Primary Equipment for Oil Recovery

1. An oil containment boom with handling and cleaning equipment

2. An efficient skimming unit with handling equipment and aggregates

3. Storage availability for recovered oil

4. Cargo Heater

5. Transfer systems (pumps, hoses, valves)

STATUS OF THE TRANSREC SYSTEM

The TransRec is designed for:• Oil recovery in heavy sea• Transfer of recovered oil in open seas• Emergency off loading of grounded vessels• Coast /beach line clean up• Off loading of sunken vessels• To be operated by one person• Designed for 24 hours operation

TransRec Umbilical

Weir skimmerhead features• Center buoyancy• Automatic skirt • More compact design• Reduced transit draft• Self priming• Water cut measurement• Emulsion thickness measurement• (Capacity measurement)• Only pump pressure regulated

Weir Skimmer – Wave compensated self adjusting weir

Oil recovery from sea surface

”Positive displacement” skimmer should be used when the viscocity of the emulsion is more than 10 000 cSt

• If we can ”see” and measure what we are doing during operation, we may increase the overall efficiency by a factor of 2

To operate ”blindfolded”, the equipment should have: oil thickness meter in the oil boom oil/water phase meter in discharge line oil slick positions from surveillance helicopter

Pt. 5 Ch 7 Section 12 – Recovered Oil Reception and Transportation

• B 104 The oil tanks and deck area, from where the operation is performed, are to be as far away from the accommodation as possible

• C 101 The following spaces are to be considered as gas dangerous spaces during oil recovery operations:

Tanks for storage of recovered oilEnclosed or semi-enclosed spaces in which pipe flanges, valves, hoses, pumps

and/or other equipment for handling of recovered oil are located• C 103 Gas- dangerous zones are:

Zones on the open deck or semi-enclosed spaces on the deck within a distance of 3 m from oil skimmer equipment, hoses and valves used for recovered oil handling, openings and air pipes from tanks for recovered oil and openings and ventilation outlets from gas-dangerous spaces

• D 101 The vessel is to be arranged and equipped so as to minimize the time needed to make it operational. This implies that systems and equipment for handling of recovered oil as far as practicable are to be permanently installed

• D 103 All electrical and mechanical equipment for use in gas-dangerous areas during oil recovery operations is to be certified for operation in gas contaminated atmosphere

• D404 The filling line is to be provided with means for injection of emulsion-breaking chemicals. The arrangement is to be so as to facilitate efficient mixing with recovered oil, e.g. By injection to the suction side of a pump. For tanks provided with heating coils the requirements may be dispensed with.

Handling of equipment on deck

- Bunker fuels for commercial vessels will normally; HFO 380- Some refineries will also export HFO with higher viscosities; HFO 680 

Oil property

When these bunker fuels form an emulsion, we will experience the extreme viscosities

Oil property

Weathering of HFO 680

- Crude oils may change into high viscous oils as the oil ”weathers” and start to form an emulsion. Lighter fractions of crudes evaporate- Weathering test of relevant crude oils should be performed

Driverless offloading of sunken vessels

Why do we need to empty sunken vessels?

• Oil will come to the surface sooner or later

• We must not leave the environment polluted

• It is possible to cleanup after our mistakes

• It is a question of attitude and priorities

How do we do this

• We will use the same tool, TransRec, as for the emergency offloading and oil skimming operation

• The umbilical will be connected to a ROLS unit, which will cut hole in the vessels tank and discharge the oil to the surface vessel

• The ROLS may also be used for injection of compressed air into tanks and for steam injection as well (heating)

Our target is to empty oil from sunken vessels in a safe and cost effective

solution

1. Survey of wreck

2. Identify the potential

3. For pollution

4. Plan the discharging of oil

4. Technical challenges conclusion

5. Safety during operation

6. Cost of operation

Survey of wreck

• Identify damage of wreck

• How many tanks that may contain oil

• How to attack the tanks, plan of the wreck

• Meassure the thickness of the hull plates

Identify the volume of oil in the tanks

• Measure difference in pressure in tanks

• Take oil samples of oil• Identify specific gravity• Calculate ullage

Dispersant

• This is for cleanup of small oil slicks drifting towards sensitive areas

• Limitations

• This is only effective within the first 24 to 48 hours

• The emulsion will become too viscous for the dispersant to mix

• Skimmer tools are available for all viscosities

• All functions should be remotely - Safety on deck, no people on deck

Conclusion

Cost in US$/ton• Emergency transfer 20 - 200

• Oil skimming from sea 40 - 400

• Dispersant 400 - 500

• Offloading of sunken vessel 500 - 1000

• Cleaning of beaches 3000 - 6000
