Abstract

The invention relates to an ocean platform vibration noise comfort monitoring device and an online monitoring method. The device comprises a data storage and analysis platform which is connected witha plurality of distributed test terminals through a switch; the input end of each distributed test terminal is connected with a sensor; a computer terminal is further included and connected with the data storage and analysis platform through the switch; the distributed test terminals collect data transmitted by sensors, convert time domain signals into frequency spectrum data and transmits the frequency spectrum data to the data storage and analysis platform; the data storage and analysis platform compares the frequency spectrum data with a preset limit value and historical data, and when thefrequency spectrum data exceeds the limit value, alarm is raised. According to the invention, vibration of equipment can cabins in an ocean platform as well as air noise are monitored in real time, sothat a vibration noise abnormity fault can be eliminated timely, and it is ensured that the platform meets the comfort requirement of ship-level symbols.

Description

technical field

[0001] The invention relates to the technical field of ship vibration and noise control, in particular to an offshore platform vibration and noise comfort monitoring device and an online monitoring method. Background technique

[0002] With the continuous improvement of people's awareness of green environmental protection and the transformation of marine development methods to recycling, the impact of vibration and noise generated by offshore platforms and ships on human health and marine life is attracting increasing attention. For this reason, the International Organization for Standardization (ISO), the International Maritime Organization (IMO), the International Council for Ocean Exploration (ICES), and major classification societies all set strict requirements on the vibration of offshore platforms and the noise of cabins.

[0003] Based on the safety of offshore platforms and ship structures and the health of personnel, the International Organization fo...
