MELBOURNE, AustraliaDNV GL has developed a new unmanned floating LNG concept.

Called “Solitude,” the concept demonstrates how technological advances – most of the technology already within reach - can be combined to offer 20% reduction in annual opex, only adding a few percent increase in capex, and at the same time increase the overall safety.

Equipment throughout the FLNG concept would be modularized and monitored from shore with much of the routine maintenance and fault correction carried out by self-programming autonomous inspection and maintenance units (robots). The topsides would have a system of rails that run along each process train, providing these robots with access to all the equipment.

Wireless sensor networks act as eyes, ears and noses, feeding information to a condition monitoring system that overseas fault detection, proactive maintenance, and repair planning.

“While Solitude is a holistic concept, many of its solutions can be implemented independently – and some are already available today. These projects are our way of thinking out loud. Our aim is to present high-level concepts that can form a basis for discussion and be further developed in collaboration with the industry. We see Solitude as a new opportunity for the future,” saidElisabeth Tørstad, CEO of DNV GL Oil & Gas.
