Foreword
GB/T 30217 "Oil and gas industry drilling and oil recovery equipment" is divided into two parts.
- Part 1. Design and operation of offshore drilling riser equipment;
Part 2. Analytical methods, operations and completeness of deepwater drilling risers.
This part is part 2 of GB/T 30217.
This part is drafted in accordance with the rules given in GB/T 1.1-2009.
This part uses the translation method equivalent to ISO /T R13624-2..2009 "Oil and gas industry drilling and oil extraction equipment Part 2
. Technical Report on the Method, Operation and Integrity of Deepwater Drilling.
This part also makes the following editorial changes.
--- modified the standard name, the original name "deepwater drilling riser method, operation and integrity of technical report" changed to the part name
Called "deepwater drilling riser analysis method, operation and integrity".

3 terms and definitions
The following terms and definitions apply to this document.
3.1
Accumulator (for BOP) accumulator
A pressure vessel filled with a gas (e.g., nitrogen) in the upper part of the liquid level is used to store the hydraulic fluid under pressure to operate the BOP.
3.2
Accumulator (for riser tensioner) accumulator
The upper part of the liquid level is filled with a pressure vessel (for example, nitrogen), and the high pressure gas from the tensioner cylinder is added to the pressure vessel gas side
Pressure, the supply of high pressure hydraulic fluid to stimulate the riser tensioner cylinder.
3.3
Air buoyancy air-canbuoyancy
Top closed, bottom open air cylinder generated by the buoyancy of the buoyant force applied to the riser string, the cylinder in the water pipe outside the surrounding shape
Into an inflatable annulus.
3.4
Annoying annulus
When a tube is inside the other tube, the space between the two tubes.
3.5
Apparent weight
Effective weight
Underwater weight submergedweight
The weight of the riser in the air is reduced by the buoyancy.
