Oil tanker vs chemical tanker jobs

Tanker job comparison: oil (crude + product) versus chemical (IBC Code). Cargo handling, certificates, pay, lifestyle, and which suits which seafarer.

Side-by-side

Criterion	Oil tanker Crude (VLCC, Suezmax, Aframax) + product (LR1/2, MR)	Chemical tanker IBC Code Type 1 / 2 / 3, multi-grade voyages
Cargo grades per voyage	Usually 1, sometimes 2	3–15+ grades parcel-traded
Tank cleaning complexity	Moderate (oil-to-oil)	High (grade compatibility matrix, dedicated cleaning chemicals)
STCW certificates	Basic Tanker Training (A-V/1-1-1) + Advanced Oil Tanker for officers	Basic Tanker Training + Advanced Chemical Tanker for officers
Vetting culture	SIRE 2.0 (OCIMF)	CDI (Chemical Distribution Institute) + SIRE 2.0 where applicable
Officer pay (indicative monthly USD)	VLCC Master $14–19k; 2/E ~$10–13k	Stainless-steel chemical Master $15–20k; 2/E ~$11–14k
Rating pay (indicative)	~$1.6–2.4k AB on a VLCC	~$1.8–2.6k AB on a stainless chemical
Contract length (typical)	4 months officers / 6 months ratings	4 months officers / 6 months ratings
Routes	Long sea legs, fewer port calls	Shorter legs, frequent port calls (parcel trade)
Workload in port	Heavy at loading / discharge only	Heavy at every port — small parcels, repeated handling
Career rarity (and pay leverage)	Common	Specialist — fewer crews trained → better leverage

Who each suits

Oil tanker
Officers wanting tanker premium without the chemical-cargo complexity. Long-sea-leg comfort, sleep-friendly UMS rotations, fewer ports per contract. Good first-tanker entry from container / bulker.
Chemical tanker
Officers building specialist tanker careers — the pay leverage compounds with experience. Suits those who enjoy detailed cargo planning, frequent port calls, and the discipline of compatibility matrices.

Pros and cons

Oil tanker

Pros

Operationally simpler — one or two grades per voyage.
Long sea legs mean better rest patterns.
Larger crew (especially VLCC) — workload distribution.

Cons

Lower pay than chemical tanker at equivalent rank.
Heavier vetting pressure (SIRE 2.0) than non-tanker fleet.
Older fleet on some routes — more PSC scrutiny.

Chemical tanker

Pros

Higher pay (5–15% officer premium typical).
Specialist skill set — better leverage when changing companies.
Variety — frequent ports, different cargoes, intellectually engaging.

Cons

Demanding tank-cleaning discipline + PPE requirements.
Toxic + corrosive cargo risk; stricter ER + cargo control.
Short port calls cut into rest hours.
Smaller crew (typically 18–22) — workload concentration.

Common misunderstandings

'Chemical tanker = always more dangerous.' Risk is well-managed through CDI inspections + cargo compatibility procedures; the work is more demanding, not necessarily more hazardous.
'Oil tanker pays the most.' Crude carriers (VLCC) pay well, but stainless-steel chemical at senior ranks usually wins on $/month.
'Tanker certs work on both.' Basic Tanker Training is shared; the advanced certificates are cargo-specific — oil-advanced does not unlock chemical, and vice versa.

FAQ

Can I move from oil tanker to chemical tanker without losing rank?: Yes — your CoC carries across. You'll need the Advanced Chemical Tanker endorsement and the principal will want a few months' supernumerary or 'second 2/E' time onboard before promoting you to senior cargo-watch officer. Pay typically increases on the move.
Which has more time at sea vs in port?: Oil tankers, especially VLCC and Suezmax, run long sea legs (10–25 days). Chemical tankers parcel-trade — many port calls, often 2–4 days apart. If you want sea-time-heavy rotations, oil wins; if you want short-leg variety, chemical.
Are vetting pressures the same?: Both fall under OCIMF's SIRE 2.0. Chemical tankers also face CDI inspections (Chemical Distribution Institute). Net: chemical tanker officers face more frequent vetting in practice.
