1997-2007: A Decade of Developments in Hydrography

We all know what is the oldest profession in the world. The second oldest is probably that of land surveyor: Adam undoubtedly wanted to stake out the boundaries of paradise in order to know what was and was not his. Paradise, or the Garden of Eden, was to be found in the land of the Euphrates and Tigris, where these two rivers converge at the town of Qurna in the present Shatt al Arab. And apart from his topographical activities Adam must also have made some hydrographic observations, probably just using a stick cut from a local fruit tree! After... (read more)

Low-budget Hydrography

Opinions from differing backgrounds
Low-budget Hydrography is the theme of this issue. Realising that different players in hydrography will have differing opinions on various aspects of low-budget hydrography and interested in exploring these divergent views on your behalf, HI asked representatives from various camps for their opinions on some leading questions. The representatives interviewed are: Jeffrey F. Marlow, Survey Technician, US Army Corps of Engineers CDR Guy Noll, Commanding Officer, NOAA Ship RAINIER LTCDR Richard Cullen, Staff Officer Quality Control AHS Questions: 1.

Improving Overall Resolution of Bathymetric Survey

Integrated Use of Multi-beam Echo Sounder and Towed Interferometric Sonar
Designing offshore engineering facilities requires large amounts of information. To acquire it, suites of engineering and geophysical surveys are run, which as a rule include such techniques of seabed and sub-bottom investigation as seismic profiling, acoustic, magnetic and bathymetric surveys. Obtaining accurate and detailed seabed bathymetry is extremely important because the quality of other surveys depends on the quality of the bathymetry. One of the most accurate and cost-effective ways to acquire high-resolution bathymetric data is the use of shipborne bathymetric systems such as multi-beam echo sounders (MBES) or interferometers. The drawback of this method is that the resolution of... (read more)

Fugro's CEO: “Working for a Safer and More Sustainable World”

Interview with Mark Heine
Mark Heine is chairman of the board and CEO of Fugro, with the headquarters in the Netherlands. Fugro is the leading and largest specialised survey company in the world, serving the full lifecycle of assets, and calls itself a Geo-data specialist. For the avid mountaineer Heine, challenges are never too high to take on, not even heading up a multinational in transition, from a company largely dependent on the oil and gas industry to one that wants to co-create a sustainable and liveable world. We talked to Mark Heine about leadership style, strategies for finding new employees, and Seabed 2030. About this ambitious project, Heine says ‘Commercial companies need to work together with NGOs and academia to make this happen.’ Mark Heine is chairman of the board and CEO of Fugro, which is headquartered in the Netherlands. Fugro is among the leading and largest specialized survey companies in the world, serving the full lifecycle of assets, and describes itself as a geodata specialist.

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...

Surveying and Dredging in the Middle East

Interview with Charles Martin, Martin Mid East LLC, UAE
Charles Martin was born in Cape Town and schooled at Bishops, where he played moderate rugby, bad cricket and was a reluctant member of the choir for a few years. After a year compulsory internment in the South African Navy, he obtained a Civil Engineering Diploma and commenced his professional career by blasting away a large portion of Ben Schoeman Dock for Christiani Ham. He worked for Ham Dredging for eight years and National Marine Dredging Company in Abu Dhabi for twelve years before starting his own company in the United Arab Emirates (UAE). What is the history behind Martin... (read more)

Minimising Offshore Survey Product Liability

In this article, offshore survey products are meant in the broadest sense. Not just survey, navigation and positioning, but the purpose or project that the dependent results are used for. No work in the offshore industry can proceed efficiently without good positioning data and survey information. From the initial 2D and eventual 3D surveys, through to the commissioning of the offshore installation and pipelines, offshore survey is the link between the various pieces of the complex puzzle. In this article, offshore survey products are meant in the broadest sense. Not just survey, navigation and positioning, but the purpose or project... (read more)

‘Killer’ AUV Sonar System

In January 2001, C&C Technologies (C&C), a company based in Lafayette (Louisiana, USA), introduced the first commercially successful autonomous underwater vehicle (AUV) to the offshore industry. The AUV’s survey sensor suite, which included an EdgeTech side-scan sonar and sub-bottom profiler, performed well in the Gulf of Mexico and Brazilian offshore environments. However, West Africa proved more challenging – particularly for the sub-bottom profiler. C&C soon began searching for alternative technologies to provide better sub-bottom profiler penetration and higher resolution side-scan sonar imaging.Jim Chance, C&C Technologies (USA) Art Kleiner, EdgeTech (USA)<P> Narrator: Fast forward to the early autumn of 2004… C&C...

3D Sonar in Object Detection

Intuitive real-time imaging for sub-sea visualisation and classification
Sonar is well accepted as an option for detection and visualisation of underwater objects. Side-scan and sector-scanning sonar have traditionally been used by surveyors but whilst they produce excellent images, these are often difficult to interpret accurately. This article describes new developments in 3D-sonar and their advantages and use in emerging underwater disciplines. Classic applications for object-detection are many and varied, ranging from looking for items such as wreckage, debris, lost items and so forth to defence applications, seeking out threats such as mines. Increasingly, though, object detection has been expanded to include obstacle avoidance for both surface and submersible... (read more)
