The vessel is also able to submerge 13.5m for loading and discharge of deeper draft drilling rigs and floating production facilities.

A Kongsberg DP-II system is fully integrated with two tunnel thrusters at the bow and three fully-revolving main azimuth thrusters at the stern.

With 19,000 kW of power, the vessel is expected to transit at a speeds up to 14 knots.

The vessel is currently on schedule to be delivered in the fourth quarter of this year.

Houston-based, ZOMC is a joint venture between ZPMC Offshore Services Group and OffshoreTech, that provides the oil and gas market with access to niche vessels for execution of a broad range of complex offshore logistics projects serving client needs through the full lifecycle of a facility from greenfield installation, brownfield modifications, and ultimately decommissioning.
