To understand the status of occupational health surveillance for workers on offshore platforms.

The research period was from 2014 to 2016. From 2014 to 2016, a cross-sectional survey method was adopted to select 429 people for offshore oil production, drilling and operation platforms and their first-line workers to conduct workplace occupational hygiene. Investigation, occupational hazard factor testing, occupational health check of workers, collation and statistical analysis of surveys and test data, and comparison of occupational health surveillance among workers of different types of offshore platforms.

From 2014 to 2016, the results of chemical harmful factors detection of occupational diseases in the offshore platform were in line with the national occupational health exposure limit requirements. The noise of some platform posts exceeded the standard, such as: oil platform oil, oil and oil and gas processing workers, diesel engines for drilling and working platforms. Worker noise exceeds national occupational health limits p[L_{ex, 8 h}>85 dB(A)].There was a statistically significant difference in the occupational health of workers on the same platform with the age and length of service (P<0.05).

Workers on different platforms at sea may be subject to different levels of occupational health damage, and the occupational hazards brought by noise to platform workers are particularly prominent.
