Gas compressor platform CA-KU-A1, Altamira, Tamaulipas/Mexico

The gas compressor platform CA-KU-A1 was erected at the shipyard of Dragados Offshore in Tamaulipas/Mexico with the aid of comprehensive PERI scaffolding solutions.
CA-KU-A1 has a weight of 23,900 tonnes and can compress around 450 MMcf of sour gas per day.
It was possible to adapt the suspended working platforms variably in 25 cm increments to account for the gaps between the steel girders. Scaffold tubes and couplings were used to fix them to the steel girders of the platform.
The modular PERI UP Flex scaffold system made for safe working platforms in the node points of the jacket.
PERI engineers were on site to assist the construction site team with the assembly of the ALPHAKIT Towers which supported the tripods.
Access to the platform was provided by two clever PERI UP Flex Staircases 100 – these were also used to ensure that shift changes ran smoothly.

Project data

Location: Altamira, Mexico

  • Supporting the construction of the 23,900 tonne gas compressor platform CA-KU-A1 at the Dragados Offshore shipyard in the federal state of Tamaulipas, Mexico
  • The objective is to increase gas production in the oil and gas production complex of the Ku-MaloobZaap field (KMZ) in the bay of Campeche
  • The platform consists of a “topside” (main core of the platform) including a compressor unit, a jacket for anchoring the station to the seabed and two connecting bridges that are anchored using two tripods

Requirements

  • Complex platform geometry, necessity to build around numerous obstructions
  • Demanding schedule must be adhered to, materials must be supplied in line with requirements
  • Multiple workers must be able to access platform at the same time
  • Transfer of high tripod loads

Customer

For Dragados the most important thing to consider is safety. Safety is above everything for us and PERI Scaffolding flexibility guarantees safety. The possibility of using it as a suspended solution is a great advantage against the competition as not every product in the market offers this solution. We have used PERI Scaffolding and ALPHAKIT in this project, saving tons of steel, lots of cm3 of weld making the project more profitable to us. PERI Scaffolding adjusts more to our projects because of the continuous changes in the construction site and the adaptability of PERI Scaffolding works really fine with that.

PERI solution

  • Use of modular PERI UP Flex scaffolding system to assemble safe working platforms at any height and straightforward construction around obstructions like pipe connections
  • Assembly of working platforms consisting largely of suspended working platforms in a 25 cm system grid that were fixed to the steel girders of the platform using scaffold tubes and couplings
  • Installation of the PERI UP Flex Staircase 100 at two corners of the platform to provide simultaneous access for up to 500 workers within 30 to 60 minutes
  • On-schedule supply of a total of 700 tonnes of PERI scaffold material on a rentable basis
  • Transfer of high tripod loads using ALPHAKIT Towers with integrated working platform for parallel use
  • Manual assembly of low number of lightweight ALPHAKIT system components on the ground and subsequent erection by crane with the assistance of PERI Support on site
