The essential responsibilities of charterer as regards cargo under the voyage chartering are reflected in his duty to load cargo that complies with the terms of the contract in mutually agreed period of time. The time factor merges two explicit autonomous duties - the duty to have cargo in disposal and to load it in a lay-time. So the question arises as to whether there is enough space for a new obligation to intervene? The analysis made in this regard established the nature and extent of the charterer’s obligation to furnish cargo at a specific moment in time and at the agreed place. The described liability regime corresponds precisely to the autonomous duty to have a cargo in readiness and repeatedly proves that in certain cases this duty does not fall within the duty to load within the lay-days and exists independently.
