CNCo 40,000dwt Multi-Purpose New Buildings
 |
| CNCo K-Class 40k |
The China Navigation Company has contracted to build six 40,000dwt multipurpose (MPP) vessels at Nantong Mingde shipyard in Jiangsu province, China. CNCo has cooperated closely with Shanghai design house, SDARI, to create a design which combines an extremely efficient hull form with utmost operational flexibility to produce a vessel employable in the majority of Swire Shipping’s liner trades. The 40,000dwt ship will be the largest MPP in operation; 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 whilst 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.
