Core Capabilities

Comprehensive structural analysis across all primary offshore asset classifications — delivering rigorous verification, independent review, and long-term performance assurance for fixed platforms, floating systems, subsea infrastructure, and marine terminals. Structural analysis is the foundation of offshore asset integrity. I provide comprehensive structural verification and advisory services across the full spectrum of offshore asset classifications, ensuring that every structure is designed, analyzed, and verified against the most demanding environmental and operational conditions. Fixed Platforms: Jacket structures, gravity-based structures (GBS), and pile-supported decks. Analysis includes in-place strength, storm survival, seismic response, and foundation stability. Floating Deepwater Units: FPSOs, semi-submersibles, Tension Leg Platforms (TLP), SPAR platforms, and floating offshore wind turbines. Analysis includes global performance, mooring and riser systems, stability, and motion response. Subsea Structures: Templates, manifolds, foundation systems, and subsea connectors. Analysis includes structural integrity, fatigue, corrosion protection, installation and lifting stresses, and on-bottom stability. Marine Terminals: Jetties, berthing dolphins, loading platforms, and fendering systems. Analysis includes berthing and mooring loads, operational performance, and interface with marine systems. Analysis Capabilities: Linear and non-linear finite element analysis, dynamic response under seismic and wave loading, fatigue assessment using S-N and fracture mechanics approaches, and accidental load cases including dropped objects, blast, and fire. Compliance: All analysis is conducted in accordance with DNV, API, ISO, and NORSOK standards, with independent design verification and regulatory compliance assurance.

Compliance & Analysis

Validation Under Severe Marine Loads

Our structural advisory integrates advanced finite element modeling, dynamic fatigue calculation, seismic hazard evaluation, and complex installation stress verification. We ensure full structural integrity throughout transport, upending, jacket launching, and operational lifespan.

All structural designs conform strictly to DNV, API, ISO, and international offshore engineering codes, ensuring regulatory compliance and capital safety for multi-billion-dollar offshore assets. My offshore structural design approach is grounded in rigorous adherence to internationally recognized standards and classification society requirements. Every design is verified against the full suite of applicable codes including DNVGL-ST-0126 for offshore wind turbine support structures, DNV-OS-J101 for offshore wind turbine structures, DNV-OS-C101 for marine operations, DNV-OS-C401 for fabrication and testing, API RP 2A for fixed offshore platforms, ISO 19900 series for offshore structures, and regional regulatory requirements. Comprehensive design verification covers ultimate strength (ULS) under extreme loads including storm conditions, seismic events, and accidental loads; fatigue (FLS) analysis using damage equivalent loads and time domain simulations; accidental loads (ALS) including ship impact, dropped objects, and explosion; and serviceability (SLS) for operational performance. All designs incorporate corrosion protection systems, cathodic protection, coating systems, and materials selection to ensure long-term durability in aggressive marine environments. Fabrication and installation requirements are integrated into the design to ensure constructability and safe offshore installation. This integrated, code-compliant approach ensures the safety, reliability, and regulatory acceptance of every offshore asset — protecting both capital investment and operational integrity over the full service life. Rigorous numerical analysis is the foundation of every structural design I deliver. I utilize industry-leading finite element modeling (FEM) software including ANSYS, ABAQUS, SACs, MOSES, and Sesam for comprehensive structural verification of fixed and floating offshore structures. My numerical analysis approach includes linear and nonlinear static analysis for load-bearing capacity verification under permanent and variable loads; dynamic analysis for natural frequencies, mode shapes, and response to wave, wind, and seismic excitation; fatigue analysis in both frequency and time domains for critical connections and components; pushover analysis for ultimate strength and collapse mechanisms; time-history analysis for extreme events including earthquakes and severe storms; soil-structure interaction (SSI) modeling for foundation performance; and coupled analysis of floating systems integrating wind, wave, and current effects with mooring dynamics.

This integrated, code-compliant approach — combining rigorous numerical analysis with practical engineering judgment — ensures the safety, reliability, and regulatory acceptance of every offshore asset, protecting both capital investment and operational integrity over the full service life.
