Under development at Terex Cranes in Germany is a spectacular new boom system to vastly increase the capability of the 1,600 tonne capacity CC 8800-1 lattice boom crawler crane,IC has learned exclusively.
Information seen by IC indicates that in certain long boom combinations the capacity increase with the new Boom Booster option is 90 % or more, i.e. virtually double that of the standard boom set up. At short radii, where this machine is typically used for erecting refinery vessels, wind turbines and similar heavy and tall or high structures, this will be a huge advantage. It will allow heavier components to be lifted from ground level where it is safer to do the assembly work.
Back in the 1990s, a team of visionaries started planning a floating city of 50,000 to 100,000 people, with shops, restaurants, and other amenities, that would travel the globe and let people spend their entire lives at sea.
Named Freedom Ship International, the project was the brainchild of a Florida engineer named Norman Nixon. “As soon as we get this joker built we’re going to retire and live on it for two years,” he bragged in 2002.
That never happened. The ambitious project struggled to attract venture capital and was abandoned after the financial crisis. Nixon himself passed away last year. Things could be about to change for Freedom Ship International, however. Roger Gooch, part of the original team that worked with Nixon, recently sensed a change in the economic climate and decided to try to revive the idea. Gooch, 60, is a marketing man by training (he also formerly owned an insurance company and worked in the travel industry), so he thought he’d do what he did best and get the idea some press. After a few interviews, the idea was back in the spotlight again.
“It’s gone viral on the Internet,” Gooch told Business Insider with a laugh. “In the last three or four days we’ve been inundated with emails and responses and stuff, most of them have — quite truthfully — been very favourable.”
The press is important, Gooch explains, as the company needs to get past the biggest hurdle — the truly astronomical price tag of the Freedom Ship. Gooch estimates that the project would have a budget of $US9-10 billion ($9.93-11.0 billion), but he says it would provide a good return on investment.
Thanks to the new-found attention, Gooch says, a number of private investors have contacted him about the idea, though no venture capital firms have reached out so far. He says his team is now interested in partnering with “notable or established private maritime entities” and has also floated the idea of what he called a “constructive equity capitalisation” — wherein the vendors he would use to construct the Freedom Ship would be given equity in the finished product for discounts of services and goods.
The plans for the Freedom Ship are certainly audacious. The 1.6km-long and 25-storey-high ship would circle the planet every two years, spending roughly 70 per cent of its time moored outside major cities and ports (it will be too big to enter most ports, so residents can fly to and from the shore from the Freedom Ship’s onboard airport).
On board, the floating ship would have its own economy, with tens of thousands of people working in shops, bars, and other businesses, and everyone on board paying a maintenance fee to support infrastructure such as security services and fire fighters.
Gooch is adamant, however, that the project is feasible, and points out that technically the idea of a city on a boat is a misnomer — the Freedom Ship is actually a “super platform”.
All NBR crawler transporters are developed in such a way, that the load is supported by a hydraulic compensation cylinder in the center of the transporter. In this way the NBR crawler transporter can be driven under any support point of the load to be moved.
With the hydraulic support cylinder the load can lifted from the building supports and be equalized between three crawler transporters and moved in a synchronized mode and make turns as needed. Max stroke of suspensions cylinder is 400 – 680 mm (depending on type selected).
The building heights vary between 1500 and 2250 mm. PowerPack cap. is between 240 and 580 Kw. Under full load the max. speed is 0.53 km/hr.

Contractors need to be able to count on reliable and durable construction equipment when building large structures – they know that technical failure and downtime can lead to delays and higher costs.
From dams on the River Nile to new sports stadiums in the Amazon, equipment manufacturers and contractors are working to ensure large projects stay on schedule.
As well as general earthmoving and lifting machinery, specialised construction equipment models are available to tackle big projects. Falsework and formwork manufacturer Doka, for instance, has launched new specialised formwork just for dam construction, while XCMG teamed up with Chinese petrochemical company Sinopec to develop a huge 4,000 tonne capacity crawler crane for extreme lifting jobs.
The XGC88000 crane made its debut lift at the Wanhua Industrial Park in Yantai, China, where it was tasked with hoisting a 118 m tall, 1,680 tonne propylene production tower into place. The crane’s 108 m boom and 33 m fixed jib were used in a 30 m operating radius.
Developing the machine is one thing, but delivering it onto a remote construction site is another question entirely. Co-ordinating the movement of materials and equipment around a large structure jobsite can be a major challenge, and a highly organised approach is crucial to keep things moving efficiently.
In South America, for instance, equipment from Terex and its sister brand Genie is supporting construction of the final stages of the 45,000 seat Arena da Amazonia Stadium in Manaus, the capital of the Brazilian state of Amazônia.
Set to host four matches during next year’s FIFA World Cup, the stadium is being built by a trio of contractors – Andrade Guitierrez, ENTEC, and Tomiasi – and was designed by GMP Architekten.
The stadium’s most striking feature is its self-supporting roof, construction of which is currently underway. Made from over 200 pieces of steel and weighing over 6670 tons (6500 tonnes), the roof structure will consist of mutually supporting cantilevers with steel hollow core girders. The largest individual components are 22 m long and weigh 30 tons (27 tonnes).
Royal Dutch Shell PLC says it has completed building the hull of the world’s largest floating facility, which has been constructed to process natural gas off the coast of western Australia.
An uncomfortable prospect for global exporters of liquefied natural gas (LNG) will unfold this week — buyers from countries that import 70% of the world’s LNG will meet to discuss how to get a better deal. Keep reading. Keep reading.
Shell said Tuesday that the 488-meter (1,600 foot) hull of the structure, known as “Prelude,” was floated out of the dry dock in Geoje, South Korea where it is being built.
With a bow and stern half a kilometre apart, four football pitches would fit on the vessel’s deck were it not for a clutter of kit towering up to 93 metres high that will take in the equivalent of 110,000 barrels of oil per day in natural gas and cool it into liquefied natural gas for transport and sale in Asia. It will float above gas fields.

This vessel is a key component for the realisation of the Ichthys gas-field in north-western Australia.
Due to its partly open bottom in combination with large air compressors and air vent valves, a tidal difference can be compensated up to 6-8 m, depending on cargo weight

The incident occurred just before 8:00 this morning and thankfully the operator was on the ground, and not in the elevating operators cab. He was apparently in the process of lifting materials onto the roof at the time.

Description: Construction of the biggest and strongest crane in the world, TAISUN. Designed and built by Yantai Raffles Shipyard and located in Yantai, Northern China. The crane marks a new era in offshore construction by allowing offshore vessels to be built in two halves that both can be built on the ground.
