Structural Analysis
Evidence‑backed verification and optimisation across structures, systems, piping, and offshore operations—clear, code‑aligned, and documented for rapid stakeholder review.
From models to confident decisions
We turn your constraints into actionable engineering evidence. Using tools such as Ansys Mechanical, STAAD.Pro, CAESAR II, and Orcaflex, we validate designs, set safe operating limits, and de‑risk installations. Our approach couples global behaviour (motions, loads, RAOs) with local detail (stresses, fatigue hotspots, buckling margins) so you get the full picture for critical decisions you can sign off with confidence. Our strength lies in combining advanced analysis tools with practical, real-world engineering to achieve the best outcome for your project.
What we deliver
We support operators, OEMs, and service companies across the UKCS/North Sea, with frequent mobilisations from Aberdeen, Teesside, and Tyne & Wear—responding quickly to weather windows, TARs, and SIMOPS while keeping documents class‑ready.
Structural analysis (FEA)
Static/dynamic checks, buckling, fatigue, lifting verification, and local detail assessment.
Pipe stress analysis (CAESAR II)
ASME B31.3 code checks, supports/expansion, nozzle loads, and isometric linkage.
Hydrodynamics & sea‑keeping (Orcaflex)
RAOs, motions/accelerations, operability envelopes, and limits that drive sea‑fastening and installation plans.
Modal/harmonic & vibration
Eigenvalue and forced‑response studies to control resonance and dynamic behaviour.
Non‑linear studies
Contact, plasticity, and stability assessments in challenging geometries.
Assurance packs
Drawings, calculations, result plots, risk assessments, method statements, and O&M inputs.
Focussed on delivery
Subco delivers high‑quality engineering work, on demand. We help companies deliver critical packages of work—without the delays, overhead, or commitment of hiring. Whether it’s a capacity or capability gap, we provide defined, fixed‑price solutions that keep projects moving.
