⚓ Bunker Decisions at Sea: When COQ Is Available but FOBAS Results Are Still Pending

Life in shipping is full of decisions that cannot wait for perfect information.

Sometimes the vessel is ready to sail, operations are complete, cargo plans are confirmed — yet one small technical question remains. A question that quietly carries operational, financial, and safety implications.

One such moment arises during bunkering operations, when the Certificate of Quality (COQ) is available, but the FOBAS laboratory analysis is still pending.

Recently, a situation like this unfolded during a Singapore bunker call, where VLSFO and LSMGO were supplied to the vessel. The COQ was received before supply, and FOBAS samples were landed for testing, but the detailed analysis report would only arrive several days later.

The practical question then becomes:

Can the vessel start using the supplied VLSFO based on the COQ, or should she continue operating on LSMGO until the lab analysis confirms the fuel quality?

This is where operational judgment, experience, and risk awareness come into play.

🚢 COQ vs FOBAS: The Operational Dilemma

Every experienced Chief Engineer and Master understands that fuel quality is not just paperwork — it directly affects the vessel’s machinery health and voyage safety.

The Certificate of Quality (COQ) provided by the supplier indicates that the fuel meets required specifications. However, many ship operators today rely on independent laboratory testing such as FOBAS to confirm that the supplied fuel is fully compliant with ISO standards.

In many bunker ports, including Singapore, vessels often sail before the full laboratory analysis is completed.

This creates a familiar operational dilemma:

• If the vessel immediately uses the supplied VLSFO, operations remain efficient and cost-effective.
• If the vessel continues using LSMGO until confirmation, it reduces risk but increases operational costs.

Neither option is wrong — the key lies in risk management and communication between ship and shore.

The Master, Chief Engineer, operators, and technical managers must evaluate the situation calmly and decide the safest and most practical course of action.

🧭 The Leadership Lesson: Responsible Decision-Making

Shipping teaches a powerful lesson: not every operational decision comes with complete certainty.

Sometimes the Master must make a judgment call.

In this case, the vessel arrived Singapore already operating on LSMGO, with an unpumpable VLSFO ROB of about 50.95 MT remaining onboard. Fresh VLSFO was supplied, samples were taken, and FOBAS testing was initiated.

But the voyage cannot wait for laboratory timelines.

This is where responsible leadership and transparent communication become essential.

The Master informs the operator.
The Chief Engineer reviews fuel parameters.
The shore team evaluates the COQ and supplier reputation.

Together, they decide the safest path forward.

Because in shipping, leadership is not about avoiding responsibility — it is about making thoughtful decisions that protect the vessel, the crew, and the voyage.

🤝 Final Thought for the Shipping Community

Shipping is a profession where every decision carries responsibility.

From bunkering plans to fuel usage strategies, these choices often happen quietly — without headlines, without recognition.

But they matter.

Because one good operational decision can protect:

⚓ The vessel’s engines
⚓ The voyage schedule
⚓ The safety of the crew
⚓ The reputation of the company

And those decisions are made every day by Masters, Chief Engineers, and operators across the world’s oceans.

That quiet professionalism is what truly keeps the global shipping industry moving.
