Offshore noise control
Offshore platforms extract oil and gas from the seabed. The crew often works and lives offshore for weeks on end with a many machines in a small space. We ensure that they can do their jobs safely and are protected against noise nuisance.
Offshore platform focal points
Platforms must comply with the established noise requirements set, for example, by NORSOK.
These are the focal points related to noise standards for offshore platforms:
Generators provide offshore power supplies. The sets produce quite a few decibels. We fit acoustic enclosures to the sets. They are fully customised, in accordance with the applicable offshore guidelines and requirements. We also take care of their installation, which is carried out by our experienced, offshore certified technicians.
A one-person crane cabin, or soundproof cabins in an engine room… Customisation allows Alara-Lukagro to provide a solution for any noise issue.
Minimise health risks posed by toxic gases and oil vapours, through effective extraction for shakers. Alara-Lukagro designs a ventilation system including silencers so that noise does not escape outside through the outlet openings.
Engines, pumps, compressors, etc. Machines produce noise. Alara-Lukagro supplies diverse solutions for this issue: soundproof cabins so that employees can control the machines from a quiet room, or acoustic enclosures fitted around the equipment.
Mobile containers used as a gym, smoking room or recreation room. Alara-Lukagro has designed many of these and supplied them as complete products for diverse platforms. Naturally, in accordance with all applicable offshore regulations and requirements.
Kitchen, accommodation, pit rooms etc. All quarters must be ventilated. Alara-Lukagro reduces noise from the ventilation openings using silencers and hoods in or on the ventilation openings. As a result many platforms comply once more with the established noise requirements.
An offshore platform 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 during renovation work. Alara-Lukagro takes care of this for you, with in-house blasting, wet paint and powder-coating facilities and the possibility of producing new doors.
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, also as an LER including electrical installations.
Enclosures and cabins
Acoustic enclosures for generator sets, pump sets, compressors and other machines and installations. Soundproof cabins for mud pump rooms, engine rooms or a complete driller’s cabin. Always designed and produced to your particular specifications, so that it is a perfect fit for your platform. Approved and certified in accordance with the latest offshore standards.
Filtered extraction system
An effective extraction system for the shakers minimises health risks for your offshore employees. Toxic gases and oil vapours that are released during this process are filtered. The air outlet is sound attenuated.
Sound attenuated air inlet and outlet
For ventilating engine rooms, pit rooms and kitchens, etc. The sound level at the air inlet and outlet is often too high. Therefore we supply complete sound attenuated air inlet and outlet sets. They are tailor-made in accordance with the latest standards, specifically for your particular offshore situation.
New offshore doors
If the existing doors are no longer adequate we can also produce new offshore doors. A30 or A60, soundproof and fire resistant. Manufactured in accordance with EC, IMO type or SOLAS regulations.
Renovation of existing doors
We examine the damage to the doors and discuss with you which doors will be renovated. We then remove the doors from the platform, renovate them at our facilities with its blast cabin, wet paint and powder-coating installation, ensure the doors comply once more with the latest applicable requirements and replace them.
