When precise or reliable dynamic positioning is critical, our inertial navigation systems coupled with DGPS (Differential GPS) and/or Acoustic technologies such as USBL (Ultra Short Base Line) offers superior accuracy and reliability for your offshore operations. Our Dynamic Position reference sensor D-PINS is the most cost effective method of adding redundancy to your existing DP systems. D-PINS offers minutes of accurate positioning during outages which greatly reduces cost and risk associated with these conventional reference sensor system outages. Our inertial navigation solution can be easily integrated with any DP desk and system configuration. Using the D-PINS inertial navigation system greatly reduces costs associated with rig and construction vessel time while adding reliability.

Reliable Position Reference Sensors

The most reliable deep water sensors  for dynamic positioning are DGPS, Acoustic and Inertial Navigation. Both DGPS and Acoustic technologies are reliable but do have their drawbacks such as signal degradation due to weather or noise interference. While Inertial Navigation cannot be used alone, used in tandem with DGPS and/or Acoustic it not only offers reliability but improved accuracy including with heading and attitude.

USBL Smoothing for Dynamic Positioning

Repeatability in acoustic navigation systems is key to proper dynamic positioning. By using the D-PINS system you dramatically increase that repeatability of your existing USBL solution. Our system intelligently combines the noisy USBL data with very high update rate, low noise inertial data.
