IHC Merwede has been awarded the contract for the design, construction and delivery of a 23,684kW self-propelled cutter suction dredger (CSD) from Royal Boskalis Westminster. and the pump ashore capacity is of 15,600 kW. The new CSD is a replacement investment. The 152m-long and 28m-wide dredging vessel will be one of the largest CSDs of its kind in the world, IHC said. The total investment amounts to around EUR 170 million and construction of the vessel is expected to take more than three years.
Much attention has been paid to the design in terms of safety, the environment and increased operational workability. A particular feature of the vessel, which has a maximum dredging depth of 35m, is the widening of the aft ship in order to reduce the draught. It offers accommodation for 45 crew member.This Cutter Suction Dredger (CSD) is a suction dredger equipped with a rotating cutterhead. The CSD is positioned on spuds and anchor wires during dredging operations. A CSD is ... [More]
After transfer from Southampton service as a hotel vessel at the “Super Bowl” in New York – First cruises in the Caribbean
During a ceremony at the beginning of January 2014 in Bremerhaven, Norwegian Cruise Line took delivery of the 145,655 gross ton cruise ship Norwegian Getaway from MEYER WERFT after a building period of only 15 months. The ship, the second of two Breakaway Class ships, is being delivered just nine months after the launch of sister-ship Norwegian Breakaway. Following delivery today, the ship is sailing to Rotterdam for the start of inaugural festivities which will continue in Southampton before the ship departs for her transatlantic cruise to New York. The ship will be christened in Miami on February 7.The cruise liner starts the first transfer from Southampton to New York with around 1.500 crew members from over 60 nations. In New York the vessel will act as a hotel ship for the super event “Super bowl”. After the christening ceremony i... [More]
NYK to Build Japan's First Natural Gas-Fueled TugNYK will build a tugboat featuring a dual fuel engine that can be powered by either Natural Gas, which will be stored as LNG, or heavy fuel oil. Other than LNG carriers, this tugboat will be the first building in Japan of a Natural Gas-fueled vessel.
NYK has enhanced its initiatives to mitigate environmental loads through the practical realization of environment-responsive technologies such as solar-powered systems and air-lubrication systems. In 2011, NYK established a team in the company’s Fuel Group to research next-generation fuel alternatives to heavy oil, and looked into building a Natural Gas-fueled vessel with the cooperation of Nippon Kaiji Kyokai and others, based on the results of a survey conducted by the Japan Railway Construction, Transport and Technology Agency. Natural Gas received attention as a possible alternative to heavy oil because NG does not emit any SOX and produces far less CO2 and NOX compared to heavy ... [More]
Condition Monitoring Technologies (CMT) GmbH, Germany, has developed a flexible thruster monitor for the marine and offshore industry whose aim is to predict failures at the earliest possible stage, thus avoiding costly unplanned repairs, adjustments and downtimes, the German company said. In the modern shipping and offshore industry, unplanned thruster repairs and adjustments - both in dry dock and in situ - always lead to enormous costs, loss of productivity and decreased competitiveness. CMT has developed a unique flexible thruster monitor that ensures that any damage, wear or necessary adjustments are identified immediately, allowing preventative action to be taken. The CMT thruster monitor system is unique in that it provides real-time feedback on a whole range of both oil and vibration parameters, providing unparalleled comprehensive control and security. The fully automated system is said to be ideal for both new- buildings and retrofits as it can be easily combined with any exi... [More]
If power is lost to a DPS-controlled drill-ship’s thrusters there is a risk that the rig will drift off its position, which can potentially give rise to huge impacts and the risk of damage to the subsea equipment (Blow Out Preventer (BOP), Riser, and associated equipment). Along with such an unfortunate occurance also will come significant financial impacts; the cost of repairs, new equipment and lost day rates. Clearly, in the event of a power loss, the speed of engine re-start is of critical important.

Since 2011 Maersk Drilling has invested USD 4.5 billion in seven new drilling units; three ultra harsh environment jack-ups at Keppel FELS in Singapore and four ultra deepwater drill-ships at Samsung Heavy Industries in South Korea. In the design of the drill-ships’ electrical propulsion system, Maersk say that their engineers, set the engine emergency start-up time bar higher, looking for a decrease in the usual ... [More]
Wärtsilä introduces a new series of both steerable and transverse thrusters that will further develop the current portfolio. The new Wärtsilä Steerable Thruster series (WST) is being introduced to replace the company’s Modular Thruster and Compact Thruster series, while the new Wärtsilä Transverse Thruster series (WTT) is replacing the current range of transverse thrusters. The new products have been developed in response to changing market demands, requiring competitive thruster products which are more efficient and cover a wider power range.
The latest insights in thruster design were implemented using state-of-the-art numerical simulation tools. The first product to enter the pilot phase is a 4500 kW under water (de)-mountable steerable thruster, the WST-45-U, which began its pilot phase in summer 2013. Two more products, the WST-14 and the WTT-11, are scheduled to begin their pilot phase before the end of this year. Wärtsilä will contin... [More]
Propulsion pod pioneers ABB have won an order worth around US$25-million to supply its marine propulsion system, Azipod, and complete electric power plants for two new rescue and salvage icebreakers that are under construction at Nordic Yards GmbH in Germany.

The original idea for the Azipod (Azimuthing Podded Drive) system was conceived a couple of decades ago in response to the Finnish Maritime Administration’s quest for ways to improve its icebreaker operations. Icebreakers must be capable of manoeuvring in such a way that they can break out of an ice channel in any direction in order to assist merchant ships using that channel. Investigations showed that a propulsion motor which could direct the thrust in any direction would be the ideal solution to this problem. The Azipod drive system that was subsequently developed provided the answer with its podded electric propulsion unit, freely steerable through 360 degr... [More]
Damen Shipyards Galati has delivered the ‘World Diamond’, the first of six Platform Supply Vessels (PSV) for Norwegian offshore owner World Wide Supply, built to an entirely new Damen design. The World Diamond was christened by godmother Her Royal Highness Crown Princess Margarita of Romania on June 28th, in a yard ceremony attended by 150 guests.
“Delivery of this first PSV 3300 E3 represents a new era in Damen’s continuing offshore supply vessel story,” said Arnout Damen. “This has been a truly collaborative project, with Damen drawing on expertise from within the group and the client and also from partners among leading research institutes and subcontractors to deliver a first in class vessel designed, built and equipped to European standards for a world class customer.”
Steinar Kulen, representing owner WWS, said: “The cooperation on World Diamond’s design has ensured the delivery of a mid-size PSV capable of worldwide operation... [More]
