Erna Offshore cargo supply vessel making its way towards the Aberdeen harbour and docks for supplies.


Cargo[edit] Deck cargo A primary function of a platform supply vessel is to transport supplies to the oil platform and return other cargoes to shore. Cargo tanks for drilling mud, pulverized cement, diesel fuel, potable and non-potable water, and chemicals used in the drilling process comprise the bulk of the cargo spaces. Fuel, water, and chemicals are almost always required by oil platforms. Certain other chemicals must be returned to shore for proper recycling or disposal, however, crude oil product from the rig is usually not a supply vessel cargo. Support Common and specialty tools are carried on the large decks of these vessels. Most carry a combination of deck cargoes and bulk cargo in tanks below deck. Many ships are constructed (or re-fitted) to accomplish a particular job. Some of these vessels are equipped with a firefighting capability and fire monitors for fighting platform fires. Some vessels are equipped with oil containment and recovery equipment to assist in the cleanup of a spill at sea. Other vessels are equipped with tools, chemicals and personnel to "work-over" existing oil wells for the purpose of increasing the wells' productionDaily operations[edit] Crews sign on to work and live aboard the ship an extended period of time (4 – 6 weeks). This is followed by similar period of time off, often depending on the ship owner / operator the number of weeks or months aboard, specially this period the Companies due to lack of Offshore projects could ask to remain on board from 1 to 3 months, and after this trip 1 month off. Work details on platform supply vessels, like many ships, are organized into shifts of up to 12 hours. Living aboard the ship, each crew member and worker will have at least 12 hour shift, lasting some portion of a 24-hour day. Supply vessels are provided with a "bridge" area for navigating and operating the ship, machinery spaces, living quarters, and galley and mess room. Some have built in work areas.
