Port congestion is rarely a single cause. It is a stack of small causes: a weather closure last week, a labour rotation, a shortage of container moves per hour, a chassis shortage at the back of the gate, one berth out for maintenance. Each of these alone is manageable. Stacked together across a fortnight, they turn a predictable 18-hour call into a three-day drift, and every supplier in the chain feels the shockwave.
Chennai Port has experienced its share of this over the last three years. Some of it was post-pandemic catch-up. Some of it was genuine infrastructure stretch. The honest answer for vessel agents: you cannot eliminate congestion, but you can organise your side of the call so that nothing inside your control adds to the delay.
Pre-clearance is the single biggest lever
The mistake we see most often is treating customs paperwork as something to initiate when the vessel is already in the inner anchorage. By then you are competing with every other agent's paperwork for the same set of officers. Marsea pre-files bonded store declarations, provision imports, and spare-parts clearances on a standing basis the moment the ETA drops into a confirmed window. In practice, that means paperwork is usually ready before the vessel is alongside.
For shipping lines, the practical ask is simple: share the noon report and the latest ETA update as soon as it is known. A four-hour head start on documentation is usually the difference between alongside-on-arrival and next-watch delivery.
Batching your supplies in one delivery window
Every alongside delivery uses gate-pass capacity. If you raise separate requisitions for provisions, bonded stores, deck stores, and spare parts with different lead times, you end up consuming multiple delivery windows - and in a congested port, each trip is a small gamble on whether the berth will still be accessible when you arrive. Consolidating to one or two delivery windows, with everything loaded together, cuts the number of touchpoints and tightens the timeline.
This does require advance planning. We typically advise vessel agents to finalise the consolidated requisition at least 36-48 hours before ETA. Anything later and we are negotiating against the supply-chain clock.
Alternative berthing and Ennore overflow
When Chennai is under pressure, Ennore Port (Kamarajar Port) often has better availability - especially for bulk and LNG vessels. Our operations team is set up to shift a scheduled Chennai delivery to Ennore if the berthing plan changes last-minute. The only real cost is about 30 minutes of additional road transit; the paperwork carries over. Kattupalli Port has similar flexibility for container vessels when Chennai container terminals are fully booked.
Fleet managers who plan rotations that treat these three ports as a single supply region, rather than three separate calls, retain scheduling optionality that pure-Chennai rotations do not have.
Communication cadence that actually works
The last lever is how often the vessel, agent, and chandler talk to each other during a congested call. Once every six hours is the minimum. In a genuinely busy window, every two hours from six hours before ETA until post-delivery. Status pings that read "No change, still at anchor" are more useful than silence because they confirm nothing has moved and everyone's clock is still synchronised.
None of this is glamorous. It is the operational discipline that separates a 4-hour gate-to-gangway time from a 14-hour one. In Chennai, where congestion is a periodic fact, that difference is the one that ends up on the agent's performance report.
