Developed by Bibby HydroMap, the innovative d’ROP® system has the potential to revolutionise productivity in shallow water survey and inspection applications.

d’ROP® is a dynamic Remotely Operated Survey Platform that borrows and combines technology and operating principles from existing ROVs, ROTVs and systems from the modern day dredging industry. Addressing many of the inherent limitations of compact free-flying ROVs and seabed crawler systems, the d’ROP is ideally suited to precision tracking operations in dynamic coastal environments.

Station-Keeping Ability

The d'ROP is deployed vertically beneath the support vessel, deriving vertical position from a heave-compensated winch and combined LARS, with the on-board thrusters maintaining heading and fine adjustments to the lateral position. Maintaining a fixed heading and altitude in relation to a survey line, cable or pipeline provides exceptional line-keeping ability in comparison to traditional mid-size ROV systems. Providing significantly more thrust than an equivalent-sized ROV, the d’ROP's ability to hold station allows it to remain stationary, operate at slow speed for depth of burial surveying, or track at up to 4 knots for acoustic survey.

Coastal Remote Survey Solution

For remote shallow water cable and pipeline survey,  the d’ROP excels in providing accurate depth of burial data in areas where compact ROVs struggle with the environmental conditions and work-class ROVs add significant expense. Designed for operation from our 27.5m coastal survey vessel Bibby Athena, the compact system is uniquely designed to operate effectively from 5.0m to 150m water depth.

  

Variety of Applications

Whilst the d’ROP was designed primarily for precision tracking of buried cables and pipelines in coastal environments, using proven technology and off-the-shelf components the d’ROP can accept multiple sensors simultaneously

The beauty of this system is that it is assembled from proven components and has the flexibility to support virtually any survey sensor. It can be considered as an extension of the survey vessel as it allows us to deploy our sensors where they are needed for maximum effectiveness rather than further and further away from the point of interest as water depth increases or environmental conditions deteriorate.”

Bibby HydroMap Managing Director Andy McLeay

The d’ROP has been designed to offer a remotely operated survey platform capable of operating effectively and cost efficiently in dynamic marine environments, whilst accommodating various survey sensors, including the PanGeo SBI. Originally designed for operation from predominantly work-class ROVs, the PanGeo SBI provides a real-time 3D grid view of the sub seabed, accurately imaging buried pipelines, cables and other buried objects. One key benefit of the PanGeo system over traditional pulse-induction technology is that the cable can remain in service throughout survey operations, resulting in a significant cost-saving for the operator.

 

Designed to Partner Bibby Athena

The system has been designed initially for operation from the company’s newly launched custom-build survey vessel Bibby Athena. Deployed vertically through the vessel’s moonpool, the system relies upon the support vessel for forward propulsion, a bespoke heave-compensated umbilical winch and combined LARS for its vertical control with the on-board thrusters maintaining heading and fine adjustments to the lateral position. 

Inherent Simplicity

“The system is effectively a compact high powered work class ROV platform but with all the expensive and complicated bits that we don’t need for our survey tasks stripped off; no vertical thrusters, simplified ‘hands-off’ deployment and close to fully automated operation."
