Paulo Cantergiani, Market Intelligence Intern at WSB Advisors, conducted a comparative study of Brazil’s offshore support vessels (OSV) fleet, analyzing May 2024 against the same period this year. Drawing from exclusive data within WSB. One, our database, the study reveals important trends shaping the sector’s evolving dynamics.
AHTS vessels recorded the sharpest decline, dropping from 53 to 50 units, a 5.7% contraction. The reduction reflects a temporary gap in chartering activity, largely linked to the timing of Petrobras tenders currently being finalized.
Meanwhile, the RSV segment remained stable, with 28 active units throughout the period, reinforcing the steady demand for subsea inspection and maintenance services critical to offshore infrastructure integrity.
PSV numbers also saw a slight reduction, from 129 units in May 2024 to 122 in May 2025. a 5.4% contraction.
The findings highlight the differentiated behavior of each OSV segment and reinforce the value of real-time and data-driven decision-making. In a volatile market, access to accurate and granular fleet information remains a key asset for anticipating shifts and aligning commercial strategies.
