摘要:
A method and a draining adapter are provided for draining fluids, especially lubricant oils, from an engine or machine like a combustion engine and especially from a boat drive or another engine which is not accessible from underneath in order to open an outlet and let the fluid flow out. Furthermore, an accordingly adapted engine or machine is disclosed for applying the method and the draining adapter

An electrolytic sterilizing apparatus comprises an electrolytic module (10) including an inlet port (11-1) disposed at one end thereof for allowing ballast water (40) to be introduced therethrough, an outlet port (11-2) disposed at the other end thereof for allowing the ballast water (40) to be discharged therethrough, a baffle unit (20) mounted at the inlet port (11-1) side for generating eddy flow, a sensor (30) mounted at the outlet port (11-2) side for measuring residual chlorine concentration, and a chamber (11) disposed between the baffle unit (20) and the sensor (30), the chamber (11) having electrode sets (12-1) mounted therein, each of the electrode sets (12-1) including a pair of electrodes (12), a power supply unit (50) for supplying power to the electrolytic module (10), and a connecting unit (60) including a pump (61) for introducing and discharging the ballast water (40), a pipe (62) connected to the pump (61), and a valve (63).
摘要:
Disclosed is a personal watercraft capable of separating and eliminating water contained in fuel without inspecting whether or not the water is present in a fuel tank. The personal watercraft comprises a water separator 21 in a fuel supply passage from a fuel tank 14 for reserving fuel supplied to an internal combustion engine 4 to an air-fuel mixture generating means 17 for mixing fuel with air to generate air-fuel mixture.
摘要:
Upon loading of oil cargo the ullage space of a tank of an oil tanker is sealed substantially gas tight with the gaseous contents of the ullage space both (i) initially inerted so as to be incapable of supporting combustion of any oil within the tank, and (ii) at an initial pressure less than atmosphere. The tank is preferably continued closed, preferably optionally with closed loop recirculation for purposes of gas mixing, for the entire voyage of the tanker save that (1) ullage space gas pressure uncommonly exceeds limits because of any of (i) leakage of atmospheric gases into the tank, and/or (ii) outgassing of gases within the oil contents of the tank, (iii) evaporation of the oil or portions thereof, and/or (iv) expansion of the ullage space gases upon thermal heating, and/or (2) free oxygen within the ullage space gases exceeds limits because of any leakage of atmospheric gases into the tank, at which time the tank is re-inerted, preferably with flue gases, or again de-pressurized, as and when required. Normally ullage space gas pressure remains, nonetheless to potentially becoming more positive, suitably negative throughout the entire voyage of the tanker, continuously preventing that hydrostatic pressure within the tank should equalize with a surrounding ocean upon any occasion of incipient rupture of the tank below the water line and thus continuously precluding at least some outflow of oil as would otherwise occur upon the occasion of the rupture. Normally free oxygen within the ullage space gases remains, nonetheless to potentially increasing, suitably low throughout the entire voyage of the tanker so as to prevent that combustion should occur.
摘要:
A waste disposal system for a boat equipped with a head and a waste-holding tank for receiving sewage therefrom. A dual deck fitting and associated equipment permits conventional dockside pumpout of the holding tank and also permits overboard dump of the contents of the tank. The dual deck fitting is provided with a pair of plugs, one of which embodies a pivotable handle which facilitates threading and unthreading of the plug in the deck fitting and also a lug which engages a slot in the other plug to facilitate threading and unthreading of the latter plug in the deck fitting.
摘要:
A system for collecting waste discharge by gravity into float supported pipes. The pipes terminate into a submerged sewage holding and pumping station. From there it is pumped into existing sanitary sewer lines on shore.
摘要:
A water permeable container charged with an antimicrobiological compound, e.g. dichlorophen, which when inserted into water, e.g. ships bilge water, will cause the compound to be dispersed into the water as a dispersion for cleansing the water of microbiological organisms, the compound being noncorrosive to metals, acting over a temperature range found in watercraft and having a low toxicity to humans.
摘要:
A vessel-based system and method for disposing of wastewater including bilge water from a bilge of the vessel. The system including a treatment unit for receiving and treating the wastewater to produce a substantially oil-free treated water and, an evaporator for receiving the treated water from the treatment unit. In an embodiment, the evaporator having an evaporation element for transferring heat to the treated water to evaporate the treated water.
摘要:
A ship comprises a bilge water sump collecting bilge water and contaminants. A first contaminant separation device is provided comprising a conveyor arrangement with an endless belt comprising adsorbing/absorbing material. The conveyor arrangement has a first portion submergible into the bilge water and contaminants in the bilge water sump, and a second portion being spaced from the first portion and provided with means for releasing adsorbed/absorbed contaminants from the conveyor belt and means for collecting the contaminants released. The conveyor arrangement is further provided with means for driving the endless belt along a moving path defined by guiding means.
