1.0 IN GENERAL WARNING ! This equipment is designed to cope with debris normally found at an oil spill site, and it can be dangerous if the safety precautions in this manual are not being followed. Do not use the equipment without being familiar with the safety instructions. The customer is responsible for accidents caused by the equipment, if the safety instructions in this manual are not being followed.

The DESMI off-loading pump, type DOP-250 DUAL (see dimension drawing and assembly drawing in the appendix), has been specially developed for a wide range of emergency and auxiliary pumping operations. It is designed for handling liquids of an extremely high viscosity, like heavy crude oil or molasses, as well as low viscosity liquids as diesel fuel or water; and it will cope with debris normally found in oil spill sites. Nevertheless the pump will handle any medium very gently, without mixing or emulsifying e.g. oil and water.

Examples of applications are:

Χ Emergency off-loading of heavy crude, bunker oil or emulsions Χ Transfer pump in oil recovery systems (Skimmers) Χ Cleaning of oil pits Χ Emergency fire fighting Χ Auxiliary discharge or ballasting Χ Emergency bilge pumping

WARNING! When using the pump in hazardous atmospheres, always follow the instructions in section 4.4.

The DESMI DOP-250 DUAL is in its basic design a modified Archimedes' screw pump. It is the only one in the world in vertical design, meaning that the pump medium is forced into the pump by means of the end of the screw. Inside the DESMI DOP-250 DUAL pump the pressure is built up between the screw and the engaging plate wheel. In order to withstand this pressure and the wear caused by abrasive media, the plate wheel is specially designed: A high-tensile steel core carries easily replaceable sectional discs of polyethylene.

The high maximum discharge pressure (10 bar/150 psi) results in very big axial forces on the bearings. This is overcome by a set of SKF conical roller bearings. The roller bearings also function as bearings for the hydraulic short motor which transfers power to the screw via internal splines in the screw shaft. For lubrication and protection the bearing housing is pressurized by the hydraulic drain line, which must always be connected during operation.

CAUTION ! In order to balance the internal pressure in the bearing house against the discharge pressure of the pump, the hydraulic drain line is equipped with a 5 bar/75 PSI check valve. Do not remove the check valve as this may cause damage to the shaft seal.

The DOP-250 DUAL off-loading pump is designed with no bearings on the inlet side. This design makes it easy for the screw to “catch” even extremely high-viscosity media. To seal between the screw and the pump casing and to withstand abrasive media, the casing is equipped with a replaceable polyethylene sealing ring.

The pump is available in one version. For emergency off-loading and for dry permanent installation. The materials are in seawater resistant aluminium/ni-resist steel (screw). Further the pump is equipped with a sharp cutting devise which will cut almost all types of floating debris such as 1/2” nylon rope and 1½” pine dowels, cans bottles etc. The pump is able to pump debris up to 1 1/2” in diameter.

2.0 TRANSPORTATION AND MOUNTING

2.1 Transportation of the pump

For easy transportation, the pump is equipped with a lifting eye (Fig. 1).

CAUTION! Do not lift the pump in other parts than the lifting eye or the carrying handles!

Weight: Aluminium/Steel 80 kg / 176 lbs

Fig. 1 - Transportation of DOP-250 DUAL pump

2.2 Mounting WARNING ! Always keep a safety distance to the pump of minimum 2 m/7 ft. when the pump is connected to the hydraulic power supply. Do not connect the hydraulic hoses to the power supply until you are ready for operation.

The pump is fitted with either Tema or Aeroquip quick couplings for easy connection of the three hydraulic hoses. One connection for hydraulic pressure, one for hydraulic return and one for hydraulic drain.

CAUTION! Always remember to connect the hydraulic drain line, otherwise the hydraulic motor will be damaged.

NOTE! When mating quick couplings, check that the O-ring inside the lip of the female fitting is properly seated before inserting the male fitting. Carefully align the fittings before pushing them together to avoid damaging the O-ring. If the fittings do not couple on the first try, check the O-ring before trying again.

LIFTING EYE

To connect the hydraulic hoses, take off the dust caps/plugs. Pull back the ring on the female coupling, and push the two parts together. Lock with the locking ring.

NOTE! Use hydraulic hoses with a length and dimension corresponding to the distance between the pump and the power station, to minimise loss of power.

