- sea box coolers such as those used on ships, offshore platforms, etc.
- components such as filters, fittings, pipes, heat exchangers, pumps, sea box coolers inter alia, which are in contact with sea water sporadically or continuously in open sea boxes and sea water systems, for the targeted local and short-term overheating of the enclosed sea water by using the waste heat contained in the engine cooling water according to claim 1.
- DE PN 31 23 682 AI describes a vegetation-proof metallic material with an alpha single-phase structure, consisting of an alloy with 5-30% by weight - Mn, at least one element such as Sn with up to 5% by weight.
- the disadvantage is that this is not a standard steel in shipbuilding and therefore leads to considerable price increases for the ship.
- anti-fouling or antifouling protective layers are formed, for example, by plasma polymerization in accordance with DE PN 3522 817, or in accordance with DE PN 2756 495, a silicone rubber is applied to metallic surfaces. Contamination of the lake water with chemical substances is considered a disadvantage here.
- US Pat. No. 3,309,167 describes a method for preventing growth, in which the growth-preventing effect of a temperature increase which is to be repeated regularly is used.
- the growth-preventing effect of a temperature increase which is to be repeated regularly is used.
- the u.a. Invention which aims to heat the enclosed water in temporarily closed circuits by engine heat, is heated in the US patent mentioned, the outwardly adjacent surface to be protected directly by an electrically operated heating element, which requires an additional expenditure of energy.
- US Pat. No. 3,650,677 relates to a method for sea boxes for temporarily overlaying the inner walls by adding vegetable oils and fats, especially during the winter break, in order to prevent destruction caused by ice formation and to prevent corrosion.
- the higher temperatures mentioned in the patent refer to the heating of the oils and fats for spraying in the sea tank or to their removal at the end of the winter break. There is no discernible reference to the prevention of fouling. Vegetation usually does not start in winter when there is a risk of ice formation, but in late spring at temperatures above 10 ° C.
- the stated invention is based on the object of an effective and environmentally friendly method and a device for preventing and preventing fouling on surfaces of pipelines, filters, heat exchangers, fittings, pumps, sea case coolers which come into contact with sea water and which are sporadically or constantly in contact with sea boxes Seawater is to be developed, which is easy to use and install at low cost, is easy to maintain and operate, has low operating costs and enables vegetation protection without the use of toxins.
- Sea case coolers for engine cooling water are coated with an antifouling paint, which, however, only offers protection against fouling for a short time.
- the so-called low-temperature sea chest coolers with an engine cooling water inlet temperature of approx. 45 ° C offer the larvae of barnacles, mussels and other ideal growth conditions, so that the coolers are already behind their cooling capacity can be extremely limited due to growth in a short time and, for safety reasons, be designed with an area reserve> 30%.
- the advantages of the invention are that by preventing growth on the sea case cooler, this can transfer larger cooling capacities with the same size by reducing the cooling surface, or build sea case coolers with comparable performance by approx. 20% smaller and thus be placed more easily in the often very small sea boxes can.
- the minimized size and the possible use of normal steel for the tube bundle ensure a significant cost reduction for the sea case cooler itself. This means that there may be no need for reserve coolers.
- the energy required to heat up the enclosed sea water is applied by the high-temperature cooling water of the main engine or the diesel generator cooling water.
- the complete sea chest with all internals can be preserved with the same coating system, so that the complex coating of the CuNilO Fe tube bundle and the associated problems of electrolytic corrosion after damage to the coating of the tube bundle are eliminated.

- Fig. 2 Sea case with closed outlet slots
- Fig. 3 Sea chest blind for closing the inlet slots
- Fig. 4 like Fig. 1, combination cooler, low-temperature sea case cooler with integrated high-temperature sea case cooler
- Fig. 5 Scheme of a high temperature and low temperature circuit with an additional external heat exchanger
- Fig. 6 Rollable elastic plate for closing the inlet and outlet slots
- Fig. 7 Circuit structure of the sea boxes in the mutual sea and cleaning operation
- the high-temperature cooling water of the main engine 13 or alternatively the cylinder cooling water of the diesel generators which is switched to the low-temperature cooling water circuit with the sea box cooler 2 by means of changeover fittings, is used.
- Fig.l shows the basic structure of a sea case 1 with low-temperature sea case cooler 2, a sea case blind 4 with a blind box 12 for blocking the outlet slots 3.
- the inlet slots 8 are blocked analogously (Sea operation) the low-temperature engine cooling water circulates at approx. 45 ° C through the low-temperature sea case cooler 2 and the sea water flows at max. 32 ° C through the inlet slots 8 into the sea box 1.
- This sea water cools the engine cooling water to a minimum of 36 ° C via the low-temperature sea case cooler 2 and leaves the sea case 1 via the outlet slots 3.
- the larvae of the growth organisms get permanently into the sea case 1, which then and reed lay times with low current in the sea box 1 and its internals.
- the guide rail 11 is on the inside of the outer skin of the sea case
- Fig. 3 shows the arrangement of the low-temperature sea chest cooler
- FIG. 4 shows a possibility of direct heating of the sea tank 1 via the high-temperature tube bundle 9 of the high-temperature circuit or the cooling water circuit of the diesel generators with an inlet temperature of at least 70 ° C. which is integrated in the so-called combination cooler Construction takes place according to FIG. 1.
- the local and temporary short-term overheating with closed inlet and outlet slots 8; 3 takes over the integrated high-temperature tube bundle 9 in the same way as described below under Fig.5.
- Fig. 5 shows the P&ID diagram for an engine with separate high-temperature and low-temperature cooling water circuits.
- the high-temperature engine cooling water is cooled back via the plate heat exchanger 14 in normal operation by the low-temperature cooling water, which in turn absorbs its amount of heat via the low-temperature sea case cooler 2 to the sea water when the inlet and outlet slots 8 are open; 3 leads away.
- the overheating operation for the low-temperature sea case cooler 2 is started to the minimum 60 ° C. necessary to kill the growth organisms.
- the bypass of the temperature control valve 16 is completely closed.
- the high-temperature cooling water heats up the low-temperature cooling water via the plate heat exchanger 14.
- the sea water in the sea box 1 is briefly overheated locally for a certain period by the low-temperature cooling water circulating in the closed circuit to at least 60 ° C. via the low-temperature sea box cooler 2, so that the growth organisms are killed.
- FIG. 5 also shows a proposal as to how the heating-up time can be shortened by means of a heat exchanger 15 additionally integrated in the low-temperature circuit and heated by steam, thermal oil or electrical energy.
- Fig. 6 shows a further embodiment as a displaceable, to the outer skin ontur adaptable elastic plate 17 as a waterproof closure device for the inlet and outlet slots 8; 3.
- the static pressure acting on the plate 17 from the outside presses the plate 17 against the outer skin designed as a double shell 18 in this area of the sea case 1.

- the Seekasten IB with the associated connecting pipelines, fittings 21B; 22B, box coolers 2B pumps 20B are locally limited and briefly thermally overheated and thus protected against growth by microorganisms, macro organisms and their larvae.
- this subsystem After cleaning operation in the sea box IB, this subsystem is switched to sea mode by opening the blind 4B.
- the sea crate 1A which was previously active in maritime operations, is now being Procedure switched to cleaning operation.
- Subsystem A is now also limited locally to prevent fouling and briefly overheated thermally.
