Offshore support vessels are often equipped with tank capacity for recovered oil. Systems meeting NOFO standards will have a circulating/heating system for these tanks, as oil recovered from spills will often need heating before it can be transferred to a facility ashore or to a tank barge. Tanks will have an external circulating pump, and traditionally the heating method has been to generate steam which is injected into the tank contents, using fuel in doing so.
Pyro can provide ORO tank heating which uses waste heat, thus saving fuel, the energy being transferred by the thermal fluid system.
A small thermal fluid heat exchanger is fitted in each tank close to the circulating pump suction, effectively heating the tank contents. Fortunately, oil spills are not an everyday occurence, so the recovered oil tanks may be empty or used for other purposes for much of the time, with no need for heating.
The Pyro heat exchangers are arranged with a flange to the tank. When required they can be quickly fitted, replacing a blank flange in the side of the tank. When not in use they can be stored out of harm’s way.
