B No 284, B No 262, and B No 264 in 2009 and 2010, which will complete our current construction phase.’ B No 233 is a clean oil, oceans tank barge


measuring 91.4m long, with a 19.50m beam and a depth of 6.40m. T e barge has 10 cargo tanks, with Byron Jackson cargo pumps, driven by John Deere engines. T e barge has accommodations with full galley for four, and is classed ABS, +A1 Oil Tank Barge, Manned Oceans. Bollinger Marine Fabricators (BMF)


delivered the sister ship, B No 231 in July 2007. BMF are also building B No 262 and B No 264, both 60,000bbl OPA’90 tank barges that are scheduled for delivery in 2009 and 2010. Bollinger will also be delivering B No 260, a 60,000bbl OPA’90 tank barge, in the third quarter 2008, and B No 284, an 80,000bbl OPA’90 tank barge, in 2009 from the Bollinger Gretna facility for Bouchard. Ben Bordelon, executive vice president


of Bollinger Shipyards Inc said, ‘Bollinger’s success with new building and repair projects for Bouchard is directly attributed to Bouchard’s confi dence in Bollinger and our skilled workforce. Our dedication to building the best OPA’90 tank barges is refl ected in these units to Bouchard and all of the units we have built for the marine industry.’


New barge order Vosta LMG of T e Netherlands has been awarded a contract for the delivery of a complete engineering and component package for three hopper barges for Van Oord. T e order consists of the design and


engineering of the 10,000m3 hopper barges, including the delivery of the bottom doors, electrical, and hydraulic installations. The hopper barges are fitted with a


hydraulic bottom door system and a special coupling system for the pusher tug. The vessel will be built at COSCO


shipyard Dalian, China. Installation and assembly of all critical components will be under VOSTA LMG supervision. Where possible, components will be supplied by Chinese manufacturers with the assistance of the Vosta LMG offi ce in Zuhai. Vosta LMG will also supervise construction and assembly. T e hopper barges will be available in


60


the fi rst half of 2009 aſt er which they will be transported to Dubai, where they will be used as sand transport barges.


Vuyk gets a handle on loading Vuyk Engineering, Rotterdam, has been involved in the recent development of barge loading with new hydraulics being invested in to make loading and unloading of barges used for dredging easier. T e idea behind the concept is to be able to keep dredging while the dredged spoil is being disposed of. Production improvement will be


achieved through depositing the dredged spoil onto a string of barges, which will shuttle to the dump area. T e dredger will dispose her spoil to a barge that comes alongside it. For relatively accurate transfer of the


dredged material and to reduce the size of the equipment, the vessels need to come as close to each other as possible, therefore fenders are foreseen, as well as a connection between the two ships. Both will allow for limited relative motions between the two vessels without applying excessive loads on either. Vuyk Engineering Rotterdam has been


involved in both the conceptual design and the engineering for the outfi tting of the dredger and barges. T is comprised the design and engineering of loading arms, a hoisting tower installation, and its integration into the ship’s hull. Furthermore,


relative motions between the vessels. T ese are required to engineer the connections between the two barges.


Damen developments Damen Shipyards Bergum has developed two types of barge as their standard; a 2100tonnes and a 3400tonnes deadweight vessel. However, in recent years the increased demand for new tonnage coincided with the upgrading of several designs to bring the currently offered models up to 2500tonnes and 3800tonnes deadweight. Both types are suitable for both gasoil/MDO engines, as well as for engines burning heavy fuel. Recently two ice class vessels were introduced with a carrying capacity of 3700tonnes and 7200tonnes. Both types are currently under construction for delivery in 2008. These new models, named Damen


Combi Freighter 3700 and 7200, meet the requirements of many owners for both ice-strengthened hulls, meeting the latest Rules of the Swedish Finnish Ice Class and the ability to run the main engine on IFO 380, a worldwide available heavy fuel grade. In addition, the Damen Combi Freighter 7200 can have extra equipment added on.


A twin crane of 40tonne safe working the connections from


loading arms to the ship’s dredge line were designed. T e complete mooring system was designed with quick release hooks on the barges and mooring winches on the dredger. The connection and handling system of the ship-to-ship fenders was also part of our scope. One of the vessels is equipped with


hydraulically-operated hinge points in the loading arm to be able to accommodate a range of barge sizes. For one dredger Vuyk Engineering designed the complete installation, whilst, focusing on mooring and barge outfi tting for two others. Apart from engineering the required


changes to the vessel, Vuyk can also perform multi-body motion analyses with the program AQWA for determining


load each has been included for the vessels under construction. Also, a range of coastal tankers was developed which resulted in several newbuildings for UK and Dutch clients in recent years. The design includes state-of-the-art


technology for environmental safe layouts (full double-hull confi guration including the domestic fuel tanks), emission-friendly engines and exhausts, low noise signature accommodation arrangements for crew comfort and “home” coming propulsion systems by using the generators and a power take-in for propulsion. T e series of double-hull oil tankers


include a 2200tonnes, a 3500tonnes and a 5400tonnes model, equipped with deep-well pumps or gear type pumps for owners to choose from. A recently delivered 5400tonnes vessel is trading successfully between the UK ports, the stainless steel pumps are capable of discharging the cargo tanks to a minimum of 10litres of product
