Economy of scale is the cost advantages that an enterprise obtains due to its scale of operation (typically measured by the amount of output produced), with cost per unit of output decreasing with increasing scale. Economies of scale apply to a variety of organizational and business situations and at various levels, such as production, plant, or an entire enterprise. When average costs start falling as output increases, then economies of scale occur. Another source of scale economies  is the possibility of purchasing inputs at a lower per-unit cost when they are purchased in large quantities.

Time charters The charterer has the use of the ship for a specific trip or a period of time.

Charterers may direct the vessel within the trading limits agreed, and, in normal circumstances, the Master must obey these orders.

Whilst the time charterer has the commercial control, the owner retains responsibility for the vessel and the Master and crew remain in their employment.

The hire, usually calculated per day, is paid in advance at regular, agreed intervals, normally semi-monthly or monthly.

Whilst on time charter, the time charterer usually pays for all port charges including their own agency fees, canal dues, pilotage, and generally (if not covered elsewhere) cargo insurance.

Normally, the charterer pays for the fuel onboard at the time he accepts delivery and for fuel supplied while the vessel is on hire. When the vessel is redelivered the owner pays for bunkers remaining on board. The prices applicable on delivery and redelivery and the respective quantities are normally agreed by negotiation.

The owner pays for the operating expenses of the vessel.

If the ship breaks down or, as a result of the shipowner’s fault, the charterer does not have the use of the vessel, the vessel goes ‘off-hire’ for that period subject to any terms in the Charterparty.

Time charterers may be owners who want to temporarily augment their own fleet, charterers who have a variety of commitments to meet, charterers who believe term chartering will hedge the market, operators who foresee a profit by taking voyage contracts from charterers and time chartering vessels themselves to cover those contracts.

Time Charter Trip A trip time charter is a comparatively short time charter agreed for a specified route only (as opposed to the standard time charter where the charterer is free to employ the vessel within agreed trading areas).

The owner pays for fuel and operating expenses, and (generally) port disbursements, of the vessel.
