PT Oceania Prima Sejati
Smart Solutions for Industry & Maritime
PT Oceania Prima Sejati supplies shipyard equipment across Indonesia, specialising in welding systems, hull outfittings, marine machinery and high-precision electrical tools for the maritime, shipbuilding and offshore industries.
Vision
Where we are going
To be the trusted global partner in world-class welding and electrical equipment, serving a sustainable and competitive maritime ecosystem in Indonesia.

How we work
Four things you can hold us to
Built for the yards next door
The workshop is in Tanjung Uncang, on Batam’s shipbuilding belt, so parts move to the yards that need them without crossing an island first.
One supplier, eight ranges
Welding machines and consumables, hull outfittings, deck machinery, yard equipment, marine cable, fans, and treatment plants. One order, one contact, one delivery.
Specified, not just sold
Tell us the vessel and the duty and we will come back with the grade, the standard and the dimension, rather than a catalogue page.
Answered on WhatsApp
Procurement in a working yard happens on a phone. Send the list, get a price and a lead time back on the same thread.
Pillars
What we hold to
Quality assurance
Welding machinery, consumables, grinding tools and electrical equipment selected to survive a marine environment: salt, humidity, UV and continuous duty.
Technology that shortens cycle time
Submerged arc systems, automated welding trolleys, CNC cutting and plate pretreatment. Equipment chosen because it removes a step from the yard’s day, not because it is new.
Working relationships
Long-running supply into national shipyards, and manufacturer relationships that let us source a part rather than substitute one.
Less waste per hull
Right-sized consumable ordering and equipment that runs longer between service. The cheapest welding wire is the one that does not get thrown away.
Commitment
Why this matters
We would rather be a supply partner than a supply relationship. Every welding set and precision tool that leaves the workshop goes into a hull that has to hold, and the archipelago’s fleet is built and repaired one of those at a time.
