Fourth vessel in the HOCHTIEF fleet / Jack-up vessel enables efficient offshore installation / HOCHTIEF makes important contribution to energy turnaround
The jack-up vessel was developed especially for construction and servicing of offshore wind farms and oil and gas plants at sea. Thanks to its large deck surface, its high deck cargo and the powerful 1,200-ton crane, the ship is ideal for the safe and fast assembly of foundations and components for wind farms in the North and Baltic Sea. With its 90-metre-long legs the jack-up vessel can operate in waters up to 50 metres deep and install latest-generation wind turbines of all dimensions.
HOCHTIEF has already chartered the jack-up vessel to a client even before completion, it will be used for blade installation at the North Sea wind farm Global Tech I from December 2013. VIDAR - just like its sister jack-up vessels THOR and INNOVATION - was built at the Crist shipyard in Poland. INNOVATION and THOR are currently being used for the i... [More]
Incat Crowther, Australia, has announced a first of type 70m Catamaran Fast Crew Boat (FCB), compliant with IMO HSC code and complete with a crew transfer system consisting of dynamic positioning equipment class (DP2) coupled with a stabilized access platform. Construction of the vessel has commenced at the shipbuilder Incat Tasmania, with delivery scheduled for September 2014. The new crew transfer vessels will be delivered to Caspian Marine Services Ltd (CMS) in Baku, Azerbaijan.
The vessel will operate as a fast crew transfer vessel for 150 offshore workers to multiple offshore installations.

The vessel is designed to operate in sea conditions of 40 knot wind and seas of 3m significant wave height.
The high speed of the 70m FCB allows operat... [More]
DNV has gathered before and after operational-performance data which indicate that redesigning the bulbous bow of slow-steaming container ships can produce fuel savings of 5 per cent or above. These ‘nose jobs’ can have a payback time of less than a year.
Hyundai Merchant Marine (HMM) operates a series of 8,600 TEU container vessels which were designed and built for high speed. These vessels are actually able to operate at 27 knots. However, today the vessels are “slow steaming”, operating in the range of 15 to 18 knots. At these speeds, the existing bulb is not efficient.
In order to quantify the possible savings potential, DNV carried out a comprehensive study to develop a new bulbous bow shape optimised for the expected trading conditions. A cost-benefit assessment was conducted based on the estimated savings and this created the basis for HMM to go ahead with a conversion.
Based on input from DNV, Daewoo Ship Engineering Company (DSEC) carried out the struc... [More]
Ulstein Verft delivered ‘Blue Thunder’, the fourth of six medium-sized platform supply vessels of the PX121 design from ULSTEIN® mid of March to Blue Ship Invest. Owned by Blue Ship Invest, a wholly-owned company in Ulstein Group, the platform supply vessel (PSV) is commercially and technically under the management of Atlantic Offshore. ‘Blue Thunder’ will enter a 4-month contract with Statoil, with 4 monthly options. “We have received good feedback from the operators on her three sister vessels, and we are very pleased that this ship also enters into a contract for work in the North Sea,” says Gunvor Ulstein, CEO of Ulstein Group and Managing Director of Ulstein Shipping, adding that the remaining two vessels will be delivered later this year and all six vessels are for sale.In the North Sea, PSVs of the PX121 designs are considered medium-sized. The vessels with this design have an optimal combination of fuel-efficiency and deadweight. They hav... [More]
Det Norske Veritas (DNV), a leading classification society, and Process Systems Enterprise Ltd. (PSE), a global provider of advanced process modelling technology, recently have released the results of the Maritime CCS (carbon capture and storage) research and development project.
The project has successfully developed a concept design for on-board chemical CO2 capture. The system consists of a chemical absorption plant that separates CO2 from flue gases, a liquefaction unit where the captured CO2 is compressed and condensed using a refrigerant and two storage tanks where the liquid CO2 product is temporarily stored until discharge into transmission and storage infrastructures at the next suitable port. The results show that the concept is technically feasible and capable of reducing ship CO2 emissions by up to 65%. For a VLCC tanker, this could correspond to capturing more than 70,000 tonnes of CO2 per year, transforming them from emissions to a tradable product.

Gesa Assheuer, nine-year old daughter of WindMW GmbH CEO Jens Assheuer named the companies new Swath-Offshore Tender GESA by the end of November 2012 in the port of Bremerhaven.
Build by the Norwegian Maloy Verfts AS under the yard number 16, the completely out of GfK made ship with its project designation S-Cat 29, is classified by the DNV (Det Norske Veritas) and can carry 24 passengers. It runs under the flag of Cyprus. The ships particulars are of 29,5 m length and 10,6 m width. According to WindMW the total costs have been 9 million Euro. Two main engines of MTU series 10V2000M72 deliver 900 kW each and bring the ship up to 25 knots. Additionally two bow and two stern thrusters of type Sleipner SH1200 are installed. Maximum deck load is of 4 ton. A 1.6 ton crane is mounted on the aft deck. The draft of the ship with Swath-characteristics is normally of 1.6 m but at heavy sea conditions draft can be extended up to 2,2 m. With this better rough sea behaviour is achieved. GESA is ru...

The world fleet will be greener, leaner and meaner in the next eight years according to DNV’s Research and Innovation Unit in their just published ‘Technology Outlook 2020’ as they follow the example of the poet Tennyson – “For I dipt into the future, far as human eye could see, saw the vision of the world, and all the wonder that would be.” So too, the DNV team made many correct predictions in its last 2008 ‘Outlook’ (although they admit surprise that the wind energy sector developed so rapidly) which gives added weight to their latest analysis.

The 200,000 GT vessels have an LOA of 1,187.7 ft, and deadweight of 400,000 t. In total, 35 ships of this class are being built by four different shipyards, two in China and two in South Korea. There are slight differences in the ship dimension according to the builder and preferences in engine supplier and type. The vessels produce very low emissions on a cargo ton per mile basis and consequently the Valemax Class is one of the most efficient dry bulk carriers in service 35 per cent reduced emissions. [More]
Norwegian ship owner Myklebusthaug Management has placed an order with ABB for the supply of a direct current (DC) power grid on board a new 5,000 ton multi-purpose oil field supply and construction vessel of 305 ft, due for delivery in the first quarter of 2013. Using a DC grid offers several advantages including lower installed power thereby reducing fuel bills while producing up to 20 per cent less emissions. The reduction of the space and a weight of transformers leaves more available volume for a larger payload. The total weight saving of electrical equipment alone can be as high as 30 per cent. Many higher efficiency energy source options coming in the future such as solar panels, fuel cells, batteries etc., will be easy to connect and integrate into an onboard DC grid. Depending on the ship’s usage profile, ABB claims that up to 20% fuel savings can be achieved using a DC grid.. [More]
