Drilling, Completions & Intervention


DeepStar focused topics on Drilling Operations, Drilling Intervention & Repair and Plug & Abandoment where members share their experiences and data to improve deep water drilling operations. 

Flow Assurance


DeepStar topic of discussions include hydrate remediation, insulated pipelines and deepwater pigging operations with the goal to assure reliable and economic production in deepwater by the appropriate design and operation through prediction, management remediation of deposition and line plugs. 

Subsea Systems Engineering


DeepStar focus is on the advancement of Subsea equipment and installation with the responsibility for analyzing existing and/or potential technology gaps and bringing them to the attention of the committee.  A secondary focus is on the advancement of long distance tieback with the goal to develop technology and qualify equipment to enable the deployment of subsea facilities for extended mile tie-backs to ultra-deep  water depth.

Floating Systems & MetOcean


DeepStar committeess role is to further technology, develop intergrity management protocols and fill gaps related to deepwater floating systems and their associated moorings and risers. While the MetOcean's goal is to improve knowledge and modeling capabilities of the circulation flow, which will provide more accurate facility design criteria and reduce downtime during deepwater drilling operations. 

DeepStar Operations


To insure that DeepStar documents and deliverable are implemented into our members companies, the operations committee confirm that field operations and corporate actively participate within the DeepStar program.
