We maintain equipment that provides hotel services for the crew.
Air Conditioners - We have three 130 ton chill plants on board the ship. We keep them and the related pumps and air handlers in working order.
Refrigerators - We have two 3.2 ton refrigeration plants on board that feed refrigerant to three refrigerated spaces. One chill box, one chill/freeze box, and on freeze box. As the name denotes the chill/freeze box can be converted to be used as a chill box or a freeze box.
Ventilation - The ship uses numerous fans to both provide fresh air and get rid of used air through out the hull. Most of the fans have filters and coolers associated with them that we maintain.
Laundry equipment - We have two laundry rooms each having three washers and driers that we maintain. As you can imagine these are high on the priority list when they break.
Sewage equipment - We have two grey water holding tanks, three grey water lift stations, and one VCHT holding tank. All have related pumps, valves, and sensors that we maintain.
Galley equipment - Even though the cooks use it to cook, we maintain it. Mixers, steam kettles, stores elevators, etc are all are responsibilities.
We provide clean fuel for the boat, small boats, and helicopter.
Provide the Fuel Oil Water King (FOWK) - The FOWK is responsible to keep the liquid loading of the ship right. He does this by transferring fuel and adding or removing ballast. He also predicts how much fuel we will need at the next fuel stop. The Bertholf Holds 219,000 Gallons of fuel.
Maintain fuel tanks - We inspect tanks as needed according to the preventative maintenance schedule.
Fill fuel tanks - We are the ones that take on fuel while in port.
Filter the fuel - We have two fuel oil purifiers on board that clean the fuel as it is transferred from the storage tanks to our 6 service tanks.
Maintain fuel transfer equipment - We have fuel transfer pumps and fuel oil purifiers that need to be cleaned and maintained periodically.
Maintain the JP-5 fuel system - We maintain the helicopter JP-5 fuel system. We do this by recalculating the tanks and testing all the equipment and fuel. There are very strict regulations concerning the fuel and how it is handled. Because of this a aviation team inspects us every year to make sure we are doing it correctly.
Maintain small boats.
We have three small boats on board. One SRP, one SPC, and one OTH on the boat. We maintain the propulsion and hull on each one.
Maintain the davit, and gantry for the small boats - To get the boats off the cutter we have on davit and a two place gantry. Both units require a lot of attention.
Provide small boat engineer - Though we are not the sole providers of boat engineers, anyone can qualify for it, we are the shop that is required to ensure there are enough small boat engineers to run the boats as needed.
Maintain the misc. equipment on the boat.
Maintain mooring equipment - We have warping capstans on every weather deck where lines are handled by the deck department. They assist the line handlers by pulling on the lines.
Maintain anchoring equipment - We have two anchor's on board with two hydraulic windlasses.
Maintain various compartments on the boat - As the Aux Dept, we have more spaces then any other department. Mostly because our equipment is in those spaces so we maintain the space as well as the equipment.
Maintain bow propulsion unit - We have tunnel thruster in the bow of the ship to help us in mooring and getting underway evolutions.
Maintain the steering gear - We have two independent steering gears that double as roll stabilizers.
How we fit in the big picture of the Coast Guard.
We maintain equipment on the Bertholf that allows the crew to complete CG missions (SAR, law enforcement, pollution response and public relations). The end product of our work is shown in the amount of days we are underway and missions completed.
