Subsea Decommissioning

THREE60 Subsea has completed a number of decommissioning studies for major pipelines and subsea developments.

Challenge

The challenge for operators is to effect the simplest and cheapest solution to achieve the asset decommissioning as per the agreed plans. 

Solution 

THREE60 Subsea has completed a number of decommissioning studies for major pipelines and subsea developments. In addition to the study work, THREE60 has also delivered several decommissioning projects through execution from detailed planning of the execution works, contractor selection and management, regulatory permit support, to offshore execution management and close out. Execute experience covers pipeline de-oiling, dynamic flexible riser recovery, pipeline / riser dissection and disposal, pipeline recovery as well as preparations for removal of a small southern North Sea platform – dredging, risers cuts, spool removal, pipeline end remedial works, debris clearance and environmental survey / sampling. 

Result

THREE60 has developed cost effective solutions at an early stage for input to plans / budgets as well as actual delivery of decommissioning activities offshore using our execute experience / solutions.
