performance. So it stands<br />
to reason that we take the<br />
schooling of our trainees<br />
very seriously. It is part of our<br />
future. Our backbone. It is<br />
why we built an ultra-modern<br />
training centre two years ago<br />
to school our trainees in modern<br />
technology careers in<br />
parallel with their academic<br />
training. The aim is to make<br />
them the best in their trades<br />
and to have them represent<br />
the high quality demands of<br />
<strong>Lloyd</strong> <strong>Werft</strong>. But we are not<br />
only training for ourselves<br />
in our super new workshop.<br />
Partner firms within our network<br />
are also benefiting from<br />
this special form of quality<br />
management. And that make<br />
our work even better.<br />
Exploiting wind as a source of energy now includes<br />
the sea as well as the land. And with<br />
it shipbuilding. <strong>Bremerhaven</strong> is a hub for<br />
the construction and installation of offshore<br />
wind farms. And <strong>Lloyd</strong> <strong>Werft</strong> is increasingly<br />
becoming a part of this.<br />
These two giant wind turbine installation ships are called “Friedrich<br />
Ernestine” and “Victoria Mathias”. They were built in the Republic<br />
of Korea and modified at <strong>Lloyd</strong> <strong>Werft</strong> for their work at sea. They are<br />
100 metres long, 40 metres wide and equipped with 78 metre-long<br />
jack-up legs, a loading capacity per ship of 4,500 tons, a crane which<br />
can lift 1,000 tons and towers 110 metres above deck and a DP satellite<br />
system for positioning the construction components in the sea.<br />
These two self-propelled jack-up rigs are just the beginning of a<br />
development aimed at exploiting the sea as a super power station.<br />
<strong>Lloyd</strong> <strong>Werft</strong> is part of the system and part of this development. Our<br />
experience, creativity and ability to innovate are our assets in this<br />
stormy development which is still only in its infancy.<br />
<strong>Lloyd</strong>!<br />
Quality management is the<br />
precondition for integrated,<br />
modern co-operation. That’s<br />
why certificates of yard<br />
competence in key areas are<br />
not luxuries but standard<br />
requirements. Germanischer<br />
<strong>Lloyd</strong> is responsible for these<br />
in Germany. Among others,<br />
<strong>Lloyd</strong> <strong>Werft</strong> holds ISO 14001<br />
environmental management<br />
system and ISO 9001 integrated<br />
management system<br />
certification, which is a<br />
prerequisite for international<br />
co-operation with shipping<br />
companies.<br />

<strong>Lloyd</strong> <strong>Werft</strong><br />
goes Offshore<br />
Nothing is more constant than change. And that is also true of shipbuilding. <strong>Lloyd</strong> <strong>Werft</strong>’s more than<br />
150-year old tradition is a treasure house of knowledge and experience, but we face new demands now<br />
and in the future. We talked to <strong>Lloyd</strong> <strong>Werft</strong>’s Technical Director Thorsten Beiler about what that means:<br />
When <strong>Lloyd</strong> <strong>Werft</strong> converted<br />
the drilling ship “Danwood Ice”<br />
well over 40 years ago, it was<br />
the yard’s talents in specialised<br />
shipbuilding that were mainly<br />
in demand. Since then much<br />
has happened in the offshore<br />
market, but <strong>Lloyd</strong> <strong>Werft</strong> has<br />
remained a committed and<br />
experienced specialist in all that<br />
is new and complicated. A yard<br />
that has for decades repaired,<br />
converted, lengthened as well<br />
as shortened ships and created<br />
special vessels out of run-ofthe-mill<br />
ones is ideally equipped<br />
to meet all challenges. So the<br />
offshore market is nothing new<br />
for us, but just the logical application<br />
of existing as well as<br />
new capabilities. <strong>Bremerhaven</strong><br />
has developed into one of northern<br />
Europe’s most important<br />
centres for the offshore wind<br />
power industry. <strong>Lloyd</strong> <strong>Werft</strong> is<br />
part of that, not only when it’s a<br />
question of wind power but also<br />
when special ships are needed<br />
for demanding on-board tasks in<br />
deep waters. On site experience<br />
speaks for itself and for a new<br />
chapter in the life of <strong>Lloyd</strong> <strong>Werft</strong>.<br />
Complex newbuildings and conversions to meet very challenging demands at sea are already<br />
<strong>Lloyd</strong> <strong>Werft</strong> specialities. In future however this sector – above all the booming offshore industry – will<br />
play a very special role. The newbuilding MS “Blue Giant”, delivered by <strong>Lloyd</strong> <strong>Werft</strong> in 2008 and<br />
the conversion of the “OIG Giant II” in 2011 are good examples of this. They exemplify know-how,<br />
innovation and creativity.<br />
<strong>Lloyd</strong> <strong>Werft</strong> Extra: Following the new orientation of <strong>Lloyd</strong> <strong>Werft</strong><br />
<strong>Bremerhaven</strong>, the impression is being given that the yard is developing<br />
more and more into an offshore facility. Beiler: That is only<br />
partially true. Market studies have shown that there is a high demand<br />
in the offshore sector not only for newbuildings, but also for<br />
complex and challenging conversions. For decades we have built up<br />
