I have my question on the costal/offshore/ocean construction industry.

Who are the main players of costal/offshore/ocean construction industry such as building harbor/breakwater/oil rig platform in Malaysia ?
Who are consulting firms and contractors in Malaysia?
What kind of machinery is normally needed?
Who are normally the client for such projects in Malaysia?

Mind to share more background and experiences working with these companies. For contractor, I heard only sapura kencana as mahathir linked company. How's mmhe and th heavy. Are they local or oversea contractor?

Client not petronas/shell in Malaysia? I heard only ssb in Kuala Lumpur. How's the ssb link to petronas/shell in the ocean construction.
