2804 – 750 t/h OFFSHORE CONVEYOR BELT SYSTEM FOR TRANSHIPPER “BULK KREMI” WITH CONTINUOUS SHIP LOADER (CRUSHER & PRILLED SULPHUR HANDLING)

SOLUTION FOR BULK MATERIALS, SHIP LOADERS, HOPPERS, BELT CONVEYORS, EXTRACTORS

Complete material handling system for FTS “BULK KREMI 1”. Design, full supply (MEC-ELE-AUT), commissioning and service. The Equipment shall be installed on a 14,000 dwt flat top pontoon crane (the “Vessel”). The Vessel is built under a shipbuilding contract to be entered into between the Purchaser and a shipyard (the “Builder”).

The transhipper is equipped with n° 02 cranes, n° 02 hoppers, n° 02 extractor, n° 01 longitudinal belt, n° 1 transversal belt, n° 01 longitudinal belt and a loader, designed for a capacity of 750 t/h of sulphur, but also able to transport coal and iron ore in different specific weights, using the inverters in the extractors, treating mainly 90% SULPHUR, 5% CARBON and 5% IRON ORE. The system allows the loading of OGV up to Panamax, so an 18m air draft with a draft at full load of 6.5m is planned. The shiploader can be traversed up to 50° to step over cranes between holds of ships with cranes and allows the loading using a retractable chute.

SOLUTION

Sammi in 2010 applied in the design and supply of an offshore vessel loading system. The scope of work includes a complete handling and shiploading system which is suitable to transport and load sulphur on vessels from Handy up to Panamax size. The plant will be installed on the Bulk Kremi trans-shipper and includes hoppers, belt conveyors and a shiploader, with a total span of 30 metres when fully extended. System specifications:

boom with slewing, shuttling and luffing functions;
material transfer from the feed chute at the pivot structure to the boom tip;
retractable loading chute, for efficient material distribution and to reduce dust emissions;
luffing angle up to 50° to pass over vessel’s mast or cranes to enable quick hold changes during loading;
design fully in accordance with directive Atex 94/9/EC regulations.

To date, engineering and construction phases have been completed, and all the equipment is ready for no load testing in Sammi’s premises. In 2011, the company was awarded of a contract for the design and supply of a turnkey coal handling for a rated capacity of 2,000tph of coal, to be installed in a new transhipper presently under construction. As for the project Bulk Java, the system will include double charging hoppers, belt conveyors and two continuous shiploaders both slewing and luffing-type. The launch of the new vessel is foreseen for midle of 2012. Looking at the project in greater detail, there will be operational tests carried out in which the shiploader will be completely assembled in the workshop together with its electrical and hydraulic power elements, to test that all slewing, luffing and shuttle functions operate as they should. The main advantage of carrying out these types of workshop tests is that they significantly reduce the time required in the shipyard for the assembly, commissioning and fine-tuning of the system. This further underscores Sammi’s commitment to meeting all the expectations of its customers. As well as the projects already in hand, the company is also undergoing feasibility studies for a range of further orders, with increased handling rates of up to 4,000tph, as well as for a variety of equipment to meet all bulk handling needs and requirements of its customers. Sammi’s technical solutions are all engineered to offer reliable, efficient and cost-effective operations.

SERVICES

Sammi was involved in the design, procurement, construction, surface tratment, transportation, erection, testing and start-up assistance for a trasportation, erection, testing and start-up assistance for a transportation system consisting of several machines intende for the reception, processing and transportation of coal/petcoke to power the cement mill.

BENEFITS

The system is designed to handle 750t/h of sulphur but is also able to transport coal and iron ore of various specific gravities, using inverters in the extractors. The ship loader is capable of rotating 270o about its own axis and vertically between 0o and 50o and is telescopic so its length can be extended by a further 30 metres. The fact that the ship loader can traverse allows the cranes to straddle the holds of crane ships, thus enabling them to be loaded. Special attention has been paid to environmental safety by reducing the formation of highly-explosive sulphur dust, by installing a retractable chute at the outlet of the ship loaders. The plant and its components are suitable for operation under hazardous conditions in compliance with the Atex Classification assigned to this type of application.

PROJECT FOCUS

DATA SHEET

The system has a transhipment capacity of 750t/h and it has been designed to handle sulphur as well as other main dry bulk materials and conceived to avoid any dust emissions during operations.
