Addressing a recent German Society for Maritime Technology forum in Rostock, he explained how naval architects can use flame-retardant elastic components to reduce noise and vibrations on ships and thus improve comfort in the cabins.
‘Architects and designers, and not least the owners of yachts and cruise ships, have extremely high expectations of comfort on board, yet stringent safety requirements such as fire protection must also be met,’ he remarked.
Vibration decoupling of ships flooring
In 2018, Getzner launched a flame-retardant polyurethane material for the highly effective vibration decoupling of ships flooring – Sylomer Marine.
This reduces the sound level on ships and improves comfort in cabins, plus it is IMO/SOLAS and wheelmark-certified, added Lukossek.
‘The elastic bearings are maintenance-free and, depending on the floor system, make it possible to lower the weight of typical floor constructions considerably without reducing efficiency,’ explained Lukossek.
Low static to dynamic stiffness ratio
Compared to other materials, Sylomer Marine has a very low static to dynamic stiffness ratio and is, therefore, much more acoustically effective. The measure creates a kind of box-in-box system, in which the inner hull is decoupled from the outer hull.
‘The resilient, vibration-isolating bearings reduce wear, noise and damage to the infrastructure to a minimum. Propulsion engines and wheelhouses can also be decoupled using Sylomer Marine,’ he added.
