Subsea production complexes (SPC)

Send request

The SPC technical supervision is carried out in order to classify it, to check the conditions of retainment of class and the SPC compliance with the requirements of the Register during the design, construction, offshore operations during construction (installation), commissioning, operation, modernization, repair, preservation and disposal. 

The SPC technical supervision consists in verifying its compliance with the requirements of the Register in the following cases:

  • review and approval (agreement) of technical documentation;

  • survey of items of technical supervision at the stages of manufacture, construction, operation including modernization and repair.

The Register activities related to the SPC classification and technical supervision are performed under contracts with customers concluded on a voluntary basis.

Technical supervision of the Register during the design, construction and operation of SPC as offshore oil-and-gas facilities on the sea shelves is carried out along with the procedures for supervision of these facilities by the supervision authorities of the Russian Federation in accordance with the requirements of the laws of the Russian Federation. 

Appraisal of design documentation during construction of subsea production complexes (SPC) 

The SPC construction and the manufacture of materials and products for SPC is carried out in accordance with the technical documentation approved (agreed) by RS.

Prior to the technical supervision of the SPC design, construction and/or operation, technical documentation is submitted to RS for review to ensure that the requirements of the Rules for this equipment, materials and products, as well as the quality of the services provided are fully met.

Technical documentation for SPC may be submitted to RS as one of the following options depending on the design stage:

  • justification of investments for offshore field development project;

  • SPC technical design or offshore field development project;

  • SPC detailed design, process documentation and repair-and-renewal operations design;

  • regulatory and technical documents, technical conditions, processes, procedures for SPC processes and maintenance;

  • technical documentation for SPC components, data sheets and operating instructions. 

Documents issued according to the results of the appraisal of design documentation

  • The RS review results for technical documentation are completed by stamping with RS appropriate seals on the documents and/or making a Conclusion Letter. When reviewing technical documentation in electronic form, stamping is done using software tools and certified by an electronic digital signature of the Register’s authorized specialist. 

Technical supervision during manufacture of materials and products for SPC

Technical supervision during manufacture of materials and products only applies to the properties parameters and characteristics, which are regulated by the SPC Rules and indicated in the approved technical documentation. When performing the technical supervision of the manufacture of materials and products for SPC specified in the Technical Supervision Items Nomenclature, RS provides: 

  • review of technical documentation and establishing of compliance with the requirements of the SPC Rules;

  • approval of individual types of SPC equipment with issuance of Certificates of Compliance;

  • approval of welding processes;

  • approval of welding consumables;

  • certification of welders;

  • recognition of laboratories;

  • recognition of firms (manufacturers). 

Documents issued based on the survey results 

  • Certificate of Product Compliance (С, СЗ) - a document that certifies the compliance of specific materials, products or groups of products with the requirements of the RS Rules and regulatory and technical documentation.

  • Type Approval Certificate (СТО) - a document that certifies the compliance of types of products or product groups with the requirements of the RS Rules.

  • Recognition Certificate of Testing Laboratory (СПЛ) - a document that certifies the competence of a laboratory to make certain types of tests of materials and products;

  • Recognition Certificate for Manufacturer (СПИ) - a document that certifies the recognition by RS of a firm as a manufacturer of materials and products for ships under RS technical supervision;

  • Recognition Certificate (СП) - a document that certifies the recognition of a company-service provider, which provides services (performs work) in accordance with RS requirements;

  • Certificate of Firm Conformity (ССП) - a document that certifies the compliance of a company with the RS requirements in providing the declared services (performing the declared work);

  • Certificate of Approval for Welding Consumables (СОСМ) and Welding Procedure Approval Test Certificate (СОТПС) - documents that confirm the compliance of welding consumables and welding processes with the requirements of the RS Rules. 

The RS certificates are issued in electronic or paper format. The RS certificates with electronic digital signature are issued in electronic format only. According to the results of surveys, an email is sent to the customer that contains a direct link to the document.

To ensure the transparency, to simplify the search for documents and to protect against forgery, a unique QR code is applied to the RS Certificates. Freely distributable software (freeware) can be used to read it. 

Technical supervision during construction 

Technical supervision during the SPC construction is carried out on the basis of a contract concluded between RS and a company that is engaged in the SPC construction.

Prior to beginning the technical supervision of the SPC construction, the company shall be audited by RS for compliance with the RS Rules. According to the audit results, a Report is made with the relevant appendix or a Certificate of Firm Conformity can be issued.

In the water areas of the Russian territorial offshore shelf and internal water areas, the RS technical supervision of the SPC construction does not substitute the monitoring by the supervision bodies of the Russian Federation unless otherwise specified by special agreements. 

Documents issued based on the survey results

  • Certificate of SPC survey upon completion of construction;

  • SPC classification certificate. 

Classification surveys in service 

For SPC within the RS class, the maintenance is carried out under the RS technical supervision in the form of periodical surveys. Where necessary (in case of accidents or incidents at SPC), occasional surveys are conducted.      Periodical surveys are carried out by the Register in order to confirm/renew the SPC class. As a rule, RS proposes to the customer to harmonize the system of SPC surveys with the RS periodical classification surveys of FPU/MODU/FOP, from which the SPC are monitored and controlled and/or to which produced formation fluid is supplied.

The basis for the Register to carry out the SPC technical supervision is a contract concluded by the Register with the SPC operator.

While in service, SPC undergo the following surveys:

  • initial;

  • periodic (annual, intermediate and special);

  • occasional. 

A scope of periodical surveys is determined by the Register in accordance with the design features of a particular SPC, its maintenance schedule and the results of previous surveys. 

Documents issued based on the certification results: 

According to the results of the SPC annual/intermediate/special survey, RS makes a Report, which, given positive results of the surveys, confirms the validity of the SPC class for the next annual period, and given positive results of the special survey, extends the validity of the SPC class with the relevant entry made in the Classification Certificate that is valid (with annual confirmation) until the next special survey.
