With the global emphasis on marine ecological protection, noise control on offshore drilling platforms has become a key issue in the industry's green transformation. As core noise control technologies, soundproofing enclosures and silencers significantly reduce the impact of platform operations on the marine environment by reducing noise at the source and blocking its transmission. my country's Marine Environmental Protection Law and the Action Plan for Pollution Prevention and Control during Offshore Oil and Gas Development explicitly require companies to adopt high-efficiency noise reduction technologies, and the use of soundproofing enclosures and silencers is an innovative implementation of this requirement.
1. Technical Principles and Advantages
Soundproof enclosure: creating an equipment-level "quiet cabin"
Principle: It adopts a multi-layer composite sound insulation structure (outer metal plate + middle damping layer + inner sound-absorbing material) to block the outward propagation of equipment operation noise by reflecting, absorbing and attenuating sound wave energy.
Advantages :
Modular design, adaptable to different equipment such as drilling rigs, generators, pump sets, etc.
Corrosion-resistant and salt-spray-resistant, suitable for high-humidity and high-salt environments at sea;
Integrated ventilation and cooling system ensures safe operation of the equipment.
Silencer: Precisely sniping airflow noise
Principle: For gas dynamic noise (such as exhaust ports and ventilation ducts), the energy of medium and high frequency noise is reduced through expanded anechoic cavity, porous sound absorbing materials or frequency resonance structure.
Advantages:
Small pressure loss, no impact on equipment operating efficiency;
Customizable design to match different gas flow and frequency characteristics;
It is easy to maintain and has a service life of more than 10 years.
2. Core application scenarios on offshore drilling platforms
Drilling rig power system noise reduction
Adding a fully enclosed soundproof enclosure to the diesel generator set, combined with internal sound-absorbing lining, can reduce the noise level of a single device from 110 decibels to below 85 decibels;
An impedance composite muffler is installed in the exhaust pipe to reduce high-frequency airflow noise by 30 decibels.
Noise control of pump and compressor units
A partial soundproof cover is used to cover the high-pressure pump group, focusing on isolating mechanical vibration noise;
Install a resistive muffler at the compressor air inlet to reduce the interference of low-frequency noise on platform workers.
Refined management of auxiliary equipment and pipelines
Design lightweight sound insulation enclosures for auxiliary equipment such as air-conditioning outdoor units and hydraulic stations;
The ventilation ducts use silencer elbows and silencer shutters to prevent noise from spreading along the ducts.
3. Social Benefits and Industry Value
Ecological protection: reducing the interference of underwater noise on cetacean sonar communications and maintaining marine biodiversity;
Compliance operations: Meet the requirements of national regulations such as the "Environmental Protection Standards for Offshore Oil and Gas Development" to avoid the risk of environmental penalties;
Economic benefits:
Reduce ecological compensation costs caused by noise pollution;
Extend equipment life (soundproof enclosures can reduce salt spray erosion).
