Expert Corrosion Design Basis Memorandum (E-CDBM)-Corrosion Digital Solution at Your Fingertips Abstract The objective of the paper is to communicate on the development and commissioned of Web-Based Online Expert Corrosion Design Basis Memorandum (E-CDBM), an online solution to accelerate, simplify &amp; standardize CDBM development which has been piloted for Upstream Wellhead Platforms and Pipelines. CDBM is a project key document consisting of the design basis of material selection, corrosion control, testing and monitoring which is typically developed and approved manually. This digitalization initiative will take CDBM to a next level in designing corrosion features for upstream facilities in line with COMPANY aspiration of going digital. Phase 1 web based E-CDBM consists of eight sections which are General Input, Process Data and Design Basis, Internal Corrosion Assessment, External Corrosion Assessment, Materials Option, Corrosion Control, Corrosion Testing &amp; Monitoring, and Asset Register. Under Phase 2 enhancement, other modules to address Central Processing Platform (CPP), Subsea and Deepwater, Carbon Capture&amp; Storage (CCUS), Renewable Energy (Offshore Wind Turbine), Well’s casing and tubing, Underwater jacket anode optimization, Lesson Learn and Loss of Primary Containment (LOPC) Module as well as Cost Engineering Module. Prior to the development of E-CDBM website, the first step is developing technical requirements and business logic spreadsheets. Eleven (11) internal and nine (9) external degradation mechanisms with regards to upstream facilities has been considered and the option for materials and corrosion control, testing and monitoring tools were populated. The user will be able to cross referred to the Lesson Learn and Loss of Primary Containment (LOPC) module to check on the material performance based on actual operator’s experience. On top of that, for an economical material selection, user can calculate Life Cycle Cost (LCC) that considered Operational Expenditure (OPEX) as well as (CAPEX) from Cost Engineering Module that developed in collaboration with COMPANY Cost Engineering Department and Operation. E-CDBM will be connected to email for notification and the programming will enable online reports, comments, review, and approval. All the information will be stored in one place with a cloud system for easy access and retrieval. E-CDBM will enable data collection and future machine learning adaption where trending and data comparison can easily be conducted. E-CDBM will have the following features: (i)Stringent quality control, standardize format and fast report generation, (ii) Consistent and supervised technical approach and recommendation, (iii) Fit for purpose material selection, corrosion control, testing and monitoring, (iv) Incorporation of lesson learns and best practices from different project phase, (v) Effective tracking and approval for data changes &amp; deviation and (vi) Easy accessibility and secure online database with cloud system (vii) Integration to email server and Project Engineering Data Management System. From this E-CDBM initiative, work process simplification to develop CDBM will be achieved and resulting in 30% potential cost and manhour saving. In addition, a consistent technical approach and recommendation through E-CDBM will potentially incur cost avoidance by having fit-for-purpose materials, corrosion control, testing and monitoring tools as well as Price of Non-Conformance (PONC) avoidance for unplanned facilities modification/replacement. In summary, E-CDBM is an opportunity for COMPANY to develop inhouse capability and indirectly will raise oil and gas technology profile.
