A shipowner earned substantial savings in a re-coating project having DNV calculating the areas to be coated. DNV's figures represented a 20 % reduction in the coating area estimate for a particular supplier, and a corresponding reduction in the final re-coating offer.
A major tanker shipowner was to evaluate offers for re-coating a VLCC. Both the aftpeak, forepeak and several ballast tanks were to be re-coated. DNV Nauticus provided the shipowner better control over the planning process for the maintenance job. With a total re-coating area in excess of 70,000 sq. metres and a unit price of around USD 30 per sq. m. for this type of job, the direct savings as a result of accurate area calculations were substantial.
The shipowner originally received offers from seven suppliers, and three of them were short-listed. The offers from the short-listed companies included a price, based on the supplier’s estimates of the areas to be re-coated. However, the coating area estimates ranged from 70 to 150 %, taking the 'middle estimate' to be 100 per cent.
The shipowner came to DNV to get assistance in finding the best offer. Using DNV Exchange Nauticus and the three-dimensional graphic model, the areas to be re-coated were calculated to be 76,000 sq. metres. The calculations were imported into a MS Word document together with illustrations of corresponding tanks and structural elements, all directly available from DNV Exchange Nauticus.
With the DNV report under his arm, the shipowner approached the supplier with the best offer. They agreed to use the report as a starting point for the negotiations with regard to the final scope and price for the job.
