INTEGRATED CAISSON TEAM (ICT)
OPERATING MODEL
INTRODUCTION: Due to platform life extension,
Caissons have often been in place longer
than planned, and deterioration and failure of
Caissons is a growing trend in the North Sea
and worldwide. This deterioration and failure
may present a dropped object risk to subsea
structural and piping systems.
The Integrated Caisson Team (ICT) is a Global
Energy Group Production IRM initiative that
provides a cost efficient and value added
turnkey Caisson solution and “one-stop” shop service consisting of the following
capabilities:
Initial Integrity Inspection
Survey
Caisson Design
Caisson Fabrication
Caisson Destruct
Caisson Installation
Caisson Repairs
Caisson Maintenance
The philosophy behind the ICT model is the provision of a “one-stop” Caisson
remediation and replacement offering that identifies best value solutions by
combining the services of selected ICT Partners throughout the project lifecycle.
Key to the ICT philosophy is the decision by GEG PIRM not to add mark-ups to other
ICT Member services and end deliverables
Of significant value is the ability of the ICT to offer options to a variety of solutions from
within the structure of the ICT, without the requirement to bring in additional external
resources.
Examples include:
Options for either welded or weldless connections of Caisson sections
Use of conventional rigging equipment or specialist Caisson lifting tools during
destruct and construct
Options to coat Caissons with Client specified coating systems or utilisation of
1 coat systems complete with coating warranties during the fabrication
process
Option to install Marine Growth Prevention Systems at time of Caisson
installations, or as retrofit solutions to existing Caissons (this option is available
to Risers, Conductors, and structural tubulars)
Options for nitrox diving capability to 50mtr or Cofferdam support in the splash
zone
Alternative access solutions including rope access, WEB Deck and tension
netting systems, all installed by multi-disciplined access and trade technicians
Options for platform, vessel or daughter craft based diving operations
