With a threatening typhoon looming, a semisubmersible accommodation unit under construction at Chinese shipbuilder COSCO’s Qidong offshore-focused shipyard saw all six of its thrusters installed in record time.
According to the builder, the thrusters’ installation process was completed in a mere 52 hours, breaking COSCO’s previous record of 72 hours for offshore thruster installation.
The unit, being built for the Mexican buyer Cotemar, was towed to anchorage at 2 a.m. on July 3 after very thorough preparation, and by 11 a.m., the unit was ready for the first thruster to be installed.
Despite “huge and frequent waves” ahead of the imminent typhoon Chan-hom, COSCO said the installation team was able to install all six thrusters by 3 p.m. on July 5, smashing the 72-hour record set on its sister unit.
Following the thrusters’ installation was testing and verification of the unit’s service speed, DP3 dynamic positioning ... [More]
Rolls-Royce said today in a press announcement that it will supply water jets for three wind farm support vessels, (one 24-meter and two 26-meter aluminum catamarans) to be built by South Boats IOW for the offshore wind transfer vessel operator Seacat Services.Rolls-Royce labeled the contract as “one of the biggest orders made for wind farm workboats,” and all three newbuilds will feature two Rolls-Royce 56A3 stainless steel water jets as well as Rolls-Royce’s new compact control system tailored to suit owners’ requirements and reduce build/installation times.The new wind farm workboats will include MTU 12V 2000 engines which will power the catamarans to speeds of up to 30 knots. Once in operation, the catamarans will be used for people and cargo transfers to the growing number of offshore wind farms around the coast of Europe.When factoring the water jets’ properties into the vessels’ overall design, the propulsion system contributes a safety elemen...

American shipbuilders rarely deliver a ship that’s built for heavy duty offshore rig supply work that also turns heads, but a recent delivery from Houma, Louisiana-based New Generation Shipbuilding is already doing just that with the new 171-ft ‘Mr. Ernie’.

This striking vessel was built for same-name owner Ernie Vicknair and his partner Joe Gregory for rig support work in the Gulf of Mexico. According to Cummins Hotips, credit for the distinctive super-structure design goes to Incat-Crowther, although the design and engineering support team also included Parfait Maritime; Mino Marine LLC; and Farrell & Norton Naval Architects. The outcome of their collective effort contradicts the old saw that if you want to kill any idea in the world set a committee to work on it.Propulsion powerA pair of Cummins K38M Tier 2 diesels deliver a total of 2000 HP through Twin Disc MGX-5321 gears to 72x65-inch Bird Joh...

DP3 is a new offshore vessel positioning technology standard set by IMO that will enable a couple of new Farstad offshore vessels on the stocks in Norway to work safely in the most demanding and potentially dangerous situations using systems equipment provided by Rolls Royce.Basically, to maintain an accurate position determined mainly by satellite navigation system (anchoring is not in itself precise enough) an offshore vessel needs to be equipped with propulsors and thrusters controlled automatically by a dynamic positioning (DP) system in such a way as to oppose the resultant force of wind, waves, tides and currents.

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]
Fleet grows up to ten vessels – On duty in the Gulf of Mexico – “Sea Axe Bow” reduces fuel consumption.
Dutch based Damen Shipyard will deliver two new builds to Mexico.
The 50 m crew boats, designed with the Damen patented Sea Axe bow, are currently under construction at Damen yards in Vietnam. Delivery for the first vessel is expected late November 2013, whereas the second vessel will be handed over to Naviera Integral mid-January 2014. The crew suppliers are the ninth and tenth of this type Damen has delivered to its long-time Mexican client.The ship type, in the form of Naviera Integral’s ‘Doña Angela Maria T’, was awarded ‘Ship of the Year’ in 2009, at the Dutch Maritime Awards Gala. The main reasons were the proven success of the Sea Axe bow concept, the resulting improved seakeeping in heavy weather (-70% slamming), the Wide Operating Speed Range engines in combination with fixed propellers (allowing for more thrust an...

A hi-speed offshore crew transfer catamaran is under construction in the Incat Tasmania shipyard whose speed and passenger comfort, designers Incat Crowther say, will make it more cost-effective for transfers of crew and cargo supply operations to offshore platforms than a helicopter. A bold claim and worth looking at.
