How can you master the turning point in shipbuilding?
With us, quite easily. 

The ship­building industry is exposed to strong compe­ti­tion. This entails a multi­tude of chal­lenges. One answer to this is light­weight design. Making weight savings has a major impact on fuel consump­tion, as it reduces trav­el­ling resis­tance. This increases the economic effi­ciency of your fleet. More­over, this saving of resources also reduces the CO2 foot­print of each ship. This will make your customers happy. With us, you can realise the themes of light­weight design and reduc­tion of trav­el­ling resis­tance in the best possible way, because we have devel­oped inno­v­a­tive solu­tions for your chal­lenges.

  1. increasing the effi­ciency of ships in oper­a­tion
  2. cost and time pres­sure during devel­op­ment and produc­tion
  3. prob­lems with certi­fi­ca­tion

Our solu­tion compe­ten­cies

Our formula for success in inspiring solu­tions is an expe­ri­enced team that develops and opti­mises compo­nents with passion and curiosity, using the latest design and simu­la­tion tools and methods.

Solu­tion 1:
We will make your ships more effi­cient – with ease.

Inte­grating light­weight design or compos­ites in boat and ship­building creates new possi­bil­i­ties and approaches to solu­tions. We have a very good under­standing of how compo­nents or even entire assem­blies can be made lighter with the help of compos­ites. Our exten­sive exper­tise in light­weight design helps us in this. We can offer inno­v­a­tive solu­tions for ship­building in partic­ular, as we are involved in several research projects. In one of them, new tech­nolo­gies are being devel­oped to safely join fibre compos­ites with steel using new joining tech­nolo­gies. This creates new possi­bil­i­ties for weight savings. In the other research project, we are creating ways to reduce the resis­tance of hulls and thus save resources by devel­oping new hydro­foiling concepts.

This approach can make an impor­tant contri­bu­tion to making your ships more effi­cient and thus increasing their compet­i­tive­ness.

Solu­tion 2:
Save costs and time with us thanks to light­weight design.

Classic ship­building concepts reach their limits in many areas when it comes to saving on addi­tional costs, resources or time during produc­tion and oper­a­tion of the vessel. This is where inno­v­a­tive solu­tions, such as those we imple­ment in ship and boat building, can provide a remedy. We opti­mise indi­vidual compo­nents but also entire assem­blies through the use of inno­v­a­tive light­weight design concepts. As already mentioned, we are involved in research projects that enable the safe, adhe­sive- and screw-free joining of fibre compos­ites with steel compo­nents. This means that we can also enable and simplify the inte­gra­tion of composite compo­nents into existing steel assem­blies.

Our novel approaches make it possible for you to use state-of-the-art mate­rial concepts that you can easily inte­grate into your existing produc­tion flow. This saves your time, money and valu­able resources.

Solu­tion 3:
We simplify certi­fi­ca­tion of your ships.

In addi­tion to our many years of exper­tise in light­weight design and inno­v­a­tive compo­nent opti­mi­sa­tion, our in-depth knowl­edge of the boat and ship­building industry as well as our exten­sive expe­ri­ence with various clas­si­fi­ca­tion soci­eties are impor­tant success factors for the rapid certi­fi­ca­tion of your ship­building compo­nents. This makes it possible for us to provide you with holistic and targeted support in the devel­op­ment and imple­men­ta­tion of compo­nents.

Thanks to our 13 years of exper­tise, we can opti­mally manage your project and initiate the deci­sive steps in good time so that certi­fi­ca­tion is also realised within the desired time frame. This also includes docu­men­ta­tion in accor­dance with the require­ments and early tech­nical commu­ni­ca­tion with the classes.

    Lami­nate opti­mi­sa­tion for Fassmer’s hybrid boat

    In recent decades, the maritime industry has seen a rapid increase in the use of composite mate­rials due to their obvious advan­tages over metallic mate­rials. One impor­tant project was Fassmer’s PLL1600, a hybrid boat that can be used either as a tender or as a lifeboat. We were given the oppor­tu­nity to develop this water­craft in collab­o­ra­tion with Fassmer, a well-known ship­yard. One of our tasks was to opti­mise the lami­nate in order to best meet the boundary condi­tions spec­i­fied by the customer - while reducing the amount of mate­rial used.

