specialist engineering
Specialist Engineering incorporates four key disciplines:
- Advanced Mechanics
- Risk and Integrity Management
- Materials and Corrosion
- Geomechanics
Peritus's capability is founded on leading industry personnel with the experience to develop innovative solutions using state of the art tools and analytical methods. Peritus capabilities include:
Advanced Mechanics
- Two and three dimensional system and component level modelling using proprietary finite element modelling programs, including ANSYS and ABAQUS
- Structural analysis using first principles with closed formed solutions and/or model testing
- Pipeline lateral and vertical (upheaval) buckling control solutions
- Pipeline walking control solutions
- Ice load development and gouge analysis and solutions
- Advanced pipeline & riser installation analysis
- Rough and/or steep seabed terrain modelling
- Seismic acceleration and displacement modelling
- Modelling of pipelines under debris flows
- Advanced solid modelling – including SURF components such as turret swivels, riser flex joints, bulk heads, buckle arrestors, J Lay collars
- Transient/Dynamic FEA of Bundled pipelines including stability, trawl gear interaction, thermal, earthquake, turbidity and debris flow interaction
- Novel testing methods and pushing the boundaries of design codes
Risk and Integrity Management
- Reliability, Availability & Maintainability (RAM) analysis
- System and equipment failure mode analysis (FMEA & FMECA) to predict the performance of new systems and components
- Execution of HAZID, HAZOP, SAFOP, ENVID reviews and management to satisfactory close out
- Quantitative risk analysis (QRA) – frequency and consequence analysis considering risk to personnel, environment and facilities
- Root Cause Analysis (RCA) to investigate incidents and find their causes to prevent reoccurrence
- SIL (safety Integrity Level) and SIF (safety instrumented function) analysis in accordance with international standards IEC 61508, IEC 61511 and ISA S84.01
- Risk-based inspection planning and management for subsea systems, pipelines, risers and mooring facilities
- Preparation of operating and maintenance manuals
- Emergency pipeline repair system evaluation, design and project Management
- Support to operators in the development and implementation of risk and integrity management systems to API 17N and ISO 20815
Materials and Corrosion
- Internal / external corrosion evaluation and control
- Materials selection
- Welding and NDE during fabrication, installation and operationst
- Fitness for Service assessments
- Fatigue and ECA assessment
- NDE of the fabrication of components and during operation Corrosion monitoring
Geomechanics
- Geophysical & Geotechnical Survey specification and management
