Three Ship, Multi-Phase, Multi-Continent Conversion
McDermott International entrusted Allswater with the ambitious task of converting three vessels—two cable layers (Emerald Sea & Agile) and one platform supply vessel (Thebaud Sea)—into offshore construction vessels. This multi-phase, multi-continent project spanned four years, with work conducted in Canada, Dubai, Singapore, and Indonesia.
Solution
Allswater’s strategic Atlantic Canadian location proved advantageous for international collaboration. Being four hours behind the UK and two hours ahead of Houston allowed the team to address issues with European suppliers before the start of the workday in the US.
Each of the three vessels was carefully redesigned to optimize their capabilities in their new construction roles. Significant installations and upgrades included:
- Helideck installations
- A large moonpool
- Cable carousel
- New machinery spaces
- Saturation Dive Support system
- Accommodation units
- Crane installations
In addition to engineering work completed at Allswater’s Halifax office, onsite support was critical at each of the four work sites. Allswater personnel worked globally around the clock, ensuring efficient progress throughout the project.
Results
Allswater’s “all in” approach to partnering with clients ensured that the engineering and construction met operational considerations, project schedules, and budget constraints. As a result, all three converted vessels continue to support McDermott International’s offshore projects in the Arabian Gulf, Asia, and Brazil.
