Wärtsilä has signed a long-term agreement to optimise thruster maintenance within Transocean‘s fleet.

The 13-year agreement carried out with minimal interruptions to operations. It will extend the service intervals of thrusters in order to significantly minimise dry-docking costs.

During the agreement period, all six to eight thrusters in each of five semi-submersible rigs and one drillship will be overhauled.

The partners will leverage Wärtsilä’s Propulsion Condition Monitoring Service (PCMS) developed to capture performance data from the thrusters, which will be delivered to a Wärtsilä Expertise Centre for analysis.

Collected data will then be examined by service experts to determine a feasible schedule for the maintenance of each piece of equipment depending on their existing condition.

“Collected data will then be examined by service experts to determine a feasible schedule for truster maintenance.”

Installation of the PCMS, spare parts and personnel are also covered under the agreement.

Wärtsilä sales for offshore and marine general manager Kourtney Dever said: “We are deepening our co-operation with Transocean. As the oil and gas market turns around, we will be there every step of the way to support Transocean with efficient solutions for its fleet.

“By improving thruster condition and enhancing the efficiency of maintenance, we show our commitment to providing high-performance throughout the equipment lifecycle.”

In February, Wärtsilä signed a similar 25-year agreement for thruster maintenance strategy across three semi-submersible rigs and four drillships of Maersk Drilling.

The joint strategy by Wärtsilä and Maersk involves planning procedures for thruster maintenance, services and equipment exchange in case of emergency.
