Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of
ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights
in respect thereof. As of the date of publication of this document, ISO had not received notice of (a) patent(s)
which may be required to implement this document. However, implementers are cautioned that this may not
represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 19008:2016), which has been technically
revised.
The main changes are as follows:
— Clause 1— Clause 1:: previous Clause 1Clause 1 extended to also cover lower carbon energy;

Introduction
The oil and gas industries including petrochemical and lower carbon energy activities involve large capital
expenditure (CAPEX) as well as operating expenditure (OPEX).
The purpose of the standard cost coding system (SCCS) is to enable collecting, organizing and reporting the
costs of project development and operations, allowing for the analysis and comparison across projects and
assets. The SCCS can also be utilized to capture additional data like physical quantities, contextual information
or cost classification information. This facilitates the development and benchmarking of unit costs and cost
metrics.
The SCCS is composed of three complementary and disjoint sub-classifications, known as facets:
a) a) physical assets, coded by the physical breakdown structure (PBS);
b) b) activities, coded by the standard activity breakdown structure (SAB);
c) c) resources, coded by the code of resource structure (COR).
This document contains the principles and usage of the SCCS. It also includes implementation requirements
for the expansion of the coding system by individual organizations.
The annexes include:
— Annexes A— annex A, B, B and CC specify the SCCS codes, their names and descriptions;
— Annex D— annex D specifies typical relationships between the SCCS facets;
— Annex E— annex E provides examples of use of the codes.
Application of this document can also be useful when performing production assurance, reliability
management, and life cycle costing; see ISO 20815, ISO 14224 and ISO 15663.

Oil and gas industries including lower carbon energy — Standard cost
coding system
1 Scope
This document specifies the standard cost coding system (SCCS) that classifies costs, work hours and
quantities for the assets and operations associated with the oil and gas industries including lower carbon
energy activities. This document covers all life cycle phases of the assets and operations.
The SCCS is applicable to:
— — cost estimation;
— — benchmarking;
— — cost monitoring and reporting;
— — collection of quantities, work hours and cost data;
— — exchange of cost data among organizations;
— — implementation in cost systems.
This document also provides a basis for the establishment of:
— — cost classification relevant to cost accounting rules, specific contractual agreements, local
requirements for cost reporting to national bodies, government rules and tax regulations, authorization
for expenditure, billing purposes, etc.;
— — unique project breakdown structures (e.g. work breakdown structures, contract breakdown
structures and organizational breakdown structures) or asset breakdown structures (e.g. tag or system
codes and area or module breakdown structures).
This document is intended for the following users:
— — operators or owners;
— — contractors;
— — vendors, manufacturers or suppliers;
— — authorities or regulatory bodies;
— — benchmarking companies;
— — consultants.
