What are the typical aspects related to the completeness of delivery documents for new units?

In new projects that involve compressors, there is often an awkward situation: after winning the bid commercially and manufacturing the equipment, when it is delivered to the site and unpacked, compressor manufacturers tend to fall short compared to foreign manufacturers in terms of the documentation provided; they either lack various certificates of conformity or some lists of instruments and other related documents. Foreign manufacturers such as Delaisley provide very comprehensive and thorough delivery materials (in print and electronic format), which greatly facilitates the daily equipment management for our technical staff. I’ve been discussing a project recently, and in order to ensure that compressor manufacturers provide complete final documentation, I plan to include a requirement regarding this in the technical agreement. I’d like to ask everyone: what requirements do you usually have when discussing technical agreements? Is there a template with comprehensive requirements for the delivery of crew information? Thank you all! ~
There are many reasons why one simply doesn’t want to disclose everything: first, to prevent other competitors from stealing the technology； II. I’ll still have to turn to them if I have any problems in the future.
This part is quite troublesome; I’ve encountered it too. Often, the drafting of technical agreements for large-scale units is carried out with the assistance of design institutes. Since the design takes into account the mass of the unit itself, no special constraints are imposed on the auxiliary equipment and accessories. The main issue that arose after the unit arrived was that while the documentation related to the unit itself was quite complete, there was a serious lack of documentation for the auxiliary equipment. From the perspective of the turbine manufacturer, the auxiliary equipment is also purchased externally. If the procurement department is responsible, it will gather as much information as possible for you; but if they are careless, this information can get lost before it even reaches your site. Suggestion: Specify at the time of ordering that no delivery will be made without the necessary materials. It’s hard to say whether it will work, because some compressor manufacturers are quite good at what they do; it’s already great that they send you all the necessary components, so why would they not want to take payment? Just wait; who can keep up with this!
1. There’s no need to talk about domestic manufacturers of large compressors – before signing the technical contract, they agree to whatever you ask for, but once production starts, they can do nothing at all; it’s simply terrible! It is recommended to import critical equipment directly; firstly, the quality is excellent, and secondly, the accompanying documentation is comprehensive, which is of great help to our equipment managers. 2. The technical specifications must include all necessary documents to avoid any issues where they are not provided later on. It mainly includes: machinery, electrical systems, instrumentation, and process operation manuals. Materials specific to different specialties are requested to be filled out by technicians in those specialties, and once everything is gathered, it’s fine to put it all together in a single table!
The using unit and the manufacturing unit have different perspectives: the using unit prefers as detailed information as possible, even requesting drawings of spare parts. The manufacturing unit, however, is reluctant to provide internal details of the equipment due to concerns regarding technical confidentiality and the desire for long-term cooperation; it only provides the information necessary for engineering design. Both sides have valid reasons for their positions. When signing the technical annexes, the two parties can negotiate to provide as much information as possible without violating their respective management regulations. But some stubborn manufacturing units would rather avoid signing a contract than share their internal information
Indeed, as the people above have said, domestic compressors show a good attitude during the initial stage of signing the technical agreements. However, once the contract is won through commercial negotiations and the products are manufactured and delivered, issues such as missing components arise, causing significant inconvenience and trouble for the customers. The attitude before and after is too drastic! ~
There are detailed regulations for SH3501, which can be referred to; those in the petrochemical industry should strictly comply with them.
I’m sorry, I downloaded the SH3501 you mentioned and took a look at it. The standard in question is \"SH3501-2002 Specifications for the Construction and Acceptance of Pipelines for Toxic and Flammable Media in the Petrochemical Industry\", and its contents deal entirely with pipeline-related requirements; it does not cover compressor units. Moreover, the handover documents only mention it briefly without including the necessary information.
