Maintaining your offshore assets’ engines and mechanical systems ensures your vessel functions efficiently.
The Vessel Classification Society establishes and maintains technical standards for the construction and operation of ships and offshore structures. They conduct regular surveys and inspections to ensure the smooth operation of the Vessel. Engineers are on board to ensure that there are annual inspections of the vessel, with a full survey undertaken every 4 to 5 years. The port authority checked on the mechanical condition of the ship.
Be it cruise vessels or offshore assets, the maintenance schedule needs to be planned well by the owners to allow the maintenance society to undertake the repair work as and when needed.
How Is Maintenance Work Done Onboarding a Vessel?
In the earlier days, the number of crew members and engineers on a ship was large. Thus, the maintenance was carried out fast and easily. However, in the present scenario, the number of crew members and engineers on the ship has reduced drastically.
Many ships carry only 3-4 engineers onboard a ship. The time required to carry out maintenance on the ship has reduced as well. The number of crew members is lesser, and the amount of machinery is more. Thus, maintenance requires more manpower and time.
Types of Ship Maintenance
Efficient planning and proper use of the equipment is the key to maintaining a ship. There are different types of procedures undertaken by the engineers on board and on the port.
1. Scheduled maintenance:
This is a precautionary measure to avoid probable damages and to adopt necessary precaution measures. It is also known as the Planned Maintenance System. A team from the maintenance company will schedule servicing of the vessel as per the running hours like 4000 hours or more. The provider will send representatives after proper intervals to continue the servicing in a consistent manner. In such a maintenance program, the parts must be changed that are mentioned in the schedule even if they are fully functional.
2. Corrective maintenance:
Sudden breakdowns can be dangerous and unfortunate. Corrective maintenance is dedicated to preventing emergencies. This program can become costly especially if the breakdown severely impacts other parts of the ship. It is thus necessary to ensure that regular inspection is conducted.
3. Conditional Maintenance:
Machinery parts should be inspected on a regular basis to detect the underlying defects and errors. Issues need to be corrected as soon as possible to restore the ship’s functional capability.
The condition of a machine can be accurately checked by using powerful sensors. Inspection reports need to be sincerely followed by experienced specialists. If wrong interpretation might occur, it will lead to acute machinery damage.
Final Takeaway
1) Maintaining your offshore assets’ engines and mechanical systems ensures your vessel functions efficiently.
2) More manpower is needed for offshore maintenance jobs as crews working onboard have been reduced.
3) Schedule maintenance is a precautionary measure to adopt necessary precaution measures.
4) Corrective maintenance is dedicated to preventing emergencies.
5) Conditional inspection reports need to be sincerely followed by experienced specialists.
5 Future Predictions Of The Offshore Industry And Why Is It Better For The Environment?
1) The Lines Between Fossil And Renewable Energy Will Be Blurred Today, nearly every product a consumer buys has a fossil fuel somewhere in how it is made or delivered. Coal requires little technology and offers a great deal of energy. As such, it is a stubborn and persistent part of the high-CO2 energy system.…
1) The Lines Between Fossil And Renewable Energy Will Be Blurred
Today, nearly every product a consumer buys has a fossil fuel somewhere in how it is made or delivered. Coal requires little technology and offers a great deal of energy. As such, it is a stubborn and persistent part of the high-CO2 energy system. Dealing with it will take determined action by governments to provide competitive alternatives.
In recent years, better renewable electricity has been generated efficiently. Rapid progress with renewable electricity technologies has made the price affordable. This leads Energy Experts to look at renewable energy as being the future of our energy resources.
In this way, we can free fossil fuels and coal to produce more sophisticated carbon products. Hydrocarbons and polymers can make it a feedstock rather than a fuel.
2) “Smart Oilfield” Technology
Digital oilfield technologies replicate an oilfield’s performance on a computer. Engineers can gather and monitor production through a tablet or mobile device.
At the end of the day, this data provides key indicators of oilfield well-being and performance. In this way, it improves and simplifies accurate decision-making.
With gas demand set to persist until at least 2050, there will be increased costs and activity on older pipeline systems all around the world. In North America, pipeline systems continue to be repurposed and undergo change of service due to shifts in where gas is produced and consumed, and LNG exports being allowed.
From a technology standpoint, the ideal solution would need to seamlessly connect all systems and hardware platforms across the various fields of operation, integrating exploration, drilling and production facilities, and ultimately delivering useful data and video streams to a central location, allowing the operators to make better and quicker decisions.
