The X-gas Project is a sequence of modern and unconventional, medium-capacity Liquified Gas / Gas bunkering tankers designed by KNUD E. HANSEN. The flagship design of the challenge is a 126.5 metre vessel with a complete cargo capability of 9,000 cubic metres, cut up between two Type C tanks. The platform, nevertheless, is very customizable and could be tailor-made to accommodate a variety of tank capacities, in addition to numerous containment programs together with membrane tanks.
The most unusual characteristic of the X-gas platform is a low-profile, ahead deck home. This permits the vessel to soundly method and pull alongside cruise ships with low-hanging lifeboats. This additionally minimizes the necessity for ballast throughout cargo switch, thereby reducing operational prices. Lastly, the ahead deck home permits for bigger cargo tanks with out impeding bridge visibility.
For improved maneuvering and security, the design options two propulsion thrusters aft and two bow thrusters, in addition to an autodocking system for alongside mooring.
The design contains a novel and intensely fuel-efficient diesel electrical energy and propulsion plant consisting of some of the gas environment friendly dual-fuel Four-stroke engines out there. Integrated with the propulsion plant is an Energy Storage System (ESS) with a lithium-ion battery financial institution that permits for engine load optimization with lowered methane slip. The batteries additionally present the entire energy required throughout cargo switch, leading to no emissions or exhaust in approach of the ship being bunkered, an particularly necessary characteristic for passenger vessels.
Boil-off fuel from the cargo tanks is captured and consumed within the dual-fuel engines and the vitality surplus generated could be saved within the batteries. Waste warmth from the engine cooling water is transformed to electrical and thermal energy by means of various ORC (Organic Rankine Cycle) waste warmth models. As a novel method, wasted vitality captured throughout operation could be saved in accumulators and launched as required to drive absorption chiller and cut back load onboard. This method boosts vitality effectivity to a really excessive stage.
Another distinctive characteristic of the design is an aft ‘vitality bay’ that permits the vessel to offer containers loaded with gas or saved electrical energy to a receiving vessel. It additionally permits the vessel to offer absolutely charged battery banks to distant places ashore, the place present infrastructure doesn’t enable enough energy to be offered.
Through the X-gas Project, KNUD E. HANSEN has harnessed its huge expertise and popularity for designing groundbreaking, vitality environment friendly ships to create a brand new platform that may help cleaner vitality for generations to come back. KNUD E. HANSEN is already increasing the X-gas platform to accommodate zero emission fuels similar to liquid and compressed hydrogen to satisfy the rising demand on this sector.
KNUD E. HANSEN is a Danish-based, main impartial consultancy that has been offering a complete vary of design, engineering and challenge administration companies to shipyards and ship house owners world wide since 1937.
