Self-installing Wind Turbines

A Different Approach
The Dutch company SPT developed a new foundation concept for offshore wind turbines in order to reduce the costs and environmental impact: a Self Installing Wind Turbine. The concept is based on a tripod with suction piles. As these foundations do not penetrate as deep as single pile structures, a different approach for survey and soil investigation techniques can be applied. Prior to the design of a wind farm, information on the seabed properties, its behaviour and the underlying geology are required. Insight into the morphology of the seabed by multi-beam (Figure 1), and side-scan sonar surveys (Figure 2) can... (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)

UKHO Acquires SevenCs

HI Interviews Dr Wyn Williams, UKHO and Gert Büttgenbach, SevenCs
More and more public institutions are involving themselves in private enterprise (see interview ‘The Public-private Dilemma’, December 2005). Is the line between public and private activities becoming blurred? The UK Hydrographic Office has just announced its aquisition of SevenCs, a German producer of ENC production tools and ECDIS.ECS systems (see this month’s Market Place). Hydro international was eager to learn of the thinking behind the move and future plans. We were fortunate, at short notice, to interview UKHO Chief Executive Dr Wyn Williams and co-founder and executive director of SevenCs, Gert Büttgenbach. The press release on the acquisition of SevenCs... (read more)

Seabed Characterisation Using Wind Noise

The acoustic reflection coefficient of the seabed can be measured from the wind-generated noise of the ocean using a vertical line array of hydrophones suspended in mid-water. Results of experiments at several sites have previously been published and an example is presented here. The effect of the seabed on acoustic propagation from a source to receptor is illustrated by means of a simple formula.<P> The formula predicts thatfor a highly reflective seabed the received acoustic power at moderate ranges could be at least four times that received from a single direct path, and higher still at long ranges. Such effects... (read more)

Following a Legacy

Hydro international Interviews Albert II, Prince of Monaco
At the invitation of Prince Albert I, the Principality of Monaco has been the headquarters of the International Hydrographic Organization since 1921. Looking at the annual reports of the International Hydrographic Bureau, the Government of the Principality has always been generous with the Organisation, providing it with beautiful premises and constant diplomatic support. Prince Albert II, Sovereign Prince of Monaco since April 2005, continues the tradition of his predecessors. Since 2001, Prince Albert is also president of the International Commission for the Scientific Exploration of the Mediterranean. He kindly accepted to be interviewed by Hydro international. You were named after... (read more)

The Arctic Field Party

It seems ironic that in the early stages of the Cold War, the United States Government sent surveyors and hydrographic engineers to the coldest reaches of the North American continent. For these men, it was truly a Cold War. From 1945 through 1953, field parties of the United States Coast and Geodetic Survey were sent to survey sea routes through the Bering, Chukchi and Beaufort Seas as well as to conduct geodetic surveys to help position Distant Early Warning system radars and help delineate the vast resources of the Alaskan Arctic. These men toiled in obscurity beneath the midnight sun... (read more)

Looking Far beyond the Horizon

Hydro International Interviews Steven Xu, CEO, Hi-Target
These are exciting times in the geomatics and hydrographic industry. Innovative solutions are being developed, integration is the main keyword and the big players are acquiring smaller companies that add a new dimension to their portfolio. Europe, Japan and North America are traditional strongholds of geomatics, but several very ambitious companies from China are doing their utmost to catch up with the frontrunners. Steven Xu, CEO of Hi-Target, was more than happy to share his thoughts and expectations with Hydro International. Read the interview here. Wim van Wegen and Joost Boers, Geomares Publishing, The Netherlands Hi-Target was established in Guangzhou,... (read more)

Paperless Navigation – Better Now Than Later

On the Way to Cost Savings and Safer Navigation
With the introduction of the amendments to SOLAS regulation V/19 making the carriage of Electronic Chart Display and Information Systems (ECDIS) under SOLAS chapter V Safety of Navigation mandatory, as proposed by NAV 54, the BIG question now is how and when to implement the ECDIS and ’Paperless Navigation’ on board vessels. Waiting until the last applicable dates may seem to be an obvious choice but obvious choice is not always the best choice. Paperless navigation has proven to save costs (eventually), enhance safety on board and attract quality manpower. Can such factors definitely offset the cost of implementation? The... (read more)

Uncovering the Mysteries of the Oceans

What is Oceanography and How to Become an Oceanographer
This article will dig into the field of Oceanography and the trends and methods developed over the past decades. Did you know that marine species compound more than 80% of the Earth’s biodiversity? Or that seaweed and other sea plants living in the ocean produce around 50% of the oxygen in the atmosphere? With this in mind, many efforts are now concentrated on studies of the ocean, such as identification of those beneficial to ocean resources and organisms that can be used as medicines for many critical ailments. Within this article, you will also get familiar with terms like biomimicry,... (read more)

Satellite Derived Bathymetry Migration

From Laboratories to Chart Production Routine
Much has been said about Satellite Derived Bathymetry (SDB), but with the exception of SHOM, which led to the introduction of a number of SDB charts into the French chart series, next to nothing has been implemented within the international hydrographic community. This article aims to update readers as SDB, thanks to new generation satellites and modelling, seeing the light after going through a thirty years’ tunnel. In 2014, detailed tests and analysis conducted by government hydrographers, cartographers and recognised satellite scientists operating for a number of projects initiated by the European Space Agency, the WWF and other stakeholders, were completed,...
