CMSIL delivers custom-built diving support vessels,  as well as the pre-designed modular CMS Supporter® class series with saturation diving equipment.

Diving support vessels operate as a floating dive base. Onboard, divers remain under high pressures in saturation dive chambers. The divers are transported to the work site by means of a diving bell, where they are involved in maintenance, repair and inspection activities.

CMSIL diving support vessels are designed to support: professional diving projects; global installation, maintenance and repair work; and other tasks such as subsea and offshore construction.
