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. On the same date, the classification company released the first comprehensive set of classification rules for Crew Boats and Offshore Wind Farm Service Craft.

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.
For Naval Ships updates have also been carried out for the following Rules:

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.

New Rules for Crew Boats and Offshore Wind Farm Service Craft

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.

16 Crew Boat Types

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).

Contents of the Crew Boat Rules

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 transfer of personnel.