E.g. if you are pumping 30 m (100 ft.) from the power station, use 40 m (130 ft.) hydraulic hoses. If you use more than a 20 m (66 ft.) hydraulic hose set, use 1" hoses.

Power loss for 1" and 3/4” hose sets (at a flow rate of 160 l/min-42 USGPM and hydraulic oil viscosity of 20 cSt):

Length of hose set:

3/4" hose

1" hose

3.2 kW

60 m (2 x 60 m)

20.4 kW

4.8 kW

80 m (2 x 80 m)

The pressure drop in a 10 m (33 ft.) 1" hydraulic hose is 1.5 bars (22 psi) at a flow of 160 l/min (42 USGPM) with a hydraulic oil viscosity of 20 cSt, equal to 0.4 kW - for a 40 m hose set 3.2 kW (both pressure and return line). For 10 m 3/4" hydraulic hose the pressure drop is 6.5 bars (95 psi) at a flow of 160 l/min, with a hydraulic oil viscosity of 20 cSt, equal to 1.7 kW - for a 40 m hose set 13.6 kW.

These considerations also apply to the discharge hose. Use as big a dimension as possible, and as short a hose length as possible - especially if pumping high-viscous liquids. The discharge hose is also equipped with a quick coupling of either the Snabb or the cam-locking type. Roll out the entire hose, and lay it flat on the ground without kinks and twists. Connect the hose to the pump.

3.0 Response Tactics

The DOP-250 DUAL pump is used in a wide range of applications including as an off-loading or transfer pump. Among other things RO-CLEAN DESMI supplies the below equipment and special adapters for the proper use of the pump:

- DESMI-TERMINATOR skimmer. The self-adjusting weir skimmer head for

open sea skimming of spilled oil or for stationary use in extremely high-viscous oil with manual or mechanical feeding into the hopper.

- DESMI-TARANTULA high capacity skimmer. This self-adjusting weir skimmer

is equipped with two DOP-250 DUAL pumps and is used for open sea skimming of spilled oil.

- DESMI-SWEEPER. The hydraulic crane adapter for beach cleaning, open

barge off-loading, waste pit pumping, etc. - DESMI DOP-250 pumps are supplied as standard off-loading pumps in more

than 20 established oil recovery systems world-wide.

NOTE! Response tactics for these systems are discussed in the relevant operation manuals supplied with each system.

3.1 Field operation of the DOP-250 DUAL pump alone:

A. In General:

- During tank, pit or barge off-loading, lower the pump as deeply as possible into the oil/emulsion.

- Avoid sucking air as this will reduce the pump efficiency, especially on highly

viscous media.

- During beach cleaning the pump should be positioned in such a way that a sufficient flow of oil to the inlet is obtained. Dig a hole if possible, but be sure to keep the inlet 8-10 inches above the bottom to minimise the amount of stones and sand entering the pump.

- IN ALL SITUATIONS, run the pump as fast as possible without causing

cavitation due to vacuum on the suction side. You may hear a loud "banging" noise when the pump is cavitating.

NOTE! Operating the pump at high RPM allows the pump to better cope with large debris.

B. Tank Off-Loading:

WARNING! When using the pump in an explosive atmosphere, always follow the instructions in section 4.5.

NOTE! When pumping non-oily media, grease the plate wheel bearings every 8 hours of operation using the grease nipple on the plate wheel shaft.

The DOP-250 DUAL pump will go through a hatch or manhole with a diameter of

600 mm/24".

It is strongly recommended to use the following equipment: - A crane or a tripod - A lifting wire with straps to fit*) - A discharge hose with straps*)

*) Alternative: Separate lifting reel for discharge hose

In this way there will be a uniformly distributed lift in the discharge hose, and the lifting eye of the pump will not have to carry the weight of the hoses filled with liquid.

3.2 Deployment:

1. Connect the lifting wire to the pump.

2. Connect discharge and hydraulic hoses to the pump.

3. Snap or tie the first couple of hose straps to the wire straps. Depending on the depth of the tank, it may be necessary to tie up the hydraulic hoses too.

4. Lift up the pump and hoses by crane or tripod and start lowering into the tank.

Snap or tie up the wire and hose straps as they are entering the tank. 3.3 Employment: See Section A above. 3.4 Recovery:

1. Disconnect the hydraulic hoses at the power supply

2. Start lifting by crane or tripod.

3. Disconnect the strap-connections one by one as they reach the hatch or

manhole opening and reel up hydraulic and discharge hoses. It is recommended to incorporate the outside cleaning of the hoses in this procedure.

