Abstract: Telescopic containers (10, 100) for containing fluids associated with hydrocarbon production are disclosed. Such containers (10, 100) may comprise a lower container section (12), an upper container section (14) moveable between a retracted position and an extended position in a telescopic manner relative to the lower container section (12) and a sealing member (40, 50). The sealing member (40, 50) prevents or substantially prevents leakage of fluid from the container (10, 100) between the upper container section (14) and the lower container section (12). The lower container section (12) may define an elongated and/or multi-sided shape.
