Marine Drilling Rig ARB20-18
Nowadays, offshore engineering surveys are practically impossible without geotechnical drilling. However, depth and type of studies substantially vary depending on the project targets. Sometimes the project budget does not permit to use specialized drilling vessels that are quite expensive. At the same time economically feasible onshore drilling rigs, installed on pontoons can not be used as well as they are not powerful enough to ensure high quality of studies. Our solution for that - a mobile drilling rig!
Main Features
Mobility
Built for shipment in ISO sea freight containers
Autonomy
Energy independent from the vessel
Versatility
Can work from cantilever or through the moonpool
Lightweight
Shipping weight of complete system less than 100 metric ton
Main Capabilities
The concept of a mobile marine drilling rig ARB 20-18 built by the Singapore company "Armada Rig Builders" meets the most diverse and strict operational requirements, simultaneously satisfying initially incompatible survey parameters.
It is mighty enough not only to drill to a depth of 700 m and take samples by sophisticated sampling devices but to perform a full set of well tests including CPT along the entire borehole.
Geotechnical and pilot boreholes
24-ton hook load capable of up to 350 meters of API drill pipe
Sampling
Soil sampling with diameter up to 107 mm
CPT
Designed to deploy 3rd party hydraulic push sampling and in-situ testing tools
Installation Options
- When ARB 20-18 is installed on a specialized RV it can become a multipurpose and mobile survey tool remaining at the same time economically efficient due to a relatively low cost of drilling
- Installation of the drilling rig on a non-self-propelled barge provides a feasible production at depth of 2 m at minimum draft
- ARB 20-18 installed on ice-class ships and icebreakers can work in the remote Arctic zones, inaccessible to the majority of specialized drilling vessels
Vessel
Any suitable vessel
Jack-up
For shallow water operations
Icebreaker
For work in harsh Arctic environment
Safety
The drilling rig operation is environmentally safe. It is based on a closed cycle of drilling mud use. All units and components of ARB 20-18 have TUV, DNV certificates. The John Deer engines are compliant with Euro 5 standard.
