Paper Title: Value Proposition of Offshore Steel Structure Decommissioning

Speaker: Ahmad Rizal Bin Abdul Rahman

Majority Offshore Platforms has always been installed using the conventional crane barge. This has resulted in a significant installation costs as the mobilization and charter rates for the vessel is very exorbitant. Supporting the innovation agenda in an effort to better control project costs, PETRONAS has recently embarked on the rig-installed platforms, i.e. offshore platforms that can be installed using Jack-Up Rig (JU). In the O&G industry, JU is predominantly used to drill oil/gas wells. However, with some modification, these JU can be utilized as the main vessel to install offshore structures, both jacket and topsides. This advancement has been around for quite sometimes in the industry, but was not quite regularly exploited in this part of the world. Recently, Petronas Carigali Sdn Bhd, a full subsidiary of PETRONAS, Malaysia’s National Oil Company has embarked in adopting this concept for a new platform in D28 field in Sarawak Waters. This platform was successfully engineered, fabricated and installed using the JU, and eventually achieved 1st Oil production, a major milestone, on 26 November 2018. This project has exemplified to the industry that JU-installed platform is possible in this part of the world, with significant cost savings, contributing to a better economics for the project. This paper will mainly discuss on the pre-requisites of JU-installed platforms, case for change, concept select and potential value creation to the overall project.
