The Sea Trucks Group is delighted to report the ongoing outstanding performance of its recently delivered multi-purpose DP3 crane / pipe lay vessel Jascon 25 in its first six months of operation supporting a major SURF installation project in NW Australia for the SEASTREAM Joint Venture.
In June the Jascon 25 completed several heavy lifts of subsea structures weighing between 650 and 710 tonnes. Capacity to make such lifts from SURF installation vessels opens up a new degree of flexibility in the design and layout of subsea fields in remote locations where specialised heavy lift facilities are not economically available. These lifts are perhaps the heaviest ever completed from a SURF vessel where the same vessel is then utilized for the remaining pipe lay, moorings and tie in and commissioning work scopes.
More recently the Jascon 25 commenced the installation of flexible flowline, riser and umbilicals. The vessel was able to install a 10" flexible production line in wind speeds of over 30 knots and significant wave heights exceeding 4 metres. In these weather conditions Jascon 25 remained stable and was able to safely continue operations whilst other SURF vessels in the same field location were on weather standby.
Fraser Moore, Vice President Operations of the Sea Trucks Group, commented: "The outstanding performance of Jascon 25 in its SURF installation mode during challenging weather conditions was a great achievement for the vessel, its crew and the Seastream project team. It is all the more remarkable when noted that the Jascon 25 is also able to offer our clients steel pipe lay installation (on DP), Floatel services with over 350 beds available and a very competitive transit speed.
We believe that this exceptionally competitive performance in the SURF market segment demonstrates the excellent capabilities of the vessel and shows the great potential of the Sea Trucks Group "hybrid" vessel design philosophy. We now look forward to the successful completion of this project."
