Creating the winning formula for energy efficiency and carbon neutrality is imperative for the maritime industry. Therefore, the IMO's has set indicative industry targets: Co2 neutrality by 2100. Every effort towards a greener future counts. In this webinar session, the energy efficiency expert Teemu Tanninen (Foreship) and industry experts Roberto Chiesa (GF Piping Systems) and Julian Backes (GF Piping Systems) discussed how even seemingly small components can significantly impact the energy efficiency, and fuel consumption of a vessel.​

On March 8 and 9, 2022, our experts discussed the saving potential with HVAC applications on cruise ships: What impact does the choice of the piping material have on the energy efficiency of the AC chilled water system on cruise ships? Our experts answered this question by presenting results from comparing a cooling system operated with traditional metal piping systems versus plastic piping systems.​

Key Take Aways Webinar

In the face of many looming sustainability goals, shipowners, shipbuilders, and dockyards require light, durable, efficient, and cost-effective technical solutions that they can implement throughout their vessels. In this context, HVAC systems are an area with a lot of potentials as they often still rely on traditional steel piping systems with insulation techniques that do not reflect the state-of-the-art technologies currently available. It was therefore the goal of this study conducted by GF Piping Systems and Foreship to compare pre-insulated plastic and post-insulated steel piping systems in air conditioning chilled water systems onboard cruise ships. Find the most important findings and takeaways below:

Fuel reduction of up to 112 m tons

Fuel reductions

The up to 30% higher energy efficiency of the pre-insulated polyethylene piping system COOL-FIT (compared to metal alternatives) translates to a measurable environmental impact. Due to the lower power requirements, fuel savings range between 82,1 m tons/year (for an LNG ship with variable flow pumps which also saves 2,0 m tons of pilot fuel) and 112,5 m tons/year (for an MGO ship with constant flow pumps).

Greenhouse Gas Emissions (GHG)

Pre-insulated plastic piping systems require lower fuel consumption, which leads to measurable financial savings. Over the course of 25 years, pre-insulated plastic piping in air conditioning chilled water systems can save an average $2,3 million, considering an annual inflation rate of 2,5%. However, shipowners can expect a total of around $3,8 million in savings as COOL-FIT is maintenance-free which drastically lowers operational costs.

Reduction of GHG emissions
Estimated cost savings of up to $3.8 million

Financial Savings

Depending on the configuration of the vessel, 306,8 m tons to 373,7 m tons of CO₂ can be saved every year by using non-corrosive, lightweight pre-insulated plastic piping systems instead of post-insulated steel piping systems. Other pollutants such as Nitrogen Oxides (NOX), Sulfur Oxides (SOX), or Particulate Matter (PM) can be reduced by 1,1 m tons to 6,1 m tons per year.
