Wärtsilä has signed a five-year technical management and services agreement with Songa Offshore for four Cat-D type semi-submersible drilling rigs operating in the North Sea.

With this agreement, Songa Offshore ensures optimal performance of the drilling rigs by using Wärtsilä engines and thrusters on-board the drilling rigs that operate in extremely harsh conditions.

Under the agreement, Wärtsilä will provide dynamic maintenance planning and inspections, real-time condition monitoring of engines and thrusters, as well as equipment analysis reports.

Better maintenance scheduling is expected to improve cost-efficiency.

Wärtsilä Norway sales director Cato Esperø said: "We are very excited about this first long-term service agreement with Songa Offshore.

"With our expertise, we ensure that Songa Offshore’s rigs can reach their full performance in the harsh environment of the North Atlantic basin."

The agreement includes Songa Equinox, Songa Encourage, Songa Endurance and Songa Enabler rigs.

Each of these offshore rigs carries six Wärtsilä 32 engines.

Two among them have six Wärtsilä FS3500 steerable thrusters, while the other two are equipped with six Wärtsilä FS3510 steerable thrusters.

The rig type is able to perform year-round drilling, completion, testing and intervention operations in extreme weather conditions.

Songa Offshore head of asset maintenance Geir Arne Rolland said: “The agreement helps Songa Offshore maximise the availability of the Wärtsilä engines and thrusters on our four Cat-D rigs.

“Reliability of the engines and thrusters, as well as real-time knowledge of the actual condition of the equipment are crucial to our operations, and this is also a part of Songa Offshore’s Class on Location strategy and continuous class project.”

"We ensure that Songa Offshore’s rigs can reach their full performance in the harsh environment of the North Atlantic basin."

The contract also covers Wärtsilä’s digital services.

The condition-based maintenance (CBM) system enables Wärtsilä to monitor performance of the Wärtsilä 32 engines installed on the rigs continuously.

The procured data is evaluated by Wärtsilä to determine service and maintenance needs.

Furthermore, the agreement includes the Wärtsilä Propulsion Condition Monitoring Service (PCMS).

PCMS provides customers with real-time advice and periodic reports about the steerable thrusters. The information is also useful for efficient maintenance planning.
