Marine Technical Projects in Spain

When Do You Need a Naval Technical Project?

You typically require a technical project when modifications affect:

• Installed engine power or propulsion systems

• Hull, deck, or superstructure structure

• Weight distribution and vessel stability

• Change of vessel registry category (e.g., private to commercial charter)

• Administrative regularization or documentation update

What Does a Naval Technical Project Include?

A complete naval technical project usually contains:

• Technical report (Memoria Técnica) – scope and description of works

• General arrangement drawings and structural plans

• Engineering calculations (stability, structural loads, weight distribution)

• Regulatory compliance justification

• Technical certificates and inspection reports (when required)

• Photographic documentation and traceability records

The purpose is not merely administrative paperwork — it ensures structural safety, regulatory compliance, and defensible technical documentation.

The purpose of a Naval Technical Project is not merely administrative paperwork. Its objective is to ensure structural safety, regulatory compliance, and legally defensible technical documentation.

A poorly structured technical report or inconsistent engineering calculations can lead to:

• Administrative objections

• Requests for additional documentation

• Project delays

• Rejection by Maritime Authorities

For this reason, each project is prepared with:

• Clear and structured technical documentation

• Full traceability of calculations and design decisions

• Engineering justification aligned with the vessel type

• Technical coherence according to the scope of the modification

The documentation is developed in strict accordance with Spanish maritime regulations and applicable international standards, ensuring smooth processing before the Harbour Master (Capitanía Marítima) and other competent authorities.

Vessel Legalization Project

Preparation of technical documentation required to regularize a vessel before the Spanish Maritime Authorities, ensuring full compliance with safety and structural regulations.

Engine Replacement / Power Upgrade Project

An engine replacement technical project is required when an installed power or propulsion configuration changes.

The documentation includes:

• Weight distribution analysis

• Center of gravity calculation

• Structural load verification

• Stability impact assessment

• Regulatory compliance review

This ensures safe installation and successful approval by Capitanía Marítima.

Structural Modification Project

Required when modifications affect:

• Hull structure

• Deck reinforcement

• Superstructure alterations

• Structural openings or reinforcements

The project verifies that safety margins and structural integrity are maintained in accordance with naval engineering standards.

Change of Vessel Registry Category (Change of List)

When converting a vessel from private use to commercial charter (or vice versa), a technical project may be required to justify compliance with safety and operational standards.

Stability Study Project

Documentation for Spanish Maritime Authorities

A Naval Stability Study includes:

• Hydrostatic calculations

• GM and GZ curve analysis

• Intact stability verification

• Damage stability assessment (when applicable)

Mandatory when weight distribution or structural configuration changes affect transverse stability.

A properly prepared project anticipates the exact documentation required by Spanish Maritime Administration, reducing delays and avoiding administrative objections.
