CNCo 40,000dwt Multi-Purpose Concept Design
 |
| CNCo K-Class 40k |
The China Navigation Company has cooperated closely with the Shanghai design house, SDARI, to create a new 40,000dwt multipurpose (MPP) vessel design which combines an extremely efficient hull form with the utmost operational flexibility to produce a vessel employable in the majority of Swire Shipping's liner trades. The 40,000dwt ships would be some of the largest MPPs in operation in the world; the dimensions carefully selected to ensure that the vessel can enter the majority of the world's conventional breakbulk ports. CNCo is confident that the low running costs [40,000dwt on 11.9m at 14.5 knots burning 30tpd of 380cst) of this efficient design, together with the economies on offer from the increased cargo carrying capacity, will enable this ship to gain popularity amongst other MPP owners, making it an MPP industry standard.

The two biggest cranes can be combined to lift 250 tonnes 12 metres from the ship’s side.
Cargo Carrying Capability
 The ship has a 5 hold 9 hatch formation with tween decks in hold numbers 2, 3 and 4. The box holds allow for easy drop stowing of break bulk cargo and the flush hatch covers are designed to allow the carriage of long pieces of project cargo such as wind turbine blades whilst being strong enough for the carriage of generators, turbines and large modules.
 The tank tops have been specially strengthened to allow for the carriage of two tiers of heavy steel coils. The ships will have a container capacity of 2300 nominal TEU.
