Which combination is suitable for supply operations during lifting activities in more than 350m depth?

In supply operations during lifting activities at depths greater than 350 meters, the selection of positioning technologies is critical for ensuring safety and accuracy. The combination of Inertial Navigation, Acoustic (LBL), and Radar is particularly suitable due to several factors.

Inertial Navigation systems are capable of providing continuous positioning data in environments where other systems may have limitations, such as when satellite signals may be compromised by obstructions or when operating at significant depths. This makes it essential for maintaining an accurate position during complex lifting operations.

Acoustic systems, specifically Long Base Line (LBL) positioning systems, are highly effective underwater positioning tools at substantial depths. LBL utilizes a network of acoustically activated transponders to determine the position of the vessel in relation to the seafloor, providing reliable data in environments where GPS is either unavailable or unreliable.

Radar, while primarily a surface-based system, can complement these technologies by providing situational awareness and surface positioning information, which can be particularly important when navigating close to operational sites.

Therefore, the combination of Inertial Navigation, Acoustic (LBL), and Radar effectively addresses the challenges posed by lifting activities at over 350 meters in depth, ensuring operational safety and precision.
