Layday: The period of time during which the owner must tender the ship for loading. The charterer is not obliged to accept Notice of Readiness before the commencement of laydays. The charterer may cancel the charter if the ship does not tender prior to the expiration of laydays (which is called the canceling date).

Laytime: The amount of time allowed at a port for loading and/or discharging.

Laytime Non-Reversible: When laytime is non-reversible, any despatch earned or demurrage incurred at the load or discharge port is payable there, and time saved at one port cannot be used to offset time lost at the other.

More or Less Owner's Option (MOLOO): An Option Type, in which the charter party will have a stated contract quantity to load/discharge, for example, 50,000 MT on a Panamax, basis 10% more or less owner's option. This means that although the contracted quantity is 50,000 MT, the owner is aware that by the time his vessel comes to load the cargo, it may not be able to load 50,000 MT. On the other hand, he may be able to load a little more. Before arriving at the loading port, the ship's Captain will declare what quantity his ship is actually able to load. This declared, or nominated, quantity must fall within that 10% range.

• If the vessel cannot load the minimum, or the cargo owner comes with less than the minimum 45,000 MT, then deadfreight is due.

• If either party goes over the maximum, then overage is calculated on the freight, which is essentially a rebate for the additional cargo loaded beyond the maximum (55,000 MT, in this case).

• The vessel must be fully prepared to load or to discharge immediately.

• Laydays commence from the moment the Notice of Readiness has been accepted by the charterer, unless (as is usually the case) stipulations to the contrary have been included in the charter. Under most grain Charter Parties, Notice of Readiness to load must be accompanied by a certificate issued by a competent surveyor stating that the vessel is ready to load in all holds.

O

OBQ: Abbreviation for Onboard Quantity.

Option Type: Cargo Tolerance Option Type, the option in the Charter Party that states the minimum/maximum load/discharge quantity for a cargo and/or which business entity has the right to declare it. If the vessel cannot load the minimum, or if the cargo owner has less than the minimum, then deadfreight is due. If either party goes over the maximum, then overage is calculated on the freight, which is essentially a rebate for the additional cargo loaded.

Ore-Bulk-Oil Carrier (OBO): A vessel designed to carry wet and/or dry cargoes, also known as a combination carrier. They were developed to be flexible enough to vary their cargo and to reduce ballast voyages.

• For a call option, the strike price is higher than the price of the underlying security.

• Special: A payment outside the regular schedule. Period-based costs, such as the Time Charter Hire, cannot be allocated this way. If the contract has no more Period payments remaining, the Invoice Type defaults to Special.

• Incremental: A payment for which a sort of reconciliation of accounts is performed. All amounts due since the beginning of the Time Charter contract are calculated, and all payments made are subtracted. The net difference then shows as the payment due. This payment method can be used either for every payment or once at the end of the Time Charter to ensure that the accounts are correct.

Period TC: A Time Charter Contract Type covering more than one voyage, but not long enough to require special accounting, as opposed to a Trip TC or a Long-Term TC.
