Wind turbine installation vessel. A wind turbine installation vessel (WTIV) is a vessel specifically designed for the installation of offshore wind turbines. There were 16 such vessels in 2020.

Most are self-elevating jackup rigs. To enable quick relocation in the wind farm it is self-propelled. It also has a slender ship shaped hull to achieve a quick turnaround time with the vessel carrying several foundations or wind turbines each time. Azimuth thrusters are used to position the vessel during jack-up operations. Some vessels use the thrusters in dynamic positioning (without jacking up) to keep the vibrating pile driver steady when installing foundations. Some may carry five modern wind turbines and lift 700 tonnes  above deck. 

A vessel can cost $335 million, or $220,000 per day. A 3-year leasing may cost €90 million. 

The fleet of 16 vessels are scheduled to expand to 23 vessels by 2023, of which seven can handle the largest turbines. The fast growth of turbine size challenges even the largest vessels. In China, lack of suitable vessels are slowing the construction of offshore wind farms. 

A supplement to crane-equipped WTIVs can be crane-less feeder vessels with motion compensation. Some WTIVs have a crane but no legs.

Projects include a  crane height, and lift capacity of 1,600–3,000 tonnes. 

Some WTIV use biodegradable hydraulic fluids to minimize ecosystem impact during leaks. In Korea, some vessels are approved for liquefied natural gas. 

Construction of the four-legged US Jones Act-compliant Charybdis started at Keppel in Texas in late 2020, at a cost of 715 million dollars, scheduled for the 700 MW Revolution Wind in 2023 and the 924 MW Sunrise Wind in 2024. Such vessels require 500–800 MW of installation per year for five years to be economical. The Jones Act makes it much more difficult to install offshore wind, introducing complications of transferring parts between ships and raising costs.

Chinese destroyer Shenzhen (167). Shenzhen (167) is a Type 051B destroyer of the People's Liberation Army Navy. She was commissioned in February 1999.

Development and design 

The Shenzhen was intended to be an experimental vessel with improvements over the Luhu-class' in terms of modular construction and stealth. The ship is powered by two indigenous steam turbine engines.

The main purpose of the Type 051B was to gain experience in modern naval ship design and construction, and refining the knowledge and skills accumulated from the earlier Type 052, such as integrating many different foreign subsystems on the Type 052 more effectively.

Construction and career 
Shenzhen was launched on 16 October 1997 at the Dalian Shipyard in Dalian. Commissioned in 1999.

Shenzhen participated in the PLA Navy's first goodwill visit to Africa in 2000

Also the first visit to Europe in 2001 and the first visit to Japan in 2007.

In 2004, she received its mid-life modernization refit, with its original 100mm main gun and the HQ-7 air defense missile system being replaced by improved models.

Type 051B destroyer 167 Shenzhen visited Kochi, India for four days in August 2009, after deployment in the Gulf of Aden on anti-piracy operations.

In early 2015, she was spotted at the Zhanjiang naval base undergoing work. Initially it was unclear whether this was due to a midlife refit program or decommissioning, but pictures revealed in January 2016 that the ship was being refitted with new systems. For self-defense, the four old Type 76A 37 mm AA guns were replaced with two H/PJ-11 eleven-barreled 30 mm CIWS (export designation Type 1130), one covering each side.

In May 2020, it was revealed that the Type 051B had its YJ-83 subsonic ASMs replaced with 16 supersonic YJ-12 missiles.

Piccadilly Mill. Piccadilly Mill, also known as Bank Top Mill or Drinkwater's Mill, owned by Peter Drinkwater, was the first cotton mill in Manchester, England, to be directly powered by a steam engine, and the 10th such mill in the world. Construction of the four-storey mill on Auburn Street started in 1789 and its 8 hp Boulton and Watt engine was installed and working by 1 May 1790. Initially the engine drove only the preparatory equipment and spinning was done manually. The millwright was Thomas Lowe, who had worked for William Fairbairn and helped with the planning of two of Richard Arkwright's earliest factories.

During the early 1790s the mill employed around 500 workers. Robert Owen was employed as the manager in 1792.

Percy Martin. Percy Martin (1871-1958) was an American-born British engineer and automobile manufacturer. Born in Columbus, Ohio 19 June 1871 he obtained a degree in mechanical engineering, specializing in electrical engineering, from Ohio State University in 1892.

General Electric
He worked for General Electric in Milan and Berlin then in 1901 on holiday in England and through a chance meeting he was asked to take up the works manager's position at the Daimler Company in Coventry which he did in October 1901.

The following July he married Alice Helen Heublein from Hartford, Connecticut, they had a son and a daughter.

Daimler
Soon rationalising Daimler's range of 10 different models he promptly designed then completed the entry into production of two new cars, Daimler's 22 hp and 12 hp. He established improved incentive payments and improved the management of Daimler's design, operations and materials.

