Andritz maps drilling equipment decisions to the operational constraints of mines, energy fields, and process infrastructure. Every industry file begins with a formally captured duty envelope, converts site-specific inputs into a reviewed technical basis, and closes with a stamped equipment recommendation that references formation hardness, depth window, flush media, and planned intervention cadence. This structured approach is how operators working under ISO 45001, MSHA Part 56, and national mining codes keep equipment justification defensible during permitting, audit, and insurance review.
Production drilling, exploration, and brownfield fleet replacement with documented ground-condition assumptions. Typical scope covers 76-165 mm blasthole diameters, bench heights of 10-15 m, UCS ranges up to 250 MPa, and fleet utilisation targets above 82 percent. Deliverables include rotary-head torque curves, mast verticality tolerance, and dust-suppression compliance notes.
Equipment review paths for pad constraints, duty cycles, support utilities, and service access. Files address hook loads up to 250 t, mud circulation between 800 and 2,200 lpm, H2S-rated material selection per NACE MR0175, and winterised hydraulic packages certified for minus 40 C sustained operation on northern pads.
High-temperature drilling support where reliability evidence and controlled service planning matter. Design cases cover 180-260 C bottom-hole temperatures, casing programmes down to 4,500 m, high-temperature elastomer packages rated to 232 C continuous, and scavenger-pump skids matched to high-flashing brine circuits under API 610 BB5 duty.
Equipment and service decisions for access-limited process sites with strict shutdown windows. Scope includes 72-hour outage-boxed overhauls, modular skid inserts under 2.4 m transport height, electrical interlocks compliant with IEC 61508 SIL-2, and documented LOTO handover folders aligned with the plant permit-to-work system.
