As companies operating in heavy industries continue to face highly competitive markets, Mammoet has recognized the valuable role lifting operations can play in improving economies of scale and cost effectiveness. Understanding that crane capabilities in these industries can contribute significantly to a project’s efficiency, Mammoet developed the Focus, a concept for a new type of heavy lifter that will revolutionize the way plant owners and EPCs think about construction efficiency, plant maintenance and turnarounds.

New principles of crane construction stretch the limits of modular construction and redefine plant turnaround efficiency

Following the concept announcement in September 2016, Mammoet conducted further consultation with its customers, realizing their need for greater lifting capacity and ease of maneuverability with fast (de)mobilization, particularly in limited and congested spaces. 

The feedback led Mammoet to extend the concept even further, devising two types of Focus cranes, the A-Frame Focus and the Y-Frame Focus, which will significantly benefit the FPSO market and those operating in the upgrades and maintenance of existing plants. 

A-Frame Focus

The A-Frame is designed to lift much heavier and larger modules in confined spaces. It’s capacity is second to none in the lifting industry. This new found efficiency in delivering module construction at ever larger scales will be a valuable asset to the FPSO market, providing significant project optimization and time saving benefits.

A Frame

The capacity of the A-Frame Focus creates new possibilities for project optimization and efficiencies in modular construction, particularly in the FPSO market.  

 

Y-Frame Focus

Combining much greater lifting capability, versatility and reach, the Y-Frame is the ideal lifting machine for use in plants with complex infrastructure and space limitations. It’s ability to be built up vertically and maneuvered with flexibility in very limited or congested areas will have a powerful effect on the efficiency levels of plant upgrades, maintenance and turnarounds.

The Y-Frame Focus has the capacity, versatility and reach to work in and around different plant layouts. It requires a minimum amount of space – starting at 22 x 22 meters of surface – making it ideal for efficient project execution in congested plants.  

With the introduction of the Focus, Mammoet has redefined the principles of crane fabrication and assembly. Some key innovative features of the Focus and their advantages are outlined below: 

Due to the self-erecting principle, the back mast can be built up at the same height as or even higher than the main boom, which can significantly increase the lifting capacity for long back mast length and overall versatility of the crane.

Due to the innovative vertical assembly method, the Y-Frame Focus can be fully assembled from an extremely small base.
