Sealine and pipeline certification

RINA SERVICES offers certification services for design, construction and installation of Oil and Gas facilities, aimed to the transmission between plants both onshore and offshore. The most challenging projects are related to deep-water sealines, typically installed by S-lay or J-lay method from specialized naval units (laying barges).

The sealine and pipeline certification is normally provided to cope with the risks related to the different realization phases of an offshore project:
  • design of pipeline and relevant components essential to the system's integrity and safety
  • fabrication of pipes and components (spools, SSIV, PLEM)
  • transportation and installation at offshore site.


Certification of a pipeline, by performing a third party independent review of the project, has the main purposes to:
  • ensure that the industrial plant is operating in a socially sensitive scenario
  • ensure that the pipeline or sealine will respect objective parameters of safety, in order to reduce as low as reasonably possible the risk to human life and environment
  • eventually allow the owner to be facilitated in the permission and insurance processes
  • maximise the commitment of an organisation and protects it from unqualified competition.


RINA SERVICES has been providing certification for pipelines for many years, by means of a team of experts with deep knowledge of international standards and rules, such as API or ISO.

Our technicians are familiar with the issues related to the marine environment and they verify that the structural design of the pipeline system meets established standards.

Over time, our team has developed its own detailed certification rules and guidelines, periodically updated according to the most recent improvements in industry research and standardization. Additionally, other internationally recognized Codes and Standards are used as reference, depending on the item under verification, so that appropriate reference code is agreed according to the project specification.


Sealine and pipeline certification covers the project throughout all stages, from design to procurement, from construction to operation, and can even be extended beyond the project life cycle, if the operator requires a re-qualification of the plant beyond its original design life.

RINA design appraisal is based on the review of the design documentation and on independent checks, performed by expert personnel with the help of highly specialized software.

Following the design appraisal, the procurement, transportation and installation phases may be supervised by our surveyors in order to verify and certify the compliance of the facility with the approved drawings and specifications.


Is the certification applicable to an existing oil and gas facility?
Yes, in this case a specific assessment shall be carried out with respect to the actual status of the pipeline, through appropriate surveys and engineering analyses for the definition of the residual lifetime.

​What kind of documentation is required by RINA Services in order to issue the certification?
For the design certificate, our assessment shall cover appropriate documentation to verify the respect of the objective safety levels, as provided in reference codes and standards, i.e. drawings, specifications and calculation reports covering the analyses and verification required by the applicable standards.
