9 Union purchase rig
       A derrick used in a union purchase rig must:
(a) be rigged in accordance with the drawings mentioned in clause 1; and
(b) be fitted with a preventer guy of wire rope, or wire rope coupled to a length of chain, with a safe working load that is sufficient for the stresses on the derrick during loading and unloading; and
(c) have each guy used to position the derrick kept taut during loading or unloading.

10 Angle between runners of union purchase rig
       If loading or unloading by a derrick in union purchase rig, the angle included by the ends of runners at the hook assembly measured in the plane of the runners must not be more than 120° or a lesser angle in accordance with the rigging plan, drawings or instructions for the use of the derrick.

Division 2 Cranes

1 Rigging plan, drawings and instructions
       The master must keep on board the vessel a rigging plan, drawings and instructions for the use of any crane used in loading or unloading.

2 Limiting devices
      (1) A crane used in loading or unloading must have a motion-limiting device that:
(a) prevents movement of the crane, and any load being handled, beyond the designed range of operations of the crane; and
(b) operates automatically; and
(c) for a crane other than a derrick crane — takes effect by interrupting the operating power so that the crane and its load are held stationary.
      (2) However:
(a) a derrick crane that does not comply with paragraph (1)(c) must be fitted with a visual or audible alarm to warn the operator when the load is approaching the limit of the crane's range; and
(b) for a crane installed before 17 November 1986 in which compliance for its traversing, travelling or slewing motions would be unreasonable or impracticable — it must not be operated beyond its safe limits.

3 Markings
      (1) A crane for use in loading or unloading must be marked with:
(a) its safe working load; and
(b) if the safe working load varies with the outreach of the crane — the safe working load for each specified outreach.
      (2) The marking of each safe working load and outreach of a crane or derrick crane must:
(a) state the safe working load, including the units of mass used; and
(b) for a marking mentioned in paragraph (1)(b):
 (i) numerals that indicate the number of metres of outreach followed by the letter 'm', and
 (ii) an oblique stroke separating the information for each outreach.
      (3) Markings must be clearly made:
(a) on:
 (i) an external part of