4.0 OPERATION WARNING ! WHEN OPERATING: A safety distance to the pump of minimum 2 m/7 ft. must be observed by all personnel when the pump is connected to the hydraulic power supply. Also when the pump is not running.

4.1 Before Operation WARNING ! Keep away from the rotating pump screw and cutting knives. The pump screw/cutting knives are designed for cutting debris normally found at oil spill sites and will also cut off fingers and other limbs.

CAUTION! The pump should not run dry for more than a few seconds, just enough to check direction of rotation.

D. To ensure maximum performance, the pump must always be fully sub-

merged (to avoid sucking air).

E. If the pump stops due to excessive debris/solids, simply reverse the pump to discharge the blockage.

WARNING ! If it is necessary to remove debris from the pump by hand, stop the skimming operation and disconnect the hydraulic hoses at the hydraulic power supply. For safety reasons, always keep a distance to the pump of minimum 2 m/7 ft. when the pump is connected to the hydraulic power supply.

4.3 Recovery After Operation

WARNING! Always keep a safety distance to the pump of minimum 2 m/7 ft. when the pump is connected to the hydraulic power supply.

A. The contents of the discharge hose may be discharged by means of the

pump: Empty the discharge hose by slowly and carefully reversing the pump.

CAUTION! Take care that the discharge hose is not being sucked into the pump as this will result in severe damage to the hose.

If possible lift up the hose with a crane so that the liquid runs back to the pump. The contents of the discharge hose may not be discharged by means of the pump: Flush the hose using diesel and water with the pump in pumping mode.

B. Before recovering the pump after operation, disconnect the hydraulic

hoses at the power supply for safety reasons.

C. Follow the instructions in section 4.4.

4.4 Inspection after Operation

WARNING ! Keep away from the rotating pump screw and cutting knives.

E. Connect the pump to the hydr. power supply and restart the pump at low

RPM and slowly pour 1 to 2 litres of lub. oil or corrosion protection oil into the outlet to preserve the inner parts of the pump. Let the pump work with the oil for 2 minutes. Wait for 15-30 minutes and empty the pump again. Keep the safety distance! Disconnect all hydr. hoses.

F. Check the hydraulic connections for leaks. Tighten, if necessary.

G. Clean the quick couplings and protect them against corrosion using

corrosion protection oil. Fit the protection plugs on all couplings.

4.5 Explosive Atmosphere

NOTE! The DOP-250 DUAL pump in its standard version is safe for use in Combustible Liquid Class D and E (as defined in CFR Title 46, part 30.10-15) following the operating procedures outlined in this manual.

WARNING: When pumping liquids with a low flash point, do not start pumping unless the entire system (pump, hydraulic hoses, discharge hose and power station) has been adequately grounded. Do not disconnect ground wire during operation. Failure to follow this warning can result in ignition of flammable vapours, and thereby explosion, caused by static electricity. Follow these safety precautions: Χ Remove stator cutting knife from pump inlet. Χ All components of the system must be electrically connected. Bond the

pump and the discharge hose to the power supply. Bond the power supply to the deck. Bond the tripod to the deck.

Χ Do not free fall liquid into a tank. Χ Make sure that the pump is completely submerged during operation. Χ Operate pump as slowly as possible. Increase and decrease pump speed

slowly.

CAUTION! The DOP-250 DUAL pump can be safely used in flammable liquid grade A, grade B and grade C (as defined in CFR Title 46, part 30.10-22) operation under the following conditions:

A. Follow all operating and maintenance instructions in the Operator's Manual.

B. Before operation, check that the pump is properly maintained and in good condition. Worn or damaged wear parts (polyethylene sealing discs/sealing ring) must be replaced.

C. Remove stator cutting knife from pump inlet.

D. Ground the pump casing via its own individual cable, or via internal grounding

cable in discharge hose fabric. In any case: Attach ground wire directly to casing using any assembly screw.

E. Ground the hydraulic motor via its own individual cable, or via the internal

steel reinforcement in the hydraulic hoses. In any case: Attach directly to hydraulic motor using one of the screws that flange the motor to the pump casing.

F. As the hydraulic motor casing is made of cast steel, precautions must be

taken in order to prevent it from direct contact with other steel items in the danger area. This could be overcome by covering the motor with a shield of aluminium or plastic.

