Benchmarking container ship designs

Saturday, 04 February 2012 | 00:00
A new tool for comparing a ship design against a database of similar designs is now available from DNV. We can benchmark your design against the whole world fleet or a selection of comparable ship designs based on technical, operational and environmental indicators.The PCT (Pre-Contract Tool) enables ship designs to be extracted from multiple databases such as IHS Fairplay as well as in-house databases, and can conduct various analyses and trend studies of the different ship segments and designs.
Some examples are given in Figures 1-3, where some main particulars are compared for a feeder container ship with a cargo capacity of 2200 TEU. Container ship design details have changed radically over the past few years even though the ships look quite similar. New operating conditions due to slow steaming and variable load factors have led to new ship dimensions, cargo capacities and propulsion power installed. As shown in Figure 4, vessels with a cargo capacity of 2000-2500 TEU have not had a main engine power per TEU ratio of above 9 during the past few years.
Similar analyses can be conducted for all size segments.
The IMO Energy Efficiency Design Index (EEDI) for new ships has led to increased attention to balancing speed and energy consumption with ship capacity. We can measure your fuel consumption and CO2 emissions in the perspective of your transport operations – in terms of a preliminary EEDI calculation (Figure 5) or actual emissions per year or per transported unit (Figure 6).
All of these areas are important when developing a new ship design, but could also be useful during due diligences, mergers, acquisitions or corporate financing processes. Together or separately, the different services offered can improve and promote the strengths and environmental advantages of your current or future designs.
Environmental awareness is increasing and, as a consequence, so is the need to demonstrate that vessels and operations are environmentally friendly. It is DNV’s belief that ship designers and owners seeking to be market leaders need to promote an environmental profile and to heighten their awareness of the ship’s design performance, environmental performance and carbon footprint.
