MHWirth’s flexible base of field-proven drilling equipment for jackups is designed for medium to heavy-duty vessels and fits to all market-leading hulls.

For more than three decades, MHWirth’s jackup con-cepts have successfully performed drilling, field develop-ment and workover operations worldwide. Our concepts have been proven in harsh winter operations such as in the North Sea, and they also operate efficiently in benign waters with high temperatures.

MHWirth offers solutions for all market-leading hull de-signs with a strong focus on efficient operations, mate-rial handling, simultaneous operations and redundant designs.

Our experienced and skilled engineering service tailor-make solutions for your special project requirements and they assist yard and vessel designers according to their needs.

Based on our extensive field experience, our engineering design fully meets NORSOK and HSSE requirements.

All MHWirth drilling packages meet the highest HSSE stan-dards and are delivered in accordance to with all relevant certifications such as ABS, DNV, CDS, API and more.

Through advanced technology, we are able to provide training that realistically matches the equipment and the challenges on a rig. Our full-scale simulators provide a unique opportunity to train in a rig-specific, realistic and safe environment.

The following basic operations can be executed with our equipment packages:■ Drilling production, injection, exploration and relief wells■ Batch drilling■ Completion of subsea wells■ Intervention and maintenance of subsea wells■ Wireline and coiled tubing operations■ Well-testing and clean-up operations■ Killing of wells

Jackups

■ Flexible solutions to suit project requirements and hull designs

■ We take full system and functional responsibility for the entire drilling package, including the mud system and arrangements for third party service equipment

■ Integrated drilling control and monitoring system including DrillView™ system, enabling condition based maintenance

■ We use simulators in the design phase to optimize operations and for training
