Strong second-quarter improvements this week have met or surpassed the positive predictions issued in the first quarter by US-listed offshore vessel owner and charterer Helix Energy Solutions.

Helix chief executive Owen Kratz said in the first quarter of 2018 that the market had passed the bottom, with the greatest potential to come after this year.

Although his company's latest numbers managed to surprise analysts during a conference call this week, Helix remained on the conservative side and did not adjust its full-year estimates.
