The Engineering Translation Challenge
Engineering firms do not tolerate ambiguity. A misplaced decimal in a tolerance specification, an unclear step in a maintenance procedure, a mistranslated material grade in a CAPEX bid — any of these can cause real damage. Tender disqualification. Warranty claims. Safety incidents. The consequences of poor translation in this sector are not hypothetical. They are documented, investigated, and sometimes litigated.
The range of documentation is broad. Technical manuals and operating instructions sit alongside tender documentation, Invitations to Tender, RFQs and RFPs. Datasheets, works instructions, QA files and HSE documentation all require the same uncompromising accuracy. A valve manufacturer needs its safety procedures rendered with the same precision in Arabic as in English. An aerospace supplier needs its quality assurance reports to read identically in Mandarin and in French.
What distinguishes engineering translation from other sectors is the bidirectional demand. English-language technical content must go outbound to international markets, certainly. But engineering firms also need foreign-language tender documents translated into English — sometimes at short notice, often under competitive pressure. Winning a contract from a French defence ministry or a German industrial group starts with understanding exactly what they are asking for. Mistranslate the requirements and the bid fails before the engineering even begins.
Engineering accounts for 4.20% of Bubbles’ revenue. The typical buyer is a Project Manager, often juggling procurement, compliance and deadline pressures simultaneously. Company size skews smaller than one might expect: 68% of our engineering clients have fewer than 200 employees. These are frequently specialist firms — world-class in their niche, operating globally, but without in-house translation capability. They need a partner who understands their terminology, their formats, and their timelines.
Since 2003, Bubbles has built that capability through sustained work with engineering clients ranging from FTSE-100 multinationals to specialist defence suppliers. The following case studies illustrate how that experience translates into practical results.
Siemens Financial Services: Earning Trust at Global Headquarters
Bubbles’ relationship with Siemens began quietly in 2009, translating technical manuals for the UK division. A decade of reliable delivery built a reputation that eventually travelled. In late 2019, Siemens’ Munich headquarters made contact with a specific problem: their financial services division needed high-quality translations across multiple languages, and years of working with various agencies had not produced satisfactory results. English-to-German quality, in particular, fell short of the standard their in-country reviewers demanded.
The solution was methodical rather than dramatic. Bubbles produced multiple sample translations in each required language, using different translators for every sample set. Siemens’ in-country review teams assessed each version and selected their preferred translator per language. This created a roster of approved translators whose style and terminology aligned precisely with each country team’s expectations.
The main project scope was quarterly marketing campaigns: website content, printed materials, whitepapers, videos, email campaigns and social media assets. The first campaign was scheduled for March 2020. Covid had other plans. Lockdowns pushed the launch to September, but the campaign calendar did not shrink — it compressed. Bubbles now needed to deliver the March, June and September campaigns by the end of September.
The approved translator model proved its worth under pressure. Because each translator already understood the client’s voice, style preferences and terminology, they could work at pace without sacrificing consistency. Translators worked evenings and weekends to clear the backlog. All three campaigns were delivered on schedule.
An ongoing feedback loop keeps the relationship sharp. In-country reviewers provide specific commentary on each deliverable, and translators adjust accordingly. This is not a complaints process — it is a calibration mechanism that tightens quality over time. Preferences that might seem subjective (tone, register, the degree of formality appropriate for a German financial audience) become codified through repetition.
The success at Munich headquarters opened further doors. Bubbles now works directly with Siemens operations in multiple countries, each engagement building on the quality framework established through that initial, painstaking translator selection process.
Didsbury Engineering: Where Precision is Not Optional
Didsbury Engineering designs and manufactures lifting and mechanical handling devices for Defence, Civil Aviation and Industrial Safety markets. Their products are used worldwide for the safe handling of weapons, aircraft engines, personnel and high-value loads. Recent projects include bespoke military transport packaging for missiles and armour, and a Purge Air System developed in collaboration with Airbus for working within aircraft fuel tanks.
This is not an environment where “close enough” exists as a concept. When a technical manual describes the procedure for lifting a missile onto a transport vehicle, every measurement, every torque specification, every safety warning must be rendered with absolute fidelity in the target language. The personnel following these instructions may not have access to the English original. The translation is the document.
Bubbles has translated Didsbury’s mission-critical technical manuals since 2008, working across a wide range of international languages for clients including Airbus. The content demands translators with genuine engineering domain knowledge — not linguists who can look up terminology, but specialists who understand the underlying mechanical principles and can render them naturally in the target language.
