Advances in High-speed Underwater Remote Vehicles for Subsea Pipeline Inspection

The Benefits and Challenges of the Technological Revolution in the Pipeline Survey Industry
The pipeline survey industry has undergone a technological revolution in the past couple of years, and the consequential benefits and challenges are only just beginning to be fully realized. The cost efficiency of subsea operations has been one of the key focus areas of the offshore energy industry in recent years. This focus, combined with increased growth in the amount of subsea infrastructure now in-situ on the seafloor, has seen a rising need for innovative approaches to subsea asset inspection. These solutions need to be cost-efficient, maintain data quality, and be able to provide a platform that supports future technologies.... (read more)

Resolutions of the IHO

The year 2019 sees the centenary of the first Hydrographic Conference which took place in London in the summer of 1919. Only one year after the end of the First World War, representatives from 26 countries met in London at Trinity House to discuss and agree on future technical cooperation in hydrography. The report of the proceedings starts with the following statement: 'The experiences of the war in special relation to hydrographic matters showed most clearly the enormous importance of the possession of accurate charts and hydrographic information generally, and the very grave disadvantage attendant on their no-possession; and also...

Depth of Burial – Galloper Offshore Wind Farm

Galloper Offshore Wind Farm is a 353MW wind farm project located 30km off the coast of Suffolk, UK. It is now in full operation and each year will generate enough green electricity to power the equivalent of more than 380,000 British homes. The construction of the wind farm created almost 700 UK jobs and its operation has created around 90 direct and indirect long-term jobs in the local area. A 60-strong team will operate and maintain the wind farm day-to-day from a base under construction in Harwich International Port. There are 56 wind turbine generators (WTGs) located in water depths... (read more)

Game-changing Sensor and AI System for Plymouth Sound

M Subs has installed a ‘game-changing’ sensor system with connected artificial intelligence (AI) and machine-learning technology around Plymouth Sound, UK, as part of the vision to turn the city into a centre of excellence in maritime autonomy and unmanned vehicles. The Plymouth-based company will operate a secure network of cameras, radars, and other sensors which will provide situational awareness and communications with the unmanned vehicles operating out of the city’s harbour. The system will also provide the command & control of unmanned vehicles using the nearby ranges at sea.  Data from the network is being collected and analysed by machine... (read more)

The Study of Mapping the Seafloor

What is the Difference Between a Bathymetry Chart and a Hydrographic Chart?
This article will immerse you into the deep water of bathymetry. It explains in detail what a bathymetry map is, what it shows, what methods we use to collect the bathymetry data and, last but not least, how to create a good-quality bathymetry map. It will also cover the difference between a bathymetry chart and a hydrographic chart and the techniques our ancestors used in the past to collect and record depths. What is Bathymetry? Bathymetry is the study of mapping the seafloor. Bathymetric maps represent the ocean (sea) depth as a function of geographical coordinates, just as topographic maps represent... (read more)
