above the subsea load with a sling. Shackles at both

ends are included.

LOADRANGEThe subsea CRANEMASTERSlifting capacitytypically range from 2-500 tons. Higher capacity

CRANEMASTERSwill be designed if required. Several subsea

CRANEMASTERSmay be used in parallel or in series.

THECRANEMASTERSYSTEM

CRANEMASTERis a proven and extremely

cost-effective system to reduce the dynamic loads,

significantly increase the offshore lifting capacity and

increase the operating life of offshore cranes.

WORKINGPRINCIPLES

CRANEMASTERconsists of a passive compensator and a

double acting hydraulic shock absorber as one

self-contained unit. No need for external power

supply.

ARRANGEMENT

CRANEMASTERcan be supplied for the

following applications:

For permanent mounting on the crane boom.

For whip line with all accessories

(swivel/hook and wire connection)

For main hoist with all accessories

(shackles, sling and hook)

LOADRANGE

The CRANEMASTERfor offshore cranes can be

custom-made to fit your needs. Typical range is from

2-500 tons. If necessary, several CRANEMASTERS

may be used in parallel.

APPROVAL

Lloyds Register and DNV have approved the ratingprocedure for offshore cranes with CRANEMASTER.

INCREASEDOFFSHORELIFTINGCAPACITY

CRANEMASTERgives a significant increase

(up to 2-3 times) of the offshore lifting capacity within

the original crane design specification.
