J. Lauritzen

Lauritzen have increased the flexibility of its fleet of bulkers with inventions such as grabs for handling cement. This allows the company to carry cement to destinations that lack the infrastructure to accom­modate specialist cement carriers or large ships.

The benefits are higher utilization for the fleet as well as cost savings for the client from the cargo arriving closer to its final destination, which also reduces transhipments and environmental impact.

J. Lauritzen was founded in 1884 and remains whol­ly-owned by the Lauritzen Foundation. J. Lauritzen’s business activities encompass: Lauritzen Bulkers, Lauritzen Kosan, Lauritzen Offshore and Lauritzen Tankers. The company is headquartered in Denmark and has activities worldwide with offices in, China and Japan, Philippines, Singapore, Spain and USA.

J. Lauritzen has about 1,300 employees worldwide and the company controls about 165 vessels.

Developing of dust-eliminating grabs

Lauritzen Bulkers is a significant provider of tonnage to the cement trade. Besides cement and clinker, Lauritzen uses its fleet to transport a variety of other cargoes requiring special transport arrangement, incl. minerals, agricultural products, wood logs or wood pellets.

Cement and clinker is a challenging cargo to load, transport and discharge. A substantial part of the cement business takes place in ports with limited infrastructure whereby both the environment and the physical space available makes it a challenging task to load or to discharge. The greatest challenge is related to the generation of dust, presenting danger to the crew, ship’s installations, port infrastructure and surroundings, and the cargoes of other ships. To address this, Lauritzen has developed special dust-eliminating grabs for cargo handling.

Loading ships to their full potential

The use of grabs also allows the crew to load the ship to its maximum capacity without jeopardizing stability or inducing dangerous structural stresses. Cement has a low angle of repose, which means that it has an inherent tendency to form a cone when it is loaded using conveyors. This gives rise to two problems. A cone can shift on voyage, creating stability problems. Moreover, coning is an inefficient way of loading cargo because it leaves part of the holds empty. The use of grabs eliminates the risk of coning because the operator of the grabs distributes the cargo evenly in the hold.

Trained crew reduces risks

Trained crew on-board Lauritzen Bulkers ships increases the efficiency and reduces the risk of incorrect loading, accidents and cargo spillage. It also increases efficiency in preparing and cleaning the hold and reduces the risk of improper mainte­nance of the grabs. Furthermore, the crew is able to leverage its experience to either repair the grabs or remedy the costs in terms of time, money and the en­vironmental damage by taking action immediately. The presence of an experienced crew helps ensure an efficient flow of operations ashore as well.

Better utilization of port infrastructure

The use of grabs means maximum use can be made of the port capacity available. The infrastructure avail­able in many ports may pose limitations for loading and discharging cement. However, making use of the port capacity available is particularly important in the case of cement and cement clinker because they are low value products. Transport costs can add up to a large part of the final value of the cargo.

Better utilization of port infrastructure also means more cargo shipped with fewer vessels entering the port reducing waiting times for others.
