Besides FEM, GL employs numerous other methods and procedures. In hydrodynamics, for example, potential theory methods and finite volume simulations are used for computations. The procedures used allow, for example, simulation of a ship’s motion and loads in seaway and predictions of rudder and propeller cavitation or the circulation of air in an engine room. GL uses its extensive mechanical expertise, among other things, to carry out long-term measurements for R&D purposes and damage analysis. All these procedures have now been written into powerful, user-friendly software tools that speed up processes, minimize mistakes and improve quality.
2. Success story. The Becker rudder not only weighs less and improves manoeuvrability. The twisted rudder also reduces material fatigue due to cavitation. In his eulogy, GL’s Executive Board Member Dr Hermann J. Klein congratulated Dirk Lehmann, Managing Partner, Becker Marine Systems: “With its twisted rudder design, Becker is helping to make ships more efficient, and in particular, more environment-friendly.” The first container vessel to be equipped with the innovative Becker rudder was the “Savannah Express” launched in 2005. In the meantime, 50 other ships have been fitted with a TLKSR globally. 10

17 September 2008 will be a milestone in marine environment protection. Now that Panama, the 25th nation to join the Antifouling Convention of the International Maritime Organisation (IMO), has ratified in September 2007, the convention will become effective following a one-year transition period. Antifouling hull coatings containing organic tin compounds such as tributyltin (TBT), known to be harmful to sea life, will be banned as of that date.
Deadline: 1 January 2008. Notwithstanding the Antifouling Convention, applying organic tin compounds to ships sailing under the flag of an EU member state has been prohibited since 1 July 2003 under EU Regulation 782/2003 which went into effect on 10 May 2003. Existing coatings must be sealed. These stipulations will apply to all ships wishing to call at EU ports as of 1 January 2008. 15

New perspective. The AENEAS software package has been enhanced. The new tool “AENEAS Viewer” is visualizes the progress of evacuation in a 3D surrounding. “This tool offers a completely new perspective in viewing our customers results’,” says Dr Hubert Klüpfel from TraffGo HT. It is free of charge and the users are able to view the simulation results from any angle worldwide. “The Viewer gives us a comprehensible look at the process and why certain congestions are formed. Together with the customers and the authorities it enables us to find a satisfying layout for an effective evacuation concept,” says Rolf Nagel, Manager of Product Development at Flensburger Schiffbau-Gesellschaft (FSG). 13

An area where Hélimax expertise is especially sought-after is the hard-to-access regions of Ontario. A project the consulting company has been supporting since 2005 is the construction of a 101 MW wind farm for Kruger Energy Inc. in Port Alma. For Peawanuck Renewable Energy Corporation, HéliMax is currently developing terrain near Hudson Bay. Peawanuck, a remote community of 400 souls located on the southern shore of the bay, has been depending on diesel generators for electricity so far. Due to storage capacity limitations,the fuel has to be delivered in relatively small quantities at a time at regular intervals; in winter, deliveries usually arrive by plane. Wind energy would thus be an environment-friendly, cost-effective alternative. This doesn’t apply to Ontario’s remote areas. Indeed the liberalized energy market of this economically dynamic region, where generation, transfer and control of energy are in different hands, is badly in need of new capacity. The Canadian Federal Government under Prime Minister Stephan Harper therefore passed an ecoENERGY programme in early 2007 to support renewable energy sources. Provinces that have put climate protection high on their agenda – such as Québec, Ontario und British Columbia -are especially active in wind power. 64

To date, Germanischer Lloyd’s Industrial Services unit has been focused on asset and process safety, production know-how and inspections as well as evaluation of structures and safety-related components. GL’s business segment Oil and Gas provides third-party certification and inspection, independent design verification, production monitoring of components and installations as well as risk-based inspections and condition surveys of production facilities both onshore and offshore. With the complementary services offered by Advantica, the GL range of services now extends across the entire asset life cycle. Advantica’s specific strengths in safety and risk studies, asset performance optimization, asset integrity management, planning and design solutions and software products enable the new, expanded group to offer a one-stop solution for clients throughout the oil and gas sector. 49
