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.

CONVERSION TO YACHT


CUSTOMER: Ocean Research Group
LOA: 67.28 m
MAX SPEED: 11.40 kn
DEADWEIGHT: 937 T
MAIN PURPOSE: private pleasure yacht

The vessel was an ocean research vessel, formerly an offshore supply vessel that was reactivated and converted originally in 2005 (M/Y Paladin Shadow) in 2006 (M/Y Peaceful Fish) and again in 2011 (M/Y Save Our Seas). The vessel is classed by Bureau Veritas as private pleasure yacht and the classification is to remain the same.

SCOPE OF THE PROJECT:

  • Adding a new deck dedicated to the owner's use - with the owner's stateroom, private lounge, gym, and spa,
  • Creating a movie theatre,
  • Upgrade of the audio visual and IT system,
  • Relocation of the helipad,
  • Creating of a new open sun deck,
  • Adding an elevator serving all decks.

LOA: 185.50 m

Edvard Grieg is an oil field in block 16/1 in production licence PL338, in the North Sea, 180 kilometres west of Stavanger. It is operated by Lundin Petroleum.

The topside consists of a main deck module, a combined utility module and living quarters, a process module and a flare tower. The main deck module and the combined utility module and living quarters have both been moved to barges at Stord, ready for tow-out to the field. The process module is also ready on a barge at Aker Solutions in Egersund, Norway, and the flare tower is completed and ready for delivery directly offshore from the subcontractor in Poland.
