Collaboration To Expand Geographic Presence

An up-and-coming name in the subsea sector has successfully collaborated with a leading provider of data collection to complete their first joint project in the south Caribbean Sea.

Sulmara Subsea recently joined forces with XOCEAN to deliver a seabed survey off the coast of Aruba on behalf of SeaDrill using an XO-450 Unmanned Surface Vessel (USV).

Operating 15km off Barcadera Port on the Western side of Aruba, the USV completed the 26km2 seafloor survey in 70m of water using high resolution multibeam. The objectives were to identify any seafloor features and classify the seabed to allow moorings to be safely installed.

Throughout the mission, a team combining Sulmara and XOCEAN USV pilots, surveyors and data processors monitored performance to ensure safe operation of the vessel and quality of data collected. Use of unmanned systems holds many benefits, including safety due to operators remaining onshore and efficiency thanks to 24/7 operations. XOCEAN’s USVs have a negligible carbon footprint and all other emissions are offset, resulting in a fully carbon neutral operation.

“With COVID-19 lockdown in place across the Caribbean, our client needed a remote solution on this time-critical survey. Time previously spent with XOCEAN on the potential benefits of collaboration meant both companies were able to react quickly and efficiently to meet SeaDrill’s needs.”
