Client

Valaris

The Client asked us to look at the Interface between the Jack-Up Rig and the fixed Installation by means of a bridge access platform. Our client’s requirement was due the contract for the plug and abandonment of existing wells to allow the decommissioning of the Platform.

The Solution

TEXO was successful in securing this project because we were able to offer our client a turnkey solution that included design, engineering, fabrication, and installation. This all-incumbent service meant that our client was able to maintain budgets by employing a single contractor.

TEXO Engineering & Fabrication designed a series of grillage walkways to allow the interface with the Jack-Ups tension deck and the installations existing bridge pivot point.

We then carried out the fabrication to the detailed design drawings produced which included inspection and coating, this was delivered to site and trial assembled at the quayside location.

TEXO also carried out the installation work offshore using rope access to safely work on the rig’s tension deck.

In total, this project took more than 2,500 hours, including 315 hours for design and engineering, 1080 hours of fabrication and 1230 hours of installation.

The results

This project was completed successfully, despite challenges that included tight material procurement schedules to meet delivery for fabrication. We also worked within weather constraints for the offshore installation.

TEXO managed to turn a 16/18 week project around in just 13 weeks from original design concept to installation by utilising all TEXO’s internal service offerings.
