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.

C4D software helped a client save US$ 400K

A container ship suffered bottom damage due to grounding. Two shipyards were contacted to evaluate the damage and provide repair estimates. But the estimates of the amount of steel required for repairs varied by 40%. An accurate assessment of the actual extent of damage extent and required repair material was urgently needed.

The case is real and happened to a PhDsoft client, a major company that operates ships in Brazil. In a few hours, using the repair tools of C4D Software®, the steel requirements were recalculated, showing that actual repair needs were 61 tons of steel, 60% less than the high estimate. It was clear that the shipyards significantly overestimated the amount of steel to be replaced.

Considering the cost of steel renewal in local shipyards of $11K/ton, the result was a saving of $400k. With the actual figure at hand, the client could safely and confidently select the shipyard with lower price and avoid the risk of the scope of materials increasing during repair execution.

“Without C4D Software we would have been forced to blindly follow the quotation of the shipyards with no control over the situation. Without C4D we never would have received the accurate numbers in time to make the right decision. The calculation of steel renewal done by C4D Software is more accurate than the shipyard because it takes into account all the original thicknesses”, stated the company.