5.0 PREVENTATIVE MAINTENANCE

Equipment for combating oil pollution should be treated as emergency equipment. It should be maintained and kept in a state of readiness in the same way that fire-fighters handle their gear. It is too late to inspect and repair this gear when the "alarm bell" of an environmental emergency rings.

5.1 Necessary Tools and Supplies:

2 pcs. 10 or 12 inch adjustable (depending on type of hydr. quick couplings)

1 pc. metric CH-screw spanner set (inner hexagonal)

1 pc. screw driver, medium size

- corrosion protection oil

- thread-compound (e.g. "THREAD-EZE" from CHEMSEARCH), to protect screws and aluminium from “growing” together

5.2 After Operation (including training exercises): CAUTION! No matter how many hours a pump is operated, it must always be inspected afterwards as described in paragraph 4.4.

5.3 Between Operations and During Storage:

It is necessary to perform paragraph 4.4, items D, E, F, and G every 6 to 8 weeks when the pump is not used. It may be convenient to use the same inspection/-maintenance intervals as for the power station.

5.4 Hydraulic Motor and Bearing Casing:

The hydraulic motor and bearing casing are integral parts of the hydraulic system and need no preventative maintenance under normal conditions. The motor and bearings are designed for thousands of hours of operation provided that the hydraulic fluid is properly filtered and contamination is kept below the levels recommended by the hydraulic motor manufacturer.

B. Unscrew the four screws (item 31) and

lift up the motor. (Fig. 16) Wrap the complete motor arrangement

in plastic film for protection. Please observe the blue conical sealing ring that seals between motor and pump screw shaft. The bigger diameter must always be on the motor side. This seal ensures that the drain oil from the motor is led into the spline connection between motor shaft and pump shaft for lubrication. From there the oil is directed inside the shaft to a position under the main bearings. This ensures a continuous flow of new oil to the roller bearings. Via a hole in the motor casing, the drain oil is led through the 5 bar/75 psi check valve and into the drain line.

C. Mount a new O-ring (item 33) on the

new or repaired motor for proper sealing between motor and bearing housing. (Fig. 17).

D. Mount the new or repaired motor

Fig. 18

Fig. 19

Fig. 20

NOTE! The conical roller bearings are designed for several thousand hours of operation. If they need to be replaced, you should look for a reason why:

1. Quality/cleanliness of hydraulic oil OK ? 2. Is the 5 bar/75 psi non-return valve on the drain line in position ? 3. Has the pump been running without the drain line connected ?

Reasons 2 and 3 could cause damage to the shaft seals (item 20), thus resulting in damage to the bearings.

G. Replacement of the shaft seals is easily done after unlocking the lock ring (item 27). Please observe that two sealing rings turn the opening towards the bearing housing and one turns towards the pump medium. Grease the sealing rings (item 20) carefully.

H. Inspect the shaft for damages in the sealing area. Repair, if

necessary/possible, or replace the shaft.

I. Assembly is done following the instructions A-G in opposite order, but observing the following: After inspection/replacement of the roller bearings onto the pump screw shaft, the lock nut (item 42) must be tightened until the outer rings of the bearings are difficult to turn. Then loosen the lock nut approx. one (1) step and check that the outer rings will rotate.

A toute modification d’une ou de plusieurs pièces des moteurs correspond un changement denuméro de série.Les moteurs OMT portent leur numéro de série à la suite de la date, par example: xxx-2

Efter uge 32.97 er spændestift flyttet. Ved reparation af motor fremstillet før 32.97 skal ende- dæksel, balanceplade, spændestift og fjederskive skiftes.

After week 32,97 the tightening pin has a new location. When repairing motors manufacturedbefore week 32.97 it will therefore be necessary to replace end cover, balace plate, tighteningpin and spring washer.

Der Spannstift hat nach Woche 32.97 eine neue Plazierung. Bei Reparaturen von Motoren dievor Woche 32.97 gefertigt wurden, müssen deswegen Enddeckel, Ausgleichplatte, Spannstiftund Federscheibe ausgewechselt werden.

À partir de la semaine 32.97, la pièce de serrage occupe une nouvelle position. Lors d’uneréparation sur un moteur fabriqué avant la semaine 32.97, le couvercle d’extrémité, la plaque decompensation, la pièce de serrage et la rondelle à ressort devront être changées.
