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)

Resuming New-Zealand Charting After World War II

By an Old Hydrographer
After World War II, ship owners pressured the New Zealand Government to resume charting of coastal waters by the Royal Navy. Ships were now larger and most charts were a hundred years old. The Government approached Britain, which declined but kindly offered assistance to set up a new hydrographic service. The New Zealand Government and the Navy Board agreed that surveys must be resumed and that the Navy should undertake them. Here there were competent officers to train as hydrographic surveyors, a disciplined organisation and a large enough crew to be able to handle the ship, six boats and two... (read more)

Pathfinder

An Incident at Guadalcanal
In the Second World War, the Pacific was poorly charted, and the Navy would require the services of a cadre of hydrographers to rapidly survey areas of tactical and strategic interest. Officers of the US Coast and Geodetic Survey provided the nucleus of that cadre and served from the Solomon Islands north to the Aleutian Islands. They served on Coast and Geodetic Survey Ships, including the brand newPathfinderand even the USSRocky Mount- vice admiral Richmond Kelly Turner’s amphibious command ship. Of the survey ships, the most illustrious of all was thePathfinder,of which it was said, “The road to Tokyo was... (read more)

The Alchemy of the Sea

The Search for the Young Experts to Plug the Increasing Skills Gap
Recruitment and retention issues due to effects of the boom and bust of the hydrocarbon industry are still rocking the profession. The author suggests that the dawn of carbon-neutral energy generation will greatly benefit offshore survey. A fresh re-envisioning of the profession and those that it serves could produce a substantial rise in recruitment. As I walk my dog on a very windy Norfolk beach and look out at the North Sea I am only too aware that the wealth and prosperity these waters have brought to the United Kingdom in the last three decades is now coming to an...

Measuring Potential Acoustic Impact of Marine Renewables Development

Man-made Sound and Marine Life
Over the past decade the United Kingdom has seen a significant increase in the number of marine-based construction projects - led principally by the offshore-renewables sector. The construction and operation of an offshore development is likely to involve tasks that generate underwater noise. Such tasks may include hammering foundation piles into the subsea sediments, drilling foundation sockets into the basement rock, increased shipping for support activities and, of course, the noise generated by each and all of the turbines. As a result of these activities, there has been an increasing awareness that the man-made noise thus generated has the potential... (read more)

Challenger: the Life of a Survey Ship

This year marks the 50th anniversary of the publication
With this publication, the author – George Stephen Ritchie, founder and first editor of this column – marked himself as a noted maritime historian and, particularly, a historian of the art and science of hydrographic surveying. Admiral, then Captain Ritchie had been the next-to-last skipper of the second ship of the name Challenger and, following its decommissioning, wrote this biography of a survey ship. Some of the most lyrical passages from this work describe the period during his command. As a tribute to Admiral Ritchie and his service to our profession and the science of the sea, it is well...
