Commodore Superintendent Dockyard

What we do

BN Dockyard is the major repair establishment to provide repair and maintenance support to ships of Bangladesh Navy. It is situated on the bank of river Karnuphully. It has the capability to undertake all types of repair, refurbish and maintenance work related to BN ships and establishment with its own expertise and manpower.

History of Ship Building

Interestingly but unknown to many Bangladeshis, there was a glorious history of wooden shipbuilding in Chittagong (also known as ‘Shetgang’ in the early 4th Century BC, ‘Samunda’ in the 9th Century, and later during the 15th Century as ‘Porte Grande’) during the late 15th to the 17th centuries. This happened mainly due to the traditional boat building knowledge and the abundance of very fine quality hardwood like loha kath (Xylia Dolabiformis), segun (Tectona Grandis) and jarul kath (Lagerstromia Speciosa) suitable for shipbuilding in the nearby forested hills. Though the industry also developed near some large river ports of Bengal, Chittagong remained the most important location for building ocean-going vessels (most large seagoing vessels of that period were around 300-500 tonne by today’s measurements, a very few being around 800 tonne). Ships built at Chittagong were sturdier, more resistant to marine growth and fouling, and of better quality and longer life than those built anywhere including in Alexandria and places around the UK (where most of the then modern world’s ships used to be made). Even the mighty Ottoman Navy bought ships built at Chittagong because they were the best and also easily available. The Mughal naval fleet included a large number of ships built at Chittagong. The shipyards of Chittagong graduated to building up to 1,000 tonnes by the first part of the 19th Century. The mighty British Royal Navy also used ships built at Chittagong some such units participated in the great naval battle that took place at Trafalgar in 1805. In 1818 a ship ‘Fregatten Deutschland’ was built in Chittagong for the German Imperial Navy. The list of ships owned by the Calcutta port in 1924 included 11 English owned ships of which 08 were built at Chittagong.

The craftsmen engaged in shipbuilding at Chittagong were mostly illiterate. They acquired the art of shipbuilding as an inherited skill passed from master builders to apprentices, often from fathers to sons. In Chittagong, the low caste Hindus of Balami Para and some Muslims of Agrabad areas were engaged in shipbuilding. Chittagonian shipbuilding started waning towards last part of the 19th Century due to a complete lack of administrative patronisation from the British Raj (the British shipbuilders ultimately went for organised strikes when faced with stiff competition with the Chittagonian shipbuilding industry as the teak wood ships built in Bengal were cheaper, more durable, and also safer than those built in England) and the final death nails for this industry and craftsmanship were the advent of steam in steel hulls.

Outline of Today's Dockyard

Over the last 30 years of its history, the Dockyard has grown from a base workshop facilities to one of the modest ship repair yards in our country. Spreading over 47 acres of land, it has wide range of engineering facilities to meet maintenance need of ships and craft. The Dockyard has strength of over 1700 employees. In its 24 workshops, the Dockyard undertakes about 100 jobs on any single day. In average, Dockyard takes nearly 30 ships per year for docking and refit. All together, about 1.3-million man-hour labor worth of about 33.8 billion BDT is generated annually to accomplish the task.
