All Seaeye ROVs have been developed from original specifications developed in cooperation with ROV companies working in the offshore oil and gas industry where Seaeye ROVs enjoy a market leading position, and with companies whose requirements require portable but equally capable systems. In the ongoing development of these systems, account has also been taken of the requirements of military and paramilitary customers who require the benefits of 'commercial off-the-shelf' or 'COTS' systems for security, diver support, search, salvage, MCM and survey operations. In recent years, Seaeye has worked closely with various navy customers to develop work ROVs capable of intervening in support of distressed submarines.
Other customers use Seaeye ROVs for internal tunnel inspection, environmental work, scientific research and hydrographic applications. Others are used in the super yacht industry. In the Seaeye range you should find a standard system suitable for almost any requirement. Or maybe there is something very close that can be modified and customised for your application.
Seaeye Falcon & Seaeye Falcon DR
The Seaeye Falcon is a portable but extremely powerful system, with its one to one power to weight ratio and is the professional solution for depths of up to 300 metres in coastal and inshore waters. A wide range of standard tools and accessories can be fitted. For deeper operations to 1000 metres depth or for tasks that require long umbilicals the Falcon DR is available.
The best selling Seaeye Tiger is the yard stick by which all other small electric ROVs are measured in the offshore oil and gas industry. Very powerful, easy to fly and rated for operations to 1000 metres, the Seaeye Tiger is the industry work horse for observation, inspection, search, survey and diver support. It is also operated by military clients in support of search, rescue and salvage operations.
Rated to 1500m, the Seaeye Lynx was developed to meet an original specification from Acergy. Larger than the Tiger but with similar performance, this system has two vertical thrusters and additional outlets and power supplies for survey sensors. A variety of interchangeable tooling skids can be fitted. Thales also operate this system that replaces the earlier Seaeye Puma. For a small increase in cost this system is a very effective deeper rated alternative to the Seaeye Tiger.
The Seaeye Cougar-XT is a compact, highly flexible and extremely powerful electric ROV with working depths of 2000 metres. Proven worldwide and recognised for its capability, operators now have the ability to undertake a range of demanding work tasks at much lower operating costs. The Seaeye Cougar-XT is designed to accommodate heavier duty tooling via a system of quick-change tool skids making it ideal for survey work, drill support, light construction projects and salvage support operations. Four vectored horizontal and two vertical brushless SM7 500 Volt DC thrusters provide full three-dimensional control of the Cougar-XT and the highest thrust to weight ratio in its class.
The Seaeye Cougar-XTi is the deep water version of the compact, highly flexible and extremely powerful Cougar-XT. With all the benefits of the XT and the full range of optional quick-change tool skids, the Cougar-XTi also features a new concept in power distribution, self-diagnostics and a newly designed modular control system.
The Seaeye Panther-XT is a development of the successful Seaeye Panther Plus ROV, which was developed in partnership with ROVTECH whose requirements were to minimise the system's weight and deck space requirements, while increasing the thrust and performance envelope to allow operations in the most demanding conditions encountered during IRM operations.
It is customisable and designed as the Saab Seaeye benchmark for electric work ROVs and challenges heavier and more costly hydraulic vehicles, particularly where deck space is at a premium. Thanks to its 500V powered thrusters, the Seaeye Panther-XT benefits from excellent handling and is capable of accommodating a wider range of heavier duty tooling for work tasks including drill support, pipeline survey, salvage and IRM to depths of 1500 metres. Air transportable Seaeye Panther systems are also supplied for intervention and life support tasks in support of rapid response submarine rescue.
ROVTECH claim that their Panthers can still keep going after their hydraulic ROVs have to be recovered in the strongest Southern North Sea currents. The Panther-XT is also widely used in the Middle East for pipe survey and in Vietnam for drill support and survey operations by PTSC.
