Introduction
In-depth interpretation of GB/T 37350—2019 Guidelines for the Design of Superstructure Structures of Jack-up Drilling Platforms
Background and purpose of the standard
GB/T 37350—2019 "Guidelines for the Design of Superstructure Structures of Jack-up Drilling Platforms" is to standardize the design of superstructure structures of jack-up drilling platforms to ensure their strength, stability and safety. This standard is proposed and managed by the National Technical Committee for Standardization of Marine Vessels and is applicable to the design of superstructure structures in the detailed design stage.
Comparison Analysis of Core Clauses
| Clause Number | Clause Content | Standard Requirements | Implementation Suggestions |
|---|---|---|---|
| 5.1.1 | The form and position of the wall shall be determined according to the general arrangement drawing for the superstructure structure. | It shall comply with the component arrangement requirements of the platform main structure. | It is recommended to conduct 3D modeling verification in the early stage of design. |
| 6.1.3 | Dimension calculation requirements for deck longitudinal girders and strong transverse beams. | The web height shall not be less than 1.6 times the opening height, and the thickness shall not be less than 4mm. | Preferably use rolled profiles to meet the section modulus requirements. |
| 6.2.15 | Requirements for stiffener connection and bracket treatment. | No bracket is provided for indoor layout, and the stiffener of the outer wall needs to be strengthened. | It is recommended to use high-web girders for local reinforcement. |
Practical application case analysis
Structural reinforcement of equipment layout area:In equipment concentrated areas, such as anchoring and mooring equipment installation platforms, special attention should be paid to the structural strength of the superstructure. It is recommended to use high-web girders or add pillars to shorten the span to ensure that the requirements of the specification are met.
