Alliance Engineering Consultants (AEC) Case Studies and Capabilities

Gorgon Marine Loading Arm Installation Project

Client: Kellogg Joint Venture Gorgon (KJCG) / Camco Engineering Pty Ltd.

Overview AEC was engaged by KJVG via Camco to perform the full range of feasibility studies, vessel selection, detailed lift planning and detailed design of all rigging and installation aids for the installation of ten (10) Marine Loading Arms (MLA) for the Gorgon Gas Project. The Challenge The loading arms were particularly large and heavy with the LNG arms weighing 90 tonne and the Condensate arms weighing 45 tonne. Very limited installation information was available from the MLA Vendor. The Solution AEC produced a detailed 3D model of the arms and installation lift-path envelopes and identified that the standard installation procedure specified by Vendor would not work due to clashes with permanent jetty infrastructure. An alternative installation procedure was developed by AEC, thus saving the client considerable problems and down-time on site.

AEC then developed specialised lift plans, rigging design, installation aid design and jetty scaffolding layouts.

Outcome

The preliminary engineering phase of the project was executed successfully and within budget, with the Client expressing praise for AEC’s work. The detailed design phase was subsequently awarded to AEC and is currently in-progress due for completion Q1 2015.