Equally valuable is the reverse translation capability. Didsbury competes for international contracts, and the tender documentation — Invitations to Tender, RFQs and RFPs — frequently arrives in languages other than English. Bubbles translates these documents into English, enabling Didsbury’s bid teams to understand precise requirements and respond with properly targeted proposals. In competitive procurement, the quality of the translation directly affects the quality of the bid. Misunderstand a specification and the proposal misses the mark. Misinterpret a compliance requirement and the bid may be disqualified entirely.
This two-directional workflow — English outbound for technical documentation, foreign languages inbound for tender responses — is characteristic of specialist engineering firms operating in global markets.
Meggitt Polymers and Composites: Quality Assurance Across Continents
Meggitt is a global FTSE-100 engineering group manufacturing components and sub-systems for extreme environments across aerospace, defence and energy sectors. With 10,000 staff distributed across Asia, Europe and North America, maintaining consistent documentation quality is a structural challenge, not merely a linguistic one.
Bubbles already worked with Meggitt’s UK and US divisions when a new requirement emerged. The Chinese division’s technical documentation quality needed independent analysis. The question was not whether the content existed — it did — but whether it met the same rigorous standards applied elsewhere in the organisation.
Bubbles established a stringent proofreading process specifically for the Chinese documentation, built around formal discrepancy reports. These reports were designed with dual readability in mind: linguists needed to understand the nature of each error, while QA experts needed to assess its significance within Meggitt’s quality framework. A mistranslated connector type, for instance, would be flagged differently from an inconsistent use of terminology — both matter, but they matter in different ways to different people.
The discrepancy reports provided Meggitt with clear, actionable intelligence. Rather than vague assertions about quality levels, the reports quantified and categorised issues, enabling targeted improvements. The proofreading process itself became a quality tool, not merely a checking mechanism.
The result was measurable. QA processes for the Chinese documentation improved significantly, and Meggitt gained confidence that quality requirements were being met consistently across all operational bases, regardless of language. The framework Bubbles developed could be applied to any division in any language — a scalable approach to a problem that grows with every acquisition and every new market entry.
For a company operating in sectors where component failure can be catastrophic, documentation quality is not a secondary concern. It is part of the engineering.
David Brown Santasalo: Format Innovation at Scale
David Brown Santasalo brings almost 300 years of experience to mechanical power transmission — one of the world’s leading brands in the field. When the company undertook a major new website translation into European, Nordic, Latin American and Far-Eastern languages, the scale of the content demanded a smarter approach than simply translating page by page.
The planning phase alone took over a year. During content creation, Bubbles worked closely with David Brown Santasalo to identify the most cost-effective translation method for a project of this volume. The discussion was practical: how to maintain quality across dozens of language pairs while controlling costs and enabling the translated content to integrate smoothly into the web platform.
After extensive format testing, the decision was made to use XLIFF (XML Localisation Interchange Format). This choice delivered three distinct advantages. First, XLIFF supports translation memory — previously translated segments are stored and reused, reducing both cost and turnaround time on recurring content. Second, it enforces terminology consistency across translators and languages, which matters enormously when technical product descriptions must be precise. Third, and perhaps most practically, XLIFF enables translated text to reflow directly into the web content management system with minimal manual intervention. No reformatting. No copy-pasting. No layout breakage.
To handle the sheer volume of content within the required timeframe, Bubbles established teams of multiple translators per language. This parallel working model, combined with the translation memory benefits of XLIFF, meant that large content batches could be processed rapidly without the quality degradation that typically accompanies rushed timelines.
The project demonstrated that translation at scale is as much an engineering problem as a linguistic one. Choosing the right format, building the right team structure, and investing in upfront planning produced compounding returns throughout the delivery phase.
NIKKEN Kosakusho Europe: Specialist Translators for Specialist Engineering
NIKKEN Kosakusho’s European arm represents a Japanese parent company with over 70 offices worldwide across three continents. Since 1989, they have supplied Europe with precision engineering products: Performance CNC rotary tables, NC tooling solutions, tool presetters, and spindle optimisation systems. Their client industries — aerospace, medical, motorsport, power engineering, oil and gas, mould tool and die — demand absolute technical accuracy.
