Subsea technology and data company Ocean Infinity has secured a contract from ExxonMobil to supply autonomous underwater vehicles (AUVs).

The AUVs will be used for geophysical and geotechnical data gathering in the Stabroek block offshore Guyana.

Under the contract, Ocean Infinity will deploy various high-resolution AUVs across an area of about 3,100km². The vehicles will operate simultaneously in water depths ranging from 70m to 2,150m.

In a press release, the company said simultaneous operation made operations more sustaianable.

Ocean Infinity CCO Paul Helmore said: “We are very pleased to be supporting ExxonMobil in Guyana with our advanced data acquisition technology, to help them identify and evaluate seabed conditions on the Stabroek Block.

“Our innovative use of sustainable, low-impact technology will support their development of the acreage and ultimately [help] to meet the region’s growing energy demand.”

ExxonMobil started Guyana oil and gas exploration activities in 2008. Oil in the Stabroek block was first discovered with the drilling of the Liza-1 well in May 2015.

Ocean Infinity is developing UAV batteries, which can tolerate pressures up to a 6,000m depth. The batteries were developed with Kraken Robotics and testing was announced in November. Executives said they could power UAVs for up to four days without recharge.

According to Ocean Infinity, this increases the possible survey range for each AUV to nearly 700km.

Last month, Ocean Infinity launched a new marine technology and data company Armada. The new subsidiary will operate a fleet of 15 unmanned surface robots, equipped to survey pipelines and map ocean data.

In December last year, Ocean Infinity secured a contract from Total E&P Angola to carry out a 2D seismic survey offshore Angola.
