The Multi Purpose Tower (MPT) was introduced to the market in the late 90’s. It is a box girder type mast which houses all the machinery inside. The MPT has the same functionality as a normal derrick but offers additional improved accessibility to the well centers. This accessibility and its improved handling procedures allow for a more efficient way of working.

The first MPT was installed on the Well Intervention Vessel Q4000 in 2001. Over the years, the MPT has evolved through several stages into the 2,400 Kips Dual Multi Purpose Tower (DMPT) that is now featured on drilling vessels Noble Globetrotter I and II. In new designs the capacity can be increased to 3,000 Kips.

The design of the DMPT allows for a radical change in handling pipe and equipment, increasing efficiency and safety. Different ways of handling will speed up the process dramatically, while having a welded structure with the majority of the equipment on the inside dramatically reduces the amount of potential dropped objects. The DMPT can be mounted on any drill ship and semi-submersible design.

As Huisman is convinced that this is the future of drilling, we built a new 90m high DMPT, capable of handling 55 m (180 ft) stands and 46 m (150 ft) riser and with the ability to simulate dynamical vessel movements, at the Huisman Schiedam quayside. This Huisman Innovation Tower (HIT) is used to demonstrate Huisman drilling equipment, to develop and test future equipment and systems and for the training of operators and Huisman staff.
