Browse LNG Development B2K Pre-FEED

Concept Engineering

Browse LNG Development B2K Pre-FEED

Benefits

Atteris delivered the pipeline shore crossing design for the 2010 B2K Reference Case Browse LNG Development. The work performed by Atteris provided Woodside with a feasible shore crossing design solution at James Price Point (JPP).

Background

For the 2010 B2K Reference Case, three deep water offshore hubs will transport gas to a Central Processing Facility (CPF) located ~300 km North West of Broome. From the CPF, product will be transported via a dry Gas Export and a Liquid Export Trunkline to an LNG processing facility at the Browse LNG Precinct near JPP on the Dampier Peninsular.

Work Performed by Atteris

Atteris performed the pre-FEED design of the Browse trunkline shore crossings. The scope of work that was delivered included:

Design Premise and Bases of Design
Geotechnical engineering model and soil testing
Feasibility studies and engineering assessments that was used as input into a multi-criteria assessment for the available shore crossing options – Open cut and trench, Horizontal Directionally Drilled (HDD), Tunnelling and Jetty
Route selection and assessment of pipeline corridors
Hazard Identification (HAZID)
Technical input and support for EPC tender scope of works
Shore crossing report
Offshore site survey and project engineering
