Atteris performed the shore crossing and shallow water stabilisation design for the Wheatstone project. Key benefits realised were an environmentally sound and cost competitive shore crossing option, and a robust stability design for secondary stabilisation that facilitated efficient and reliable construction.
The Wheatstone Project is developed by Chevron and comprises the Wheatstone and Iago offshore gas fields. Production is via subsea wells and manifolds, through insulated flowlines to the Wheatstone Platform (WP). From the WP the gas and condensate is transported via a 44 inch diameter trunkline to the onshore LNG plant south of Onslow.
