OFFSHORE ENGINEERING & MARINE

Valve applications for offshore and shipboard systems.

See how Vornet valve categories support offshore process modules, seawater systems, vessel utilities and marine loading.

APPLICATION OVERVIEW

Four critical parts of the offshore & marine process.

01OFFSHORE PROCESS & PRODUCTION

OFFSHORE PROCESS & PRODUCTION

Isolate compact offshore process systems.

Platform and FPSO topsides separate, treat and export oil and gas within weight- and space-constrained modules.

WHERE IT IS USED

  • Production separators
  • Gas compression
  • Water injection
  • Export manifolds
APPLICATION CHALLENGE

Corrosive atmosphere, sour media and limited maintenance access raise reliability and containment requirements.

VORNET APPROACH

Compact ball, gate and check valves use project-specified materials, coatings and actuation for offshore service.

02SEAWATER & FIREWATER

SEAWATER & FIREWATER

Keep seawater utility systems ready.

Seawater lift, cooling, ballast and firewater systems support safety and continuous offshore operation.

WHERE IT IS USED

  • Seawater lift pumps
  • Cooling water
  • Firewater ring main
  • Ballast systems
APPLICATION CHALLENGE

Chlorides, marine growth and large flow rates can cause corrosion, fouling and high operating torque.

VORNET APPROACH

Corrosion-resistant isolation and check valves are selected around material compatibility and pump protection.

03SHIPBOARD UTILITIES

SHIPBOARD UTILITIES

Control essential vessel services.

Fuel, bilge, ballast, cooling, steam and compressed-air systems run throughout marine machinery spaces.

WHERE IT IS USED

  • Fuel oil
  • Bilge and ballast
  • Engine cooling
  • Steam and compressed air
APPLICATION CHALLENGE

Vibration, compact piping and mixed media require robust valves that remain serviceable onboard.

VORNET APPROACH

Ball, gate, globe and check valves are assigned to isolation, regulation and non-return duties.

04MARINE LOADING & EXPORT

MARINE LOADING & EXPORT

Protect product transfer at the vessel interface.

Loading arms, hoses and export lines transfer crude, LNG or refined products between shore, platform and vessel.

WHERE IT IS USED

  • Marine loading arms
  • Tandem offloading
  • Export risers
  • Emergency release systems
APPLICATION CHALLENGE

Vessel movement and emergency events demand rapid isolation and dependable containment.

VORNET APPROACH

Automated ball valves and check valves coordinate emergency shutdown, routing and reverse-flow prevention.
