FT550 Vibrocorer

With its modular construction, high power variable frequency, sensor capabilities, and software control, Feritech’s vibrocorer is one of the most versatile on the market.

The 3rd generation FT550 variable frequency, high power Vibrocorer is lightweight and leads the market in its technical innovation and performance. The subsea equipment is built to withstand the harsh offshore environment and unforgiving handling. Due to its simple-to-assemble modular construction, the system can be mobilised very quickly for cores of 1-12m.

Our advanced integrated software informs the engineer of the information he needs to ensure efficient, successful and safe deployment and operation.

Frequency and thrust control

The system allows the user to adjust the vibrational frequency and effective thrust in real time. this ensures samples are collected with the minimum of disturbance of the ground but with the advantage of being able to turn up the penetration force when needed to ensure effective penetration and recovery of compacted samples with in the stratigraphy.

Force increases with an exponential curve against motor frequency, also amplitude is a theoretical constant. This is due to the operating frequency being much larger than the resonant frequency of the system. The amplitude above this range tends to the constant max value. You do experience a larger amplitude as the unit passes through various resonant frequencies of the system during start-up and run-down and frequency adjustment through resonant bands.

High Power, Variable Frequency

Feritech Global’s Vibrocorer is the only system on the market with an integrated high power variable frequency system. By using this unique variable frequency system, sample disturbance is minimised, ensuring a high quality sample regardless of high power settings.

Heat Flow Probe

Modular and quick to mobilise

The system is modular and very easy to use. It can be configured to collect cores from 1m to 12m long in 1m increments and is very quick to mobilise either onboard or on the quayside.
The frame is made from common modules that can be quickly configured to collect the required core length.

Barrel swap in any position

Unlike any other Vibrocorer system, our Vibrocorer can be deployed and recovered to deck in the horizontal or vertical axis without requiring a LARS. Barrels can be swapped in either position meaning that the user can choose the best deployment and recovery method for the vessel they are operating from.
