Subsea Trenching
Where the jetting sled is the optimum means of subsea trenching (generally clay, sand, silt, and some soft rocks), the Calder designed and built pump units offer the performance and reliability required by the application.
Our Experience
Our experience in the design and build of high pressure, high flow pump units is extensive. Not just for subsea trenching, but for a variety of well service and well intervention applications in both safe and hazardous areas. Calder mobile and fixed, high pressure multistage centrifugal pump units are designed and built primarily for the offshore energy sector. The sector’s requirements and standards are necessarily high and, as such, our years of experience in the design and build of these pump units has allowed us to accumulate a vast wealth of knowledge in this area.
Control
To accommodate the need to control trench depth and width, our pump units can be supplied with variable pressures and flow rates. Units can be designed for permanent installation on a vessel, or mounted in a crash frame or container for easy transportation between projects. All instrumentation and controls are designed in-house, giving us the flexibility to design the control philosophy around your specific application and area of operation.
