Challenges of the Asian ferry market include large regional variations in cargo volume and composition, huge economic pressure on operators and unsatisfactory safety records especially in the developing countries, according to ship design company Deltamarin, who has answered these with its DeltaSAFER design family unveiled at the SMM 2016 exhibition in Hamburg.
DeltaSAFER is a family of safe and affordable new-built ro-pax ferries, Deltamarin said. The design combines cost-effectiveness with an exceptional level of safety in a modular platform developed to meet the needs of different kinds of routes.
The safety of the design is visible in various features. The selected set of the hull dimensions is characterized by a relatively large beam of 30 meters. This, together with enhanced subdivision of the spaces below the main deck (including a triple bottom and triple side structure below the main trailer deck) results in high intact stability and survivability in case of damage. A simplified layout of the passenger spaces allows for smooth embarkation and evacuation. A redundant propulsion system helps to tackle extreme weather conditions, while an optimized hull form ensures low accelerations in waves and reduced power requirements.
The hull shape and structure give not only hydrodynamic benefits but also reduced construction costs. This includes utilizing standard plate thicknesses and profiles as well as simple connection details, developed in cooperation with an Asian shipyard. Other cost-effective measures include aligning the interior standard with local expectations, and using a mix of several comfortable suites with a number of large common sleeping spaces for budget travelers. A selection of affordable equipment manufacturers has also been identified to keep the costs of the machinery
as low as possible.
The DeltaSAFER design family covers a wide range of combinations considering passenger intake, cargo capacity and speed. Three variations are available so far:
- DeltaSAFER25 – a “base case” design with high deadweight (9,800t), reduced speed 16kn design speed and 800 passengers. Other dimensions are Loa 188.8 m, B 30.0 m, T 6.4 m, and Lane maters 2,500 m.
- DeltaSAFER21 – a Sino-Korean version with higher speed (20kn), 2,100 lane meters for cargo and a capacity of 1,000 passengers.
- DeltaSAFER15 – a South-East Asian option with reduced cargo capacity (5,500dwt) but increased passenger intake of 2,000 people.
Other options, including a fast ro-pax ferry, are also currently under development. The available designs can be tailor-made according to specific client requirements. Deltamarin also
offers a comprehensive construction services package with full engineering, procurement and project management (EPCM) support for construction.
“We are confident that our DeltaSAFER design offers Asian ferry owners and operators a solution well-suited to safe transportation at a reasonably low cost. An added benefit is the possibility to suit any capacity requirement – something not available in the second-hand market,” said Grzegorz Mazerski, Project Manager for DeltaSAFER and R&D Manager at Deltamarin’s Poland office
