MODU & Vessel Modifications

Engineering and execution support for structural upgrades, deck modifications and local strengthening on MODUs and offshore vessels.

Design and supply of conductor tension decks for jackup rigs, including standardised designs for early generation rigs and fixed or sliding extensions for existing conductor deck designs. Designs consider variable and fixed positioning options and client drilling envelope requirements.

Engineering, fabrication and installation of modifications and upgrades to moon pool areas, BOP transportation systems and tree cart arrangements. Where emergency repairs are required to existing BOP or lift systems, ICON can carry out design checks, procure and fabricate parts, and install and commission the equipment.

Engineering and execution support for crane pedestal design, fabrication and installation, including offshore relocation of cranes to meet changing deck layout or operational requirements.

Design and supply of rated firewalls and blast walls for retrofitting to operating drilling rigs. Solutions are developed to be transported to the rig and installed while on location and operational, minimising disruption to drilling activities.

Design and delivery of interfaces for drilling, subsea, completions and well testing equipment onto the MODU.

Engineering support for temporary works, lifting arrangements and installation methodologies aligned with vessel capabilities.

Management of class society approval processes for MODU modifications, including liaison with verification bodies such as DNV and ABS. ICON’s offshore personnel have extensive experience supporting MODU inspections, class surveys and condition reporting.

Provision of offshore construction engineers, supervision, trades labour, and technical support to safely deliver modification scopes offshore.
