There are many challenges associated with maintaining the effective integrity of assets to improve operational performance and maintain offshore production levels in Brazil.

Companies specializing in offshore asset maintenance are predicting an increase in demand from 2021/22 when the effects of the Covid-19 pandemic are expected to be mitigated and activities reheated.

There is a new entry of players in the market for predictive, preventive, and corrective maintenance. Until 2015, this type of service was dominated by a relatively small group of companies. The understanding is that the emergence of other companies reflects a complete change in this situation that, in recent years, has suffered from the fall in much of the country’s industrial activities.

Good examples of asset integrity and maintenance are focused on current industry best practices, which have been developed over the years. Such practices note how innovation and technology can help shape the future of offshore maintenance.

In 2019 and 2020, with the oil crisis and the pandemic, Petrobras decided to hibernate platforms of lower productivity. Some units will be sold and others decommissioned. Platforms that will be hibernated will need to have appropriate procedures, for example, with corrosion protection. Both the new offshore units to be built, and those that will be sold, will have to be fully maintained until the destination is completed.

Based on these principles, SOBENA promotes the 4th Event on Integrity and Maintenance of Offshore Assets to be held on September 29, 2021.

It is a common fact that maintenance should be a priority from now on. In this webinar, we will bring together key stakeholders, including operators, regulators, supply chains, and industry experts, to discuss some of the key challenges facing the industry today and how we can use our knowledge, technologies, and expertise to find new, cost-effective and secure solutions for the future.

What is SPS?

SPS^TM is a patented structural composite comprising two metal plates bonded with a solid polyurethane elastomer core. The elastomer core provides support to the plates. It enhances buckling capacity and fatigue life of the structure.

Benefits of using SPS repair technology

• – Local and global strength reinstatement and strengthening
• – Superior to conventional crop and replace
• – Extremely fast process with no structural removal (up to 4x faster than conventional methods)
• – Non-disruptive
• – Better than the new structural performance
• – Minimises labour content and downtime

Cold Work SPS for FPSO Capixaba

Using the SPS® Cold Work solution to reinstate the deck of the FPSO Capixaba ensured:

• – 100% operational capacity was maintained throughout – tank below remained operational
• – A non-disruptive repair was completed much faster than crop and renew repair
• – Reinstated deck plate stronger than the original
• – Fire risk eliminated
• – No crude oil tank cleaning required
• – No under deck scaffolding required in confined space

Our well-trained SPS team proposed SPS Cold Work installation to deliver this permanent repair. We reinstated the existing deck and created a new composite section. A combination of bolts and structural adhesive was used to fit and join the steel components to form airtight cavities. The elastomer core was injected between the cavities. All steel components were prefabricated before being shipped on board for installation. This reduced the cost of the project. Welding requirements were eliminated. Time was reduced for the installation team, which in turn simplified project logistics. The design and process were evaluated and approved by ABS Brazil. 

The SPS cold work solution reduced the amount of in-situ offshore work and POB requirements, allowing the FPSO to remain in operation. The fire-related risk was eliminated during the repair. SPS cold work was a great solution, as well as being class approved, for steel repairs where both hot work and POB are a constraint.

History Of Welding

History evidence has shown that ancient Egyptians learned to weld iron together. Small golden boxes were discovered with pressure-welded lap joints from over 2,000 years ago.

During the Industrial Revolution in the 1800s, Sir Humphry Davy produced the first electric arc between two carbon electrodes using a battery. In 1836, his cousin, Edmund Davy discovered acetylene. In 1881, forge welding technology was developed when Auguste de Méritens used arc heat to join two pieces of lead plates together.

Modern welding did not start until the widespread availability of electricity at the start of the 20th century. In 1919, C.J. Holslag invented alternating current welding. It replaces electric arc welding as the most prevalent form of welding in the United States. Welding continued to increase and was in high demand due to the First and Second World Wars.

What is Welding In Maritime Industry?

Welding involves joining metals or thermoplastics together with the use of heat. In most instances, the welding job required to build ships and repair metal parts and structures. Maritime welding job aims to produce joints that are watertight and oil-tight.

Welded joints, as opposed to riveted joints, reduce steel weight, and require less maintenance than riveted joints. Welding technology is crucial in the shipbuilding industry for producing smooth hull surfaces, reducing hull resistance and power needs.

What is the best-known welding method used?

Gas tungsten arc welding (GTAW) – An electric arc welding process that produces an arc between a non-consumable electrode and the work to be welded.

Gas metal arc welding (GMAW) – An electric arc is formed between the metal and a wire electrode, applying heat to the metal pieces. This action melts and fuses the parts together to form a permanent bond.

Why Is Welding Important to the Shipbuilding Industry?

Welding is critical for Offshore operations such as the construction of new projects and for the maintenance of existing facilities.

Welding is important in the shipbuilding process because it can create joints that are water and oil tight. As you can imagine, a strong weld is essential to the integrity of the ship. On one large ship, it can have hundreds of joints that require welding.

Shipbuilders face many challenges in the shipyard that could prevent progress and create downtime during operation. The need for durable equipment and an experienced welder that can address the demands of different applications is vital.

What is carbon footprint?

A carbon footprint is the total amount of greenhouse gases that are generated by our actions. It corresponds to the amount of greenhouse gases (GHG) that we produced directly and indirectly with our lifestyle and activities.

Carbon footprints are usually measured in tons of CO2, during the period of a year. The average carbon footprint for a person globally is around 4 tons.  The average global carbon footprint per year needs to drop under 2 tons by 2050. In this way, we can avoid a 2-degree rise in global temperatures.

How much carbon footprint have we created over the years?

According to the world In data, more than 400 billion metric tonnes of carbon have been released into the atmosphere. Since 1800, the consumption of fossil fuels has increased carbon emissions. 

Prior to the Industrial Revolution, emissions were very low. Growth in emissions was still relatively slow until the mid-20th century. In 1950, the world emitted 6 billion tonnes of Carbon. By 1990, this had almost quadrupled to 22 billion tonnes. Emissions have continued to grow rapidly. Currently, we are emitting over 36 billion tonnes each year.

Did our current pandemic slow down carbon emissions?

When the World Health Organization officially declared a pandemic on 11 March 2020.  The planet has already warmed by around 1.2C since pre-industrial times. There was an unprecedented reduction in carbon emissions as a result of shutdowns of the economy. Animals returned to big cities and air pollution declined in cities because of the reduction in traffic.

The reported drops in carbon emissions and other greenhouse gases, while helpful, are insufficient to slow climate change.

Alex Hall, professor of atmospheric and oceanic sciences at UCLA

However, a reduction in carbon emissions isn’t enough to significantly curb climate change. The emissions have taken place over the past several decades. To affect ongoing and future climate change, the recent emissions drop would have to be sustained over a much longer period than the likely duration of the coronavirus outbreak.

Emissions would need to drop by more than 25% to see a total drop in the amount of carbon in the atmosphere, and thus slow an annual global rise in temperatures.

Tips on reducing carbon emission by yourself

• 1) Reduce energy usage in your home
• 2) Regularly service your car to keep it more efficient
• 3) Replace to LED lights
• 4) Consider the fabric of your clothes purchase.
