Welding Requirements for Offshore Structures

This aricle focuses on welding, post-welding heat treatment (PWHT), nondestructive testing (NDT), and hardness testing requirements for the welding of offshore structures. These requirements are in addition to the guidelines outlined in API RP2A and AWS D1.1.

If the materials being used fall outside the scope of API RP2A and 01-SAMSS-018, the Consulting Services Department (CSD) will assess if additional requirements or supplementary specifications are necessary.

It is important to note that there may be additional requirements specified in Scopes of Work, Drawings, or other Instructions or Specifications that are relevant to specific work items.

When referring to the Consulting Services Department (CSD), it is understood to mean the CSD Welding Specialist or a representative designated by CSD. The term “approval” should be interpreted as written approval.

Furthermore, it is possible to attach and include this entire standard as part of purchase orders. However, it is important to note that on-deck piping should be welded in accordance with the relevant piping code and Saudi Aramco standard, as it is not covered by this particular standard.

General

The following general requirements apply:

4.1: All fabrication and inspection requirements or recommendations listed in API RP2A are considered mandatory unless otherwise specified in this standard. This means that unless stated otherwise in this particular standard, the requirements and recommendations outlined in API RP2A must be followed.

4.2: Welding details on all drawings should be presented using the AWS A2.4 “Standard Welding Symbols.” These symbols provide a standardized representation of various welding details and should be used consistently in the drawings.

4.3: Specifications and documents should utilize the AWS A3.0 “Standard Terms and Definitions” for consistent and standardized terminology in the welding context. This ensures clear communication and understanding of the specifications and documents.

4.4: These requirements apply to all sub-contractors or sub-vendors involved in the fabrication process or supplying items within the scope of this standard. This means that any external parties involved in the fabrication process or supplying relevant items must adhere to the requirements specified in this standard.

Please note that these general requirements provide an overview of the specified guidelines. For detailed and specific requirements, it is essential to refer to the complete standard document.

Low Hydrogen Electrodes to A5.1

According to the provided information, here are the requirements regarding the handling, drying, storage, and reconditioning of low hydrogen electrodes to A5.1:

Drying:

• All electrodes must be dried at a temperature between 260°C and 430°C for a minimum of 2 hours before use.
• The drying step can be skipped if the electrodes are supplied in a hermetically sealed metal can with a positive indication of seal integrity or a vacuum-sealed package.
• Electrodes can be re-dried only once.

Storage:

• After drying, the electrodes should be stored continuously in ovens at a minimum temperature of 120°C.

Exposure:

• When removing the electrodes from the drying or storage oven, hermetically sealed containers, or vacuum-sealed package, they should not be exposed to the atmosphere for more than 4 hours.
• If the electrodes are continuously stored in a portable electrode oven heated to a minimum of 65°C, the exposure time can be extended to 8 hours.
• Electrodes that have been exposed to the atmosphere for less than the permitted time period can be reconditioned.
• Electrodes that have been exposed to the atmosphere for more than the permitted time period must be re-dried.
• Wet or moist electrodes should not be used and should be discarded.

Reconditioning:

• Electrodes exposed to the atmosphere for less than the permitted time period can be returned to a holding oven maintained at a minimum temperature of 120°C.
• After a minimum holding period of four hours at 120°C, the electrodes can be reissued.

It’s important to follow these guidelines to ensure the quality and performance of low hydrogen electrodes during welding operations.

Low Hydrogen Electrodes to A5.5

According to the provided information, here are the requirements for handling, drying, storage, exposure, and reconditioning of low hydrogen electrodes to A5.5:

Drying:

• Prior to use, all electrodes should be dried at a temperature between 370°C and 430°C for a minimum of 2 hours.
• For E70xx and E80xx electrodes, the drying step can be skipped if the electrodes are supplied in a hermetically sealed metal can with a positive indication of seal integrity or a vacuum-sealed package.
• Electrodes can be re-dried only once.

Storage:

• After drying, the electrodes should be stored continuously in ovens at a minimum temperature of 120°C.

Exposure:

• Upon removal from the drying or storage oven, hermetically sealed containers, or vacuum-sealed package, the electrodes should not be exposed to the atmosphere for more than 2 hours for E70xx or E80xx electrodes and 30 minutes for higher strength electrodes.
• If the electrodes are continuously stored in a portable electrode oven heated to a minimum of 65°C, the exposure times can be doubled to 4 hours for E70xx or E80xx electrodes and 1 hour for higher strength electrodes.
• E70xx or E80xx electrodes exposed to the atmosphere for less than the permitted time period may be reconditioned.
• E70xx or E80xx electrodes exposed in excess of the permitted time period must be re-dried.
• Higher strength electrodes (above E80xx) must be re-dried after any atmospheric exposure.
• Wet or moist electrodes should not be used and should be discarded.

Reconditioning:

• After any atmospheric exposure, the electrodes must be re-dried.
• Electrodes can be re-dried only once.
• Wet or moist electrodes should not be used and should be discarded.

It is important to follow these guidelines to ensure the quality and performance of low hydrogen electrodes during welding operations, particularly to prevent hydrogen-induced cracking in the welds.
