Why do we need marine and offshore insulation?

Cruise liners, passenger ships, freight ships, oil rigs and other offshore working environments need to be safe. Marine insulation helps make that possible.

For both passengers and crew located on ships and offshore platforms, securing the highest level of fire safety is crucial. A blaze could break out in a machinery space or in the process area and may have fatal consequences for those on board, or stationed there.

Choosing insulation that has been tested against the latest safety standards and approved for that application can lower this hazard, providing a safer place to work and live.

Likewise, those travelling on the sea may be exposed to loud noise levels from the elements outside, or from engines that are operating.

Ship insulation products subdue these noise levels when they are installed, making the experience of travelling a much more pleasurable experience.

Our insulation is also used to regulate temperature, by trapping heat in its stone wool fibres. This makes life on-board or offshore more comfortable and enjoyable. Plus, it can help reduce excess energy consumption – saving money for operators.

Calculator and savings

The amount of insulation needed for an application will depend on the size and type of ship or offshore construction.

For standard merchant ships like containers, which have a limited number of people on-board, the use of insulation is limited.

Commercial cruise liners meanwhile, with more than 5,000 passengers and crew on board, will require a greater amount of insulation to protect the people travelling.

Marine and offshore insulation is typically split into different applications, such as insulation for fire safety. This will also affect how much insulation will be needed for a project.

Why choose ROCKWOOL solutions?

ROCKWOOL Technical Insulation SeaRox solutions are different from other marine insulation products.

Made from stone wool, they benefit from what we call the ‘7 strengths of stone’.

These include¹:

Fire resilience – stone wool can withstand temperatures that exceed 1000°C, ensuring the highest standards of fire safety.
Thermal regulation – more heat is contained, which protects against elements outside and in, levelling temperatures in boilers, cabins and public areas².
Sound absorbing – noise from engines, propellers and other sources is subdued and reduced, making life more comfortable for workers and guests³.
Sturdy and robust – the smart fibre structure of stone wool ensures it retains its shape throughout its lifetime of use, without dropping in performance⁴.
Water properties – ROCKWOOL Technical solutions have been tried and tested for water repellence standards, achieving the lowest water absorption levels possible⁵.

Case studies

The challenge⁶

The Harmony of the Seas is one of the largest cruise ships that has ever been built. With a capacity of 5,479 guests – alongside the crew – comfort and safety for those on-board is essential. As such, the fire safety, acoustic and thermal standards of the vessel needed to be second to none.

The solution

We were chosen to be a part of this monumental project, supplying ship insulation that covered the core structure of the vessel, as well as interior cabin ceilings and walls. Overall, 1,800 tonnes of ROCKWOOL SeaRox products were installed in the Harmony of the Seas.

The results

This luxury cruise liner is now 20 percent more energy efficient than similar ships. Fire safety has also drastically improved, with non-combustible stone wool insulation raising standards. Steadier temperature levels are now possible, with the ship being protected from the sometimes bracing conditions outside.

The fire safe qualities of the insulation make the ship a safer place for crew members and guests, while the acoustic and thermal benefits create a more comfortable and relaxing environment.

Installation

General tips:

Most marine and offshore insulation is installed on steel bulkhead (walls) and deck (ceilings), fixed with pins and washers.
However, significant insulation can also be fitted in marine panels, floating floors and other technical applications.
For specific installation instructions, check the drawings for each SeaRox product. These can be found on individual product pages.

Sustainability and energy efficiency

At ROCKWOOL Technical Insulation we are committed to creating sustainable products that help our planet.

The insulation we sold in 2019 will collectively save one billion tonnes of CO² - thanks to thermal performance that regulates temperatures and reduces the need for excess heating⁷.

The stone wool we use is also created using one of the Earth’s most abundant resources: volcanic rock.

Plus, we offer a range of SeaRox Lightweight insulation solutions. By installing these lower weight insulation products, less fuel is consumed by ships – reducing carbon emissions⁸.
