New ABB data recorder A


BB’s new RVG200 paperless data recorder incorporates a number of advanced features


giving operators slick, easy and secure access to process data. A key feature is the RVG200’s use of touchscreen


technology. By using the device’s intuitive icon- based menus or ‘swiping’ through the screens, operators can rapidly find the data they need. This data can be viewed in a variety of formats, including individual or grouped data in chart, bar graph or digital indicator displays. Up to 24 universal analog inputs enable direct


connection of mA, mV, TC, RTD, voltage and digital signals. Coupled with a 125mS sample rate and 500V galvanic channel to channel isolation, these inputs deliver reliable, highly accurate, data from connected process instruments.

Software update efficiently calculates electrical quantities in real time


current and voltage that need to be measured and evaluated in various industries. Millions of measurement data may need to be acquired, stored and visualized every second during efficiency and safety tests in the aviation sector or while evaluating electric motors in the automotive sector. Similar measurements are also needed during the monitoring of generators, motors or inverters. Users can now implement real time calculations per channel


H


using several logical calculation channels. Calculations such as the real RMS value, min/max/mean values, peak-to-peak, area and energy can now be easily undertaken.

Maple helps engineers design propulsion systems for some of the world’s biggest ships


MAN Diesel & Turbo, headquartered in Germany, is at the forefront of the


quest for improved performance in marine propulsion systems. MAN designs and builds marine propulsion systems from 4 to 40MW in size, with controllable pitch propellers (CPP) of up to 11m in diameter and even larger for fixed pitch propellers. The world-leading technical computing software, Maple, from Maplesoft is playing an important role in keeping the propellers efficient and dependable, thus keeping costs down.


Mads Hvoldal is a mechanical engineer at the MAN Diesel & Turbo


Propulsion Competence Centre division in Frederikshavn, Denmark. He works for the team that designs the mechanical and hydraulic control systems used to vary propeller pitch. “We produce a range of standard designs but it is the nature of the industry that many propulsion systems are engineered for specific vessels,” he explains. During peaks in demand for new vessels, development of hundreds of different designs per year is common. They need a software system that is robust and flexible.


“I had quite a lot of experience using Maple in hydraulic systems design in


manufactured goods from Asia or car carriers shifting vehicles from factories in Europe, the global maritime industry moves around 32 trillion tonne-miles of cargo every year, four times more than it did at the end of the 1960s.


S To deliver this dramatic increase in cargo, the industry has had to change


drastically over the past few decades. Vessels have become larger and more efficient as shipping companies work strenuously to keep costs down in the face of rising and ever more volatile fuel costs. For marine engineers, that means constant pressure to refine the performance and reliability of vessels and their systems. Nowhere is that pressure felt more acutely than in the most fundamental component of any modern powered vessel: its propellers.

hips keep the global economy moving. Whether they are ultra large crude carriers transporting oil from the Middle East, container vessels transferring


a previous role,” he explains. “So I could see its potential benefits in our current work.” The critical advantage of Maple, he notes, is that the engineers can put the design equations in their original form right into the system. “That makes Maple faster to use, with reduced need to check and debug the code.”


MAN Diesel & Turbo, Propulsion Competence Center, Frederikshavn, has


been using Maple for around six months and the power, speed and efficiency of the system has convinced its engineers that there is potential to expand their use considerably in the future. “So far, Maple has replaced our previous system for design calculations,” concludes Hvoldal, “But we are now exploring the feasibility of building standard models to simplify and automate the process further, and of automating the links between our initial calculations and the detailed part models in the 3D CAD system.”
