Dealing with self unloaders stalled lift belt; Conveyor belt construction & troubleshoot guide; Conveyor belt installation guide; Conveyor belt repair & maintenence guide; Preventing conveyor belt fire onboard self unloading bulk carriers; Cargo work safety precautions

During loaded passages in the winter, the motion of the vessel in heavier weather will tend to cause the cargo to further settle and compact. While loading the cargo, a judgement must be made on its expected flow-ability, and taking into account the expected conditions on passage, the relevant Management Office and Owners are to be notified of expected delays at the …

How to prevent conveyor belt fire during cargo operations onboard Self- unloading bulk carrier. ... This site is a quick reference to international shipping community with guidance and information on the loading and discharging of modern bulk carriers so as to remain within the limitations as specified by the classification society.

PURPOSE:To securely prevent biting of spilled cargoes between a roller and a belt, and to reduce generation of failures by arranging a cargo invasion preventing means to cover the contact starting part between a descending side belt and a conveyor return roller on the lower side of a vertical belt conveyor. CONSTITUTION:A vertical conveyor 5 is provided with a bulk cargo …

At the discharge port the vessel will most probably berth on a rising tide, and it may be crucial to discharge a quantity of cargo to lighten the vessel before low water to prevent grounding. This is especially true when discharging to a shore …

Dan Marshall, a process engineer at Martin Engineering, explores how conveyor components can mitigate the spillage, dust, and flow issues associated with material discharge and belt cleaning. Suggesting the "total discharge" of cargo from a conveyor belt in any bulk handling application is enough to make operators and maintenance staff ...

PMT deliver heavy-duty conveyors integrated with self-discharging system for efficient bulk cargo discharging. Conveyors systems are delivered in customized size with robust conveyor belts …

Some ships are fitted with cargo loading/ unloading equipment including cranes, grab buckets and wings with conveyor belts on deck (to pour the chips into cargo holds). When discharging, the ship's cranes are used together with a grab …

Such pieces of equipment might cause serious damage to conveyor belt systems and consequent delays, for which the ship will be held liable, should they be inadvertently discharged with the cargo. ... All these factors have a serious consequence on the methods of operation for the safe carriage of bulk cargoes. Discharging bulk cargo using grab ...

dust ­ iron ore is commonly loaded with conveyor belts, grabs, chutes and bucket belt unloaders, causing significant quantities of dust during both loading and discharging. However, enclosed conveyor belt systems generate less dust. The dust may damage ship's machinery as well as the health of personnel.

Her C-loop conveyor belt system lifts the ore from the longitudinal conveyors running below her cargo holds, and deposits it on the conveyor of the deck-mounted discharge boom. The 79-metre boom is positioned over the cargo …

In case of need, cargo can be stored onboard for some time, and certain, sophisticated Cement Motherships incorporate even a bagging plant, by which method bulk cement can be converted prior to discharge by conveyor belt for onward distribution. Bulk Cement is thus a perfectly feasible cargo for conventional bulk carriers, although it is ...

From the hoppers the cargo is fed onto longitudinal belt conveyors and transferred to a cross conveyor which discharges via a boom conveyor into the shore receiving facilities. Depending on the number of cranes and hoppers, a …

In Fujairah two conveyor belts (one 3.3 km and the other 4.8 km) connect the stockpile area with the two bulk loaders inside the port, resulting in a highly efficient vessel loading operation. While a closed conveyor belt of 4.1 km is installed in Dibba. Key features: Three bulk loaders with up to 4,000 mt/hr loading capacity
