Rapid Mobilization

Our Falcon DR ROV spread has the capability to dive up to 1000m. Our equipment can be broken down into airfreight-ready components or all installed into a single 20ft shipping container. We are able to get onto location and surveying in a fast and cost-efficient manner.

Pre-Salvage Surveys

A sunken vessel or asset is an unknown risk. It may be risk to personnel, risk to navigation, risk to environmental damage, risk to commerce and the list goes on. One way or another, risk equates to cost. SeaView Systems provides cost-effective means of reducing the unknown, thereby reducing risk and cost.

High Resolution Multibeam Sonar Survey

The survey services we are able to perform go beyond simple video. By installing an inertial measurement unit (IMU) on the ROV along with a multibeam profiling sonar and ultra short baseline acoustic tracking, we are able to equip the ROV to perform very high resolution multibeam surveys of the wreck site. From this survey, we can build a fully geo-referenced 3-D model of the vessel and when this model is referenced to known drawings, we can identify and locate the position of oil tanks, access ways and other points of interest.

HD Video Survey

Sometimes a picture is the only thing that can tell the story. As standard, we carry up to three NTSC quality video cameras but for special cases requiring the best video available, we have built into our system the ability to support HD videography. This video is supported by a high intensity LED lamp providing 50,000 lumens of light to the subject.

Digital Still Imagery

For even more detailed imagery, we have had excellent results on recording images with a combination of a digital stills camera and our Newtsun LED lamp. This image of Lophelia coral was recorded using this combination and was used as the front cover image of the July/Aug 2009 issue of Ocean News and Technology magazine.

Small Vehicles Doing Big Jobs

Once on location, we are able to do more than just survey. Using our standard 5-function manipulator or custom tooling and a lot of ingenuity we are able to leverage this capability to execute significant tasks.

An example of how a small vehicle can perform complicated tasks is illustrated from 2006 when Tyco Telecommunications had an umbilical part on one of their eight ton trenching systems while working in Venezuela. The trencher was sitting in approximately 240ft of water and it was highly urgent to get it back on board; there was no time to organize a mixed gas diving spread.

Tyco contracted SeaView Systems to fly down to Venezuela with our small SeaBotix ROV (checked in baggage on a commercial flight). Once onboard, we used a light messenger line and attached it to a short rod. The rod was placed in the small, single function grabber on the SeaBotix and the ROV dove down to the trencher and poked the rod through the lifting yolk coming out of the top of the trencher. Once the line was through the yolk, we went around the back of the yolk, grabbed the rod again and brought it back onboard drawing the small messenger line to the surface as we came. The messenger line was then connected to a heavier line which in turn was passed through the yolk back and brought back to surface and exchanged for a lifting hawser. With the heavy hawser moused through the yolk and back to surface, the trencher was brought back safely onboard. In this manner a 28lb ROV salvaged a 16,000lb trencher!

Smart Grapple

SeaView originally designed our Smart Grapple to remove debris from the bottom of a 400ft deep water-filled shaft. The same tool is applicable for lifting objects from the seabed. This tool may be suspended by a lifting line or umbilical for a maximum lift of 1500lb. It can be fitted with a range of jaw combinations suitable for the recovery of heavy items down to small fragments in a closing scoop jaw.
