The BT-220IU Wind Installaltion Units with the 2.600 mT Heavy Lift Crane and a very high hook height, by that capable of installing the largest Next Generation Wind Turbines onto the highest WTG towers, including Floating WTG at a in or nearshore dedicated location
Furthermore, the Unit is also capable of installing XXL Wind Turbine Foundations
The Units can also be used for e.g. Installation and Commissioning of Transformer Substations.
WELL INTERVENTION, WELL STIMULATION, P&A AND DECOMMISSIONING
Well Intervention and Well Stimulations activities are today typically done by drilling rigs and stimulation ships.
The BT-260WIS Unit design combines these operations, make the operation safer by not execute the intervention/stimulation connected to the well in floating condition, which e.g. a well stimulation ship will do
A Cessation project typically include P&A of wells, pre-work for Decommissioning and the Decommission work where the platform is partly of fully removed
Unit designs, such as the BT-260/380WIS, is tailormade for these combined activities including if possible SIMOPS of P&A and prep-work for Decommissioning. Modules, Jackets or part of them can be lifted on to the PAU deck for further processing into piece medium or piece small. Alternativity, modules or Jackets/sections can be lifted directly onto a vessel or barge deck for transport back to shore
The unit’s WOR which would have the same design capacities as for the BT-260, can perform Heavy Work Over operations including:
- Side-tracks (out to 15,000’)
- ESP change out
- Clean-out of existing casing/tubing
- Milling operations
TENDER ASSIST AND MODULAR WORK OVER RIG PROJECTS
If there for any reason is no possibility to perform well work with the Cantilever, a Modular Drilling Rig can be lifted onboard to the host platform. The PAU rig can then serve as a Tender Assist Unit for the drilling or well operation. The unit can cater for large quantities of cement, mud and other liquids etc. to support the operation.
OIM Ltd. Jack-Up unit designs can provide flexible accommodation and heavy lift construction support for Hook-Up and Commissioning activities during installation of new Jackets and Topsides
The Unit design allow for accommodation of large number of construction personnel and by being a Jack-Up have 100% up-time during all weather conditions unlike semi-submersible accommodation and construction support rigs.
OIM Ltd. Unit designs are flexible solutions, which also include removable cantilever, providing large free deck space which can be used for temporary storage of equipment and modules. The Heavy Lift Crane can install add-on modules etc. The Unit can, with it’s permanent Living Quarter accommodate more than the typical number of personnel which are required for large Brownfield projects
SUBSEA WELL INTERVENTION, STIMULATION, P&A AND DECOMMISSIONING
The units can perform subsea well intervention, stimulation, and P&A work. In the same operation cut the Wellhead Conductor and Casing etc., and as part of the same operation remove the Wellhead template avoiding mobilisation of additional vessels for the subsea decommissioning work
The Heavy Lift Crane can also install or remove subsea structure at max operational water depth for the Unit
