How to avoid unexpected expenditures on painting maintenance

During the preparation of the painting repair specification for the next dry dock of one container ship, an experienced engineer from a PhDsoft client realized the painting areas might had been underestimated. They were using figures from the design information booklet approved by the internal supervision team and classification society, and thus were supposed to be correct. The complex shapes of the tanks would make it unfeasible to recalculate manually.

The painting areas were recalculated in a few hours using the painting tools of PhDC4D®. Errors ranging from 20% to 260% were fixed. The fore tanks had the largest errors due to more developed forms.

As a result, an accurate painting repair specification was prepared and thus avoiding large unforeseen expenditures on repair execution; accurate amounts defined previously allowed a better base for price negotiation with shipyard; and the repair budget became accurate.

“We would never reach a conclusion without the help of C4D® since a lot man hours should be used for recalculating. It would be impracticable. It makes sense now why we always spent much more paint than initially planned. We thought it was due to inefficiency during the painting work. Why no one else detected this error previously during the plan approval process?”, stated the company.
