Nautilus Minerals Inc. announces that its Board members were in attendance at the shipyard of Fujian Mawei Shipbuilding Ltd to see the progress that has been made on its Production Support Vessel (PSV). The PSV is to be chartered by Nautilus and its PNG partner, Eda Kopa (Solwara) Limited, from Marine Assets Corporation. It will serve as the base for its seafloor operations planned at the Solwara 1 Project, in the Bismarck Sea of Papua New Guinea. Geoff Loudon, Nautilus’ Chairman, commented, “It is very rewarding for me and my fellow Board members to be here today to meet the shipbuilders and see the impressive construction progress being made on the PSV. The shipyard 3D modelling for production drawings continues with the yard having already released 90 blocks (out of total 305) for steel-cutting and assembly has commenced on 21 blocks. To date over 10% of the total steel cut has been completed which includes the cutting of 8 full blocks. This is amazing work that has been achieved and I look forward to December 2017 when we expect to take delivery of the vessel to enable us to commence our seafloor operations in Q1 2018.” Source: Nautilus Minerals

November 2014 saw the signing of a contract between Nautilus Minerals Inc. (TSX:NUS, OTCQX: NUSMF) and Marine Assets Corporation (MAC) for the lump sum turnkey construction with a five year charter on delivery for a large offshore construction vessel to be utilized for the first world wide sub sea mining operations on the Solwra 1 JV project.

The vessel will be built at Fujian Mawei Shipbuilding China's oldest shipyard with a proud, 150 year heritage.

Mawei has kept in step with advancing technology, and with the full completion of their new SY in 2017, will possess Dry Dock facilities for vessels in excess of 270m LOA, the dock being 82m wide by 280m long, being spanned by a 700t gantry crane. Mawei are no strangers to high tech DPS-2/3 vessels having already delivered over 25 for MAC alone, which include MAC’s unique design Compact Semi Sub (CSS) Accommodation Vessels.

Current progress on the vessel which is 227m long by 40m wide with installed power of 30 Mw. Design is on-going with Sea-tech Solutions, Singapore, who are in liaison with ABS. as the chosen classification society.

High-level technical meetings have been held with prospective vendors for delivery of the Diesel Electric Power Distribution System, and an order is expected to be placed in the coming weeks. The Engines and Thruster package has been awarded to Rolls Royce, who will deliver the 6 x 5000Kw main engines and 3 x 3000Kw azimuth stern thrusters, along with 2 x 3500Kw Drop Down azimuth bow thrusters and 2 x 2000Kw tunnel thrusters.

Discussions are on-going with other vendors for procurement of DP system – Knuckle Boom cranes and all the other ancillary equipment required for a vessel of this level of sophistication. Both MAC and Nautilus are happy with progress to date, and pleased to report the 36 month build programme is on schedule.


Marine Assets Corporation is very pleased to announce the successful launch by the undocking of our 4th Compact SemiSub (CSS) which will be named Themis, following on from the Olympia and Venus.

MMC 887

The first in class 60m MAC/MAWEI in-house designed MPSV sails for sea trials. The vessel is the result of a market study carried out by Marine Assets Corporation and Fujian Mawei SY, The aim was to create a compact cost effective Multi Purpose Supply Vessel, which could be used in a variety of roles to support offshore operations. Dimensions of 59.6m LOA x 15.2m Beam, with 5000 BHP driving the 2 Azimuth 360 deg stern thrusters and 2 x 450 kW bow thrusters, all controlled by DPS-2 Having a dwt of 1500t @ design draft of 4.8m, she can increase dwt to 1750 @ 5m draft. She can carry 700t on a deck which is already pre stiffened and ready to receive unto a 50t marine pedestal crane. With under deck capacities of 532 M/3 Fuel - 970 M/3 of fresh / drill water - 180 M\3 dry bulk - 390 M\3 mud, and supporting 50 POB. with installed Fi Fi class 1 and a 15 man FRC, she truly lives up to her expectations of a multi roll support vessel. The first in class is already agreed sold on delivery to a ME company, with the second expected to follow her by Q4 2014. 2 more sisters are under construction for delivery Q3 2015. MAC is also developing a Garbage Converter Vessel based on this design, which will have the ability to receive full rubbish skips on deck, and transfer below deck for processing raw garbage into inert material with a 70% volume reduction and a 30% weight reduction. The Garbage processing below deck, is based on the Italian OMPECO designed Garbage Converter technology. Further details expected to be released by Sept 2014.

Marine Asset Corporation (MAC) announces the recent signing of new build contract for the construction of a 500 man Compact Semi Sub Accommodation Vessel - CSS ACCOMODATOR. Marine Asset Corporation (MAC), the company established to hold the share interest in the CSS design concept previously held by Minnow Marine Projects Limited (MMPL)- a company sold to the GMMOS Group in the UAE during Dec 2009. When MMPL was sold, the new owners were keen to focus on their core businesses of AHTS’s, PSV’s and crew boats. Hence MMPL’s investment in the CSS did not fit in with the business plan of the new owners and this necessitated the creation of a new company, to hold the already substantial interest and take the investment forward to the next phase. The CSS Concept has taken 5 years to get to today’s position; from the original concept sketched on A4 paper, to the MODU coded design of today which will change the way the offshore industry works. MAC is pleased to advise the contract for construction has been signed and became effective as of the 3rd May 2010, with a projected delivery of December 2012.

MAC announces signing

Based on the same hull format as the already under construction CSS ACCOMMODATOR a 500 man Semisubmersible Offshore Accommodation vessel. Using the same Hull form, Diesel Electric Power, Propulsion and DPS-3 systems, MAC has in conjunction with our designer STX, adapted the top sides to enable the 24/7 support of offshore renewable energy installations. Based on the model tested hull form which enables a very stable platform from which to operate, MAC will install 100 single room cabins for passengers and 45 for crew and hotel services, all designed to the latest International Labor Organization guidelines, with en suit, internet and flat screen TV in every room. This 5 start Flotel will offer the latest in offshore luxury for the harsh and extreme environments expected to be encountered for the round 3 next phase of the renewable development. The CSS SEEBREEZE will also have installed a crane between 150t – 300t depending on client needs, a telescopic gangway to enable safe transfer of personnel in adverse weather, and carry between 2 to 4 infield utility vessels on the main deck for transport of small crews from the mothership to individual turbines.
