Status of the Equipment

Seafloor Production Tools (SPTs)

In January 2016, the Company took delivery of the three Seafloor Production Tools (SPTs) from SMD. The SPTs were shipped to Oman. The Company is currently reviewing various wet testing options in Oman and PNG. The  wet testing  is designed to provide a submerged demonstration of the fully assembled SPTs and will involve submerged testing of:

  1. Control systems operations and feedback
  2. Hydraulic functions
  3. Collection system functions
  4. Survey and visualization systems


The three umbilical winches that store and manage the power and control umbilicals were designed, procured and assembled at SMD. In March 2015 the Company announced that the umbilical winches for the three SPTs had successfully completed FAT. The umbilical cables have since been installed onto the umbilical winches. They will be shipped to the shipyard for integration on to the vessel at a future date.

Launch and Recovery System (LARS)

The Launch and Recovery System (LARS) which will be used to lift the tools in and out of the water, is comprised of A frames, lift winches, hydraulic power units, electric power units and deck control cabins. The LARS is currently in storage and will be sent to the shipyard at a future date.

Riser and Lifting System (RALS)

GE Oil and Gas, the primary contractor for the Riser and Lifting System manufacture, has begun retrieval and inspection of the components that were previously in storage or in mid assembly when the contracts were terminated in 2012. The manufacture of components such as the derrick and riser handling systems, surface seawater pumps, pull in skids, riser transfer hoses and other ancillary equipment is to be resumed with delivery dates dictated by the shipyard requirements for the PSV. These components are to be integrated onto the PSV during vessel manufacture.

The Subsea Slurry Lift Pump (SSLP) recommenced assembly in Q3, 2015 and in February 2016 commenced Factory Acceptance Testing.

Welding of the connectors for the riser pipe commenced in January 2015. Nautilus anticipates taking delivery of the Riser and the surface seawater pumps at a later date. Work on the derrick and riser handling systems remains ongoing. Delivery of the riser transfer hoses is due to occur in Q4 2017.

Production Support Vessel (PSV)

An agreement for the charter of a PSV to be first deployed at the Solwara 1 Project was awarded to Marine Assets Corporation (MAC), a marine solutions company based in Dubai which specialises in the delivery of new build support vessels for the offshore industry. MAC, will own and provide the marine management of the PSV.

Fujian Mawei Shipbuilding Ltd. (FMSL), based in Fujian province in south-eastern China has been contracted by MAC, to design and construct the PSV in accordance with Nautilus’ specifications.

In September 2015 the first steel for the PSV was cut. In June 2016 keel laying for the PSV occured.

Main contracts awarded by FMSL to date for the PSV:
 

Package To Whom Comments
Engines & thrusters packages Rolls Royce Marine, Norway The order secures the main engines, azimuth and tunnel thrusters.
Cargo handling equipment Bedeschi SPA,  Italy The cargo handling equipment will be used to transfer the dewatered mined material into four storage holds in the PSV and then to recover the material from the storage holds where it will be transferred directly on to Handimax vessels for transhipment to our processing partner in China, Tongling Nonferrrous Metals Group Company, Limited.
