Businesswoman in the Middle East

Interview with Susan Murray, General Manager of the Seatronics’ Middle East office
Ms Murray joined Oceonics (the forerunner of Seatronics) in 1981. It was here that she got her first taste of business in the hydrographic Industry, specifically in the sales environment. After spending a couple of years gaining valuable experience with another equipment rental company in Aberdeen, she returned to Oceonics as Sales Manager. Between 1987 and 1996 she was the General Manager of her own equipment rental company in Aberdeen, selling this in 1996. In 2000 she decided it was time to move on and, believing herself too young to retire, agreed to take on the role of Middle East... (read more)

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)

Ocean Survey - The World Market

Over the past thirteen years Douglas-Westwood Limited has produced a series of occasional techno-economic studies of the Ocean Survey industry. This latest, The World Ocean Survey Report 2004-2008 aims to review the most significant recent developments, value markets and provide a forecast for the period 2004 to 2008. In practice, it is very difficult to precisely define the boundaries of the subject of ocean survey as for example some definitions may include survey of the major navigable waterways. Furthermore, commercial survey & positioning (S&P) contractors’ activities range into other areas, including the operation of assets in non-survey tasks, such as... (read more)

Exploring Coral Reef Sustainability

The Island of Bonaire in the Southwest Caribbean, a Marine Protected Area since 1979, has one of the most pristine coral reefs in the region. The last synoptic survey of the leeward coast was by the Dutch scientist Dr Fleur van Duyl in the 1980s and parts of the deeper reef have never been mapped. In January 2008, the US National Oceanic and Atmospheric Administration (NOAA) funded a unique expedition to Bonaire, deploying three compact Autonomous Underwater Vehicles (AUVs) carrying various oceanographic instrumentation packages and a swath bathymetry sonar.<p> The crystal-clear watersand schools of reef fish made an enchanting setting...

The Rocknes Casualty 2004

A Chartmaker’s Retrospect
The MV Rocknes (about 17,000 GRT (Gross Register Tons), draught approximately 10.5m, see Figure 1), en route from Eikefet, Norway to Emden, Germany, hit a shoal in Vatlestraumen, Norway on 19 January 2004. The vessel carried a pilot from the Norwegian Coastal Administration (NCA). Soon after the grounding the ship capsized with the loss of 18 crew. 12 crew were rescued. Norwegian Hydrographic Service (NHS) was blamed for not publishing its knowledge of a presumed new shoal in the Vatlestraumen. Three subsequent lawsuits were necessary to establish a credible explanation of the accident’s root causes. 10 years after the serious... (read more)

Heaven Descended to Earth

The Invention of the Fresnel Lens
At the dawn of the nineteenth century, France, like every other nation, regarded shipwrecks as an inevitable downside of maritime life. There were fewer than 20 lighthouses dotting the French coastline, and these were generally limited to its harbours, intended to guide ships into port. The government did not keep any records about the number of ships that went down, but the numbers were clearly in the hundreds every year. Napoleon Bonaparte formed the first national lighthouse organisation, the Commission des Phares, in 1811. This came at the peak of his imperial conquest of Europe, and his decree promised to improve... (read more)

This Is How Airborne Multibeam Lidar Coastal Mapping in Paradise is Done

Insights from the first commercial use of Fugro RAMMS
The Rapid Airborne Multibeam Mapping System, RAMMS, was developed over a period of three years before it was officially launched in the summer of 2018. Senior hydrographer Richard Goosen describes how Fugro used the system for coastal and nearshore mapping at the paradise Turks and Caicos Islands. The Rapid Airborne Multibeam Mapping System, RAMMS, was developed over a period of three years before it was officially launched in the summer of 2018. Senior hydrographer Richard Goosen describes how Fugro used the system for coastal and nearshore mapping at the paradise Turks and Caicos Islands. In July 2018, Fugro embarked on a large-scale project to map the Turks and Caicos Islands for the United Kingdom Hydrographic Office (UKHO). This landmark effort called for integrated, high-resolution bathymetric, topographic and orthoimage datasets to support nautical chart updates and coastal zone management activities. To achieve the sizeable bathymetric portion of the... (read more)

Collision at Sea

The Loss of the Coast Survey Steamer Robert J. Walker
On 20 June 1860, the iron-hulled United States Coast Survey Steamer Robert J. Walker was proceeding to New York City, its home port. The ship, under the command of Navy Lieutenant John Julius Guthrie, was returning from a successful season surveying in the Gulf of Mexico where it had been working since January. The crew would have been in high spirits anticipating seeing wives and families, sweethearts and friends the following day when the ship was scheduled to arrive at the Brooklyn Navy Yard. At 2:20 in the morning of 21 June, disaster in the form of a collision with... (read more)
