A Platform supply vessel (often abbreviated as PSV) is a ship specially designed to supply offshore oil and gas platforms. These ships range from 50 to 100 meters in length and accomplish a variety of tasks. The primary function for most of these vessels is logistic support and transportation of goods, tools, equipment and personnel to and from offshore oil platforms and other offshore structures.
A primary function of a platform supply vessel is to transport supplies to the oil platform and return other cargoes to shore. Cargo tanks for drilling mud, pulverized dry cement, diesel fuel, potable and non-potable water, and chemicals used in the drilling process comprise the bulk of the cargo spaces. Fuel, water, and chemicals are almost always required by oil platforms. Certain other chemicals must be returned to shore for proper recycling or disposal, however, crude oil product from the rig is usually not a supply vessel cargo.
Lion Bulk Handling is an partner for supplying complete integrated bulk material solutions. Bulk material handling systems are crucial for offshore support vessels (PSV or 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 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.
Space on these offshore support vessels is limited and requires customised designs. Every vessel has its own specification regarding the material handling system. Ruyter Offshore provides its customers with three different system designs and several options that can be built on board the vessel.
Offshore supply vessels are traditionally provided with a set of pressure tanks (P-tanks) as a bulk material handling system. Such a system uses dry bulk tanks to load, store and offload the dry bulk material. Alternative systems like the sender tank and the re-loader tank (vacuum pressure) systems are available as possible alternatives to dry bulk tanks. These systems contain more cargo volume within the same space than that occupied by the dry bulk tanks. Both designs are based on the cement carrier technology applied in the industry for almost fifty years. The first such systems were already designed, delivered and installed in 1985 and are still working today.
We will be delighted to assist you in choosing the right system for your offshore support vessel’s bulk material handling system.
