Synopsis

Marine installations in the oil & gas industry are high risk structures because not only subject to hazardous and flammable hydrocarbon materials but also to hostile marine environmental loadings most of which were unpredictable in terms of magnitude scale. Hence, appropriate input parameters for use in analysis should be selected in optimizing the design. The installations are also to be designed to a unique load combination. Besides process plant aspects and inherent hazard factors by plant activity, the design must account for the criteria during in-service and pre-service (before commissioning) conditions; corrosion caused by seawater; and high content of C02 and sulphur in crude oils add to the cost and complexity of maintenance work offshore. Therefore, the design must be kept as simple as possible with the maximum throughput every time without sacrificing the safety aspects.
The float-over methodology allows Superstructure (Topsides) to be fabricated with most equipment ready for commissioning that not only reduces offshore hook-up work and standby time but also removes the need for heavy lift barge and its limitation which will significantly reduce offshore installation cost.

A brief approach in accounting for global design possible events in terms structural and naval architectural aspects will be discussed. These design variables considerations and underlying engineering parameters will be assessed in meeting installation minimum performance within budget constraints, time schedule, safety and functionality.

Faizal Mahamud studied in Civil Engineering (Civil & Structural) at UKM has 12 years of experience in the oil & gas industry specifically in Structural engineering.  He has extensive experience in performing FEED and detail design that relate to float-over, FPSO and Offshore Fixed Platform analysis. He started career as Structural Engineer with RNZ Integrated (KL) and had involved in projects that related to float-over methodology. At present he is with Aker Solutions as Senior Structural Engineer.

Ir. Affiq Aiman Bin Aminuddin studied in Marine Engineering (Mechanical) at UTM has 11 years of  experience in the oil & gas industry with experience ranging from FEED, bid preparation, detail design, fabrication, commissioning and site operation both domestic and international projects. Started careers as Naval Architect with Boustead Heavy Industries; involved in preparing technical specification and navy vessel construction. Later, joined Sime Darby Engineering as Project Engineer for the construction of derrick lay barge and anchor handling tugs, then joined ALE Heavy Lift as Naval Architect and specialist for marine operations in load-out and float-off. At present he is with Aker Solutions as Naval Architect.
