Wilson Sons Completes Second Maintenance Docking for Brazilian Navy Patrol Vessel

Wilson Sons has successfully docked a Brazilian Navy patrol ship at its shipyard in Guarujá, São Paulo, located in the Port of Santos for the second time. The Guajará vessel, which underwent maintenance for nearly two months, was delivered to the Navy in the second half of December.

Launched in 1994, the NPa Guajará (P44), responsible for patrolling the Santos region, boasts dimensions of 46.5 meters in length, 7.5 meters in width, and a draft of 2.3 meters. The vessel belongs to the Grajaú Class and displaces 197 tons of water (standard) and 217 tons when loaded. In 2021, the Navy had previously selected Wilson Sons to perform the docking of another patrol ship, the Guaporé.

Docking is a mandatory preventive maintenance procedure carried out every five years. The vessel is lifted from the water to review its structure and hull plates during this process.

Approximately 150 professionals participated in the docking services for the patrol ship, including boilermakers, welders, painters, and administrative staff. The services included treatment and painting—both external, on the hull, and internal, in the tanks—replacement of steel plates (around 4 tons), and substituting sacrificial anodes.

Two new tugboats to be delivered in 2024

Wilson Sons is also constructing six tugboats with more sustainable technology at its shipyards in Guarujá. Four of these have already been delivered starting from July 2022 (WS Centaurus, WS Orion, WS Rosalvo, and WS Castor), with the remaining two slated for delivery in 2024.

These tugboats, boasting over 90 tons of static traction, represent the first in Brazil to adhere to the IMO TIER III standard set by the International Maritime Organization. The new hull design of these vessels allows for a reduction in greenhouse gas emissions, with an estimated 14% decrease in fossil fuel consumption, contributing to improving air quality in the ports where they operate.
