Rescue Of Roger Mallinson And Roger Chapman
The rescue of Roger Mallinson and Roger Chapman occurred between 29 August and 1 September 1973 after their Vickers Oceanics small submersible '' Pisces III'' was trapped on the seabed at a depth of , off Ireland in the Celtic Sea. The 76-hour multinational rescue effort resulted in the deepest sub rescue in history. Submersible and the crew The Canadian commercial submersible ''Pisces III'' measured long by wide by high. It was built by International Hydrodynamics of North Vancouver, British Columbia, and had been launched in 1969. ''Pisces III'' originally had tail fins, which were removed to improve access and handling when the submersible was purchased by Vickers Oceanics. Ironically, if the fins had been retained they would have prevented the entanglement of the towline on the craft's machinery sphere which caused the 1973 accident. ''Pisces III'' had sunk once before, during trials in Vancouver Bay in 1971. Peter Messervy of Vickers Oceanics, who would lead the res ...

Celtic Sea
The Celtic Sea ; cy, Y Môr Celtaidd ; kw, An Mor Keltek ; br, Ar Mor Keltiek ; french: La mer Celtique is the area of the Atlantic Ocean off the southern coast of Ireland bounded to the east by Saint George's Channel; other limits include the Bristol Channel, the English Channel, and the Bay of Biscay, as well as adjacent portions of Wales, Cornwall, and Brittany. The southern and western boundaries are delimited by the continental shelf, which drops away sharply. The Isles of Scilly are an archipelago of small islands in the sea. History The Celtic Sea receives its name from the Celtic heritage of the bounding lands to the north and east. The name was first proposed by E. W. L. Holt at a 1921 meeting in Dublin of fisheries experts from Great Britain, France, and Ireland. The northern portion of this sea was considered as part of Saint George's Channel and the southern portion as an undifferentiated part of the " Southwest Approaches" to Great Britain. The de ...

Originally a monastic settlement, Cork was expanded by Viking invaders around 915. Its charter was granted by Prince John in 1185. Cork city was once fully walled, and the remnants of the old medieval town centre can be found around South and North Main streets.

Polypropylene
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene. Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat-resistant. It is a white, mechanically rugged material and has a high chemical resistance. Bio-PP is the bio-based counterpart of polypropylene (PP). Polypropylene is the second-most widely produced commodity plastic (after polyethylene). In 2019, the global market for polypropylene was worth $126.03 billion. Revenues are expected to exceed US$145 billion by 2019. The sales of this material are forecast to grow at a rate of 5.8% per year until 2021. History Phillips Petroleum chemists J. Paul Hogan and Robert Banks first demonstrated the polymerization of propylene in 1951. The stereoselective polymerization t ...

Pisces V
''Pisces V'' is a type of manned submersible ocean exploration device, powered by battery, and capable of operating to depths of , a depth that is optimum for use in the sea waters around the Hawaiian Islands. It is used by scientists to explore the deep sea around the underwater banks in the main Hawaiian Islands, as well as the underwater features and seamounts in the Northwestern Hawaiian Islands, specifically around Kamaʻehuakanaloa Seamount (formerly Loihi). In 1973, ''Pisces V'' took part in the rescue of Roger Mallinson and Roger Chapman, who were trapped on the seabed in ''Pisces V''s sister submersible '' Pisces III''. In August 2002, ''Pisces V'' and her sister ''Pisces IV'' discovered a World War II Japanese midget submarine outside of Pearl Harbor which had been sunk by the destroyer in the first American shots fired in World War II.

Cork Harbour
Cork Harbour () is a natural harbour and river estuary at the mouth of the River Lee in County Cork, Ireland. It is one of several which lay claim to the title of "second largest natural harbour in the world by navigational area" (after Port Jackson, Sydney). Other contenders include Halifax Harbour in Canada, Trincomalee Harbour in Sri Lanka and Poole Harbour in England. The harbour has been a working port and a strategic defensive hub for centuries, and it has been one of Ireland's major employment hubs since the early 1900s. Traditional heavy industries have waned since the late 20th century, with the likes of the closure of Irish Steel in Haulbowline and shipbuilding at Verolme. It still has strategic significance in energy generation, shipping, refining and pharmaceuticals development. Geography The main tributary to the harbour is the River Lee which, after flowing through Cork city, passes through the upper harbour (Lough Mahon) in the northwest before passing to the we ...

CURV-III
CURV-III was the fourth generation of the United States Navy Cable-controlled Undersea Recovery Vehicle (CURV). CURV was a prototype for remotely operated underwater vehicles and a pioneer for teleoperation. It became famous in 1966 when CURV-I was used to recover a hydrogen bomb from the floor of the Mediterranean Sea. In 1973, CURV-III performed the deepest underwater rescue in history when it rescued two men from the ocean surface who were stranded 76 hours in the submersible '' Pisces III'' with just minutes of air remaining. The CURV-III became known in the Great Lakes region in 1976 when it was used to survey the wreck of the SS ''Edmund Fitzgerald''. CURV-21 is the current generation that replaced CURV-III.
