Abstract: A case is provided for a gas turbine engine. The case includes a wall defining a through-hole. The case also includes first and second pockets adjacent to, and on opposite sides, of the through hole. A method of reducing stress in a case of a gas turbine engine is also provided that includes reducing stress about a through-hole by providing a concavity on each side of the through-hole.

Abstract: A liquefied natural gas compression system includes: a first gas turbine that drives a rotary machine; a first steam boiler including a first heat recovery steam generator that recovers heat from exhaust gas from the first gas turbine; a first steam turbine that drives a first refrigerant compressor; a common header steam line through which steam from the first steam boiler flows to an inlet of the first steam turbine; an auxiliary steam line; and a letdown valve that connects the common header steam line to the auxiliary steam line and that opens in response to pressure of the common header steam line exceeding a predetermined threshold value.
