Forssea Robotics on ATOLL in Subsea Industry Gautier Dreyfus – Co-founder & CEO at Forssea Robotics, who has presented at the 4th Annual Advanced Subsea Power & Heating Cable for the Oil & Gas Industry meeting in London on Tuesday 30 of October, shared with us an overview of his company as well as the benefits that come from using ATOLL ROV. Paris-based Forssea Robotics is a subsea robotics and research and development (R&D) startup company set up in 2016 to reduce operating costs in the ROV and subsea markets. France’s Ecole Polytechnique launched Forssea as a spin-out from ROV operator […]
Fibre Optic Cable Failures vs. Power Cable Market controversy as a highlight of the 4th Annual Offshore Power Cable Engineering and Reliability Forum! “The 4th Annual Offshore Power Cable Engineering and Reliability Forum has just drawn to a close and I’m still buzzing from the presentations, audience led interactive sessions and panel sessions including the odd point of controversy from the last two days in Prague. More than 55 specialists in the power cable market descended on the Grand Majestic Hotel on the 30th and 31st January 2018 hailing from Sweden to Switzerland, UK to USA, Norway to the Netherlands […]
Remote locations of the modern offshore O&G sites are bringing the need for the reliable, efficient and cost-effective deep-water applications. Subsea cable technology has been steadily developing through the last 2 decades offering the wide range of solutions to the industry. Amongst the latest innovations is JDR’s 72 kV “wet-design” power cables and umbilicals. These designs eliminate the need for a heavy metallic radial moisture barrier as used in conventional high voltage subsea cables, therefore reducing the product load-out weight as well as the hang-off tension for deeper-water applications. For deep and ultra-deepwater, the reduction in submerged weight of […]
Nexans is well-known as a DEH (Direct Electrical Heating) system pioneer and undoubted leader. Development of the DEH system was crucial due to extending pipelines lengths so as due to the necessity of ensuring certain temperature levels and minimizing the heat losses in oil/gas flow to prevent the plug-formation. DEH system was a result of the Joint Industry Project (JIP) which was formed by Nexans, Statoil, Sintef and Technip. DEH-system has already proven itself as a great alternative for the traditional flow assurance methods including chemical treatments and pressure evacuations, providing eco-friendly pipeline heating support as well as the […]
Offshore Wind Power development has always been a subject of complex management system set up to consider all the hot spots of the projects. Conservative management models have been evolving, turning into current risk-based management approach. Experience shows that predictive models usually benefit over the reactive ones stimulating the technology to develop new practices and tools. Among all the risks accompanying the life cycle of the Offshore Wind Projects unexploded ordnance (UXO) risks should be taken into consideration at very early stage being low probability but high consequence issue. UXO risks management strategy should be based on an […]
Cable monitoring & inspection process became an inseparable part of the Offshore Oil & Gas Industry’ performance from the very beginning – any gaps in sustainability and reliability of cable network might cause serious disruptions in producer’s activity which is already set under the pressure of the recent drop in O & G prices . Cable network laid deep under water is one of the most cost-generating sectors of the offshore projects, which makes it a subject for the continuous and progressing optimization. Subsea cables are constantly exposed to variable threats so as axial compression, stress corrosion and fatigue, overheating […]
Offshorewind energy cluster is gaining bigger energy market share through the latest decade. At the same time wind farms owners continuously face numerous challenges linked to operation and maintenance. And while some of these challenges are connected to “on the water” parts of the farm and relatively approachable for the solutions application, other challenges lie deep under the water. Among these challenges, the issue of biofouling can’t be ignored. The term “biofouling” describes undesirable growth of marine organisms on immersed artificial structures. In case of the wind farms it concerns underwater cables, all the immersed parts of the substations and wind turbines. […]
Offshore and subsea Oil and Gas industry places the umbilicals as the main tool for establishing the connection between the host facility through which control is exercised, power transmitted and utilities such as injection chemicals delivered to subsea wells. Thus the umbilical technology stays a constant subject for research and improvement. While the industry is exploring new depths, it’s setting up new requirements for the umbilicals -extensive length, amended reliability and sustainability, improved dynamics. Umbilicals developers face reasonable challenges meeting mentioned requirements: fluid pressure, tube stress, hold back tensions, effect of DAF, friction, track length, crush load, heavy inner bundles, stress […]
