What is the TSP?

Towable survey Platform (TSP) is a floating, towablevessel that can support a complete multibeam and/orDoppler survey suite.

The TSP relieves the user of mobilization anddemobilization costs for small to medium sizedsurveys.

Managing vertical datum

Squat/ Settlement(Sinkage/Trim)

Tide corrected data1. TRDI will provide a

squat/Settlement curve for theTSP carrying full instrumentationpackage

2. Operator will need to keep in nullof near field wave train

KGPS corrected data1. Put the TSP anywhere. KGPS

handles the Squat/Settlementissue

Towing Characteristics

Will operate at up to 7 knots.

Will maintain relative position WRT towing vessel.

Tow position can be adjusted by user.

Designed for protected waters but is operable inrougher seas.


20/23

Physical Characteristics

Can be deployed and recovered by 2 people when fully instrumented

1 person with mast removed

Fits between the wheel wells of a standard pickup

truck.

Relative positions of sensors is maintainedbetween Mob.s. (recalibration not required)

Mast with instrumentation can be used withoutplatform.
