The vessel, a Wärtsilä Ship Design, is to perform diving support, subsea construction work, crane lifting and ROV operations.
Delivered in 2010, Hallin Marine’s Ullswater is a 78 m DP2 Subsea Operations Vessel equipped with a 15 man saturation diving system and a 50 tonne offshore crane for subsea work.
The vessel is equipped with the Super Trident Sewage Treatment Plant ST10C, certified to meet IMO MEPC 159(55) guidelines. Optimised for the treatment of black and grey wastewater flows, and suitable for conventional gravity and vacuum fed collection systems, the Wärtsilä Hamworthy Sewage Treatment Plant is controlled automatically.
