Abstract
A seafloor pump assembly is installed within a caisson that has an upper end for receiving a flow of fluid containing gas and liquid. The pump assembly is enclosed within a shroud that has an upper end that seals around the pump assembly and a lower end that is below the motor and is open. A separating device is connected to an upper end portion of the discharge pipe within the caisson. The separating device causes separation of gas from the flow containing gas and liquid to be enhanced prior to the flow reaching the operating liquid level in the caisson.
