The Multiplier Effect: How Pump Efficiency Turns Your Next Drydock into a 25% ROI Machine

Drydock is no longer just maintenance – it is the single biggest strategic investment window in shipping. When you integrate pump efficiency upgrades (IE4/IE5 motors + VFD) with hull coatings, propeller work and ESDs during the same docking, total fuel savings jump from the usual 12–18 % to 20–25 % through powerful physical and economic synergies.In this episode I explain why treating pumps as “auxiliary works” is one of the most expensive planning mistakes in 2026, how the multiplier effect actually works, the real ROI numbers and what the best fleets are doing differently right now.You’ll learn:

• Why combining pump upgrades with hull/propeller measures creates a true multiplier (not just addition)

• Concrete savings examples and payback periods (often 12–24 months)

• How this directly improves EEXI, CII ratings and reduces EU ETS + FuelEU Maritime costs

• The practical 12–18 month planning framework and cross-functional decisions that turn drydock into a competitive advantage
