Philippine Trigon Shipyard Corporation was founded in February 1978. It was granted by the Maritime Industry Authority (MARINA) a license to operate a shipyard, authorized to build and dry dock Philippine-registered ships in the same year.

It is a fully integrated shipyard facility capable of performing extensive repair works, conversion, modification and ship building using parts re-cycled from the ship breaking activities. Its cargo handling facility allows out to be very flexible in its shipyard activities because it can at the same time load or discharge ships while being repaired in its facility.
