and export cables in water depths ranging from 7 to 40 m.UTEC will provide equipment and personnel for online survey, surface positioning and offline data processing and reporting on board an anchor handling tug supply vessel. The equipment includes the Veripos LD8 receivers, iXBlue Octans Surface gyrocompass and Vaisala digital barometers. UTEC also provided trenching survey support on the first phase of the project, which was completed in November 2023. Upon completion, the wind farm will generate approximately 2.4 TWh of clean energy annually.TCP’s Phase 2 offshore wind project was initiated

meters.IMO-HSC certified, the Octans AHRS will enhance Bourbon vessels’ efficiency in installation, maintenance, and repair tasks for the oil and gas, and offshore wind industries, according to Exail.Providing measurements for roll, pitch, and heave, Octans will serve as a survey-grade surface gyrocompass and motion sensor, integrated into the vessels' Class 3 dynamic positioning (DP3) system.This integration will ensure precise positioning and stabilization over underwater structures, ensuring the safe deployment of cranes, remotely operated vehicles (ROVs), and supporting efficient survey
USCG's Keeper Class Buoy Tenders Set for Navigation Upgrade
The U.S. Coast Guard (USCG) has tapped Exail to replace obsolete gyrocompass systems on the 175-foot WLM Keeper Class Buoy Tenders. The $2,244,009 contract awarded to Exail includes Octans gyrocompasses and Netans Navigation Data Distribution Systems (NDDS) and covers a base year and nine options over a 10-year performance period.This upgrade will provide the USCG Keeper Class Buoy Tenders with more precise and dependable navigation capabilities. Built on Exail’s Fiber-Optic Gyroscope (FOG) technology, the Octans gyrocompass will ensure highly reliable and precise navigation data, the

with Advanced Navigation’s AI based fusion algorithm to deliver accurate and precise navigation. The system features ultra-fast gyro compassing, acquiring and maintaining an accurate heading under the most demanding conditions. While D70 does contain a GNSS receiver, it’s not required for gyrocompass operation.Based on DFOG technology, D70 delivers a 40% reduction in size, weight, power and cost (SWaP-C), when compared to systems of similar performance.0.01° roll and pitch0.1° secant latitude heading (gyrocompass)0.01° /hour bias instability10mm position accuracyThe Boreas SeriesThe

knowing the DVL’s exact alignment. To this end, the system was calibrated in coastal waters where the DVL’s acoustic signals can reach the seabed. The bottom tracking of the DVL measures sailboat velocity relative to the seabed. Merging these data with heading from a fiber-optic gyrocompass delivers sailboat velocity and trackline in earth coordinates. GPS data can supply similar information. Comparing these two data records reveals the alignment angle between the DVL and the boat’s heading. Once the Teledyne Explorer DVL’s performance was validated, its output
