The Tema laycan breakdown is worth attention not because vessels stopped moving, but because the document governing their movement kept publishing on time while the sequence it described stopped binding anyone.
The schedule remained intact on paper for months after it had ceased to allocate berths operationally.
The financial damage accumulated in that gap — between a published instrument and the berthing reality it no longer controlled.
1. The Operational Mechanism
The mechanism is straightforward.
The National Petroleum Authority (NPA) publishes a monthly berthing sequence for Tema's single dedicated petroleum berth, assigning each Bulk Import, Distribution and Export Company (BIDEC) a laycan window of roughly three to five days.
Eight to ten cargoes are sequenced per month against one berth that handles one vessel at a time, about three days per discharge.
International traders nominate vessels, fix chartering and structure cargo hedges against those published windows.
The chain downstream of the schedule assumes the schedule means what it says.
2. Sequence Degradation
The sequencing failed before the physical queue visibly broke.
Through Q1 the schedule was revised four times; in Q2, seven — most without consultation.
Revisions in themselves are routine.
What changed is that the NPA moved to a discretionary override, berthing off-schedule vessels ahead of operators who had arrived inside their assigned windows.
A BIDEC tanker would present Notice of Readiness (NOR) on arrival, exactly as the document instructed, then sit at anchorage for twenty to thirty days while vessels that appeared a week later berthed on an emergency classification.
The NOR was tendered on time and was worthless.
Laytime did not trigger, because the slot the NOR referenced no longer functioned as a slot.
3. The Commercial Illusion
Nothing in the visible chain announced this.
NPA kept publishing.
BIDECs kept nominating against published dates.
Traders kept matching loading windows to Tema arrivals.
The berth kept discharging.
Each individual action looked compliant.
The break sat in the relationship between the published sequence and the order vessels actually berthed — invisible until a cargo due on day X surfaces on day X+22 and a downstream terminal runs dry.
4. Contractual and Commercial Consequences
The contractual consequence followed with a lag.
Charterparty “awaiting berth” provisions assume a queue — a first-come ordering that demurrage logic attaches to.
At Tema there was no longer a queue in any enforceable sense; berthing order had become discretionary.
A vessel inside its window found its NOR rejected on the basis that the slot had lapsed, moving laytime exposure from owner to charterer with no contractual trigger to resist it.
BIDECs paying demurrage upstream to owners had no recovery against the NPA, which bears no contractual cost for revising its own schedule.
Reported demurrage and associated cost across the first half ran past USD 40 million, traced through at USD 0.47–0.60 per litre at the pump.
The cost had nowhere to settle.
It fragmented across parties who each held a contract assuming someone else was managing sequence.
Operator Reality Rule: Once a contract is signed, structure is fixed.
5. Operator-Side Observations
The operator reading shows up off the demurrage tally.
By trade accounts, planners had stopped using the published schedule for voyage planning and were calling the NPA every forty-eight hours to confirm which three vessels berthed next, with the answer changing four times in a single week.
When the parties whose function is to plan against a document stop reading it and start phoning for verbal confirmation, the instrument has been abandoned in practice while still produced on schedule.
6. Why Standard Clauses Fail to Protect
This is also why the standard clauses do not catch it.
Force majeure does not apply: the port is open and operating.
Demurrage recovery does not apply cleanly: the charterparty clause presumes a queue that no longer exists.
Both “the port is functioning” and “the port is not functioning in the order you contracted around” were true at Tema at the same time.
There was no event to clause against — which is why neither the war-risk adjustments seen in the Red Sea nor the recovery curve of a customs strike map onto it.
7. Systemic Architecture Risk
The same architecture — published berthing slots against constrained single-user infrastructure — exists in Pakistan's RLNG scheduling, Bangladesh's petroleum laycan system and Sri Lanka's CPC allocation.
At Tema, the schedule continued publishing after operators had stopped planning against it.
