Although Imtech Marine is not a manufacturer, we are recognised as industry experts in understanding Heating, Ventilation and Air Conditioning technology on board any kind of ship and how it is developing. We not only deliver the special equipment required but provide the optimum HVAC design as an integral part of the energy concept for a ship. Knowhow combined with innovation is our key to success.

We have an overall knowledge of how all processes interact on board large cruise ships or navy vessels. It is simple to load a system and update or increase memory with the help of a computer, but there are improvement processes on a ship that are far more complex. Here we have to have a clear view of the future and make allowances in the planning for each vessel’s individual purpose. In addition there are regulations, economic, social

and environmental criteria that also have to be factored in, plus we know that in the ship’s life-cycle other unexpected issues often occur. Acknowledging these critical factors and possible scenarios is our strength. Designing and delivering the optimal Integrated System Solution is our ”product“.

Imtech develops the most appropriate concept for the customer’s needs and constantly tries to offer more than it is asked for, which is a genuine advantage for the owner, the shipyard, the operator and of course the other end users – the passengers and the crew. Our whole ship approach and independent design that we develop with long-established suppliers, offer competitive benefits to our customers.

Imtech Marine is one of the strongest players in the global maritime market with

a service network of more than 80 offices based along the world’s shipping routes and near major shipbuilding centres. We are specialised in Automation (Platform and Bridge), Navigation & Communication including Connectivity, Energy & Drive Systems, HVAC Solutions and Fire Protection Systems, A/V Entertainment and Maritime Information Services.

As the European market leader in full-scope HVAC solutions on board large cruise liners and navy vessels, we have a spectrum of ideas and solutions to improve the plans for new-build projects as well as conversions and life-cycle contracts. With years of experience working on HVAC systems on board German, Dutch, English, Spanish, Polish and Australian frigates, supply ships and corvettes you will find a team of dedicated experts looking forward to working with you on developing your plans.

it’s not Just a Case oF aCHieVinG 30 % saVinGs in enerGy ConsuMption.

Decades ago, before the company formerly known as Rud. Otto Meyer became Imtech Deutschland, our slogan was ”Technology for people and the environment“. For us therefore, ”Green“ was neither a new definition nor purely a political meaning. The green colour-coded scales on measurement devices used to be the general guideline for technical conformity. But values have changed with demands now for a far greater precision and awareness about the effects on environmental sustainability, economy improvements and the long-

term impact on society. Additionally, measurements are no longer limited to technical readings but are also to a degree, a reflection of your (and our) brand image and the way we are seen to be fulfilling our social responsibility. Today, more performance with less consumption is no longer a contradiction but has become a clear demand by our customers and essential in our day-to-day business. To achieve optimum efficiency and set new ”Green“ standards also brings important competitive advantages for ship owners. Being aware that the

air conditioning plant is one of the main consumers on board a ship we design and develop air conditioning systems that can operate with significant less energy. As a result, smaller and lighter engines can be used that in turn deliver on-going savings in operating costs. Furthermore, the space required for the HVAC system may also be reduced by optimising the AC-room as well as the trunk and ceiling arrangements. Depending on the system configuration a large number of ducts and pipes can be completely avoided. This means for example that for cruise ships, we can create space for more cabins – which creates more profit.

”IT’S THE COMPETITIVE BENEFITS OF OUR GREEN SHIP SOLUTIONS THAT DRIVES US.“

For years we have investigated the issue of energy consumption and efficiency in virtually every aspect. Whilst many producers have made their own components to optimise one area, we consider the whole ship approach: its performance requirements and operation times as well as its dependency on design,

infrastructure, application and climate zones. Today, larger cruise ships which offer much more comfort and performance are built. There is for example a constant demand for more entertainment media or some even have huge glass exterior walls – yet the energy consumption needs to be decreased. Everything is taken into

account, from very simple means such as the use of LED lighting, right up to the integration of decentralised systems. These decentralised systems provide air conditioning according to the local demand in the specific area.

The ships we build are hotel complexes or leisure resorts. Except that in our case they have the built-in advantage of ocean-going mobility. Restaurants, wellness spas, leisure and sports facilities plus entertainment and shopping centres – in short, everything today’s discerning holiday-maker demands. Next to perfect service and excellent food, the one thing that determines whether passengers become”repeaters“ is the ambient comfort throughout the ship. And here, HVAC is the defining factor. Imtech has full scope knowledge of all the processes on board and has even helped to simplify their integration. Our systems today are much smaller, more powerful and more economical. They