international experience in both. We have good project management<br />
and an experienced team of skilled people and we have not neglected<br />
our traditional strengths in newbuilding and conversion. <strong>Lloyd</strong> <strong>Werft</strong><br />
Extra: What does a challenge like this mean? Beiler: For a yard<br />
which has traditionally been at home in specialised ship building, it<br />
means, above all, adapting organisational and operational processes<br />
to the special demands of the offshore market. Everything comes in<br />
for critical scrutiny and in doing that we discover new potential for<br />
existing and future business. <strong>Lloyd</strong> <strong>Werft</strong> Extra: Can you give us an<br />
example? Beiler: Health, Security, Safety & Environment (HSSE) is<br />
typical of this and an increasingly important sector on board ship.<br />
Our audits have shown that we are already very good in this sector.<br />
Now it is a question of developing uniform standards. That makes<br />
consistent practical application on board simpler and quickly detects<br />
sources of error. Take HSSE. We already enjoy a high standard in<br />
this sector in the yard but have determined through internal and external<br />
audits that there is still potential for improvement. We have<br />
realised that consistent application not only has a positive impact<br />
on HSSE but can also lead to economic advantages for the customer<br />
and the shipyard. Our clients appreciate that. <strong>Lloyd</strong> <strong>Werft</strong> Extra:<br />
What makes <strong>Lloyd</strong> <strong>Werft</strong> so special? Beiler: Times are hard in ship<br />
building. But in the interests of our customers we have succeeded in<br />
keeping all the important trade skills required for both new building<br />
and conversion inside our own company. This makes for planning security.<br />
We complete complex tasks without interface losses, are part<br />
of a highly developed network in the whole of north Germany and<br />
have our own intelligent quality management. Above all however it is<br />
our own design department that is an important building block in our<br />
being better and faster and in remaining sustainable on the market.<br />
Thorsten Beiler (48) is a graduate engineer in<br />
shipbuilding and marine technology and is the Technical Director of <strong>Lloyd</strong><br />
<strong>Werft</strong> <strong>Bremerhaven</strong> AG. In addition he is a trained welding engineer and<br />
also the Managing Director of the new <strong>Lloyd</strong> <strong>Werft</strong> subsidiary <strong>Lloyd</strong> Offshore<br />

DP –<br />
DYNAMIC POSITIONING SYSTEM<br />
Dynamic positioning (DP) is a computer-controlled system to automatically<br />
maintain a vessel's position and heading by using its own<br />
propellers and thrusters. Position reference sensors, combined with<br />
wind sensors, motion sensors and gyro compasses, provide information<br />
to the computer pertaining to the vessel's position and the magnitude<br />
and direction of environmental forces affecting its position.<br />
The computer program contains a mathematical model of the vessel<br />
that includes information pertaining to the wind and current drag of<br />
the vessel and the location of the thrusters. This knowledge, combined<br />
with the sensor information, allows the computer to calculate<br />
the required steering angle and thruster output for each thruster.<br />
This allows operations at sea where mooring or anchoring<br />
is not feasible as deep water or congestion on the<br />
sea bottom. Dynamic positioning may either be absolute<br />
in that the position is locked to a fixed point over the bottom,<br />
or relative to a moving object like another ship or an<br />
underwater vehicle.<br />
Therefore several systems are used for referencing the position.<br />
Typical are DGPS, acoustic systems with transponders<br />
placed on the seabed and a one or more transducers placed in<br />
the ship's hull, laser beam and radar based systems.<br />
To maintain position different type of thrusters, bow thrusters,<br />
rudders and propellers are used. DP ships are usually at least<br />
partially diesel-electric, as this allows a more flexible set-up and<br />
is better able to handle the large changes in power demand, typical<br />
for DP operations. The set-up depends on the DP class of the ship.<br />
Based on an IMO publication the Classification Societies have issued<br />
rules for Dynamic Positioned Ships described as Class 1, Class 2 and<br />
Class 3 (or equivalent). In Class 1 the equipment has no redundancy.<br />
Loss of position may occur in the event of a single fault of a component<br />
or equipment. In Class 2 the layout of equipment has redundancy<br />
so that no single fault in an active system will cause the system<br />
to fail. In Class 3 passive systems have to be redundant as well and<br />
also the system to withstand fire or flood in any one compartment.<br />
The redundancy of a DP ship should be judged by a failure mode and<br />
effects analysis (FMEA) study and proved by FMEA trials. Your ship<br />
needs a DP system – ask <strong>Lloyd</strong> <strong>Werft</strong>!<br />
WAY AHEAD<br />
The future is a serious business.<br />
If customers reach the future<br />
before you do, then you will find<br />
yourself at the back of the queue.<br />

Faith Popcorn said that. We have<br />
decided to be at the front of the<br />
queue. Shaping. Creating. Being<br />
