2.26:
-
"2.27 Ship engaged in anchor handling operations means a ship engaged
in operations with deployment, recovering and repositioning of anchors and
the associated mooring lines of rigs or other vessels. Forces associated
with anchor handling are generally associated with the winch line pull and
may include vertical, transverse, and longitudinal forces applied at the
towing point and over the stern roller.
-
2.28 Ship engaged in harbour towing means a ship engaged in an
operation intended for assisting ships or other floating structures within
sheltered waters, normally while entering or leaving port and during
berthing or unberthing operations.
-
2.29 Ship engaged in coastal or ocean-going towing means a ship
engaged in an operation intended for assisting ships or other floating
structures outside sheltered waters in which the forces associated with
towing are often a function of the ship's bollard pull.footnote
-
2.30 Ship engaged in lifting operation means a ship
engaged in an operation involving the raising or lowering of objects using
vertical force by means of winches, cranes, A-frames or other lifting
devices. Fishing vessels shall not be included in this definition.
-
2.31 Ship engaged in escort operation means a ship
specifically engaged in steering, braking and otherwise controlling of the
assisted ship during ordinary or emergency manoeuvring, whereby the steering
and braking forces are generated by the hydrodynamic forces acting on the
hull and appendages and the thrust forces exerted by the propulsion units
(see also figure 2.8-1).
