FLNG cooling

Less space and weight for FLNG cooling

On FLNGs temperature control is a critical but spaceconsuming application. Framo FLNG cooling systems combine open and closed loops, which allows both parts to be optimized and streamlined.

Cooling via the hull

FLNG cooling have traditionally been managed by large
conventional pumps, installed as topside modules. Today, however, there is a more compact and economical solution. Built with leading heat transfer technology, Framo FLNG cooling systems combine a closed thermal loop with an open loop, which leads to system-wide savings in space, weight and cost. Integrated with the hull, they replace topside pump modules with compact seawater lift pumps using the Framo cable-free concept.

Savings in two steps

Savings can be found in both the open and closed loops of these integrated Framo systems. In the open seawater loop, the pumps, filters and heat exchangers are configured to provide the right cooling or heating performance with the minimum amount of equipment. The effect this has on power consumption is negligible, yet it reduces weight by 25% and creates a 15–20% savings in CAPEX.

In the closed freshwater loop, compact cable-free electric submersible pumps replace the topside pump modules. These take up no space on deck and create equally dramatic weight savings.

Freeing up space and time

The total result is a massive reduction in both footprint and weight, which means less CAPEX, lower OPEX and space topside that can be used for other processes. In addition, the seamless system interface ensures easy access that reduces the time needed for maintenance work.