sound of judgement. Innovative.<br />
In favour of networking, fair<br />
play and the best, most reliable<br />
performance. That has been our<br />
course now for 155 years and will<br />
continue to be in the future. We<br />
have created new and future-oriented<br />
structures because markets<br />
world-wide are constantly<br />
changing. We are becoming<br />
leaner, more mobile and more<br />
attractive to our customers. Our<br />
capital is the best know-how that<br />
yards specialising in all kind of<br />
ships on a global scale can offer.<br />
Our team stands for experience,<br />
perfection, capabi lity and tempo.<br />
And if you cannot come to us in<br />
<strong>Bremerhaven</strong>, then we will come<br />
to your ship or to one of our partner<br />
yards near you.<br />
ONLY THE BEST<br />
AND THE MOST<br />
REASONABLE<br />
FOR YOU!<br />
Whether emission reduction<br />
or ballast water, we recognised<br />
the problems early and have<br />
concerned ourselves with<br />
solutions which conform to<br />
IMO regulations. We analyse<br />
plant, select the best and<br />
most suitable for you from<br />
available manufacturers<br />
and tie up the package.<br />
That’s how we see our<br />
service as a neutral<br />
adviser and advocate<br />
for our customers.<br />
One among many, but which is the one for you?<br />
BALLAST WATER CAN BECOME A COSTLY PROBLEM<br />
WE CAN SOLVE IT FOR YOU!<br />
FRESH AIR ON DECK. WET OR DRY?<br />
One thing is certain. The significant reduction in permissible levels<br />
for emissions means big challenges particularly for the operators<br />
of cruise liners. “As early as 1997 we had to concern ourselves with<br />
the cleaning of smoke gases on ships and successfully introduced<br />
catalytic emission cleaning plants”, said Rolf Ludemann (63). He is a<br />
ship engineer, served as a Chief Engineer at sea and is now the head<br />
of the project departments at <strong>Lloyd</strong> <strong>Werft</strong>. The first ships were the<br />
Ro passenger ferries “Visby”, “Thelvar” and “Birka Princess”. Since<br />
then the yard has concerned itself intensively with new processes.<br />
That’s not a problem on new buildings, but with conversions, design<br />
feasibility – stability, weight, ship structure – also have to be taken<br />
into account. Only then can the process be selected: SCR/-DeNOx<br />
plant with integrated rust filters or the removal of sulphur dioxide<br />
emissions by means of emission cleaning. In 2003 we installed such<br />
a scrubber on the “Pride of Kent”. Wet or dry de-sulphurisation?<br />
We are experienced in both processes and have, on behalf of ship<br />
owners, examined and installed the latest processes available.<br />
No ship is allowed to pump its ballast water into the sea. The IMO has laid down clear<br />
standards and regulations about this in order to protect the environment after stowaway larvae,<br />
mussels, micro-organisms and animal species, mainly from East Asia, were imported in ballast<br />
water and became a serious threat to waters in other parts of the world.<br />
LNG.<br />
THAT WORKS AS WELL<br />
LNG Liquid Natural Gas. Alternative<br />
and eco-friendly sources<br />
of energy for ship-operation are<br />
being sought, researched and<br />
decided on by the IMO across<br />
the world. Fuels like LNG,<br />
which are already well-known,<br />
are also among those under<br />
scrutiny. This is not a problem<br />
for us, but simply a question of<br />
installing special tanks on board<br />
ship, converting engine plants<br />
or installing dual-fuel engines<br />
which can run on both LNG and<br />
heavy fuel oil. Talk to us. We are<br />
already working with the people<br />
who build the engines.<br />
LESS FUEL.<br />
A COLOURFUL<br />
SOLUTION?<br />
Saving fuel on board. Not only a<br />
job for the designers of underwater<br />
hulls and bulbous bows.<br />
Germany’s Fraunhofer Institute<br />
is carrying out research into how<br />
to reduce water resistance and<br />
thus save money by using special<br />
paints on ship hulls. It’s a fascinating<br />
topic. That’s why <strong>Lloyd</strong><br />
<strong>Werft</strong> is supporting this research<br />
project. Because it is all about<br />
efficiency and saving energy and<br />
also about the environment.<br />

The treatment of ballast water is a topic which <strong>Lloyd</strong> <strong>Werft</strong> dedicated<br />
itself to some time ago. “We built a test plant for a manufacturer as<br />
early as 2006”, said mechanical engineer Stephan Bieber (28). “Up<br />
to two years ago we had collected and analysed so much information<br />
from different manufacturers that we knew which plant was<br />
most suitable for which ship”. Bieber is the expert when it comes<br />
to ballast water treatment plans on board ship. What suits the ship?<br />
This decisive question is part of the analysis. <strong>Lloyd</strong> <strong>Werft</strong> sees itself<br />
here as an adviser who makes independent recommendations and<br />
who does not do any selling, but installs the most suitable process.<br />
UV Light treatment or electrolysis. Your ship – our concept. The main<br />
criteria in this case are technical insight, economic considerations<br />
and the <strong>Lloyd</strong> <strong>Werft</strong> principle of delivering everything from a single<br />
source. “In this we are well on the way to success “, says a contented<br />
Stephan Bieber.<br />
