FUGRO PERFORMS OIL & GAS INDUSTRY’S LARGEST AUV SURVEY The largest AUV (Autonomous Underwater Vehicle) survey in the oil and gas industry is a core element of two contracts awarded to Fugro that also include metocean measurements and geohazard consultancy services for Eni East Africa. The data is being acquired for the Area 4 Rovuma basin development offshore northern Mozambique. The challenging AUV survey is the largest ever commissioned and one of the first in this new and remote frontier area off the coast of East Africa. Fugro is providing hull-mounted reconnaissance and AUV detailed data from the development area. The data will aid the design of subsea facilities.

piezocone penetration system, in addition to the Echo Surveyor III AUV. Meteorological and oceanographic measurements are collected using mooring buoys located in water depths ranging from 20 to 1,800 metres. To assist in the routing of the 60-kilometre export pipeline, Fugro completed a regional and local geohazard assessment, including data processing and reporting, from its offices in Europe and Asia.

Covering approximately 1,440 square kilometres, the survey area stretches from the nearshore to deepwater (depths greater than 2,700 metres). The work is being carried out using one of Fugro’s newest survey vessels, the state-of-the-art MV Fugro Equator, which is equipped with hull-mounted multibeam echosounder, sub-bottom profiler, piston gravity corer and

Hardide Coatings unveil groundbreaking new technology for TSP diamonds at Offshore Europe 2013 Hardide Coatings has developed an innovative coating to extend the life and improve the performance of drilling tools operating in extremely abrasive environments. This is the first successful high performance coating for TSP (thermally stable polycrystalline) diamonds which can withstand the higher temperatures associated with TSP brazing, extreme loads and aggressive media. This will enable a new generation of diamond-based hardfacing materials to be deployed in extremely abrasive wear and erosive conditions such as horizontal and directional drilling, as well as fracking. Improved tool performance will enhance the viability of more challenging or marginal oil and gas reserves. Hardide Coatings CEO Philip Kirkham said: “Drilling activity is taking place in deeper and more demanding conditions than ever before and tools need protection from extreme abrasive wear and erosion that current hardfacing materials can no longer provide.  Some critical drill string components need replacement after every drilling programme, so the new coating application will reduce expensive maintenance and down time costs of drilling projects. This will in turn boost the economics of smaller and more mature oil and gas fields, such as those in the North Sea.”

The coating was developed in the company’s Oxfordshire manufacturing facility following several years of fundamental research. The production process was developed with the support of a Technology Strategy Board (TSB) ‘Smart’ grant for up to £250,000 which was awarded in January 2013. The technology is covered by new UK and international patent applications. Hardide Coatings has signed a mutually exclusive five-year supply agreement with hardfacing specialists Cutting & Wear Resistant Developments Limited of Sheffield for its use in oil and gas applications.

Diamonds are notoriously difficult to attach and are prone to oxidation and graphitization, limiting their hardfacing use to date. Previous attempts to solve these problems have been unsuccessful due to the porosity of other coatings and their weak adhesion to the diamonds. Hardide-D overcame these hurdles with its pore-free tungsten carbide based adhesive and

protective coating which chemically bonds to diamond and has good wettability with brazing alloys.
