The master must keep on board the vessel a rigging plan, drawings and instructions for the use of any derrick used in loading or unloading.
2 Use of stays
For a derrick used in loading or unloading, any stay, including a backstay or preventer stay, that counteracts a load on a mast or derrick post, other than a stay that must be disconnected to enable loading or unloading operations, must be fitted correctly and be taut and secure during loading and unloading.
3 Securing guys in way of deck cargo
If deck cargo is stowed against and above a vessel’s rail or bulwark, there must be a wire rope pendant or chain, extending from a ring bolt or other anchorage on the vessel, that:
(a) is long enough for derrick guys and preventers to be attached without the need for a person, engaged in loading or unloading, to go overside; and
(b) has a safe working load of at least the safe working load of the derrick guy or preventer to which it is attached.
4 Permanent attachments to a derrick
All permanent attachments to a derrick used in loading or unloading, including any ring bolt, eyebolt, padeye, lug, band or heel connection or fitting, must be strong enough to support the maximum load, as set out in the rigging plan, drawings or instructions for the use of the derrick, that may be imposed on the attachment.
5 Securing guys to a derrick
(1) Each guy, guy block or preventer guy used in loading or unloading must be secured to a derrick at a permanent attachment, with no more than 1 connection to each attachment.
(2) However, for a preventer guy, an eye that has been formed in 1 end by splicing may be placed around the derrick head so that it will not be dislodged during loading or unloading.
6 Restriction of movement of heel blocks
A derrick heel block that is subject to movement in the vertical plane between load and no-load positions must be fitted with a device that constrains the movement consistent with safe operation.
7 Securing runners
A runner used in loading or unloading must be attached to the winch drum:
(a) so that no part of the runner is damaged; and
(b) by means other than fibre rope.
Note 1 The method used to secure a runner to a winch should be by shackle or clamp-type socket, any of which should provide a strength equivalent to 50% of that of the runner.
Note 2 The number of complete turns remaining on the drum of the winch if the complete working length of rope has been paid out should not be less than:
