人们经常广泛讨论何时起算装卸时间这一话题。因此，本文旨在简要概述起算装卸时间（或发生滞期）需满足的条件，同时提及作为指导原则的重要支持性判例法。
一般来说，在大多数租船合同中，需要满足以下三个条件才能起算装卸时间：
1. 船舶已经到达租约约定的地点；
2. 船舶各装卸设备均准备就绪，且处于适合装卸货物的状态；
3. 船舶须递交有效的装卸准备就绪通知书(“NOR”)，以确保船舶到港和准备就绪。
一旦满足了这些条件，该船舶视为“到达船舶”，将开始按照租约起算装卸/滞期时间。我们将依次讨论这三个条件。

A brief history of laytime
The subject of Commencement of Laytime is extensive. Therefore, this article is intended to be a brief overview of the main conditions that are generally required for laytime (or, if applicable, demurrage) to commence, together with references to the significant supporting case law underpinning the guiding principles.
In general terms, there are three conditions which need to be satisfied under most charterparties before laytime can commence. These are:
1. The vessel must have arrived at the destination specified in the charter;
2. The vessel must be ready in all material respects and in a fit condition to load or discharge the cargo; and
3. Where required, the vessel must tender valid Notice of Readiness (“NOR”) confirming the vessel’s arrival and readiness.
Once these conditions have been met, the vessel is an “arrived ship” for the purposes of the contractual laytime/demurrage regime, and time will begin to run. We will consider each requirement in turn.
