UPDATE: ABS Consulting Conducts
Comparative Risk Analyses on BP's Horn Mountain

"Using proven risk assessment tools, we conducted numerous comparative risk analyses on the unique features of Horn Mountain which were used as part of the design decision making processes"
-- Jack Vernon, ABS Consulting
s the world’s leading risk management firm, ABS Consulting was up to the
challenge when BP needed to assess various areas of risk in the design, operation and maintenance of various systems on the 13,200-ton Horn Mountain truss spar. "Using proven risk assessment tools, we conducted numerous comparative risk analyses on the unique features of Horn Mountain which were used as part of the design decision making processes" explains Jack Vernon, ABS Consulting.

Horn Mountain has the distinction of being one of the deepest dry tree production platforms in the Gulf of Mexico, and from the very beginnings of the project, preliminary design documents were reviewed from a risk management perspective. Potentially critical aspects regarding the hull integrity, marine systems were identified and addressed, thus reducing the likelihood of unforeseen issues that may arise later in the detail design stage.

"We developed models that properly represented hazards associated with the design, operation and maintenance of the different system designs and quantified these models with industry data or assumptions to generate baseline risk estimates." According to Vernon, the models created for BP’s Horn Mountain were used to compare two alternative designs for the risers, the failure probability of different riser air can designs and hard tank damage risks for different compartments.

BP's Horn Mountain field is located in Mississippi Canyon Block 127, and had first oil on 21 November 2002. Peak production is expected to be approximately 65,000 b/d of oil and 68 million cf/d of natural gas. The field is believed to hold some 150 million bbl of oil equivalent in recoverable reserves.

ABS Consulting provides a broad range of risk consulting services for hull, mooring systems, risers and topsides to assist companies in identifying, quantifying and mitigating risk as well as meeting international risk management requirements.
