Small craft - Hull construction and scantlings - Part 7: Determination of loads for multihulls and of their local scantlings using ISO 12215-5 (ISO 12215-7:2020)
This document defines the dimensions, local design pressures and global loads acting on multihull craft with a hull length (LH) or load line length of up to 24 m (see Note). It considers all parts of the craft that are assumed watertight or weathertight when assessing stability, freeboard and buoyancy in accordance with ISO 12217 (all parts). Scantlings corresponding to the local design pressures are then assessed using ISO 12215-5.
NOTE The load line length is defined in the OMI "International Load Lines Convention 1966/2005", it can be smaller than LH for craft with overhangs. This length also sets up at 24 m the lower limit of several IMO conventions.
This document is applicable to multihulls built from the same materials as in ISO 12215-5, in intact condition, and of the two following types:
— recreational craft, including recreational charter vessels;
— commercial craft and workboats.
It is not applicable to multihull racing craft designed only for professional racing.
This document is applicable to the structures supporting windows, portlights, hatches, deadlights and doors.
For the complete scantlings of the craft, this document is intended to be used in conjunction with ISO 12215-8 for rudders, ISO 12215-9 for appendages of sailing craft and ISO 12215-10 for rig loads and rig attachment in sailing craft. ISO 12215-6 can be used for additional details.
Throughout this document, unless otherwise specified, dimensions are in (m), areas in (m2), masses in (kg), forces in (N), moments in (Nm), Pressures in (kN/m2) (1 kN/m2 = 1 kPa), stresses and elastic modulus in (N/mm2) (1 N/mm2 = 1 MPa).
Kleine Wasserfahrzeuge - Rumpfbauweise und Dimensionierung - Teil 7: Bestimmung der Lasten für Mehrrumpffahrzeuge und ihrer lokalen Dimensionierungen unter Anwendung der ISO 12215-5 (ISO 12215-7:2020)
Dieses Dokument definiert die Abmessungen, lokalen Entwurfsdrücke und globalen Lasten, die auf Mehrrumpfboote mit einer Rumpflänge (LH) oder Länge der Konstruktionswasserlinie von bis zu 24 m wirken (siehe Anmerkung). Es berücksichtigt alle Teile des Wasserfahrzeugs, die bei der Beurteilung der Stabilität, des Freibords und des Auftriebs in Übereinstimmung mit ISO 12217 (alle Teile) als wasserdicht oder witterungsbeständig angenommen werden. Wasserfahrzeuge, die den lokalen Entwurfsdrücken entsprechen, werden anschließend nach ISO 12215 5 geprüft.
ANMERKUNG Die Länge der Konstruktionswasserlinie ist in der „International Load Lines Convention 1966/2005“ der IMO festgelegt und kann bei Wasserfahrzeugen mit Überhang kleiner als LH sein. Diese Länge legt darüber hinaus bei 24 m die untere Grenze verschiedener IMO Konventionen fest.
Dieses Dokument gilt für Mehrrumpfboote, die aus denselben Werkstoffen wie in ISO 12215 5 gebaut sind und im intakten Zustand sind sowie einem der beiden folgenden Typen angehören:
- Sportboote, einschließlich Charter-Sportboote;
- gewerbliche Wasserfahrzeuge und Arbeitsboote.
Es ist nicht auf rein für professionelle Rennen ausgelegte Mehrrumpf Rennboote anwendbar.
Dieses Dokument ist anwendbar auf die Tragwerke von Fenstern, Bullaugen, Klappen, Seeschlagblenden und Türen.
Für die kompletten Dimensionierungen des Wasserfahrzeugs ist dieses Dokument für die Anwendung in Verbindung mit ISO 12215 8 für die Ruder, ISO 12215 9 für die Anhänge von Segelbooten und ISO 12215 10 für Takelagelasten und Takelagezubehör von Segelbooten vorgesehen. ISO 12215 6 kann für weitere Einzelheiten herangezogen werden.
In diesem Dokument, und sofern nicht anders festgelegt, sind die Abmessungen in (m), Flächen in (m2), Massen in (kg), Kräfte in (N), Momente in (Nm), Drücke in (kN/m2) (1 kN/m2 = 1 kPa), Spannungen und Elastizitätsmodule in (N/mm2) (1 N/mm2 = 1 MPa) angegeben.
Petits navires - Construction de la coque et échantillonnage - Partie 7: Détermination des charges des multicoques et de leur échantillonnage local en utilisant l'ISO 12215-5 (ISO 12215-7:2020)
Ce document définit les dimensions, les pressions de conception locales et les charges globales agissant sur les bateaux multicoques d'une longueur de coque (LH) ou une longueur de référence jusqu'à 24 m (voir la Note). Il prend en compte toutes les parties du bateau qui sont considérées étanches à l'eau ou aux intempéries lors de l'évaluation de la stabilité, du franc-bord et de la flottabilité conformément à l'ISO 12217 (toutes les parties). Les échantillonnages correspondant aux pressions nominales locales sont ensuite évalués à l'aide de l'ISO 12215-5.
NOTE La longueur de référence est définie dans la «Convention internationale sur les lignes de charge 1966/2005» de l'OMI, elle peut être plus petite que LH pour des bateaux ayant des élancements. Cette longueur établit également à 24 m, la limite inférieure de plusieurs Conventions Internationales de l'OMI.
Ce document est applicable aux multicoques construits à partir des mêmes matériaux que dans l'ISO 12215-5 à l'état intact et des deux types suivants:
— les bateaux de plaisance, y compris les bateaux de location avec skipper («charter»);
— les bateaux à usage commercial et les bateaux de travail.
Il ne s'applique pas aux multicoques de course conçus uniquement pour les courses avec équipage professionnel.
Ce document est applicable aux structures supportant des fenêtres, hublots, panneaux, tapes et portes.
Pour un échantillonnage complet du bateau, le présent document est destiné à être utilisé conjointement avec l'ISO 12215-8 pour les gouvernails, l'ISO 12215-9 pour les appendices des voiliers et l'ISO 12215-10 pour les charges dans le gréement et les points d'ancrage du gréement. L'ISO 12215-6 peut être utilisée pour des détails supplémentaires.
Dans tout le présent document et sauf spécification contraire, les dimensions sont en (m), les surfaces en (m2), les forces en (N), les moments en (Nm), les pressions en kN/m2 (1kN/m2 = 1 kPa), les contraintes et modules d'élasticité en N/mm2 (1N/mm2 = 1 Mpa).
