Renovation of a Floating Floor in
the Superyacht "M.Y. Excellence"

Description of the project
Filipino firm Rouvia Road Yacht Design & Construction Corp. restored
the “M.Y Excellence” superyacht in2013 at the Freeport Area of Bataan, Philippines. Built in 1986 at theFeadship yard in the Netherlands,
the 40 m long and 8 m wide motor
yacht boasts an exceptional design and technology of the highest
standard.

The Getzner solution
The long-time behaviour of Sylomer®
coupled with previous experienceswith Getzner were reasons enoughfor Rouvia Road to award the vibration experts with the contract for fitting the floating floor with an elastic
bearing.

he challenge in this project was
to prevent vibrations and noise detracting from these features – aconsideration in both the construction and renovation of vessels of thistype.

TVibrations and secondary airborne
noise in ships are caused by the mechanical and hydrodynamic processes from engines, pumps and drive
systems. These have a detrimental
effect on the serenity and comfort
on board. To protect the "M.Y. Excellence" from undesired vibrations andto keep the noise level to a minimum,
elastic bedding of the floating floor
was carried out.
The professional vibration solution
was essential to satisfy the owner's
high demands for comfort. As a ship
is subjected to the effects of salt
water, oil and dirt, the situation iseven more challenging. The design
engineers therefore needed a highly effective and extremely durable
material.

An elastic floor bearing was used toprovide the superyacht with optimum vibration protection.
s part of the project Getzner lined approximately 60 m2 of thehull and walls with strips of Sylomer®,
isolating the inner hull from the outerhull and thereby considerably reducing vibrations and secondary airborne noise. Getzner had previously beencommissioned to supply the bearing
for the floating floor when the yacht
was originally built in 1986.

What does Rouvia Road's project
manager have to say about theproject?

As part of the nine-month restoration project, Rouvia Road removed the30-year old high-tech vibration isolating material.

"We decided to commission Getzner
due to the impressive quality of thematerial: it is highly effective and resistant, as well as easy to use. Collaborating with Getzner went reallysmoothly. Peace, quiet and comfort on board have certainly beenachieved."

Subsequent tests revealed that material characteristics, such as the static and dynamic durability, as well as
the creep behaviour, had remained
virtually the same after nearly 30 years, despite the effects of salt water,salty air, oil and dirt.
The thickness also remained unchanged, clearly highlighting the durable long-time behaviour of the material. By using Sylomer®, the first-classfeatures of the „M.Y. Excellence“
will be sustained for years to come.
"For nearly 30 years, large shipyards
around the world have been using
the high-quality Sylomer® material
for the bearing of floating floors. Thematerial is characterised by a stabletemperature response coupled withexcellent residue behaviour and very
little deflection. It is very easy tohandle and can be bonded to steel,aluminium and wood," explains Thomas Gamsjäger, the responsible project manager at Getzner.

What does the captain of the"M.Y. Excellence" have to say
about the project?
"Ever since I've been sailing thisyacht, I've been impressed with howquietly and gently she glides throughthe water. Thanks to the special bearing solution provided by Getzner,engine noise and vibrations havebeen reduced to a minimum, allowing
the qualities of the luxury yacht tocome into their own."

Durable long-time behaviourof Sylomer®
Even after nearly 30 years,
Sylomer® still displays sustained
long-time behaviour:— Virtually no changes to the material characteristics in terms ofstatic and dynamic durability as
well as the creep behaviour— Material thickness remains virtually the same
— Stable temperature response— Excellent residue behaviour— Very little deflection
Furthermore:— Easy to work with— Bonds easily with steel,— aluminium and wood
— Resistant to salt water, salty air,
oil and dirt
— Has been successfully used bylarge shipyards worldwide
