Excited by Automation Driven by Autonomous Vehicles

Hydro International Interviews Capt. Shep Smith
NOAA is one of the bigger organisations in the world that has surveying and charting in its portfolio. It’s an immense task as the USA has about 95,000 miles of coastline, important ports and a wide range of users – from recreational boaters to the biggest container vessels and tankers. The country also has to deal with environmental disasters like hurricanes and oil spills. NOAA is undergoing changes as the chart portfolio is ‘going digital’ and new initiatives such as using Maritime Autonomous Systems (MAS) for surveys. Hydro International interviews Capt Shep Smith, who generously gave an insight behind the scenes.

Bathymetry From Space

Global grids of synthetic bathymetry make it a simple matter to portray generalised ocean depths in all parts of the world, except the central Arctic Ocean. Derived from measurements of satellite height above the sea surface, synthetic bathymetry lacks the resolution and accuracy of acoustic soundings, plus it contains flaws that arise from measurement and computational processes. Users must therefore exercise care in the analysis and presentation of such information. In Part II of his satirical account Gulliver’s Travels into Several Remote Nations of the World, Jonathan Swift described his protagonist’s thoughts after a close-up observation of the flawed complexions...

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. Can you briefly explain your position in the hydrographic world: your experience and present position? Cullen: I have been employed by... (read more)

Sea Levels and the Coast

The oceans are a central part of the global climate system. As Roger Revelle, one of the early directors of the Scripps Institute of Oceanography, said, “The oceans exert a profound influence on mankind and indeed upon all forms of life on Earth. The oceans are inexhaustible sources of water and heat, and control the climate of many parts of the world.” He also recognised that “human beings are now carrying out a large-scale geophysical experiment of a kind that could have not have happened in the past nor be reproduced in the future”. Roger Revelle’s thoughts have even more... (read more)

Global Navigation Satellite Systems

Infrastructure Status and Developments
The concept of GNSS was first introduced by the European Space Agency (ESA), the European Commission (EC) and Eurocontrol in the early nineties. They defined requirements for a European GPS augmentation system, GNSS-1, and a full European satellite navigation system, GNSS-2, later together renamed EGNOS (European Geostationary Navigation Overlay System) and Galileo. Satellite navigation infrastructure status and developments are described here. Nowadays the term GNSS is used for the system of systems comprising GPS and GLONASS, with the later addition of Galileo. Satellite-based and ground-based augmentation systems (SBAS and GBAS) were introduced to augment GPS and GLONASS. Hydrographers were early... (read more)

Proliferation SeaSonde Coastal Current-Mapping Radars

HF interference to improve coverage performance
For several decades while coastal HF current-mapping radars were under development, they radiated rarely and only for a few weeks at a time. Now 120 commercial SeaSonde units have been sold and seventy operate continuously in permanent locations. Their numbers are presently increasing at a rate of about 35 per year and they are used for a variety of maritime purposes. Although emitting only 50 watts of power they can map currents to 200km on the lower frequencies; these signals may also travel half way around the world, thanks to overhead reflecting ionospheric layers. After all, these same layers have... (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)

'Check and double check your data before getting somebody else to check it for you’

7 Questions to Phil Payne, Survey Delivery Manager, UK Hydrographic Office
Phil Payne, survey delivery manager of the UK Hydrographic Office talks about hydrographic programmes to support blue economic growth, intentional projects and the use of lidar for charting purposes. "There will be a continued drive towards autonomy and automated processing.” Phil Payne, survey delivery manager of the UK Hydrographic Office talks about hydrographic programmes to support blue economic growth, intentional projects and the use of lidar for charting purposes. ”There will be a continued drive towards autonomy and automated processing.” Prior to his work with the UK Hydrographic Office (UKHO), Phil Payne spent 25 years in the Royal Navy as a hydrographic and meteorology specialist.

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.

WiMUST – A Fleet of AUVs for Seismic Surveys

EU-funded WiMust Project Advances a Novel Appraoch to Existing Methods
The ongoing WiMUST (Widely scalable Mobile Underwater Sonar Technology) project aims to design and test a system of cooperating autonomous underwater vehicles (AUVs) that would simplify seismic surveying and offer significant advantages over modern streamer-towing operations. Seismic surveys are a crucial part of offshore exploration, producing detailed imagery of sub-bottom rock formations that enables the location and evaluation of oil and gas deposits. Other commercial, scientific and military uses include assessments of the seabed for offshore construction, installations of renewable energy infrastructure, academic studies of the geology, civil engineering projects in shallow coastal zones, etc. Traditionally, seismic acoustic surveys are...
