Explosion-Proof Level Switch Solutions for FPSO Vessels

Summary:
The oil and gas industry faces extreme operational challenges, particularly on FPSO (Floating Production Storage and Offloading) vessels, where safety and reliability are paramount. This article highlights how explosion-proof solutions—such as Trimod’Besta level switches—play a vital role in ensuring safe offshore operations, focusing on the case of the BW Pioneer FPSO in the Gulf of Mexico.


1. FPSO Operations and Safety Requirements

FPSO vessels like the BW Pioneer are crucial for offshore oil and gas production. Operating at water depths of 2,600 meters, these vessels must withstand extreme environmental conditions, including high currents, heavy waves, and strong winds.

A critical element of FPSO safety is reliable explosion-proof technology that can operate in hazardous zones (Zone 1) where flammable gases, vapors, and explosive atmospheres are present.


2. The Role of Trimod’Besta Level Switches

On the BW Pioneer FPSO, Trimod’Besta stainless steel level switches are installed in the connection room, which is subject to flooding during buoy connection operations. These switches:

  • Control the seawater pumping process, starting and stopping pumps automatically.

  • Prevent pumps from running dry, ensuring system reliability.

  • Are designed with flameproof housing and IP68-rated enclosures, allowing submersion up to 20 meters.

  • Feature gold-plated microswitch contacts for long-lasting performance in harsh marine environments.


3. Why Explosion-Proof Level Switches are Essential on FPSOs

Explosion-proof devices are critical on FPSO vessels due to:

  • Hazardous environment safety: Certified under EN 61079, these switches are built to prevent ignition in explosive atmospheres.

  • Durability: Withstand seawater exposure, tropical marine humidity (33–100%), and temperatures from +17°C to +45°C.

  • Reliable performance: Designed to work in challenging offshore environments with minimal maintenance.


4. The BW Pioneer Case Study

The BW Pioneer FPSO, operated by BW Offshore, is the first FPSO in the US Gulf of Mexico. It uses a Submerged Turret Loading (STL) system, allowing it to connect securely to a buoy even in wave heights of up to 6 meters, ensuring weather-independent operations.

By integrating Trimod’Besta explosion-proof level switches, the BW Pioneer guarantees seamless and safe operations, highlighting why high-quality ex-proof components are a must-have for offshore facilities.
