IENCs in Flanders

Inland Electronic Navigational Charts Produced by Flemish Hydrography
Safety of navigation on inland waterways is as important as in maritime waters. To guarantee this, Electronic Navigational Charts (ENCs) have now been produced for several years. As inland waterways have specific features and regulations different from the maritime area, the use of ENCs is not sufficient. International standards have been developed specifically for Inland ENCs, which contain chart information required for safe navigation on inland waterways and in mixed traffic zones. These navigational charts are extremely important as they cover not only the maritime navigation zone, but also the adjacent inland waterways in Flanders which have not been mapped... (read more)

Offshore Wind Farm Developments and Scouring Effects

One of the chief risks for offshore wind farm developments is that associated withscouraround the pile bases and along the length of the cable which carries power between monopiles and to the shore. Consideration of the scour risk early in a project can provide a basis for structural designs to be modified, and for the assessment of appropriate preventive (as opposed to remedial) measures. Underpinning and running concurrently with this planning stage is the collection of information and data inputs relevant to scour risk assessment.<P> The Marine Renewables Energy Sector is an emerging force in energy provision globally and recent...

Large of Spirit

A Great Woman Explorer: Louise A. Boyd
Sprinkled throughout the world’s oceans are thousands of named seafloor features. Many of the major features have received names that associate them with some other geographic feature such as Mid-Atlantic Ridge, East Pacific Rise, or Aleutian Trench. Many of the smaller features have received names commemorating scientists, explorers, bathymetrists, hydrographers, research or survey vessels, and even crew members of those vessels. Of the names of these lesser features, hundreds are named for men who made contributions to knowledge of the sea. However, a review of both the official names of the IHO GEBCO Subcommittee on Undersea Feature Names (SCUFN) and... (read more)

Unravelling the Mysteries of Venice

Use of side-scan sonar in underwater studies
The Venice Lagoon has been inhabited for over 1,300 years and the art and architecture of its city has been the subject of countless books and academic studies. Yet, despite this continuous scrutiny, virtually nothing has been known about the world beneath the surface of the lagoon. For centuries the hydraulic processes that fill and empty the 640sq km of the lagoon daily and the landscape of the seabed have been ignored or taken for granted. The threat created by rising sea levels has finally concentrated minds on finding a way of protecting the city’s treasures. Plans are being laid... (read more)

The New Role of Hydrography in the 21st Century

Evolving from Charts to Geospatial Data
Traditionally, hydrographic data was used mainly for nautical charts. Hydrographic surveys are costly, and data should be used beyond navigation. Some have developed centralised hydrographic databases, but their only purpose is to produce charts. Hydrographic data should be used for other purposes too. Hydrographic data is the foundation for building a maritime data management system, in the framework of a Marine Spatial Data Infrastructure for broader use. Visionary organisations are already evolving their traditional roles and jumping onto the ‘Big Data’ ship and connecting to the World through web services. The use of Hydrographic data is evolving for good. When... (read more)

Different Approach to Surveying Antarctica

Operation Rock Bottom
Navigation data is poorly available in Antarctica. If navigational data is available it often dates back to the early 1900s with many lead line surveys. An initiative was undertaken by Stephen Wilkins of Xplore Expeditions to collect bathymetry with a multi-beam survey system making use of the sailing vessel Xplore. Together with Yoann Boulaire from SHOM, France and Fernando Landeta, hydrographic technician from Skyring Marine Chile, an IHO qualified survey was performed in Antarctica on an expedition sailing yacht. As all mariners navigating in Antarctica know , one must use a combination of all available means to enable safe travel... (read more)

Charting Aspects of the ­Volvo Ocean Race Stranding

Facts and Findings from the Accident
During Leg 2 of the Volvo Ocean Race from Cape Town to Abu Dhabi, Team Vestas Wind ran aground on the night of 29 November 2014 on the Cargados Carajos Shoals. The shoals were shown on the portion of the electronic chart displayed onboard, but only as a blue patch enclosed by a 200m isobath with scattered soundings - the shoalest of which the navigator reported to be 40m. The fact that the feature comprised low lying islands with a fringing drying reef is only apparent when zooming in sufficiently on the Electronic Chart System (ECS). What are the factors that...

Monitoring Marine Pollution

Detecting Offenders by Satellite in the Eastern Black Sea
An increase in marine traffic has recently been registered in the Black Sea, which is often accompanied by illegal oily water dumps, leaks during loading/off-loading operations and a higher risk of accidents. One of the primary tasks of ScanEx Research and Development Center is the operational satellite-based monitoring for real-time detection of oil spills and their sources. Repeat offenders of waste dumping and sources of pollution have been confidently identified, encouraging others to adopt a more responsible attitude towards the marine environment. View Larger Map According to statistics, transportation is the main source of world ocean pollution. This is also... (read more)

The Making of RV 'Kronprins Haakon'

New Norwegian Ice-breaking Research Vessel
Norway is a maritime country with a very long coastline, plus it is very much a polar nation with 80% of its sea territory and 45% of its land mass north of the Arctic circle. It is the only country with territorial claims both in the Arctic and the Antarctic. In spite of this, Norway has not had a purpose-built polar research vessel since Roald Amundsen’s 'Maud' (1917), having instead relied on converted commercial vessels for such purposes. That has all changed, however, now that 'Kronprins Haakon' has come into service. This article provides insight into the making of this new multi-purpose research vessel.... (read more)

Autonomous Underwater Vehicles

A View of the Autonomous Underwater Vehicle Market in 2016
This last year has seen an increase in Autonomous Underwater Vehicle (AUV) sales and prospects for new sales. The lower than usual oil price may be responsible for much of that growth. Faced with operating in an increasingly harsh market where cost efficiencies can be the difference between success or failure for a business, Oil and Gas companies have had to look for ways to operate profitably. This often means a fairly radical restructure of their business and operations. Survey class AUVs offer a level of technical and operational maturity at a price point that encourages their use by oil... (read more)