When NIKKEN approached Bubbles for website translation into European languages, the challenge was immediately apparent. This was not general commercial content with a few technical terms scattered through it. The material was deeply specialist, written by engineers for engineers, dense with terminology specific to CNC machining and precision tooling. A translator who could handle general mechanical engineering might still stumble on the specifics of spindle optimisation or rotary table specifications.
Bubbles assembled translator teams for each target language, selecting only linguists with demonstrable expertise in mechanical and industrial engineering. The selection process mirrored the approach that had proved effective with Siemens: several sample translations were produced per language, each by a different translator. NIKKEN’s country teams — the people who would actually use the translated content and field questions from local customers — reviewed the samples and selected their preferred translator for each language.
This selection process achieved something important beyond quality assurance. It gave NIKKEN’s in-country teams ownership of the translation output. They had chosen the voice that would represent their brand in their market. That investment of time upfront paid dividends throughout the project.
Once approved, translators communicated directly with NIKKEN’s country teams. Technical queries — and there were many, given the specialist nature of the content — were resolved faster because translators and reviewers had established a working relationship. The traditional bottleneck of routing every question through a central project manager was eliminated.
The result was technically precise website content that read naturally in each target language, produced efficiently through a structure designed around the client’s own expertise.
Broady Flow Control: Partnership Through Growth
Broady Flow Control has manufactured valves since 1938 and holds a prominent position as a key defence industry supplier. Their product range — safety valves, pressure reducing valves, pilot operated valves, hydrant valves and naval defence sector valves — serves critical applications where failure is not an acceptable outcome.
When Valvitalia Group acquired Broady in 2010, the company’s ambitions shifted. Global expansion required documentation in languages and markets that Broady had not previously served. After-sales support for an international customer base demanded operating instructions, datasheets and works instructions that were technically precise in every target language.
Bubbles was appointed as preferred translation partner in 2010, the same year as the acquisition. The timing was deliberate. Broady needed a supplier who could scale with them — not a transactional arrangement for individual projects, but a partnership that would grow alongside the business.
Over the years that followed, Bubbles translated datasheets, operating instructions, inspection reports and works instructions into both European and non-European languages. The scope expanded as Broady’s international footprint grew. New markets meant new languages. New products meant new terminology. But the accumulated translation memory and terminology databases from previous projects meant that each new requirement built on existing foundations rather than starting from scratch.
The defence sector context added its own requirements. Documentation for naval valves must meet specific regulatory and safety standards that vary by country. Translators working on this content needed not only linguistic skill and engineering knowledge, but familiarity with the regulatory frameworks governing defence equipment documentation in each target market.
The partnership model — long-term, preferred supplier, scaling with the client — delivered competitive pricing alongside consistent quality. For Broady, translation became an enabler of global expansion rather than an obstacle to it. For Bubbles, the relationship demonstrated that engineering translation partnerships produce their best results when measured in years, not projects.
Patterns and Insights
Six clients, six different challenges, but several themes emerge consistently.
Reverse translation wins contracts. Engineering firms do not only need their own content translated outbound. They need foreign-language tender documentation translated into English so their bid teams can respond accurately. Didsbury’s ability to win international contracts depends partly on understanding precisely what is being asked. This bidirectional requirement is characteristic of the sector and often overlooked by translation providers focused solely on outbound content.
Translator selection is an investment, not an overhead. The sample translation and in-country review process used with Siemens and NIKKEN takes time upfront. It requires producing multiple versions, coordinating with review teams in different countries, and accepting that some translators will not be selected. But the alternative — discovering quality problems after delivery — costs far more in rework, delay and damaged confidence.
Format innovation reduces long-term costs. David Brown Santasalo’s adoption of XLIFF for website translation was not a technical indulgence. It was a commercial decision that reduced per-word costs through translation memory, improved consistency across languages, and eliminated manual reformatting. Engineering firms that treat translation as a formatting problem as well as a linguistic one consistently achieve better value.
Long-term partnerships compound in value. Broady’s decade-plus relationship with Bubbles means that every new project benefits from accumulated terminology, established processes and translators who already understand the client’s products. The same pattern appears with Didsbury and Siemens. First-project costs and timelines are never repeated because the foundation keeps building.
Precision is the baseline, not the aspiration. In engineering translation, measurements, tolerances, material specifications and safety-critical procedures must be rendered exactly. This is not a sector where creative licence improves the output. The translators who succeed are those who combine linguistic fluency with genuine technical understanding — who know not just the words, but what the words mean when someone is following them on a factory floor.
