EN ISO 19901-5:2021

Petroleum and natural gas industries - Specific requirements for offshore structures - Part 5: Weight management (ISO 19901-5:2021)

This document specifies requirements for managing and controlling the weight and centre of gravity (CoG) of offshore facilities by means of mass management during all lifecycle phases including; conceptual design, front end engineering design (FEED), detail engineering, construction and operations. These can be new facilities (greenfield) or modifications to existing facilities (brownfield).
Weight management is necessary throughout operations, decommissioning and removal to facilitate structural integrity management (SIM). The provisions of this document are applicable to fixed and floating facilities of all types.
Weight management only includes items with static mass.
Snow and ice loads are excluded as they are not considered to be part of the facility. Dynamic loads are addressed in ISO 19904-1, ISO 19901-6 and ISO 19901-7.
This document specifies:
a) requirements for managing and controlling weights and CoGs of assemblies and entire facilities;
b) requirements for managing weight and CoG interfaces;
c) standardized terminology for weight and CoG estimating and reporting;
d) requirements for determining not-to-exceed (NTE) weights and budget weights;
e) requirements for weighing and determination of weight and centre of gravity (CoG) of tagged equipment, assemblies, modules and facilities;
This document can be used:
f) as a basis for costing, scheduling or determining suitable construction method(s) or location(s) and installation strategy;
g) as a basis for planning, evaluating and preparing a weight management plan and reporting system;
h) as a contract reference;
i) as a means of refining the structural analysis or model.

Industries du pétrole et du gaz naturel - Exigences spécifiques relatives aux structures en mer - Partie 5: Gestion des poids (ISO 19901-5:2021)

Le présent document spécifie les exigences relatives à la gestion et au contrôle du poids et du centre de gravité (CdG) des installations en mer par la gestion des masses pendant toutes les phases du cycle de vie, notamment l'étude conceptuelle, l’étude avancée de détail (FEED), l'ingénierie de détail, la construction et les opérations. Ces structures peuvent être des installations nouvelles ou des modifications d’installations existantes (zones de réhabilitation).
La gestion des poids est nécessaire tout au long des opérations, mais également au cours des phases de démantèlement et d'enlèvement, afin de faciliter la gestion de l'intégrité structurelle (GIS). Les dispositions du présent document s'appliquent aux installations fixes et flottantes de tous types.
La gestion des poids ne concerne que les éléments ayant une masse statique.
Les charges associées à la neige et à la glace sont exclues, car elles ne sont pas considérées comme faisant partie de l’installation. Les charges dynamiques sont traitées dans l'ISO 19904-1, ISO 19901-6 et l'ISO 19901-7.
Le présent document spécifie:
a) les exigences applicables à la gestion et au contrôle des poids et des CdG des ensembles et des installations entières;
b) les exigences applicables aux interfaces de la gestion des poids et du CdG;
c) une terminologie normalisée pour l'estimation et l'établissement de rapports relatifs aux poids et aux CdG;
d) les exigences applicables à la détermination des poids à ne pas dépasser (NTE) et des poids prévisionnels;
e) les exigences applicables à la pesée et à la détermination du poids et du centre de gravité (CdG) des équipements identifiés, des ensembles, des modules et des installations.
Le présent document peut être utilisé:
f) comme base d'établissement des coûts, de planning ou de détermination de méthode de construction ou de localisation(s) appropriés et de stratégie d'installation;
g) comme base de planification, d'évaluation et de préparation d'un plan de gestion des poids et d'un système de suivi;
h) comme référence de contrat;
i) comme moyen d'amélioration de l'analyse structurelle ou du modèle de calcul.

Industrija za predelavo nafte in zemeljskega plina - Posebne zahteve za naftne ploščadi - 5. del: Upravljanje teže (ISO 19901-5:2021)

Ta dokument določa zahteve za upravljanje oziroma nadzor teže in težišča (CoG) obratov na morju z upravljanjem mase v vseh fazah življenjskega cikla, vključno s konceptualnim načrtovanjem, predprojektnim inženirskim načrtovanjem (FEED), načrtovanjem za izvedbo, izdelavo in obratovanjem. To so lahko novi obrati (greenfield) ali spremenjeni obstoječi obrati (brownfield). Upravljanje teže je potrebno med obratovanjem, izločitvijo iz uporabe in odstranitvijo, da se olajša upravljanje strukturne celovitosti (SIM). Določbe tega dokumenta se uporabljajo za vse vrste fiksnih in plavajočih obratov. Upravljanje teže vključuje samo elemente s statično maso. Snežna in ledna obtežba sta izključeni, saj se ne štejeta za del objekta. Dinamične obtežbe so obravnavane v standardih ISO 19904-1, ISO 19901-6 in ISO 19901-7. Ta dokument določa: a) zahteve za upravljanje oziroma nadzor teže in težišča sestavov ter celotnih objektov; b) zahteve za vmesnike za upravljanje teže in težišča; c) standardizirano terminologijo za ocenjevanje teže in težišča ter poročanje; d) zahteve za določanje največje teže (NTE, not-to-exceed) in proračunske teže; e) zahteve za tehtanje oziroma določanje teže in težišča označene opreme, sestavov, modulov ter objektov. Ta dokument je mogoče uporabiti: f) kot osnovo za izračun stroškov, načrtovanje ali določanje ustreznih načinov in lokacij gradnje ter strategije instalacije; g) kot osnovo za načrtovanje, vrednotenje in pripravo načrta upravljanja teže ter sistema poročanja; i) kot sredstvo za izboljšanje strukturne analize ali modela.
