The American Bureau of Shipping (ABS) has announced it will classify a series of self-elevating drilling units (SEDUs) for Bahrain-based Silver Eagle Global.

According to Silver Eagle, the self-propelled design of the SEDUs can handle work at greater water depths. These SEDU units also work in difficult environments.

The SEDU series uses a modular cantilever and a high-speed jacking system.

Technical services provider ABS said it will initially classify two vessels with an option for two additional vessels. It expects to build a series of similar vessels after the initial order.

Global Offshore senior vice-president Matthew Tremblay said: “These unique units offer the flexibility to adapt to the mission and payload. The large deck and cantilever are innovative design features, while self-propulsion and the four legs allows the vessel to get on the job site independently.”

Silver Eagle has awarded a contract to PetroVietnam Marine Shipyard to build the vessels for an undisclosed sum.

Silver Eagle executive chairman Ronald Sanders said: “We believe this design will provide a cost-effective solution for the offshore energy industry in all cycles of commodity prices. It gives me a great sense of pride to see this vessel contribute to the evolutionary and revolutionary worldwide offshore oil and gas service industry.

“We are extremely pleased to be working with ABS to class the vessels and PetroVietnam Marine Shipyard (PVMS) to build the Silver Eagle SEDU’s.”
