This International Standard establishes all of the steps needed to properly measure and account for the quantities of cargoes on liquefied natural gas (LNG) carriers. This includes, but is not limited to, the measurement of liquid volume, vapour volume, temperature and pressure, and accounting for the total quantity of the cargo on board. This International Standard describes the use of common measurement systems used on board LNG carriers, the aim of which is to improve the general knowledge and processes in the measurement of LNG for all parties concerned. This International Standard provides general requirements for those involved in the LNG trade on ships and onshore.

This part of ISO 19901 provides requirements, guidance, and information for the design and, fabrication of topsides structure for offshore structures. It complements ISO 19902, ISO 19903, ISO 19904-1,
ISO 19905-1 and ISO 19906, which provide requirements for various forms of substructure.
The actions on topsides structure, and the action effects in the structural components are derived from this part of ISO 19901, where necessary in combination with other International Standards in the ISO 19901 series.
The resistances of non-cylindrical structural components of the topsides structure can be determined by the use of national building standards, as specified in this part of ISO 19901.
The resistance of cylindrical structural components are to be in accordance with ISO 19902 but may be according to national building standards, as specified in this part of ISO 19901.
This part of ISO 19901 is applicable to the following:
— topsides of fixed offshore structures;
— discrete structural units placed on the hull structures of floating offshore structures and mobile offshore units;
— topsides of arctic offshore structures, excluding winterization ( ISO 19906).
If any part of the topsides structure forms part of the primary structure of the overall structural system which resists global platform actions, the requirements of this part of ISO 19901 are supplemented with applicable requirements in ISO 19902, ISO 19903, ISO 19904-1, ISO 19905-1 and ISO 19906.
This part of ISO 19901 does not apply to those aspects of topsides structure that form part of the overall structural system of floating offshore structures and mobile offshore units that are governed by the rules of a recognized certifying authority and which are within class rules.
The fire and explosion provisions of this part of ISO 19901 can however be applied to those parts of the hulls of floating offshore structures and mobile offshore units that contain hydrocarbon processing, piping or storage.
This part of ISO 19901 addresses the following aspects of topsides structure:
— design, fabrication, installation and modification;
— prevention, control and assessment of fire, explosions and other accidental events.
NOTE Requirements for structural integrity management are presented in ISO 19901-9.
This part of ISO 19901 applies to structural components including the following:
— primary and secondary structure in decks, module support frames and modules;
— flare structures;

— crane pedestal and other crane support arrangements;
— helicopter landing decks (helidecks);
— permanent bridges between separate offshore structures;
— masts, towers and booms on offshore structures.

This document specifies a test method for the determination of the electrical conductivity in anhydrous fuel ethanol (volume fraction maximum of 1 % water content) and its mixtures with hydrocarbons, and for hydrous fuel ethanol (volume fraction maximum of 5 % water content), in the range of 0,3 μS cm−1 to 5 μS cm−1 at a temperature of 25 °C. The electrical conductivity is determined from the measured electrical conductance.

This document covers topside systems for fixed or floating offshore projects not covered by class requirements. This document is also applicable for hull systems and onshore projects provided that there is no cost increase in its application. This document is not to be considered or confused with class
rules from classification societies. For verification of compliance with class rules, it is best to use the respective class rules from class societies.
This document was developed based on major international standards to comply with requirements of shelf regulations of UK, US, Norway and Australia. Overall the requirements outlined in this document will meet most of the specified regulatory requirements. Exemptions where requirements in common standards for tertiary items applied in offshore oil & gas projects are not met in this document are clearly stated.
This document provides requirements to dimensions of the items but does not include requirements to clearances with other structures. Material selection is limited to references with more detailed information to be found in this document, material requirement in clauses 6 and 7.
The following tertiary outfitting designs for equipment items are covered in this document:
— handrails;
— safety gate;
— stairs;
— spiral stairs;
— vertical ladder;
— grating;
— manhole;
— connection method.

This document describes the functional requirements for pipelines for maximum operating pressure over 16 bar. This document also describes the mechanical requirements for pipework in stations with a maximum operating pressure greater than 16 bar.
NOTE Welding requirements are described in EN 12732. Functional requirements for stations are given in EN 1776, EN 1918-5, EN 12186, and EN 12583.
This document is applicable for transporting gas via onshore high-pressure steel pipeline infrastructures, where the following applies:
— onshore:
• from the point where the pipeline first crosses what is normally accepted as battery limit between onshore and offshore, and that is not located within commercial or industrial premises as an integral part of the industrial process on these premises except for any pipelines and facilities supplying such premises;
• pipeline system with a starting point onshore, also when parts of the pipeline system on the mainland subsequently cross fjords, lakes, etc.
— high pressure: gas with a maximum operating pressure over 16 bar and a design temperature between −40 °C and 120 °C.
— steel pipeline infrastructure: infrastructure consisting of pipeline components, such as pipes, valves, couplings and other equipment, restricted to components made of unalloyed or low alloyed carbon steel and joined by welds, flanges or mechanical couplings.
— gas: non-corrosive natural gas, biomethane gas, hydrogen gas and mixtures of these gases where technical evaluation has ensured that operating conditions or constituents or properties of the gas do not affect the safe operation of the pipeline.
Gas infrastructures covered by this document begin after the gas producer's metering station. The functional demarcation of the pipeline system within a plant area is usually directly after the first isolating valve of the installation, but can differ in particular situations.
A schematic representation of pipelines for gas infrastructure is given in Figure 1.
This document can also be applied to the repurposing of existing pipelines.

This document specifies common basic principles for gas infrastructure. Users of this standard are expected to be aware that more detailed national standards and/or code of practice can exist in the CEN member countries.
This document is intended to be applied in association with these national standards and/or codes of practice setting out the above-mentioned basic principles.
In the event of conflicts in terms of more restrictive requirements in national legislation/regulation with the requirements of this standard, the national legislation/regulation takes precedence as illustrated in CEN/TR 13737.
CEN/TR 13737 gives:
- clarification of all legislations/regulations applicable in a member state;
- if appropriate, more restrictive national requirements;
- a national contact point for the latest information.
