THE CHALLENGE

The MSC Napoli was damaged in storms while sailing from Antwerp to South Africa. The 62,000-tonne vessel was carrying around 2,300 containers. The salvage operation cost in excess of £50m. The problem we were asked to solve involved the removal of the contents of the hold, some of which had become contaminated with Heavy Fuel Oil (HFO). The ship was to be cut into small sections to be recycled. The hold of the ship contained Barley, Soya beans, Chalk and various items such as shampoos and tyres. Additionally due to the breach in the ships hull, the holds contained significant quantities of sands and silts. All of the material had been contaminated with large quantities of HFO’s.

 


 
THE SOLUTION

The ship had over 200t of various materials which required identification and classification. We were able to separate the various wastes into Hazardous, Non-Hazardous and Inert. Some of the wastes were contaminated with oil from the on board fuel tanks. This material was in a semi liquid state and exceeded the guidelines for landfill. The solution was to utilise a unique remediation strategy using stabilisation which required trial batches being completed using a variety of stabilisation blends.

These stabilised products were analytically tested to meet the very stringent landfill Waste Acceptance Criteria (WAC). The newly created material was accepted by one of our partner companies, Impetus Waste Management and transported to Teesside for disposal. The remaining waste on the ship was classified non hazardous or inert and a local solution was sourced to offer best value for money. Contaminated water was treated using industrial oil absorbent booms and tankering.


 
THE RESULTS

We delivered the project within the agreed time scales and on budget
Our unique stabilisation ensures compliance with waste legislation for fully legal disposal.
Wastes successfully divided into various waste streams ensuring excellent value for money.
