Complete Shutdown – POSH Arcadia – TPAR

The Engport Group was contracted by POSH to carry out the complete shutdown of the Arcadia platform during its maintenance stop at the Angra dos Reis Port Terminal. This project represented one of the most complex and comprehensive operations of 2024, mobilizing a multidisciplinary team of over 40 highly skilled professionals who worked continuously in 12-hour shifts for 50 days.

TECHNICAL CHALLENGE

The main technical challenge focused on lifting the platform’s thrusters – critical multi-ton equipment responsible for the dynamic positioning system. Lifting these components required rigorous load handling procedures, with zero margin for error.

ENGPORT ENGINEERING SOLUTION

• Our engineering team developed an optimized rigging procedure specifically for the Arcadia’s thrusters. Through detailed structural analysis, load simulations, and careful selection of lifting equipment, we implemented significant improvements in the traditional handling system, increasing operational safety and reducing execution time by approximately 30%.

   

  SCOPE OF WORK

   

  Thrusters Maintenance:

   

• Lifting and safe removal of 6 propulsion units
• Complete disassembly for inspection
• Replacement of worn components
• Dynamic balancing and precision alignment

Access Infrastructure:

• Assembly of 300m² certified scaffolding

Working at Heights (IRATA):

• Anticorrosive treatment on lifeboat davits
• Fire line removal
• Corrosion point treatment in hard-to-reach areas
• Boilermaking and welding at heights

Surface Preparation:

• Complete scraping of the platform’s hull
