Perth-based TSMarine Pty Ltd has been awarded a contract by Nexus Energy Ltd to complete the Longtom Field Installation. It will be the second project executed by the recently formed TSMarine DOF Subsea Joint Venture (JV) combining TSMarine's DP2 DSV Rem Etive vessel with the DOF Subsea D300 saturation diving spread.
The work scope includes the final metrology then installation of 12 rigid tie-in spools and protection structures, installation of a flexible flowline jumper plus hydraulic and electrical flying leads followed by dewatering and hydrotesting of the Longtom pipeline. Saturation divers will be used for the majority of the work in 57m water depth.
The Longtom Field, located off the South East Coast of Victoria in the Bass Strait in Australia, will be tied into the existing subsea Patricia Baleen development. The offshore work is expected to take approximately 30 days (excluding any allowance for weather downtime) and will commence immediately following the DSV Rem Etive's existing commitment performing a 42" - 24" hot tap and associated rigid spool tie-in's in Malaysia, the first project to be performed by the new joint venture company.
The DSV Rem Etive has a comprehensive NOPSA accepted Safety Case covering a wide range of offshore activities, a 12 man saturation diving system, two high specification work class ROVs, approximately 550m² clear back deck and a 140 tonne active heave compensated knuckle boom crane. The vessel has a significant track record of working in Australasia, including Bass Strait, and South East Asia.
The TSMarine DOF Subsea JV DSV Rem Etive offers the Australian and South East Asia region an unrivalled level of capability and specification. Furthermore, the DSV spread is offered in conjunction with the project management and engineering support required to successfully complete an offshore project.
