Spinning off shipbuilding: the founding of IHI Marine United (2002)

The weight of folding up the founding business

The heart of this spin-off lay less in the deftness of detaching one business, shipbuilding, than in the step of deciding to put outside the parent the founding trade the company had borne for half a century. The 1960 merger with Harima had meshed a land-heavy Ishikawajima with a sea-heavy Harima and was a choice to reach the summit by embracing the “sea” in strength. Some forty years on, the same company this time turned to the side of severing the sea it had once embraced. Pressed by an outside change — a structural recession — the process of cutting its lingering attachment to the founding trade and reassembling both vessel and partner reveals a management will that ceaselessly redraws the portfolio.

Still, the road to folding up shipbuilding did not end with a single decision. The agreement with Kawasaki Heavy Industries collapsed in five months; the partner was switched to Sumitomo Heavy Industries, and through a further re-consolidation in 2013, the founding trade at last withdrew to the outer rim of the consolidated group. The parent, lightened by the severance, drew its resources toward a new central axis, aero-engines. Yet the more it leaned on a single pillar, the more the pain grew when that pillar shook. What light and shadow the concentration gained by letting go of the founding trade would cast in later years was, at the moment of this spin-off, not yet visible.
