Self-elevating drilling platform instrumentation process1 ScopeThis standard specifies the process preparation, process requirements, process, inspection and precautions for the jacking operation of jack-up rigs. This standard is applicable to the pile-in operation during the construction of the three-legged, pile-pushing jack-up rig, and other types of jack-up rigs Pile operations can be referred to.2 Terms and definitionsThe following terms and definitions apply to this document. 2.1 Insert spudcanpenetration When the jack-up rig is in place, the pile legs are inserted into the seabed for foundation pre-operation through the lifting system under the action of the platform's own weight and ballast water. The process of pressing and placing the legs in a stable position. Note. The pile-in-place operation generally goes through the stages of descending piles, lifting ships, piles, etc., so that the platform reaches the standing state of the predetermined air gap from the floating state. 2.2 Falling pile legdown In the floating state, the jack-up drilling platform reduces the pile legs and the pile boots to the process of contacting the pile shoes with the surface of the seabed. 2.3 Lift jackup The jack-up rig gradually lifts the platform hull to the water surface after the pile legs and pile shoes are inserted into the seabed by lowering the pile. 2.4 Pile preload After the jack-up drilling platform is lifted to the surface of the water to reach the predetermined air gap, the weight of the ballast water of the platform is gradually increased to a predetermined load, so that the pile legs The process of reaching a stable position. 2.5 Air gap airgap The clearance distance between the lower edge of the platform hull and the maximum design peak in the standing state of the jack-up rig.3 Process preparation3.1 Drawings and technical documents Before loading the jack-up rig, the following drawings and technical documents should be prepared. a) the general layout; b) the cabin map; c) draught logo and pile leg logo; d) positioning of the pile legs (pile boots); e) lifting system operation manual; f) locking system operation manual; ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 37457-2019_English be delivered?Answer: Upon your order, we will start to translate GB/T 37457-2019_English as soon as possible, and keep you informed of the progress.
