About Us
New company. Old hands.
Oceantech was founded in 2016, but our roots go back to 1981. The family behind this company — operators of a PADI dive shop at Costabella Resort — were pioneer PADI instructors in the Philippines. We’re a family business based at Costabella Resort in Maribago, Lapu-Lapu City, with over 45 years in the water.
We built Oceantech to do things the right way. No shortcuts on safety, no guesswork on execution — just experienced divers, proper equipment, and honest work.
Our clients include 2GO, OceanJet, Trans-Asia, Lite Ferries, Cokaliong, SuperCat, FastCat, Starlite, Weesam Express, Philippine Span Asia, Cebu Port Authority, OPASCOR, and Holcim. Most of our work comes through word of mouth.
Recreational diving since 1981. Commercial diving since 2016.
