Another Sabertooth Vehicle for Hibbard

technology for long tunnel inspection, breaking its record with a 12 km Australian run using its initial Sabertooth vehicle.The Sabertooth technology also enabled Hibbard to lead in water-filled tunnel inspection at speed and against flow – and negotiate more consecutive bends than conventional systems.In addition to its single hulled Sabertooth, Hibbard has also evaluated the double hulled Sabertooth which has led to the recent purchase and a vision of increasing their capacity to both single and double hull vehicles to fit a broader range of capability.Hibbard has deployed the double hull

Fugro Wins Project Off Dutch Coast

including state-of-the-art geotechnical drilling vessel, Fugro Scout. Deployment of Fugro’s innovative SEACALF MkIV system for seabed cone penetration testing will enhance operational safety as its coiled rod requires no manual handling. The system is also much less weather sensitive than conventional systems, increasing productivity by avoiding downtime.With a total capacity of 1400 MW, the Hollandse Kust (west) Wind Farm Zone lies in the coastal waters of the province of Zuid-Holland, 51 kilometers off the west coast of the Netherlands

Seafloor Crawlers: New Robotic Tools for Challenging Missions

. With a 16-km underwater range (32+ km surface), it can survey whole beaches in a single day. The modularity of the Sea Ox allows it to be hand carried through sensitive beach areas and can be launched and recovered by a single person from shore; reducing the cost of surveys to a fraction of conventional systems where the logistical costs can out-weigh the actual operation. Some recent applications have demonstrated this potential.UXO RemediationThe Sea Ox is a man-portable bottom mobility platform for UXO investigations in the transition, surf and very-shallow water regions.

Schlumberger Introduces MEMS Gyro Surveying Service

gyro-surveying while-drilling tool that increases drilling efficiency and reliability while reducing drilling risks.As the first application of microelectromechanical system (MEMS) technology for gyro surveying while drilling in the oilfield, the GyroSphere sensor performs gyro surveys faster than conventional systems and avoids the need for recalibration between runs. Solid-state technology enables the GyroSphere sensor to withstand the downhole shock and vibration that occur during drilling beyond the limits of current gyro technologies. Additionally, the GyroSphere service can reduce gyro survey uncertainty

NATO Science Mission Employs ‘Double Muscle’

behaviors. CAT tests perfectly fit in the GAMEX ‘17 main goal, i.e. advance methods for using robotics in mine countermeasures (MCM), in a diverse and challenging environment. Being part of a live exercise, this experimentation also makes it possible to benchmark robotic mine-hunting with conventional systems, thus facilitating the future technological transfer to operations. Interoperability and multi-vehicle collaboration is emphasized both to accelerate the MCM timeline (detection, classification and identification) and improve autonomous localization capabilities through underwater communications

Forum Delivers Its Largest Subsea PLR Systems to North Africa

of work for the project, which included the full design, manufacture and testing of the PLRs, underlines the fully integrated system we can offer from concept through to delivery.” In addition to their size and weight, Forum’s PLRs have other additional capabilities compared with conventional systems because they are also equipped with a remotely operated vehicle (ROV) readable subsea flow meter, a ROV operable choke valve for discharge throttling to control the pigging velocity.  Forum also developed and manufactured a landing interface from the PLR’s to the pipeline end terminator

Offshore Tests Prove Thunderstorm Detector’s Efficiency

the reporting of this significant cloud type.    The equipment is also virtually immune to all forms of man-made radio-frequency interference which minimizes the likelihood of false alarms. This combined with the high sensitivity and ability to detect over twice as many flashes as conventional systems makes it ideal for reliable thunderstorm detection

Ecosse Subsea Systems Prepares to Shake Up Pipelay Sector

, mobility and reduced cost, both in terms of the pipelay system itself and also associated vessel costs. The PREP system takes advantage of the underutilised elastic properties of steel pipe to be able to lay pipe from smaller vessels and the huge fleeting tower that is the dominant feature in conventional systems is not required. PREP’s flexibility addresses one of the major barriers to entry into the conventional pipelay market - capital investment in suitable pipelay vessels, spool bases and global infrastructure. Ecosse Subsea Systems managing director, Mike Wilson, said: “PREP
