Maersk Drilling, NOV team up to lower rig maintenance costs

Offshore staff

COPENHAGEN, Denmark Maersk Drilling and National Oilwell Varco have entered into a five-year partnership to improve maintenance predictability for drilling equipment.

The partnership aims to implement a new maintenance mind-set which will increase value for customers by minimizing operational down time while lowering maintenance costs.

The agreement covers Maersk Drilling’s three deepwater D-class semisubmersibles as well as the four ultra-deepwater V-class drillships.

Until now, major overhaul of drilling equipment has been carried out with five-year intervals as part of the special periodic surveys at quay side. Through this partnership agreement, Maersk Drilling will switch to a condition-based maintenance strategy, where overhaul and repairs will, to the extent possible, be carried out as rolling maintenance while the unit is operating.

Frederik Smidth, chief technical officer of Maersk Drilling, said: “This is a new way of looking at maintenance, and our ultimate goal is to eliminate the need for quay side SPS yard stays every five years, while still ensuring the highest level of safety and operational efficiency possible...

“By partnering up with National Oilwell Varco, we aim at achieving a higher level of maintenance predictability, hereby reducing the cash-flow impact from maintenance activities – ultimately resulting in less down time for our customers. Collecting, analyzing, and sharing data as well as detailed knowledge about the equipment will be key in succeeding, which is why we believe a long-term partnership is a must.”

As part of the agreement, NOV will establish a dedicated team which can assist Maersk Drilling’s rigs when needed. The team can be deployed instantly if an urgent task arises or if a window of opportunity opens in which the crew needs assistance with a major overhaul job. For example, this could be installation and start-up of a new top drive, while less time consuming maintenance tasks may only require parts and instructions to be shipped to the rig for the crew to handle.

When needed and where circumstances allow, equipment will be replaced and sent onshore for a complete overhaul to minimize interference on the rig. Following the overhaul, the equipment will return to service on one of the sister rigs with all the latest safety and operational upgrades in place.
