The invention discloses an oily water collecting system for a deepwater semi-submersible type production oil storage platform. The oily water collecting system for the deepwater semi-submersible type production oil storage platform comprises a discharge main manifold, a discharge tank, a discharge pump and a dirty oil cabin, the discharge main pipe manifold is connected with the upper-layer deck and the lower-layer deck, oily water of the upper-layer deck and the lower-layer deck converges to the dirty oil tank along the discharge main pipe, and the dirty oil tank is arranged in a stand column of the ship body; a discharge tank and a discharge pump are arranged between the lower deck and the discharge main manifold, and oily water flows into the discharge main manifold along the discharge tank through the discharge pump. According to the oily water collecting system for the deepwater semi-submersible production oil storage platform, the situation that in order to enable the open drainage main pipe to be connected into the dirty oil tank, perforating operation needs to be conducted on the side face of a structural stand column where the dirty oil tank is located is avoided, and the integrity of the platform structural stand column and the safety of a lower floating body structure are guaranteed; and meanwhile, the discharging main manifold can be controlled within the range close to the lower deck, and the risk that the discharging main manifold is slapped and damaged by waves due to the fact that the position of the discharging main manifold is too low is avoided.
本发明公开了一种深水半潜式生产储油平台污油水收集系统,该深水半潜式生产储油平台污油水收集系统包括排放主管汇、开排罐、开排泵和污油舱;排放主管汇与上层甲板和下层甲板连接,上层甲板和下层甲板的污油水沿排放主管汇流至污油舱,污油舱设置在船体的立柱中;下层甲板与排放主管汇之间设有开排罐和开排泵,污油水沿开排罐经开排泵流入排放主管汇。本发明提供的深水半潜式生产储油平台污油水收集系统避免了为使开排主管汇接入污油舱,需对污油舱所在结构立柱侧面进行的穿孔作业,保证了平台结构立柱的完整性和下浮体结构的安全;同时能够将开排主管汇控制在离下甲板较近的范围内,避免了由于开排主管汇位置过低而被波浪拍击破坏的风险。
