System of Construction

Colorado Shipyard has expanded our services into the Ship Building and Construction Market. An example of our work is a recently completed Passenger/Cargo Combination Vessel called Tuhaa Pae IV. This is a 76 Meter 1,300 Dwt vessel designed in France. This vessel carries 100 passengers and 62 intermodal containers (20-foot equivalent unit containers) above deck and in the cargo holds. Both general purpose and insulated containers can be transported.

The ship meets all international operating standards including SOLAS and Marpol IV. Also, the vessel is fitted with two (2) deck cranes for cargo loading. The vessel is powered by two (2) 1,176 Kw Daihatsu 6D LM-26 Engines with Fixed Pitch Propellers.

We leveraged an extensive Ship Work Breakdown Structure (SWBS) System for Engineering, Planning and Monitoring Progress of the building project and uses the Hull Block Construction Method for shipbuilding.
