CTM is a service where cash is provided to the ship's master to pay for expenses incurred during the voyage. The cash is usually provided in the form of the local currency of the port the ship is visiting.

As you mentioned, your company provides CTM deliveries in both Euro and US Dollar currencies. It's important to note that the amount of cash provided is usually subject to certain limits, and the master will need to sign a receipt for the amount received.

The delivery of CTM can be arranged any day of the week, depending on the availability of the service. Usually, the delivery is done either directly on the vessel or at a designated location in the port. It's essential to have proper communication with the ship's agent to ensure that the delivery is made in a timely and efficient manner.
