Sperre, Norway, is developing a new ROV concept (H-ROV) that is expected to make remotely controlled underwater operations more efficient. The concept distinguishes from ordinary ROVs is that its thrusters can swivel round their own axes to provide optimal driving power in the direction of travel as well as compensate efficiently for current and cable drag. This offers an improvement in performance of anything from 30 to 50% compared to all conventional ROVs currently in production. High Efficiency It means that the H-ROV will be particularly suitable for subsea dynamic positioning and autotraction operations. The buoyancy element with its thruster(s) will... (read more)

Thinking ROV

Engineers at Saab Seaeye, UK, have created a new development in ROV architecture, ‘The Intelligent Control of Nodes’ (ICON). The concept allows each device within the ROV to think for itself and talk remotely to operators and engineers through a gateway into the heart of the vehicle. It gives users remote access to diagnostics, software upgrades and system inventory directly on board the ROV, via an enabled web interface, from anywhere in the world. ICON makes this possible by enabling each microprocessor (node) to operate as a sensor and report its unique status to the central control system.... (read more)

Versatile ROV

Mariner Underwater Electronics has launched its newest electric powered ROV, the Ippodamus. It has a depth rating of 800 metres which can be increased considerably for custom-made orders. It has been designed to be used for professional inspection and survey operations (observation, inspection, tunnel penetration etc). The Ippodamus can carry sensors as well as small manipulators, making the vehicle a very useful tool in the hands of experienced and professional operators. It has a high resolution colour camera with internal green laser and a video overlay system. (read more)

ROV System for DBB

MacArtney has delivered a powerful and versatile Sperre SUB-fighter 7500 ROV system for DBB ROV Services A/S, a Danish ROV contractor for offshore drill support, inspection, survey and support in connection with installation of offshore wind turbines. The new ROV is bound to join DBB's modern fleet of underwater vehicles and is the fourth Sperre SUB-fighter system in operation for DBB ROV Services. Besides work performed on offshore drilling rigs, the SUB-fighter ROVs are also engaged in supporting the other two DBB companies - in particular on the offshore wind turbine market. Here, this type of ROV has become one... (read more)

ROV DP Capabilities Demonstrated

A recent trials partnership between Sonardyne International, UK, and USA-headquartered Oceaneering International has resulted in the development of a Fly-By-Wire (FBW) system for ROV control in any water depth, allowing the vehicle to hold station indefinitely and navigate to real-world coordinates automatically. A Sonardyne SPRINT system was installed on one of Oceaneering’s Maxximum ROVs and integrated with a Sonardyne Ranger 2 Ultra Short Baseline (USBL) system for acoustic aiding of the Inertial Navigation System (INS). The trials took place in the Gulf of Mexico in water depths of 3,057 metres (10,030 ft) and results showed that continuous hovering of the... (read more)
