MPU Heavy Lifter (MPU-HL) is a trademark for the floating U-shaped concrete unit developed by MPU
Enterprise AS. MPU is short for Multi Purpose Unit and reflects that the unit is
intended for multiple uses such as removal of abandoned offshore structures, installation of new or
refurbished offshore structures, floating production, floating storage, oil spill recovery unit, support
structure for offshore oil and gas exploration facilities and floating dock.
The MPU-HL is equipped with steel lifting frames and heavy-duty strand jacks for single lift of large
topsides and jacket structures. A unique flushing system ensures a rapid de-ballasting and increase of
freeboard. The geometry of the concrete hull is based on extensive tank testing which ensures excellent
motion characteristics. The lifting area has a clear space of 45 x 63 meters allowing for removal of
large structures. The lifting frames are hinged at the attachment points on top of longitudinal pontoons.
