We have delivered several towed vehicles to date. Each project was a collaborative effort with the operator to provide a platform made to carry their specific payload.

Passive sleds are best suited for deeper applications, and when depth of operation is controlled by how much cable is paid in and out.

Active sleds are fitted with dive wings and/or elevons that the operator can control from the ship. They are used when the applications call for frequent undulations or altitude keeping, etc.

USGS Bio-acoustic Sled

If your applications require covering large areas and gathering big data, a remotely operated towed vehicle is a great solution.

Our design philosophy:

Adjustable ballast and buoyancy

Adjustable tow-point

Adjustable control surfaces to minimize pitch and roll

 

Protective elements that can be quickly replaced in case of failure in the field

Large U-bolts and/or anchoring points for tag-lines

Smooth under-carriage to slide the sled onto the deck and ease recovery

Tow Fish and Smaller Sleds

Our smaller platforms have a great track record and can be fitted with affordable navigation system (see our NavBox) and/or a ROV-style twisted-wire telemetry pod.

Our architecture of choice:

Bellamare Mux.jpg

A Fiber-optic tether allowing for very high data rate (from 2.5Gbps and up).

 

Mux cards that provide each sensor their own independent channel

Bellamare Relay.jpg

Add Relays, A/D Cards, Motors Drivers

and Power bricks for automation and control.
