A closer look at Oil Tanker Operations

For effective SPM functioning, one requires various vessels, resources and protocols to ensure safe and efficient tanker mooring and unmooring at the SPM. Of course, for the entire ecosystem to function, tanker operations must also be accounted for. But what does that entail?

Tanker operations overview and objectives

This ranges from tanker berthing, hose connection and disconnection services to product transfer services and oil spill response services as required at the SPM. It is important that you cater for this with specialist personnel for maintenance and supervisory roles such as Project

Managers, Work Managers, Buoy Maintenance Superintendent, Mooring Master, Dive

Supervisors and Tanker Teams on a short and long-term basis.

To ensure that tanker operations at a Single Point Mooring Marine terminal are safe, on time and consistent in consideration with company requirements, your tanker operations plan should take Operation Manuals, HSE and necessary risk assessments into account.

Pilot Services

Pilot services should maintain that all operational personnel demonstrate a commitment to health, safety and environmental policies, and international best practices during tanker operations. 

If you are outsourcing tanker operations, it is important that your service provider acknowledges overall accountability for ensuring that they moor the tanker and unberth it from the buoy in the most efficient and safest manner possible.

Emergency Response Services

As part of your SPM operations and maintenance strategy, you should include studies and plans for pre-emption and fast reaction. In case of an emergency on the terminal, all transfer operations are ceased immediately, and equipment is secured as appropriate. It is necessary that swift and appropriate action be taken to minimise the effect of a contingency and this can only be done with a good plan and well-trained personnel.

Any incident on board a vessel operated should be responded to rapidly and in an efficient manner so that the personnel and asset safety is not compromised and we minimise any environmental impact.

In the case of oil spills, MARSOL firmly believes that prevention is better than cure. That is why we have thorough planning and preemptive studies to prevent them altogether. We help the client to identify high-risk areas during contingency planning which allow us to define priorities for protection in the event of an emergency and plan the appropriate response strategies.

That being said, should an oil spill occur, MARSOL oil spill response team can get the job done. 

It is important that the oil spill response team, as part of tanker operations, ensures that the affected areas achieve the acceptable level of cleanliness using cost-effective and environmentally friendly cleaning techniques. Utilising a team of qualified personnel, one should rapidly respond to recover lost hydrocarbons and deliver safe methodologies to minimise the amount of waste generated and impact of any release.

Tanker Operations: Training

It is important that one recognises the importance of developing and training the skill set of local resources. That is why MARSOL has embarked on a continuous improvement programme in improving the knowledge base of our Centre of Excellence, under the management of our Human Resource department.

We recognise that developing local resources is both prudent and cost-effective and adds significant value to the local community.


When dissecting tanker operations you will find that there is far more than meets the eye. At MARSOL, we commit to protecting the reputation of all stakeholders of the terminal, the environment and the personnel involved not only with rapid emergency response but with proven methods and protocols that favour sustainability.

Rethink your offshore terminal with an O&M Strategy

While your offshore terminal may seem like a small piece of the puzzle, it plays a crucial role that can make or break your business in the oil and gas sector. To ensure that your terminal, whether single-point-mooring or multi-buoy-mooring, operates efficiently with your long-term goals and budget in mind, you need a sound O&M strategy. 

Aspects of an offshore terminal O&M strategy

Your offshore terminal O&M strategy should serve to optimise and protect the integrity, reliability and availability of your offshore assets. This includes on-site management and operations, administration, engineering and maintenance execution. 

Inspection, Repair and Maintenance

Through applying integrity-based Inspection, Repair and Maintenance (IRM) and creating an asset history, your terminal O&M strategy should be able to modify classic philosophies and associated work programmes periodically to reflect changes brought about by any influencing factors and unusual events. This will reduce risk within the system, as change is inevitable.

Tanker operations

Your offshore terminal O&M strategy should make provision for all marine assets and resources to ensure that time and money is accounted for. This provision will also highlight procedures required for safe and efficient tanker mooring and unmooring at the SPM/MBM. This includes hose connection and disconnection services as well as product transfer services.

  • Pilot Services
  • Tanker Handling vessels
  • Emergency Response Services
  • Oil Spill Response

Marine Hose Management Services

To ensure safe and reliable operation of marine hoses, a good offshore terminal O&M strategy will cater for hose management as well. Make sure that your turnkey O&M service provider is meticulous about regulated testing and as well fit-for-purpose operation of marine hoses.

Associated services

  • Hose Inventory Management & Storage
  • Hose Change Out
  • Testing and CLASS
  • End-of-life assessment

Commercial Marine Products

Hardware provision is not an O&M service provider requirement, but it certainly is something to be included in your strategy. If your offshore terminal O&M partner can supply the desired marine products and can install, operate and maintain them according to manufacturer’s specifications – it’s definitely a bonus!

Products include

  •  HDPE Boats
  •  HDPE Modular Floating Docks
  •  HDPE Tanks

Why you need a turnkey O&M service provider

In the offshore oil and gas industry, many terminal service providers claim to be turnkey operations and maintenance providers, but they fail to meet the mark. This leaves you with unexpected operational costs and opens doors to risk, should multiple service providers fail to operate harmoniously. 

A true turnkey solutions provider should cover every aspect of your offshore operations and maintenance so that you can focus on your core business. This includes the supply and maintenance of mechanical and electrical hardware, staff management and training, on-site execution and third-party outsourcing. 

Such a provider gives you peace of mind through a single contact point and accountability.


The condition and operation of your offshore terminal can make or break your business in the oil and gas industry. To ensure that it functions at its very best, you need a sound O&M strategy and selecting a good long-term solutions partner is key. 

As pioneers in the holistic terminal operations and maintenance approach, MARSOL prides itself on being a turnkey offshore O&M service provider, serving both greenfield and brownfield projects.
