CORIOLIS AB has been appointed responsible for design, construction and inspection of the innovative wave energy converter “WaveEL”. The customer, Waves4Power AB, has been in business since early 1980’s in converting the energy from ocean waves into absolutely green electrical energy. The point absorber (buoy) is now successfully moored off the coastline of the Norwegian west-coast and has started to produce electricity.
The buoy is 8.0m in diameter and more than 40m high with an operational displacement of more than 100 metric tonnes.
CORIOLIS AB has also made all relevant calculations required for the marine operation when the buoy was lifted, launched and moored.
Turkish shipyard Özata has built a series of high speed, light craft passenger catamarans for the municipality of Izmir. Newbuilding numbers are 28, 29, 30, 31 & 32 and they are built in vacuum infused carbon/sandwich.
The vessels are certified acc. to the HSC2000-Code and are built in accordance with DNV’s HSLC-rules. They catamarans have a passenger capacity of 426 persons. Length x Beam is 38.9m x 11.6m and Speed (operational) is 20 knots.
The ferry boats will serve the public transportation in bay of Izmir, Turkey.
CORIOLIS AB has been engaged to produce the stability documentation, intact- as well as damaged stability calculations.
The two river shuttles, “Älveli” and “Älvfrida” are now delivered to Västtrafik. The ferries will be used for the river-crossing in the city centre of Gothenburg. Each vessel has a capacity of 298 passengers and 80 bicycles and is served by two crew members.
Main dimensions are 33.0m x 8.5m and the operational speed is approx. 8 knots.
CORIOLIS AB has acted as Västtrafik’s naval architect and owner’s representative during the procurement and newbuilding process.
Norrlands Sjöentreprenader AB, Härnösand-Sweden, upgrades its tug boat ”Max” by changing out the complete propulsion line (enginegearboxshaftpropeller) in order to obtain an increased bollard pull. ”Max” is also used as an ice-breaker where the improved bollard pull will increase the vessel’s performance.In order to avoid over-heating problems due to ice-plugged sea water inlets the vessel will be equipped with a new box-cooling system.CORIOLIS AB has been engaged to design the changes and reinforcements of the hull induced by the retrofit. In addition, all technical calculations such as strength-, stability- and thermal calculations, will be carried out by CORIOLIS.
Mors- & Thy Færgefart A/S has engaged CORIOLIS AB, together with Niels Hjørnet Yacht Design och Danish Yachts, to design a conceptual ferry for operation in Næssund, Limfjorden, Denmark. The energy consumption will be minimal and the propulsion will be fully electric using plug-in technology and energy storage onboard.The capacities will be 98 passengers and twelve private cars. It will also be possible to load one (1) truck (32T). One-leg journey is 1000 m which will take approx. 5 minutes using 8 knots speed.The vessel’s lightweight will be minimized using carbon fibre/sandwich construction (CFRP). In addition, all ship’s systems will be designed in a ”minmalistic” way in order to save weight.Due attention has been given to the hydrodynamic performance of the hull.Energy storage will be by means of batteries or supercapacacitors.
Municipality of Gothenburg has, via Västtrafik, decided to order two double-ended shuttle ferries for the river-crossing in the city centre of Gothenburg. The ferries will have the capacity to carry 300 passengers and 80 bicycles. Main dimensions will be 30m x 8m and the operational speed will be approx. 8 knots.CORIOLIS has been engaged as Västtrafik’s naval architect during the procurement process and to represent Västtrafik at Yard during the newbuilding process.
CORIOLIS AB has been appointed as design-leader for a new type of ferryboat, built of lightweight materials and with extremely low energy consumption. The ferryboat will operate in domestic waters, Area D, in accordance with EC’s Passengerboat directive.The project is cooperation between Swedish and Danish parties. Designers, yards and authorities participate to solve those obstacles which appear when materials of novel design are used in shipbuilding. A Danish shipowner has contributed with data from an existing ship, thus establishing a “reference ferry”. The objectives will be to design a low-consuming, lightweight ferryboat which can carry out the same transportation work as the “reference ferry” but to a substantially lower life cycle cost.Read more about the project at : www.eco-island.dk
Passenger ship m/s “Birger Jarl” was built at Finnboda Shipyard, Stockholm, in 1953 as a SOLAS vessel (SOLAS-48). Following the fire accident at “Scandinavian Star” in 1992, rules regarding fire safety were changed and these stricter rules apply retro-actively for “Birger Jarl”.CORIOLIS AB, together with SP-Borås, have been appointed to suggest an action plan following a so called Regulation 17-analysis. (SOLAS Ch.II-2, Reg17, Alternative design).Additional fire protection measures are studied and evaluated in a risk-analysis, performed acc. to guidelines developed by IMO. The objectives are to maintain major parts of the beautiful interior decoration and instead introduce alternative safety measures to reach a level of equivalent safety.The retrofit will be done at Stockholm Repairyard.
Upon request from Norrlands Sjöentreprenader AB, Härnösand-Sweden, CORIOLIS AB has outlined a procedure for ”capsizing” two barges (180 degrees) to get them upside-down. The barges, owned by SKANSKA measure 45m x 10m and the displacement (each barge) is 166T.The purpose being to find a simple and cost-effective way to change out the bottom shell plating without dry-docking the barges.Using Archimedes principle, free surface effect and some high capacitiy pumps the ”rotation” was done in June, 2011. CORIOLIS AB participated in the roll as ”supervisor in charge of the procedure”.
ELBE’s Fiske & Marin AB has decided to upgrade its fishing tour vessel ”Clipper af Varberg” in accordance with EC’s passenger boat directive, Area B.The vessel operates on the westcoast of Sweden from Malmö to Strömstad and has capacity to carry 45 passengers.”Clipper” is built of wood (oak) in 1967 at Fredrikssund shipyard, Denmark. Following retrofit, she will comply with the Directive’s rules for damaged stability. In addition to installing watertight bulkheads, also new fire main system and bilge water system will be installed.CORIOLIS AB has been engaged to design the watertight bulkheads and the shipborne systems. All related calculations, including the damaged stability calculations, will be carried out by CORIOLIS.
Marinvest KB has acquired 30’000 DWT Chemical tanker “Mariline”, built in Japan 1996. In the company’s ambition for environmental friendly and economical solutions, the existing inert gas scrubber will be changed out in favor of a new N2-generator plant.For this purpose, an approx. 400 m3 extension to the existing superstructure must be designed and constructed.The job will be carried out at Chengxi Shipyard, China.On behalf of Marinvest KB, Coriolis AB have produced steel structure drawings and machinery systems drawings and had it approved by Class (DNV).
