Tanker AB work is different from bulk carrier or general cargo AB work in ways that matter practically. The pay is better, the operations are more specific and the risks are more defined. Here is what the job actually involves on a tanker.
The Cargo Environment
A tanker carries liquid cargo. The deck is a network of pipes, valves, manifold connections and tank lids rather than hatch covers and crane rails. During cargo operations, ABs have a specific role that does not exist on dry cargo ships.
On a crude tanker the AB monitors manifold connections for leaks, operates tank lid valves under instruction, watches gauges during loading and discharge. The work requires attention because a valve in the wrong position or a connection that starts leaking is not a minor issue on a vessel carrying crude oil.
On a product tanker the cargo operations are more varied. Multiple grades in separate tanks. The AB who understands why cargo grade separation matters and why tank lids need to be in specific positions at specific stages of loading is more useful than one following instructions mechanically.
On a chemical tanker, up to twenty different cargoes simultaneously on parcel vessels, the cargo officer relies on ABs who are fully present during operations. Missing a valve position or overlooking a manifold connection on a chemical tanker is a serious problem.
The Pump Room
Most tankers have a pump room housing the cargo pumps that discharge liquid cargo ashore. Entering it requires atmosphere testing, a permit to work, and never going in alone. Pump room incidents have killed seafarers and the procedures exist because those incidents happened.
ABs who understand why the pump room procedures are not optional become better tanker ABs faster than those who treat them as paperwork.
The Certificates Required First
Basic Training for Oil and Chemical Tanker Cargo Operations. Three to five days at an approved training centre. Without it, no tanker operator will consider the application regardless of sea service record. This is the first investment that opens the tanker sector.
Getting the First Tanker Contract
Product tanker operators accept experienced general cargo or bulk carrier ABs with the endorsement more readily than crude or chemical tanker operators.
One product tanker contract changes the entire application profile. After it you are an AB with tanker experience rather than a dry cargo AB applying to tankers. That distinction matters significantly to operators and agencies.