3) The challenge of rig decommissioning
The offshore oil and gas sector took off 50 years ago. The largest oil rigs may extend hundreds of feet to the bottom of the seabed and be supporting multiple platforms full of technical equipment and accommodation for workers. Thousands of huge bulky structures such as offshore rigs, platforms, and pipelines are nearing the end of their current useful life.
One of the biggest challenges facing oil and gas companies is the cost of decommissioning aging rigs around the world. The cost will reach $13bn a year by 2040.
More than 600 rigs will be decommissioned by 2021. Sinking the rigs is not feasible. Oil companies need to come up with environmentally friendly ways of decommissioning rigs or face a potentially huge backlash from increasingly environmentally conscious consumers.
As of January 2018, the North Sea was home to 184 offshore rigs, while the Golf of Mexico had 175 and the Persian Gulf housed 159.
4) Digital transformation offshore
Since the Industrial Revolution, the Oil & Gas industry has played a pivotal role in the economic transformation of the world. It fuels the need for heat, light, and mobility of the world’s population. Today the oil and gas industry is able to redefine its boundaries through digitalization.
Asset owners increasingly see the benefit of gathering data to improve operations. They are looking for ways to own both the data they generate and the technology that enables them to manage maintenance programs. Digital technology such as real-time monitoring, accurate reporting for compliance purposes, integration of Wi-Fi, and location-based technologies are examples of this trend.
More oil and gas companies are taking steps to capture and learn from smart data to make their operations smarter and reduce costs. Largest fleet owners are expected to be the most aggressive in leading this development.
5) Enabling greater use of stranded offshore gas
The stranded gas reserve is a natural gas field that has been discovered but the gas fields are too deep to drill into.
Offshore gas producers face significant challenges in some of the world’s largest natural gas resources. They are found at great distances from the biggest gas markets and without access to export infrastructure routes.
Substantial growth in FLNG technology can offer a solution to unlock the development of stranded offshore gas assets. Production can be exported by LNG carriers rather than uneconomic pipelines.
In some locations, companies may prefer to send LNG direct to the final market’s entry point rather than processing gas onshore.
What Is SPS Overlay? SPS (Sandwich Plate System) is a structural composite material comprising two metal plates bonded with a solid polyurethane elastomer core. The SPS layout retains the existing steel plate and reinforces it with a new steel layer and a polyurethane core. This will result in a stronger and flatter surface. SPS repairs…
SPS (Sandwich Plate System) is a structural composite material comprising two metal plates bonded with a solid polyurethane elastomer core.
The SPS layout retains the existing steel plate and reinforces it with a new steel layer and a polyurethane core. This will result in a stronger and flatter surface. SPS repairs and strengthening can be undertaken while the vessel is still in service. Choosing SPS can eliminate the need to wait for an offshore shutdown period.
ASOM SPS Case Study: SPS Reinstatement of FPSO’s Pontoon Deck
Our operations manager Mr. Rajesh Pillai had led our structure team and injection team to complete the project successfully during the COVID-19 pandemic. We have a tight-knitted team who will ensure we complete the project in a short and efficient time frame.
Working in a limited headspace of less than 300mm, our team have taken extra precautions and time to ensure the injection process is carried out safely and efficiently for our client.
The SPS deck reinstatement was substantially quicker than an equivalent conventional steel repair.
SPS Layout: Able to adapt to all working conditions.
Due to the confined work location, our Elastomer injection machine was to be placed 18m away.
We worked out a detailed plan to reduce all the space restrictions with our SPS Technician, Khun. After much planning, SPS elastomer core was injected to fully reinstate the strength and integrity of the structure.

SPS Overlay Installation Process – Suit Different Demanding Applications
As a steel-elastomer-steel composite, it typically reinstates a structure beyond its original strength. The SPS Overlay installation process will evolve accordingly to suit different demanding applications. A reduced heat SPS installation method is used where fuel oil tanks must be protected from heat input during the repair. This method involves the use of non-direct welding, adhesives, and stud welded perimeter bars.
What is our proposed SPS solution for MODEC?
We applied a reduced heat input method to reinstate steel in various areas on decks B, C, D, the top of the wheelhouse, and the upper deck. Structural adhesives are used to fix perimeter bars to the deck. New top plates (6-8mm thick) are welded to the bars to form air-tight cavities. Lastly, a 25-mm elastomer core was injected.
