3 BISSO MARINE, LLC is proud to introduce the. Purchased in 2015, the was purpose built as a very stable open ocean pipelay asset capable of performing pipelay operations in diverse geographical environments. The barge has operated worldwide and has achieved successes in currents in excess of 7 kts (3.6 m/s) and performed continuous pipelay operations into seas greater than 10 ft (3.28 m). The operational water depth limitation is approximately 1,000 feet, but will vary by project.
