OPTIMIZE WIND ASSETS ACROSS THEIR ENTIRE LIFE

Structural Performance Management (SPM) connects design and operating decisions to structural behavior, helping teams reduce CAPEX and OPEX, increase production, and lower failure risk.

HIDDEN COST OF STRUCTURAL UNCERTAINTY

engineering-icon

Over-engineering

Without an accurate view of structural capacity, designs carry conservative margins. The result is heavier structures and higher CAPEX.

filter-dark

Sub-efficient production

Turbines run below their real capacity because their structural limits are unknown.

behavior-dark

Reactive maintenance

Without knowing where fatigue accumulates, maintenance follows failures instead of structural condition, and OPEX grows with it.

STRUCTURAL PERFORMANCE MANAGEMENT ACROSS YOUR WIND ASSETS

A wind turbine is under load every second it operates. Wind, waves, pitch and yaw actions, and start-up and shutdown cycles add up to millions of fatigue cycles over its life. Designs compensate with conservative margins, and operations compensate with conservative limits.

SPM builds one structural twin of the whole system that follows the asset from design through end of life, so decisions on steel, production, maintenance, and asset life are based on how the structure actually responds.

WHEN STRUCTURAL BEHAVIOR BECOMES VISIBLE

Design

Fast, parametric, high-fidelity models. Reduce conservatism and weight, and shorten design cycles from weeks to hours.

Build

Account for manufacturing tolerances and supply chain changes. Assess fabrication defects on the same parametric model and respond quickly.

Operate

Continuous stress and fatigue calculations from operating data. Reduce maintenance cost, refine operating strategy, and cut downtime.

Extend life

Calculate remaining useful life from accumulated fatigue, in line with industry standards, and extend asset life safely.

O&M cost reduction

“Enhanced technology solutions will aid in the reduction of levelized cost of energy, and support decision making by financial and insurance institutions. The partnership between ABS and Akselos will cement our position in the offshore wind market.”

TURN OPERATING DATA TO A DECISION YOU CAN DEFEND

01

Build the twin

A physics-based structural twin of your foundation, blade, or bearing. Millions of degrees of freedom, solved in seconds.

02

Connect live operations

Feed it real metocean and SCADA data. Every change in wind, waves, and load becomes updated stress, fatigue, and remaining life.

03

Decide with the margin

Design, operations, and integrity teams work from the same numbers: how much structural margin each decision uses, and what it’s worth.

WHAT SPM REVEALS IN YOUR WIND ASSETS

umaine-floater-stress

Floating Foundations

SPM shows how hull configuration and environmental loads drive fatigue and steel demand across the full structure, so teams can test thousands of design options in hours and commit to the leanest viable foundation.

  • Engineering decision: Foundation configuration, shell thickness, parametric “what if” design studies.
  • Structural response: Fatigue accumulation and stress distribution across columns, pontoons, and bracing, with 18.4M fatigue solves in 12 hours.
  • Business outcome: New design iterations in 4 minutes, 9% steel volume reduction, faster path to a bankable design.
JIP fixed jacket structure 2

Jackets

SPM shows how design choices affect fatigue, stiffness, and steel demand across the full jacket in one integrated model, so teams can test thousands of scenarios in minutes and design lighter without added risk.

  • Engineering decision: Jacket design alternatives, pile design, in-place, collapse, and pre-service load cases.
  • Structural response: Fatigue damage factor reduced by 5 to 10, natural frequencies kept within OEM-specified range.
  • Business outcome: Up to 30% less steel, faster design cycles, lower fabrication cost.
wind-transition-pieces

Transition Pieces

SPM shows how geometry choices affect stress and weight across every load case, so teams can compare designs in high fidelity and keep the lightest one that passes.

  • Engineering decision: Transition piece geometry, automated parametric design sweeps.
  • Structural response: Stress distribution and capacity checked against every load case for each design variant.
  • Business outcome: 27% weight reduction, lower CAPEX, faster design workflow.

Cables

SPM shows how seabed conditions and metocean loads drive vibration and fatigue in each cable layer, so teams can target interventions where they matter instead of across the whole route.

  • Engineering decision: Free span management, what-if scenarios, live structural assessment.
  • Structural response: Vortex-induced vibration (VIV) on free spans, fatigue across individual cable layers in full 3D.
  • Business outcome: Targeted intervention, lower OPEX, fewer unplanned cable failures.

Turbine Blades

SPM shows how load cases and composite layup drive fatigue and remaining life across the blade, so teams can validate new designs faster and keep operating blades in service longer.

  • Engineering decision: New blade designs, load case evaluation, life extension on operating blades.
  • Structural response: Fatigue and risk areas across composite layers, with 600 load cases solved on a 3M DoF model in 15 seconds instead of 4+ days.
  • Business outcome: 5 additional years of blade life, faster design validation.
pitch-bearing-stress

Pitch Bearings

SPM shows how rotor loads move through the full pitch bearing assembly in one solve, so teams can derisk designs early and stay compliant with OEM methodology.

  • Engineering decision: Bearing assembly design, bolt pre-tension, OEM compliance checks.
  • Structural response: Ball-to-ring contact forces and bolt loads computed directly across hub, blade root, rings, and rolling elements.
  • Business outcome: 1,000x faster analysis, derisked design, lower failure risk.