Daimler and B.S.A.
On the merging of the businesses of Daimler and arms and munitions manufacturer Birmingham Small Arms Company in October 1910 Percy Martin took up the position of managing director of the combined enterprise. He was to serve more than twenty years in that post.
World War I
In December 1916 he was appointed Controller of Internal Combustion Engines by the Ministry of Munitions and to The Air Board where he represented the Ministry of Munitions.
Airco
In January 1920 B.S.A., on Martin's say so, bought from George Holt Thomas his aircraft business, Airco. In wartime Airco had been producing new aircraft at the rate of one every 45 minutes. The B.S.A. board made the purchase presuming Martin had carried out a due diligence investigation which he hadn't. The Airco companies were on the brink of financial collapse. Though they were closed immediately the losses were so grievous that B.S.A., one of the nation's major industrial combines, was obliged to miss paying a dividend for four years.
Retirement
At the beginning of the 1930s there were boardroom disagreements, a new chairman and, only technically subject to his direction, new executives covering much of his area of responsibility. Martin remained with B.S.A. and its subsidiary Daimler until his retirement from day to day responsibilities in April 1934 at a time when in spite of the Great Depression B.S.A. still directly employed more than 11,000 people. He was appointed chairman of Daimler. He gave up his seat on the B.S.A. board after one more year.

Sleeve valves and Daimler's fluid flywheel
Percy Martin was particularly involved in two successful technical developments, the development and introduction in 1908 of sleeve valves for Daimler's engines and, in 1930, their fluid flywheel fitted to all their vehicles in conjunction with Wilsons epicyclic gearboxes and a forerunner of automatic transmissions.

Death
After retirement Martin remained in England living at Kenilworth near Coventry where he died in November 1958 a few months after his wife.

Steel industry in Bangladesh. The steel industry is an established and growing industry in Bangladesh. Predominantly based in the port city of Chittagong, the industry has emerged as a major contributor to the national economy. According to the experts, the growth of steel industry in Bangladesh is mainly induced by the rapid expansion of the country's shipbuilding and real estate sector, as well as the major investments in various infrastructure projects throughout the country.

History 
The first ever steel mill was established  in 1952 by the H Akberali Group of Industries as the "Bangladesh Steel Re-rolling Mills (BSRM)". Located at Nasirabad, Chittagong, the plant formed re-enforcing bars and structural sections. The mill gradually prolonged, adopting new technological know-how by setting up a cross-nation European mill in 1987 which incorporated a wire-rod mill. The BSRM group added a captive billet manufacturing plants in 1996 so as to make sure a stable distribution of billets of its plants. In 2006, the company installed pilot cold rolling mill to make ribbed high strength wires.

By this time, KSRM Steel Plant Ltd emerged. Very recently, they have established Billet Plant at Chittagong. Their factory situated at Ghoramara, Sitakunda at Chittagong. KSRM is a steel manufacturing organization belonging to Kabir Group of Industries. One of the largest rolling mills in Bangladesh. Moreover, several other steel companies emerged in the country, most notably GPH Ispat, RRM (The Rani Re-rolling Mills LTD, Kabir Steel Re-rolling Mills, AKS, Anwar ISpat, HKG Steel Mills Ltd., Rahim Steel Mills LTD, Seema Steel Re-rolling Mills LTD, Bashundhara Steels etc.

Market 
German plant maker SMS Group has announced  that it has signed a contract with Bangladesh based Bashundhra Multi Steel Industries Limited to build an plant in Bangladesh.

1-Nitropropane. 1-Nitropropane (1-NP) is a solvent.  It is a colorless liquid, an isomer of 2-nitropropane (2-NP), and classified as a nitro compound.

Preparation
1-nitropropane is produced industrially by the reaction of propane and nitric acid. This reaction forms four nitroalkanes: nitromethane, nitroethane, 1-nitropropane, and 2-nitropropane. 1-nitropropane is also a byproduct of the process for making 2-nitropropane, which is done by vapour phase nitration of propane.

Uses
Most 1-nitropropane is used as a starting material for other compounds. The other uses are solvent-based paints, solvent-based inks and adhesives, and as a solvent for chemical reactions.

Safety
1-nitropropane is toxic to humans and can cause damage to the kidneys and liver. The vapours are irritating for the lungs and eyes and the maximum exposure rate is 25 ppm. It is not known to be a carcinogen.

Reactions
1-nitropropane decomposes under the influence of heat into toxic gases. It also reacts violently with oxidizing agents and strong bases.

Alstom Coradia 1000. The Coradia 1000 is a type of Diesel Multiple Unit (DMU) operating in Great Britain and which is part of the Alstom Coradia family of diesel and electric multiple units. There are two types that were built, the  and .

, only the Class 180 DMUs are in service and are operated by the train operating company Grand Central.

Design
Both of the Coradia 1000 models utilise a diesel-hydraulic powertrain, with transmissions being supplied by German manufacturer Voith.
The diesel engines were supplied by American manufacturer Cummins.

When both classes were new, they featured hydrodynamic retarders as part of their braking equipment. However, due to the unreliability of this equipment on both the Class 175 and Class 180, they were bypassed with the DMUs now just using their normal air brakes.

The Class 175 and Class 180 are capable of working in a multiple unit arrangement with each other, however they cannot work with other classes.
