ALTHOM

ALTHOM · Expertise

Five disciplines,
each one on its own.

Every discipline below is offered independently and can be commissioned on its own: a strength analysis without documentation, a manual to S1000D without an engineering share, a publishing chain without an editorial contract, a training course by itself. There is no package requirement and no minimum combination. Working across several of them creates advantages, but it is never a condition.

01 · Engineering

Calculation, design and verification.

Built up in Patras from 2012 under a doctorate-level aerospace engineer. The focus is load-carrying structure, metallic and composite, linear and nonlinear, static and dynamic. Over the years it extended into civil and electrical engineering.

  • ANL

    AnalyseStrength · Fatigue · Thermal · Flow

    Modelling that can be followed, assumptions that are written down, and reports in the form the applicable standard requires.

    • Structural analysis under static, dynamic, linear and nonlinear load
    • Stability analysis
    • Fatigue and damage tolerance, including crack propagation
    • Thermal analysis, transient and steady state
    • Coupled thermal and structural analysis
    • Flow analysis, profile and surface optimisation
    • Fluid–structure interaction
    • Multiphysics optimisation for weight, shape and surface
    • Stress analysis reports
  • DES

    DesignConcept · 3D · Manufacturing

    From the first concept through to a drawing a shop can work from, and on to the prototype.

    • Concept design
    • 3D design and manufacturing drawings
    • Design and calculation of metallic components
    • Design and calculation of composite components
    • Jig and tooling design
    • Structural optimisation for material use and series production
    • Prototype support through to testing
  • CIV

    Civil and structuralEurocode · AISC · GB · IS

    The same analysis methods as aerospace under a different set of rules, with documentation prepared for approval.

    • Structural verification for steel and concrete structures
    • Foundation and connection design
    • Fire protection design
    • Wind turbine structures
    • Towers and e-modules, structurally optimised
    • Cranes
    • Ship components
  • ELE

    ElectricalControl · Power · Electromagnetics

    Schematics, cabinets and control code, with the component selection and marking that has to go with them.

    • 3D design and circuit diagrams
    • Design of busbar systems
    • Control cabinet design
    • Component selection with CE marking
    • PLC and SCADA programming
    • Computational electromagnetics

02 · Technical Data & Documentation

Documentation is part of the product.

A manual that does not match the specification blocks delivery as reliably as a missing proof of strength. The technical writers at ALTHOM are engineers: they read design drawings, understand removal sequences, and write procedures that work on the actual part. Technical documentation has been part of the company since 2010.

  • DOC

    Technical writingS1000D · ATA iSpec 2200

    Not a written document but a validatable, versionable, reusable data set, from which the publication is generated.

    • Data modules
    • Business Rules Exchange (BREX)
    • Data Module Requirement List, creation and review
    • Common Information Repository implementation
  • ILL

    Technical illustration2D · 3D · Interactive

    • 2D line art, exploded and schematic views
    • 3D models and interactive representations from design data
    • Illustration to S1000D and ATA iSpec 2200
    • Preparation and conversion of legacy graphics, including CGM
  • PUB

    PublishingXML to PDF

    • Publishing to S1000D, ATA iSpec 2200 and ATA Spec 1000BR
    • Layout, style and structure optimised for reading and revision
    • Migration and conversion of legacy data into structured formats
    • Introduction of controlled language and terminology management

03 · ILS & LSA

The life of the system, in one view.

Integrated logistics support brings design, maintenance and procurement into a single consideration across the lifecycle. Used in defence, aerospace and industrial programmes. The results are prepared so they can be taken directly into S1000D and S2000M data structures.

  • LSA

    Analysis and planning

    • Logistics planning and analysis
    • Level of Repair Analysis (LORA)
    • Reliability, availability and maintainability (RAM)
    • Lifecycle cost analysis, to forecast and optimise operating cost
    • Sustainment planning for long-term maintenance strategy
  • CTL

    Control

    • Configuration management across change states and variants
    • Obsolescence management for components at end of life
    • Supply chain analysis, aimed at shortening lead times
    • Documentation and training material following the LSA result

04 · Digital & Automation

Tools built from real engineering work.

Automation at ALTHOM starts in its own workflows: where our editors get stuck on a repeating task, that task becomes a tool. A dedicated team of engineers and developers builds them. AI is used where it measurably improves the result, not for its own sake.

  • TSK

    Typical work

    • Conversion between formats, Word to XML
    • Migration between editorial systems
    • Data extraction from large bodies of PDF files
    • Automated index and list generation from XML, Word or Excel
    • Rule-based checking for completeness and specification compliance
    • Resolution of complex cross-references
    • Restructuring of XML hierarchies
    • Automation of repeating editorial and release steps
  • OWN

    Our own tools

    • ALTHOM Publisher. Publishing software for S1000D and ATA structures, released 25 February 2026
    • STE Checker. Checks technical text against ASD-STE100, marks deviations and proposes corrections
    • Checking routines that surface errors a plain XML view hides
  • HOW

    How we work

    • 1 · Analyse. Examine the existing process and measure what it actually costs
    • 2 · Prototype. Build against real data, never a constructed example
    • 3 · Integrate. Fit into the existing toolchain instead of replacing it
    • 4 · Hand over. Documentation and training, and source code where agreed, so the tool keeps running in your own environment

05 · Consulting & Training

Before the work starts, and after it lands.

Training runs in German, English or Greek, at either location or at the customer's site.

  • CON

    Consulting

    • Analysis, costing and implementation planning for documentation projects
    • Process optimisation along the existing editorial and release chain
    • Creation of Data Module Requirement Lists
    • Evaluation and selection of editorial, browser and storage systems
    • Introduction of controlled language and terminology management
    • Migration strategy for legacy data
  • TRN

    Training

    • S1000D, from decision-maker level to the editorial team
    • Simplified Technical English to ASD-STE100
    • Tool training for editorial and illustration software

  • CRT

    Certification support

Engineering recruitment, on request. Where a project needs people on site, ALTHOM places them through the affiliated company TPS (Thomas Personnel Solution) GmbH, which holds the required licence for employee leasing under the German AÜG. It is a supplementary service, not a core one, and it is provided by TPS rather than by ALTHOM GmbH.
