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)

Ocean Business 2013 Preview

More Variety at an Expanded Trade Show
Southampton, in the south of the UK’s Hampshire region, will be buzzing from 9 to 11 April 2013 as hydrographic, oceanographic and offshore professionals gather for an even bigger edition of Ocean Business. The organisers expect the 300 exhibitors to welcome 4,000 visitors and delegates to the National Oceanographic Centre grounds and inform them about the latest technologies. Hydro International invited exhibitors to give their preview, which we have published on these pages to give you a taste of what’s on offer during the event. 3D Laser Mapping 3D Laser Mapping is a ­world-leading provider of laser scanning technology.

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)

Geomares: Quality is Our Motto

Hydro International Interviews Durk Haarsma and Meine van der Bijl
Geomares Publishing is the new media company behind Hydro international, which in October took over ownership from the magazine’s previous publisher of almost ten years, Reed Business Geo. Publishing director of Geomares Durk Haarsma has strong in-house brands, dynamic publishing concepts for the future and a dedicated team who will keep working to deliver quality in every possible way. Could you outline your reasons for buying Hydro international and establishing Geomares Publishing? I have been in post as publisher of Hydro international now for five years and have a strong belief in Hydro international as a flagship brand. Together with... (read more)

Impact of Wastewater from Fukushima Nuclear Power Station

On the Oceanographic Environment
The Great East Japan Earthquake and Tsunami of 11 March 2011 measuring 9.0 on the Richter scale caused the meltdown and melt through of three reactors at Fukushima No.1 Nuclear Power Station (NPS). This resulted in a hydrogen gas explosion followed by the serious contamination of air, land and water over a 100-kilometre radius of NPS, including the Tokyo area. Air contamination is decreasing and is concentrated in a limited area. Land contamination has also decreased through decontamination processes. However, despite all the efforts by Tokyo Electric Power Company (TEPCO) and the Japanese government, water contamination in surface and ground... (read more)

Surface Imaging Capabilities on Marine Hydrographic Vessels

In a combined effort of the National Oceanic and Atmospheric Administration and private industry (Applanix and Riegl), two different but complimentary technologies were tested in the marine survey field to find a more efficient, higher-accuracy and safer alternative for traditional shoreline verification methods. This article describes the tests and the encouraging good results with this videogrammetry and laser scanning technology.<P> Vessel-based shoreline verification is a laborious, exacting and often dangerous element of nautical charting. During this process, a boat is deployed into the near-shore region to verify shoreline information extracted from aerial photogrammetry. Near-shore features such as piers, rocks, islets...

Quality ENC Production for HOs

The challenges facing the contractor
Hydrographic Offices (HOs) all over the world are going digital in their production environment. New shipboard equipment and improved display techniques embrace all the latest technologies in the interests of ensuring the Safety of Life at Sea (SOLAS). HOs increasingly seek to produce and distribute ENCs to standards specified in IHO Special Publication S57 (edition 3.1). The production and validation of ENC datasets to achieve these stringent quality requirements are outlined here. The International Maritime Organization (IMO) has amended SOLAS articles relating to carriage requirements for the use of ECDIS in certain types of vessels. When production is outsourced manufacturers... (read more)

Use and Exchange of Data

Hydro international interviews Admiral Alexandros Maratos, IHO president and chair S-44 Working Grou
In the early days the discipline of hydrography was meant to contribute to safe shipping. The International Hydrographic Organisation (IHO) paid due attention to the quality of hydrographic surveying and nautical charts, resulting in Special Publication Nr. 44, IHO Standards for Hydrographic Surveys (S-44). Over recent decades we have seen an extension of hydrography into other activities and adjacent disciplines such as resource development, coastal zone management, environment monitoring and so on. We have also seen the emergence of new technologies, new equipment and, last but not least, an enormous increase in data-handling capacity and speed. What role is the... (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)
