OFFSHORE STRUCTURAL ANALYSISBakerRisk offers a wide range of analysis capabilities for addressing structural solutions to mitigation of blast and fire threats for offshore platforms in the oil and gas industry.

Blast and Thermal LoadsBakerRisk’s Process Safety, Blast Effects, and Structures groups work closely to postulate hazardous scenarios and risks associated with operations on offshore platforms. Offshore platforms present a unique environment involving complex operations, office, recreational, living quarters, and safety equipment in a confined area. BakerRisk offers state-of-the-art computational fluid dynamics (CFD) and engineering model tools to accurately predict blast and thermal loads associated with different accident scenarios. BakerRisk can also use blast and thermal loads from third parties to calculate response of structural systems to mitigate the effects of these loads, and design upgrades, if necessary, to minimize the risk to personnel.

Structural AnalysisBakerRisk employs a wide variety of structural analysis tools to accurately predict the response of structural systems to blast and thermal loads, including Single-Degree-of-Freedom (SDOF) analysis of structural components, and sophisticated Finite Element Analysis (FEA) of complex structural systems. Offshore structural systems often involve steel frames with steel cladding where welded and bolted connections play key roles in structural integrity and survivability. Many of the software programs and methodologies employed by BakerRisk are proprietary, have been extensively validated, are fully defensible, and are accepted by the American Society of Civil Engineers (ASCE) and the American Petroleum Institute (API).

SDOF AnalysisNonlinear dynamic SDOF analysis offers quick and accurate assessment of component response to blast loads. SDOF analysis is an efficient and cost effective tool for determining problem areas in structural systems, which may need further investigation, and can also be used for upgrade design.

Thermal Analysis

Finite Element AnalysisIf refinement is necessary, or if the structural system is too complicated to be simplified to a SDOF model, BakerRisk employs FEA tools to calculate higher order response modes, structural component interactions, connection stresses, failure mechanisms, and complete structural system response.

Due to limited real estate, blast walls often become important to protect occupied spaces and critical assets from high blast loads.

Thermal AnalysisThermal loads from jet fires, pool fires, and local equipment damage can induce thermal stresses and modify physical properties of host materials, which in turn can affect structural response. Inadvertent heating can also be the root cause of failures in accident investigations. BakerRisk employs FEA tools that can couple thermal load deposition, heat transfer between different materials (fluid, gases, or solids, separated or in contact with various flow conditions), thermal stresses, and changing material properties with temperature, that can act together to accurately predict the response of critical systems.
