At what wind force work stops
Absheron has plenty of windy days. Annex 2 of the Labour Code gives the limits for crane, welding and rig work in Beaufort force; here they are in metres per second.
Onshore
All crane work onshore stops at wind force 6 and above. Force 6 on the Beaufort scale is 10.8 to 13.8 m/s. Construction has lower limits: erecting a crane itself stops above force 2, installing hoists above force 3.
At sea
- Construction with crane vessels: above force 4 (above 5.5–7.9 m/s)
- Downhand welding: above force 4; vertical and overhead welding: above force 3
- Work on producing wells on fixed platforms: above force 6
- Tripping on a drilling well: above force 8 (17.2–20.7 m/s)
- All derrick work except well flushing: above force 10 (24.5–28.4 m/s)
Heat and cold
Above 41 °C, work stops outdoors and in buildings without cooling. At minus 10 °C or colder with wind above force 3, outdoor work stops or warming breaks are given.
The crane’s own limit
The crane maker gives its own wind limit in m/s in the load chart, and it is lower for loads with a large surface (panels, pipe bundles). We follow whichever of the two limits is lower and measure the wind with the anemometer on the boom head.
The details are as of the article’s date.
