Recently, the company’s Bulk Materials Handling Business Unit based at Rohrbach in Germany has experienced considerable success with the award of new contracts and the construction of individual machines for continuous barge unloading facilities. Some examples of machines recently installed or currently in design or under construction as well as the new development of continuous ship-unloading technology are described in the following article.
SECOND HIGH-CAPACITY CONTINUOUS BARGE UNLOADER FOR INDONESIA
2012 is the year for Indonesian CBU, besides the installation of a CBU at Bontang, another order was received for a 3,000tph (tonnes per hour) continuous barge unloader (CBU) for coal; destined for Kalimantan on Borneo. It will be the third CBU operating in Indonesia, designed and built by TKF.
The Arutmin North Pulau Laut Coal Terminal, PT Nusa Tambang Pratama, a company of the well-known Bakrie Group, recently placed the order with TKF. One deciding factor for this decision was, amongst others,TKFs’ excellent track record of more that 50 continuous ship and barge unloaders in operation worldwide; some of these have been in service for more than 25 years.
This latest CBU is designed for unloading 8,000dwt to 10,000dwt open coal barges at a rate of 3,000tph or 3,500m3/h. TKF received in 2008 the order for a CBU with an unloading capacity of 4,000tph. This unloader, operated by PT Indominco Mandiri, has now been successfully in operation at Bontang, also in Kalimantan, since the beginning of 2010. Seeing the satisfactory performance of this machine in operation was perhaps what finally convinced the client that the TKF type of CBU design was the right choice. However, not only their high unloading capacity, travelling mobility, low maintenance and installed power and energy consumption (compared for example with the screw-type ship unloader or a conventional grab unloader), but also the
efficiency of emptying the hull right down to the bottom of the barges without the use of a Bobcat, and thus making ‘sweeping’ of the barges
practically superfluous, are a special advantage of the TKF type of continuous barge unloader.
TKRT, Business Unit Materials Handling, better known in former days as PHB or PWH, first developed the bucket elevator type of continuous ship unloader (CSU) at the beginning of the 1970s. Its first CSU, designed to unload asbestos, was commissioned in 1974. It took some years before customers, who until then had been working with conventional grab-type ship unloaders, saw the advantages of a CSU compared with the conventional grab type used mostly in those days. Since then however, the TKF type of CSU has made its mark in the field of dry bulk ship unloading. Today TKRT CSUs are designed for handling such products as coal, iron ore, phosphate, urea, sand unloading bulk carriers of up to 250,000dwt. In recent years, in particular in countries which depend heavily on importing their fossil fuels, coal fired power plants are invariably built directly at deep water sea locations with the convenience of having their own coal unloading terminal facilities. Two such coal-fired power plants for example, are the Tanjung Bin and Jimah power stations in Malaysia. Here four TKF CSUs are in operation. Another prime example is the Hou Shi Power Plant in Fujian Province, P.R.of China, where three TKF CSUs are in operation. However, also large coal import terminals, for example in China, have in the last ten years turned more and more to using CSUs. To date, TKF has already supplied in total 15 CSUs to China. In South Korea there are already nine TKF-designed CSUs in operation in coal-fired power plants.
2. FOLLOW-UP ORDER FROM BAOLIHUA NEW ENERGY POWER CO., LTD, GUANGDONG, CHINA
In 2012, the Zhu Jiang Power Plant began the expansion project of Phase II for the other 1,000MW block. For that expansion, and in favour of the environmental protection and high unloading efficiency, the client placed an order to TKRT for two chain bucket elevator CSUs.
The contract was awarded in June 2012 for the supply and installation of two CSUs. These unloaders were designed for an unloading rate of 1,500–1,650tph, with ship sizes up to 70,000dwt, and in the future for 100,000dwt representing outstanding success of TKF in China by covering >75% of market share.
Since April 2014 these two CSUs have been operating successfully for coal unloading.
Further to this success story,TKRT won a new contract through an international tender for the new chain bucket elevator
CSU, for the
Co. Ltd. Of
will be designed for an unloading rate of 2,000–2,200tph and ship sizes up to 100,000dwt representing the third-largest CSU for coal in
China, while the others supplied to Huayang PP in China in 2007
and Huilai PP in China in 2010.
For ThyssenKrupp, this
follow-up order not only means
being awarded a further order,
but also represents continuity
with respect to design, supply,
construction and management
and demonstrates the client’s
appreciation of and satisfaction
with TKF’s performance to
The delivery to site and
commissioning of the new CSU
is schedule for April 2017.
Commercial operations can
start from June 2017.
The decision of Baolihua New Energy Power Co., Ltd to choose TKRT as supplier for all of its important ship unloaders
has been made with confidence in TKF’s advanced technology,
capability of execution of large
scale projects and first-class
technical service, as one of the
decision makers said, the choice
went in favour to TKRT after
accurate comparisons of several
competitors on the evidence of:
- worldwide and extensive
experiences in the development
of coal ship unloader technology;
v excellent performance of
CSUs already built;
- high availability and long
service lifetime without intensive
- reliable technical services during construction, commissioning
and operation period; and
- good relationship
of the world’s leading
CSUs, has once again
contributed to the
China’s coal ports
and power plants
along with other
equipment of more
than 60 machines for
car dumpers, ship
