Abstract

Today the newest frontier in oil & gas exploration, drilling and production industries is the Oil and Gas Subsea Industry. Oil and gas fields reside beneath many inland waters and offshore areas around the world. Subsea oil & gas production equipment and systems can range in complexity from a single satellite well with a flow-line linked to a fixed platform, FPSO or an onshore installation, to several wells on a template or clustered connected to a manifold via a rigid spool. The proposed study focuses on developing a risk assessment and risk management tool that can be used by the decision maker in the field to address the risks involving the different subsea rigid spool operations. This includes site integration tests, different phases of the logistics operations to get these spools from their test facility to their offshore fields, and the deployment and installation operations carried out in their designated locations in the subsea fields. This study attempts to identify and integrate the risks in each operational step and give a clear account of the consequences involved ,the effects of such risks on the project as whole showing the true cost of such risks and also gives the tools to reduce these risks to as low as reasonably practical.