    The following compe­tences at ar engi­neers led to success:

    • Exper­tise in struc­tural calcu­la­tions for a large number of load cases.
    • Devel­op­ment of opti­mi­sa­tion boundary condi­tions to enable produc­­tion-oriented results
    • Numer­ical opti­mi­sa­tion of the lami­nate based on simu­la­tion results from a wide range of load cases using analyt­ical methods and the Finite Element Method.
    • Gener­a­tion of lami­nate layups that meet all struc­tural and manu­fac­turing require­ments and also save resources.

    We, at ar engi­neers, were able to demon­strate our skills in the area of para­meter studies and lami­nate opti­mi­sa­tion of complex composite compo­nents in this project, which we will also use for many other indus­tries.

    Research project on the reduc­tion of hull resis­tance of vessels by means of hydro­foiling

    The aim of the research project E2MUT is to advance the devel­op­ment and market intro­duc­tion of emis­­sion-free urban mobility solu­tions on water. As a system, the project is divided into three fields of compe­tence: Mobility and Infra­struc­ture, Propul­sion Systems, and Energy Provi­sion and Elec­tric Vessels. The aim of ar engi­neers’ research in the context of this global project is the use of adap­tive or instru­men­talised CFRP foils to reduce the hull resis­tance of elec­tric vessels.

    The following compe­tences at ar engi­neers will be used and further devel­oped in the research project:

    • Concep­tual design and devel­op­ment of foil systems for hydro­foil vessels
    • CAD design of high-perfor­­mance light­weight struc­tures
    • Design, calcu­la­tion and opti­mi­sa­tion of highly stressed composite struc­tures using Ansys soft­ware
    • Devel­op­ment of an algo­rithm for the calcu­la­tion of hydro­dy­namic loads on hydro­foils using the Python program­ming language.

    At ar engi­neers, we are well placed to make a signif­i­cant contri­bu­tion to the success of this research project as we not only have many years of exper­tise in light­weight design, but we are also very expe­ri­enced in the use and further devel­op­ment of high-end soft­ware tools and methods.

    HyFiVE - researching new joining tech­nolo­gies for maritime light­weight design

    This R&D project aims to iden­tify suit­able adhe­­sive-free joining tech­nolo­gies for different appli­ca­tions in ship­building and to develop, eval­uate and adapt processes and methods to the specifics of ship­building. The contri­bu­tion of ar engi­neers to this research project is, among other things, the struc­tural eval­u­a­tion of novel joining concepts for steel-GFRP hybrids, the devel­op­ment of design and calcu­la­tion methods for the hybrid connector FAUSST as well as the opti­mi­sa­tion of the joining tech­nology from a struc­tural point of view in order to improve the mechan­ical perfor­mance in the context of a global assembly.

    The following compe­tences of ar engi­neers will be used and further devel­oped in this research project:

    • Use of simu­la­tion tools in complex projects
    • Adap­ta­tion of the Ansys simu­la­tion envi­ron­ment to special boundary condi­tions
    • Deep under­standing of the use of composite mate­rials
    • Many years of expe­ri­ence in the ship­building appli­ca­tion of composite compo­nents

    At ar engi­neers, we can make a signif­i­cant contri­bu­tion to the success of this research project, as we have exten­sive expe­ri­ence in the appli­ca­tion of light­weight design in ship­building. We are expe­ri­enced and skilled in the use of the high-end simu­la­tion tool Ansys so that we can also account for unusual boundary condi­tions in the best possible way.

    I like being part of finding solu­tions for sustain­able mobility concepts.

    The partic­i­pa­tion of ar engi­neers in the research project E2MUT (emis­­sion-free elec­tri­fied maritime urban trans­port) enables us young engi­neers to conduct research in the field of climate-neutral mobility concepts and to become part of finding solu­tions so that we will not have to do without this mobility, which is so impor­tant for all of us, and the freedom and autonomy it brings in the future.
