About US


The overall main objective of the JIP is to reduce cost and increase predictability without compromising quality and safety in international offshore EPC projects by using standardized materials, design and procedures for construction and commissioning.

The JIP aims to address differences in requirements between different industry standards (e.g. ISO and API) as well as differences in operator's requirements. The JIP seeks input from Operator's requirements and specifications through the Technical Advisory Group..

Large variations in requirements are a result of many different factors such as too many standards, lack of standards, different regulatory regimes and different owner's requirements. This JIP will aim to reduce the number and variations in requirements to the minimum necessary to reflect a common and global best practice for offshore EPC projects.

Geographical and operational differences related to climate and weather as well as unique country specific requirements will be addressed as separate requirements.

This scope covers topside systems for fixed or floating offshore oil and gas projects. The JIP does not cover hull and hull systems covered by class requirements. The JIP Parties will review the following rules and regulations as basis for developing unified requirements.

  • Internationally recognized standards such as ISO and API
  • Local rules and regulations for key areas such as Gulf of Mexico, North Sea and Australia
  • Operator's requirements
  • Class rules (For reference only)

Deviations between international standards, rules and regulations and operator's requirements will be identified. The JIP aims to establish requirements which will meet the most commonly applied international standards and to minimize deviations in requirements in general. Resolving any deviations between international standards, rules and regulations by way of changing class rules, international standards and local rules and regulations is not part of the JIP.

For the avoidance of doubt, the deliverables from the project must not be considered or confused with class rules from classification societies. For verification of compliance with class rules, the respective class rules from class societies must be used.

It should be noted that this JIP initiative will not aim to develop new standards in areas where existing internationally recognized standards already exists. Moreover, in cases where several international standards are used, this project will aim to identify and recommend a common denominator amongst different international standards.

The EPC phase of offshore projects will be the focus for the JIP. However, the results are expected to be applicable for all phases in an offshore development project. Standards will be developed for simple bulk components and equipment as well as procedures related to construction and commissioning and documentation requirements.

The deliverables from this JIP in the form of IOSS documents should be considered as an intermediate step towards global offshore oil & gas standardization. These may first be published as offshore standards in the name of class societies such as DNV GL, ABS, BV and LR, which can be referred to or adopted by other international standards, e.g. ISO. The long term goal is to further develop internationally recognized standard specifications such as ISO and to minimize additional overlay requirements.
