<strong>Lloyd</strong> <strong>Werft</strong> <strong>Bremerhaven</strong> AG<br />

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 />

We’ll put wind<br />

in your offshore<br />

sails<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 />

<strong>Bremerhaven</strong> GmbH. An experienced expert in his own right he has a<br />

particular fondness for practical issues and for customer care.<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 />

The famous trend researcher<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 />
