In oil based systems, an insufficient amount of cooling medium or inefficient flow of oil through the heater can cause the heater to become fouled. Seawater coolers can often become fouled due to marine life present in the water or due to galvanic corrosion if the correct safety measures are not taken to prevent such occurrences.
Thermal treatment is a highly effective strategy for the control of zebra mussels (McMahon et al. 1995). Thermal treatment may include retrofitting a closed loop system to recirculate the heated water to the sea chest or the addition of a second sea chest system, allowing engine cooling water to be discharged through the idle sea chest.
Sea water air conditioning (SWAC), also known as ocean water cooling, is an alternative cooling system that uses the deep cold seawater as the chilling agent for a closed-loop fresh water distributed cooling system. It is one type of deep water source cooling. Once installed, SWAC systems typically operate at approximately 15% of the power ...
Fresh water aboard Queen Mary 2 is supplied by three Alfa Laval multiple effect plate (MEP) evaporators, each with a capacity of 630,000 litres (170,000 US gal) per day. [53] The plants' energy is supplied primarily by steam and cooling water from the ship's gas turbines and diesel engines, or if needed by steam from the ship's two oil-fired ...
Navigation and location of the ship by means of the analysis of the data provided by accelerometers and/or gyroscopes located on board, which integrate the accelerations experienced in complex electronic systems, that converted into velocities (in the 3 possible axes of displacement) and according to the observed courses, make it possible to ...
She had joined about 150 people for an outdoor summer-camp themed afternoon at the senior living facility, Touchmark South ... Slip-sliding away: Seniors glide into water nostalgia with summer's ...
Cold ironing permits emergency equipment, refrigeration, cooling, heating, lighting and other equipment to receive continuous electrical power while the ship loads or unloads its cargo. Shorepower is a general term to describe supply of electric power to ships, small craft, aircraft and road vehicles while stationary.
