Offshore working vessels and dredging vessels
Dutch shipyards are considered all over the world to be experts in the field of maritime technology. Therefore we are incredibly proud to be a supplier to this sector! Providing high quality solutions that make your ship safer and more pleasant for those on board.
Offshore working vessels noise sources
Retaining the noise produced by the engines in the engine room: soundproof entry doors contribute to this objective. If the machines have to be controlled from this room then a soundproof control cabin offers the ideal solution.
A ship’s power supply runs day and night. We fit it with acoustic enclosures so that the noise level around the generators is acceptable.
An acoustic enclosure ensures the installation achieves the desired noise level.
An offshore working vessel has to endure a lot with the weather conditions and effects of the sea. After a number of years’ service the doors also need to be renovated or replaced. We take care of this for you, with our in-house blasting, liquid lacquer and powder-coating facilities and the possibility of producing new doors.
Rooms such as engine rooms or kitchens need ventilation openings to supply fresh air. Noise escapes through these openings. We supply silencers and hoods to be fitted on or in the ventilation ducts to achieve the established noise requirements. We also take care of all the ducting for you.
Non-standard dimensions or special design requirements? If so, we are your ideal partner. If you need non-standard containers, we can provide a suitable, customised solution. We have already supplied LER and EPU containers (including electrical installations) as well as beveling stations and smoking room containers.

Enclosures and cabins
Enclosures for generator sets, bow thrusters and other machines and installations, and soundproof cabins for engine rooms. Always designed and produced to your particular specifications, so that it is a perfect fit for your vessel. Approved and certified in accordance with the latest maritime standards. Including electrical installations, if required.
Splitter silencers or cylindrical silencers ensure that your ventilation system complies with noise requirements. They are tailor-made for you in accordance with the latest maritime standards, specifically for the particular situation on your vessel.
Sound attenuated ventilation sets
Ventilation shafts provide air supply and extraction in, for example, the engine room. Obviously, the noise produced in the engine room must not spread outside or to other rooms such as the wheelhouse. We provide your vessel with a complete, tailor-made ventilation system with, for example, cylindrical silencers, splitter silencers and fire dampers.
Do you want to equip your wall with a door? We offer high-quality soundproof doors made to your desire.
If the existing cabin doors are no longer adequate we can also produce new doors. B30 or B60, soundproof and fire resistant. Manufactured in accordance with IMO, MED, Rina, etc.
Sound barrier walls
Do you have sound sources on deck or in the machine room where you want to realise slight or directed sound attenuation? You can choose sound barrier walls as temporary or permanent solution. Depending on your project we offer a tailor-made solution. For example, think about the following possibilities:
- A range of diverse panel types, depending on the desired sound level and solidness.
- With or without steel structure.
- With desired coating.
- Possible with doors.
Working method & certificates
How do we ensure your project is a success? It all boils down to our approach, which is based on knowledge; knowledge of sound, of market demands and advanced methods such as FEM and CFD analyses. If required our solutions can also be implemented in accordance with MED, IMO, Rina, CSC, Bureau Veritas, DNV, Lloyd’s, ISO, etc.
Collaboration in the form of a partnership
“We are satisfied with Alara-Lukagro as our partner for supplying the 20 ft EPU container. I would recommend Alara-Lukagro’s services and we are looking forward to working with them again in the future.”

A surprisingly effective result
After the cabin was installed the sound level was measured by IHC Beavers Dredgers and the results were 111 dB(A) outside the cabin and 68 dB(A) in the cabin, announced as “a remarkably good result”. Since then, Alara-Lukagro has supplied another three identical soundproof cabins to IHC Merwede.
