Engineering

The core of our engineering team are a group of senior engineers from multiple disciplines (structural, mechanical, piping, electrical, instrumentation) with at least 10 years experiences in the oil and gas offshore fabrication and construction field.

We also have a number of engineering software which we usually used i.e., SACS (structure), Caesar (piping), PDMS, PV Elite (pressure vessel), Finglow (pressure vessel), etc. We have an engineering library to keep all of our engineering document, i.e, engineering dossier, as built document, procedures, standard, etc.

Procurement

Our procurement activities start from inquiries, selection of vendors, purchasing, expediting, inspection, coordination, transport and materials receiving at our yard

For importing material, our procurement department can acquire material, based on a government approved duty exempt Master List and also procure local material based on an Appreciation of Domestic Product (ADP) list.

To increase our performance, our supply chain management process we use Microsoft Axapta which include departmental requisition, purchasing, warehouse receiving, material storage, and finance

Fabrication & Construction

Gunanusa’s stellar reputation in the oil and gas field is built by years of fabricating experiences, years of delivering offshore structures to customers in Indonesia and overseas, and we have delivered more than 100 structures.

Each structure build at our fabrication yard is unique, custom fabricated by dedicated engineers determine to do their best to fulfill the customer need and schedule. From material receiving to quality control, from shop drawing to structural works, from erection and assembly to pre-commissioning our engineer and technician are working hard to ensure that we deliver the best to our customers

Hook Up & Installation

Our experienced manpower and field engineers are capable to perform on-site work hook up and installation, supported by versatile marine spreads, equipments, tools, consumable, utilities, and other resources required for site work hook-up, installation and completion.

For deck installation on shallow water or inland water, Gunanusa has the experiences and capability to use the float over method. The barge, with deck loaded, has to have transverse stability but be narrow enough to pass between the jacket legs. Stability and longitudinal strength must be adequate for both transport and at the critical stage when the deck is lifted above the barge. High capacity ballast and deballast pumps should be provided.
