Oceanology International 2010 Preview (2)

This is the continuation of the Oceanology International Preview. For companies A - L, see part 1  MacArtney Underwater Technology Group MacArtney will be introducing their newest innovation in multiplexers - the NEXUS MK E electrical multiplexer, which is designed to the same high standards as the fibre optic multiplexer range with the telemetry part of the multiplexer adapted to non-fibre optic cables. Another highlight will be the demonstration of a working active heave compensation winch, the Cormac 3 Stainless Steel winch. It will demonstrate load stability during vessel movement on the sea. MacArtney will show their Focus ROTV, camera... (read more)

The Future of ECDIS

After a gap of five years, the 2nd ECDIS Conference took place in Singapore in October 2003. At first glance everything was as before: the venue of the conference, its organisers, the lecturers and companies involved, and Ð strangely enough Ð even many of the titles of the presentations. But the most important item had changed and this was the mood in which the topic was presented. Five years ago almost everybody agreed that we were about to see a great breakthrough in the ambitious IMO/IHO ECDIS venture. This time, a gloomy mood of resignation and frustration seems to have...

Motion Sensor Performance

Direct Comparison Using 2005 Common Dataset
Integral components of a swathe bathymetry system are the motion and heading sensors. The current trend is to offer a system that combines both components in one package, either as an aided inertial sensor or as two sensors linked by component software. The quality of these inertial sensors has a direct effect on the quality of the final survey. This paper compares five leading available sensors, concluding that they produce markedly differing results. Most surveyors when purchasing or specifying a particular inertial system for a project will base their decision on information generated by the manu-facturers, which often shows all... (read more)

“Developing by Leaps and Bounds”

Hydro international Interviews Shou Shunbao, Manager, Da Hua Hydrographic Surveying Company, Shangha
It may look as though Europe, the USA and Canada, followed by Australasia, dominate the hydrographic world scene. But there must also be enormous potential in the area north of the Far East: Vietnam, China, Japan, etc. In particular, the economy in China is growing fast and, with her long coastline and dependence upon shipping, China must see a considerable amount of hydrographic work. Hydro INTERNATIONAL interviewed Mr Shou Shunbao, manager with Da Hua Hydrographic Surveying Company of Shanghai, to obtain more information on hydrographic activities in the area. Shou Shunbao, born in November 1955, graduated from Nanjing College of... (read more)

Hydrographic Surveying: Where Do We Stand?

The Ever-increasing Accuracy of Mapping Surface Waters
Hydrographic surveying is highly specific and requires a suite of advanced acquisition and positioning sensors attached to a mobile survey platform as well as sophisticated software to allow the correct combination of all the data. For those in the industry, the advances over the last decade may feel more like an evolution rather than a revolution. If we look back one, two or even three decades, we can see the enormous leap that hydrographic surveying has taken. Where do we stand, and what can we expect for the near future? In this article, we will look at the present compared... (read more)

IC-ENC: Showing the Way for RENCs

International Co-operation for ENC Coverage
Producing official Electronic Navigational Charts (ENCs) is a responsibility of every coastal state. Making ENCs work together flawlessly and seamlessly on an ECDIS display requires close co-operation between Hydrographic Offices. Twenty-five countries from all continents, numbers growing, have already agreed to co-operate under the umbrella of the International Centre for ENCs (IC-ENC) to ensure high-quality and consistent data, and to release all ENCs to accredited companies providing official services to the global maritime market. Ideally such co-operation should involve all HOs in achieving worldwide ENC coverage of consistent quality: an aim that would be facilitated by forming a worldwide ENC... (read more)

The Dawn of the Digital Age

How digital visual systems lower costs and improve efficiency
Traditionally, Video Inspection surveys have been performed by ROV using analogue CCD colour cameras, with the video pictures recorded to S-VHS videotapes. This technology has served the industry well for more than twenty years but technology moves on: the world watches films on DVD, digital video movie trailers can be viewed over the internet and 3G mobile phones allow digital video clips to be viewed on the move. We are about to witness the same paradigm shift in the way we handle video information as occurred twelve years ago when CD audio replaced analogue vinyl recordings. Digital video systems offer...

GNSS: Hydrographic Perspectives (Part 2)

Developments in GNSS, Possibilities for Hydrography
Hydro International Interviews Gary Chisholm, Trimble, Paul Cross, UCL, Owen Goodman, Fugro and Peter Grognard, Septentrio<br /> <br /> When Hydro International interviewed a group of experts on developments in GNSS as related to the hydrographic profession, they responded with such enthusiasm that that we were forced by lack of space to publish the interview in two parts. Part 1, which concentrated on the new opportunities offered the surveyor by horizontal and vertical accuracy and the need for differential solutions, appeared in our October issue. We now present the second part of the interview. Can you briefly explain the possibilities/advantages... (read more)
