  • Description
  • Characteristics

The Manta-200 is Geomil Equipment’s most capable Cone Penetration Testing (CPT) system for seabed operations. Since its introduction in 2013 it has successfully completed challenging projects around the world and its performance is unsurpassed.
Available in two different depth configurations, the Manta-200 is suitable for almost any project: • Shallow Water (SW), up to 150 m water depth. • Deep Water (DW), up to 1,500 m.
Constant tension (CT) winches are available to support deployment at the various working depths. The Manta-200 is built around our in-house developed Continuous Drive System (CDS) that was designed with a clear focus on durability and high production. It also guarantees uninterrupted penetration of the cone.

A standard Manta-200 package consists of the following items:
• Base frame with CDS drive.
• Fully integrated submersible power pack with PTO function.
• Standard skirt.
• Hoisting frame (32 mm hoisting wire).
• Control and data acquisition unit.

The Manta-200 measures 2,200 x 2,200 x 2,300 mm (L x W x H) when being transported. The basic setup is transportable in 20 ft sea containers.

Optional supporting items:
• Main hoisting winch.
• Rod winch (CT).
• Umbilical winch (CT).
• Skirts in various designs.
• Hoisting frames in various designs.
• Several flexible ballasting options.
• Push force measurement.
• Leveling frame XY-20.
• Seismic CPT.

Main characteristics of the Manta-200:
• Power and communication via umbilical.
• Modular system weight 5 - 28 tons.
• Thrust capacity 0 - 200 kN, optionally 250 kN.
• Variable penetration rate 0 - 80 mm/s.
• Variable retraction speed 0 - 80 mm/s.
• Real-time CPT data at surface.
• Capable of driving 55 mm casing tubes.
