SPECIFICATIONS
Design and Construction
The offshore pipeline must be designed and constructed in accordance with Offshore Standard DNV-OS-F101 – Submarine Pipeline Systems (Offshore Pipeline), which is incorporated in its entirety in Australian Standard AS2885.4 – Pipelines, Gas and Liquid Petroleum (Part 4: Submarine Pipelines). Specifically, the design and construction phase of the pipeline must comply with
DNV-OS-F101.
Basis of Design
The pipeline design is based on the following parameters:
Item | Item Description | Details |
