GL New Rules for Offshore Wind Service Vessels / GL aktualisiert Vorschriften für seegängige Schiffe und Seeschiffe

GL aktualisiert Vorschriften für seegängige Schiffe und Seeschiffe

Der Germanische Lloyd (GL) hat die Vorschriften für Seeschiffe und Marineschiffe mit Wirkung zum 1. Mai 2012 aktualisiert.

Erstmalig wurden Vorschriften für die Klassifikation von Crew Boats erarbeitet. Die überarbeiteten Seeschiffsvorschriften gelten für verschiedene Schiffstypen wie beispielsweise Containerschiffe, Tanker oder Massengutschiffe. Weiterhin sind die GL-Vorschriften jetzt vollständig als Download verfügbar.

Neue Anforderungen für Abgasreinigung und Betriebstests für Containerzurrung

Die Änderungen der Klassifikationsvorschriften für seegehende Schiffe betreffen die Bereiche Klassifikation und Besichtigungen, Rumpfstrukturen, Maschinenanlagen, elektrische Anlagen, Automation, sowie die strukturellen Vorschriften für Containerschiffe und für Laschen von Containern. Sie gelten für alle Schiffsneubauten, die nach dem 1. Mai 2012 bestellt werden.

Die Vorschriften für Maschinenanlagen enthalten jetzt neue Anforderungen für Abgasreinigungssysteme. Diese Anforderungen betreffen den Aufbau des Systems, das Sicherheitskonzept (Gefahrenanalyse), die Materialien und den Umgang mit schädlichen Verfahrenssubstanzen. Die Anforderungen an die Funktionsprüfung an Bord werden ebenfalls behandelt.

In den GL-Vorschriften für das Verstauen und Verzurren von Containern, Anhang C – „Container Stauteile“ – wird ein neuer Standard für Betriebstests für vollautomatische Verriegelungen festgelegt. Die genauer bezeichneten Anforderungen umfassen den Prüfaufbau, das Beladungsszenario und die Prüfkräfte für Druck, Stapelung und Anheben.

Für Containerschiffe wurde in Abschnitt 8 „Bodenstrukturen“ ein neuer Unterabschnitt „D“ eingefügt, in dem die strukturellen Anforderungen für Querstrahlruder spezifiziert werden. In Abschnitt 14 „Ruder und Steueranlage“ wurde ebenfalls ein neuer Unterabschnitt „H“ eingefügt, der sich mit „Einrichtungen zur Verbesserung der Vortriebswirkung“ befasst. Abschnitt 17 „Luken“ wurde aufgrund der neuen IACS Unified Requirement S21A „Beurteilung der Materialstärke von Lukendeckeln und Lukensüllen und Schließvorrichtungen für Laderäume von Schiffen“ umfangreich überarbeitet.

Erstmalig GL-Vorschriften für Crew-Boats

Der GL hat zudem den ersten umfassenden Satz von Vorschriften für die Klassifikation von Crew Boats erarbeitet. Diese Vorschriften wurden entwickelt, indem erstmals alle relevanten GL-Vorschriften und die internationalen Richtlinien und Empfehlungen zusammengetragen wurden, die zur Klassifizierung von Crew Boats verwendet werden können.

