| Abstract | Currently, Thailand oil and gas industry provi de over two hundred fixed steel platforms. The installations were normally attended with more activities of offshore vessels. The most important incidents in the operation between ship and platform were ship-collision incidents that occurred frequently in the Gulf of Thailand. The incide nts were reported that many collision cases have been involved by attendant vessels. Ship-platform collision is the rare phenomena in offshore oil and gas industry. There have been many incidents reported in last 30 years especially in the North Sea. Many range of damages occurred affecting to the platform inte grity that normally described as the minor damage. However, the severed incidents in Mumbai high Nort h platform (2005) indicated that the riser is one of the important components that have to be protected against the collision as much as possible. This thesis has performed the riser protection against the collision from attendant vessel in the Gulf of Thailand. The study is to apply a ll existing methodology and relevant data from the North Sea including the informal data fr om personal interview in oil and gas company of Thailand. However, this study tries to es tablish the methodology for existing frequency estimating model form Det Norske Veritas ( DNV) to apply in the Gulf of Thailand. The risks of attendant vessel - riser collision of three steel fixed platforms were assessed by the modification of DNV’s methodology includi ng the information from the North Sea. Three frequency estimating models were established to calculate the collision frequencies based on the available information from the North Sea. These models have different approaching directional data that the disc ussion and comparison of the results were performed. The results fr om these models tend to be prov ided in high risk due to the insufficient data in the Gulf of Thailand. The frequency estimating models has been indicated that there is no n eed to perform in more comp licated models due to high uncertainty and insignificant different in the results. |
