The hotel will open on September 14 with the contract for its operation running through to April next year although there are options for an extension.
Earlier this year Global, majority owned by Ross County chairman Roy McGregor and his family, announced plans for £37 million of development work to expand the quay at Nigg to help position it as a major hub for oil and gas and renewable energy work.
David Morrison, chairman of Snoozebox, said: "We are pleased to be working with Global Energy Group at Nigg Energy Park. The relationship marks Snoozebox's entry into this dynamic sector and provides the potential for further growth."
Analysts at Panmure Gordon believe the deal is a positive step for Snoozebox as it is expected to profitably deploy rooms over the quieter winter months.
The added: "This is clearly encouraging progress, broadening Snoozebox's reach and providing an entry point and relationship in a sector with obvious demand for temporary, but long-term, accommodation requirements."
Global has already spent around £14m upgrading Nigg since acquiring it in October 2011.
Snoozebox recently had one of its hotels on Calton Road in Edinburgh for the August festivals season.
The temporary hotels have also been used at events such as the British Grand Prix at Silverstone and the Glastonbury music festival.
