D-PINS

Dynamic Positioning – Inertial Position Reference Sensor

D-PINS is an aided inertial position reference sensor specifically designed to provide reliable position inputs to any DP desk through short term outages of either / both DGPS or acoustics. By removing the position jitter from ultra-short baseline (USBL) acoustic positioning systems in deep water, D-PINS significantly reduces rig or construction vessel time when moving onto location.

D-PINS is easily installed into customers’ existing configurations. Initially, the D-PINS system can be run offline to allow operator familiarity while logging DGPS, acoustic, and D-PINS data for comparison. Once operators are fully trained, D-PINS can be brought on line like any other position reference sensor. Standard DGPS and acoustic telegrams from existing systems are blended with data from a navigation grade inertial measurement unit to deliver a position telegram into an open position reference slot within the DP desk.

D-PINS delivers the same precision as conventional DGPS or acoustic positioning system, and has the capability to provide very precise heading and attitude data.
