Retrofit & conversions

Changing the vessel’s purpose or making a significant change to its capabilities is always a big engineering challenge. Luckily, our background is ship repair and new building yard support. We know the importance of precise design, preserving the unit’s safety, being on schedule and providing great customer service during the survey, repair, and conversion.

Our experience in this field, among other projects, includes the conversion of OHT’s Albatross from an oil tanker to a heavy lift vessel. To carry out such a significant shift in mechanics, size, and shape of the ship successfully, our team needed to pair the decades-long experience of the project’s chief designer with the most contemporary software. Having executed advanced calculations and precisely planned every step of the construction, they managed to preserve the ship’s stability and prepare it for its new duties.
