The Technical Specification Was Translated. The Requirements Were Not.
Quote from chief_editor on May 4, 2026, 12:38 amInternational buyers provide technical specifications in English to Chinese manufacturers. Professional translation preserves the words. Engineering knowledge is required to preserve the requirements.
The specification for a heat recovery steam generator at a combined heat and power plant in South Korea ran to 180 pages. It had been written by a German engineering firm — precise, comprehensive, with terminology grounded in DIN and EN standards. The Korean buyer provided it to the Wuhan boiler manufacturer with a Chinese translation prepared by a professional translation service.
The translation was technically accurate — every English word had been rendered into an appropriate Chinese equivalent. What the translation did not capture was the engineering context of certain compound requirements: phrases like "shall be shop-tested to demonstrate steam flow capacity in accordance with the manufacturer's approved test procedure" read in Chinese as a requirement to conduct a test, without conveying that "approved test procedure" in a German engineering context means a procedure that has been reviewed and agreed with the buyer's engineer before the test is conducted. In Chinese boiler manufacturing practice, a test procedure is a factory-developed document that the manufacturer applies without prior buyer review.
The test was conducted. The capacity was demonstrated. The manufacturer's test procedure — which the Wuhan team had developed and applied without providing it to the buyer's engineer for review — used ambient conditions that were outside the specified range for the test. The test result was technically correct under the conditions used and not directly comparable to the conditions under which the plant would operate.
Precision in Language Is Not Precision in Engineering Understanding
The gap between a literal translation and an engineering-equivalent translation is most pronounced for terms that carry implicit context within a specific engineering tradition. German process plant specifications are written within a framework — DIN standards, VGB guidelines, TÜV verification practices — where certain phrases have established procedural meanings that are understood by German-trained engineers without being stated explicitly.
A Chinese engineer trained in China reads the same translated phrase within a different framework — GB standards, Chinese boiler codes, SEPCO and SHENERGY project conventions. The translated word is the same; the professional context attached to it is different. Where those contexts diverge, the translation is accurate and the requirement is misunderstood.
In the HRSG case, the divergence was in the concept of "approved" — a word that carries procedural weight in German engineering practice (review, discussion, formal sign-off) and carries a simpler meaning in the Wuhan manufacturer's normal working practice (internally generated and acceptable to the manufacturer's QA department). The specification meant one thing. The translation said the same words. The manufacturer did something that satisfied the translation and did not satisfy the specification.
The Capacity Dispute Added 14 Months to the Project
The steam capacity test dispute — the buyer's engineer challenging the test methodology, the Wuhan manufacturer defending the test as compliant with the specification, both sides technically defensible within their own engineering frameworks — took 14 months to resolve. The resolution involved: a joint witness re-test using a procedure reviewed and agreed by both parties before the test was conducted, a supplementary thermal analysis to demonstrate the as-built HRSG's expected performance at the plant operating conditions, and a commercial settlement for the delay.
The settlement cost to the Wuhan manufacturer: $1.2 million in schedule adjustments and performance guarantees. The delay cost to the Korean buyer in delayed plant startup revenue: approximately $3.8 million.
The phrase that caused it — "approved test procedure" — is four words in English. In the translation, it was four words in Chinese. The difference between them was 14 months.
A translation converts language. Engineering requirements transfer when the receiving engineer understands the requirement's engineering context. Both are necessary. Only one is in the translation service's scope.
