Sonardyne Delivers Fusion 2 Remote Operations First

Sonardyne reports successfully provid- ing remote Fusion 2 survey operations capability on a live subsea construction campaign in the U.S. Gulf of Mexico.

Using its new Remote Operations Ac- cess Module (ROAM), Sonardyne sur- veyors based in the UK were able to remotely access and operate the Fusion 2 survey and construction software on- board Subsea 7 vessels in the Gulf of

Mexico, signi? cant from the Sonardyne perspective as it de-risks the upgrade to

Fusion 2, mitigating international travel restrictions road blocks.

Fusion 2 is designed to streamline off- shore ? eld development operations by reducing the time and capital expen- diture needed to undertake survey and construction tasks, combining tradi- tional Long BaseLine (LBL) and inertial navigation system (INS) techniques in

EvoLogics one, enabling the ability to perform real- releases SiNAPS time simultaneous location and mapping 2, the upgraded (SLAM) calibration of sparse seabed acoustic posi- transponder arrays. tioning software

ROAM is a portable communications link in a box which can operate over satellite or any other available network, such as 4G/5G and vessel Wi-Fi, provid- ing secure access between Sonardyne engineers and any vessel needing remote expert assistance.

The remote operations service was pro- vided last summer during a deepwater campaign on the Mad Dog Phase 2 proj- ect in the U.S. Gulf of Mexico, where

Subsea 7 onboard surveyors were able to undertake remote training in Fusion 2 prior to deployment. Using ROAM, So- nardyne surveyors working onshore in the UK were able to work shifts along- side their counterparts onboard the ves- sel in Fusion 2, supporting live position- ing operations and taking secure control if required.
