FutureShip to optimise UASC newbuilds

United Arab Shipping Company (UASC) has partnered with FutureShip on a project to find the most efficient design for its future containerships.

When the shipping line decided to order new 14,000 TEU and 18,000 TEU vessels it invited various shipyards to submit their designs. The four shortlisted builders then provided detailed information so that FutureShip could assess the hydrodynamic performance of each design.

FutureShip, a GL company specialising in maritime consultancy and engineering services, calculated the total costs of transport per container-mile.

The four sets of design for both 14,000 and 18,000 TEU ships went through numerical tank towing tests based on Computational Fluid Dynamics (CFD) simulations. FutureShip ran thousands of tests to determine the speed-power relationship for the two ship classes.

Hyundai Heavy Industry (HHI) outperformed the competition in the 14,000 TEU category and also designed the most efficient single-skeg vessel at 18,000 TEUs, DNV GL reports.

UASC signed a letter of intent following the tests and HHI proceeded with the design, enrolling FutureShip for formal parametric optimisation with the objective of reducing fuel consumption as much as possible.

More than 35,000 hull shape variants were investigated for each hull design, says DNV GL. For final validation, professional model tests were conducted at the Hamburg Ship Model Basin.

UASC has now ordered five 14,000 TEU vessels from HHI, with six on option, and five 18000 TEU vessels with one on option. The new ship designs are currently being finalised at HHI with deliveries scheduled between 2014 and 2016, including all options.

UASC has also decided to implement FutureShip’s ECO-Assistant, an interface which selects the most efficient trim for every voyage.

DNV GL started operating as one company in September as a result of the merger between Det Norske Veritas (DNV) and Germanischer Lloyd (GL).