The Seaeye Jaguar represents a new era in ROV design and continues the long tradition of innovation and excellence that Saab Seaeye is world renown for. The largest vehicle in Saab Seaeye's range, the. Jaguar introduces a new concept in control and power distribution that ensures reliability and complete redundancy throughout the vehicle. Easy self diagnostics and the ability to fix problems while the vehicle is working are a key part of the new control software.
It gives precise control and is designed with an easy to use interface so that the system can be easily reconfigured. The modular design of the new control software means that future platforms will benefit from commonality of parts and therefore lower maintenance and spares requirements. With a standard operational depth of 3000msw and options of up to 6000msw, most subsea applications are within its range and capabilities.
ROV handling & TMS systems
ROV Launch and Recovery Systems (LARS)
The essential elements of an ROV Launch and Recovery System (LARS) are:
An umbilical winch with sufficient capacity to accommodate the maximum length and diameter of ROV umbilical that the system requires. The winch will normally be fitted with a level wind mechanism to ensure even spooling of the umbilical cable onto the winch drum. A hydraulic winch motor is installed in the winch that is suitably sized to cater for the size of winch drum selected as well as the weight of the deployed ROV and TMS together with the umbilical weight and any dynamic amplification factors to be applied to the design.
Slip Ring. An appropriate slip ring with sufficient passes to match the conductors required in the umbilical needs to be specified and to be installed in the winch drum.
'A' Frame or Crane. A mechanism is needed to lift and overboard the ROV. This can be a crane or 'A' frame suitably rated to accommodate the maximum weight to be deployed including the weight of umbilical in air or water, (whichever is greater), and the applied dynamic amplification factor specified which is usually 3G. For self contained packages, 'A' frame systems are generally preferred and in the standard Saab Seaeye range these include an elevated pivot point to allow clearance of the ROV and its TMS over the ship's side or guard rails. Due to their smaller footprint, Crane LARS can be used when deck space is at a premium.
Sheave. A sheave wheel is fitted to the crane or 'A' frame of greater diameter than the minimum bend radius of the ROV umbilical. For safer handling it is recommended that the optional lock latch mechanism be incorporated with the sheave wheel to capture the ROV (or TMS) bullet during over boarding and recovery.
Hydraulic Power Unit (HPU). A suitably sized HPU is required to provide hydraulic power to the winch, 'A' frame rams and lock latch mechanism.
Mounting Skid. Although winches, 'A' frames and an HPU can be provided as stand alone units, for ease of transport and mobilisation, it is generally preferred to provide a complete LARS package mounted on a dedicated skid base that can be welded to the deck
The alternative to 'Free Swimming' an ROV is the use of a TMS (Tether Management System) to deploy an ROV to the working depth. This option adds an element of cost to your investment in an ROV system but offers a number of significant benefits including:
- Eliminating the effect of drag on a long length of surface tended umbilical.
- Providing protection to the ROV garaged in the TMS during launch and recovery, particularly as it passes through the splash zone.
- Increasing the speed of travel to and from the working depth. The speed of the lift winch and not the rate of dive of the ROV now determines the speed of launch and recovery.
- Achieving greater accuracy of deployment to the work site.
- Providing a safe haven to park the ROV at depth between tasks.
Control and Workshop cabins
The surface control and power supply equipment necessary to operate a Seaeye ROV can be provided boxed as individual transportable items or for you to install as a fixed installation in your vessel.
Alternatively, Seaeye can install all of this equipment into a dedicated control container or 'cabin' that can be moved from location to location as a complete and integrated unit. The package will include domestic power supplies, a desk, chairs and a bookshelf for the storage of system manuals. 19 inch rack mount units are provided with the Seaeye surface control unit installed as well as the installation of customer selected options such as a video suite, sonar control equipment, communications equipment and so on. The Seaeye Power Supply Unit will be installed together with all interconnecting wires and cables.
Options include air conditioning and the choice of a cabin suitable for safe area ROV operations or operations in a hazardous area with 'Zone 2 rating'. Control cabins can also be manufactured with an A60 fire rating.
