Hydrojetting and ibc/obc

Aside from Heat Exchanger Servicing, we also specialize in the Thermal Design
of Heat Exchangers and Thermal Equipment.


Dolphin has the most advanced, high, and ultra-high, pressure water jetting equipment as well as the accompanying safety gear available. Our fleet of pumps ranges from 3,000 to 50,000 psi, and our facility is laid out in a way that ensures reliability and optimum performance of all equipment. We can also provide a variety of purpose-built offshore equipment to fulfill the criteria and requirements of the offshore oil and gas industry.

In addition to our fleet of hydrojetting pumps, we employ high capacity Rigid-Lance Inside Bundle Cleaning (IBC) Machines and Outside Bundle Cleaning Machines.


The IBC is designed to handle a large quantity of Heat Exchanger Bundles during Turnaround. The IBC cabin is on top, giving the operator the best view of the tube sheet for maximum efficiency. The IBC cleans 5 Tubes, at one time, with an average speed of 500-750 Tubes per hour. It is very comfortable for the operator and maximum safety and very reliable and powerful machine for all types of Heat Exchangers.

The OBC is a productive shellside cleaner for use in the cleaning bay during turnarounds. The operator is very comfortable in a separate larger cabin completely protected from the high pressure water and contamination. This cabin allows for a clear view of the bundle and gives the operator full control of the nozzle bar which can be manipulated in three directions; “horizontal, vertical and in/out”.
