Geothermal Equipment Cases: H2S, CO2, NACE, UN 2935

A Schlumberger MWD (Measurement While Drilling) tool ($50,000-$200,000) shipped from a geothermal equipment OEM facility to a geothermal drilling site arrived with a damaged pressure sensor connector. The cause? A standard wooden crate with 25mm of loose-fill polystyrene that shifted during road transport over 400km of highways and local roads, allowing the 25kg MWD tool unit to move 15mm inside the crate and impact the crate wall during a 12g handling drop at the geothermal drilling site loading dock. The repair required a replacement pressure sensor connector ($2,000), a full re-testing of the MWD tool system ($5,000 in engineering time), and a 2-day delay in the geothermal drilling site’s equipment installation schedule. The geothermal drilling site’s delay cost was $10,000 per day (a typical geothermal drilling site has $5,000-$30,000 per day in delay costs for equipment installation downtime, including labor, equipment rental, and drilling schedule delays)—so the total cost of that damaged pressure sensor connector was $27,000.

Geothermal industry equipment spans the entire production system: from drilling equipment (MWD tools, LWD tools, drilling equipment controllers, drilling equipment sensors) that provide drilling equipment capabilities, to well logging instruments (gamma ray tools, resistivity tools, well logging instrument controllers, well logging instrument sensors) that provide well logging instrument capabilities, to reservoir characterization equipment (geophysics tools, geochemistry tools, reservoir characterization equipment controllers, reservoir characterization equipment sensors) that provide reservoir characterization equipment capabilities, to power plant equipment (turbines, generators, power plant equipment controllers, power plant equipment sensors) that provide power plant equipment capabilities, to environmental and process monitoring equipment (H2S monitors, CO2 monitors, environmental and process monitoring equipment controllers, environmental and process monitoring equipment sensors) that provide environmental and process monitoring equipment capabilities. What unites them is that every piece of equipment is part of a system where a single failure can cause a geothermal equipment installation outage (which can cost $5,000-$30,000 per day for geothermal operations), a safety issue (from equipment malfunction, which can cause geothermal accidents or worker injury), or in extreme cases, a geothermal equipment recall (which can cost $1,000,000-$100,000,000 for geothermal equipment companies). The transit case isn’t packaging—it’s the first line of defense against equipment damage during transport, and it must be specified to the same engineering rigor as the equipment it protects.

Regulatory Framework: H2S, CO2, NACE, UN 2935, and Geothermal Standards

Geothermal equipment transport cases must support compliance with a complex web of standards. For hydrogen sulfide, H2S (Hydrogen Sulfide) specifies hydrogen sulfide requirements for geothermal equipment, and the transit case must protect geothermal equipment from H2S corrosion during transport (including H2S-resistant materials, H2S-resistant coatings, and H2S-resistant hardware). For carbon dioxide, CO2 (Carbon Dioxide) specifies carbon dioxide requirements for geothermal equipment, and the transit case must protect geothermal equipment from CO2 corrosion during transport (including CO2-resistant materials, CO2-resistant coatings, and CO2-resistant hardware). For corrosion protection, NACE (National Association of Corrosion Engineers) specifies corrosion protection requirements for geothermal equipment, and the transit case must protect geothermal equipment from corrosion during transport (including corrosion-resistant materials, corrosion-resistant coatings, and corrosion-resistant hardware). For dangerous goods transport, UN 2935 (Carbon dioxide, refrigerated liquid) specifies dangerous goods transport requirements for geothermal equipment, and the transit case must protect geothermal equipment without compromising its UN 2935 features (including UN 2935 interlocks, UN 2935 labels, and UN 2935 documentation). For geothermal equipment ESD (Electrostatic Discharge), IEC 61000-4-2 (Electromagnetic compatibility (EMC)—Part 4-2: Testing and measurement techniques—Electrostatic discharge immunity test) specifies electrostatic discharge immunity test for electronic equipment, and the transit case must protect ESD-sensitive geothermal equipment without compromising its ESD features (including ESD-safe materials, ESD-safe packaging, and ESD-safe handling).

