Less structural noise and better comfort on board Color Line’s new hybrid ship
Color Line’s new hybrid vessel is taking shape at Ulstein Shipyard. M/S Color Hybrid will serve the Sandefjord – Strømstad route with high comfort and minimal greenhouse gas emissions.

More than just a range of superior floor screed solutions
The world's largest plug-in hybrid vessel is 160 metres long and capable of carrying 2000 passengers or about 500 cars. M/S Color Hybrid will run on batteries in and out of the Sandefjord fjord and will thus not emit greenhouses gases or nitrogen and sulfur compounds. The noise level of the vessel is low and energy recovery high. But perhaps most importantly for those who want to take a trip over the water - the ship promises a first class experience and comfort.
Reduction in structural noise
It can be difficult to avoid structural noise on board a ferry because engine and other noises reverberate through the construction. The right products can reduce this noise considerably.
«This vessel will meet stringent specification for comfort and sound insulation is a very important tool for meeting these demands. Weber products are helping us and the shipyard with this», says project director for M/S Color Hybrid, Robin Tomren at Color Line.
Weber has supplied Swedac visco elastic DG U-1, a special type of viscoelastic material for use with cement screed. This material is placed right on top of steel and reduces structural noise from the engine and generator. This makes the noise level more comfortable for passengers and the crew.
Synergy effect with GLAVA®
GLAVA® has supplied fire proof and thermal insulation that provides a weight saving of between 40 and 55 percent, compared with traditional wool insulation. This provides flexibility when it come to choosing noise reduction solutions.
"We've achieved the best possible noise reduction through a combination of components. We have chosen to use a viscoelastic layer together with steel tiles and mats of different thicknesses on M/S Color Hybrid," says department manager Elias Grønning in the project department at Fosen Ulstein Design and Engineering (FUDE).
They have designed the vessel on behalf of Fosen Yard. Although FUDE has not had any direct influence on the choice of materials, they decide what goes where and according to what values the products must be supplied.
"We give recommendations to the yard. Then it's up to the yard to choose the supplier," says Grønning. The yard chose, among others, Weber and GLAVA®.
Fibre reinforced inner decks
There aren’t many people who take the ferry from Sandefjord to Strømstad without visiting the tax-free shops and the restaurants. This means that a huge variety of goods are moved in and out, which again results in enormous stress on the inner decks of the ship. A pallet with sweets or beverages can weigh one ton, and it is moved to the pallet trailer on very small wheels.
«The inner decks on these types of ships are subject to a lot of stress, so it’s important to have high mechanical surface reinforcement on the inner decks. A fibre reinforced screed has been used on the M/S Color Hybrid. It’s called weber.floor 4660N Marine Elastic. This is a highly flexible product that can handle movements on the steel covers. Its flexibility, coupled with the fact that the screed is quick drying, means installation is quick and easy,” says Birger Erstad, Sales Manager Marine and Offshore at GLAVA® and Weber Saint-Gobain.
