The Marinsa charter fleet includes fast supply vessels, offshore supply vessels, crew boats and pilot boats. When Marinsa committed to fleet expansion of Offshore Supply Vessels with the addition of the Marinsa Amethyst and the Marinsa Turquoise, the ships underwent refit work to provide the capabilities needed for offshore drilling.
Fresh water generation on board is needed to provide water for drilling mud mixing for cementing and for all the potable requirement of the crew who can be offshore for weeks at a time. Fresh water demand is expected to fluctuate widely depending on the type of mission scope, but regardless Marinsa need a reliable source of fresh water supply. And the equipment needed to be supplied quickly to match an aggressive shipyard schedule.
Ampac USA supplied Marinsa two 40,000 GPD watermakers, one installed on each of the new OSV’s. To simplify the installation, each watermaker was supplied as three modules. The main module included the control center, the instruments, and the prefiltration. The RO membrane were racked in a separate module. And the high pressure pumps were also mounted on a separate skid.
A critical component of the watermaker is the 10 inch color touchscreen control panel allowing fully automated operation. Using a mimic display, the operator is provided full monitoring of the pressures, flowrates, water quality and temperature.
Components and accessories can be brought on or off line by simply touching icons on the screen. Setpoints and safety alarm sequences can be managed from the screen. The controller is driven by a powerful PLC that will log operating data and log fault conditions. The operating data can be monitored remotely through an ethernet connection, and historical data can also be downloaded onto a memory stick for record keeping.
