Calculation Tools News

DNV GL’s Nauticus Hull software has been given a major upgrade to provide improved support for the new DNV GL rules and IACS requirements. The software covers DNV GL rules for classification of ships and IACS Common Structural Rules for Bulk Carriers and Oil Tankers with capabilities ranging from simplified rule-check and scantling calculations to advanced tools for finite element structural analysis. Geir Dugstad, Director of Classification at DNV GL – Maritime said, “With this new version we have a very efficient rule calculation tool on the market.

At a signing ceremony on June 1 at the Nor-Shipping trade fair in Norway, engines manufacturer MAN Diesel & Turbo signed a cooperation agreement with ship equipment supplier MM-Offshore. The impetus for the agreement stems from industry efforts to enhance ship performance. These have resulted in highly efficient propulsion and maneuvering systems with both now optimized – individually – essentially to perfection. He added, “A number of recent projects have already documented how beneficial such a combined optimization could be for ship designers…

The introduction of the IACS Common Structural Rules for Bulk Carriers and Oil Tankers (CSR BC & OT) makes support from advanced rule calculation tools more important than ever. The latest releases of DNV GL’s integrated calculation tools Nauticus Hull and Sesam GeniE offer designers and yards increased calculation speed and efficiency in design, CSR BC & OT rule calculations and the approval process. “We were one of the first classification societies to integrate support for the common structural rules into our tools,” says Vebjørn J. Guttormsen, Head of Section Calculation Tools at DNV GL – Maritime. “Since then, our tools have been used successfully in many newbuilding projects by yards and designers, especially in Korea, China and Japan, and the new versions build on this experience.

International classification society Bureau Veritas has dramatically slashed structural computational and verification times. The dramatic reduction in the time needed to check the structure, seakeeping and stability of new vessels and floating offshore units is being delivered through the use of a powerful 3D model which links directly to BV’s entire VeriSTAR suite of calculation tools. Philippe Donche-Gay, Executive Vice-President, Marine & Offshore Division, says, “The power…

The new Wärtsilä Steerable Thruster series (WST) is being introduced to replace the company's Modular Thruster and Compact Thruster series, while the new Wärtsilä Transverse Thruster series (WTT) is replacing the current range of transverse thrusters. The new products have been developed in response to changing market demands, requiring competitive thruster products which are more efficient and cover a wider power range. This major product development project was launched by Wärtsilä's Propulsion R&D already in 2011.

The Danish National Advanced Technology Foundation (Højteknologifonden) has invested in a project collaboration aimed to reduce older container ship energy comsumption by 10-20%. The collaborators in the project are MAN Diesel & Turbo, Maersk Line and DTU Mekanik (The Technical University of Denmark's Mechanical Technology Department). The collaboration partners explain that Increasing oil prices have resulted in the massive container ships that carry cargo to the four corners of the world having to sail at a slower speed in order to save fuel.

With funding from the German Federal Ministry of Economics and Technology and supported by "Projektträger Jülich" (PTJ) (project sponsors Jülich), over the next three years Hamburg University of Technology, Mareval AG Hamburg and the maritime engineering company HeavyLift@Sea will conduct research into the improvement of tools for the simulation of offshore crane operations. The project is named HoOK - Hochseeoperationen mit Kranen [Offshore Operations with Cranes]. The goal is…

Applied Weather Technology, Inc. today announced its BVS onboard software provides Emission Control Areas (ECAs) and calculation tools to evaluate the most cost effective voyage track. Using the latest version of BVS, captains manage their voyage track by displaying ECA zones and making them “no-go” areas. By doing this, they can see their voyage track outside and inside the ECA zones. Simply moving waypoints in BVS allows captains to visualize the impact of time in the ECA zone and compare it to the overall effect of time en route. The result is that the captain has the information to sail the optimal route. “With BVS’s ECA zone calculation tools…

At the Connecticut Maritime Association 2010 Shipping Exposition, Veson Nautical, the premier provider of Maritime Enterprise Resource Planning (Maritime-ERP) solutions and services, announced that a new module, IMOS Demurrage Management for Charterers, is available to IMOS users. IMOS Demurrage Management supports the business needs of marine demurrage specialists with tools to track and improve claims performance and limit demurrage exposure to loss. IMOS Demurrage Management, analysis and workflow tools are designed to improve response time, throughput and claim results. Real-time voyage events  trigger automated alerts to ensure that all claim and re-bill opportunities are promptly recognized, while time bar driven work processes ensure that each claim is submitted on time.
