Floating production storage and offloading (FPSO) units are on the upward trend in the oil and gas industry because of their flexibility to meet changing demands in an unpredictable market. Yet, without good preservation strategies during construction and delivery, FPSO fabricators and owners can be in for a negative surprise when they encounter corrosion problems during FPSO commissioning or thereafter. VP Technologies offer practical and effective solutions to avoid these unwanted corrosion-related downtime episodes to promote smoother commissioning and better durability.
A Corrosive Environment
FPSO topside equipment is often built near ocean ports and spends the rest of its service life in a marine environment. High temperatures, humidity, and salt spray create a perfect atmosphere for corrosion propagation. To make matters worse, certain types of equipment must be flushed or hydrotested during construction and commissioning, introducing corrosives that threaten to compromise the internal integrity of the equipment. While corrosion consequences can be drastic, a few simple preservation strategies in key areas will go a long way toward preserving equipment until the time of commissioning.
Preserving Electricals and Electronics
Electricals and electronics are the brains and nerve centres of a FPSO. Fortunately, electronics and electricals can be protected using VpCI® emitters which are available in multiple sizes—from the VpCI®-101 Device that protects 1 ft³ (28 L) of space to the VpCI®– 308 pouch that protects 35.3 ft³ (1 m³)—and release Vapor phase Corrosion Inhibitors that fill the enclosure, adsorbing on metal surfaces as a protective molecular layer.
Protection During Hydrotesting
Products such as those in the VpCI®-649 Series can be added to the hydrotest water for protection during hydrostatic testing and can be dosed at higher concentrations for extended periods of preservation. These hydrotest additives are both film-forming and vapor-phase corrosion inhibiting for protection of hard-to-reach areas inside valves or systems that are capped subsequent to hydrotesting.
Preserving Tanks, Vessels, and Flow Paths
Another means of internal protection is to apply VpCI®-337 or CorroLogic® Fogging Fluid VpCI®-339 . Inhibitors into flow paths of gas turbines and other rotating equipment. They also work inside tanks, vessels, and other enclosed voids that could otherwise be difficult to protect.
External Protection
Turbines and other equipment fogged with VpCI® Technology are often wrapped in VpCI® Films such as VpCI®-126 HP UV Shrink Film and MilCorr® VpCI® Shrink Film—both to protect equipment externals and to trap Vapor phase Corrosion Inhibitors inside the equipment.
The CORINJ sidestream 
system is designed to 
measure corrosion and 
chemical efficiency in a 
continuous way, even 
when inline monitoring 
points are not available. 
The CORINJ sidestream is 
custom built based on 
customer requirements 
and Specifications. The 
system can be integrated 
into any system and devices can be serviced quickly and easily without having to conduct live breaking containment retrieval work.
Monitoring Options
The sidestream has various options, you can choose from 2 to 10 monitoring points that include different types of probes and 
corrosion coupons.
Assembly
The unit’s main block has different ports for various types of monitoring. The ports have NPT union fittings, which let you screw in and seal the devices.
H2S Monitoring
The CORINJ sidestream offers continuous ‘real-time’ H2S monitoring through a side-stream unit. If you want to monitor suspect, or known H2S issues this side-stream is ideal as it can be tied into the exact point on a specific system or wells.
ER Probes
ER probes are used to provide live corrosion rate readings or to gather and store data of corrosion rates and metal loss. The probes can collate data via logging equipment or can be connected to a transmitter which feeds back to the client DCS to provide live 
data feedback.
Corrosion Coupons
The corrosion coupons are aligned with the inner wall of the sidestream. They measure corrosion rates and pit depths by metal loss over a known time period.
Bio Probes
Sessile bacteria attached to the bio studs can be collected and analysed to check the efficiency of the chemical injection systems or biocide regimes using Bio Probes in oil and gas production.
Continuous Flow
This is key to a sidestream working effectively. The outlet of the side-stream is usually routed back downstream in the system where the pressure is lower, so the flow is continuous.

The coating industry is continually evolving, with advancements in technology and materials pushing the boundaries of what is possible. To ensure that professionals are equipped with the latest knowledge and best practices, continuous training and upskilling are essential. Recognising this, the Corrodere Academy is rolling out its latest offering: the Powder Coatings Course. This is part of the renowned Train the Painter programme, designed to raise industry standards across the globe.
The Advantages of Powder Coatings
The powder coatings sector has seen tremendous growth and innovation in recent years. Powder coatings are used globally in numerous industries and the advantages include:
Environmental Friendliness: Unlike traditional liquid coatings, powder coatings emit zero or near-zero volatile organic compounds (VOCs). This makes them environmentally friendly, contributing to reduced pollution and safer work environments.
Cost-Efficiency: Over-spray from powder coatings can be retrieved, screened/cleaned and reused, resulting in nearly 100 % usage of the product. This cuts down on waste, making
the process more cost-effective.
Durability: Powder coatings are known for their excellent resistance to corrosion, chipping, abrasions, and weathering. Their hard finish is tougher than conventional paints, ensuring long-lasting protection and aesthetic appeal.
Thicker Coatings: Unlike liquid coatings, it’s easy to apply thicker coats using powder without the risk of runs or sags. A consistent, even coating can be achieved.
Uniform Finish: The electrostatic application process ensures that surfaces have a smooth and consistent finish without the appearance of brush strokes.
Wide Range of Finishes: From high-gloss to matte, and textures from smooth to rough, powder coatings offer a broad spectrum of finishing options, catering to various aesthetic and functional requirements.
Quick Turnaround: Due to the nature of the application and curing process, products coated with powder coatings are ready for use or shipment more quickly than their liquid-coated counterparts.
The application of powder coatings can be an automated or manual electrostatic process. Articles can also be dipped in fluidised beds. Incorporating these advantages into your operations can offer businesses a competitive edge, not just in terms of product quality and longevity but also in eco-responsibility and cost savings. The move towards more sustainable and efficient solutions like powder coatings is not merely a trend but a forward-thinking approach to modern manufacturing and finishing processes.

Brookes Bell, the multi-disciplinary technical and scientific consultancy for the marine and energy sectors, has received the Technology and Innovation Award from the Mersey Maritime Industry Awards (MMIA) for its Corrosion Assessment Service for the maritime sector.
The Liverpool-based company received the honour on 2 November during a ceremony at the prestigious Liverpool Cathedral. The award, which was sponsored by The Manufacturing Technology Centre, recognised Brookes Bell’s Corrosion Assessment Service, officially known as CMAP, as a crucial innovation that improves vessel owners’ awareness of onboard corrosion issues, enabling them to understand the required repairs ahead of time before the effects of corrosion become too severe or result in significant lay-up time.
CMAP, which is offered by The Lab at Brookes Bell, uses a highly refined Pulsed Eddy Current Array (PECA) inspection technique, combined with Brookes Bell’s 3D data visualisation software, to create an overview of the condition of a vessel’s steel, remaining wall thickness and material loss.
According to the Association for Materials Protection and Performance (AMPP), the collective global cost of corrosion to shipowners is estimated to be as high as $80 billion.
Earlier this year, Brookes Bell received official accreditation for its CMAP service on naval and commercial vessels from Lloyd’s Register classification society. The technology was tested and honed on the Royal Navy’s Type 23 frigates, landing platform docks, several Ro-Pax ferries and superyachts in the commercial sector to enable Brookes Bell to develop a more comprehensive understanding of corrosion assessment.
