Svanehøj Deepwell Cargo Handling Systems

For safely offloading a wide range of liquid cargoes, we offer the most flexible and environmentally sound solutions.

Our high quality deepwell cargo pump systems are powered by quiet, efficient electric drives that are fast and easy to install.

We specialise in competitively priced full cargo and ballast systems including drive systems, switchboards and accessories.

Around the world, we create custom-made turnkey solutions for any tanker, with full project management from start to safe on-time delivery and installation.


Because the needs of tankers and their cargoes are so diverse, Svanehøj delivers the widest range of tailored pump solutions, delivering savings through lower CAPEx before OPEX costs. 

We are unique in supplying both centralised pump room systems and systems distributed around the vessel. Together, they enable us to deliver an optimum solution for any and every vessel, from small coastal tankers to 320,000 dwt+ VLCCs. As the largest supplier of compact, energy-efficient electric pump systems, we can deliver efficiency savings of 11-17% compared with hydraulic alternatives, with a record of outstanding safety and reliability proven the world over.

Pre-docking inspection

Svanehøj offer the possibility of sending a service supervisor for a pre-docking inspection during a discharge operation. Our service supervisor will monitor the cargo deepwell and booster pumps for any abnormal vibration, noise, leakages from shaft sealing system etc. and carry out performance test before/during the discharge operation. Our supervisor will bring calibrated pressure gauges to ensure correct pressure readings and Class approved equipment for machine diagnostics (FFT) and data collection from pump(s) and electric motor(s).

Performance test

The performance test of cargo pumps is carried out in order to assess the wear and tear in the pump unit. We recommend this to be carried out approximately one month before the planned dry-docking date. The “performance test sheet” will give an indication of lack of performance in comparison with the original performance test carried out in our test bed when pumps were new and approved by classification society. Please note that the performance test carried out by operating the pump(s) either during discharge operation or during circulating cargo against closed valve for a short period. After the pre-docking inspection and performance test of pumps, we are able to issue a “Condition Assessment Report” where we as maker state our recommendations, which can then be presented to the Classification Society Surveyor.
