But things are changing fast.
"The town is really growing a lot ... especially in the last year," says Vijay Handa, cluster general manager of the City Hotel Duqm, one of three new hotel chains catering to an influx of businesspeople.
"In the next four or five years, it's going to see even more people coming, with more building and more opportunity," he adds.
Duqm is earmarked as the site of a vast new container port, refinery and industrial zone that, it is hoped, will help move the country away from dependence on oil revenues.
A new international airport, tourist resort, fishing harbor and residential zone for a potential 111,000 people are also key components of the Duqm masterplan, which was initiated in 2011
Population statistics for the town are hard to come by. But Oman's National Center
for Statistics and Information reports
that the population of the sparsely populated Wilayat ad Duqm province, which includes the town, doubled from around 6,000, in 2011, to just under 12,000, in 2017.
According to Stephen Thomas, CEO of Omani facilities management firm Renaissance Services -- which recently opened a $197 million housing facility in the town capable of accommodating 16,900 workers -- Duqm will become a "great city."
"Already, you can see the momentum coming," he says. "You can see the blueprint for this city."
