Does the Polar Code replace SOLAS, MARPOL, and STCW for vessels operating in polar waters, or does it function differently?

A. The Polar Code adds an additional, mandatory layer of requirements on top of the existing SOLAS, MARPOL, and STCW frameworks — it does not replace any of them; a vessel operating in polar waters must comply with standard SOLAS/MARPOL/STCW requirements AND the additional Polar Code requirements specific to polar operation

B. The Polar Code is a voluntary alternative that vessels may choose instead of complying with MARPOL in polar waters

C. The Polar Code only applies to passenger vessels and has no bearing on MARPOL compliance for any other vessel type

D. The Polar Code entirely replaces MARPOL and SOLAS for any vessel operating in polar waters, superseding their requirements

A. MARPOL Annex I imposes no restrictions specific to polar waters beyond what applies globally

B. The HFO restriction applies globally and has no special polar-specific provision at all

C. A prohibition on the carriage and use of heavy fuel oil (HFO, generally defined by density/viscosity criteria) — in Antarctic waters this has applied for some years under MARPOL Annex I Regulation 43, and a phased Arctic HFO restriction/ban has since been adopted, reflecting the heightened environmental consequence of an HFO spill in these especially sensitive and remote regions

D. The restriction only applies to fuel actually being burned, not to fuel simply being carried as cargo or bunkers, regardless of intended use

A. Polar waters are generally subject to more stringent discharge criteria across these annexes (e.g. tighter or zero-discharge provisions in specified circumstances) compared to standard global requirements, reflecting the particular environmental sensitivity, slower degradation rates, and limited capacity of polar ecosystems to absorb pollution compared to temperate or tropical waters

B. Polar waters are subject to identical discharge requirements as anywhere else in the world under these annexes, with no special provision

C. These annexes do not apply at all in polar waters since they are considered outside the scope of MARPOL entirely

D. Polar waters have more relaxed discharge requirements than elsewhere, since lower population density reduces the consequence of discharge
