MAN to Provide Propulsion for GC Rieber’s Seismic Vessel (Norway)

first_imgMAN Diesel & Turbo recently signed a contract for the supply of 8L32/44CR B.2 engines as part of a complete propulsion package to power a seismic vessel ordered by GC Rieber Shipping of Norway.The contract contains an option for an extra vessel. Four of the engines, along with 2 × 2-speed Flender Twin-In/Single-Out reduction gears and MAN Alpha Twin Screw CP propellers in AHT nozzles, will power the vessel. The seismic vessel is graded as Ice Class 1A*, which provides a good basis for operating in Arctic areas.The vessel design is an ST 324 XT from Skipsteknisk of Aalesund, Norway whose hull will be constructed in Poland with outfitting subsequently carried out at the Myklebust shipyard north of Aalesund. The propulsion plant is scheduled for delivery by May 2014 with vessel delivery following in March 2015.Expertise in ice has long been a GC Rieber Shipping trademark with an emphasis on delivering customer solutions for demanding operations in sensitive environments where quality, safety and environmental concerns are crucial. These tough requirements also apply to the propulsion plant and the shipyard’s previous, positive experience with MAN Diesel & Turbo engines was decisive in finalising the propulsion package.Propulsion packageThe four-stroke 8L32/44CR B.2 common-rail engines with a high-powered 600 kW/cylinder will be constructed and tested in Augsburg, Germany – headquarters of MAN Diesel & Turbo. The common-rail B.2 engine is one of the most advanced in the company’s product portfolio, has a second-to-none SFOC, and has gained a solid foothold in the offshore business.The reduction gears from Siemens-Flender are specially designed such that – at constant engine speed (750 rpm) – two different propeller speeds can be selected (155 rpm or 120 rpm), allowing the propellers to have a much wider silent-operation window. The TI/SO gears are also provided with 2 × 2,600 kWe PTOs each.The MAN Alpha VBS1100 Mk5 CP propellers utilise, courtesy of up to six operating modes, the flexible propeller-output speed to operate at the optimum efficiency in all modes. Suppressing cavitation on the propellers is an important design criterion since, especially on the pressure side, the noise deriving from cavitation can disturb seismic sonar readings.The ø4200 CP propellers operate in Alpha High Thrust (AHT) nozzles, which further help to increase propeller performance by offering higher thrust at low vessel speed, and reduce cavitation noise through selection of the optimum nozzle L/D ratio.The Alphatronic 2000 remote-control system facilitates the most favourable propulsion-plant control in all operating modes. A special feature of the new seismic vessel is an ‘ice operation mode’ since the DNV Ice 1A* only applies when one engine is engaged to each propeller shaft. The complete propulsion plant at 100% MCR is classed as fully MCR certified by DNV for operation in areas with no ice.Finally, as part of the overall deal, MAN Diesel & Turbo will provide two years of online service and PrimeServLab (stringent quality control for engine operating fluids) on board in order to obtain valuable performance data for seismic high-load operation.[mappress]Press Release, June 28, 2013; Image: skipsteknisklast_img read more

From Antwerp to Açu

first_imgThe vessel transported a Siemens gas turbine for a thermoelectric power plant developed by Gás Natural Açu (GNA) – a joint venture of BP, Siemens and Prumo, the parent company of Porto do Açu.The gas turbine was delivered by barge from Mülheim, Germany, to the Katoen Natie terminal in Antwerp, where it was subsequently loaded into the hold of the BBC Amethyst, together with other bulky components.Since 2017, Port of Antwerp International, a subsidiary of the Antwerp Port Authority, has been a shareholder of and consultant to the port of Açu, with a goal of promoting trade with the Belgian gateway.portodoacu.com.brwww.portofantwerp.comwww.bbc-chartering.comlast_img read more

CWI to revamp selection policy

first_imgBRIDGETOWN, Barbados (CMC):Cricket West Indies (CWI) is set to revamp its selection policy in an effort to rid the process of “politics or petty emotional situations”, in a move geared towards having the best squad selected for the upcoming ICC World Cup.New president Ricky Skerritt said the selection policy had come under heavy scrutiny ever since he and Vice-President Dr Kishore Shallow assumed the reins of the regional governing body two weeks ago, and it was now hoped that the changes would result in a broadening of the selection pool.“In the last two weeks, one of the most critical points that has been embedded as a selection policy is that if a player can still get selected for the team, they must be considered,” Skerritt told cricket website, Cricbuzz.“There must be no reason for non-consideration other than cricket or medical or physical health. No administrative issues, politics or petty emotional situations must prohibit or prevent players from being considered for selection.”New Cricket West Indies president, Ricky Skerritt.He continued: “The last 10, 11 days since the election, we’ve been bringing in changes in terms of personnel and policies to make sure that we can reach out to everybody who wants to play for West Indies. WIDE SLATE “The people responsible for selecting, managing and leading the squad to the World Cup have been reaching out to players who may be interested, to let them know that the policy has changed and to be clear whether they are available or not, so that when the group gets together next week to make their final decision on the squad, they have as wide a slate to choose from as possible.”Selection politics has remained a perennial issue in West Indies cricket but became a major talking point in recent years as the relationship between senior players and the Dave Cameron-led CWI administration frayed.Darren Sammy was inexplicably axed as captain and dropped from the squad five months after guiding West Indies to the capture of the Twenty20 (T20) World Cup in India three years ago, with many believing the move was as a result of his controversial public criticism of Cameron and CWI’s handling of player issues in the lead-up to the tournament.Similarly, recently retired all-rounder Dwayne Bravo was never picked again in a one-day squad after playing a key role in the contentious, abandoned tour of India in 2014. He was also sacked from the T20 squad in 2016 following the disastrous tour against Pakistan in the United Arab Emirates, which followed the firing of head coach Phil Simmons – a development subsequently criticised by Bravo.last_img read more
