“Assuring safe and on-time delivery by excellent teamwork.”
TAQA-operated Peak Gas Installation (PGI) is an underground natural gas reservoir in Alkmaar, Netherlands. It stores and delivers natural gas to meet peak demand from the Dutch national grid. Conbit was given the contract to replace the guy wires and earthing system and work on the vent tips.
Conbit conducted a site visit to devise a method statement and structural calculation for the guy wire tensioning. TAQA provided the new guy wire type and diameter records, which were checked and reviewed by Conbit’s structural engineers. This site visit enabled the team to determine the exact lengths allowing them to procure custom-made, certified guy wire replacements.
All preparation ensures the safety and effectiveness of the entire process.
Conbit took into account both the exact guy wire tension values provided by the engineers and the relevant environmental conditions like the wind and temperature. Conbit technicians used hand-operated rigging tools in combination with a load meter to measure the tension in the line.
The skilled team of engineers and rope-access technicians provided the full-service package for guy-wired structures. These services include structural engineering, inspection, repair, maintenance, and certification.
Operation & maintenance
Mammoet provided the installation crane and IRATA the rope access techniques to manage the removal and reinstallation of the tip. Both were also used as flange maintenance on the flare stack itself. Not only was this combined solution the best possible for the task, but it’s also 100% compliant with the latest changes in Dutch OSH legislation.
The whole maintenance process was carried out by qualified Conbit and Mammoet crews consisting of rope access technicians, crane operators, and banksmen. Conbit and Mammoet’s extensive experience led this guy wire replacement project to a successful outcome.
