Hurtigruten Unveils Zero-Emission Cruise Ship
Cruise operator Hurtigruten Norway has unveiled early concept plans for its first zero-emission ship.Initially announced in March 2022, under project name ‘Sea Zero,’ the ship is being touted as "the world’s most energy-efficient cruise ship". Tasked with developing energy-efficient and carbon-neutral technology solutions, Hurtigruten Norway and its consortium of 12 maritime partners and research institute SINTEF shared key findings following its first year of research."When we initially announced the ‘Sea Zero’ project over a year ago…
A BC Ferries Case Study: Lessons Learned in Setting Underwater Radiated Noise Targets
In a typical year, the waters surrounding British Columbia’s Port of Vancouver host approximately 3,000 deep sea commercial vessels and 19 of the 35 ferries operated by BC Ferries, one of the largest ferry operators in the world. These waters are also home to a wide variety of aquatic wildlife, including the southern resident killer whales (SRKW), which have been listed as endangered in Canada since 2003.With vessel-generated acoustic disturbances identified by Fisheries and Oceans Canada as one of four key threats to the SRKW…
Propeller Considerations for Inland River Pushboats
Inland river pushboats operate in a harsh environment. Transiting our rivers, bays, lakes and inland waterways, these vessels push barges between hubs of commerce. Swift currents, trash and debris, heavy traffic and narrow waterways are day-to-day realities for these vessels and operators.Pushboats have two typical modes of operation: steady-state (long haul running) and transient-dynamic operations (backing, maneuvering and acceleration). Unlike almost any other vessel type,…
Thruster Design for Submersible Developers
Many companies involved in submersible vehicle development also look to equip the vehicle with a custom thruster. These companies typically have expertise in vehicle and drive design, but will not be experienced in propulsor design. Nor would they be expected to have the specialized tools necessary for proficient thruster design, analysis, and optimization. This article will introduce submersible vehicle developers to the design practices used by HydroComp and other specialists…
Contemporary UUV Propulsor Design
From the standpoint of vehicle propulsion physics, an unmanned underwater vehicle (UUV) is little different from your personal ski boat or a tanker. It shares the Vessel-Propulsor-Drive system model, which allows a Propulsor to convert Drive energy into thrust for the purpose of moving a Vessel. The basic principles of thrust equilibrium and motion are common to all three, as are the translation of rotational energy into axial thrust by the central element of the system – the…
HydroComp PropElements 2017- Update
HydroComp PropElements 2017 – the propeller “design for performance” code from HydroComp,Inc. of Durham NH USA – is the latest build of the company’s commercial software for marine propeller design and analysis. Propeller specialists will find it an essential addition to their software tools, and also tackles the component-level hydrodynamic needs of naval architects. Why PropElements? Still an uncharted domain for many naval architects, propeller design is an iterative process following a typical design spiral – from initial sizing through detail design.
Wärtsilä Debuts Controllable Pitch Propeller System
At the SMM exhibition and conference in Hamburg, Germany, Wärtsilä is introducing its latest development of large Controllable Pitch (CP) Propellers, based on the previously known E-hub type. The new CP propeller system offers greater efficiency and a reduced environmental impact. The new Wärtsilä CP propeller system addresses the demands of medium and large size vessel owners, and is particularly applicable for special vessels that are equipped with dynamic positioning capabilities, as well as vessels having ice notation, the manufacturer said.

Intergraph® ranks as No. 1 overall engineering design solution provider for industry in ARC Advisory Group study for the 6th consecutive year. Intergraph tops the rankings in three of five segments in which it competes – oil and gas, chemical and power – in ARC Advisory Group's "Industry" category devoted to technology used in the design, construction and operation of process, power and discrete manufacturing plants, as well as the shipbuilding and marine industries. Intergraph is the only engineering design solution provider ranked No. 1 in more than one industrial market segment.
Navy, IEEE Keep Electrical Ship Standard Current
It’s been a year since we first told you here in Maritime Reporter about the effort to update and rewrite the IEEE-45 Standard for Electrical Installations on Ships. At that time, we urged qualified experts to offer suggestions and volunteer to join in the effort as members of the committee. Thanks to those who agreed to support the committees work, a great deal of progress has been made, says Moni Islam, chair of the IEEE-45 Standard Coordinating Committee. However, he says, there is still important work to be done and volunteers are still needed…
