With a substantial number of PSV / OSV units at present lying idle with their owners looking for new ways to put them to work, we are pleased to have recently successfully completed the engineering for two PSV / OSV conversion projects. For both of these the clients wanted to have the capability to temporarily accommodate up to 40 additional personnel in single and double cabins. We achieved this for the first vessel by adding an extra layer of superstructure to the existing arrangement to take 15 double cabins.
For the second vessel the optimal solution was to fit accommodation containers on the mezzanine deck for the required number of people.
To achieve this involved implementing the SPS (Special Purpose Ship) Code, which bridges the gap between cargo and passenger vessels with its focus on safety of the personnel on board. However, the major challenge for the team was to manage each vessel’s stability behaviour given the extra weight involved and its distribution. Upgrades on this scale also require significant changes to all the on-board systems, especially those relating to the safety of the personnel. Our team with its in-depth understanding of the SOLAS requirements and the way that they interact with each other is an effective partner to manage all these changes.
“Each project has its own peculiarities and achieving the SPS class notation will take any engineer out of their comfort zone, as one needs to deal with lots of moving parts, including a great deal of Class interaction,” explains Liviu Galatanu, Business Development & Integration Director of GLO Marine. “We have learned much from these projects but, most importantly, we have taken the experience and translated it into efficient work-flows and step by step guides, which now enables us to deliver SPS class notations quickly and cost-effectively,”
Conversions of this type are ideal for mid-life PSVs that can safely operate for at least another 10 to 15 years. The time saved by conversion versus new build is also considerable. The design and on-board mobilisation and installation works associated with assigning a SPS Class notation to a PSV usually takes no more than 6 to 8 months, depending on complexity. And if the design work is done with a high degree of accuracy, the actual docking times can be as little as 3 months or even less.
