Export is the greatest proof of the importance and success of the Netherlands Maritime Technology (NMT). Rubber Design is since 1989 member of the NMT and in all those years we have participated in many collective trade fairs and missions. Rubber Design still takes part in the collective export activities of the NMT.
Since 1989, Rubber Design has supplied shock and vibration control solutions to all naval vessels that Damen Naval has built for the Koninklijke Marine and foreign navies.
Now Damen and Rubber Design are working together on the Combat Support Ship!
Damen Naval and Rubber Design have signed a contract for the supply of shock and vibration control solutions to protect important equipment on board the new Combat Support Ship (CSS) of the Royal Netherlands Navy (RNLN).
The vibration dampers used have two functions, namely the isolation of vibrations so that radiated underwater noise is reduced as well as reducing the shock impact as a result of an underwater explosion. In order to be able to achieve this and also to comply with the strict standards that apply on board the future generation of naval ships, Rubber Design has developed a wide range of RDS shock mountings.
Rubber Design was founded in 1979 and has grown over the years into one of the leading international specialists in solutions for the vibration, noise and shock absorption.
The company is located in Heerjansdam and has more than 100 employees
Rubber Design’s cooperation with Damen started in 1989 with the construction of the multipurpose frigates (M-frigates) of the RNLN. Since then, Rubber Design has supplied shock and vibration control solutions to all naval vessels that Damen Naval has built for the RNLN, including the amphibious transport ships HNLMS Rotterdam and HNLMS Johan de Witt, the air defence and command frigates (LCF) of the Zeven Provinciën class, the Joint Support Ship HNLMS Karel Doorman and the patrol ships of the Holland class. Jointly executed projects for foreign navies include the Diponegoro class corvettes and Martadinata class frigates for the Indonesian Navy and the Sigma Class FMMM Frigates supplied to the Royal Moroccan Navy.
Rubber Design delivers Dong Fang Hong 3
Scientific marine measurements require a minimum of underwater radiated noise. The highest
international standard for underwater noise control is the Silent-R certification, issued by DNV GL,
the Norwegian international certification body. The ‘Dong Fang Hong 3’ built by Shanghai-based
Jiangnan Shipyard (Group) Co., Ltd is the first Chinese research vessel (and the world’s fourth) to
have obtained this Silent-R certificate.
Rubber Design delivered the bespoke resilient mounting systems for ‘Dong Fang Hong 3’. Rubber
Design reached a new level in silence, based on the experience with other research vessels.
Working on more and more silence for research vessels
Rubber Design is well known with the standards and technology to minimize underwater radiated
noise from research vessels. The ICES 209 standard provides guidelines for this. Prior to the ‘Dong
Fang Hong 3’, Rubber Design already delivered mounting systems to the a few research vessels that
met this high international standard. The first one was the ‘Investigator’, operated by CSIRO, the
Commonwealth Scientific and Industrial Research Organisation. This is their state-of-the-art marine
research vessel. It supports Australia’s atmospheric, oceanographic, biological and geosciences
research from the tropical north to the Antarctic ice-edge. This vessel is equipped with MaK 9M25
engines. We achieved all of the acoustic requirements including airborne noise, vibrational
behaviour, and most importantly radiated underwater noise.

Two more silent research vessels
Rubber Design also supplied the resilient mounting system for the Norwegian fishery and
oceanographic research ship ‘Dr. Friedtjof Nansen’. It is owned by NORAD, the Norwegian Agency
for Development Cooperation, and will mainly operate in tropic and sub-tropic areas in developing
countries. This ship features MaK 9M25 and 6M20 generatorsets with a similar double-resilient
mounting design. And then there is the ‘Sir David Attenborough’ research vessel. This was built at
Cammell Laird in the UK and is now operated by BAS, the British Antarctic Survey. The vessel is
fitted with Bergen B33:45L6A and B33:45L9A engines. Rubber Design successfully provided the
resilient mounting systems for the mentioned diesel generatorsets and its exhaust equipment.
Next level: ‘Dong Fang Hong 3’
Our track record in delivering bespoke technology for noise reduction led to the ‘Dong Fang Hong 3’.
This research vessel which will be used by the Ocean University of China for a variety of
oceanographic research. Due to the nature of working in natural environments, the critical challenge
to a diesel engine is the ability to run at full power while emitting the least noise and vibration as
possible. This should be the case both within the vessel and into the marine environment. Limiting
the levels of noise and vibration pollution provides minimal disruption to marine life and to the
scientific measuring equipment on board. At Rubber Design, our experts develop solutions that
isolate the source of disturbance reducing marine noise and vibration pollution for an array of oceangoing
projects. This is a true team effort. In this case, our specialists closely worked with specialists
from Caterpillar Marine in Kiel, Germany. We joined forces to develop the unique double-resilient
mounting solution for the MaK 9M25C and 6M20C generatorsets.
Rubber Design also successfully delivered the exhaust suspension system to the shipyard. Working
from plans supplied by the shipyard, the expertise of Rubber Design meant they were able to
provide a bespoke system built precisely to design specifications.
For research vessels in general, Rubber Design is well experienced to design a suitable resilient
mounting system. Most vessels are equipped with a so-to-say double elastic mounting system.
Rubber Design provides not only the calculations for such resilient mounting system and the design
for the intermediate frame, but can serve also with measurements.

Rubber Design starts with building new test laboratory.
Rubber Design invested in a new state of the art test laboratory where the static and dynamic characteristics of new developed products can be measured and quality control of their products can be performed.
In this test laboratory two Zwick materials static testing machines till 27,5 tons, one servo hydraulic dynamic testing machine till 10 tons and one laboratory test rig for measuring the dynamic transfer stiffness are available for measuring the characteristics of all kind of products. With these machines Rubber Design has the possibility to measure the static stiffness, maximum strength, creep characteristics, dynamic characteristics, dynamic transfer stiffness and life cycle of different kind of products. The measurements can be performed with climate chambers to determine the characteristics of the products at different temperatures.
With this new test laboratory Rubber Design has the capability to measure all the characteristics of their products and guarantee a best possible quality control for all the products delivered to our customers.
Biezepol Metaalbewerking and Rubber Design will open their third branch in Heerjansdam in mid-August.
Following a nine-month architectural renovation, the building now offers endless possibilities as an office complex and a production area for the assembly of high-end parts for prop-shaft installations for mega yachts. The building will also house Rubber Design’s Propulsion Equipment division.
This new location has a surface area of roughly 4000 m², giving Rubber Design the opportunity to develop further and better anticipate the growth market in various sectors.
Rubber Design and Biezepol were extremely pleased with the opening of the second building, which is used primarily for assembly activities. However, the company grew more quickly than expected, resulting in the need for a third building. This growth was party due to the synergy between Rubber Design and Biezepol.
