MESC SPE 77/130 February 2016 Page 2 PREFACE MESC (Materials and Equipment Standards and Code) SPE documents reflect the views, at the time of publication, publication, of: Shell Global Solutions International B.V. (Shell GSI) and/or Shell International Exploration and Production B.V. (SIEP) and/or other Shell Service Companies. They are based on the experience acquired during their involvement with the design, construction, operation and maintenance of processing units and facilities, and they are supplemented with the experience of Shell Operating Units. Where appropriate they are based on, or reference is made to, international, regional, national and industry standards. The objective is to set the recommended standard for good design and engineering practice applied by Shell companies operating an oil refinery, gas handling installation, chemical plant, oil and gas production facility, or any other such facility, and thereby to achieve maximum technical and economic benefit from standardization. The information set forth in these publications is provided to Shell companies for their consideration and decision to implement. This is of particular importance where MESC SPEs may not cover every requirement or diversity of condition at each locality. The system of MESC SPEs is expected to be sufficiently flexible to allow individual Operating Units to adapt the information set forth in MESC SPEs to their own environment and requirements. When Contractors or Manufacturers/Suppliers use MESC SPEs they shall be solely responsible for the quality of work and the attainment of the required design and engineering standards. In particular, for those requirements not specifically covered, the Principal will expect them to follow those practices, which will achieve the same level of integrity as reflected in the MESC SPEs. If in doubt, the Contractor or Manufacturer/Supplier shall, without detracting from his own responsibility, consult the Principal or its technical advisor. The right to use MESC SPEs is granted by Shell GSI, in most cases under Service Agreements primarily with Shell companies and other companies receiving technical advice and services from Shell GSI or another Shell Service Company. Consequently, Consequently, three categories of users of MESC SPEs can be distinguished: 1)

Operating Units having a Service Service Agreement with Shell GSI or other Shell Service Company. The use of MESC MESC SPEs by these Operating Units is subject in all respects to the terms and conditions of the relevant Service Agreement.

2)

Other parties who are authorized to use MESC SPEs subject to appropriate contractual contractu al arrangements arrangeme nts (whether as part of a Service Agreement or otherwise). otherwise).

3)

Contractors/subcontractor Contractors/subcontractors s and Manufacturers/Suppliers Manufacturers/Suppliers under a contract with with users referred to under 1) or 2) which requires requires that tenders for projects, materials supplied or - generally - work performed on behalf of the said users comply with the relevant standards.

Subject to any particular terms and conditions as may be set forth in specific agreements with users, Shell GSI disclaims any liability of whatsoever nature for any damage (including injury or death) suffered by any company or person whomsoever as a result of or in connection with the use, application or implementation of any MESC SPE, combination of MESC SPEs or any part thereof, even if it is wholly or partly caused by negligence on the part of Shell GSI or other Shell Service Company. The benefit of this disclaimer shall inure in all respects to Shell GSI and/or any Shell Service Company, or companies affiliated to these companies, that may issue MESC SPEs or require the use of MESC SPEs. Without prejudice to any specific terms in respect of confidentiality under relevant contractual arrangements, MESC SPEs shall not, without the prior written consent of Shell GSI, be disclosed by users to any company or person whomsoever and the MESC SPEs shall be used exclusively for the purpose for which they have been provided to the user. They shall be returned after use, including any copies, which shall only be made by users with the express prior written consent of Shell GSI. The copyright of MESC SPEs vests in Shell GSI. Users shall arrange for MESC SPEs to be held in safe custody and Shell GSI may at any time require i nformation satisfactory satisfactory to them in order to ascertain how users implement this requirement.

DISTRIBUTION, INTENDED USE AND REGULATORY CONSIDERATIONS Unless otherwise authorised by Shell GSI, the distribution of this MESC SPE is confined to Shell companies and, where necessary, to Contractors and Manufacturers/Suppliers nominated by them. This MESC SPE is intended for use in oil refineries, chemical plants, gas plants, exploration and production facilities and, where applicable, supply/distribution installations. If national and/or local regulations exist in which some of the requirements may be more stringent than in this MESC SPE the Contractor shall determine by careful scrutiny which of the requirements are the more stringent and which combination of requirements will be acceptable with regards to safety, environmental, economic and legal aspects. In all cases the Contractor shall inform the Principal of any deviation from the requirements of this MESC SPE which is considered to be necessary in order to comply with national and/or local regulations. The Principal may then negotiate with the Authorities concerned, the objective being to obtain agreement to follow this MESC SPE as closely as possible.

1.3
