Project Forward Initiative Cuts CO2 Emissions
The Project Forward initiative led by Athens-Based Arista Shipping, with Wärtsilä as one of the participants, demonstrates that with LNG as fuel, an advanced hull design, and highly efficient propulsion machinery, it will be possible to meet the IMO’s target for a 40 percent reduction in carbon intensity by 2030.Model tests of the Project’s concept vessel indicate that the Energy Efficiency Design Index (EEDI) is well below the currently most stringent Phase III level. The EEDI reflects the CO2 emissions per transport work and is a measure of carbon intensity.
New Thruster Solutions Developed for Arctic Shipping
A team of European marine research institutes and companies have developed creative technologies for thruster solutions that are specifically engineered for ships operating in the Arctic.With the new solutions created under the three-year ArTEco project led by Finland's VTT and Wärtsilä, thruster lifetimes can be increased, their maintenance need can be decreased and their reliability improved, particularly in extreme conditions, the project partners said.While at sea, a ship must overcome tough resistance as it displaces water masses from its path.
Underwater Maintenance Operations: Big and Small
Hydrex frequently performs large, complex projects across the globe, but the company says its smaller projects are equally essential. Daily, its divers conduct smaller maintenance operations including installation or replacement of anodes, blankings, replacement of transducers, propeller cleanings and all types of inspections.InspectionsBuilding upon conventional technical skills and know-how while also taking advantage of the latest technology, Hydrex offers a unique hull monitoring service.
HydroComp Upgrades PropCad Premium Feature Set
The latest release of HydroComp's PropCad 2018 Premium Edition includes a new utility to simplify the extraction of propeller features from full 3D CAD files, drastically reducing the time and effort needed to recreate an existing propeller or product model.HydroComp, a Durham, N.H. based maritime software and consultancy services provider, released the new utility as part of the PropCad Premium feature set. The Import CAD File utility provides a way to reverse the propeller design process, allowing for the rapid extraction of propeller design data from 3D geometries.
HHLA Transports Ship Propeller for Hyundai Supreme
Hamburger Hafen und Logistik AG (HHLA) loaded the biggest ship propeller in the world onto a vessel. The “HHLA IV” floating crane brought the gigantic 110-tonne object to the port of Waltershof, where it was hoisted onto the “Hyundai Supreme” container ship.It was the most powerful ship propeller to have ever been lifted by the hook of a HHLA floating crane. Although HHLA regularly loads the specialised products of Mecklenburger Metallguss GmbH (MMG) onto ships in Hamburg, the latest propeller…
Lomar's Super-Eco Boxships Mark Breakthrough for Thordon Bearings
Delaware Trader, the first of two 2,700TEU newbuild containerships that China’s Guangzhou Wenchong Shipyard is delivering to Lomar Shipping this year, has been fitted with a seawater lubricated propeller shaft bearing system from Thordon Bearings.The vessel represents another breakthrough for Thordon Bearings’ COMPAC seawater lubricated propeller shaft bearing system in the European-owned containership segment.London-headquartered Lomar Shipping, a privately-owned ship owning and management company…
TORM to Feature Scrubbers in Newbuildings
Danish shipping company TORM is installing scrubbers to its vessels, allowing them to continue running on high sulfur fuel oil after the International Maritime Organization's marine fuels sulfur limit is cut in 2020.A press release from the company said that it has decided to install scrubbers on 14 vessels including all vessels currently on order and the three LR2 vessels that were delivered earlier in 2018.These vessels have a scrubber-prepared design and there are no changes to the delivery schedule.
