With tall, slab sides encasing a multideck configuration, the pure car/truck carrier (PCTC) has a characteristically high windage factor, influencing course- keeping, maneuvering and fuel usage. A new series of PCTCs at the top end of the capacity

Introducing Lean Shipbuilding to U.S. Yards

Lean times call for "leaner" boats and what better to employ than Lean Shipbuilding, which is known as a proven approach that shipyards can use to improve shipbuilding efficiency. It has the advantages of reducing defects while remaining responsive to change.

Net gains for yards

In today's tightly competitive, global shipbuilding environment, every opportunity has to be taken to squeeze cost out of the system, notwithstanding the considerable advances already achieved, especially over the past five years, in efficiency and productivity.
