3 Terms and definitions
The following terms and definitions defined in GB/T 3947-1996 and GB/T 4595-2020 apply to this document:
3:1
Offshoreplatform
The general term for mobile platforms, fixed platforms, and compliant structures used for offshore oil and gas resource exploration and development:
Note 1: Rewrite GB/T 14090-2008, definition 2:2:1:
Note 2: The offshore platform is composed of superstructure, facilities and equipment, supporting structure, etc:
3:2
Airradiated noiseofoffshoreplatform
The interior and exterior of cabins such as dwelling spaces, working spaces, and machinery spaces above the water surface of the offshore platform (the cabins below the water line), due to the excitation source
Use the noise that is transmitted through the air, structure, etc:
Note: Generally, equipment including power systems, ventilation and air conditioning systems, propulsion/dynamic positioning systems, drilling systems and oil and gas production systems are connected through air and platform
The noise of the cabin radiated to the outside, the air radiated noise of outdoor equipment, the flow-induced noise caused by environmental loads such as wind, waves, and currents, and the structure of the outer wall of the cabin:
Force-response secondary external radiation noise:
3:3
Underwater radiated noise of offshore platform
The noise propagated in the water medium around the platform due to the excitation source:
Note: It mainly includes mechanical noise, hydrodynamic noise and propeller noise:
3:4
Excitationsource
Equipment and environmental loads for offshore platforms that can cause vibration or noise:
4 categories
According to the propagation medium, the radiated noise of the offshore platform is divided into the air radiated noise of the offshore platform and the underwater radiated noise of the offshore platform:
