This company performed several large dredging and reclamation projects around Asia. A list of their projects from 1912 - 1934 includes three projects in Hong Kong:
- 1924-26: Reclamation off North Point
- 1927-29: Dredging the harbour and reclamation at Kai Tak
- 1932-34: ????
Based on that list, I've set 1924 as the year the company was created in Hong Kong. However it doesn't appear in the Jurors Lists until the list for 1926, which shows 19 employees of the company.
There must have been other projects after 1934, as the 1941 Jurors List still shows three employees of the company.
The only entry for the company in ICRIS shows them registering a non-Hong Kong Company on 13-Feb 1946. I assume this is when they set up business again after WW2. It also gives their Dutch name, NEDERLANDSCHE MAATSCHAPPIJ VOOR HAVENWERKEN N.V. In 1952 they add "Royal" to the front of their company name (and add KONINKLIJKE to the front of their Dutch name.)
They "cease Place of Business in Hong Kong" on 11th Dec 1957.
