Technical Office™
Rigorous naval engineering for projects, technical documentation
and compliance with Class and Flag
Outsource your naval engineering with technical rigour, documental clarity and regulatory compliance.
We act as an external Technical Office for shipowners, shipyards and operators who require structural and stability calculations, 3D modelling, reliable technical documentation and projects executed in compliance with Class and Flag requirements.
Scope of services includes:
- Structural and stability calculations
- 3D modelling (Steel 3D / MARS / Rhino)
- Technical documentation for conversions, modifications and extensions
- Technical drawings and manuals
- Technical reports and justifications for Class and Flag approval.
What does Technical Office™ provide?
Clear and rigorous naval engineering, prepared for Class and Flag.
All calculations, drawings and technical documents are delivered ready for submission to Classification Societies and Flag Administrations, minimizing corrections, observations and resubmissions.
Reliable technical judgement for project decision-making.
We analyse each case and propose the safest and most viable solution, considering structural integrity, stability and operational aspects.
Agility and precision in conversions and modifications.
3D models, calculations and documentation prepared to move projects forward with technical control and operational certainty.
Flexible support adapted to the size of each shipowner.
From a single calculation to a complete conversion project, without oversized structures or rigid service packages.
Structured and traceable technical documentation.
All deliverables are provided in a professional format, with technical consistency and long-term document maintainability.
What does the service include?
Structural and stability calculations in accordance with Classification Society requirements and applicable regulations.
Naval 3D modelling (Steel 3D, MARS, Rhino).
Technical documentation for conversions, modifications and extensions.
Technical reports and justifications for Class and Flag approval.
Technical review of solutions proposed by shipyards and contractors providing independent technical support to the shipowner.
Construction drawings and updated technical manuals.
Technical feasibility analysis for projects and conversions.
Technical assistance during inspections and approval processes.
Case Study – Structural Modification with Class-ready Documentation
Project for the installation of a compact towing hook and associated structural reinforcement on a 27-metre harbour tug.
Initial situation
- Outdated drawings with limited technical traceability.
- Technical criteria not fully aligned between shipyard and shipowner.
- Risk of rejection or additional requirements from the Classification Society.
What did we implement?
At Blue Efficiency Marine™, the following technical actions were carried out:
- Detailed structural review of the affected area.
- 3D modelling of the reinforcement and associated structural calculations.
- Technical report and construction drawings prepared for submission to the Classification Society.
- Direct liaison with the Classification Society to streamline the review and approval process.
Results
- Project approved by the Classification Society.
- Reduction of the overall project schedule
- (approximately 3 weeks).
- Reduction of the final modification cost by avoiding rework and last-minute adjustments.
- Complete technical documentation, fully integrated into the PMS and the vessel’s technical file.
