The Laytime

It is clearly important to determine when laytime commences since this is the key to the division of responsibility for the time spent at the load and/or discharge port. Most charterparties require the owners to serve a notice of readiness at load or discharge port stating that the vessel is ready in all respects for cargo operations, the notice of readiness constitutes the contractual step which is required to trigger the commencement of laytime. Due to this, charterparties usually contain provisions which stipulate when notice of readiness may be contractually served and when laytime commences once notice of readiness has been validly served.

Reversible Laytime

In voyage chartering, permitting charterers to add up the laytime allowed for loading and discharging is called Reversible Laytime. In other words, any time saved (or exceeded) at the load port can be carried forward to the discharge port. Depending on the drafting of the relevant clause, charterers may only have a limited period of time for deciding whether to reverse.

Draft alterations depend on water density

Good day

It happened that I forgot the formula for the calculation of vessel's draft at different water density, though I searched the Internet and found nothing in English. So I decided to translate the article, which I found in Russian.

When the vessel passes from one water basin to another, the salinity (seawater density) changes.  It's very useful to know the way vessel's draft will change. And for the determination of vessel's draft delta we will turn to physics.

CP proformas

Earlier I have wrote about what is a Charter Party. And now it's time to make a list of different CP proformas for easy reference. The list will be kept here and it will be updated from time to time.
