Pile hammering at the Rampion Offshore Wind Project
Pile hammering at the Rampion Offshore Wind Project
06 October 2016  

Two Cranemaster shock absorbers (1000 T and 700 T) are currently out on mission preventing pile runs during installation of monopiles at the Rampion Offshore Wind Project off the south coast of England.

Sudden free fall of the piles during pile hammering due to layering in the soil, so called pile runs, is an increasing concern in the industry. The snap loads following pile runs can be very high, exposing both personnel and equipment to high risk. Cranemaster shock absorbers will reduce the snap loads to an acceptable level. As a result, risk is reduced, and expensive interruptions in the piling process can be avoided. 


Ready for pile hammering - potential shock loads from pile runs will be absorbed by the Cranemaster unit.

Cranemaster launching world’s largest passive heave compensator

02 September 2016  

We have now extended our fleet of units with the world’s largest PHC. Safe working load (SWL) for the new unit is 1000 T and maximum stroke length is 4000 mm.

The new unit comes with an advanced control system that adapts to the various lifting phases during operations. As a result, optimized performance can be achieved for each stage of the lift. This is particularly useful for deep water operations and splash zone crossing of demanding structures. The ability to give optimal performance allows this unit to complete subsea lifts in higher sea states than a traditional PHC.

“As offshore installations have become more complex and structures heavier, we have responded to the demand for higher capacity by developing the world’s largest PHC” Oddbjørn Bergem, CEO Cranemaster

Adaptive Cranemaster unit in deep water outside West Africa
Adaptive Cranemaster unit in deep water outside West Africa
29 March 2016  

Operations in deep water areas, e.g. outside West Africa and Brazil, put strong demands on the equipment to be used. A common challenge when using passive heave compensators in deep water, is the deep water pressure pushing the piston back in, resulting in reduced efficiency of the system. Our adaptive Cranemaster units remove this problem.

Our technology was recently demonstrated outside the Ivory Coast, where an adaptive Cranemaster unit contributed to successful installation of a 50T suction pile for the Boabab Phase 3 project. The Cranemaster system worked as expected during the whole lowering process. The suction pile was safely deployed through the splash zone, lowered through deep water, and installed at the seabed. No snap loads, no lowering resonance, and controlled landing contributed to the success.

 

 

 

Heave compensation during external turret mooring repair
Heave compensation during external turret mooring repair
29 March 2016  
Application areas for Cranemaster technology are numerous. In this current operation off the African west coast, a Cranemaster unit was used during maintenance operation on an FPSO external turret mooring structure. As part of the maintenance operation, a swivel should be exchanged. While exchanging the swivel, a strand jack was used to hold together the structure. To compensate for motions in the turret caused by heaving of the FPSO, a Cranemaster unit  was applied as part of the strand jack rigging (see Fig. 1).
 
The use of our Cranemaster unit enabled a smooth and robust exchange of the swivel, and contributed to safe and successful maintenance operation. Fig. 2 shows how the turret structure is carried by the rigging of the Cranemaster unit and the strand jack, during the swivel replacement operation.

18 December 2015  

With the use of two large Cranemaster units of 700T and 400T SWL, the wave energy device bioWAVE was recently installed near Port Fairy, Victoria, in rough weather conditions. The two Cranemaster units functioned perfectly, resulting in reduced DAF in the splash zone and reduced landing speed for the large bioWAVE. According to Mr. Kay, CEO of ARENA, this project is a major achievement for Australia’s emerging wave power industry and represents a breakthrough in renewable energy innovation.

Our latest version of adaptive PHC technology is now ready for the market. Depending on the type of unit, additional functionality such as piston locking, splash zone optimization, sea bed landing optimization, depth compensation, temperature compensation, weight compensation, and logging of movements and forces may be provided. This increases flexibility, reduces need for sub-optimal setup, and improves the performance of the units. Please view our description of our adaptive systems or contact us for further information.

Our fleet of depth compensated units is increasing
Our fleet of depth compensated units is increasing
10 September 2015  

As operations in deep waters are becoming increasingly important, Cranemaster continues to invest in units equipped with depth compensation systems. For standard units, the hydrostatic pressure on the piston rod will reduce the subsea stroke, and non-optimal settings are therefore normally required. With a depth compensated system, stroke will remain constant independent of depth.

Two different principles may be used to compensate for the depth. The first principle is based on releasing pressure in the active accumulators, typically controlled by valves and sensors. The other principle is based on a mechanical compensation, where one or more pistons having the same area as the main piston are balancing the force.  A combination of the two principles are also used. The pressure release system aditionally compensates for temperature variations and changes in buoyancy, while the mechanical system excels in its simplicity and ability to compensate for ultra deep water.

Cranemaster offers systems with all depth compensation options. The mechanical depth compensation system is covered by US patent 7934561 “Depth Compensated Subsea Passive Heave Compensator”. InterMoore Inc, the owner of the patent, has granted an exclusive worldwide right for the use of the patent to Cranemaster.

Recovery of stuck pile hammer
Recovery of stuck pile hammer
10 October 2014  

During installation of suction piles, environmental condition lead to a pile hammer got stuck in the sea floor. Within a few hours, a Cranemaster CM2-250T-2500-A unit was mobilized and sent to the closest port for mobilization. The Cranemaster unit was connected between the hook and the pile hammer, and the system was put under tension, efficiently de-coupling the movements of the boom tip from the grounded pile hammer. The pile hammer was successfully recovered without damage to crane or equipment, and pile operations could continue as planned. See here for more info on subsea recovery.

Efficient installation of GRP covers
Efficient installation of GRP covers
09 September 2014  

Over the summer, Cranemaster equipment, technicians and analysis personell have been busy working on a large GRP cover installation project. More than 30 GRP covers of different size and shape have been successfully installed. By utilizing different Cranemaster units, the marine contractor could conduct the installation operation despite varying weather conditions. Our analysis personell made an extensive analysis of the splash zone crossing and subsea landing phase prior to the operations. Reports from operational personnel onboard were positive, commenting that installation of the covers could be done safely and efficiently; the covers had no undesired movements during the subsea landing.
