IEM Shout Out – 2019-06 Talk on “Environmental Forces Effect on Structure Decommissioning Operation”

My technical division will be hosting a talk on the 22nd June 2019. It is worth 2 CPD points, and held at Wisma IEM. The talk will be presented by yours truly, so come and fill seats, especially since I am giving it during the fasting month.

Recently, aging, abandoned and unused offshore oil and gas platforms, subsea completion and related structures, with more than 600 projects are planned to be decommissioned within 5 years period. Studies made recently expects expenditure on offshore decommissioning projects to increase from approximately $2.4 billion in 2015 to &13 billion-per-year by 2040, a major increase of 540%. The challenges related to lifting and lowering technology is the weight of the structures to be installed, which combined with the dynamic response, can exceed the capacity of the lifting system. The harsh environment is acknowledged as the greatest challenge that should be carefully considered. Typically, such analysis on the structure at the splash zone governs the expected major loadings in the hoisting system and in turn the allowable sea state since the water particle kinematics is larger in the splash zone and computationally simulated to predict the total motion. In this study, the DNV Recommended Practice for Modelling and Analysis of Marine Operation (DNV-RP-H103, April 2009) is used as guidelines with emphasis on the hydrodynamic coefficients and analysis methodology for the splash zone down crossing analysis, which is considered to be the operation limiting criteria.

Ir. Mohd Fakhruddin, an energetic engineer with years of experience working in offshore, oil and gas engineering, focusing on transportation installation offshore structures. Graduated from Australian Maritime College, AMC in Bachelor of Engineering (Marine and Offshore System) in 2011, involved in the oil and gas industry as CFD Project Engineer at BMT Fluid Mechanics Ltd., and continues his career progression as Naval Architect at Sapura Energy in 2013 to 2019.Currently working as Subsea Installation Engineer at McDermott APAC. In 2015, he continues his study in Master of Science, UMT as a part time student, graduated on November 2018. Dedicated and experienced Naval Architect/Subsea Engineer in all phases of engineering operations related to hydrodynamic problems.
