Offshore Vessels

Bulk material handling systems are crucial for offshore support vessels (OSV) to perform their supply function. The main task of the bulk material handling system is to receive, store and discharge dry material. In conventional systems, the storage and discharge of dry material is performed by pressure bulk tanks.

Ruyter Offshore (a Lion Bulk Handling brand) designs and engineers dry bulk material loading and unloading systems for several kinds of offshore support vessels such as PSVs, OSVs and AHTS vessels. Offshore support vessels are equipped with pneumatic dry material handling systems and can be complemented with dust recovery and control units which meet the highest international requirements. Some offshore support vessels are equipped with liquid mud mixing equipment, which can be integrated with the dry material handling system.

A Ruyter Offshore cargo control system (CCS) can also be provided, integrated in the vessel management system (VMS, VAS, ECR or IAS) or as a standalone unit.

The dry bulk materials – cement, barite, and bentonite – used in the drilling process are transported from shore-based stations by offshore support vessels and are unloaded to offshore drilling platforms.

Pressure Tank System

The pressure tank or P-tank system is a conventional system used on offshore rigs. The system deploys several pressure tanks to receive, store and discharge cement and drilling powders on the rig. 

Sender Tank System

The sender tank system is a bulk handling system on offshore rigs. It uses several atmospheric, hull-integrated hoppers to transport cement and drilling powders from shore to offshore destinations.

Re-Loader Tank System

The re-loader or double re-loader tank systems are used to store dry bulk material onboard offshore rigs. The system uses several atmospheric hoppers to store cement and uses a vacuum to remove material from the hoppers.
