- 2. The Wellservicer’s excellent Dynamic Positioning (DP), station keeping and working weather limits provide a stable platform capable of suppor- ting a Vertical Lay System (VLS), carousel or reel mounted equip- ment. Verified to Norwegian standards, her innovative design and high degree of sophistication provide a cost-effective solution for a wide range of specialist services, including hyperbaric welding, flexible flowline, riser and umbilical laying, installation of structures, piling and mothership support for trenching and diverless subsea equipment. Seakeeping characteristics The vessel's outstanding success in the subsea construction market is attributable to the innovative mono- hull design with its passive and active stabilising systems, which provide a highly stable base for subsea opera- tions. These active damping and anti-heeling systems limit the vessel's The Wellservicer is a versatile multi-role vessel that combines heavy lift capability with either diver or diverless intervention support. motion to only 1 to 2 degrees of roll in a Beaufort 8 seastate. Cranage The vessel’s main telescopic pedestal crane is rated to a double fall capa- city of 200 Te at a radius of 26 m, with the auxiliary line capable of lifting 20 Te loads at a working radius of 33 m. The active heave compensation (AHC) and constant tension func- tion on the main hoist, ensure excel- lent control of loads during subsea lifting operations. Fitted with two 5 Te, 15 m, subsea rated knuckle boom cranes situated on the port and starboard of the vessel, the Wellservicer expertly handles a range of both subsea and onshore lifting operations. Remotely operated vehicles (ROVs) The vessel is fitted with a work-class Multi Role Vehicle (MRV) system Wellservicer Capabilities 2 Wellservicer

It is launched over the vessel’s starboard side utilising a Launch and Recovery System (LARS) located on the starboard mezzanine deck. This MRV system is operated from Dive Control, which is the hub of all vessel subsea operations. The Wellservicer also has a latest generation Observation Class ROV system located on the port mezza- nine deck. This “eyeball” system is equipped with state-of-the-art cameras and sensors. Diving system Designed with safety and flexibility in mind, the Wellservicer is fitted with a saturation diving complex rated to 450 msw, though currently certified to 300 msw, and capable of supporting up to 18 divers under pressure. The system comprises three 6-man twin-lock decompres- sion chambers (DDC) and two 3-man diving bells. The bells can be operated for on bottom turnarounds or indepen- dently and the system allows divers to be maintained at different working and decompression depths at the same time. Divers under pressure can be evacuated by means of a hyperbaric lifeboat positioned on the starboard side of the vessel. Facilities exist for air diving stations to be installed as required on the port side. Dynamic positioning system There is a fully redundant Kongsberg SDP 21 system with multiple inde- pendent reference systems. The vessel is able to keep position in up to 80 knot wind speeds and has a fully redundant power system. The vessel is also fitted with a Kongsberg SDP 11 back-up system to meet Norwegian Marine Directorate (NMD) DP Class 3 rules. Accommodation The Wellservicer's accommodation is spacious and comfortable, desi- gned and equipped to European standards and fully air conditioned. Client suites have both dayrooms and bedrooms with easy access to the large office and conference room.
