A pilot vessel can sound an identity signal when it is approaching a ship to indicate its presence and intent to provide pilotage services. This signal typically consists of a series of short blasts on the vessel's horn, helping to identify it as a pilot vessel to other vessels in the vicinity. The signal is important for ensuring safe navigation and communication in busy waterways. Additionally, it can be used when the pilot vessel is departing from the ship after completing its duties.
In fog, a pilot vessel is required to sound one long blast followed by two short blasts on its whistle at intervals of not more than two minutes. The long blast indicates the vessel's presence, while the two short blasts signal its role as a pilot vessel. This sound signal helps other vessels in the vicinity to identify the pilot vessel's location and intentions in reduced visibility conditions.

None. A vessel underway under normal conditions does not need to make any sound signal.If the vessel ceases to make way it still does not make a sound signal unless special circumstances apply.
The sound signal short-long-short is an optional, additional signal made by a vessel at anchor in restricted visibility. The signal may be made by such a vessel in addition to her required sound signal to give warning of her position and of the possibility of collision to an approaching vessel.Collision Regulations 35(g)
In restricted visibility, a power-driven vessel underway is required to sound one prolonged blast every 2 minutes. This signal is meant to indicate the vessel's presence to other nearby vessels in low visibility conditions. The prolonged blast lasts for about 4 to 6 seconds. This sound signal helps enhance safety by alerting others to the vessel's location, allowing for better navigation and collision avoidance.
To indicate that you want to pass another vessel on your starboard side, you should sound one short blast on your horn or whistle. This sound signal communicates your intention to the other vessel, allowing them to understand your maneuver and adjust their course if necessary. It's essential to follow this convention for safe navigation and to avoid potential collisions.
In restricted visibility, a power-driven vessel underway is required to sound one prolonged blast every two minutes. This signal alerts other vessels to its presence and intentions. Additionally, if the vessel is making way through the water, it may also sound two short blasts after the prolonged blast.
