OML 100 As-Built Design and upgrade planning

Carried out Site visits to the offshore oil block of OML 100 for Laser Scanning and assessing the condition of Platform Structures, piping and equipment on the platforms covering Odudu, Afia, Ime, and Edikan platforms. The scan data was Used to generate an as build model which was subsequently used to carry out As-build design of the existing platforms as the design documents of the platforms could not be found in the archives. The platforms was inspected and assessed for Upgrade repairs planning by Identification of Piping spools and lines to be revamped by Isolation, partial/total shutdown, online repair, cold or hot work. Designs of piping spools and structural steel works was carried out for all piping, Piping supports and structures that was due for sectional replacement, same for corroded Equipment like pumps. Man hour estimation and cost estimation for prefabrication and field installation was carried out, together with a draft work schedule for construction phase.
