When should we use the pilot and the accommodation ladder at the same time?
When the vertical freeboard to the water level is more than 30 feet (9 meters), a combination ladder arrangement, consisting of a pilot ladder and an accommodation ladder at the same time, is normally used. The reason for this is that a fall from more than 30 feet (9 meters) into the water is considered mortal.
What is the length of pilot ladder?
A combination ladder should be prepared for the pilot when the freeboard of the vessel exceeds 9 meters. The gangway should not be closer than 4 meters (roughly 12 feet) above the water. The pilot ladder should be 1.5 meters (5 feet) above the water (unless otherwise instructed by the pilots).
