The pedestal crane shall be diesel hydraulic powered and be of type A (single piece box boom type) according to API 2C, fitted with a cab and two boom lift cylinders.

The two lift cylinders shall be capable of supporting the boom and 120% design load within recommended minimum and maximum boom angles as per Company General Specification GS EP STR 002 “Cranes for fixed offshore installations”.

Off-lead and side-lead angles shall be taken as in accordance with COMPANY General Specification GS EP STR 002 and the MLS Preliminary Metocean Design Criteria - Rev2.

The power unit shall be designed to allow 90% of the prime mover rated power to be sufficient for hoist the maximum rated load at the maximum hoist speed and simultaneously either raise the boom at the maximum luffing speed or slew at the maximum speed, whichever condition requires the greater power.

9.1.1 Environmental Design criteria

The crane shall be able to slew, boom up and down without load in order to lower down the boom onto its rest in wind speed of 25m/s. The wind speed to be taken into account shall be calculated in accordance to the elevation of the crane (elevation of the middle of the boom at maximum inclination).

For “out of service” conditions, after offshore installation, the crane shall be able to withstand the maximum wind velocity defined by 100 years 3 sec gust (i.e. 28m/s at 10m altitude).

The effect of wind forces on loads when lifting shall be calculated assuming the load is a 12' ISO standard container.

All systems and equipment shall be designed to allow crane operations at full load for 15 minutes per hour for 12 hours. Due consideration shall be especially paid to the cooling system.

The crane operating sea state is described as below;

Significant wave height (Hs) : 1.7m

The dynamic co-efficient for crane design shall be derived from Default Dynamic Method from API 2C, based on the operating condition.

The crane and its equipment shall also be designed and certified for personnel lifting according to EN 13852 Part 1.

9.1.2 Materials

Machine-welded chassis supporting mechanisms must undergo post-welding stress relieving before machining, in particular the chassis holding the directional rings of cranes.

In the case of crossed crane booms, the centerlines of the neutral fibbers of the elements must intersect at the assembly knots; any other arrangement must be submitted to the CONTRACTOR for approval; weld joints must be special quality.

Maximum deflection of the beam on two supports shall be less than L/500 with L = span between two supports unless otherwise specified. Same criteria shall be used for a cantilever beam.

The assemblies of elements that must be dismantled for transport are to be made by bolts or by joining pins with cutter pins; in the case of cuttered joining pins, no play that might cause battering and introduce additional shocks and stresses is allowed; the battering pressure must be low enough with respect to the characteristics of the material not to cause any incrustation that would prevent the withdrawal of the joining pins.