            Germany: GL – New Rules for Offshore Wind Service Vessels Posted on May 4th, 2012 with tags europe, Germany, GL, New, News by topic, offshore, Rules, Service, vessels, wind. Germanischer Lloyd (GL) announces the release of the first comprehensive set of classification rules for Crew Boats and Offshore Wind Farm Service Craft. As the energy industry expands and installations are pushed ever further offshore and into more challenging environments, the vessels servicing these installations must be relied upon to operate in wider spectrum of conditions and take on more complex challenges. The rules, which entered into force on 1 May 2012, have been developed by bringing together, for the first time, all of the relevant GL rules and the international codes and recommendations which can be used for the classification of Crew Boats. The rules will allow designers to develop vessels built to the special needs of clients according to the rules with full confidence in the fact that their vessel can meet with classification approval. The Rules have been developed in consultation with the flag states and will contribute to the development of international standards for Crew Boats. Breaking the great variety of crew boat types into 16 types, according to 4 basic parameters – the designer, builder and commissioner of a crew boat can very easily take into account the classification rules which apply to the vessel under consideration. Such a breakdown will allow not only the easy identification of class requirements but a design tailored to meet project specifications and budgets. The main parameters are: the number of non-crew personnel to be carried (below or above 12), the length of the vessel (below or above 24 m), speed (high speed range or below), and the hull form (mono or multihull). The new rules consist of 18 sections with the first two covering general requirements, classification and surveys. Sections 3 to 8 deal with the structural requirements, while sections 9 to 18 cover machinery, electrical and automation systems, in particular as regards the operation of the vessel. In addition special requirements are introduced, such as for bow designs matching the boat landings of offshore structures, as well as special provisions for the s in extreme weather conditions is also covered with a section covering operation in ictransfer of personnel. New GL class notations have been introduced with the Rules, including: “Crew Boat 1”, for vessels which are intended to carry 12 Offshore Support Personnel (OSP) or fewer, “Crew Boat 2”, for vessels intended to carry more than 12 OSP, and “Offshore Wind Farm Service Craft” (OWFSC) for vessels dedicated to wind farm service, restricted to the carriage of 60 OSP or fewer. The class notation “RPw” can also be given to vessels outfitted with two completely independent propulsion systems, which are designed to operate in the vicinity of wind farms. Sections covering the variety of special mechanical equipment used upon Crew Boats have been developed to take into account the specialised requirements of offshore operation, including: personnel transfer systems, stabilisation systems and helicopter winching. The deployment of Crew Boates. in extreme weather conditions is also covered with a section covering operation in ice.

Germany: GL Releases Rules Updates for Seagoing Ships and Naval Vessels

Posted on May 4th, 2012 with tags europe, Germany, GL, Naval, News by topic, releases, Rules, Seagoing, ships, updates, vessels. Germanischer Lloyd (GL) has released updates to its Rules for Seagoing Ships and Naval Vessels. The updated Rules came into effect on 1 May 2012. Changes have been made to the following GL Rules for Seagoing Ships: Classification and Surveys, Hull Structures, Machinery Installations, Electrical Installations, Automation, Structural Rules for Container Ships and Stowage and Lashing of Containers. Additionally, new Rules have been developed for the classification of Crew Boats and Offshore Wind Farm Service Craft. For Naval Ships updates have also been carried out for the following Rules: Classification and Surveys, Propulsion Plants, Electrical Installations, Automation and Ship Operation Installations and Auxiliary Systems. The GL Rules and Guidelines are also available for download for the first time in their entirety. Up to this point the Rules and Guidelines have only been available on a section by section basis. Visitors to Germanischer Lloyd’s website will now be able to download a complete pdf version of any of the individual Rules or Guidelines free of cost. Some of the most notable changes to individual Rules include: the Rules for Machinery Installations now have new requirements for exhaust gas cleaning systems. These requirements address system layout, safety concept (hazard analysis), materials, and handling of noxious process substances. The requirements for functional testing onboard are also covered. In the GL Rules for Stowage and Lashing of Containers, Annex C – “Container Lashing Fittings” – sets out a new standard for operational tests for fully automatic locks. The specified requirements comprise test setup, loading scenario and test forces for compression, racking and lifting. GL’s Structural Rules for Container Ships have undergone major amendment, including the following changes: Section 8 “Bottom Structures” introduces an entirely new sub-section – “D” – which specifies structural requirements for transverse thrusters. In Section 14 “Rudder and Manoeuvring Arrangement”, as well, a new sub-section – “H” – has been added covering “devices for improving propulsion efficiency”. Section 17 “Hatchways” has been extensively revised due to the new IACS Unified Requirement S21A “Evaluation of Scantlings of Hatch Covers and Hatch Coamings and Closing Arrangements of Cargo Holds of Ships”. GL has also released the first comprehensive set of rules for the classification of Crew Boats and Offshore Wind Farm Service Craft. These rules have been developed by bringing together, for the first time, all of the relevant GL rules and the international codes and recommendations which can be used for the classification of Crew Boats. The rules will allow designers to develop vessels built to the special needs of clients according to the Rules with full confidence in the fact that their vessel can meet with classification approval.
