Fabrication of Anchor Anchors are fabricated from a number of materials; the earliest ones being made from large stone blocks, sacks of sand, wooden logs or from mesh baskets filled with an assortment of stones. Once the industrial revolution came along, blast furnaces produced the pig- iron from which cast iron anchors were made. Following […]
Operation of Anchors Using a Capstan or Windlass Anchor chains are connected to a windlass that can either be of vertical or horizontal design. A vertical windlass is known as a capstan, and we shall describe the operation of the anchor and its components using a capstan. The capstan has a drive wheel called a […]
Oil in The Refrigeration System in Marine Indication oil in the refrigeration system : Temperature is not dropping in the cold rooms as normal, due to fact that oil act as insulation in the evaporator. It may cause excessive frost on the suction line. Refrigerant compressor runs for the extended period of time. Lubricating oil […]
Air in The Refrigeration System Indication air in the refrigeration system : This may cause the refrigeration compressor to overheat, with a high discharge pressure and normal condensing temperature. There are possibilities of small air bubbles in the liquid sight glass of the condenser. Condensing pressure of the refrigerant in the condenser may be high. […]
Moisture in The Refrigeration System This normally comes with the ingress of air in the system. Moisture may freeze at the expansion valve, giving some of the indication of under charging. It will contribute to the corrosion in the system. It may cause lubrication problems and breakdown of the lubricating oil in the refrigerant compressor. […]
Overcharge of Refrigeration System Indication Overcharge of Refrigeration System : The liquid level in the condenser is too high (high condenser gauge reading). This will reduce the available condensing surface, with corresponding increase in the saturation temperature and pressure. High pressure switch of the refrigerant compressor activates and stops the compressor. The suction and the […]
Marine Refrigeration System A marine refrigeration system is a key element onboard any vessel. Food and drinks, cargo and garbage need to be kept in optimal conditions at all times. Well-maintained food and drinks are essential for passengers’ and crew’s health. And many cargo ships need to be equipped with high quality marine refrigeration and air […]
Regulations Watertight Bulkheads in Ships The safety of a ship in damaged condition is majorly dependent on the strength and integrity of its watertight bulkheads. There are a lot of factors that go into deciding the position of watertight bulkheads in a ship, and designing them structurally. Watertight bulkheads are vertically designed watertight divisions/walls within the ship’s […]
Marine Refrigeration Systems The objective of any refrigeration system is to collect heat from a low temperature area and move it to a high temperature area. Refrigerant is a substance that acts as a cooling agent by absorbing and giving off heat. Usually there are two types of refrigeration systems commonly encountered : namely the […]
Reducing Oil Level in Compressor If the oil level in the compressor crank case of the refrigeration system is reducing within short intervals, this indicates leakage or increase in consumption of lube oil due to following reasons : Reasons Solutions Nozzle or filter clogged. Ensure that the nozzle in oil return line or filter in […]
