DEEPWELL CARGO HANDLING SYSTEMS FOR PRODUCT/CHEMICAL TANKERS

Wärtsilä Svanehøj deepwell cargo pump systems are designed to handle various liquid cargos, while meeting IMO and all major classification society requirements. Our high quality deepwell cargo pumps and necessary components ensure safe offloading of product and chemical, and can be supplied in either cargo or oil lubricated. Wärtsilä Svanehøj, located in Aalborg, Denmark, is dedicated to manufacturingdeepwell pumps, focusing on developing outstanding electric driven pumps for the marine industry. All of Wärtsilä’s combined expertise and know-how is integrated in our pump systems which is why we are proud to say that our CKL and DL pumps are more than a deepwell pump solution – it is a promise of a highly reliable system,

minimized new-building and project risks, operational flexibility, economical and efficient lifetime operation and many other benefits, all wrapped up in unique and innovative designs. As a supplier of complete cargo offloading pump systems, our scope of supply includes: cargo pumps, slop pumps, ballast pumps, tank washing pumps, portable pumps, explosion proof electrical motors, frequency converter, electrical switchboard, remote cargo control systems, electrical filter solutions (if necessary). In addition to a high level project management team – from the start of the project to delivery of the solution – ensuring a safe and reliable system installation.

PUMPING EFFICIENCY INTO CARGO OPERATIONSFor safely offloading a wide range of liquid cargoes, Wärtsilä Svanehøj offer the most flexible and environmentally sound solutions available - high quality deepwell cargo pump systems powered by quiet, efficient electric drives. Our engineers can supply a custom-made turnkey solution for any tanker - high grade engineering for a high performance up-to-date system, with full project management from start to safe on-time delivery and installation. We offer an outstanding service to shipyards around the world, delivering full systems, competitively priced and comprehensively supported.

ELECTRIC CARGO HANDLING SYSTEM FOR HIGH ENERGY EFFICIENCY

FREQUENCY CONVERTERS FOR OPTIMUM PRESSURE AND FLOW

CO2 emissions has had more and more

global awareness in recent years, plus fuel saving and low lifetime operational costs are essential for ship owners when choosing a reliable cargo handling system. With a Wärtsilä Svanehøj deepwell cargo pump system, ship owners will ultimately get the most flexible and environmentally sound cargo handling solution present today. Wärtsilä Svanehøj electrically driven deepwell cargo pump system supports IMO´s Energy Efficiency Design Index (EEDI) and has significantly higher system efficiency than its hydraulic driven counterparts. It is also easy to install, low maintenance and offers reduced discharging noise levels. Wärtsilä has delivered electrically driven, variable speed regulated cargo systems to over 250 vessels with various cargo densities and viscosities to achieve optimal performance.

All Wärtsilä Svanehøj deepwell pumps are designed for operation with frequency converter (or other means of variable speed regulation) making the pumps particularly suitable for handling different types of cargoes within a wide range of specific gravity and viscosity. Frequency converters are delivered in a converter switchboard, fully wired and ready to be placed in the switchboard room. The converter switchboard is made with interface for remote control panel and connectivity to the Ship’s Control System (SCS). By means of the frequency converter it is possible to adjust the speed for optimum pressure and flow, resulting in considerable physical and economic energy savings, which

contribute to increasing ship owner’s return on investment. A matrix frequency converter configuration are recommended to minimize the number of frequency converters needed, and at the same time provide redundancy in the cargo frequency converter switchboard.

DEEPWELL PUMP TYPES

ADDITIONAL COMPONENTS

Wärtsilä offer two types of cargo pumps for Chemical and Product tanker operation. Both pump types have been developed through extensive research and experience within our in-house facility in Aalborg, Denmark and tested within our own 33m testing tower. The DL pumps covers capacity ranges from 30 m3/h to 500 m3/h and the CKL pump range covers a higher range of capacity from 500 m3/h, up to 1800 m3/h. The Wärtsilä Svanehøj cargo pump consists of four major sections:

ELECTRIC MOTORElectric motor in approved explosion-proof and weatherproof execution for open deck installation. Suitable for speed regulation with frequency converters.

DECK ARRANGEMENTDeck arrangement with motor stool, integrated lubricating oil header tank, upper drive shaft bearing, purging and stripping connections. As standard the discharge flange is made according to EN 1092, PN16. At request other standards, such as ANSI and JIS, are available.

PIPESTACKThe pipestack consists of a cargo pipe and an oil-filled drive shaft column with slide bearings. The oil-lubricated bearings are held in position by flexible O-rings. The transmission shaft is made of carbon steel alloy. For lengths above 8m an intermediate support to bulkhead is required.

PUMP HEADPump head with double mechanical shaft seal, stainless steel shaft and ball bearing arrangement. The shaft seal arrangement consists of a primary seal against the cargo and a secondary seal against the lubricating oil in the drive shaft column. The cofferdam between the two mechanical shaft seals has pipe connections to deck for purging. The casing wear rings are easily accessible.

HYDRAULICALLY DRIVEN PORTABLE PUMPThe hydraulically driven portable pump can be connected either to the ship’s hydraulic system or to a hydraulic power pack unit via a ring line. Easy to connect by quick couplings and maneuvering of pump by a flow regulating valve makes the handling of the portable pump swift and trouble-free.

AUTOMATIC STRIPPING SYSTEMOur automatic stripping system is an excellent way to drain off the residual liquid in oil product/chemical tankers. The system distinguishes itself by easy operation and maximum reliability due to its simple construction.

BALLAST PUMPSThe Wärtsilä Svanehøj deepwell ballast pump type C2G-SUB is a single suction

LOWER COST AT SHIP YARD & BEYONDElectric systems promise lower total installed costs at the shipyard and lower running costs than hydraulic systems.

ENHANCED HSEElectric pumps offer lower CO

2 emissions/

environmental impact than hydraulic pump solutions; low noise electric pumps preferred by crew.

DELIVERY EXCELLENCEHighest standards of on-time delivery consistency.

WHOLE LIFE SUPPORTWorld-leading technical support throughout the life of the system, through Wärtsilä’s world-wide network.

MULTI-CARGO CAPABILITYDesigned for use with Frequency Converters – suitable for cargoes within a wide range of specific gravity and viscosity, as well as energy savings.

PROVEN RELIABILITYProduct references proven over 45 years, building Svanehøj’s global reputation for excellence.

HIGH EFFICIENCYHigh performance deck mounted electric pumps can operate more efficiently than comparable hydraulic systems.

AN UNRIVALLED MIX OF ADVANTAGES

in-line centrifugal pump, designed for a reliable and efficient operation and consists of a submerged pump head, transmission to deck and electric motor. The pump is designed for direct on-line (DOL) starting and can also be operated with a frequency converter or other means of variable speed regulation.