For geothermal equipment vibration, NACE (National Association of Corrosion Engineers) specifies vibration requirements for geothermal equipment, and the transit case must protect geothermal equipment from vibration during transport (including vibration isolation, vibration damping, and vibration monitoring). For geothermal equipment shock, NACE (National Association of Corrosion Engineers) specifies shock requirements for geothermal equipment, and the transit case must protect geothermal equipment from shock during transport (including shock isolation, shock damping, and shock monitoring). For geothermal equipment testing, NACE (National Association of Corrosion Engineers) specifies testing requirements for geothermal equipment, and the transit case must support the testing requirements of geothermal equipment (including test records, test documentation, and test traceability). For geothermal equipment logistics, NACE (National Association of Corrosion Engineers) specifies logistics requirements for geothermal equipment, and the transit case must support the logistics requirements of geothermal equipment (including equipment tracking, equipment documentation, and equipment handling). For geothermal equipment H2S corrosion protection, H2S (Hydrogen Sulfide) specifies H2S corrosion protection requirements for geothermal equipment, and the transit case must protect geothermal equipment from H2S corrosion during transport (including H2S-resistant materials, H2S-resistant coatings, and H2S-resistant hardware). For geothermal equipment CO2 corrosion protection, CO2 (Carbon Dioxide) specifies CO2 corrosion protection requirements for geothermal equipment, and the transit case must protect geothermal equipment from CO2 corrosion during transport (including CO2-resistant materials, CO2-resistant coatings, and CO2-resistant hardware).

Drilling Equipment, Well Logging Instruments, and Reservoir Characterization Equipment: Core Equipment Transport

Drilling equipment (MWD tools, LWD tools, drilling equipment controllers, drilling equipment sensors) are typically shipped as complete units with precision components, electronics, connectors, and documentation. The most critical areas are: connector protection (drilling equipment connectors such as pressure sensor connectors, data connectors, and signal connectors can be damaged by impact or by vibration, causing connection problems or equipment failure), component protection (drilling equipment components such as MWD tools, LWD tools, and drilling equipment controllers can be damaged by impact or by vibration, causing component failure or drilling equipment malfunction), and corrosion (drilling equipment is exposed to geothermal environments with H2S and CO2, which can cause corrosion if not properly protected during transport). Our drilling equipment cases use: connector protection (custom foam with zero-contact foam on connectors, and custom connector protectors to prevent damage), component protection (custom foam with zero-contact foam on components, and custom component protectors to prevent damage), corrosion-resistant materials (corrosion-resistant foam and corrosion-resistant coatings, for protection against corrosion in geothermal environments with H2S and CO2), 316 stainless steel hardware (for protection against corrosion in geothermal environments with H2S and CO2), vibration isolation (custom foam with vibration isolation properties, and custom vibration isolators to prevent component damage), and IP65 sealing (continuous silicone gaskets, for protection against dust and moisture during transport and storage at geothermal drilling sites and geothermal equipment facilities).

Case Design Specifications and OEM/ODM Capabilities

Our standard geothermal equipment case specification includes: 2mm thick 5052-H32 aluminum panels (or 3mm for heavy-duty applications over 50kg payload, or 4mm for drilling equipment modules that must meet structural requirements), Type II anodized (15-25μm) plus polyester TGIC powder coating (60-80μm) in matte black, gray, or custom color (black is preferred for geothermal applications, as it hides dirt and corrosion more effectively); continuous silicone gaskets (Shore A 50-60) providing IP65 sealing (IP67 available as option, for geothermal outdoor applications); 304 or 316 stainless steel hardware (latches, hinges, handles, rivets)—316 stainless steel is preferred for geothermal applications, as it is more corrosion-resistant in H2S and CO2 environments; CNC-cut closed-cell XLPE foam (40-80 kg/m³, customer-specified density based on payload weight and fragility) with ESD-safe option (surface resistance 10^6-10^9 Ω/sq) and corrosion-resistant option; heavy-duty draw latches (Southco or equivalent) with rubber bumpers; folding side handles (for cases over 15kg) or top handle (for cases under 15kg); stacking corners (recessed, for secure stacking); and a waterproof document holder (A4 size, inside lid).

Every geothermal equipment case we build is custom-sized to your equipment’s exact dimensions, with CNC-cut foam cavities that hold each component in its operational orientation. We don’t sell stock cases for geothermal equipment—because a 5mm gap means 5mm of potential movement during transport, and that’s where connector damage, corrosion damage, and component damage start.
