Offshore Pumping Solutions

Engineered pumping equipment for offshore platforms, FPSOs, and oil & gas installations

Offshore pumping equipment serves the demanding duty cycles, severe service conditions, and stringent safety regulations of platforms, drilling rigs, FPSOs, and floating production units. Pumps must combine reliability, redundancy, materials suitable for sour service and seawater, and certification for hazardous areas (ATEX, IECEx). We supply pumps from European manufacturers with the engineering documentation, NACE-compliant materials, and class society approvals required for offshore installations.

Technical Overview

A typical offshore platform operates dozens of pumps across multiple services: produced water, oil export, water injection, fire fighting, cooling, fuel oil, slop, sewage, drains, and chemical injection. Each service has its own materials, redundancy, and certification requirements. Equipment must withstand vibration, motion, salt-laden atmospheres, and limited maintenance windows. Selection is governed by API 610 (centrifugal pumps), API 674/675/676 (positive displacement), and the platform's certifying authority.

Recommended Equipment

Pump Types for Offshore pumping

API 610 Process Pumps

Heavy-duty centrifugal pumps for hydrocarbon process service, water injection, and oil export. Available in OH, BB, and VS configurations.

Typical Brands: KSB, Sulzer

Fire-Fighting Pumps

Vertical turbine seawater pumps and diesel-driven fire pumps certified to NFPA 20 and SOLAS for offshore fire main service.

Typical Brands: KSB, Sulzer, DESMI

Cooling Water Pumps

Large vertical pumps drawing seawater for cooling, often with cathodic protection and special coatings against biofouling.

Typical Brands: KSB, Sulzer, DESMI

Chemical Injection Pumps

Metering pumps for corrosion inhibitor, scale inhibitor, biocide, and methanol injection at flowline and wellhead points.

Typical Brands: SPX Flow, Verder

Slop, Drain, and Sewage Pumps

Self-priming and submersible pumps for the platform's drain and sewage systems, in ATEX-certified configurations where required.

Typical Brands: SPX Flow, DESMI, Azcue

Engineering Considerations

  • API 610 / API 682 compliance for process pumps and seals
  • NACE MR0175 / ISO 15156 materials for sour (H₂S) service
  • ATEX / IECEx zone certification for hazardous area installation
  • Class society approval (DNV, Lloyd's, ABS, BV)
  • Redundancy: 2x100% or 3x50% for critical services
  • Materials: duplex, super-duplex, 6Mo, Inconel for seawater and produced fluids
  • Vibration, shock, and motion design criteria
  • Maintenance access through limited deck hatches and small openings
  • Spare parts strategy for remote operation

Typical Applications

  • Crude oil export from FPSO storage
  • Water injection for reservoir pressure maintenance
  • Seawater lift for cooling and fire main
  • Produced water re-injection
  • Methanol and chemical injection
  • Heating medium circulation
  • Slop and drain collection
  • Sewage and grey water handling
  • Fire fighting (jockey, main, standby diesel)
  • Helideck deluge system

FAQ

Common technical questions about offshore pumping solutions.

Process pumps are governed by API 610 (centrifugal) and API 674/675/676 (positive displacement). Mechanical seals follow API 682. Materials in sour service (H₂S) must comply with NACE MR0175 / ISO 15156. Hazardous area certification is per ATEX (EU) or IECEx (international). The platform's class society (DNV, Lloyd's Register, ABS, BV) sets construction and inspection requirements.
Common materials include super-duplex stainless steel, 6Mo austenitic stainless, and nickel-aluminium bronze for seawater service. Internal trim selection accounts for chloride concentration, dissolved oxygen, and temperature. For deep-water lift duties, titanium is sometimes specified for corrosion resistance in stagnant seawater.
Offshore platforms operate continuously in remote locations where maintenance is logistically difficult. Critical services such as fire main, cooling water, and process pumps are typically installed as 2x100% or 3x50% trains so that any single pump failure does not interrupt production or compromise safety. This is reinforced by class society and HSE requirements.
ATEX is the EU directive (2014/34/EU) governing equipment for use in potentially explosive atmospheres. Offshore platforms have defined hazardous zones (Zone 0, 1, 2 for gas; 20, 21, 22 for dust) and pumps installed in those zones must be certified for the corresponding category. International equivalents are IECEx and country-specific schemes (UL, CSA).
Standard factory acceptance testing includes hydrostatic shell test, performance test (head, flow, power, efficiency), NPSH test, mechanical run test, and vibration measurement. For critical services, additional tests cover string testing with the motor, witness testing by the operator or class surveyor, and full documentation packages including material certificates and NDE reports.
