The unique operational advantage of the compensated NOV 165-metric ton AHC crane, in combination with the rig’s DP capability, makes a positive difference compared to many other units. Subsea operations, such as template installation and preparation spud of new well / top-hole drilling and P&A operations, can be done simultaneously with mooring activities.
The crane can operate in AHC mode down to 1200 meter water depth, and can therefore be very useful for subsea work on templates on sea bed, performing work such as:
First of its kind
The unit is the first of its kind, and is designed for North Sea operations. The Island Innovator is a fully equipped semi-submersible drilling unit based on proven design. Island Drilling is responsible for marketing and operation of the rig.
Island Innovator has been engaged in Harsh Environment drilling operations since 2013, and maintains an excellent performance record. Regularity in excess of 99% available rig for customer. Enhanced design with improved heave characteristics for reduced waiting on weather, Island Innovator is built to operate in the Barents sea. The rig has achieved good results in exploration, with several drill steam tests.
DP/MARINE: The rig has extensive experience with spudding on DP for station keeping while connecting to pre-laid anchors, before continuing in Posmoor ATA mode. The rig has also performed P&A of top-hole sections on DP. This capability reduces time spent on anchor operations with up to 2 days.
ROV: The ROV facilities, with integrated control room for ROV pilots and a well sized ROV hangar is functioning in an effective manner. The launching is set up by using a cursor system, placed close to the rig centre. Constant tension wires to pontoon enables the ROV to be launched up to 4 m significant wave height. Launching and recovery above 4 m significant is pending wave and wind direction.
Island Innovator is equipped with a NOV 4000 HP ram-rig type cylinder rig, with hydraulic active heave compensation and separate pipe racking tower. It has NOV BOP handling system and a five ram BOP stack from Cameron. The rig is purposely built for production drilling on subsea templates, with large designated area for storage, and a skidding system to bring XMTs in position for the moonpool elevator.
The improved rig hull design increases the variable deck load capacity significantly. In combination with a lowered setback location design, this allows for transiting to site with fully loaded setback, which in hand improved rig efficiency.
The ISLAND INNOVATOR is a 6th generation, GM4000 WI Enhanced design, 2012 built semi-submersible drilling, well intervention & completion-unit. The rig is currently equipped to operate in water depths from 60m up to 600m (drilling), and 1200m (well intervention and completion riser).
Island Innovator is designed for NCS (Norwegian Continental Shelf), and for world wide harsh environments, and upgraded according to OTG 013 and 014 requirements.
Station keeping is maintained by an 8 line mooring system, or by dynamic position mode maintained by 6 fixed pitch, variable speed thrusters (DP3).View the Island Innovator Rig brochure here
