HydroComp’s technical director Don MacPherson explains the steps involved in the hullform optimisation for a LNG-fuelled Ro-pax project that forms part of the EU-backed Poseidon Med II initiative


It is fair to say that the production of greenhouse gases, particularly CO2, has become a major design driver for naval architects. Regulation has mandated limitation of emissions, and we are also seeing owners voluntarily taking steps to reduce harmful CO2 and to reduce their ship’s carbon footprint.

Recently, the owners of Blue Star Ferries put forth a challenge to Greek engineering company NAP Engineering P.A. and their subcontractors US-based HydroComp Inc. to do just that. The project was part of the EU co-funded Poseidon Med II Deliverable 14.4, which called for a compact LNG-fuelled Ro-pax ferry design. The vessel was limited to 145m length overall and was to carry 1,400 passengers and provide for 1,000 lane-meters of automobile and truck capacity. Additionally, the vessel was to comply with SOLAS, ‘Safe Return to Port’, and IGF Code Rules and Regulations. The design has already received
Approval in Principle (AIP) from Lloyds Register.
