Drilling, Completions & Well Test Support

Seafastening, walkways, stairways and access platforms, and double stacking of containers and well test equipment. Design, fabrication and routing of ASME B31.3 compliant pipework, pipe supports and restraints, and pipe stress analysis. Lift plans and deck layout drawings, along with design, load testing and installation of flarebooms and kingposts, including retrofits of existing rig structures to support temporary flaring activities.

C Plate design and supply, and bespoke drillpipe and casing subs, flowbranches and crossovers. Gravel pack support, including deck layout planning and seafastening for third party gravel pack modules, with 3D modelling and laser scan clash detection used to minimise offshore welding. Interfacing of coiled tubing and wireline equipment, including sequencing the installation of CT injector units and the wireline BOP within the envelope of the tension lift frame or Coiled Tubing Lift Frame. Marine riser tensioner capacity increases, piping and valve upgrades to drilling mud systems and well test lines, false rotary table design to save critical path tool make up time, and temporary firewall installation for well testing. Planning of subsea equipment installation and on board storage during cyclones and bad weather, and design and installation of skidding systems for handling subsea equipment including trees and flowbases.

Repairs, upgrades and improvements to HWUs used for fixed platform workover operations, including gin pole overhauls and access platform rebuilds. Structural re-analysis and re-certification for increased wind speeds under cyclonic conditions, and safety improvements such as remotely operable pin locking devices that eliminate work at height tasks.

Advanced design and analysis capability for conductor tensioning and related equipment, covering string loads, tensioning programmes and simplified vortex induced vibration (VIV) review, tailored to each client’s drilling programme.
