Design of ships and offshore structures

Marine Engineering & Offshore Structure Design Services

The harsh ocean environment demands uncompromising structural integrity. Extreme wave slamming, corrosive saltwater, and relentless cyclic hydrodynamic loads can rapidly degrade marine vessels and offshore platforms. Designing for the maritime industry requires moving beyond static rules and employing advanced simulation-driven engineering.

At Banu Musa R&D, we provide specialized Marine Engineering and Offshore Structure Design consulting. Combining traditional naval architecture with high-fidelity computational simulation (FEA/CFD), we help shipbuilders, oil & gas operators, and renewable energy firms design, verify, and extend the operational life of their critical marine assets.

Offshore Structure Design & Verification

Whether dealing with fixed jacket platforms, semi-submersibles, or tension-leg platforms (TLPs), our engineering team conducts rigorous structural analysis to ensure compliance with DNV, ABS, and API standards.

Our offshore structure design capabilities include:

• Global Strength Analysis: Evaluating the overall structural response of offshore platforms under extreme environmental loads (wind, wave, current, and seismic activity) using advanced FEA Consultancy methodologies.

• Floating Offshore Structures & FOWT: Specialized hydrodynamic and structural design for Floating Offshore Wind Turbines (FOWT). We analyze mooring line tension, vessel seakeeping, and dynamic stability.

• Marine Fatigue & Fracture: Ocean waves cause continuous cyclic loading. We perform advanced spectral fatigue analysis to predict crack initiation and propagation in critical welded tubular joints, utilizing our dedicated Failure Analysis workflows.

Marine CFD Consulting & Hydrodynamics

Fluid dynamics define marine efficiency and safety. Traditional towing tank tests are expensive and time-consuming. As expert marine CFD consultants, we deploy numerical solvers like Ansys Fluent, Open FOAM, and Abaqus CEL to virtually simulate the ocean environment.

• Vessel Resistance & Propulsion: Optimizing hull forms (bulbous bows) to minimize wave-making and viscous drag, reducing fuel consumption and emissions. Learn more about our optimization techniques in our Design Process Optimization hub.

• Fluid-Structure Interaction (FSI): Simulating violent wave impacts, sloshing in LNG tanks, and hydrodynamic slamming on offshore structures. We map these complex transient fluid pressures directly onto structural models via our CFD Consultancy pipeline.

Lifetime Extension & Marine Failure Investigation

Aging offshore infrastructure requires critical maintenance decisions. When a marine component fails or reaches its original design life, BanuMusa R&D provides authoritative forensic engineering.

1. Fitness for Service (FFS): For offshore structures suffering from severe pitting corrosion or collision damage, we conduct Level 3 API 579 FFS Assessments to scientifically justify the continued safe operation of the asset, avoiding premature decommissioning.

2. Marine Systems Failure Analysis: From fractured propeller shafts to catastrophic engine breakdowns, we determine the root cause of the failure. Review our detailed case study on the Failure Analysis of Marine Diesel Engines to see our methodology in action.

3. Advanced Material Calibration: Accurate marine simulation requires exact material behavior under extreme cold and corrosive environments. We extract these properties through our Material Calibration services and our proprietary MatLib Database.

Frequently Asked Questions (FAQ)

What software is used for offshore structural design and analysis?

For the design of offshore structures, we utilize a combination of naval architecture tools (like Maxsurf or Moses) for hydrostatic and stability calculations, paired with SIMULIA Abaqus or Ansys Mechanical for highly detailed, non-linear structural FEA and fatigue assessment of complex joints.

How do you perform fatigue analysis on floating offshore structures?

Fatigue analysis on floating structures is typically performed using a spectral approach. We calculate the hydrodynamic loads (using diffraction/radiation theory), apply them to the structural FEA model to generate stress Transfer Functions (RAOs), and combine these with ocean wave scatter diagrams to calculate cumulative fatigue damage over the asset’s lifespan.

Can simulation predict wave slamming forces on ships?

Yes. Using advanced computational fluid dynamics (CFD) and Fluid-Structure Interaction (FSI) methods—specifically Coupled Eulerian-Lagrangian (CEL) in Abaqus or Volume of Fluid (VOF) in Ansys—we can accurately simulate violent free-surface wave slamming and predict the resulting structural deformation on the ship’s hull.
