Cutting Technique of Welding Groove for Intersecting of Braces at Small Angle during Liwan 3-1 CEP Jacket Fabrication

Abstract:

This paper presents the method to perform cutting of welding groove for intersecting of pipes at small angle during Liwan 3-1 CEP jacket fabrication. The mathematical model of the intersecting pipes as well as the cutting method for transition section have been studied using the principle of geometry, which enables fabrication team to print out the full scale template drawing to guide cutting of welding groove for intersecting of braces at small angle. This method has been fully tested during LW3-1 jacket fabrication which indicated that the welding groove can meet the requirements of AWS D1.1 code and the method can be adopted for future jacket construction.