pay for themselves more quickly and can easily be updated or upgraded. Fully customised Cabin Solutions are now a network of decentralised units that offer individual and fully automatic controls which are linked to the central system. Whether the cabin is empty or occupied and even if a balcony door is open or the bath and shower have raised the humidity level, every situation can be detected and controlled by sensors to provide maximum comfort. Changing factors such as weather, time zones, or the guests’ daily holiday programme (excursions, events etc.) can be accommodated and incorporated into the system. Another advantage is that the maintenance and service of the HVAC system can be carried

you might imagine an ATU (Air Treatment Unit) is an ATU and one AHU (Air Handling Unit) is the same as any other AHU. But this is not the case. just as each navy vessel is built for a specific purpose, so it is with certain components. Requirements can range from heavy-duty, indestructible items to those that are invisible, inaudible or even imperceptible to others. At Imtech Marine, we know from experience that total reliability, extreme robustness and 100 % performance of all components is demanded at all times and that thanks to our on-going stress tests, the shock and vibration resistance of our components have been proved. It is also taken for granted that components have to carry on functioning when the ship may well be on standby for months or when it may have been partially damaged to provide protected areas like citadels – because this could save lives.

For this reason, navy vessels in particular have extreme requirements which need special system solutions. This is our speciality. We select the best components to assemble the AHU or ATU so that it corresponds precisely to the requirements, is easy to install and maintain and is more energy efficient. We know that the optimal combination of components is key so we deliver independent product solutions across an entire range of applications and bring common-off-the-shelf products (COTS) from the civil into the naval sector.

The more accurately and reliably we can forecast the long-term costs of operation, the easier it is to make the right decisions. With large investments such as those in shipbuilding, this is certainly a more secure basis for the ship owner. Although it may not be required initially, Imtech Marine will always consider the entire life-cycle of the ship – from new builds to conversions and the final decommissioning. This also includes making an outdated ship ”greener“ and more competitive which ultimately enhances the profit. Life-Cycle Solutions at Imtech means that we really take care of everything – from global supply of

replacement parts to complete overhauls. For the ship owner this means he can accurately assess the costs for each phase in a ship’s life, which gives him a competitive advantage and also provides him with a”mobility servicing guarantee“. As a contract partner we offer one of the most extensive service networks in the world, with over 80 service stations (operating 24/7/365) and special multi-service hubs, as in Fort Lauderdale for example, where nearly every demand can be carried out immediately.

Everything we can measure, we can also improve. Innovation is what drives our R&D experts to find the best way to make your project more successful. These statements sum up the philosophy of Imtech Marine in our quest to find the optimum solution for your individual needs. Ships after all are not cars where you can use prototypes for testing purposes. That’s why we offer our customers the unique opportunity to carry out almost any type of simulation whether this may be for a complete system or just for one component detail. This of course requires a lot of experience on our part, coupled with intensive fact-finding through applied research. This gives the shipyard, the owner and the investor a host of valuable insights leading to a higher planning reliability and offering a basis for optimising their plans. Our research give details about e.g. operating procedures, energy consumption, as well as security and maintenance costs by using the methods of fluid flow simulation, dynamic system analysis and annual-cycle modelling. Those who wish

to save money by dispensing with these simulations miss out on some exceptional discoveries and valuable benefits in terms of energy savings, comfort enhancements, weight optimisation, air improvements, innovative control options and factors that increase the speed, performance and ultimately the life-span of their ship. They also miss the opportunity to explore new ideas or learn from former mistakes, which can give our customers a real competitive advantage. It is not just new build projects where we can carry out this ”problem and solution“ analysis to clearly identify costs. We can also run different simulations and concept variations on existing cruise ships to determine the payback on investment. This also extends to the training of the crew where simulation values are used to improve operating procedures which in return increases the efficiency and performance of all systems. To us the benefits of this analysis are so convincing that our experts at Imtech Marine are always available to plan and discuss this prior to making any commitment to the simulation phase.

ENERGy CONSUMPTION

TIME

01. energetic simulation Not just recently Green Ship Solutions and Energy Saving have become favourite topics of the business. After the propulsion system, the air conditioning plant is one of the main energy consumers

on board a ship. Knowing this, it is quite surprising that costly investment decisions in the field of HVAC are still determined based on rules of thumb and gut feeling. Energetic simulation and

dynamic modelling allow decision makers to perform a thorough and quantitative analysis of all interlinked elements of an air conditioning system.

03.Computational Fluid dynamics (CFd) CFD is a numerical simulation which can replicate current flow conditions that are subjected to speed, pollutant concentrations and air temperature disturbances and can verify these within any geometrical space. Even the acoustic calculations of a circuit can be represented. In shipbuilding, the CFD simulation is done by means of turbulent flow models especially in the design of the hull and the optimisation of the propeller and rudder design, or by thermal investigations covering a wide range of engine room applications. Imtech, formerly known as Rud. Otto Meyer (ROM), has been using CFD simulation for more than 20 years.
