Whitepaper – Offshore Feedering: Supporting Global Energy Transition Practically Using feeder barges to supply wind turbine components to precious offshore installation vessels seems like a no brainer. But why shuttle cargo with your most expensive and time-critical piece of equipment? While becoming more common practice in near shore and benign environments, the industry has yet...
Heavy complex machinery
Our engineers are familiar with the mechanics of heavy equipment. Huge mobile cranes, piling rigs and big A-frames for dredging equipment are within our mechanical portfolio. From concept sketches to the final welding specification: we can cover all your needs.
Together with the team of the client we develop and design heavy machinery. We start with a kick-off, which is always a team effort to get a clear specification and list of requirements: the Basis of Design (BoD).
Secondly, the Eager.one team will work out a concept for further evaluation with the client: Is this the right solution? Is this concept the right translation of the BoD into a working piece of equipment?
Having all parties satisfied our engineers can now complete the next phases up to the detailed design and construction drawings. Thorough checks and verification, using state of the art design and FEA software, guarantee the fit for purpose of the unique machine. Our engineering deliverable includes operations manuals, capacity charts, as built drawings and test protocols. All prepared for further certification and CE marking.
In the majority of the design projects the standards used will be agreed in the early stages of a project. Our engineers have in-depth knowledge of almost every design standard, from EN standards to offshore standards from Lloyd’s or DNV-GL and more.
Cranes and piling equipment
Since 1979 we have continuously expanded our knowledge about the design of mobile cranes and piling equipment. We have combined the most valuable learnings and used these to develop our own design software and system. That way, we can guarantee the best results.
We are familiar with all aspects of crane design, incl. boom systems, under and upper carriage. Our team has designed a wide array of crane types like mobile cranes, crawler and ringer cranes, fixed offshore cranes and more.
And, as an independent player, we have worked with many crane brands and types. Both the in-depth theoretical know-how and the operational experience of our engineers, will truly add value to your team.
We have developed a unique and refined package of design services specifically for the piling business. Basically we consider a piling rig as an extension of a mobile crawler crane. Our team is proficient at calculating the stability and strength of any type of piling machine. We would love to inform you about special applications, upgrades or assist you with requests for information.
We are often asked if we see a possibility to get a little bit more out of an existing crane configuration. With our specific and unique design software for cranes, we are able to determine if the basic design of a mobile or fixed crane has reached the ultimate limit, according to the legal standards.
You do not have the design information available or you want to modify specific unique components? No problem!
We will examine the existing rig in the field, acquire all relevant information and make sure the design fits perfectly into the existing machine. And Eager.one does not stop with a general arrangement. All detailed design of any crane component is part of our deliverable.
Calculation of crane capacity charts
We have developed our own design software in-house, which enables us to calculate capacity charts for all types of cranes, independent which brand.
With our in-house design software STERK©, we calculate capacity charts for all types of cranes. Our software is independent from any crane brand or type. And even the charts for telescopic cranes or heavy ringer cranes can be calculated. STERK© also calculates 2nd order effects, which makes it perfectly suitable for the calculation of charts for extreme long booms and jibs.
The use of offshore cranes is often limited by the ocean dynamics and sea states. With our software we are well equipped to calculate the capacity chart for offshore cranes in dynamic environments, various sea conditions and the limiting demands from certification bodies.
A mobile crane is often not designed to cope with offshore and near shore environments. We know how to overcome the resulting challenges: by calculating the special charts for this combination, considering the limited forces in the critical components.
Operators are often looking to gain a 10-15% more capacity in the chart to get a job. We gladly offer a helping hand. Our engineers work with STERK©, used to calculate the limits in crane design. This maximizes the crane capacity within the required safety standards.
