Hastelloy Heat Exchangers Removal for Marine and Offshore Facilities

Hastelloy Heat Exchangers removal context in Marine and Offshore

Hastelloy heat exchangers are specialized thermal management units constructed from nickel-molybdenum-chromium alloys, such as Hastelloy C-276, C-22, B-2, and Hastelloy-N. Installed removal from a marine or offshore operation also depends on the actual process, residual service, isolation status, surrounding systems, and facility access described in the marine and offshore evidence record.

The removal plan must be based on the submitted unit and site. This page does not imply a local crew, permit authority, preapproved lift, guaranteed pickup, or unconditional service availability.

Isolation and residual-service record

Before commercial or logistics commitments, document how both exchanger sides were isolated, drained, cleaned, released, and separated from the marine and offshore system. Unknown conditions should be identified as unknown.

• Check for material certifications (e.g., Titanium, Duplex stainless steel).
• Verify marine class approvals (ABS, DNV).
• Inspect for signs of pitting or crevice corrosion.
• Assess weight and dimensions for heavy lift and transport planning, especially for thick-walled high-pressure units.
• Plan for isolation and safe draining of hazardous or corrosive residual fluids (e.g., molten salts, concentrated acids).
• Ensure proper handling to prevent damage to specialized alloy surfaces or tube bundles.

Dismantling, loading, and freight planning

The physical plan should connect the hastelloy heat exchangers configuration to verified dimensions, weight, lifting points, access, staging, carrier profile, and responsibility boundaries.

• Assess weight and dimensions for heavy lift and transport planning, especially for thick-walled high-pressure units.
• Plan for isolation and safe draining of hazardous or corrosive residual fluids (e.g., molten salts, concentrated acids).
• Ensure proper handling to prevent damage to specialized alloy surfaces or tube bundles.
• Coordinate with specialized rigging and freight services for heavy industrial equipment.
• Ensure isolation from seawater intake and process fluid loops.
• Drain and flush residual brine or cooling media.
• Account for tight space constraints and weight limits on offshore platforms.

Written scope before work

Dismantling, rigging, loading, freight, scheduling, and payment are conditional project functions. A written scope must identify responsible parties, safety release, access rules, exclusions, equipment boundaries, carrier requirements, and commercial terms before performance.
