What HEBO looks back on with great pride were the various load tests we carried out for the Pioneering Spirit, the world’s largest crane vessel, in the Alexiahaven in Rotterdam.

With our experienced supervisors, ballast engineers and ballast crew, we took care of all the work on-site. The weight of the test pontoons varied from standard weights to up to 5500 tons. For the lighter load tests we used the P-34; for the heavier load tests (5500 tons) we used our P-41.
