The M/S Høydal, will be the world’s first LNG-powered coaster, was built at the Tersan Shipyard, Turkey for NSK Shipping, Norway. The 2,650 dwt vessel has an LOA of 230 ft (70 m) and will be powered by a single Rolls-Royce Bergen C25:33L6P engine rated at 1,650 kW at 1,000 rpm operating on LNG. Propulsion is by a Rolls-Royce CP propeller and the maximum speed is 14 kn. The is a 3,200 ct ft (90 m3) LNG tank on board and refueling is planned to be supplied from a permanent bunkering facility near the charterer BioMar’s factory, once a week. Natural gas (LNG) propulsion will make the vessel environmentally friendly and reduce emissions of NOx (nitrogen oxides) by over 90 per cent. [More]
Earlier this month the second of three Sigma Class frigates, the Sultan Moulay Ismail (#614), was handed over to the Royal Moroccan Navy by the builders, Damen Schelde Naval Shipbuilding (DSNS), Netherlands. The first frigate, the Tarik Ben Ziyad (#613) was commissioned in September 2011, the third ship (#615) is due for delivery later this year. The second and third ships have an LOA of 98 mand displacement of 2,075 t. Propulsion is by twin Pielstick 20PA6B STC diesel engines each rated at 8,910 kW at 1,094 rpm. Maximum speed is 28 kn, at the economy speed is 14 kn giving a range of 4,800 nm. Sigma offers a flexible series of variants described as corvettes or frigates. The program has attracted several export orders. [More]

Nor Lines the Norwegian logistics and shipping company has ordered two liquefied natural gas (LNG) fueled cargo vessels of 5,000 dwt with an option on two further vessels, at Tsuji Heavy Industries (Jiangsu) Shipyard, China. The ship is a Rolls-Royce Marine design for a mixed cargo vessel and follows an Environmental Ship Concept (Environship) presented at the this year’s Nor-Shipping Exhibition and Conference and winning the Next Generation Award. The vessel has an LOA of 394 ft (120 m) and uses a Bergen B Series lean burn gas engine type B35:40 V12 developing 3,930 kW (5,268 hp) at 750 rpm. A Hybrid Shaft Generator (HSG)system is specified, reducing the need to run auxiliary gensets. The shaft generator can also operate as a power take-in motor thereby providing redundancy for the propulsion system. [More]
At the end of June, the Royal Norwegian Navy received delivery of their third Skjold Class FPB vessel. The program is being supplied by a consortium of three contractors: the Norwegian companies Umoe Mandal and Kongsberg Defence & Aerospace and DCNS, France as the combat system design authority. The vessel is a Surface Effect Ship (SES), of fiberglass/ composite construction built in Norway by Umoe Mandal. The propulsion arrangement is COGAG with a father/son turbine arrangement of Pratt & Whitney ST40M of 2,982 kW (4,000 hp) and ST18M of 1,393 kW (1.894 hp) gas turbines Two diesels are available for slow steaming. The performance is record breaking with a top speed in excess of 60 kn. [More]

Rolls-Royce’s Promas integrated propeller and rudder system claims to offer gains in propulsive efficiency of between five to fifteen per cent for new builds and retrofits. The resulting benefit in practice depends on a number of factors, so each vessel needs to be considered on its merits however in most cases the payback period lies between 18 to 24 months.. Improvements can be made to FPP and CPP systems with single and multiple propellers. A Promas Lite system can be installed during a scheduled drydocking and can normally be fitted within a week.

Austal’s Auto Express 113 Class catamaran ferry Leonora Christina was handed over this week to her Danish owners Færgen A/S (formerly Nordic Ferry Services). The main dimensions are: LOA 370 ft (112.6 m), beam 86 ft (26.2 m) and maximum draft 16 ft (4.85 m), maximum deadweight 1,000 tonnes. The vessel is one of the world’s largest high speed ferries and has the highest vehicle-passenger capacity of any Austal-built vessel. Propulsion is provided by four MAN 20V 28/33D diesel engines driving four water jets producing a maximum speed of 40 kn. [More]

This week the first Advanced Induction Motor (AIM) was installed in the Royal Navy's Queen Elizabeth Class (QEC) aircraft carrier construction block at shipbuilder BAE System, Glasgow.
The ship has an Integrated Full Electric Propulsion (IFEP) system and uses four 20MW (27,000 hp) electric motors of a similar type to that used in the UK’s Type 45 destroyers. For aspects of stability the diesel gensets are located low in the ship and were delivered at an earlier stage of the construction. [More]
Hapag Lloyd displayed solid confidence in the growth of the European-based cruise business, when they recently announced the order of a new luxury cruise liner, Europa 2, from the STX France shipyard. They chose Rolls Royce engineered 'Mermaid' pod propulsion (in consortium with power conversion specialists Converteam) to propel (and steer) the new cruise liner, despite widely publicised problems with Mermaid in ships of Carnival and Royal Caribbean Cruise Lines during the past year. Mermaid Pods – Difficulties Overcome?With the increasing popularity of diesel- electric configurations as the means of propulsion for many large cruise liners, the Mermaid pod system serves both as propulsor and rudder, with an integrated electric motor directly coupled, without any gearing, to a relatively short propellor shaft; all contained within the hydrodynamically streamlined pod housing.
