Screw (FK) Pumps Technology
| Apr302019
The Carlsen Screw Pump System is the world’s most commonly used pneumatic conveying system on board of Self-Discharging Cement Carriers (SDCC). An FK pump (Fuller-Kinyon Pump) or also named Material Handling Pump or Screw Pump, is installed in a tunnel underneath the fluidized floor in the cargo holds. Cement or other powdered material is then conveyed through the discharge pipelines to the onshore storage facility. More than 15.000 pumps are supplied already, the Screw Pump System is a proven solution for unloading SDCC’s. The screw pumps can reach capacities up to 700 tph and conveying distances up to 1500 meters. Introduced in 1926, the Fuller-Kinyon (FK) pump technology provides lower power consumption, lower maintenance needs, and increased efficiency, flexibility, and

| Mar122019
The trade of cement and similar dry materials results in new ship capacities and an even bigger demand for ship conversions of conventional bulk carriers into specialized self-discharging cement carriers. Self-Discharging cement carriers do not require any shore based ship unloading equipment and discharge into a totally enclosed material handling system, using a fluidization floor system in the cargo holds for cement unloading. Up to now, the world fleet comprises about 300 units between 1,000 dwt and 60,000 dwt for seaborne cement transportation. Additionally, about 200 units smaller lake and/or river barges and ships of <1,000 dwt. When do you consider a ship conversion or when do you decide to build a new cement carrier? This blogpost will look at

Each owner of a bulk handling system understands the importance of performing regular maintenance versus trouble free operating and income. Besides this maintenance, the knowledge of system operating crew is of high influence on the equipment’s performance and process. An explanation of this crew skills influence has been addressed in our earlier blog: PNEUMATIC SHIP UNLOADER: Operator Skills vs Unloader Capacity Quite some equipment owners have the feeling that only good maintenance is the ticket to trouble free operation with the corresponding saving/earnings in operational costs. In this blog, we are going to address another factors for reducing operational costs for gaining even more production rates with is frequently yet unknown under equipment owners. Most bulk handling systems are equipped with valves,

| Oct152018
As its name implies, a feasibility study is an analysis of the viability of an idea. The feasibility study focuses on helping answer the essential question of “should we proceed with this project idea?” All activities of the study are directed toward helping answer this question. Feasibility studies can be used in many ways but focus primarily on proposed businesses and innovative technology. Charters, ship owners, shipyards and other companies with ideas conduct feasibility studies to determine viability before proceeding with project development. Realizing early on that an idea will not work saves time and money later. For more than 50 years Lion Bulk Handling, together with our product brands Carlsen, Kintec, Ruyter Offshore & Bulk Academy, has been providing

Lion Bulk Handling is focusing on complete bulk handling logistic solutions to create an optimal bulk material flow. Multiple applications are possible for creating an efficient logistic chain of bulk handling systems for loading, unloading and storing of bulk materials, such as cement, barite, bentonite, fly-ash, etc. Because multiple applications are possible for creating a bulk handling logistic chain to create the movement of bulk materials from A to B, the decision making process is complex. We at Lion Bulk Handling are used to advice and guide our clients through this decision making process. Because of our 50 years of design and engineering experience in bulk material handling systems for application in the cement, marine and offshore industries, we

Cement bulk handling equipment for vessels/barges comes many varies concepts, whereas basically the separation is between Closed Hatch vessels/barges over Open Top vessel/barges, like for example; Open top vessels/barges; Pneumatic Ship Unloader Pneumatic Ship Unloader (pneumatic system, based on using a vacuum for collecting the cargo trough a pipe which is mounted onto a manipulator arm moving in the vessel holds and temporarily stores it into Re-loader Tanks and use compression in the following cycle to convey it in badges towards the storage facility on-shore) Mechanical Ship Unloader Mechanical Ship Unloader (mechanical system, based on using an upwards rotating screw for collecting the cargo trough a pipe which is mounted onto a manipulator arm moving in the vessel holds and

The offshore oil and gas industry is going through difficult times. With the oil price low and more and more rigs being stacked, there is less demand for the services of platform supply vessels in particular. AHTS vessels are at least picking up short-term work in moving rigs to scrapyards and layup locations, though more than this is required to keep fleets busy. Many vessel owners are now looking at options for utilizing their tonnage outside of the traditional OSV sector. Owners and operators of offshore support vessels (such as AHTS, PSV & OSV) and offshore (drilling) rigs (such as Jack-up & semi-submersibles) are under no illusions about the year ahead. 2017 is expected to be one of the toughest

| Apr102018
Besides regular maintenance, there is a direct link between the skills of the operators in relation to the ship unloader capacity. In other words: when the operators are not skilled, it will influence the unloaders performance. Basically there are 2 different types of pneumatic ship unloading systems: fully-automatic or semi-automatic. Fully-automatic Unloader: This type of equipment is capable of unloading the ship fully-automatic by means of a PLC/HMI, valves, instrumentation and a logic on the needed valve sequences allowing to collect and convey the dry material from A to B. This equipment is better known as shore Stationary or Dock mounted Pneumatic Ship Unloaders whereas the ship itself is equipped with the needed floor & piping onboard. Allowing the cargo

Climate protection as the only argument does not seem sufficient for the partly highly expensive investment in energy efficient technologies. But due to increasing energy costs, energy efficient equipment gets more and more attractive.

In this live case study, we have visited a customer in South Europe who has acquired a Pneumatic Shipunloader more than 10 years ago and requested a tuning and tweaking visit by one of our field engineers. During its lifetime operation the equipment undergone normal wear and tear and lost performance in the run. The goal was to allocate the potentials on gaining back this performance, which were able to find by following these steps resulting in an increase of 11%! This visit has been executed in multiple stages; General walkaround on the unloader making sure that there are no visual leakages like oil and water, no abnormal noises/vibrations, instrumentation/electrical cables still in place Readout and Clear the PLC internal
