The Cougar-XTi is a deep water version of the compact, highly flexible and very powerful Cougar-XT. Apart from all the proven benefits of the Cougar-XT, such as a wide range of quick-change tooling skids, the XTi vehicle features also the iCON system, which allows identification of any malfunctions and shut-down of fault systems without interrupting the vehicle operations. Moreover, it has a modular control system by Saab Seaeye and a fully configurable power distribution system. 

The main characteristics of this vehicle include: 

  • operational depth of up to 2000 m 
  • 80 kg payload
  • wide range of optional quick-change tool skids
  • power distribution system
  • self-diagnostics
  • modular control system
  • length/width/height: 1515/905/1000 mm

Falcon by Seaeye

Due to its capabilities, wide range of operations and flawless performance of its tasks, the Falcon by Seaeye is the choice of many leading operators. This lightweight and portable vehicle works wherever the measurements need to be conducted – in coastal waters, open seas as well as in tunnels.
The choice of tools and accessories makes it a perfect platform for the performance of intricate and demanding missions in the water depths. 

Its main characteristics are: 

  • operational depth of up to 300 m
  • 14 kg payload
  • integrated system diagnostics
  • high-resolution colour camera
  • illuminator with a variable maximum luminous intensity of up to 6400 lumen
  • single-phase power supply 100–270 VAC at 2.8 kW
  • length/width/height: 1000/600/500 mm
  • weight: approx. 78 kg (including freshwater ballast) 

Seaeye 600DT

The Seaeye 600DT System is designed for operations to a depth of 300 metres. The 600DT is the latest evolution of the original Seaeye 600 introduced in the mid-1980s. The original hydrodynamic shape remained unchanged but the modern digital electronics, control technology and the latest Seaeye SM4 thrusters added to this model enhanced the power and performance of this internationally established observation ROV. The forward speed of the Seaeye 600DT is over three knots.

USBL UNDERWATER POSITIONING SYSTEM

The Ultra-Short BaseLine (USBL) system includes the Sonardyne Ranger Pro

The operation range of the Ranger Pro USBL is 6000 m. The system allows tracking of up to ten targets in the water depth, e.g. ROVs, divers, AUVs, or towed gear. The system calculates the position of a given underwater object based on the measurements of distance and angle between a head located on the vessel (r/v IMOR) and the acoustic transponder installed on the object. Such positioning may be used during underwater inspections, in subsea archaeology, or surveys of cables and pipelines.

Technical specification

  • Operation range: > 6 000 m (confirmed)
  • Acoustic coverage: ±90° or ±50° (depending on the transceiver used)
  • Tracking: 1 vehicle on the surface and 10 underwater objects
  • Maximum refresh rate: every 1 s, irrespective of the water depth
